[Dorset] Couple of related problems (I think)

[Tim .]

I have a couple of issue which are linked (at least I think they are)

How do I get a bash script to run at startup, it would need to run prior to the 
login screen appearing on the screen.
I have to run a single line bash script at present which is basically a xrandr 
instructions which sets the geometry for my two monitors. Otherwise I get an 
issue where both screens are unreadable and distorted at bootup sometimes.
Before I go any further lets take a step back and outline my setup. I have a 
laptop on a docking station which powers two ext monitors, due to the position 
of the laptop, the laptop screen is normally disabled and I only have the two 
monitor in use. At present I am having to use the laptop screen as it is the 
only screen that will display correctly on bootup, once I have logged in I 
don't use the laptop any further unless the both monitors display are corrupted 
then I will run the bash script from the laptop screen.
At the moment when the laptop boots up I get the customary Debian Grub screen 
asking me to select the normal boot up or the advanced option displayed on the 
laptop top screen. Once I select normal boot, the login box asking for username 
and password pops up. What I want to do is turn the laptop screen off, get the 
two monitors to display correctly (having run the script at some point during 
bootup), do away with the Debian Grub screen and jump straight to the login 
window.
Can anybody offer some suggestions?

Re: [Dorset] Where Grub??

[Tim]

Evening all

Well the testing of LMDE went seriously wrong on Sunday.

Having been in the situation where I formatted and partitioned the wrong 
drive in the past I made doubly sure that I knew where all the drivers were.


Internal SSD SDA
SDA1 root, SDA2 Home, SDA3 swap

External USB SSD SDB
SDB1 backup

External USB Disk SDC
SDC1 Root, SDC2, Home, SDC3 swap

Memory stick SDD
Single partion from which I was installing LMDE from

So based on the above I was happy I knew where everything was and what 
was going where


So the short story being at some stage the USB Memory stick became SDB, 
my backup drive became SDC and the external drive became SDD. Now for 
the strange part I found LMDE installed on both SDB & SDC (as they 
should of been), I only installed LMDE once and I did not remove the 
memory stick until I had completed the install. The install wiped and 
partitioned of my SDB (which became SDC) drive wiping out over 18months 
of backups.


I have got the drives back to where they should be, had to re-install 
grub as I unplugged the external SDC drive and wiped SDB of the LMDE 
install. I did consider having a play and trying to find out which LMDE 
was booting but by that time I was to peeved at losing my backups to care.


Finally when I rebooted after reinstalling grub (via a live distro on a 
USB stick) it still had an entry for LMDE on the grub screen so I still 
need to resolve that issue.


That will teach me to play around with a system that was working 
fine.

any sign for grub which would be right for GRUB_TIMEOUT=0 from what I 
understand.


I did try running grub-emu which is supposed to display the menu list 
which said that the file could not be found (bear in mind that dev/sdc 
where LMDE was installed, is currently unplugged)


The version of grub installed is 2.06-2ubuntu7.2 which is the same 
reported installed in Synaptic (apt gui)  on Linux Mint XFCE which is 
the installed distro on the laptop ssd, I was testing, Linux Mint 
Debian Edition (LMDE) which was installed on the external disk


So it looks like there is some Grub installed else where but is not 
stopping me from booting the installed Linux Mint XFCE

Hi Tim,


So how do I confirm if I did install grub onto dev/sda for the

My guess:

- Turn everything off.
- Unplug the external USB drive.
- Turn the PC on.
- Expect GRUB to appear, offering your old installation.
- Select it.
- See if it boots it successfully.


Once I have that information how do I go about updating Grub so I can
remove the distro I was testing and just leave the day to day distro
please.

That may depend on the style of GRUB installation set up by the
distribution.  If you have a /boot/grub/grub.cfg then that will have
‘menuentry { ... }’ entries matching what you see.

[Dorset] Where Grub??

[Tim]

Afternoon all on this typical wet Bank Holiday Monday.

I was going to test a new distro which I installed onto an external USB 
drive. During the install I realised I did not know where the current 
distro is installed. I decide to install Grub for the distro I was going 
to test onto dev/sda and I would find out for sure where I had installed 
grub for the installed distro I am using for when I was ready to uninstall.


Well the need to find out exactly where the day to day distro is 
installed came a lot sooner than intended as I had issues with the 
distro I was testing so I want to remove grub I installed for the distro 
was testing. When I boot up the laptop I am presented with a grub menu 
to select the installed distro on the internal ssd or the distro I was 
testing on an external USB Hard drive.


So how do I confirm if I did install grub onto dev/sda for the installed 
day to day distro. Once I have that information how do I go about 
updating Grub so I can remove the distro I was testing and just leave 
the day to day distro please.

‘ip a’ will show the address of each network interface.

So the IPv4 address of your NX1 laptop is 192.168.18.34/24.
That's in your new 192.168.18/24 network, which is good.


$ showmount -e
clnt_create: RPC: Program not registered

No, my showmount command included an IP address.


and this for the ssh terminal

admin@diskstation:~$ showmount -e
/Volume1/Data 192.168.1.1/24

Ah, good.  If the NAS is 192.168.18.150 then you've effectively done the
showmount I was after by running it on 150 itself.  But I still suggest
you do ‘showmount -e 192.168.18.150’ from NX1 to confirm it gives the
same result.


Is this the /etc/exports we were are looking for?

It's a subset of what would be in it.

I think the NAS, 192.168.18.150, AKA diskstation, is reporting through
showmount that /Volume1/Data may be mounted by 192.168.1.1/24.  I'm not
quite sure why the last byte of 1 is there given the /24 masks it off.
192.168.1.0/24 looks to be equivalent to me.

But your laptop, NX1, is 192.168.18.34/24 which is a different network.
The NAS won't let a 192.168.18/24 mount it as it's not 192.168.1/24.

So you need to check your other machines which can mount it are using
NFS rather than something else which has its own different set of
checks.  And if it's only the NFS machine having problems then alter the
NAS to allow NFS mounts from 192.168.18/24 instead of 192.168.1/24.


Sorry for the delay in replying.

So went onto the Nas and looked at the NFS entries, found an entry for 
192.168.1.1/24, so I added a second entry 192.169.18.1/24. I had to 
reboot the NAS but once rebooted I was able to login. My Linux box is 
the only NFS connections. So assuming I have checked my windows boxes 
can access the Nas of (think there some form of Smaba used< I am not 
sure), would is save to remove the 192.168.1.1/24 entry?

thats as far as I get. SSH is supposed to allow the basic commands like 
ls, but when I try I get nothing from command it just return the promtp. 
I have logged is an a normal user and an admin but that makes not 
difference, also tried sudo in ssh but again made not difference.


I did get this from my laptop

[Dorset] Changed IP address lost NAS, but........

[Tim]

I have recently changed my Internet Provider and that provider supplied 
me with a Linksys Mesh Router with Wifi 6


Just for personal preference and because everybody and his dog stays 
with the default 192.168.1.0/24 range I changed the range to 192.168.18.0.


There are 4 PC's that access the NAS 2 x Win10 1 x Win 11 and 1 X Linux 
(Mint). All the windows PC and see and access the NAS without issue, I 
am unable to mount the NAS in Linux, although I can access the Web 
access page from my Linux box.


The old NAS IP address was static 192.168.1.150

The New NAS IP Address is static 192.168.18.150

I have checked through all the relevant network settings on the NAS and 
they are reporting the correct IP and Gateway Address.


The NAS is ping-able from the Linux machine

I updated fstab by simply changing the IP address from 192.168.1.150 to 
192.168.18.150 and saved it and checked and it is reporting correctly.


Both NAS and Laptop have been rebooted.

If I try to mount the NAS from CLI I get the following

mit@NX1:~$ mount /media/nas
mount.nfs: access denied by server while mounting 
192.168.18.150:/volume1/Data


I have a shortcut on my Desktop (XFCE) which when I click on it to 
Mount, it gives the same error


My line is the fstab file looks like this

192.168.18.150:/volume1/Data  /media/nas  nfs 
users,rw,_netdev   0   0


All I done to edit was to add a "8" to the "1" to make "18" and then 
travelled to the end of the line and saved the file (using Nano)


Any suggestions?

Re: [Dorset] Virtual Box Problems

[Tim Waugh]

Have you tried Gnome Boxes? It's user-friendly Gnome UI for the
'native' virtualization which uses libvirtd and kvm (or qemu if
emulating another architecture).

Or, for more options and configurables, use virt-manager which is
libvirtd's own UI.

[Dorset] Euro CRA act

[Tim]

I came across a statement released by Debian about the new impending 
Euro CRA act. Debian as you can imagine has taken a strong dislike to 
anything that it see as breaking the user and release of free software.


While I have read a few documents (many of them going straight over my 
head), I am not sure where  the UK sits of supporting EU IT legislation, 
but I don't think this act is in anyway going to help the situation 
which they foresee it helping, just making it a lot worse.


Anybody else seen\heard anything about this

Re: [Dorset] Fibre Installation, Routers, telephones

[Tim]

I have taken the plunge and ordered firbe, it should of been installed 
yesterday, but three of us in the house with Covid (all over xmas) that 
was the end to that install day Covid negative as of this morning but 
still feel ill). I am not booked for 12th Jan. I went with Toob who had 
a very good deal on at the time and are one of the many City Fibre 
resellers in the area (fibre is installed by City Fibre as well). I have 
been sent a Linksys router, (Velop MX42 I think) but other than that I 
don't know much about the router.


Hope it helps

Hi All

Hope you've all had good Christmas' and the New Year.

Recently we had a visit of workers who were starting to install Fibre 
cables to replace the overhead coppers.  They said it was going to be 
Gigabit capable and it would be cheaper to install the new broadband 
connection at the same time.


Question is what router would I need (no game playing & little 
streaming) and if it affects the telephones?


What I've seen so far does not mention any telephone information. My 
next door neighbour is also trying to find out info.


Our phones are normal landlines through cables around the house, will 
we need to change these?


Miss our monthly meetings because this is the type if 'chats' we could 
have, not so easy over the 'net'.


Perhaps next weeks meeting could provide the info??

Meanwhile I'll keep looking.

Re: [Dorset] Low voltage power supply barrel connectors

[Tim]

Having had a quick look I found 2 things, one was a simple comment that 
it is 5.5mm OD and 2.5mm ID. In the article that was written in there 
was nothing that would support that sizing, no model number, nothing to 
say he bought one and it was correct, so best take that with a pinch of 
salt. Secondly there a lot of replacement power supplies for the 
Facebook portal available on Amazon these list the model numbers of the 
portal that each PSU will be compatible with. Just Google (or 
DuckDuckGo) Facebook Portal Power Connectors and you get quite a few. 
Hope it helps

My son has a Facebook Portal and his kids have mangled the barrel

gives part numbers or anything similar for barrel connectors. We have 
determined that it is 5.5mm O.D, and we have an unlabelled drill bit 
that just fits the inside hole, but trying to find the right one to 
order is stumping me.

Hi Tim,

That shows a local TCP port 56946 talking to remote port 80 on
185.151.30.148.  I can also talk to that remote port.

 $ curl -sSvghttp://185.151.30.148; echo

 It works!
 $

It does not mean the remote end initiated the TCP connection and being
port 80, the standard HTTP port, this is unlikely.  The local port 56946
is a typical port number for an outgoing connection where the port
number does not matter.  I don't know how well ufw, which is designed to
protect the machine from the outside world, can help in stopping TCP
connections which originate from within the machine.

Investigate what processes are talking to the remote IP address at the
time of the packets.

 sudo -i ss -p dst 66.39.101.110

This did not return anything


If it's a browser then check if there are service workers running or
tabs updating a page.
Nor did this, but I took it further closing down every program that 
running, one at a time and checking with wiresharkto see if the 
connection was still running. This went on for sometime until the last 
program I stopped was my VPN and thus the connection stopped. I rebooted 
we out opening anything other than what normally starts upon reboot, 
still running. Stopped the VPN from running at startup, rebooted and 
checked wireshark and nothing. Is this the expected actions of a Private 
VPN?? Regards Tim H

PIA is a VPN service
NX is Nomachine

You wrote ‘they use various port number around the 42000 to 49500 area’
but no process is listening on a TCP port in that range so Wireshark
can't be showing a TCP connection to one of those ports.

Have I got it the wrong way around and 42000-49500 is the source port
range at the remote end?  If so, what's the destination port, i.e. the
port on your machine?  And is it definitely TCP?  There should be a
process listening on it.

A TCP connection is being established after the full normal handshake?
As opposed to an incoming packet attempting to start a connection but
not progressing?  If so, a program must be actively listening on the
same TCP port to accept the connection.  What's the output of

If it's a single IP address then add it to the already existing

[Dorset] Firewall question

[Tim]

I am running Mint 21.2 XFCE and using the UFW Firewall (using GUFW) as 
well as a personal VPN to the internet.


Beginning of last week I became aware of a lot of connection to and from 
.dreamsinheels.com (no it is not a dodgy porn site). I 
use the term some sub domains as I have counted around 24 different sub 
domains so far there probably more. The connection are both ways in and 
out but greater amount of data is going out.


I have checked for Root kits but nothing was found.

The issue I have is I have not been able to block the connection, all 
the sub domains seem to be coming from 185.151.30.148 port 42474 which I 
have tried to block both in and out on both TCP & UDP with the rule to 
reject, but they are still showing as making connections. I have 
requested the action to be logged but don't see any logs. The only thing 
I have noticed is that the different sub domains seems to be using 
different ports 45510, 42474 & 43646 to name three, how do I block a 
range from 1 to 65,535 (can't remember the number of the last port).


Can anybody help with some advise please on how best to block this 
access please.

Hi Terry,


As I said, I’m surprised that any hosting provider allows
otherwise these days.

Hugh,

Can you please explain to me why using an alias (which has
previously been set up as a mail forward) is a security risk?

Can anyone explain this?

I don't see the issue with a provider of email hosting for
your-domain.com to allow you to send and receive emails from all and
sundry addresses at that domain.

Anti-spam measures SPF, DKIM, and DMARC work at the domain level AFAIK,
not at the individual email address.

Yes, to talk POP3, IMAP, or SMTP to your provider you will need to
authenticate, preferably after establishing a encrypted connection using
TLS.  It's up to the provider what you authenticate with, e.g. ‘terry’
and ‘letmein’, what mailbox that gives you access to, and what email
addresses it lets you send from.

Talk to IONOS.  If they persist in restricting their service then
withdraw your custom to send them a price signal.  :-)

Many years ago when Ionos were 1 and 1, I threaten to withdraw my 
services from them (cant remember what the issue was), by the time I had 
got off the phone my account had been terminated. Fortunately I was 
intending to to move anyway and was part way through moving stuff the 
but it still left me with several hours of panic to get everything up 
and running on my new provider.

Re: [Dorset] Thunderbird identity problems

In Outgoing Server (SMTP) under Edit >> Account settings >> Outgoing

entry, with NTLword (now Virgin) set as default address.


When I write an email at the top above the To box I have a From line and

Yes, what I'd mentioned is that resolving a dnssd address to an IP
address needs help from the printer, so if it's asleep that might be
why it stays asleep.

It's possible that changing the connection would help, to some other
type based on the IP address (I don't know what connection types
Brother printers support I'm afraid, but the GUI will). Of course,
resolving the IP address to a MAC address _also_ needs the printer's
help, but the ARP cache on the client end might help and you've said
it's a statically-allocated address.

Re: [Dorset] Window positioning and Android permanently Awake. (Was: Next Meeting - One Week Tonight)

[Tim]

In regards to gkrellm look in your home folder from .gkrellm2. open this 
folder and look for user-config file, there is a setting in there called 
"save_position" (about line 16), remove the numerical value, reboot or 
log out the desktop, move Gkrellm to the required location, right click 
on the GKrellm monitor and select configuration, select General, 
Properties Tab and select the following three options Set sticky state, 
set on top of other windows of the same type, Set window type to be a 
dock or panel, click OK. It should now stay there if it still does not 
work try changing the theme, I am using clockwork Cobalt without issue.



The running version gkrellm 2.3.11 on Mint 21.1 XFCE


Hope it helps

Hi Peter,


why does Gkrellm sometimes come up in the centre of the screen when
I start the computer, and mostly in the top left where I want it and
always move it to.

Windows are normally placed by the window manager.  These days, the WM
comes as part of the desktop environment.  I think you use Kubuntu.
Searching suggests Kubuntu's WM is called KWin.
https://userbase.kde.org/KWin

If that is the WM you're using, then that web page is a good starting
point and mentions fixing the starting position of a window as well as
linking to a page on stating general rules for windows.

I expect the default is to place it centrally if possible but move it so
as to avoid overlapping other windows if needed.  This means the end
position depends on what windows are already open and where they are.
If several programs are starting then the order of there windows
appearing may vary with the knock-on effect on Gkrellm's end position.


I didn't make last night.  My problem is the Android phone which I use
for Jitsi now stays permanently ‘Awake’, burning through 100% of battery
in about four hours.  The battery chart's detail has ‘Media’ as one of
the top two users, but the percentage of all those that are listed is
well under 50%.  I suspect Media though because clicking it shows it is
Awake for 100% of the time and used CPU for about 50% of it.  Perhaps
that's a dual-core thing.

By going through each of the Apps under Settings and doing Force Stop,
I got the battery chart's line horizontal for about three hours but then
something started it diving again on the fixed gradient to 0%.

Airplane mode doesn't help.  Battery Saver mode only changes the
gradient a little.  I've now uninstalled what apps I can, disabled many
more, including fundamentals like Phone and Messages.  The problem
probably isn't Media itself but something making use of it.  My current
suspect is Google Play.

Google finds many other people complaining of Media keeping a phone
awake over the years with no fix.  The problem started after the phone
didn't received the Government's emergency message, though that's
probably just correlation.  :-)

After pressing the 'send' button that's when it's slow, approx 3-6 
seconds: it used to go within 1 second.


Can anyone give a terminal command to find out what's happening. Not a 
frequent terminal user so bit slow to use and never really sure I've 
done it correctly (spaces or not in the commend).
Thunderbird has been through some 'upgrades' and wondered if it could 
be something in the settings but not sure what to look for. Not 
changed anything in the setup for a long time as it's always just worked.


All other internet connections are not affected and the desktop

Hi Tim H,

Is it spinning rust, which could be slow to spin up, perhaps more so if

Old style spinney disk with single usb Lead connected to the (powered) 
docking station






[E] Can't find snapshots folder.
If it is on a removable drive, please plug it in.
Waiting 30 seconds.

What happens after it waits thirty seconds for the already-mounted
drive?

Is there anything in the kernel's ring buffer around that time?

 sudo -i dmesg -Hx



The backup failed again tonight, ran the above command which did not 
list anything relevant for the time that the backup ran (all UFW Block 
entries)






If I check my backup drive it says it is mounted and if I open the
drive (clicking the icon on the desktop) it will display the folders
and start the backup

So the back-up program starts without intervention.  Instead of clicking
on the icon, because who knows what that's doing, do something simpler
like

 ls /media/backup/.../snapshots


In the 30 seconds it gives you to "reconnect" the drive I ran the 
above command which gave the following


mit@NX1:~$ ls /media/backup/backintime/NX1/root/1/last_snapshot/
backup  config  fileinfo.bz2  info  takesnapshot.log.bz2

The backup then started.

I will have to leave the 30 second warning and do nothing to see what 
happens, but I think it just fails to run based on previous error I 
have seen when it has not run






Any suggestion

dmesg is your best next step, I'd have thought.



Will investigate




Do you need the drive mounted all the time?  Could a cron job mount the
drive a minute before the scheduled backup and unmount it when it's
bound to have finished?  The theory being the just-mounted drive will be
up and running and ready to respond, not sleeping to save power.



As it only does the backups I guess i Could try mounting prior to the 
backup running. But it does not seem to be a mounting issue more 
something linked to letting the rest of the OS know it is mounted.



Thanks for the input

Is it spinning rust, which could be slow to spin up, perhaps more so if
all power comes from USB?



Old style spinney disk with single usb Lead connected to the (powered) 
docking station






[E] Can't find snapshots folder.
If it is on a removable drive, please plug it in.
Waiting 30 seconds.

What happens after it waits thirty seconds for the already-mounted
drive?

Is there anything in the kernel's ring buffer around that time?

 sudo -i dmesg -Hx



The backup failed again tonight, ran the above command which did not 
list anything relevant for the time that the backup ran (all UFW Block 
entries)






If I check my backup drive it says it is mounted and if I open the
drive (clicking the icon on the desktop) it will display the folders
and start the backup

So the back-up program starts without intervention.  Instead of clicking
on the icon, because who knows what that's doing, do something simpler
like

 ls /media/backup/.../snapshots


In the 30 seconds it gives you to "reconnect" the drive I ran the above 
command which gave the following


mit@NX1:~$ ls /media/backup/backintime/NX1/root/1/last_snapshot/
backup  config  fileinfo.bz2  info  takesnapshot.log.bz2

The backup then started.

I will have to leave the 30 second warning and do nothing to see what 
happens, but I think it just fails to run based on previous error I have 
seen when it has not run






Any suggestion

dmesg is your best next step, I'd have thought.



Will investigate




Do you need the drive mounted all the time?  Could a cron job mount the
drive a minute before the scheduled backup and unmount it when it's
bound to have finished?  The theory being the just-mounted drive will be
up and running and ready to respond, not sleeping to save power.



As it only does the backups I guess i Could try mounting prior to the 
backup running. But it does not seem to be a mounting issue more 
something linked to letting the rest of the OS know it is mounted.



Thanks for the input


Tim H

[Dorset] Inconsistent mounting

[Tim]

Hi

I am running Linux Mint 21.1 XFCE desktop on an IBM laptop with a 
docking station (IBM, specific for laptop model range)


I have an external USB drive which I use to backup to and is mounted via 
a line in fstab at bootup


UUID=d90c0c04-8484-453f-9286-ab5e40cfe62f /media/backup    ext4    
rw,errors=remount-ro    0   0


I use Backintime to do my backups, it is schedule to run daily, one 
problem is that sometimes it complains that it can not find the snapshot


[E] Can't find snapshots folder.
If it is on a removable drive, please plug it in.
Waiting 30 seconds.

If I check my backup drive it says it is mounted and if I open the drive 
(clicking the icon on the desktop) it will display the folders and start 
the backup


Here are the permission for the mount point

mit@NX1:~$ ls -l /media
total 16
drwxr-xr-x  4 mit  mit  4096 Aug 31  2020 backup
drwxr-x---+ 3 root root 4096 Dec 29 07:04 mit
drwxr-xr-x  2 mit  mit  4096 Jun 20  2021 nas
drwxr-xr-x  3 mit  mit  4096 Jan  1 21:57 spare

I have not been able to find any pattern to how often it will miss the 
snapshot


Any suggestion

Yes, and we use mermaid-js for representing upgrade paths for a specific
type of software (OpenShift operators):
https://olm.operatorframework.io/docs/contribution-guidelines/upgrade-graphs/

(Quick ref: Each operator knows which previous version(s) it can upgrade
directly from. A 'channel' is a named version stream of a particular
operator. An operator 'catalog' is a collection of operators and channels.)

I've also used sequence diagrams quite a lot, sometimes with UML along with
eg. this:
https://lucidchart.zendesk.com/hc/en-us/articles/208029986

but mostly with mermaid-js.

[Dorset] [OT] Powershell Community

[Tim]

Evening all

Sorry for the off topic question but I am learning some Powershell for 
work but I can not find a decent Powershell\Scripting community where I 
can ask questions without being attacked for asking questions.  I am not 
looking for the oversized Stackoveflow type, just a reasonably active 
site that I can ask questions. Would be interested in any other 
Powershell resource you may know of.


Thanks and sorry again for the OT subject.

There is one point that I hadn't realised about it though. KMail

Mailing List and not the Sender.  (It didn't always work, especially 
if the Sender CCd me) but it meant that I only had to hit reply to 
get the message to go to the list.


This doesn't appear to be the case in Thunderbird.  Is that so or 
have I missed something?

Re: [Dorset] New laptop

[Tim]

I would tend to agree with John, look at getting a a new or second hand 
Thinkpad, I have an old single core R51 (proper IBM 2006 vintage) which 
I upgraded with a new battery and some more memory, for less than £80, 
it runs AntiX without issue. The other Thinkpad is a T530 (IBM designed 
badged Lenovo), this is my main machine, added 8GB to make 16GB memory, 
swapped out the hard disk for 500GB SSD, picked up a full docking 
station from ebay, quite happily runs two 24" screen plus the laptop 
screen and runs Linux Mint XFCE


Hope it helps

A friend of mine is wanting a new laptop and asked if I would post his

I've always seen refurbished Thinkpads come up whenever this is
discussed. I had a new X1 Carbon at my previous job and it was a
lovely machine: everything worked well on it with Linux. When I wanted
a Linux laptop recently I looked at them and there's a big range of
specs, conditions and prices. In the end I splurged on a new XPS 13
though.


FWIW I’ve never had much luck getting fingerprint readers to work on my
laptops when dual booting  - the current Machine (asus g14) is no
exception. Everything else works fine though.

I do remember the fingerprint sensor as being the only thing that
wouldn't work on the Thinkpad initially. I think it would read with
Linux but you needed Windows to train it. At some point that changed
and I got it working properly.


I've looked at Linux built laptops including Dell and all seem to be
overpriced compared to popular Windows orientated companies.

I think it's a case of "you get what you pay for" to some extent but
the machines that are sold as supporting Linux like Dells and
Thinkpads do tend to be aimed at software devs and therefore in a
price bracket alongside Macs. It would be nice if more of the
mid-range machines were also sold as Linux compatible (since many of
them are to a large extent).

The XPS was £1100 but it's a top spec little machine. Definitely the
most I ever spent on a laptop (or any other computer come to that) but
I can't fault it.

The only thing I haven't tried to set up yet is the fingerprint
sensor! But that's pure laziness (I found I rarely used it)

[Dorset] Spam-assassin and IP ranges

[Tim]

I have a simple question regarding blocking single and ranges of IP 
addresses using the blacklist of Spamassassin to block spam site


My under standing I can block a single IP address in the local.cf file 
by simply typing in the IP address 111.222.222.111


But say I wanted to block an entire range 111.222.222.0 to 255 can I 
enter it as 111.222.222.* ?


But say I only wanted to block part of a range could I enter 
111.222.333.0 - 111.222.333.128 or maybe 111.222.222.0/128


It is worth point out at this point that I am on a hosted web package, I 
only have access to user_pref which hold the blacklist which I can edit 
freehand or update via cpanel. I do not have access to add other 
databases for Spamassassin to compare against


Everything I have read is pointed at block individual IP addresses.

(IP Addresses provided are just for explanation)

Re: [Dorset] Electricity power usage

Could do with smart socket system which are controlled by a central

I borrowed an electricity power meter  for a few days and went around 
the house measuring everything. A couple of interesting discoveries:



Total standby power of devices in the house  = 28.5 watts  This is 
sort of  invalid because the monitors on my 2 tower PC's are on a 
switch that turns them off when the PC is off so their standby power 
is less then. Also the meter seemed to register in increments of 0.5 
watts.


My new washing machine consumes 0.5 watts when not in use so have to 
switch it off at the plug in future.


My old gas oven consumes 4 watts all the time - for a clock?

My two Humax PVR's also each consume 3 watts on standby.

In use the PC's consume 49 and 79 watts each, but in sleep/suspend 
mode about 2.5.


The washing machine consumes 0.5watts when it is not in use. This 
means  1Kw every 2000  hours.   2000 hours is 83 days.


365/83.333 = 4.38  Kw/yr.  My current rate is 28.445p/KWh, so it 
costs me  £1.25 a year  just leaving it plugged in and not using it.



So just my thoughts on saving some money. A rough calculation gives a 
cost of £62.5  per year keeping the house on standby.

The reason is that there is no screen on which to display any windows.

A crontab 'job' is running in its own little login. It's a command line -only

The 'no MTA' message is a different thing. The crontab task failed (nowhere to 
display graphic output), so crontab would like to send an error report. But 
there's no email service set up for the OS to use. MTA is Mail Transfer Agent, 
which on Linux is typically sonething like sendmail, but also (typically) is 
not configured and running by default.

We only asked for the fstrim timer. 'systemctl list-timers' will show you
all the timers.

Look in the logs to see if it ran?

journalctl -u fstrim

This depends on the configuration of the timer. The 'Persistent' field
controls this (see systemd.timer(5) ).

What does this say?:
systemctl show fstrim.timer | grep Persistent

Also, find out when it last triggered:
systemctl list-timers fstrim

Re: [Dorset] LAN connectivity problem

[Tim]

How are the IP assign, DHCP or static?

If DHCP, are you sure you only have one DHCP server on the network

If on DHCP, try changing the ip renew time to something short like 2 
hours and then test?


Go to each PC and write down their network configuration, IP, Subnet, 
DNS, Gateway and then compare and make sure that are all the same (other 
than IP address)


Reboot the Netgear switch and router

Are you using a firewall\IPtables on any of the devices, can you turn 
off to test?


You don't say if there are all ethernet or mixed wifi ethernet

You could try installing wireshark on the device that are not talking to 
each other and see what wire shark says when you try to connect


Check workgroup\Domain names make sure they all have the same

When faced with a network issue these are the basics I look at, if all 
this comes back OK then we start looking for the bigger problems.

D.6 ia a NAS box that both D.9 and D.10 can and do write to.
D.6, D.9, D.10 and D.16 are connected to D.1 via an 8-way Netgear hub
My problem: D.3 cannot reach D.9 or D.10, and neither D.9 nor D.10 can 
reach D.3, despite all being connected to D.1

Re: [Dorset] Scanning did work and half-hour later didn't?

[Tim]

Most modern network capable printers have a web interface these days, 
just find the IP address, stick that into a browser and you should get a 
status page, you should also be able to get to a configuration pages for 
the device. Like Terry and Peter I always assign static IP 's I learnt 
long ago after a session of hunt the device across a lan.


Many years ago support company spent an entire day trying to connect a 
HP Inkjet printer to a Unix system including a multiplexer. Eventually 
the boss came and tried and realised that the inkjet would never work as 
it was a Winprinter (where half the firmware was delivered as windows 
software drivers). It will never work the boss shouted in frustration of 
the wasted day, he he had no answer as to why when it was first setup 
earlier in the day it printed a test page and two work related pages, 
then just stopped.

The manual refers to saving the scanned item to a folder, but is this 
folder in a storage medium in the scanner or on your computer? As 
Terry suggests, can you browse to the printers web page and find any 
'stored' scans?

The error message is: "Failed to open device 'brother4:net;dev0':

No thoughts on this.

It's configured to connect via WLAN. The IP address appears in the
router list occasionally but usually not.
For various reasons, I've always configured utility devices on my

with a static IP Address.  On my HP, I can then browse to it's Home

check its status.  Does you Brother have a web page?


After: scanimage -L
I get "device `brother4:net1;dev0' is a Brother *DCP1610W DCP1612W", so
the correct model is known about.

What did I do in the fateful 30 mins yesterday afternoon!?

I have no idea really, but since it is not always visible in your Router

be.

[Dorset] Slowing down problems

[Tim]

I am running Kali Linux (installed on ssd) on an old Fujitsu PC, spec 
wise its an old 8 core i7, 20gb of memory and a 240gb ssd and a 250gb 
spinney hard disks. Kali is all update


The reason for running Kali is that I am trying to hack my own router ( 
I mentioned a few months ago I had lost the password). I thought it 
would be an interesting fun project to learn a bit of hacking skills, it 
it gets to a point where I need to get onto the router then I will 
simply stop and reset the router.


Anyway I have produced some 6 digit wordlists, they are approximately 
329mb in size and contain around 49,000,000 words, the maximum Hydra the 
program I am using can handle is 50,000,000. Now the PC is running 24/7 
trying to crack the password. It takes around 24 to 28 hours to complete 
a single wordlist, but what I am finding is that when the PC approaches 
running  for 2.5 days the processing of attempts slows right down from 
something like 28000 to as low a 4000 an hour and then take 4 days to 
complete.


Now memory does not seems to be a problem (see below) nor does SSD free 
space 185GB in my Home partition, using ext4 format, there no high cpu, 
it bumbles around 8% per processor. PC is connected to 1gbit switch (HP 
1910) which is in turn connected to the router.


mit@NX1:~$ free
  total    used    free  shared buff/cache   
available

Mem:   16069528 2571776  816320   80320 12681432    13079436
Swap:  10238972 768    10238204

There no noticable difference when using the router when the scans are 
running at full throttle or low throttle. Rebooting the PC resolve the 
slow down issue but after couple of days it is back.


Anybody any idea why I am getting the slowdown

Regards

Well.  The reboot worked and I am now in again.  The main mystery now is why
history shows that after a Power Cycle the system stays up for 2-3 days, but
it stayed up for less than 24 hrs after yesterday's scheduled reboot..

Maybe the wind in the trees that partially screen the WiFi Antenna?  possibly,

Presumably you selected the whole of the database dump file rather than

It was a table dump I copy and pasted


Was it faster pasting it into Mousepad simply because I had copied the
text out and into Mouse pad and xed was dealing all the SQL stuff.

I've never used (or even heard of) Xed before today, but it doesn't seem
to deal with SQL. Do you mean syntax highlighting? If so, it's possible -
syntax highlighting will have a processing overhead, although I don't know
how efficient Xed is at doing that.

Some editors (eg, vim) will only process syntax for what's displayed;
others will parse the whole file. The latter approach will clearly be
slower on initial load, but faster to scroll.

How big is the dump file?


Quite small, the gzip file is only 1.5mb

The SQL file is from a blog which I broke when I moved hosts, so I am 
just dragging the raw blog text to rebuild the pages, I have all the 
text for the pages now just have to tidy it (remove HTML) then I can 
report, I have recovered and reposted about 80% of the posts already, 
just this last lot to do.


I have never heard of Xed, looks like it a stand alone program and not 
bundled with archive manager, just seemed very strange for one text 
editor to struggle handling the .sql file while another was happy to 
handle it.

[Dorset] Xed V's Mousepad

[Tim]

Morning all

I have been trawling through an old MySQL database and as it archived 
Archive Manager was using Xed to look at the file, but it was so slow. I 
extracted the file and then open it again in Xed and it was slightly 
faster to scroll through. In the end I did a simple CTRL-A of the whole 
data base and then copied and pasted it into Mousepad and it was way 
faster (I am not wanting to keep the data in MySQL format, just after 
some raw text).


Was it faster pasting it into Mousepad simply because I had copied the 
text out and into Mouse pad and xed was dealing all the SQL stuff. For 
reference I am on an i7 with 16gb of memory running Mint XFCE, all data 
is stored in my home  folder which is on am SSD.


I know I could of entered the dark arts of CLI editors but my fu is

[Dorset] Can login to router

[Tim]

HI Guys

Not Strictly Linux but marginally related.

I currently can not login into my Draytek 2926 Router, I just get bad 
username or password.


Now I know roughly when I last logged in and one of the many things I 
have on my todo list is to update the router login details, so I may 
have updated it, forgotten all about it and here we are today.


I save all my password to a password saving program (well I thought I 
had) but due to my own stupidity I only realised to day that the backup 
file for the password program is over written on a daily basis so there 
no point in trying to look back for an older version.


So other than factory reset, do I have any other options, there was only 
the one account on the router with no remote access.

Hi all

Our old PC packed up a couple of weeks ago and I've got a new 'mini' 
PC with a 250Gb SSD plus an external 2TB disk for keeping all the data 
on.  It was bought without an operating system as I want to install 
Mint 20.1.  It's mainly used by my wife, not a keen computer person!!  
But she is used to Mint.
Tried all afternoon to install Mint from both DVD & SD card(USB 
Stick).  They both work from my laptop so are 'good' medium.
The Pc is set with USB (keyboard, Mouse, external disk), HDMI to 
screen, Ethernet to Router/laptop (tried both before disconnecting them).
On switch on it does not find either the SD or DVD so reports no boot 
file.
Then tries going to the network via it's internal card. Fails and 
reports -" Start PX4 over IPv4 on MAC 1c-69-7a-6e-da-79 (it's internal 
card) - Fails then tries on "Start PX6 over IPv4 on MAC 
1c-69-7a-6e-da-79" - Fails again.


Managed to get to the setup screen but it's UEFI and I have no idea 
what half of the items are!  But did notice 'Fast start' was enabled.  
Also changed the USB items to be checked before booting. Thinking that 
would allow the system to find the DVD or SD slots - no action.


Should I disable the 'Fast start' - seem to think it should be?
Found F"=Setup, F7=BIOS update, F10+ Boot Menu & F12= Network boot.  
Not found how to set boot order as normally have it go to DVD then 
main disk.  Not found how to reorder as only options are the SSD, 
IPv4, IPv6.


Will now give up for today and look uot some back issues of Linux 
Format for inspiration.


See you tomorrow night.

Tim,

I know nothing about fish tank lighting (the last time I kept fish was 30-40
years ago and I believe it had a fluorescent light).  However, I do know a bit
about electrics and electrical design.

You can buy specialist power supplies for LEDs from places such as LED Hut

https://ledhut.co.uk/search?type=product=+LED+Transformer

but they tend to be expensive.  We used a 60 W item from them back in 2016 for
the model railway lighting (and it was half the price but wasn't dimmable).

A quick search for LED Transformer on Google yielded lots of hits with prices
much lower including:

https://www.seratechnologies.com/shop/led-transformer-12v/


The LED lights are just over 4ft long with three rows of LED's (it is a
5ft fish tank) so I guess 47 watt was the design wattage. There is a
long lead from the light about 5ft and then a small pig tail from the
power supply which then screw together with a male female round three
pin plug\socket. There is a small pig tail of about 15" inches which is
hard wired to the Power supply for the 240v mains.

I think that the three-pin plug may be a cheap and cheerful way of ensuring
that the power can't be plugged in the wrong way round, but it's possible that
the supply that you have monitors current draw and that is the sense wire.
(It's also possible that the cable dates back to the time when the company's
products were all powered directly from the mains (eg fluorescent or mains
striplight) and they had to include earth.)  If you have a multimeter, I would
suggest buzzing all three pins out to see where they go (try both ends, eg
lights to plug and plug to supply, to try to ascertain what the third pin is
connected to.

Apart from that, does the broken PSU (or light) have a brand name or Model
Number?  A search for that might provide a bit more information.


Hi Terry

Thanks for the two web site, I will bear them in mind, the only name on 
the Power supply is the light manufacturer and model number for the 
light. I have checked the mainboard in the power supply and can not find 
an name of the main board. I was though able to confirm that there are 
three cable in the output cable, a blue, brown and a black, I did note 
that the black cable was around half the size of the blue and brown 
cable. As you say I will have to use my multi meter on the pins on the 
working power supply to work out what is what.


Unfortunately this project is going to have to go on the back burner for 
a couple of week or so as I have new furniture arriving at the end of 
the week which will involve me clearing existing furniture of items in 
readiness and then rehoming into said new furniture which will take up 
me  a little while to sort out.


Thanks for the help

The only technical detail I can tell you about the power supply is

Just my thoughts: It sounds like a lot of power for LED lights.

It is one power supply driving two lights/bulbs.

Can you swap the bulbs round to check that it is not the light that 
has gone?


Assuming that you can open it up (Unplugged of course)  can you check 
that there is not a fault in one wire, or in the switch?  Of course, 
as it is for use near water it could be a potted power supply and 
inaccessible inside.


I found this at 'lightinthebox.com It might be a cheaper overall 
option? Aquarium Light LED Light Fish Tank Light White With Switch(es)

Hi Pete

Its two lights and two power supplys (of which one power supply is 
dead), both light work already tested with working power supply. Have 
looked at the dead power supply (you can take it apart) but nothing

Hi All

Yesterday my wife started her PC and got a warning notice saying there 
was on 1GiB on space left on the 'root' partition.

Checking today the following was reported:-

sda1  Ext4 / size - 24.5GiB,  Used - 22.7GiB (93%)  Free - 1.71GiB (7%).

There is plenty of space for the /Home  partition but no space on sda1 
and I can't extend it.
I checked with the disk analyser tool and it showed that the 'var' 
file has used most of the space; it's full of Flatpack folders. All 
the other folders look OK.
I remember seeing a tool that can 'clean' folder/discs but can't find 
it now.  Thought it may be the temp folder fill up the space but that 
looks OK.
Can't work out what has happened to fill the 'root' folder, no extra 
software installed and last time I looked it was only about 50% full.


If I don't do something soon then the PC will lock up And she will do 
her 'nut' (doesn't like computers  that go wrong!)



What's happening please and can I recover the space.  All above by 
using a GUI desktop, Mint 19.2 Cinnamon.

[Dorset] Intel RST?

[Tim Waugh]

Hi,

I have a laptop with a spare 2.5" drive bay I'd like to install a new disk
into (and run Linux on).

The laptop uses Intel Rapid Storage Technology, which seems to be some sort
of RAID controller. I can switch it to regular AHCI in the BIOS, but if I
do that I lose the ability to dual boot with the pre-installed OS.

Has anyone come across this before? Is there a way to stick with Intel RST
but have un-RAIDed disks installed?

Alternatively, is there a way to boot into the (Windows) installation on
the already-RST-formatted disk, after switching the BIOS to AHCI? Obviously
I could switch the BIOS back to RST if need be for booting on that, but can
that be avoided?

I plan to continue for the moment at least. Even though the aim is to find
something new, which must then go through lengthy safety trials etc, along
the way some other insight might suggest a faster approach using something
pre-existing. In any case, at this point I have no idea when vaccination
might roll out to my age group; it's still possible it would be after a
safety trial of some new discovery.

There are lots of things no-one knows about any of the vaccines, notably
how long they will last, or how long that time compares with the time it
would take to roll out a refresh.

The CPU folding is important. Some of the simulations are only made
available for CPU work.

Well, it's hard to say because of the estimated time remaining being
so broken. But some tasks have completed so we can compare.

Here is the 'bare metal' version, actually running inside a podman container:
https://boinc.ibercivis.es/ibercivis/show_host_detail.php?hostid=2288

The measured floating point and integer speeds are 6.53b and 136.5b
ops/s, and the tasks generally take about 30,000s for v0.01 and 3,500s
for v0.02.

Here's a VM I was using:
https://boinc.ibercivis.es/ibercivis/show_host_detail.php?hostid=3505

and the measured floating point and integer speeds don't seem to have
been filled in yet; they are still the default you get before you've
even submitted a completed task.

The tasks generally take about the same amount of time! But the credit
received for them is much lower -- I have no idea why that is.

I reconnected that VM using the correct project URL (oops) so now it
shows up here:
https://boinc.ibercivis.es/ibercivis/show_host_detail.php?hostid=4223

I'll leave it going for a bit to compare some more.

Ah, yes:

Thanks for the tip! I'll let these VM tasks drain until I see v0.02 tasks
come in. Still curious about how the VM tasks actually perform in KVM.

Re: [Dorset] New BOINC project that does computing for COVID-19

[Tim Waugh]

I gave up on using hibernate ('systemctl hibernate') only because the FAH
GPU task doesn't survive it.

I noticed that ibercivis released a whole load of new tasks. Still no
checkpointing, and some of them take much longer now, 8-9 hours for me.

That's a lot to lose to lack of checkpointing, so I'm going back to the VM
approach and will see how it really performs (as opposed to its
ahead-of-time estimate).

Hibernate is not only for laptops.

If you hibernate (i.e. suspend-to-disk), then you can remove the power with
impunity. When you power it back on it will resume from disk.

I'd be surprised if it's that way round. Suspend to RAM needs a battery;
hiberate does not (the machine actually powers off completely).

Instead of shutting down at night, suspend/hibernate the machine overnight
so it can pick up where it left off when it is resumed in the morning.

Re: [Dorset] New BOINC project that does computing for COVID-19

[Tim Waugh]

There are several things at play I think:
- ibercivis has not implemented checkpointing yet, which means if you
switch the computer off all running tasks lose their progress(!)
- the percentage-completion report seems to be a guess: I see it go up in
10% increments, and sometimes tasks complete earlier than the
remaining-time indicated
- some tasks appear to restart once they get to 50%, but this is expected:

Looks interesting. Are you picking up tasks from it? I haven't seen any
yet, just see this in the logs:

30-Apr-2020 09:42:04 [ibercivis] Project has no tasks available

I'm sitting on some work units for Rosetta@home as well, mostly because I'm
waiting for Folding@home to be idle waiting for work before resuming them.

But fear not: with BOINC tasks a single work unit can be assigned to
multiple clients, and the results are cross-checked.

(The 'I resumed boinc' was me)

I've not seen rosetta@home waiting for work units yet so I'm not sure what
would cause it. Although, I'm only running it when folding@home is idle. I
only have a single fairly low powered dual-CPU (Turion) machine spare to
use, which I notice comes very far down this list:
https://boinc.bakerlab.org/rosetta/cpu_list.php

Nice article here, folding@home the main focus, which mentions back-offs
when requesting new work:
https://www.extremetech.com/computing/308332-foldinghome-crushes-exascale-barrier-now-faster-than-dozens-of-supercomputers

The Folding@home project definitely seems better at publicity. :-)

Also WCG is World Community Grid, not currently researching COVID-19
specifically:

Do you have the boinc-manager installed? There is a graphical interface,
where you can find Options → Computing preferences with inputs like:

Use at most [ 100 ] % of the CPUs
Use at most [ 100 ] % of CPU time
[x] Suspend when computer is on batter
[ ] Suspend when computer is in use

Further down there is also:

Request tasks to checkpoint at most every [ 60 ] seconds

which answers your question about how much work might be lost when
switching off.

I don't think that's necessarily a huge drawback. The overall computing
power comes from numbers of CPUs/GPUs as well as individual processing
power. My system is dual core but each CPU is slower than that (2.2GHz).

Not sure which two methods you might mean:
* bare vs container
  - No difference. Containers are not virtualized, they run directly on the
CPU. Probably not work bothering with containers for this unless you're
already used to them (or fancy playing).

* BOINC vs folding@home
  - I think either can use as much idle CPU as you want to give it. For
folding@home there is a slider on the web interface for power:
'light-medium-full', and also defaults to doing work only when the computer
isn't otherwise in use.
