I have a small 'test.cgi' file where I'm just trying to ssh to a router to get some commands (the entire project is a BGP Lookingglass but this is where the problem lies).

It runs fine from command line, as the www-data user that is executing from apache (at least based on the ENV vars), but when I run it from the browser it's just a blank page.

I checked to make sure that 755 was everywhere as appropriate, for now (at least until I figure this out) www-data is able to login and like I said runs the script fine...

I checked the socket directory to make sure it was permed right as well and did some searching before posting (don't want to be shame flamed!).

Here's the code:

#!/usr/bin/perl
use strict;
use warnings;

use Net::OpenSSH;
use File::Temp qw/ tempdir /;

# necessary minimum for CGI
print "Content-type: text/plain\n\n";

# prepare temp dir
my $temp = "/home/www-data";                                          
+  

my $login_user= "xxxxx";
my $login_pass = "xxxxx";  


# open SSH session
my %opts = (
    user        => $login_user,
    password    => $login_pass,
    ctl_dir     => $temp, 
    strict_mode => 0            ## NOT recommended - see my comments
);

my $ssh = Net::OpenSSH->new("n.n.n.n", %opts);
$ssh->error
    and die "Couldn't establish SSH connection: ". $ssh->error;

# perform command and print output

my @lines = $ssh->capture("sh int desc")
    or die "remote command failed: " . $ssh->error;
print "OUTPUT<br>\n";
print @lines;

and... Here is the console output (mostly :-)

Also, in apache/errors.log I get:

34 is the 'my @lines' line... Any thoughts?
