Personally, I'd just use the post-up line.

Ideally whichever device is the DHCP server would set the appropriate 
MTU via its DHCP response, but if that's the phone, I have no idea how 
you'd fix that easily. (That's why there is a supersede setting for it, 
it can be part of the DHCP response — that's how different MTUs from 
different DHCP connections should work.)


Another option might be to use Network Manager, I think its connections 
can set a custom MTU, but I'm not 100% sure as I've never tried it.


BTW: dhclient.conf options can be per-interface (via an interface 
section), so your wifi and wired adapters could be different.

Either there's some IPv6 - IPv4 conversion involved, or Verison just
terminates inbound IPv6 connections on their end.

No. How IPv6 usually works is that you're given a /64 block of IPv6
addresses (whenever it's DHCPv6, RA or static configuration).
But you can clear things out easily.

Can you establish an outbound connection from the router via IPv6?
Something like this should do it:

curl https://ipv6.google.com

In my opnion skype uses your usb camera correct? and this may glitch with

Yes, many of the discussions I have seen of needing to lower MTU refer
to PPPoE.

I'm not that familiar with the internals, but basically, the phone
presents a wifi access point, the computer connects to it as it would to
any AP, and the phone apparently routes packets to and from the cellular
network.

Invisible IPv6 addresses

2019-12-17 Thread Celejar
Hi,

[Somewhat off-topic, since this is a general networking topic:]

I have Verizon Fios residential internet service. Verizon is
notoriously cagey about its deployment of IPv6 for residential service
[1], but I don't seem to officially have it - my router (running
OpenWrt) tries dhcp6 but fails to get anything, and all the router's
interfaces show only link-local addresses for IPv6.

I noticed, however, that when I try to connect to the router over the
public internet via a DDNS hostname tied to the router's external IPv4
address, the connections take place via IPv6! I dug (no pun intended) a
bit further, and found this (where a.b.c.d is my Verizon-assigned (via
dhcp) dotted-quad IPv4 address):

~$ host a.b.c.d
d.c.b.a.in-addr.arpa domain name pointer pool-a-b-c-d.region.fios.verizon.net.

(where 'region' is my geographic region).

~$ host pool-a-b-c-d.region.fios.verizon.net
pool-a-b-c-d.region.fios.verizon.net has address a.b.c.d
pool-a-b-c-d.region.fios.verizon.net has IPv6 address e:f:g:h:i:j:k:l

So lo and behold, I do seem to have an IPv6 address, and this address
e:f:g:h:i:j:k:l is indeed the one that my clients are using to reach
the router (xxx.yyy.zzz is the DDNS hostname):

~$ ping xxx.yyy.zzz
PING xxx.yyy.zzz(pool-a-b-c-d.region.fios.verizon.net (e:f:g:h:i:j:k:l)) 56 
data bytes
64 bytes from pool-a-b-c-d.region.fios.verizon.net (e:f:g:h:i:j:k:l): 
icmp_seq=1 ttl=51 time=29.1 ms

But the IPv6 address e:f:g:h:i:j:k:l is not actually configured
anywhere on the router (as shown by 'ip a' and other tools)! Is this
really how IP works, that since Verizon is sending packets with that
destination down my connection, my router is going to accept and reply
to them despite not having any such IP address configured?

inconsistent Clipit cut with firefox, konsole, claws

2019-12-17 Thread Wolfgang Rosner
Hello,

after upgrade from stretch to buster, my cut does not work as
before any more.

I run lxde, with clipboard manager Clipit 1.4.5
"using primary" and "syncing clipboards" is activated
(not sure about the english labels, since I run german locale)


Firefox:
I cannot copy web adresses anymore by just selecting them, as I did
before the update.
I can however copy adresses by using ctl+C
I can copy normal text from a webpage by just selecting it

Konsole (18.04.0):
sometimes I can copy text by just selecting it, sometimes I can't.

claws mail:
can't use bare X mouse clipboard any more, just CTL+C / CTL+V



Is there any point where I can finetune this behaviour?
Or at least understand it?
Could I use another clipboard manager within lxde?

I understand (sort of) why TLS is triggering the problem, but it's
fundamentally a PMTUD problem: on my normal network connection, with
the MTU left at the normal 1500, I have no problems. It's only while on
this particular connection via cell phone tether that I see problems.

It has to do with TLS.  Recent changes in the protocol have had the
result that it sometimes sends packets too large for the standard MTUs.
These packets cannot be fragmented, so you get intermittent problems
that seem like they must be at the other end.  I've had to reduce my MTU
to 1300.

Yes, I think this is pretty clear. The local wifi interface has the
standard MTU of 1500, so it rejects packets larger than that.

Yes, that's what's supposed to happen, according to everything I've
read, but overly aggressive blocking of ICMP is apparently a common
problem.

Not running one on the local machine, and I'm pretty sure that my
gateway firewall, an OpenWrt installation in a fairly standard
configuration, isn't configuring to do that (and don't
forget that I do get some "Frag needed" messages, as above).

Okay. Since the largest packets that get through consistently are
1440 bytes:

$ ping -M do 1.1.1.1 -s 1412
PING 1.1.1.1 (1.1.1.1) 1412(1440) bytes of data.
1420 bytes from 1.1.1.1: icmp_seq=1 ttl=55 time=103 ms

I tried (manually) setting the MTU to 1440. So far I have indeed seen
no further problems.

Now I just have have to figure out the best place to configure this.
I'm using dhcp via /etc/network/interfaces, but the 'dhcp' method
doesn't seem to support manual MTU setting. I could use a 'supersede
interface-mtu' line in dhclient.conf, but AFAICT, options there apply to
all dhcp connections, and I can't make out a simple way to set them on
a per connection basis. I suppose I could always just put 'ip link set
wlan0 mtu 1440' in a script and hook it in to the appropriate
'iface' stanza in e/n/i with a 'post-up' line.

Probablemente el entorno de root no es el correcto. Si haces login con

te recomiendo buscar un repositorio que ofrezca davinci resolve.

Por otro lado, la apuesta de Debian, en particular, es hacia la
estabilidad. Eso significa que no siempre estará en los repositorios de
debian los paquetes más actuales, pues estos deben pasar por un largo
proceso de control antes de ser integrados a la rama estable, lo cual hará
que algunas dependencias de davinci no puedan ser cumplidas por debian.
Ubuntu está basado en la rama inestable de Debian, es decir que tiene
paquetes más nuevos aunque no tan estables, por lo que podría ser un mejor
entorno para que puedas instalar Davinci sin problemas.


Problemas con PATH dpkg

2019-12-17 Thread Pablo Ramirez
Buenas Estimados

Mi nombre es Pablo y soy nuevo en el mundo de linux, el tema puntual es que 
estoy tratando de instalar un programa, en especifico DaVinci Resolve, pero al 
momento de ejecutar el comando dkpg salta el siguiente error:
dpkg: atención: `ldconfig' no se ha encontrado en el PATH o no es ejecutable
dpkg: atención: `start-stop-daemon' no se ha encontrado en el PATH o no es 
ejecutable
dpkg: error: no se ha encontrado 2 en el PATH o no es ejecutable
NOTA: El PATH de root debería incluir habitualmente /usr/local/sbin, /usr/sbin 
y /sbin.

buscando por internet, que es por donde estoy aprendiendo a usar linux,
no he logrado llegar a un solución, agradeciendo vuestra ayuda
de ante mano muchas gracias

instable X after upgrade to buster - X? firefox? liberoffice? screensaver? lxde?

2019-12-17 Thread Wolfgang Rosner
Hello, together,

after trapped into upgrade from stretch to buster, I get

(1) x server crashes after closing multiple libreOffice windows
(2) inacceptable response times after resuming from screen saver



Details for (1)

After crash, libreOffice restores open documents and opens them all
as stacked windows.
I repeatedly click on the "minimize" button to clean up my desktop, and
when I klick on the empty desktop after the last office window is gone,
X server session terminates immediately and drops to login screen.
I reproduced this three times.

I could NOT reproduce it by clicking on the empty desktop without
libreoffice restore cycle before



Details for (2)

After resuming from screen saver, response times to mouse and keyboard
event increases to several seconds.
It's even hard to work on a "Konsole"
Killing firefox (using system console) and maybe some other medium to
large applications alleviates the symptom.
Restarting firefox in the same session immediately slows down again.
I experienced similiar behaviour with lotus notes & wine.
After reboot, performance is normal again.
Feels like bad old WIN$ :-(((

I have a similiar behaviour with firefox 68 on my old laptop running
Windows7. So it might be related to firefox?

Top shows Xorg using ~ 103 % CPU (on a AMD 4300 quad core)
Mem is 16 GB and still ample free.

==


I don't know whether this problems are related.
I also can't pin it down to some specific package.
So I'll ask the list before filing a bug.

May workstation was set up with KDE in jessie.
Upgraded to stretch in early 2019 

Forgot to set apt sources to release, so I ran into buster last week
without having planned so.
Anyway, seamless upgrade between releases ist a debian promise, right?

currently using lxdm and lxde
I struggled with the known bug of X not starting after upgrade.
During fixing, I tried different display manager and desktops (Gnome,
KDE)

dual screen
 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800 GT]
 (rev a2)

lsmod: I think current driver is nouveau.
dpkg: xserver-xorg-video-nouveau1:1.0.16-1 


Anybody else with similiar experience?

Merci pour cette remarque, je vais donc aller un peu plus loin dans la

1) Code de conduite sur les ML :

2) Code de conduite de Debian :

Avec ce type de message envoyé sur la liste (notamment au travers du

faites, je vais en citer quelques unes :

** Code de conduite ML - Point 1 **
«  les listes de diffusion existent pour promouvoir le développement et

non constructifs ou hors sujet »

** Code de conduite ML - Point 11 **

** Code de conduite ML - Point 16 **

** Code de conduite Debian - Point 1 **
« Être respectueux »

-

Je vous invite à régler vos problèmes en privé, ou à défaut, tout
simplement à vous ignorer mutuellement.

Dans l'optique de ne pas lancer un fil de discussion inutile,
constructif et complètement hors sujet avec Debian, je cite le point 17
du Code de conduite des ML, « utilisez votre bon sens ».
Je vous invite donc tous à ne pas répondre aux présent message ainsi

Fair enough. (I do that between hosts using IPv6 over Cat5, and have

date version of the hosts file.


But does it need to? If your router runs a DNS server (you say it
does), it can provide that (DNS) service to the PC that's providing
the various other services.


Resolving hostnames via hosts file could be significantly faster than
using the router's DNS server.



It is, especially if the router is overloaded or switched off/rebooting 
;-) .



It's not one hosts file on every
machines on the network, it's one hosts file with every machines on
the LAN registered in it on one of the node on the LAN.


… which just means there are two machines needing the up-to-date hosts
file: the server-PC that avoids disturbing the router, and the router
running a DNS server. Still one more than necessary?


In the classic client-server topology the server doesn't need the
complete hosts file. Only the client(s) need(s) an entry for the server
in the(ir) hosts file[1].

Exception would be of course, if the service provided by the server
requires accessing other systems (backup server?).



You win the guessing contest, backup server with server initiated backups.


[1] This is probably known by most debian-user subscribers, I'm just
making sure we are talking about the same thing.

The only relevant script at boot-time on my system seems to be from alsa-utils.
But at the moment I'm lost how this interacts with pulseaudio.
At the same time the /pulse directory is created, there is created an also empty

Any idea, anybody?

Re: rsyslog adding old entries again

2019-12-17 Thread lists

Hi all,

I have now tried to use packetfence on CentOS, as they claim CentOS is 
their best supported platform. Now rsyslog logging works as expected:


- shutdown rsyslog
- delete files from the log directory
- start rsyslog
and only new/recent logs start appearing.

I have no idea why debian behaves as it does, but I'm happy to use 
centos for this particular install.


Thanks again for your answers.

Core dumps are instantly removed

2019-12-17 Thread Dmitry Katsubo
Dear Debian users,

Hopefully you can easily help me with my confusion.

I would like to collect / keep core dumps in the system. For that I use 
systemd-coredump package which is configured as following:

=== cut /etc/systemd/coredump.conf ===
[Coredump]
Storage=external
MaxUse=5G
=== cut ===

Then I have created a script to send core dump report daily to root:

=== cut /etc/cron.daily/coredump ===
YESTERDAY=`date --date="1 day ago" +%Y-%m-%d`
MESSAGE=`coredumpctl list --no-pager -r -S $YESTERDAY -U $(date +%Y-%m-%d) 2> 
/dev/null` && (echo "$MESSAGE"; echo -e "\nLast core dump info:\n"; coredumpctl 
info --no-pager; echo -e "\nCore
dumps:\n"; ls -l /var/lib/systemd/coredump; ) | mail -s "Core dumps created 
yesterday $YESTERDAY" root
=== cut ===

What I get is:

=== cut ===
TIMEPID   UID   GID SIG COREFILE  EXE
Tue 2019-12-10 11:27:26 CET2537  1003   100   5 missing

Last core dump info:

Core dumps:

=== cut ===

As one can see, stack trace is somehow captured by coredumpctl (where it gets 
it from?) but core file is not there. I would like core dump files to be 
preserved for (say) 10 days.

light-locker generates really tiny core dump when I start it from console:

=== cut ===
$ /usr/bin/light-locker
Trace/breakpoint trap (core dumped)

# ls -l /var/lib/systemd/coredump/
-rw-r-+ 1 root root 884992 Dec 13 14:16 
core.light-locker.1003.8103...157624301300.lz4
=== cut ===

Also I am aware about this setting:

=== cut /usr/lib/tmpfiles.d/systemd.conf ===
d /var/lib/systemd/coredump 0755 root root 3d
=== cut ===

but it configures the directory to be cleaned in three days while they are 
removed sooner.

Any ideas? Thanks in advance!

P.S. I have read:

https://wiki.debian.org/HowToGetABacktrace#Core_dump
https://wiki.archlinux.org/index.php/Core_dump

but didn't find the answer.

For the archives, the messages during the install are coming from the 
NEWS.Debian(.gz) files in /usr/share/doc//

One can check apt's or dpkg's log files for what packages have been 
upgraded and check all corresponding NEWS.Debian files.

Kind regards,
Andrei

Resolving hostnames via hosts file could be significantly faster than 
using the router's DNS server.

In the classic client-server topology the server doesn't need the 
complete hosts file. Only the client(s) need(s) an entry for the server 
in the(ir) hosts file[1].

Exception would be of course, if the service provided by the server 
requires accessing other systems (backup server?).

[1] This is probably known by most debian-user subscribers, I'm just 
making sure we are talking about the same thing.

Kind regards,
Andrei
