Getting started

How to log on to the computers from your PC / Macintosh / UNIX / Linux

Before logging on to one of the UPPMAX systems, you need to belong to one of the UPPMAX projects and have an account on one of the UPPMAX systems. You also need to log in from a computer with proper DNS name and have a working forward and backward name resolution.

Access to all systems are through the use of the secure shell.

Windows

Any windows ssh-client which supports the ssh2 protocol can be used. A good, free client is Putty which can be downloaded from its primary web-site: http://www.chiark.greenend.org.uk/~sgtatham/putty/

When putty is started it will display a window where one required line of input is "Host Name (or IP address)". The Host Name is one of the hostnames of the UPPMAX system (listed at the bottom of this page). The protocol radio-button should be set to "SSH". After clicking "Open" at the bottom of the window, Putty will display a dialog-box the very first time you log on to one of the UPPMAX systems, due to that Putty does not yet know about this computer system. Typically you will want to answer yes to this dialog. Following this, Putty will ask you to type your assigned username at the "login:" prompt and finally will ask you for your password. Should this not succeed, you can try again, look at the FAQ  section, or contact support@uppmax.uu.se.

Macintosh

Open the Macintosh OS X Terminal (in Applications: Utilities) and log on as you would on any UNIX system, typing "ssh user@kalkyl.uppmax.uu.se" on the command line, see UNIX/Linux below for details.

UNIX/Linux

Secure shell clients are typically available or can be installed on UNIX/Linux systems. Ask your system admininstrator for help with this if it so happens that it is not already installed.

For example to log on to Isis, type "ssh kalkyl.uppmax.uu.se" at your command prompt. The first time you log on, you will get a question whether you're sure you want to connect, since ssh doesn't know of the identity of the UPPMAX system yet. This is normal, so you will typically want to answer yes to this question.

Example session:

some-computer: ~> ssh kalkyl.uppmax.uu.se -l user
The authenticity of host 'kalkyl1.uppmax.uu.se (IP 130.238.136.97)' can't be established. 
RSA key fingerprint is xx:xx:xx:xx:xx:xx.....
Are you sure you wan't to continue connecting (yes/no): yes
Warning: permanently added isis.uppmax.uu.se (RSA) to the list of known hosts.
user@kalkyl.uppmax.uu.se's password:
