How to chroot

Wed, 09/16/2009 - 18:21 — siteadmin

Here is a good link on how to Recover a Non-booting Linux System
https://askubuntu.com/questions/422928/how-to-reinstall-network-manager-...
or
http://roderick-greening.blogspot.com/2009/09/recover-non-booting-linux-...

and the core:

ubuntu@ubuntu:~$ sudo mount /dev/sda6 /mnt
ubuntu@ubuntu:~$ sudo mount /dev/sda1 /mnt/boot
ubuntu@ubuntu:~$ sudo mount /dev/sda7 /mnt/home

Verify everything looks correct before proceeding (i.e. you got the partitions correct and mounted in the correct places).

Next, you need to take care of /proc and /dev as follows:

ubuntu@ubuntu:~$ sudo mount -t proc none /mnt/proc

dynamic DNS

Sat, 08/29/2009 - 01:25 — siteadmin

To use a dynamic DNS system, register an account with http://www.zoneedit.com
Documentation on: http://www.zoneedit.com/doc/dynamic.html
download http://ddclient.sourceforge.net/
You will need to change the section for zoneedit near the bottom, plus at the top set the interval to what you want (from 300) and uncomment:
use=web
There may be a problem if the password contains punctuation characters

Samba Server Setup

Wed, 06/03/2009 - 14:50 — siteadmin

This is very "quick and dirty" using the CentOS gui tools as much as possible

-install server & open firewall to samba
-create office and supervisor groups and a /home/common folder
-create all users on server and make them part of office, (+supervisor)
-add all users to Samba with Windows names and passwords
-share all home drives and set user access on shares as appropriate
-set permissions in the directory at the root of each share, appropriate to users
-chmod g+w -R * #at the top level of each shared directory so groups can read and write

Xorg problems and resolution

Thu, 10/30/2008 - 14:14 — siteadmin

The best resources I found were:
How to create a modeline: http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
Some general tips: http://www.x.org/wiki/FAQVideoModes
A complex example: http://www.mail-archive.com/fedora-list@redhat.com/msg12682.html
Some detailed debugging tips: http://redhatcat.blogspot.com/2007/09/xorg-for-sharp-aquos-and-nvidia-88...

Using the last link, I found that there were three video ports on the card (DVI0, VGA0 and VGA1) and all my settings were being applied to the wrong one.

Here is the first part of redhatcat, on how to do debugging:
