Never could get ssh2dos to connect properly, but the telnet
client that ships with ssh2dos has better performance than
any of the other telnet clients I tried, including the mTCP
client and the NCSA client. I setup S/Key on SDF so I could
login using one-time-use passwords, for at least some kind
of security. So far, everything is working well! Now, time
to get some more things done on the new CDC 6500 at the
Living Computer Museum!
