Status: No Feedback
Bug Type: Program Execution
Operating System: SuSE Linux 8.1
PHP Version: 4.3.1
New Comment:
I am experiencing this same issue on SuSE 9.1 with PHP 4.3.4 and
OpenSSH 3.8. This is a more recent PHP than the one you offered up to
solve the problem.
I have narrowed it down to exec'ing ssh specifically. I am using
passwordless public/private key authentication to a user account with
very limited priveledges on the remote host.
The ssh command to the remote host is actually executed, but PHP never
comes back.
The problem occurs using system(),shell_exec(), and popen().
I have reproduced this with a script as simple as:
<?php
system("ssh [EMAIL PROTECTED] mycommand_with_no_output");
?>
HTML GOES HERE
The result is that PHP never comes back, and it does not error out
either. Executing this via the command line works fine, executing it
as a web-script hangs permanently.

Using ssh through the various exec functions usually hangs
php execution. Very strange that:
exec('/usr/bin/scp [EMAIL PROTECTED]:/what/ever/file .')
works fine, while
exec('/usr/bin/ssh [EMAIL PROTECTED] /what/ever/execfile'),
where "execfile" is any executable file, makes the
execution of the php script hang.
Any help/reproduction/confirmation of this very
appreciated.
