Shell Programming and Scripting

Yes but nothing was display on the browser......

If you had the exit(0) line, then that's what I'd expect. Anyway, now you are seeing errors show up in the error log, so at least we have this as a baseline.

Back to an earlier post (https://www.unix.com/shell-programmin...#post302267529) and an even earlier remark about user-names. The problem seems to be that when you run the command from the command-line, you are running the script with a particular user-id. It's possible (very possible) that this is not the same user as the one when HTTP runs it. AND/OR the $HOME directory is not set so that ssh cannot find the local .ssh configuration files which are required in order to confirm the identity of the remote host.

So, add this to your print out (after Content-type header), or to your error logs:

Code:

print "USERID=",$<," <br>\n";
print "HOME=",$ENV{'HOME'}," <br>\n";

If HOME is empty, you must set it to the home directory of the user that contains the .ssh/known_hosts file. (If you have root access, you can set /etc/known_hosts with that information.)

Code:

$ENV{'HOME'}='/home/joeblow/';

Do this before you do anything with ssh.

Setting the home environment solved the issue. Thanks for your help all.......
