The problem is that you are using the KRB5 enabled version of 
telnet/ftp.  If you type in `which ftp` and `which telnet`, you should 
see that they are in /usr/kerberos/bin.  If you aren't using kerberos 
for authentication, you can remove /usr/kerberos/* from your path (or 
remove krb5*), or you can bump up /usr/bin in the path list.

It looks like the PATH is set in /etc/profile.d/krb5.csh (for tcsh/csh) 
and /etc/profile.d/krb5.sh (for bash).  You can either move them (e.g., 
to /root), or you can append kerberos instead of prepending it:

Instead of:
PATH=/usr/kerberos/bin:${PATH}

switch it to:
PATH=${PATH}:/usr/kerberos/bin

for all instances.
