Connecting to other computers (or clusters, etc.) involves a command called
ssh.
It stands for “secure shell,” and allows for secure remote access to other
devices. This is helpful.
Oftentimes, there are people much smarter than me that want to heavily protect their computers. Universities are one example. They create strong firewalls to protect information, which means that a special way to remote access computers must be used, and that way is through VPN. VPN stands for “virtual private network,” and extends the private network over the public sphere for those allowed access. For those affiliated with the University of North Texas (UNT), the easiest thing is to download Cisco AnyConnect. More information on how to download Cisco AnyConnect for UNT students is available at: UNT ITS
Once installed and connected, accessing computers, clusters, and systems on the
UNT network is possible.
The VPN address for UNT is vpn.unt.edu, and the login is the same as your
UNT email login.
After connection, the command
$ ssh username@ipaddress.or.title
is used to access the device.
For instance, if someone regularly logs in as euid123 and the computer’s
network address is talon3.hpc.unt.edu, then their ssh line would be:
$ ssh euid123@talon3.hpc.unt.edu
