comment After Hours Server Monitoring Procedures
As long as its on 3G or CDMA its reasonable, i pull 1.5-3mbps down on my phone, more then enough to do VNC, RDP, SSH, anything i would usually need to do at 2AM when X service fails for whatever reason. I use Verizon myself, with a VX6800. Tethering on Verizon isn't as nice as AT&T, however i find that Verizon's signal is a bit better, which is my primary focus, is being able to get online when & where i need to.

comment My linux box has been hacked. Some files are undeletable even by root. How can I replace them?
a cleaned compromised system is still a compromised system. Its time to backup relevant data, and reformat.

comment Problem mounting an NFS drive using autofs on CentOS5.3
did some research : autofs has lower overhead, interesting. Might need to do some research & implement this on our servers.

comment Postfix performance
with 400+ load i'm surprized the systems doing anything, if your sending OUT 1 million messages a day through 1 system, i would suggest definately to improve your disk IO (Ramdisk, Raid), and probably move to a more clustered option, I'm sure at 400 load your server's moving mail quite slowly.

comment Postfix performance
Couldn't have said it better myself. I noticed 3. as well, sda and sdb with no partitions could be causing some slowdown, or at least its not an efficient use of the disks in the system.

comment Best system administrator accident
i've done that EXACT same thing, and wholeheartly agree -- there needs to be a "Are you sure??" pop up!! Luckily for me it was on a virtual server so we just had a bunch of websites go down for 3-4 minutes while i logged into the actual terminal of the box to bring it back up.
