As a general rule, you should avoid transmitting potentially sensitive data using unencrypted protocols (ie. logging in as root using telnet is one of the more dangerous things you can do). Try substituting encrypted ones instead (use ssh instead of telnet) or if you can't find an encrypted alternative, try piping the insecure protocol through an encryption tunnel (ssh and encrypted netcat (CryptCat) are well suited for this task). There are alot of other things you can do including checking all your boxes for promiscuous interfaces (chkrootkit) and using a network topollogy which is less sniffer-friendly (use switches instead of hubs). Check out this FAQ for more:
