I have a perl script that uses Net::OpenSSH and Net::Telnet. I am able to run the script from the command line of my server (solaris) and it seems to run correctly, including the ssh and telnet parts.

However, if I try to exec that script from php it doesnt work. The files the script is supposed to create do not get created, and in the error_log I see some errors related to libssh2.so and ssh2.so. However, my PHP code has no SSH related lines. Only the Perl does.

I see this line in the log quite a few times:

[Fri Apr 01 15:11:57 2016] [warn] (128)Network is unreachable: connect
+ to listener on [::]:443
[download]

I also see this:

ssh: illegal option -- M
Usage: ssh [options] host [command]
Options:
  -l user     Log in using this user name.
  -n          Redirect input from /dev/null.
  -F config   Config file (default: ~/.ssh/config).
  -A          Enable authentication agent forwarding.
  -a          Disable authentication agent forwarding (default).
  -X          Enable X11 connection forwarding.
  -x          Disable X11 connection forwarding (default).
  -i file     Identity for public key authentication (default: ~/.ssh/
+identity)
  -t          Tty; allocate a tty even if command is given.
  -T          Do not allocate a tty.
  -v          Verbose; display verbose debugging messages.
              Multiple -v increases verbosity.
  -V          Display version number only.
  -q          Quiet; don't display any warning messages.
  -f          Fork into background after authentication.
  -e char     Set escape character; ``none'' = disable (default: ~).
  -c cipher   Select encryption algorithm
  -m macs     Specify MAC algorithms for protocol version 2.
  -p port     Connect to this port.  Server must be on the same port.
  -L listen-port:host:port   Forward local port to remote address
  -R listen-port:host:port   Forward remote port to local address
              These cause ssh to listen for connections on a port, and
              forward them to the other side by connecting to host:por
+t.
  -D port     Enable dynamic application-level port forwarding.
  -C          Enable compression.
  -N          Do not execute a shell or command.
  -g          Allow remote hosts to connect to forwarded ports.
  -1          Force protocol version 1.
  -2          Force protocol version 2.
  -4          Use IPv4 only.
  -6          Use IPv6 only.
  -o 'option' Process the option as if it was read from a configuratio
+n file.
  -s          Invoke command (mandatory) as SSH2 subsystem.
  -b addr     Local IP address.
login failed: filehandle isn't open at /opt/apache/htdocs/enrc/cgi-bin
+/metro_cm_tool.pl line 130

The PHP code:

<?php

exec("/usr/bin/perl522/bin/perl /opt/apache/htdocs/enrc/cgi-bin/metro_
+cm_tool.pl");

?>
[download]

I cant figure out what PHP is doing differently than when I run the script from the command line directly.
