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) 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 only
secsh-connection: pty+shell or command, flow control works (window adjust)
tcp-forwarding: -L works
dss: verification works,
key database in ~/.ssh/known_hosts with bits == 0 hack
dss: signature works, keygen w/ openssl
client interops w/ sshd2, lshd
server interops w/ ssh2, lsh, ssh.com's Windows client, SecureCRT, F-Secure SSH Client 4.0
server supports multiple concurrent sessions (e.g. with SSH.com Windows client)
todo:
re-keying
secsh-connection features:
tcp-forwarding, agent-fwd, x11-fwd
auth other than passwd:
pubkey, keyboard-interactive
config
server-auth w/ old host-keys
cleanup
advanced key storage?
