Beware that this can be a fix that causes more problems. It's very tempting to let the web server run as root--which opens up a big can of security worms.

This is a very common problem. When you run the script from the command line, you are running it with different privileges and a different path than when the web server runs it.
Most likely, either the command is not in the path for CGI scripts (try setting $ENV{PATH} or calling the command with the full pathname), or the web server, which should run as 'nobody', doesn't have permission to run the command properly.

All, i am new to cgi. Please let me know why I dont get the data printed? I have abc.cgi in /var/www/cgi-bin
When the $cmd is "ls" I get the filenames when I visit localhost/cgi-bin/abc.cgi
But when the $cmd is the snmpquerry, I get nothing on the page, though I get the desired output(value of sysContact.0) when I run the script in commandline.
