lop2 is now shell

[Predrag Punosevac]

Dear Autonians,

Some of you have noticed that shell.autonlab.org shell gateway become
unavailable some time ago due to the hardware failure. After trying
unsucessfully to repair the server and to replace it with the virtual
instance I decided to rebuild seldomly used shell gateway
lop2.autonlab.org (port 2222) as a shell.autonlab.org.

This gateway is designed to provide Auton Lab LDAP account holders with
the complete access to the Lab's computing infrastructure including DMZ
zone. It is not intended to be used as X2Go proxy. Moreover even your
home directories are not mounted on this particular gateway so that it
continues to be available in the case of main file servers failures.
That means that this machine is ill suitable for file transfer and that
the ssh keys transfered to this machine will not be available anywhere
else. Folks who had to jump through the hoops to access DMZ will
appreciate.

Be worned that if you have used shell.autonlab.org in the past you have
to remove the line containing shell.autonlab.org from the file 

.ssh/known_hosts

RSA key fingerprint of the "new" machine is 

56:12:5c:fb:39:9f:1e:62:4d:66:e4:57:28:a1:46:91

Best,
Predrag

P.S. Based on usage pattern my feelling is that 3 shell gateways are
sufficient for forseable future.
