Ubuntu Networking :: Disable ICMP Router Discovery For IPv6?
Jan 14, 2010I set up a static IPv6 address and a gateway in /etc/network/interfaces. However, a bad router in my network environment alway send wrong ICMP router discovery messages to me. So I have got extra (wrong) IPv6 address and gateway, and the routing is confused. On Windows Servers, I can use "netsh interface ipv6 set interface "Local Area Connection" routerdiscovery=disable" to disable ICMP router discovery. But I don't know how to disable it on Ubuntu 9.10. How could I disable ICMP router discovery for IPv6?

Sep 5, 2011I am using Arch Linux and want to disable console messages which are displayed when the kernel boots. I have tried the quiet and loglevel=2 options in /boot/grub/menu.1st as given below:
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/c6dbfcdc-fcd8-498e-9182-f3bddc4f05ff ro loglevel=2
However I am still seeing console messages at boot. I used grub-install after the changes.
Any ideas where I am going wrong?
Ubuntu Security :: UFW Block ICMP When Add Non ICMP Related Rule
May 21, 2011I am setting up a virtual server. Ubuntu 11.04, "minimal provider image".UFW was disabled by default. I set it to default deny. Allowed HTTP, SSH and other standard stuff, and enabled it. All seems to be OK. Adding one rule to block some annoying security scanners causes ping not to work. I'm not an Iptables expert, but it looks OK to me. I got it from some website, rather than invented it myself, but modified to to fit the ufw config file syntax. What in that rule prevents pings?!? It seems completely unrelated.

OpenSUSE Network :: When Disable Firewall / Delayed Messages Can Again Be Sent
Sep 14, 2011I have been running Senmail on SuSE 11.1 for the last few years with no problems.Since installing SuSE 11.3 a few months ago I have been having problems getting Sendmail to send to some (only a few) servers.If I disable the firewall # SuSEFirewall2 stop.I can send successfully using # sendmail -v -q, or # sendmail -v -qIxxxxx.When I re-enable the firewall I will start to get the timeouts/temporarily unavailable messages again (but as mentioned above, only for some servers) even though I can successfully telnet these servers when the firewall is on. When I disable the firewall the delayed messages can again be sent.Has anybody any ideas what I need to change (presumably in the Firewall) to get things working correctly? 'SMTP with sendmail' is already selected under 'Services to Allow' under YaST Firewall->Allowed Services..
View 4 Replies View RelatedUbuntu :: How To Hide Or Disable Messages During Start-up And Logout In 9.10
Jun 16, 2010I am building a live USB key using Ubuntu 9.10 Karmic. No upgrades have been applied. It is as it came in the ISO that was distributed.I would like to create a smooth start-up/logout process where no messages pop up (even briefly) that might confuse someone who is not very tech savvy. I'm referring to the messages that show up right before the login screen during start-up (between usplash and xsplash I think) that say:
"Starting early crypto disks ..."
and also the messages that show up on a black screen right after you initiate logout. It seems to sometimes show system messages including some error messages that can confuse users.Does anyone know of a way to hide, redirect, or disable these messages? I just don't want cryptic messages popping up even briefly that are going to confuse casual users. I'm stuck with version 9.10 since I've made some custom mods and would rather not redo them for a new release.

Debian Configuration :: Can't Receive System Messages
Mar 2, 2010I 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.
Debian Configuration :: Vanishing Boot Messages ?
May 4, 2010An 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.

View 8 Replies View RelatedDebian Configuration :: Get Cron To Send Messages In First Place Instead Of Root?
Mar 25, 2010The 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?

Jan 29, 2011I'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.
