Do Computer Geeks and Gearheads Overlap?

Johnath asks: "One of the great things about finally owning a place with a garage is that it's given me a chance to start taking apart my car and putting it back together. I'm certain I'm not the only one here who does so. The analogies between custom cars and custom computers are as obvious as they are numerous: the quest for higher performance, the analysis of detailed benchmarking and comparison studies, the fanatical brand loyalty -- a nitrous tank on an inline-4 is materially identical in my mind to a 4" heatsink on an overclocked duron. How much overlap is there between these groups, how many people here are car geeks? My preference is to optimize for efficiency and mileage over power gains, but I'm interested in car-hackers of all persuasions. Where do you go for geek-level treatments of oil brands, exhaust options, and dyno results? Is there a gearhead Slashdot hiding out there, or only the brand-specific boards like myfordfocus.com?"

kerberised telnet/rcp

[Paul Jakma]

You want kerberos V5 telnet/rcp:

[paul@fogarty paul]$ echo "kerberos is nifty" > /tmp/kfile
[paul@fogarty paul]$ rcp /tmp/kfile hibernia:/tmp
Trying krb4 rcp...
trying normal rcp (/usr/bin/rcp)
[paul@fogarty paul]$ telnet -a hibernia
Trying 192.168.0.3...
Connected to hibernia.somewhere (192.168.0.3).
Escape character is '^]'.
[ Kerberos V5 accepts you as ``paul@SOMEWHERE'' ]

You have mail.
[paul@hibernia paul]$ cat /tmp/kfile
kerberos is nifty
[paul@hibernia paul]$ logout

note that you can optionally encrypt the data stream too by specifying -x to either telnet or rcp. So next time someone tells you telnet, rcp are insecure you can tell them they are wrong! :)

Note there are is also a kerberos version of FTP server/client available.
