May I add another noob question?
I was trying to ssh to the device over the cellular network and failed miserably. If I interpret "netstat -lntu" correctly port 22 (which I was using) is open:
I have a public IP, it works to ssh to the device over my local wifi network and from the device on both cell and wifi network.
Do the cell operators usually have some form of firewall stopping connection attempts or am I missing something else?

You can run the command ifconfig on the n900 to see what IPs you have configured. So using that you can see what IP is configured on the cell network interface (it is phonet0 if I recall).
Mostly I think cell operators would give you an IP in a private address space, like 10.x.y.z or 192.168.x.y and send your outbound traffic through what's called a NAT gateway, so inbound traffic across the cell network would normally be impossible.
I'm not sure, but it sounds from your post that you're trying to ssh to your public WLAN IP across the cell network?
That wouldn't work because no-one (apart from you!) knows that IP is on the end of your cell network connection, so it can't be routed there. (Sorry if I misunderstood, it's a little hard to make out just what you're trying to do... Mentioning some example interfaces and IPs would help..)

To try to clarify, everything is fine when the N900 is connected to my wlan. I can ssh to the device on the local network, using the IP my router has assigned to the N900.
What I ask about is ssh:ing to the N900 when it is connected to the cellular network, using the IP assigned to it by my cell network operator. I can tell I receive a public IP from e.g. checkip.dyndns.org. It is also verified by the Personal IP widget. Using that IP I try to ssh to the N900 from my PC.

Ah, ok, I guess it must be firewalled out by your telco somewhere along the way..
If your PC supports the traceroute command, you could try
to see if that shows where the blockage is..
Certainly, as far as I understand it, you are correct in your earlier post where you say that sshd is listening on all interfaces and should be reachable if nothing else is blocking it.
If your PC supports the traceroute command, you could try
traceroute -n -T -p 22 <n900 IP>
Certainly, as far as I understand it, you are correct in your earlier post where you say that sshd is listening on all interfaces and should be reachable if nothing else is blocking it.

nice. it worked great until I stopped and restarting ssh server again. now, the password isnt working anymore. the server is open and running again, but the password don't work anymore. any ideas?
have not changes pwd for root. used rootish to get root access.
get root terminal (open terminal, type "root")
/etc/init.d/ssh stop
/etc/init.d/ssh start
tried to uninstall ssh server again and reiinstall it again, but i wont get the pop up for the password again. I know the password, and can ping my n900, but can't connect.
