Thanks a lot for your advise. In fact, I thought about that as well, but I
do not know how to switch the user from apache to a real user when I send a
request through Web browser. I even tried to use "ssh_rsa" method instead of
password authentication. But I got the same error. Command line fine, but
through web server I got an error in the first place (ssh2_connect). I am
wondering do you have any suggestion. Thanks a lot.
