Using lsof, netstat, ls, ps, looking through proc with ls, cat, etc. is likely to not work if there's a rootkit on the

Get some statically linked versions of these bins on to the server, and hope they haven't patched your kernel.
See if you can get a binary of busybox which has those tools and they're all contained in the binary. It should run from any folder.
