This is one of the most important apps on my machine. I don't know why everyone doesn't use it. I fear telnet....

[»] file format of DSA keys
by Oren Tirosh - May 11th 2000 15:06:10

OpenSSH uses PEM format for DSA key files which is incompatible with the SSH2 key file format. So far I couldn't get OpenSSH to authenticate with a DSA key to an ssh2 server because of this. I can't put the public key generated with OpenSSH on the ssh2 server and I can't get OpenSSH to use a private key generated with ssh-keygen2.

From my notes here is how I was able to do it:
On the client
1. upgrade the openssh to 2.2.x+
2. ssh-keygen -d -f $HOME/.ssh/id_dsa
3. cd $HOME/.ssh
4. ssh-keygen -x -f $HOME/.ssh/id_dsa > ssh2.pub

On fsecure server
5. copy ssh2.pub to $HOME/.ssh2/ssh2.pub
6. echo "Key ssh2.pub" > authorization

Hmmm... Looking at the manpage, neither -d or -x exists...
