Off Campus access¶
Important information about Off Campus access
Connecting to Talon3 is only possible if your computer is in the UNT network. Examples are computers connected to the UNT Campus LAN and Eaglenet/UNT Wi-Fi. If you are off campus, you may connect to Talon3 using the UNT Campus VPN. Connecting to the UNT VPN requires an active AMS UNT EUID. This is accomplished by installing the Cisco AnyConnect VPN Client. More information about installing the VPN Client can be found here and here.
Once you connect to the UNT VPN (located at
vpn.unt.edu) you can then access Talon via SSH terminal or the other ways to remotly connect.
In order to login to talon you will have to use SSH command on your personal computer’s temrinal:
When you account is first created, your password is your UNTID number by default and is only active for two days. You MUST login and change it by running the command
and enter in a new password. After this, your password will be active for 180 days. An email will be send a week before expiration as a reminder.
If you forget your password or it becomes expired, please consult SciComp-Support@unt.edu.
$ ssh firstname.lastname@example.org
Then it will ask for you password.
To make things easier you cna have it save the password and even create a shortcut so you can speed things up:
Setup alias on you SSH connection¶
Make sure you are in your home directory:
$ cd ~
Check if you have a folder names .ssh
$ ls -a
If you don’t you have to create one:
$ mkdir .ssh
$ vim ~/.ssh/config
Where t3 (it can be any word you want) is the shortcut you will use instead of typing:bash
$ ssh email@example.com
You will type:
$ ssh t3
Save SSH password¶
Now you have a shortcut, but you will still need to enter your password every time.
In order to save your passwords you will have to create a keygen file:
Enter file in which to save the key (/home/your_user/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/your_user/.ssh/id_rsa. Your public key has been saved in /home/you_user/.ssh/id_rsa.pub.
$ ssh-copy-id firstname.lastname@example.org
$ ssh-copy-id t3
Number of key(s) added: 1 Now try logging into the machine, with: "ssh 't3'" and check to make sure that only the key(s) you wanted were added.
Congratulations! Now every time you need to login to Talon you just need to type ssh t3 and your good to go!
When you want to copy files using SCP¶
If you are not familiar with SCP you can find a nice example here
Now since you setup your ssh shortcut to be t3 and the password saved, when you use SCP it will be a lot easier!
scp path/to/file/my_file t3:.
