Re: [cobalt-users] RAQ4 Some system files change ex: ls, top, netstat, login What's wrong ?



Either you have been rooted, or just havent installed a patch of some kind.
;)

I was following the thread, and my ls results are identical to Nucharin, and
yet has the same MD5 as yours.

Considering my box sits behind a pretty robust (and tight) firewall and IDS
box, I doubt I (we) have been rooted. I am not ruling it out, but its not
very likely. At least not based on the file size of ls.

Anyway, my washing machine is being rotated out of service next week(21 days
till the spin/rinse cycle. ), so if it is, no biggie. It gets reformatted
before being re-deployed.
