Login cluster
|
|
-------------
|
|
|
|
The login cluster allows users to run interactive programs. The
|
|
cluster consists of several nodes `llcN.psi.ch`, where N is 1, 2,
|
|
or 3. There is also a load-balancer, `llclb1.psi.ch`, which uses IPVS
|
|
with a round robin policy to distribute incoming connections.

|
Jump hosts
|
|
----------
|
|
|
|
Many servers can only be accessed via SSH through one of the two jump
|
|
hosts, `wmgt01.psi.ch` and `wmgt02.psi.ch`. These two systems require
|
|
two-factor authentication (currently using a Cryptocard dongle) and
|
|
offer a very restricted environment.
