Hi, I can connect to my N900 by using command below.

ssh root@192.168.2.15:

But the precondition is that I open and start Mad Developer on N900 already.
And if I close Mad Developer now, I still can connect to N900 by ssh.

But if I restart my N900 and don't open Mad Developer any more, then I try to connect to N900 by ssh, I get the response like below.

ssh: connect to host 192.168.2.15: port 22: Bad file number

Does anyone know why and how to solve it? Thanks!
