Narrowed it down a bit further:  I can rsh to khan directly with no
command, but if I add a command, that's when the rsh fails:

[mrichter at sushi lane]$ 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: Mon Jul  7 11:59:59 from sushi
[mrichter at khan mrichter]$ ls
bin/      Documents/  lane608/  Pictures/  rls_607/    temp.xml
Desktop/  Download/   Music@    Public/    Templates/  Videos/
[mrichter at khan mrichter]$ exit
rlogin: connection closed.
[mrichter at sushi lane]$ 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
[mrichter at sushi lane]$

Sushi is my CentOS 5.2 machine, khan is our CVS server running:

[mrichter at khan mrichter]$ lsb_release -a
LSB Version:    1.3
Distributor ID: RedHatEnterpriseAS
Description:    Red Hat Enterprise Linux AS release 3 (Taroon Update 2)
Release:        3
Codename:       TaroonUpdate2

Any ideas?
