better try using ssh2_* functions http://www.php.net/manual/en/function.ssh2-tunnel.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Unable to get output from exec "ssh remote-server 'ping -c4 ip'"
If you are just checking to see if the IP is pingable, but don't care about the output you could just test against the exit code: $host = 'hostorip'; $sshhost = 'hostorip'; $alive = trim( shell_exec( 'ssh ' . $sshhost . ' ping -q -n -c 5 -W 2 ' . $host . ' \>/dev/null 2\>\&1 \&\& echo "Alive"' ) ) == 'Alive'; var_dump( $alive ); I use a variant of the above with good success on Gentoo. Adam.

Hi, I need to develop an interface that will, for example, ping IPs from a remote server. So the php script will be hosted in a server with ssh access (key) to the remote server. I can make it work from the console but when I try $cmd = "ssh remote-server 'ping -c 4 ip'" exec($cmd, $ouput); the output is empty. the same command (with the remote-server and IP changed to the real ones) works fine from command line. I've added the key/config in the webserver's user .ssh directory so I am assuming that that there is something wrong with my setup. any ideas?
