We have a legacy setup with tru64 hosts that are currently configured for rsh, not ssh. I've installed the latest and greatest nagios on a relatively recent fedora host and have used plugins with ssh in the past. The problem is that rsh doesn't return status codes properly. Rather, it returns only the status code of rsh itself, not the command. A search implies you just need to echo $? with rsh. rsh linux to linux, I get this: linux1> rsh linux1 'date ; echo $?' Wed Jan 3 15:15:07 EST 2007 and trying to generate an error: linux1> rsh linux1 'bogus ; echo $?' bogus; Command not found. 1 So that looks ok but first problem is when I put into nagios commands define .... rsh $HOSTADDRESS$ 'mycommand; echo $?' The web page show "(No output!) Is it possible it swallows the quotes? Further, rsh behaves differently on tru64: linux1> rsh tru64-host 'date;echo $?' Variable syntax. Any ideas for these problems? Thanks and
