The current [[ARMv8]] AArch64 server system is known as '''betty''' (or '''bbetty'''). This system is located inside the [[EHL]]. To connect to this system, you need to connect through the EHL gateway on port 2201.

Our x86_64 server is known as '''xerxes'''. To connect to it This system is located outside the [[EHL]] but is accessed through the EHL gateway from within outside Seneca, issue this command:using port 2202.

If you're using a command-line ssh ''username''@xerxes.internal.cdot.systemssystem, and you are on the Seneca network, you can issue a command such as this:

You ssh -p 2202 ''username''@ehl.internal.cdot.systems Or you can't yet connect to directly:  ssh xerxes .internal.cdot.systems To connect from outside Seneca, so connect to a system inside Seneca first and then use the command above:  ssh -p 2201 ''username''@ehl. Check back to this page to find out if/when external access is availablecdot.systems

If you're using OpenSSH (the ssh client used on most Linux systems and other platforms), you can simplify complex ssh command lines by placing host connection details in the file ~/.ssh/config. For example, to access aarchie from outside Seneca, you could add this entry:

hostname "ehl.cdot.systems" user "jdoechris" port 2201 Host "betty-internal" hostname "ehl.internal.cdot.systems" user "chris" port 2201 Host "xerxes" hostname "ehl.cdot.systems" user "chris" port 2202 Host "xerxes-internal" hostname "ehl.internal.cdot.systems" user "chris" port 2202 Then you can use these commands to access betty and xerxes from outside of Seneca:  ssh betty ssh xerxes

And then you could Or these commands to access aarchie by simply typingbetty and xerxes from inside Seneca:

ssh aarchiebetty-internal ssh xerxes-internal
