Re: sshd problems (ssh_host_key Bad file descriptor, and no ssh_host_dsa_key)

I'm not sure about the Bad file descriptor error, but here's how I got
sshd to work in case it helps.

cd /etc/ssh
ssh-keygen -f ssh_host_key

This should get protocol 1 to work.

I generated the dsa key on my linux workstation then transfered
ssh_host_dsa_key and ssh_host_dsa_key.pub to the ipaq /etc/ssh dir.

Here's the command I used to generate the dsa key on my workstation:

ssh-keygen -t dsa -f ssh_host_dsa_key

btw, just to be safe I deleted these 2 dsa files on my workstation.

I have no idea if this is the recomended way to get a dsa host key on
the ipaq.
