I am very new to the N800, but pretty familiar with Linux in general so I need a few pointers to head me in the right direction. I have managed to get osso-xterm and dropbear installed, correctly I think. ifconfig tells me the ip address of my N800. ps -ax shows that dropbear is running (I assume this is the ssh server process?) but /etc/dropbear/log doesn't contain any useful information so maybe it's not running. So here's the questions:

1) I can ping my PC from the N800, but I can't ping the N800 from the PC. Is there a default firewall running, or do I need to do something else to allow access to the N800?

2) I found what I assume is the ssh client at /use/lib/apt/methods/ssh and when I run that to connect to my Linux machine I get the following:

100 Capabilities
Version: 1.0
Send-Config: true

and that's it. I can't connect and there's no sign of a connection attempt in the Linux machine's logs. I can't find any logs files on the N800 yet so I'm stuck on that end too.

3) When I do get the connection to work, what are the default root and user passwords that I use to log in to the ssh server? I've tried using passwd to change the user password and it tells me that I can't.

Thanks for any help.

Or you could uninstall dropbear and install openssh instead (sudo gainroot; apt-get install ssh) - always works for me.

Your N800 should be ping'able from a PC under normal circumstances.

The default root password on the N800 is "rootme", and user does not have a password so add a public key to ~user/.ssh/authorized_keys for user and you should be able to ssh straight in from your Linux box.

Thanks very much Milhouse. I deleted dropbear and installed ssh as you suggested. The sshd process is running and I can ssh to myself on the N800. And I can now ssh into my Linux servers, which was really the main point of the exercise. So that's good progress.

But I still can't ping or ssh to the N800 from anything else. I have several other windows and linux boxes on this network and they can ping each other, but nothing can ping the N800.

netstat -lt lists the sshd process as listening. Under the Local Address column it says *:ssh which I assume means that it is listening on all network addresses.

This does have iptables running but iptables -L shows that all policies are set to ACCEPT so that shouldn't be a problem.

I've been all through the control panel and don't see any other security items so why can't I ping this thing?
