+howto:
+	1) generate server key:
+		$ ssh-keygen -d -f /etc/ssh_host_dsa_key -N ''
+	2) enable ssh2:
+		server: add 'Protocol 2,1' to /etc/sshd_config
+		client: ssh -o 'Protocol 2,1', or add to .ssh/config
+	3) DSA authentication similar to RSA (add keys to ~/.ssh/authorized_keys2)
+	   interop w/ ssh.com dsa-keys:
+		ssh-keygen -f /key/from/ssh.com -X >> ~/.ssh/authorized_keys2
+	   and vice versa
+		ssh-keygen -f /privatekey/from/openssh -x > ~/.ssh2/mykey.pub
+		echo Key mykey.pub >> ~/.ssh2/authorization
+
+works:
+	secsh-transport: works w/o rekey
+		proposal exchange, i.e. different enc/mac/comp per direction
+		encryption: blowfish-cbc, 3des-cbc, arcfour, cast128-cbc
+		mac: hmac-md5, hmac-sha1, (hmac-ripemd160)
+		compression: zlib, none
+	secsh-userauth: passwd and pubkey with DSA
+	secsh-connection: pty+shell or command, flow control works (window adjust)
+		tcp-forwarding: -L works, -R incomplete
+		x11-fwd
+	dss/dsa: host key database in ~/.ssh/known_hosts2
+	client interops w/ sshd2, lshd
+	server interops w/ ssh2, lsh, ssh.com's Windows client, SecureCRT, F-Secure SSH Client 4.0, SecureFX (secure ftp)
+	server supports multiple concurrent sessions (e.g. with SSH.com Windows client)
+todo:
+	re-keying
+	secsh-connection features:
+		 tcp-forwarding, agent-fwd
+	auth other than passwd, and DSA-pubkey:
+		 keyboard-interactive, (PGP-pubkey?)
+	config
+	server-auth w/ old host-keys
+	cleanup
+	advanced key storage?
+	keynote
+	sftp
