Troubleshooting the Internet Services
Check the permissions on the files in the /usr/lbin
and /usr/sbin directories. The files ftpd, bootpd,
telnetd, rlogind, remshd, rexecd, rwhod, and
inetd must be owned and executable by root only. The
file fingerd should be owned and executed by bin
only. No other user should have permission to write
them, although all users can read them.
Table lists the entries that are required in the
/etc/services file.
