revised swapping IP addresses with another server in Linux quickly
minor text edit, so the user didn't assume that was the "full" (complete) line to put in their crontab

comment SSH login without password
Solaris ships with its own version of SSH (Sun_SSH), which doesn't include ssh-copy-id.

comment How to clean up server's hard disks before giving it away?
/dev/sda1 is just the first partition of /dev/sda. You probably still have at least one other partition on that disk (swap), possibly more... If that wasn't what you intended to do, and if shred is running from the hard disk you are destroying, you may need to ask someone to drop a CD into the drive and run that command. (Alternatively, you mentioned reinstalling the OS above - how would that be accomplished? Does somebody else do it? Do you do it via an out of band method? If you do it, you may be able to just run shred from a virtual console on the installer, depending on the OS.)

comment How to clean up server's hard disks before giving it away?
Depends on the speed of the disk, and the number of passes. But probably several hours with a disk that size. If you used the -v option, you'll be able to see the progress. You said "a 'Rescue' CentOS OS". Like a CentOS rescue CD/ISO? (I ask because if you launched shred from the same disk or partition you are wiping, don't stop and restart just to add the -v option. The disk would be partially destroyed by this point, and shred is only continuing to run because it is running in RAM, but restarting it would likely fail.)

comment SSH login without password
what are the directory permissions on ~/.ssh and authorized_keys? Solaris boxes are stricter about this than Linux. chmod 700 ~./ssh and chmod 600 ~/.ssh/authorized_keys should work on a Solaris server.

comment RHEL 6 x64: running 32 bit applications
which 32-bit packages do you need? RHEL makes many 32-bit libraries available for their 64-bit systems. For example, yum search libstdc++ yields both an x86_64 package and an i686 package.

comment CentOS 6 in production
Even 5.x is falling behind. RHEL 5.7 has been out since Jul 21st, and as of today, still no CentOS 5.7.

and you don't need the "base" and "update" sections in your rhnplugin.conf - those are for CentOS.

comment In Ubuntu can root overwrite any file?
so, as a workaround you could do something like: sudo sh -c 'date >> cron_email.log'
