Re: Montar HD externo

[Ricardo Ramos]

O HD é novo? Já usou ele alguma vez? Se usar ele no Windows ele abre
normal?

Se a resposta pra essas perguntas for "não", então formata o HD, aconselho
a usar o Gparted, criar uma nova tabela de partições e criar uma nova
partição NTFS.

Caso tenha alguns dados no HD, mente no Windows, faça o backup e depois
proceda a formatação. O filesystem reconhecido não é um NTFS, pode ter
alguma coisa de errado com ele, e outra, no HD principal do PC VC também te
esse filesystem, a máquina tem dual noite?

Pergunto porque nunca vi esse filesystem (Microsoft Basic data) antes.

There are probably better ways.  I pulled the ideas for the following
from the Web.

I put the following in ~/.bash_profile:

--8<

# ~/.bash_profile

if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi

# Start keychain for sessionwide access
export SSH_ASKPASS=/usr/bin/ssh-askpass-fullscreen
eval $(keychain --eval id_abcd id_defg id_hijk id_lmno id_pqrs)

->8-

The relevant packages I installed were:

ssh-askpass-gnome
ssh-askpass-fullscreen

If I log into a virtual console first then I am prompted for my
specified SSH keys before I get a Bash prompt.  Likewise, when I log
into Xfce (or any desktop from a graphical login manager) then a full
screen prompt appears for the passwords before the desktop loads.

As for GPG, I don't use an agent.

HTH,

Re: determining subnet mask using ip but not using ifconfig in debian 9.0 (stretch)

[Dan Hitt]

Thanks Marc, so indeed it does (and i guess 'ip -4 addr' or 'ip -4 a'
would work fine for me).

(Aside from google, i did a search for 'mask' in the ip man page and
didn't see anything, but your command sure settles the issue.)

determining subnet mask using ip but not using ifconfig in debian 9.0 (stretch)

[Dan Hitt]

What is the preferred way to determine the subnet mask of your box
using /bin/ip on debian 9.0 (stretch)?

In the old days, this sort of information would come out of ifconfig,
but it looks like debian really wants to get away from ifconfig, and i
think use ip as a sort of replacement.

So i would like to do the same thing, using ip or whatever the debian
people think is the best practice.

I tried to search for this information using google, but not very skillfully.

TIA for any info.

here.



- https://xmodulo.com/spoof-mac-address-network-interface-linux.html


I know how to spoof a mac address temporarily and permanently, that's 
not what I'm trying to do.



- Modern Linux distributions like Ubuntu typically use Network
Manager, which provides a graphical way to spoof a MAC address. For
example, on Ubuntu you’d click the network icon on the top panel,
click Edit Connections, select the network connection you want to
modify, and click Edit. On the Ethernet tab, you’d enter a new MAC
address under “Cloned MAC address” and save your changes.


Network Manager is broken when it comes to mac address spoofing, I'm too 
tired right too go and find the bugs back there are/were a series of bug 
about the fact that Network Manager won't honor mac address passed to it 
through the GUI or simply won't let the mac address being changed.


IIRC, the devs didn't see the point of fixing that behavior and that's 
why 90% of the articles you can find about "how to spoof the mac address 
via a GUI" discourage the use of network manager and the reason why it's 
not used in tails [1].

And while we are stuck in Prehistory with network manager on our 
desktops, iOS (a fucking mobile operating system) randomizes the mac 
address of the device even for scanning [2].

Why not make your own top level directory, i.e. /ric (with Documents and 
such)--that's what I do.

Same comment as above--why not make your own top level directory for that 
stuff.  (Reading the File Hierarchy Standard (FHS), I don't think that is quite 
the intent of /usr/local--and could make some things inconvenient at one time 
or another...)

Skype on Linux is terrible and crashes randomly, even after fixing the

market leader in VOIP; this is especially common in a business environment.

Skype needs to run on Linux with the same stability that it does on
Windows and MacOS, WITHOUT resorting to installing WINE, and preferably
without relying on WebRTC.

If you could develop a non-Skype Linux client with the ability to easily
communicate on the Skype platform --- something open source but which
has compatibility with Skype, coordinated with Microsoft --- that would
be ideal. But relying on Microsoft to develop good software for Linux
has proven to be a losing proposition and I'm sure is stifling the
adoption of Linux by a wider audience.

Having frequent connection drop-outs with Skype on different Linux and

better, buy still not as good as I'd like.  Now I'm trying to migrate

Bug report: after booting, if laptop lid is closed without login in, the computer doesn't go to sleep

[commentsabout]

Hello,

I am a Debian 8.7 user (with Gnome 3.14.1).
On a Thinkpad X220.

I do not know where this bug would be best reported so I will let people 
with more knowledge than me about these sort of things fill a bug in the 
proper place.



# laptop lid closure not taken into account

When I start my computer and reach the login screen, if I close my 
laptop lid, the computer won't go to sleep mode *.


It goes actually beyond that.

If I login but don't open any application (such as the file explorer or 
firefox or whatever) and close the laptop lid, the computer won't go to 
sleep mode *.


* until I either login and open an application or just open an 
application depending on the case.

from the menu


This bug migh be related so I will leave it here as well.

If click on the top right menu on my desktop (the one withe the wifi 
indicator etc), click on the "power button" icon and then chose "cancel" 
in the dialog box, I can not shut the computer again via this menu until 
next reboot/logout-and-in, the only way to shut the computer down is to:



shutdown now


Hope this is helpful and will be reported to the right people/place.

Re: Montar HD externo

[Rodolfo]

Olá, consegui perceber na saída do fdisk -l um disco denominado /dev/sdb,
seu HD externo tem 1 TB?

Tente esse comando como root:

# mount -t ntfs /dev/sdb1 /mnt

Você pode substituir o /mnt por outro diretório, faça esse teste e depois
tente acessar o caminho da montagem.


Abraços.

Automatically spoof MAC address when interface is brought down

[commentsabout]

Hello,

I am a Debian 8.7 user.
I use the default Network Manager.

I would like to know if there is a way to automatically spoof the MAC 
address of my wireless interface every time I bring down (and up)?


I have a Thinkpad x210 and there is a physical switch for the wifi 
interface. For the time being, every time I close my laptop lid and open 
it up again, I have to manually:



su
macchanger -a wlan0
exit


Is there a way to automate this?

Thank you in advance for your help.

Keys management (SSH, GPG)

[commentsabout]

Hello,

I am a Debian 8.7 user.


# SSH

I would like to know if there is an efficient way to manage SSH keys?

I have multiple SSH keys (rsa, ed25519) that I use all day long to 
either connect to servers via ssh or to work with on remote servers.


I would like to know if there it is possible to unlock my keys (being 
prompted once for their passwords) when the my session starts and keep 
them unlocked until the session is closed.


I have found information about ssh-agent and ssh-add but it doesn't 
provide the behavior that I would like to reach in the sense that I have 
to manually...



eval `ssh-agent -s`
ssh-add /path/to/my-key1
ssh-add /path/to/my-key2
ssh-add /path/to/my-key3
ssh-add /path/to/my-key4


... every time I open/close my session (while I would like to just have 
to provide my passwords). Furthermore, it seems that my ed25519 keys do 
not remain cached for more than a couple of minutes (while the rsa4096 
ones remain without problem).



# GPG/PGP

This list is probably not the right place to ask but I will give it a 
shot.


The question is quite the same for PGP/GPG. I use GPG/PGP extensively 
via Thunderbird and its Enigmail extension. There are known issues 
between Gnome Keyring and gpg-agent [1]. I would like to achieve what is 
described above for SSH, namely being prompted once per session for my 
GPG (whatever key) password and that's it.


I also extensively use the "pass" command-line tool (GPG based, password 
manager- awesome!) which prompts me for my password every now and then. 
A cached unlocked GPG key would be tremendously useful here too.

You cloned a mess, you got a perfect copy. I'd do a clean install to
the new drive, after formatting the entire drive. Once you boot into
that drive, mount the old drive. It should show up in 
/media/

Then copy the directories of personal stuff you want to keep to a new
location on the new drive. I use cp -raf 
 and everything, including sub-directories, file
ownership and file permissions are preserved. If a file is clunky, it
won't copy it and should proceed.

Next, if you are in your office, observe if the window is open. If
yes, throw the old drive out of it. :) Ric



Ric,


As soon as I finished my last post (above) I realized that what you
suggest is exactly what I should have done in the first place. Why I
did not realize that earlier (and save myself a lot of headaches) I do
not know.  The system is now booting to the old drive, just as it did
before.  I think it just needed a good night's sleep.  I know that I 
did.


My next steps are:

Format new drive

Install fresh on new drive

Mount and copy /home from old drive to new drive


Careful there, I would not copy any of the /home/username/dot-files 
or dot directories over, except like .mozilla and .thunderbird, so 
you don't carry over some old and crufty setting that might have been 
problematic. To spare you nightmares like this one, I use the /opt 
directory on a separate partition for all of my personal data.
So, I use /opt/ric/Documents and in my brand-new /home/ric directory 
I delete the newly created Documents directory and then link (ln -s 
/opt/ric/Documents Documents) and do the same with the other familiar 
home directories like Videos, Music, Downloads, everything except 
Desktop. If something goes ape, systemk-wise, you can do a fresh 
install of / (root) directory and leave /opt alone. I've done this 
since the old Caldera days. Nary a burp in the barrel! Ric




I don't usually go quite that far, but photos, videos, and virtual 
disks are all in /usr/local/  which I will also need to copy over.  
You say to avoid copying   except .mozilla and .thunderbird.  I have 
117 such dot-files and dot-directories.  Are you saying only to leave 
.mozilla and .thunderbird and have everything else rebuild when it is 
next used.  Admittedly, that will get rid of some cruft, but how 
should I determine if there are others that I should keep?



I tried to format the new drive using st (Seagate Tools).  It said 
that it would remove all data, which is expected, but nothing was 
removed!  It also took less than a minute.  Should I be using /dev/sda 
in the command line instead of /dev/sg0 (which is how st -l lists the 
drive)?
I just tried this with 'st -i /dev/sda' (which should give drive info) 
and it does nothing, so that doesn't work.  So how do I lay down a low 
level format on this drive?

Great! That worked! It seems that the only value specified in
LimitNOFILE applies to both the soft and hard limit.

Petició de consell - Processament de correus "en massa"

[Orestes Mas]

Benvolgudes,

A l'escola del nano volen fer un llibre amb fotos per final de primària.
A tal efecte s'ha demanat a totes les famílies que envïin correus amb
fotografies adjuntes a una bústia creada a tal efecte, la qual és
accessible via IMAP.

Com que són força correus, m'agradaria programar/utilitzar algun
procediment automàtic que anés recorrent la llista de correus rebuts i
desant els adjunts en carpetes diferents (amb el nom del remitent, per
exemple).

Vosaltres com ho faríeu? Coneixeu alguna eina / procediment que pugui
fer això mateix, ja sigui directament o amb una mica de configuració prèvia?

En cas que no hi hagi més remei que programar-ho, què empraríeu? Scripts
de bash? Python (amb quines biblioteques)? Perl? Altres? Haig de dir que
amb el Python o el bash encara em veig en cor de posar-hi mà, però amb
la resta hauria de ser una solució bastant tancada perquè no en sé un
borrall i el temps que em portaria ficar-m'hi no compensa l'esforç de
processar els missatges a mà.

Gràcies de bestreta.

Orestes.

No, the dependency is on 'libbluetooth3' for Stretch version of
network-manager (1.6.0-1). No dependencies are shown for previous
versions.

Mmh, I started to feel lost when the 'route -n' showed no connection and
'ifup eth0' said 'unknown device' or something like that. 
Then I found older version 1.4.4-1, which is probably Jesiie's.

If this is a private package which you are using to enforce your local
configuration, just change the conffile in your postinst [possibly after
checking that the conffile hasn't been modified.]

If this is a package which you are planning on having anyone else use,
then you basically shouldn't be touching /etc/ssh/ssh_config or
/etc/ssh/sshd_config, because you're likely to break things horribly.

Het klinkt als onbelangrijke foutmeldingen die weinig kwaad kunnen, maar
wellicht storend zijn omdat het er niet zo mooi uit ziet.

Misschien kun je vertellen welke modules niet willen laden?

Systemd haalt de modules hier vandaan:
/etc/modules-load.d/*.conf
/run/modules-load.d/*.conf
/usr/lib/modules-load.d/*.conf

Als ze nergens staan, dan helpt het heel misschien om de modules te
blacklisten. Ik doe dat door een .conf-bestandje te maken in
/etc/modprobe.d/ . Met een inhoud zoals dit:
--
# usb video displaylink
blacklist udlfb
--
Maar eigenlijk lijkt me dat het om modules moet gaan die in
bovengenoemde mappen staan.

Groeten,
Paul

Juanjo, muchas gracias.
Se solucionó añadiendo en ~/.profiles esa línea.
Pero para que sea válido para todos los usuarios del sistema,
modifiqué el archivo de arranque de Chromium en
/usr/share/applications/chromium.desktop

Ahora que tengo la punta del ovillo, veo como hacer una solución más

Maar ik begrijp het niet.
Mijn inschatting is dat er gemeldt wordt "Werkt, nog het laatste loodje".

Deze e-mail is om te vragen: "Heb je inderdaad een werkend system?"
Of is 'Failed to start Load Kernel Modules' toch "fataal"?

Dat om in te schatten welke prioriteit de vraag met krijgen.

True, but my reply was to someone worried about lacking Internet
access at home, who said:

One has to bear in mind that apt asks a lot of questions with
(a) a default answer and (b) no clearing of the type-ahead buffer.
So there may be people who live one keystroke away from accidentally
clearing their cache at times.

This is a case of the perfect memory versus the contents of cups'
postinst script. The "perfect memory" is accessible to only one
person; the postinst script is accessible to everyone. All the
somebodies (that could be the OP if he feels inclined to other than
speculation and ad hominem) could examine it and point out where it
replaces 'Listen localhost:631' with something else.

Not that it is important in the grand scheme of things, but having
a technical detail or two wouldn't break the bank.

NetworkManager depends on bluetooth because it can configure network via
bluetooth devices such as mobile phone, where you can use the phone as a
modem.

I don't see dependency between network-manager and bluetooth in jessie

$ apt-cache show network-manager

Please confirm that you wiped the 1 TB recovery drive.

I tried to boot to the old disk (since it was still wired that way).  I got

physical volume for all my LVM logical volumes -- /usr, /var, /home and
/temp.  It says to run fsck manually.

I decided to try the new drive, so I changed the cables and re-booted.

Maintenance shell, again.

lvm started

/home fs has errors run fsck (at this point, I'm afraid to try it)

You can also generate override files for dynamically generated units by
creating /etc/systemd/system/jitsi-videobridge.service.d/configname.conf

"configname" can be whatever you want.

In this file you then put

,
| [Service]
| LimitNOFILE=65536
`

and do a "systemctl daemon-reload".

If you now "systemctl cat jitsi-videobridge.service" you should get the
output of the generated file and your appended override config.

Stretch and Jessie this week. Am in Jessie this second... no new
updates needed for days AND/BUT... five minutes ago, a website
complained that my browser is out of date = here's your sign. :)

Dear team,

The hard freeze of Debian Stretch has now started. It is time to start
thinking about the coverave (sic) of the release of Stretch and communication
during the freeze.

We would like to invite all interested people to fill in very soon the
following poll to find a time slot to hold a team meeting before the end
of next week.

https://dudle.inf.tu-dresden.de/ti5hm7p9/

Times indicated are UTC.
The selection of time slots is a bit arbitrary. I hope we can find one
which could be convenient for most people. Feel free to add time slots
if you feel the need to.

If you always wanted to help the publicity team, but didn't
know how, here is a chance :)

Best wishes,

Cédric

Very interesting. Thanks for the reference! I see that in this case the
directive to use is LimitNOFILE=. Although I did not find the
syntax (for example, LimitNOFILE=soft:hard).

In this case, it seems that the service file for systemd is created

Issues with power management

[solitone]

Hi, I resend this message because in my previous attempt I mistakenly linked 
it to a completely unrelated thread. Sorry for the inconvenience.

as I told in thread "Monitor switched off after resume from hibernation", my 
MacBookPro 12,1 had problems with hibernation in stretch. If hibernation 
happened after the monitor had been switched off, the system would not turn 
the monitor on again after resume. Therefore I disabled hibernation.

With time, though, I noticed that even suspension doesn't work very well. 
Sometimes the laptop does not suspend, neither if I wait for the set 5 
minutes, nor if I close the lid. It basically remains active, cunsuming 
battery.

So today I tried to re-enable hibernation, and discovered that now it does not 
work at all. Perhaps it was a recent stretch update, but now hibernation can't 
be used at all. Previously it worked at least when the monitor was on. Now 
even when the monitor is on and I hibernate, when the system resumes I don't 
get a usable session. I just get an emtpy black screen with the white cursor 
on it, but nothing happens. I can't even switch to a virtual console with crtl
+alt+F. 

What do you suggest to do to investigate this issue? A functional power 
management is a must on a portable computer.

Thanks!

I believe the correct approach is to add one of the limit= directives
to the systemd unit.  See systemd.exec(5) for details.  Searching for
the word "limit" gets you to the correct section.

I had thought that I could add something to the script that starts the
process, but I'm not sure if it's the best idea from the point of view
of maintainability because a package update could eliminate that change.

Another alternative might be to add something like this to /etc/rc.local:

---
PID_JVB=`ps -u jvb | tail -1 | awk '{ print $1 }'`
prlimit --pid $PID_JVB --nofile=10240:10240
---

But perhaps there is another more elegant way to achieve this.


Thanks for your reply.

Yes, if the process is being started via a shell, ulimit seems the
way to go. In SysV init, either in the start script or perhaps in
/etc/defaults (which is then picked up by the start script).

Note that /etc is "taboo" for the distro[1], i.e. it will install
something there, but in won't touch anything which wasn't installed
by the distro, at least not without asking.

Sure systemd has a way to do that, but for that I'll have to defer
to the systemd experts.

[1] at least for civilised distros, like Debian.

Best way to set maximum number of open descriptors for a process

[Daniel Bareiro]

Hi!

I would like to set the maximum number of open descriptors for a
specific process in a way that is maintainable.

I've tried putting something like this in /etc/security/limits.d/:

jvbsoftnofile   10240
jvbhardnofile   10240

But this seems to only apply to processes with an active shell in the
system:


root@conference:~# cat /etc/security/limits.d/jitsi-meet.conf
jvb softnofile  10240
jvb hardnofile  10240

root@conference:~# ps -u jvb | tail -1 | awk '{ print $1 }'
434

root@conference:~# cat /proc/434/limits | grep open
Max open files4096 4096 files

root@conference:~# su - jvb
jvb@conference:~$ ulimit -n
10240


Maybe I could add something to the startup script, but maybe if the
Debian package is updated, these changes will be lost. What do you
suggest is the best way?


Thanks in advance.

Kind regards,
Daniel

Re: Synaptic Error: Duplicates in sources.list

Which directory? /var/lib/apt/lists? That won't help. You need to fix 
the source, i.e. duplicate lines in the sources.list file in /etc/apt/ 
or - possibly - duplicate files/entries in /etc/apt/sources.list.d/.

Synaptic Error: Duplicates in sources.list

[Klaus Jantzen]

Hello,

I am still running Wheezy.

When using Synaptic to upgrade Wheezy the following message is issued:

=
W:Duplicate sources.list entry ..
(/var/lib/apy/lists/security.debian.org_dists_wheezy_updates_main_binary-amd64_Packages
W:Duplicate sources.list entry ..
(/var/lib/apy/lists/security.debian.org_dists_wheezy_updates_main_binary-i386_Packages
==

I removed the two entries in the directory but with the next start of
Synaptic the error appears again.

What do I have to do to remove these entries permanently?

Thanks.

I am currently testing Jitsi Meet [1] with Debian. Here [2] you can see
a server with Jitsi Meet open to the community for test the system.

Issues with power management

[solitone]

Hi,

as I told in thread "Monitor switched off after resume from hibernation", my 
MacBookPro 12,1 had problems with hibernation in stretch. If hibernation 
happened after the monitor had been switched off, the system would not turn 
the monitor on again after resume. Therefore I disabled hibernation.

With time, though, I noticed that even suspension doesn't work very well. 
Sometimes the laptop does not suspend, neither if I wait for the set 5 
minutes, nor if I close the lid. It basically remains active, cunsuming 
battery.

So today I tried to re-enable hibernation, and discovered that now it does not 
work at all. Perhaps it was a recent stretch update, but now hibernation can't 
be used at all. Previously it worked at least when the monitor was on. Now 
even when the monitor is on and I hibernate, when the system resumes I don't 
get a usable session. I just get an emtpy black screen with the white cursor 
on it, but nothing happens. I can't even switch to a virtual console with crtl
+alt+F. 

What do you suggest to do to investigate this issue? A functional power 
management is a must on a portable computer.

Thanks!

Argh.  Indeed, a boot hang could/would happen should you get exec
failures on the ORDER files that are *inside* the initramfs, i.e. if the
file reported as not being executable was something like this:

/var/tmp/mkinitramfs_/scripts/local-block/ORDER

(and yes, it is /var/tmp and not /tmp as I said...  My recollection of
this very obscure issue was slightly corrupted by time :-( )

I failed to notice the path on the ORDER files it was reporting as not
being able to execute, I apologize for that.
