kludge
Description:
Somehow if consecutive "rsh houdin -n ..." are issued too close,
a "Connection refused" result. Then /usr/local/krb5/rsh falls
back to ordinary rsh protocal which of course won't work either.
Solution:
if the houdin to be tested is houdin, wait for 5 seconds before
launching the 'rsh ...' command. Hopefully the system admin can
fix the rsh problem.
Platforms tested:
eirene talking to houdin.
