If you arrange proper ssh keys for noninteractive logins, your program becomes as simple as:

Code:
my $subinfo=`/usr/sbin/ssh -i /path/to/identityfile username@172.24.13.130 /bin/getinfo.sh $name`;

...

You use keys like this, with minor differences -- the -i is because your CGI script isn't an interactive login and likely has no home folder to find ~/.ssh/ in. You'll have to pick your own place to put it -- preferably someplace apache itself refuses to touch (which won't stop your perl script or ssh from getting it).

The identity file itself should belong to apache:apache (or whatever user/group your webserver uses) and be set 0400. The folder should also belong to your webhost user/group and be set 0700.
