Hi- Is chkrootkit the reason you believe you box was hacked? If so, please check the chrootkit site at http://www.chkrootkit.org They have a mailing list I don't have access to right now but there was a bit of conversation about false positives.

You cant also check in your /proc filesystem. If you have another server with the same OS version, you can try to do an md5sum on your ps and netstat command. This will show you if those command have been modify by the hacker..... A nice thing to do on your unix box, is to have some command burn on CDROM. Command like md5sum, ps, grep, ls, netstat, lsof etc.... If your system get hacker and binnaries are replace, you can use command burn on your CDROM and your are sure to use non modify version of it. Or use a ready only filesystem..... This is my 0.02$ CDN cents...
