Physically diconnent the box from the network. Reinstall all the binaries that are supposed to be there from CDROM, and seriously consider deleting any executable that can't be traced to a Debian package and that you don't remember installing. One way to do this would be "find / -type f -perm +111 -exec dpkg --search {} \;" -- files that belong to a package will be printed like: bash: /bin/rbash [package] [filename] and ones which don't will get something like: dpkg: /bin/getopt not found Remove any suspicious looking accounts from /etc/passwd and /etc/shadow along with any files owned by those accounts, and make sure all that remain either have a password or an asterisk in the second field of the shadow password file. Edit all unecessary/mysterious services out of /etc/inetd.conf. Change all your passwords. Reboot the machine. Consider setting up a tight firewall with either ipfwadm or ipchains (for kernels 2.0.* and 2.2.*, respectively). I'm probably forgeting lots of things. > Any boffins out there may want to know that the loggins seems to come from > 195.146.109.166.
