Quick-notes
For
a
Hot-Clone:
On source machine:
Download script
chmod 755 rsync_backup_local.sh
Edit the top of the script with your values
Run the rsync_backup_local script.sh on the source machine
Shutdown services like mysql and postfix etc.. (Alternatively do a
mysql dump)
Run it again (runs really fast this time)
On target machine:
Install a base system with a "alternate cd" on the new machine
At boot, type in "cli" this will choose no
software, and finish the installation.
Edit rsync_restore_local to your values
Run the rsync_restore_local script.sh on the new machine
When done reboot the machine. It's that easy..
NOTE: You
may have to run dpkg-reconfigure xserver-xorg on the new machine.
Note:
These are working scripts. You
MUST edit to your specifications.
Note:
I use the
rsync_backup_local to upload
this web
pages and files. I first copied the
script and gave
it the name rsync_backup_upload, edit it, then set a cron job for it.
Of course, you could run the scripts in a cron one right after the
other by doing this. /bin/rsync_backup_channelvar.sh
&&
/bin/rsync_backup_ns1.sh && /bin/rsync_backup_mx2.sh
. Notice the && sign..
Note:
To backup our home server, I copied rsync_backup_local and gave it the
name rsync_backup_homeserv. Edited the top of the script and set a cron
job.. We find the backup script simple and very handy.
This script is meant to be run after installation of Ubuntu or Debian.
It will install packages like zip, arj, dnsutils, etc.
Post_Install will also write a decent .bashrc and .vimrc file for the
root user, set config-tools to numlock-on etc.. Creates a
sample
/etc/network/interfaces.tweak. Adds a line /etc/profile to send an
email alert of shell access to root@localhost (which should be
alias to the proper user). Backs up all files it
touchs with a .tweak extension so you don't lose your old settings..
Post_Install will also ask if you'd like to download the
current rsync_backup_local.sh and rsync_restore_local.sh. If those
files exist, it will NOT replace them. You'll have to manually remove
or rename them first.
Edit to your liking..
Keymaker
(From the commandline install by using dpkg -i keymaker-0.1-all.deb)
Easy install from command line as root
wget
http://programs.rcrnet.net/keymaker/keymaker-0.1-all.deb
dpkg -i keymaker-0.1-all.deb
Get tired of trying to
remember the commands to create ssh keys and upload them to another
linux machine?
The "keymaker" program creates your keys if they do not exist.
Then, will upload the keys to the destination using any connection
details you may need to give it.
Examples:
keymaker root@server.mynet.com
(include user on destination)
keymaker server.mynet.com
keymaker server.mynet.com -p 1111
(specifies port 1111)
Keymaker is a simple script installed to /usr/sbin/keymaker
You may customize it to your liking if you wish.
Version
(From the commandline install by using dpkg -i
version-0.1-all.deb)
Easy install from command line as root
wget
http://programs.rcrnet.net/version/version-0.1-all.deb
dpkg -i version-0.1-all.deb
After all these years,
linux still lacks a
"version" command.
This command makes it simple.
To find your ubuntu version:
version "distro"
Example:
version ubuntu
version debian
To find a package version:
version "packagename"
Example:
version postfix
To find kernel version and if you are running 32 or 64 bit
version kernel
Junkwatcher.ini - Needs to be in same directory
This
program watches a directory specified and alerts you if any directory
under that directory exceeds the age specified and offers to delete it.
We use this program at work to keep an eye on a large directory we use
for temporary backups. We often forget to delete them later.
Junkwatcher helps us keep it cleaned out. Just edit the .ini
file. There is no install. It's portable.
Utility to quickly change proxy settings on a local machine or the
entire network.
proxy.exe also alerts any open instances of Internet Explorer the proxy
has changed.
