Keywords: linux ubuntu postfix Return-Path Sender From
My family connects to my mail server in order to send mail. But everyone has mail addresses that differ from their login names. On sending mail, postfix would add a Return-Path header matching my username on the mail server. In order to have the correct Return-Path added, I created /etc/postfix/generic with the following content:
local_user1@pjcj.net user1@example.com local_user2@pjcj.net lonelyboy99@example.com
And added to /etc/postfix/main.cf:
smtp_generic_maps = hash:/etc/postfix/generic
Then run:
# postmap /etc/postfix/generic # service postfix restart
Passing that mail through another server running exim4, I added the following lines to /etc/exim4/exim4.conf:
no_local_from_check untrusted_set_sender = *

Keywords: linux ubuntu notion
I use Notion as my window manager under Ubuntu. Notion is a fork of Ion.
Under Ubuntu 11.10 you can set Notion as your default window manager by creating the file /usr/share/xsessions/notion.desktop with the contents:
[Desktop Entry] Encoding=UTF-8 Name=Notion Comment=This session logs you into Notion Exec=notion Icon= Type=Application
Then edit /etc/lightdm/lightdm.conf:
user-session=notion
and if you want to automatically login set:
autologin-user=XXX
where XXX is your username.

android.process.media has stopped unexpectedly
With Cyanogenmod I kept getting the message:
"the process android.process.media has stopped unexpectedly"
when running Market or a music player.
The fix for me was to umount and then remount the SD card.

Keywords: Webalizer Geoip database package missing dependency
I was getting the following error message from cron:
Error Opening file /usr/share/GeoIP/GeoIP.dat
Turns out it was coming from webalizer. It seems that there is a package dependency missing. The solution was fairly simple:
aptitude install geoip-database

Cron on a Linksys WRT54G Router
Keywords: linksys wrt54g router alchemy
Every so often my Linksys WRT54G router will stop accepting connections. The simplest solution is just to reboot it. The trouble occurs when that happens and I am not near the router. So I wanted to set up a cron job to reboot it every night.
ssh into the router and run these commands:
nvram set rc_startup='#!/bin/sh echo "0 5 * * * root /sbin/reboot" > /tmp/cron.d/reboot touch /tmp/crontab ' nvram commit nvram get rc_startup
The first four lines set up a startup command which writes the cron line after each reboot, and touches the crontab to get cron to reload. The fifth line commits the command to the nvram and the final command simply prints it out to check.

Canon PIXMA MX860 on Ubuntu 9.10
Keywords: Canon PIXMA MX860 ubuntu install
MX860 drivers for printing and scanning can be downloaded from Canon. Uncompress them and cd into the created directory:
$ tar xvzf cnijfilter-mx860series-3.10-1-i386-deb.tar.gz $ cd cnijfilter-mx860series-3.10-1-i386-deb
Installation is performed by runing the install.sh script. The script tries to determine whether to use rpm or dpkg but got confused when it found both on my system. This can be fixed quite easily by forcing the issue:
$ perl -pi.bak -e 's/rpm --version/XXX/' install.sh
Then install with:
$ sudo ./install.sh
Do exactly the same with the driver for the scanner, scangearmp-mx860series-1.30-1-i386-deb
If the printer is already on the network it can be configured with System -> Administration -> Printing and then clicking on New.
