[Linux-users] ssh connection timed out

[Roger Searle]

Hi, I am trying to ssh to a Ubuntu 8.04.4 LTS virtual machine - 
temporary host is an XP box running VMWare Server 2.02.  Previously when 
hosted on an ubuntu box I could ssh to it, whether this move has 
something to do with this breakage or not I'm unsure.

The VM appears to function normally in other ways.  I can ping it from 
the network by name or IP address, I can ping from it by name or IP 
address.  I can ssh from this box to another on the network.

I believe the daemon is running and listening on port 22:
ro...@neptune:~$ sudo /etc/init.d/ssh restart
  * Restarting OpenBSD Secure Shell server 
sshd
   
[ OK ]
ro...@neptune:~$ sudo netstat -anltp | grep sshd
tcp6   0  0 :::22   :::*
LISTEN  6464/sshd

Nothing relevant in iptables:
ro...@neptune:~$ sudo iptables  -L
Chain INPUT (policy ACCEPT)
target prot opt source   destination

Chain FORWARD (policy ACCEPT)
target prot opt source   destination

Chain OUTPUT (policy ACCEPT)
target prot opt source   destination

Nothing but commented lines in /etc/hosts.allow and hosts.deny.

Error is always this:
ro...@mercury:~$ ssh neptune
ssh: connect to host neptune port 22: Connection timed out
(same with ssh ro...@neptune or ssh ip-address)

This also:
ro...@mercury:~$ telnet neptune 22
Trying 10.2.1.202...
telnet: Unable to connect to remote host: Connection timed out

Here endeth my efforts.  Can anyone suggest where to from here?

Cheers,
Roger

Re: [Linux-users] Dependency probs on OpenProj

[Roger Searle]

Plenty of google results on this type of error, seem to be bugs in a 
package that often later resolve themselves when running an update (e.g. 
when running sudo aptitude update;sudo aptitude safe-upgrade).  Times 
I've seen it I have not done anything and not noticed any issue.

Does openproj run OK, or do you notice any errors or issues of any type 
on your box generally subsequent to installing it?

Roger

Re: [Linux-users] virtualbox host blue screen on startup

Thanks - I had all the APIC etc stuff the same, ended up being that the

 However logging back on as my own user the VM will boot without issue.

 I've checked the permissions of the VDI file and given all users rwx,
 not made any difference.

 I haven't located any relevant answers yet in my googling and wonder if
 anyone has some experience of this or similar they might like to share?

[Linux-users] delete huge nest of folders

[Roger Searle]

Hi, over the holiday period some weirdness occurred and rectifying is 
proving troublesome.  On a USB drive I have a very deeply nested folder 
structure of the same repeating name which probably ultimately ends in 
the same name and has a few 100MB of photos in it i.e. 
/media/drive/2003/2003/2003 (repeat many MANY times) 
/2003/somephotos.jpg.  Attempting to do rm -rf may be doing something 
(shows in htop, taking a few % of a core) but a few hours later is still 
not done.  Looking at the properties of the top level folder in a file 
manager, it reads for ages trying to determine number of folders and 
gets to a brick wall at about 140,000 folders and kills my KDE session!

Some googling isn't really getting me anywhere, ideas like this do not 
finish the job after a couple of hours:
ls | grep 2003 | xargs rm -rf

Any suggestions on how to remove the offending folders in some quick-ish 
and recursive fashion are welcomed, while leaving other folders in 
/media alone.

Secondary importance is ideas on how the situation arose in the first 
place might be interesting.  Possible relevant factors: a 1TB USB drive 
encrypted via TrueCrypt receiving backups via rsync, the host machine 
had a power failure on the boxing day quake such that the power cable to 
one of the internal hard drives (containing /home) came out and left the 
machine in a partially useable state.  Other top level folders on the 
same USB drive are fine.

Cheers,
Roger

Re: [Linux-users] delete huge nest of folders

[Roger Searle]

Thanks Jim and Craig for the suggestion to do fsck and possibly write 
off the partition, as noted it is a backup drive and 1 of 2 that are 
regularly rotated because you never know when something might go wrong! 
I expect (and will check) that my rsyncs will have the correct files 
copied over next time I use that drive, it will just be a longer than 
normal sync.  Not that it matters because it will be out of hours anyway.

So I'll consider the problem solved.

Cheers,
Roger

 So you have a structure of many directories, and at the bottom a set
 of files? Or something different?
 I presume you've removed the files at the bottom OK?

 /media alone.
 Errm, unlink() the top one (/media/drive/2003/2003 ?) using perl or C
 or something that isn't the shell, then unmount and fsck the
 filesystem :-) Then go remove anything left in the
 /media/drive/lost+found directory ...

 That's a little dangerous though, but if you like living on the edge, go for 
 it.

 Also, given that this is a backup drive, don't bother preserving the
 rest of /media/drive, consider nuking it completely with mkfs, and
 then re-establishing the backups.

 Not sure what caused your problem, but I like to leave marker files on
 my mount pounts, where they exist when a device is unmounted (i.e. not
 /media/...)

 So when my drive is unmounted I might have /data -- so in there I'll
 create a file called /data/STOP. When the correct device is mounted
 onto /data, this file effectively disappears -- so I can check for it
 in the top of any simple backup scripts ...

 if [ -e /data/STOP ]
 then exit 1
 fi

 This helps to detect unmounted directories, without having to know
 anything about how they are mounted in the script.

 Well, if you are writing it off, how about trying the unlink/fsck
 trick and see if that helps? I'd be keen to hear from someone using it
 in practice ...

 -jim

OK - but I got kind of stuck, and time pressures took me right to write 
it off.  The drive must be mounted in TrueCrypt to be able to write to 
it, and while it is I got:

roger@mercury:/usr/share/man$ fsck /media/truecrypt1/
fsck from util-linux-ng 2.17.2
e2fsck 1.41.11 (14-Mar-2010)
fsck.ext2: Is a directory while trying to open /media/truecrypt1

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
 e2fsck -b 8193 device

So first question: Does fsck correctly know it's a corrupt superblock 
given it's encrypted?

If I then unmount the drive in TrueCrypt, it does not show in the 
results of the mount command.  This being the point at which I decided 
to move on!  I've not yet done a mkfs.

How would I then run fsck without a TrueCrypt mount?  Or is the unlink 
suggestion done via other means?

Cheers,
Roger

[Linux-users] start openvpn automatically

[Roger Searle]

Hi, I have an OpenVPN server installed and configured on Ubuntu 10.10 
and works well (clients can connect), except it doesn't start 
automatically. It starts fine from the command line, and I see that in 
/etc/init.d I have openvpn, and in each of /etc/rc2.d, rc3.d, rc4.d and 
rc5.d there is a S16openvpn - ../init.d/openvpn link.

What do I need to do or where do I need to look to have the server start 
automatically to run as a daemon or service?

I'm not clear from my googling just what needs to happen, aside from 
perhaps it needs to be further down the boot order via S99 instead of an 
S16, though I'm unsure of the best way of implementing this or if 
there's other issues I need to understand.

Cheers,
Roger

Generally, just put the server config file into /etc/openvpn,
called_something_.conf

The init script isn't OpenVPN itself, it's just a script that searches
for config files and invokes OpenVPN with them, if they are there.

-jim


I suspect I created the situation by leaving a second .conf file (for
clients) in /etc/openvpn.  Looks like everything else was as it should
be.  The opportunity to re-test is Monday morning.  Thanks to everyone
for their replies, confirmations, other options - which would only now
be renumbering the various rcX links.

Cheers,
Roger
Server reboot and OpenVPN restarts  now there's the single .conf file.  
Thanks for the replies.

[Linux-users] time stamp in bash script

[Roger Searle]

Hi, I have various bash scripts for backing up to S3 storage, run via 
s3cmd and cron which kindly sends me a nice email with the output of 
either s3cmd or  echo 'some text'  lines in the script.  One such 
script for user emails changes to bob's email folder, does the backup, 
changes to jane's email folder, backs up etc.

I'm interested in knowing how long each user's backing up takes by 
putting a time stamp in the script at the start (after changing to the 
user's folder, before the s3cmd runs) and end (after the s3cmd runs) via 
date +%H:%M:%S.  I can then make a comparison between the 2 myself to 
see elapsed time (or later extend the idea to get the difference between 
the 2).  I could do this maybe:

echo start time:
date +%H:%M:%S

and think this will work but it would be nice if I could get this on a 
single line, however I'm confused/lost about the finer (important) 
points of where quotes need to go and when they should be single or 
double. Could someone clarify for me please?

 we'll stick to 32 bit.

 Cheers
 Yuri


Regarding flash, I can happily report that both my main work and home 
desktop machines, 64bit Natty, both have functioning flash including 
(importantly) sound.  This is the first time I have got to this state.  
I have not made any effort to fix/install/do anything other than a 
distro upgrade.  Something of a relief.  I can't say why, I'd only guess 
that it's due to sufficient maturing on the part of 
Ubuntu/Adobe/developers and don't care, happy in the knowledge that it 
Just Works.  I long ago tired of the random outcome of the next flash or 
distro update and what state I would find things in, and what the 
solution might be (it seemed that it was always a different cause/solution).

Only minor issue I can comment on is a flickering and invisibility of 
the progress bar in the player on the home desktop, which I currently 
have no energy for investigating.

Cheers,
Roger

[Linux-users] moving grub to another partition

[Roger Searle]

Hi, I'm running Linux Mint 11, a second OS install on this box, the 
first being various k/ubuntus ending at Natty.  I'm not interested in 
the Natty install now and want to make use of the partition for 
something else, however this is where the working grub is installed.  
There is a second grub (/etc/default/grub, /etc/grub.d/) for the Mint 
install, however editing of this /etc/default/grub and running 
grub-update have no effect on the grub menu when the machine boots, 
leading me to realise I have 2 grubs.  I've done enough googling to 
get me this far and realise I don't really know what I should do to have 
the box use the grub files in the Mint install, the likely outcome would 
be rendering it unbootable and needing to reinstall grub.  Could someone 
point me in the right direction please?

Some more info that's probably relevant: sda6 is where the Natty 
installation is, sdc1 is / and sdc6 is /home for Mint.  The single 
partition on sdb (sdb1) is my /video, the fact that it has the bootable 
flag set may be a hangover from a previous install.  And of note, sdc1 
does not have the boot flag set.

Re: [Linux-users] moving grub to another partition

[Roger Searle]

Normally I'd be OK with that approach, however this is now a well 
behaved mythtv box, so not keen!  Looks like Kevin's suggestion of an 
uninstall then reinstall is the option, or do nothing.  Thanks for the 
replies.

 I've often thought of partnering with someone in a different city to

 I back up my office server to amazon s3 every night and get bills in

 up with someone else, and ensuring their server is up when you want to
 back up, and vice versa, and their hard drive isn't about to die, that
 the data on theor machine is encrypted etc etc I think amazon provides
 a good solution.

 The advantage is that you can partner with someone you know and trust.

 yes, but I value the uptime and ease of use of amazon much more.

I'm an S3 fan too, once set up it's just a matter of reading an emailed 
log of what last night's cron job did.  To help speed the process of a 
restore to another site a sync back down can be performed now and then - 
doing that just now it took 10 minutes to get changed files since last 
week, could make it much quicker if it was run hourly.

 I have to admit I haven't seen a simple partition table like that for ages.
 Why did you put swap first on the disk?
I have no idea, other than to say the various disks in the box have come 
and gone over the years, been in there varying times and it has been 
through quite a few reinstalls and new installs, various partitions have 
been removed and recreated as a result.  And of course I sometimes don't 
use my brain very well...  It will have become swap on a second 
drive.  This current install has /, /home, swap, all on sdc. 4 drives 
in there right now.

Your pv/lvraid info below is very interesting, no questions right now.  
I've temporarily resolved my mythtv disk space issue with creating 
another storage group using a spare partition, but thanks for the 
insight into another possibility which I've not played with before but 
am keen to.  I definitely need a new drive for this box at some point 
soon. It may well coincide with building a front end box when funds 
allow - the above sda and another coming out, a TB (or 2) going in.

 By contrast, here's my desktop, which is still FC13 based.



  Device Boot  Start End  Blocks   Id  System

 which leads to:

 So /boot is a raid1, the machine could use either to boot.   When the OS
 is up, both bits are synched.

I put 8GB of RAM in my current work desktop machine, htop tells me

up someone's current and underspec'd purchase.  More RAM in a windows 
machine always helps.  If no spare slots for adding, then replace.  Good 
for current generation, poss. a bit pricey for the previous, not worth 
it for the one before that.

On another tack, I've just seen for myself what a huge difference the 
window manager makes.  I put mythbuntu 10.10 (for a front end) on a box, 
an Athlon dual core 1350 MHz with 4GB RAM.  It uses xfce, and has 
blazingly fast boot time: POST is the usual 11 secs, desktop (including 
an auto log in) a further 19 secs!  Mythtv loaded ready to select a 
recording for a total time of 50 seconds from pressing the power 
button.  Loading an application like Firefox happens in a snap.  Shut 
down takes about 3 seconds.  A bit different from the usual KDE 4.x or 
XP/7 experience, that's for sure.

[Linux-users] internal openvpn through pfsense

[Roger Searle]

I've put a pfsense install on an alix box - some [0]nice gear from the 
nice people at nicegear.co.nz - to replace an ipcop 1.4 box that was 
approaching 10 years old.  On the LAN I have a Lucid LTS box running 
OpenVPN, previously I had UDP/1194 open on the IPCop box and on the DSL 
router, and could connect nicely.

I'm not clear how (or if) I can do similar port forwarding on pfsense, 
seems to insist on on being the OpenVPN server itself if I choose 1194, 
therefore use it's certificate manager etc, effectively leading to 
abandoning a perfectly good OpenVPN service.

Do others have an internal OpenVPN server working OK through pfsense?  
Is the right approach to use a different port inside the DSL router, for 
example, forward UDP/1194 from the internet to UDP/1195 on the pfsense 
WAN address, have a pfsense WAN rule for UDP/1195 and NAT port forward 
to the OpenVPN server's IP address, and have the server listen on 1195?  
This is what I am trying without success so perhaps I am overlooking 
something further or this is a bad approach, any feedback to resolve 
this would be appreciated.  Clients attempting to connect give this in 
their log indicating the firewall blocking:

Mon Dec 12 11:49:38 2011 TLS Error: TLS key negotiation failed to occur 
within 60 seconds (check your network connectivity)
Mon Dec 12 11:49:38 2011 TLS Error: TLS handshake failed

 Excellent choice - I'm doing the same with a 2D2, but everything is on
 vlans on one port.   Its supposed to do this in 5 watts. I have an intel
 mini PCI NIC in there too, next thing to do is set all that up and
 replace the old dlink AP.
 Do others have an internal OpenVPN server working OK through pfsense?
 Not personally, but all you need to do is disable the openVPN server on
 the pfsense box, and NAT port 1194 UDP through to the internal host.
 Shouldn't be a major change.   I have SMTP, ssh, etc natted through to
 various internal hosts.
Thanks for the replies and please forgive the apparent stupidness of 
this question - but where/how is the openvpn server disabled?  Is it 
sufficient that on VPNOpenVPN page that the server and client tabs both 
have no entries?  Otherwise where else is this done?  I have looked and 
googled and looked and feel increasingly dumb.

I'm kind of back where I was to start with, configuring NAT port 
forwarding and Rules for UDP/1194, the internal box is on 1194, the DSL 
router forwarding 1194.  After a save/apply of the rule, always it 
returns to:

Interface: WAN
Protocol: UDP
Source port range: (from and to) OpenVPN (where I had manually entered 1194)
Destination: WAN address (as suggested by the docs)
Destination port range: (from and to) OpenVPN (where I had manually 
entered 1194)
Redirect target IP: 10.2.1.201 (the internal server's address)
Redirect target port: OpenVPN (where I had manually entered 1194)

And clients continue to get the TLS handshake error and restart every 2 
minutes.  Anything looking out of place here?

Roger

Not that model, though a few weeks ago added a TCL supplied WNR1000 I 
had sitting around unused to my home network to have as a second 
wireless network, similar to your situation in that I'm using it as an 
access point only (not using DHCP or the WAN port).  It has all the

Just works, bonus is the wireless light flashes very brightly so your

Maybe it's just the plugins I use but I'm getting really tired of 
it.   Frequently my desktop is locking up completely with disk io so 
badly that the desktop and mouse starts locking up for 30-60 seconds 
at a time.  If I'm lucky I can manage to kill firefox and wait a 
couple of minutes for the io activity to calm down to get a responsive 
desktop back.


I love Firefox but find myself using Chromium more and more often.

Surely memory leaks in firefox and popular addons should be improving 
over time, not getting worse...


Does anyone else have similar problems with Firefox?

Kubuntu 11.04 64bit, 6Gb RAM, good fast CPU, lots of disk.


If it's happening frequently enough, maybe you could make an educated 
guess and turn most add-ons off, or just turn them all off, turning back 
on slowly enough that you can pin down the offender?


As a former firefox devotee, I'm happy on chrome these days though at 
home approx. weekly will get a cpu core hitting 100% which htop reports 
being chrome.  I'm certain it is some bit of flash wonderment rather 
than chrome as such, though I have no inclination to figure out which 
site(s) is responsible given the frequency.  Only mentioning since it's 
unlikely there's no browser experience totally free from issue unless 
you are using lynx.  Which has a different set of issues . . .

my trusty linksys wrt54gl and on to various linux boxes primarily my 
mythtv back and front ends, and mint desktop.


Efforts to set up port forwarding fail simply in that the save button, 
while appearing to click, just will not function to actually save a set 
of start/end ports, protocol and destination IP address that is 
entered.  This device is fairly close to the factory settings, only 
having changed the LAN IP addressing to be 10.1.1.0/8 so as to be 
different from the network inside the linksys.  NAT is enabled on the 
relevant virtual circuit, I am using the virtual servers section under 
Advanced Settings  NAT on page 24, 25 of the manual below if that is 
helpful for anyone wanting to see what I see.  I've attempted numerous 
variations of port numbers, protocol, using built in application combo 
box or custom entry, and am yet to see an entry appear in the listing of 
rules.


I have already updated to the latest firmware, tried multiple browsers 
(even resorting to using IE) all to no avail.  My googling fails to find 
anything that helps.


Does anyone have experience resolving a similar situation? Where a 
button of some sort won't work initially?  Or have any suggestions what 
I could try?  It seems to function in any other regard, so not 
physically faulty, I wonder if some other setting means the virtual 
server settings won't save, but really have no clue what/where.


This is the router:

Re: [Linux-users] slow write speed to USB ports

[Roger Searle]

Hi, thanks for the reply and suggestions.  lsusb shows 3.0, 2.0 and 1.1 
root hubs, more tests (ssh to box, use cp command) on all the USB 
ports give similar times, between 5:00 and 5:45, giving me speeds 
approaching 20mbps.  The motherboard specs say all rear ports and 
headers (for front panel) are USB 2.0 (or 3.0).  I see that the 1.1 hubs 
use ohci_hcd driver, 2.0 the ehci_hcd, and 3.0 the xhci_hcd drivers, 
though this doesn't offer me any clarity about what may be the issue or 
where/if I can improve the situation.


Sadly further testing with other boxes is suggesting I have rubbish 
transfer rates via USB other places too.  And that the above stick will 
receive the same file in 2:00 via Windows.Any other suggestions are 
appreciated, but at this point it looks like I return the box to it's 
owner stating that USB copies will be s  l  o  w . . .


Cheers,
Roger

 Since we know that the stick does copy quite quickly on a different

However,  the listing on the usb devices is the giveaway.

Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Device Descriptor:

  bDescriptorType 1
  bcdUSB   1.10  -- this means that it is usb 1 
(seriously slow).


lines like the above suggest suggest that there are usb 1 devices - or 
the hub is slow.


I could work out from the listing what the fault is, but it is 
simplest to say;

a)take all usb entities off the computer.

a.1)reboot the computer if paranoid

b)ssh into the box from a second computer

c)put the usb device into the usb sockets at the back, which are 
directly connected to the motherboard. (rather, are on the motherboard).
  ***The usb sockets at the back, which are on the motherboard are 
most likely to be usb2. The other sockets may, or may not be usb2.


d)now try the file copy operation, which should be quicker.
   If not quicker, move usb stick to another socket on the back and 
try it. At this stage, it is all bad..


e)now attach other usb devices, and see what the times are - or try 
other usb sockets and see what the times are. This tells you which

   socket (or devices) are usb 1.


Above is fault finding the simple way Delving through listings can 
be tedious..

The times I have measured are for the displaying of the file copy

[Linux-users] postfix config

[Roger Searle]

Hi everyone, I have an Ubuntu server 10.04.4 LTS box, I want to 
understand more about how it sends emails, replicate on other boxes, get 
some goodness such as nagios alerts going out, for example.  I know my 
knowledge in this area is quite weak.


The configuration details (related to the MTA at least) were not 
documented during install.  It's clear from /var/log/mail.log that 
postfix is the MTA.  I can read system emails via mail.  Output of 
cron jobs are being emailed successfully to an external address 
specified in the MAILTO= line of each crontab.


crontab MAILTO addresses set as u...@mydomain.com however will NOT 
arrive.  I believe that somewhere I have unwisely set the box's domain 
to be mydomain.com since when I view system emails via mail they are 
going to r...@mydomain.com.  What config file am I needing to edit to 
put the box in some other internal domain so it can send messages out to 
mydomain.com?  If I am not on the right track here, could someone nudge 
me in an  appropriate direction?

Why Zone minder?

I specifically put motion on the not-myth server, purely to avoid 
potential confusion with v4l and /dev/videoX nodes.

Possibly could merge them these days of /dev/dvb/  but can't be bothered.
That's sensible putting on a different box but sadly I don't have 
another one available for that.  It is pretty well specced, quad core 
Phenom, 8GB RAM.


Initially I didn't even know if there was linux support for the camera, 
I saw it demo'd in the neighbourhood and knew that I could at least run 
it through an XP vm.  I knew of ZoneMinder via there being the MythTV 
plugin, which I've not really looked at.  I did ask a question on 
(this?) list at the time about IP cameras, I don't recall there being 
any replies.


That particular camera was quite easy to get a stream to VLC.  It didn't 
take too long to figure out the slightly different incantations to have 
it work in ZoneMinder. I've never noticed any issue with it and MythTV 
which is via /dev/dvb.


The main issue I have with the setup itself is that our drive is very 
long, and it's views from the garage to the road have several trees 
which means motion detection won't work reliably. This is despite being 
able to create zones in the view where the trees are to ignore motion 
triggering the recording.  It just means it needs to record 24/7 and 
needs a suitable (large) amount of storage to retain some weeks of 
recordings.

I'd add that if I am coming in to a thread as the 2nd or subsequent

My personal view is that top posting is the default of most mail

to not swim against the tide.

Far too much time has been wasted in petty email wars over top vs

my view: Edit wisely, write clearly, and top post.

Re: [Linux-users] Box is locking up

[Roger Searle]

I have sometimes experienced this kind of thing and agree it is usually 
indicative of faulty hardware, however have also found it can be caused 
by graphics drivers, particularly if the box has just gone through a 
major distribution upgrade.  These days it's the thing I (slightly) 
worry about causing some inconvenience on an upgrade.  Happened on a 
couple of ubuntu boxes I took to 14.04 LTS recently.


Sadly, the fix isn't necessarily ensuring the latest drivers are 
installed, it can mean going back a version.  It's a bit random, and 
somewhat frustrating . . .


Also sometimes, the fix for issues following a distro upgrade is running 
the apt-get update/upgrade (equivalent for Mageia) as this might pick up 
something missed first time round?


Good luck with it all :)

[Linux-users] modem recommendations - VoIP on 2talk

[Roger Searle]

Hi everyone, I am seeing experience or recommendations on a reliable 
modem/router for our in-house VoIP system (FreePBX / Asterisk to make it 
list relevant) to replace one that is now showing some unreliability.  
Service provider is 2talk on an ADSL line dedicated to VoIP.


We initially had a recommended DrayTek Vigor120 which wouldn't ever 
establish a trunk (SIP peering) with 2talk despite the best efforts of a 
(well-known on this list) expert.  Whereas a cheap Belkin thing we had 
spare would work - this is the device that is now needing replacement.  
The 2talk support pages are often not very helpful or out of date, 
however the BYOD requirements listed include SIP V2 or above compliant, 
one of iLBC, GSM, G.711 codec (our server uses gsm), T.38 pass through 
(for faxing), and support for H.264 or H.263 (future proofing for video 
calling).  I'll admit to total confusion about PPPoE/PPPoA/passthrough 
requirements.


Any specific models anyone has found to be good, including better/other 
DrayTek devices, in particular with a 2talk service, would be welcomed - 
with first lot of thanks in advance :)

The Draytek routers can definitely be problematic with SIP! I've had

However there is another less drastic trick you can use since you're 
using 2talk. In essence, one just needs to avoid the broken SIP ALG 
code in the NAT portion of the router. Ironically, simply disabling it 
via the router's UI often doesn't work (speaks volumes about the code 
doesn't it), however it can very easily be achieved by simply changing 
the signalling to another port, if your upstream SIP host supports it. 
This effectively bypasses the ALG completely. So much for DPI! It 
never looks any further than layer 4.


Luckily for you, 2talk do support an alternative port! Just use port 
'50600' instead.


Hope this helps,

Any specific models anyone has found to be good, including 
better/other DrayTek devices, in particular with a 2talk service, 
would be welcomed - with first lot of thanks in advance :)


Cheers,
Roger

Re: [Linux-users] startup woes

[Roger Searle]

Sorry to hear :(

Motherboard failure?

Hi All, the heading understates my problem - I can no longer boot my 
desktop!!!


The setup is I have 2 hard drives, 1 with 6 ptns and the other with 8. 
Each drive has (or should have) 2 bootable ptns. I am using grub to 
start any one of them but none work. All attempts to reinstate boot 
records have failed and the mbr has some funny entries.


Rescue disks on hand include install disks for Mageia 4, and Mageia 5 
and a live dvd for Mageia 5. Also a Knoppix 5 disk and a 
Boot-Repair-Disk. None of the install disks appear to be writing to 
the mbr.


Does the live dvd run in a ramdisk only? I have tried to set up a 
bootable ptn (sdb1 or sdb6) from this disk several times but it does 
not appear to overwrite the mbr by the look of the choices when I 
reboot. Also tried to make small changes which should show up on a 
real disk later


The last install from the live disk was to /dev/sdb, with bootloader 
grub on /dev/sda . This time the grub menu was correct. It started to 
boot but stopped when dependencies failed for sda9 (swap) and sdb5 (data)


Help and condolencies will be most appreciated

Barry

Re: [Linux-users] Thunderbird woes cont.

[Roger Searle]

When you right click the account name in the left-most pane > Settings > 
Server Settings, is the Local Directory set to the folder your profile 
resides in?  I have several accounts in my current install, they end 
with the following path (one per account)


\Profiles\w92z88kc.default\ImapMail\imap.googlemail.com
\Profiles\w92z88kc.default\ImapMail\imap.googlemail-1.com

If not there is a browse button to point it to the correct place.

Another option: from the command line, run "thunderbird 
--profilemanager" (note 2 hyphens there) where you can create (or delete 
or rename) a profile, from where you can choose the folder containing 
your existing folder.


Good luck - sorry I can't help in person.

Cheers,
Roger

[Linux-users] bbswitch boot delay

[Roger Searle]

Hi, can anyone help me interpret the following lines from dmesg. This is 
on a new i7 laptop with SSD drive that should be booting in under 30 
seconds but has this 90 second delay involving bbswitch. The ACPI 
Warning line here also shows up 20 or so times 1 second earlier, and 
then a few times later (at 103 seconds).  My reading about bbswitch took 
me to confusing, sometimes conflicting, often not current, info on 
disabling modules, changing graphics drivers, or other suggestions with 
potential to disrupt DayJob for long periods!  I'm not at all clear on a 
good approach here.


Any pointers on where/how to investigate further are welcomed.

Regards
Roger

Re: [Linux-users] GNU/Linux support Weds 7.30pm

[Roger Searle]

Some interesting project topics there Robert, I'd be interested in 
coming a few times a year (but doubt I could manage monthly)


Cheers,

Hi Rik (and all),

I have never been to one of your sessions, mainly because I play 
basketball on Wednesday nights.


Reading your reminder emails I get the impression (maybe wrong) that 
you discuss Distros and Linux "Desktops". When we used to have CLUG 
meetings we often had "agendas" which included preplanned 
presentations which often enlightened me (I am not a geek, guru or 
programmer).


If you still do run such presentations then ignore this email but if 
you don't perhaps you and others could discuss the possibility and ask 
for presenters.


I would be happy to share my Linux journey and what I have achieved 
(with help from CLUG and Google).


I now have headless servers running MythTV, Emby, Transmission, Home 
Assistant, Virtual machines, ZoneMinder, NextCloud and WordPress and I 
am sure others could add to this list to offer other presentations.

Hi all, monthly notice, May 1.

Wednesday night is the GNU/Linux Users' workshop: 7.30pm-9.30pm in
the
South Learning Centre (SLC), through rear door of South Christchurch
Library at 66 Colombo Street, Cashmere -
https://my.christchurchcitylibraries.com/locations/SOUTH/ - held
on the
first Wednesday monthly, Feb-Dec.

LiveCD/DVD/thumbdrive installs of freenix* operating system
distributions are used to demonstrate alternative desktop
environments,
in the SLC computer lab of i5, all-in-one, touchscreen PCs.

Ubuntu-MATE is the Debian GNU/Linux variant we most display and Long
Term Support releases like 18.04 are recommended, though rolling
upgrades (19.04 is latest, April release) tend to run fastest with
very
latest kernel drivers and software incorporated. Both are up-to-date,
secure, and will run well on a lot of aged equipment to extend its
life.
See http://debian.org background and http://ubuntu-mate.org/download/
for these distros and http://distrowatch.com for a great many other
variants to choose from. Portable devices welcome, esp. laptops.

BYO distributions and any new tech you like; overhead projector - let
us know if you have a presentation to offer.

Thank you for the support of these workshops and the Software Freedom
Day annual installfest event.

Kind regards,

Rik Tindall
