also you may use non-kerberized telnet daemon without adding '-a off' argument, just change 'server =' option:<br />
/usr/sbin/in.telnetd<br />
instead of<br />
/usr/kerberos/sbin/telnetd<wbr /><br />
<br />

Anyway, why do you want to use telnet in the first place since you have SSH? SSH is much better and securer than telnet. If I were you I'd completly disable telnet and just use SSH.

I have a RHEL3 box. I only have 2 users setup on this box in addition to root:<br />
<br />
user1<br />
user2<br />
<br />
User1 can SSH and telnet into the box. This user is a part of the &quot;root&quot; group.<br />
User2 can SSH but not telnet into the box. This user is also a part of the &quot;root&quot; group. I get the following error:<br />
<br />
login: User2<br />
Password for User2:<br />
login: Cannot resolve network address for KDC in requested realm while getting initial credentials<br />
Login incorrect<br />
<br />
I am positive that the password typed is correct. Why can't user2 telnet in? <br />
<br />
Thanks!

RHEL3: All users can SSH into box fine, but some cant telnet

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
