[CentOS] rsh problems in CentOS 5.2 (was "cvs command failure on 5.2")

Okay, I've narrowed the problem down quite a bit.  As previously
reported, in CentOS 5.2 I get this:

$ cvs log Makefile
poll: protocol failure in circuit setup
cvs [log aborted]: end of file from server (consult above messages if any)

Turns out this is a problem with rsh:

$ rsh khan ls
connect to address 10.24.15.48 port 544: Connection refused
Trying krb4 rsh...
connect to address 10.24.15.48 port 544: Connection refused
trying normal rsh (/usr/bin/rsh)
poll: protocol failure in circuit setup

Now, if I just reomtely login to khan (our cvs server), I get this:

[mrichter at sushi ~]$ khan
connect to address 10.24.15.48 port 543: Connection refused
Trying krb4 rlogin...
connect to address 10.24.15.48 port 543: Connection refused
trying normal rlogin (/usr/bin/rlogin)
Last login: Fri Jul  4 18:19:01 from viper
[mrichter at khan mrichter]$

Voila - I'm logged in.

Also, if I try an rsh from another machine (viper - FC1), I get this:

[mrichter at viper mrichter]$ rsh khan ls
connect to address 10.24.15.48: Connection refused
Trying krb4 rsh...
connect to address 10.24.15.48: Connection refused
trying normal rsh (/usr/bin/rsh)

So, what is it about rsh from CentOS 5.2 such that the kerberos
certification destroys its chances of success?  Alternative question:
what do I need to tweak to make this work?

Thanks.

PS: Google has lots of wrong answers on this, mostly really old and of
no use at all.
