note 124818 added to function.ssh2-exec

Running multiple commands shows this warning and second(and any next) command wont be executed: - PHP Warning: ssh2_exec(): Unable to request a channel from remote host in ... Solution with fclose($stream) does not work, but this is simple solution which works for me: <?php $connection = ssh2_connect('SOME SSH IP ADDRESS', 22); ssh2_auth_password($connection, 'username', 'passwortd'); //those commands are for some HUAWEI enterprise routers $stream = ssh2_exec( $connection, "screen-length 0 temporary\ndisplay isis name-table" ); stream_set_blocking( $stream, true ); $stream_out = ssh2_fetch_stream( $stream, SSH2_STREAM_STDIO ); echo stream_get_contents($stream_out); ?> first command is: screen-length 0 temporary second command is: display isis name-table which is executed with \n in the same line. You have to separete outputs of those commands later. Looks like ssh2_exec allocates exec stream in session you are connected in, and for freeing it , you have to ssh2_disconnect. Usualy you are ok to ssh2_exec one command then disconnect, then connect and ssh2_exec next command. This is how some other php libraries works as I have seen. But sometimes some variables are sesion dependent, and when you disconnect variables resets. ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.195 (proxied: 212.200.247.77) ---- Manual Page -- http://php.net/manual/en/function.ssh2-exec.php Edit -- https://master.php.net/note/edit/124818 Del: integrated -- https://master.php.net/note/delete/124818/integrated Del: useless -- https://master.php.net/note/delete/124818/useless Del: bad code -- https://master.php.net/note/delete/124818/bad+code Del: spam -- https://master.php.net/note/delete/124818/spam Del: non-english -- https://master.php.net/note/delete/124818/non-english Del: in docs -- https://master.php.net/note/delete/124818/in+docs Del: other reasons-- https://master.php.net/note/delete/124818 Reject -- https://master.php.net/note/reject/124818 Search -- https://master.php.net/manage/user-notes.php
