Greetings,

With Scientific Linux 5.1/5.2 on i386/x86_64 we are struggling a bit
to get rsh running. The current situation:

[andy@horst2 ~]$ /usr/bin/rlogin -l andy meyer
Last login: Wed Jan 21 10:00:06 from bolt
[andy@horst2 ~]$ /usr/bin/rsh -l andy horst2 date
Wed Jan 21 10:25:34 CET 2009
[andy@horst2 ~]$ /usr/bin/rsh -l andy meyer date
poll: protocol failure in circuit setup
[andy@meyer ~]$

Summary:
- rlogin to another machine works.
- rsh to the local machine works.
- rsh to another machine fails.
- rsh to another machine works if the firewall is disabled on the
local/client machine (not shown).

Links and/or suggestions gratefully received,

Andy.
