Remote access to EECIS systems is available via SSH. For links to client software, see UseSSH. All EECIS systems have SSH software installed by default.
We encourage users to use one of our Linux systems for their appropriate tasks:
|Hostname||Operating System||Hardware||Architecture||Users with access|
||Ubuntu 20.04 Linux||Physical (formerly a VM)||x64 (amd64)||Academic|
||Ubuntu 20.04 Linux||Physical machines||x64 (amd64)||Research|
catan load balances between multiple servers.
That is why when you connect you will notice the hostname has a number, e.g.
The preferred remote access systems are
catan.eecis.udel.edu (research), and
These servers allow remote ssh access from off-campus. Other ECE/CIS
administered servers allow ssh connections from systems on
campus networks (including via the UD VPN).
Connections from other networks are blocked.
The remote-access hosts are shared systems, so the following policies are in effect:
No process on the remote access hosts may run for more than 100 cpu hours, after which it will be automatically killed. If you will need more than 100 cpu hours, you will need to restart your process.
Each remote-access system will be rebooted monthly so that security patches may take effect in a timely manner.
4 will be rebooted on the Monday following the first/second/third/fourth Friday of a month, respectively.
On each of these Fridays, the load balancer will stop forwarding new connections to the given machine.
go will be rebooted when needed as course loads permit.
EECIS hosts several servers & clusters specific to different research groups in the department. Should you need access to such a system, express permission is needed from the faculty member owning the system.
Our help desk is the place to ask for and/or grant these permissions.
