Debian Configuration :: Can't Receive System Messages
Mar 2, 2010
I have a small LAN. I am in the process of installing a Debian Lenny/Squeeze system into the LAN. I want to send and receive system messages using rwalld and wall.I can send a system message from my Debian system to another box using rwall. I can send a local message within the Debian box using wall in a console.I cannot send a local message using wall Konsole in KDE 3.5.x. The KDE Write daemon fails to provide any pop-up window./usr/bin/wall is installed from the bsdutils package and is set to -rwxr-sr-x.
The ktalkd package is installed. The KDE control center shows a configuration option in Internet & Network settings called Local Network Chat.When not in X, mesg is set to y at the console. After starting KDE and I open Konsole, mesg is always set to n. I don't know how this setting toggles. Further, setting mesg to y in Konsole has no effect on getting wall to work.mesg is set to y when I run xterm in KDE. Then wall works within that terminal window. However, the KDE Write daemon does not see the message in xterm.When I send a message from another system to the Debian system using rwall, xterm receives the message but not Konsole or the KDE Write daemon.

I have a C program which does.
1. Creates a UDP socket
2. Send the UDP Request packet to the TFTP server.
3. If the TFTP server is not listening in the 69 port, the remote machine send an ICMP ("Port Unreachable") message.
Is there a way to receive a notification from the Linux kernel on receipt of an ICMP packet to the created UDP socket.

An issue that has been hassling me for years since I started using Linux (Debian!) is related to the boot messages that quickly scroll on the video during the boot process. The main hassle is related to the fact that I cannot get a log of those messages. The second hassle is due to the fact that with my brand new netbook (Toshiba NB200) I cannot even stop the scroll and go back along the message stream with SHIFT+PageUpDown to understand what's going on. Of course I know that I can get a log of the boot process with 'dmesg' but I get the feeling that the very first lines show some problem I cannot grab at all.

Just another newbie question here, I've recently changed my main OS to ubuntu 9.10 and everything is going swimmingly.Except a small problem with empathy IM. I have seen posts where people complain about it not being able to set its status to hidden for MSN, this is not what my problem is.My problem is as follows: when friends of mine who's status is set to hidden on MSN (them using windows and default MSN app) message me, I receive no such messages. They have to set the status to visable to be able to message me at all.
On XP I used Digsby, it could recieve such messages normally. So I am not sure if it is due to empathy being a 3rd party app.

// Definition of the Socket class
#ifndef SOCKET_H
#define SOCKET_H
#include <sys/types.h>
code....
I've made a client just for test it, but no ones run well, the server is always returning -1 when accept is called!!

I'm trying to stop all boot time messages from appearing -- basically I'd like to have a simple blank screen from grub to xdm.
I tried everything -- used the "quiet" option in grub's config, added dmesg -n 1 to rc.local, changed console=ttySx, set kernel.printk in sysctl.conf to 4 1 1 7, and even eradicated rsyslogd altogether... to no avail. I still see all sorts of messages on my screen.

The system crontab (/etc/crontab) uses the same format, except that the username for the command is specified after the time and date fields and before the command.
[code]...
Every hour, I get an e-mail complaining about the first line of the crontab:
[code]...
I get the same complaint from the other entries: It looks to me as if cron, or anacron, is trying to execute the user (root) as a command. Predictably, the shell doesn't like it, so barfs and triggers an e-mail about it. Why is this not doing what the man page says it should do? The 2nd problem I believe is related to exim, not cron. The e-mails I'm getting above are being bounced from my ISP because they are directed to root@myisp.com, rather than my regular e-mail address. When the message bounces, it bounces to my regular e-mail address. In /etc/aliases, I have root: [URL]... and in etc/email-addresses I have root: [URL]... Adding the entry to /etc/email-addresses allowed the bounce to find me because the sender's address is [URL]... but how can I get cron to send these messages to me in the first place, instead of root?

Installed 6.01a from DVD 1 on a system with 4GB ram. Installer installed amd64 version by default. When I try to install amd64.deb files I get "wrong architecture" error messages from the package manager.
root@Laptop-RalphDeb:/home/ralphq# uname -r
2.6.32-5-amd64
root@Laptop-RalphDeb:/home/ralphq# uname -p
unknown
Why I can install amd64 programs and why I get unknown for the uname -p command?

I've got a Shorewall (Shoreline?) firewall up and running, but it's logging to /var/log/messages. I'd much rather have it logging to another location e.g. /var/log/firewall but can't find (a clear enough) explanation on how to do this. Apparently, it varies greatly depending on the distro, the kernel, and the version of Shorewall that is running. You'd think it would be something as simple as setting a path in a config file, but apparently not. I'm running a stock Lenny kernel on the firewall machine. It comes with version 4.0.15 of Shorewall.

I am using Squessze and Gnome. When I try to use the gui System>Administration>Network or Users and Groups I get the error The configuration could not be loaded. You are not allowed to access the system configuration.Everything was working before. I read around a bit. In some cases,it was caused by mismatching group and password files after using the gui. I do not know how to check if they are matching. Of course I do not know for sure that is the problem in my case.

How does the 'testing' version of Debian stabilize? I mean, the updates from upstream are very frequent, so if the Debian maintainers upgrade a package till the very end (for e.g if they just upgrade to 2.6.36), when will they get time to test it (so as to freeze it)?

I have some simple practical requirement to receive a mail if someone logged to my system.
I think we can see who are logged into our system using the command who or finger or w.
But I want to get a mail as soon as a guy logged into my system.

I would like to remove a specific domU (test01--pv--guest) from my machine. I am not sure how far/to what extent to remove files. Here are the files and properties it seems I should remove:
lrwxrwxrwx 1 root root 10 Jan 9 11:05 /dev/disk/by-id/dm-name-xenvg-test01--pv--guest--disk -> ../../dm-3
lrwxrwxrwx 1 root root 10 Jan 9 01:03 /dev/disk/by-id/dm-name-xenvg-test01--pv--guest--swap -> ../../dm-2
lrwxrwxrwx 1 root root 7 Jan 9 11:05 /dev/mapper/xenvg-test01--pv--guest--disk -> ../dm-3
lrwxrwxrwx 1 root root 7 Jan 9 01:03 /dev/mapper/xenvg-test01--pv--guest--swap -> ../dm-2
lrwxrwxrwx 1 root root 7 Jan 9 11:05 /dev/xenvg/test01-pv-guest-disk -> ../dm-3
The above link to dm-2 and dm-3.
brw-rw---- 1 root disk 254, 0 Jan 9 01:03 /dev/dm-0
brw-rw---- 1 root disk 254, 1 Jan 9 01:03 /dev/dm-1
brw-rw---- 1 root disk 254, 2 Jan 9 01:03 /dev/dm-2
brw-rw---- 1 root disk 254, 3 Jan 9 11:05 /dev/dm-3
brw-rw---- 1 root disk 254, 4 Jan 9 01:03 /dev/dm-4
brw-rw---- 1 root disk 254, 5 Jan 9 01:03 /dev/dm-5
brw-rw---- 1 root disk 254, 6 Jan 9 01:03 /dev/dm-6
brw-rw---- 1 root disk 254, 7 Jan 9 01:03 /dev/dm-7
Will they be deleted automatically or should/can I remove them? How do I check the need for the other dm-? files? As indicated below, it seems like some may be duplicates.
I also found this set in /etc/lvm/archive/:
-rw------- 1 root root 2909 Oct 17 00:41 Relaise-vg_00000-1453251236.vg
-rw------- 1 root root 2929 Oct 24 22:08 Relaise-vg_00001-1530642081.vg
-rw------- 1 root root 2924 Oct 25 19:33 Relaise-vg_00002-328450675.vg
-rw------- 1 root root 2901 Oct 26 19:53 Relaise-vg_00003-1555350964.vg
-rw------- 1 root root 2902 Oct 26 19:53 Relaise-vg_00004-1044927704.vg
[Code] ....
Some of these seem like duplicates. This may be due to multiple attempts to build the volumes. Is there a way to determine if all of the are useful?

If I shutdown from X the system hangs and I have to yank out the power cord. Same on logout.
ctrl+alt+f1 hangs for a few minutes and then starts a terminal; which does not respond to the keyboard.
There are no tty.conf files in /etc/init .
But inittab looks normal to me and includes tty (1-6)
Executing init 6 from a terminal in X will reboot the system
I was thinking this might be a dbus issue, but I am not sure. I also understand some recent issues exist with SysRq sequences. May be a video card issue,,,
Other than normal package upgrades the only changes were a recent change from a VGA to HDMI cable. I can't see why that would matter

I was wondering if a standard Debian 8 system with Gnome desktop does any kind of local dns caching, and if so, what the command is for clearing it. (Assuming I haven't purposely installed any DNS server software.)
I found multiple posts on the Web about unix DNS caching, but with widely different answers across distributions and across time.

I am running Debian on an ARM module (BananaPi).5 minutes ago, i started upgrading the system, but fortunately the power cable moved and the system closed.Now i open it up again and i'm trying to re-upgrade the system but i'm always getting this message
# apt-get upgrade
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

I have installed jessie on a couple of machines. One is configured as the NFS filesystem exporter and NIS server. The other one, I am trying to configure as NFS and NIS client. NFS does not seem too much of a problem, I can mount the exported filesystem to a directory in the client and unmount it, but when I install NIS the system becomes very slow. Any command preceded by "sudo" takes a very long time (a few minutes) to complete. Then, upon rebooting the system, it reports many services failed to start (login, accounts, modem manager, avahi, network manager, exim). When if finally completes, I get a terminal login, instead the graphic login window.

I updated squeeze last night for the first time. It worked fine after 1st reboot last night. There was one reboot stalled at "hald" so I shut down and restarted. Worked ok 2nd time around
Today,upon login I got a string of taskbar notification (which I couldnt read as they all overlapped . I was able to see a kernel error message but couldnt report it (network was down) or save it (USB stick not recognised) Some programs worked, others didnt
I have the partedmagic rescue distro on USB stick so have those programs to use in order to fix the problem. Any idea how I can repair this? I tried fdisk for the hell of it. reported clean partition as predicted. I am using debian-testing-amd64-kde.

I have a Dell Latitude E6410 which I can boot from an Iomega external hard drive when I want to run Linux on it. It is a work issued Windows XP laptop and when I travel, I am more comfortable with Linux, so I created a dual boot option without touching their hardware. The external hard drive plugs in to the USB ports and the BIOS picks it up as the primary boot media, although the internal drive is still present. (That is the desired outcome).The problem is that the system periodically locks up solid and only a forced power off will get it to respond. The system seems to go into a kernel panic and fails to write anything before dying. The system completely locks up and stops responding to mouse and keyboard. It also seems to drop off the network. When I look at the logs after restarting, nothing at all shows up related to a kernel panic or anything else. To further complicate the diagnosis, on the reboots, sometimes the boot process locks up at "Starting GDM3", sometimes it doesn't, and wont for several attempts but eventually will boot to gnome. Some times it runs fine for a few hours, sometimes for only a few minutes. Can anyone recommend a way to diagnose this?I am trying to run Debian 6.0 32-bit with the defaults.
