Bug description: SSH does not disconnect gracefully
Description:
------------
I have a page that refreshes every minute. In that page, I open an ssh
session and obtain data. There is no way to close the ssh connection. On
reload, php opens a new connection but does not terminate the last one or
reuse the existing one.
Running a NETSTAT command reveals numerous connections in the CLOSE_WAIT
status after several minutes.
Can a close SSH option be included?
Reproduce code:
---------------
<?php
$connection = ssh2_connect('myserver',22);
ssh2_auth_password($connection,'username','password');
$stream = ss2_exec($connection,'df -k',FALSE);
stream_set_blocking($stream, TRUE);
$output = fread($stream,4096);
fclose($stream);
echo $output;
?>
Expected result:
----------------
Connection should show nothing
Actual result:
--------------
netstat -a shows
----------------
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
TCP myweb:xxxx myserver:22 CLOSE_WAIT
