If you take a RH6.2 computer & upgrade it to RH7.0, then you have with /etc/rc.d/rc3.d/S50inetd & /etc/rc.d/rc3.d/S50xinetd at the same time. So when you reboot, a daemon may take ports for telnet & ftp, while the other may manage talk & finger! (I had such a case!) Solution: the upgrade process must withdraw S50inetd.
I have not seen this happen in my testing - assigning to xinted owner.
xinetd obsoletes inetd, this can't happen. What does "rpm -qf /usr/sbin/inetd" give you?
It says netkit-base-0.10-37 I had this problem on 2 computers moving from RH6.2 to RH7.0 out of a bunch of about 10.
6.2 should have inetd in the inetd rpm... anyway, netkit-base has also been marked obsolete since 2000-10-31, so the fix should be part of xinetd-2.1.8.9pre12-2 and newer,
