ssh2 mod and exec function

[gonchi]

Hi,

Something very strangne happens with the function ssh2_exec, i can't
read the stream answer after execution in the remote computer. I work
with apache 1.3.30 and php 4.3.10 , libssh 2.0.5 . the ssh2 module
looks to work correctly but sftp functions cause a big delay causing
server timeout and ssh2_exec can't read the output. Tryed many things
recommeded in php website and forums but always the first ssh2_exec
reading success and the following ones fail.

$stream=ssh2_ex ec($conn_id,'/usr/bin/ls ./public_html');

I tryed to read the output with:

stream_set_bloc king( $stream, true );
$cmd=fread( $stream, 4096 );

after

while($line = fgets($stream)) {
$cmd .= $line;
}

and

while( !feof($stream) ) {
$cmd .= fgets($stream)
}

Nothing success to catch the output for the second execute order. In
the same process only the first exec could be read.
Anybody know
