Hi Anthony,

Yes, this is legit report. lop1 is cold turkey. Sorry, I should have
sent an email earlier but I was busy with other stuff. I my crystal ball
is correct AC adapter is fried. We had the problem with this little old
machine in the past. I do have an off brand AC adapter for it but it is
probably not worth the trouble. I was planning to retire lop1 soonish
anyway.

There are three shell-gateways available right now

bash.autonlab.org (was stable for me for over a month)
lop2.autonlab.org
lion.auton.cs.cmu.edu

hash-keys are posted on our Intrenet. I will probably add another virtual
shell gateways soonish.

Best,
Predrag
