SSH access

What is it?

You can use shell on the LTS server, connecting to it by SSH (Secure Shell) procotol. This way you can work on the server almost like it's your own computer. It has many advantages, most importantly that wherever you connect, you always use the same account.

During a first connection your client will give you key's fingerprint of server you're connecting to. To rule out man in the middle attack, verify given fingerprint with fingerprints list of faculty's servers.

From Linux

On Linux most of the time ssh program is installed by default. Therefore to connect with LTS, it is sufficient to write:


Where s123456 is your login.

If you're connecting for the first time, program will ask to accept server's identification.

After that standard credentials input, welcome message and command prompt will appear - you're ready to work on a server.

Automatic authentication without providing a password

Thanks to Kerberos protocol, logging in from laboratories' computers does not require password.


Just like on Linux, Windows 10 has ssh installed. To connect to the LTS server, use the same command in CMD:


Earlier versions of Windows do not come with preinstalled SSH client. Therefore, we recommend to use popular program PuTTY, which is also available on Windows in laboratories.

After its startup it is enough to enter server address:, select SSH protocol (port 22) and accept.

Like on Linux, on a first connection program will ask about acceptation of server's identicifation. Afterwards, black window for credentials input will appear.

What's next?

After that it's just like on every other Linux. If you'd like to learn basics of this system, we recommend enrolling on "Operating Systems" subject or checking resources which our University's Services offers.
