Replying on my own post for archival reasons: The error was in /etc/hosts.allow. I forgot to add a line "in.rshd: FQDN" in hosts.allow on the machine I imaged and then used to install to a bunch of other machines. Easy to miss though, there are a dozen or so other lines in there allowing other daemons and stuff. Fixing that, now "rsh remote-machine vmstat" works as expected. -- /Sorin -------------- next part -------------- A non-text attachment was scrubbed...
