[Vagnekman-users] vagn: access restricted

[Per Lundqvist]

Due to security implications affecting vagn we have decided that until
the service stop next Wednesday has occurred, login to vagn is
restricted from NSC and from ekman.pdc.kth.se.

If you are using public key authentication to access vagn, you now
need to log in with agent forwarding through either ekman.pdc.kth.se
or a NSC resource (e.g. tornado.nsc.liu.se or
gimle.nsc.liu.se). Example:

If not already done, add ssh private key to local ssh agent:
   $ ssh-add -c

Log in to ekman:
   $ ssh -A -K -o GSSAPIDelegateCredentials=yes -o GSSAPIKeyExchange=yes -o GSSAPIAuthentication=yes perlundq at ekman.pdc.kth.se

Log in to vagn (using different user name than on ekman):
   $ ssh perl at vagn.nsc.liu.se

The same goes for logging in via tornado or gimle, but with less
arguments:

   $ ssh -A gimle.nsc.liu.se
   $ ssh vagn

We are sorry for this inconveniance. If you need help or if this
results in severe problems for you then please contact us at:
