It was filtering, but now I've opened the port to listen to my machine, which is running my web server (where all php scripts qre running). So, that's not a problem now. I've checked it (SSH) on the terminal, it's working fine with root as well as other users. Now, problem is, for other users it asks for password, which i dont want to surpass.
Your idea of running encrypted tunnel to use telnet services is good, but i cann't use it, cause i've blocked that port, and i dont want to open it. Second thing is, yes I'm using system() for command from php and it's not showing any result. May be you r right that, it's just sitting waiting for password. If, you've any idea to deal with it, please let me know. Anyway, thanks a lot for your time and great help.
