Re: Execute a perl script from PHP?

So an update to this: If I run the script manually using my own login it works. However if I try to sudo -su to the web server's username it never connects w/Net::OpenSSH. Which then leads to it failing the telnet part also. I'm guessing its a permissions issue that the webserver is not able to do the SSH but I get no log entries indicating any problems.

Maybe your web server machine runs SELinux or something that prevents the Apache user from making outbound network requests. If you can reduce the Perl script to a minimal, self-contained script to reproduce the problem, maybe somebody can find the reason why things don't work. Have you tried launching the script directly, without PHP in the middle? Maybe from a shell script or a tiny Perl script.	[reply]

There is also the potential that this is an environment issue or permissions. There are variables that can change where stuff is looked for on the system (LD_LIBRARY_PATH, PERL5LIB, PATH, ...) that may be set differently on a user-by-user basis. You could do an `env` from your own login and the login of the web server, and compare the differences. I would guess that the web server is a bit more restricted / limited / just plain different than your user's environment. --MidLifeXis	[reply] [d/l]
