Working on the servers of the ESCER Centre

Firewall

To protect our servers and data we have a firewall installed around all of them. To get inside this firewall you need to either:

• beconnected via cable on the internet on the 6st or 7th floor of the PK
• use UQAM's VPN
• connect to one of our hoppies - see "External servers" below.

External servers

The so called "external" servers are outside our firewall and are only used to connect to our internal servers when connecting from outside the firewall. You can find their names here : external servers

Internal servers

We call them "internal" because they are inside our firewall. 

To access your/our data you need to be on one of our "internal servers". Even though each user has access to all of our servers, please, use the server "assigned" to your professor. The name of the server you should use is also written in the email you received about your account. If one day you switch professors, please, let me (winger.katja@uqam.ca) know!

Check out our full internal server pool under : Internal servers

Also, have a look at the graphic on the following site that visualizes all of the above : Computer infrastructure of the ESCER Centre

Operating system 

The operating system on our servers is Linux. If you are not familiar with Linux/UNIX have a look a the basic commands: Basic Linux/UNIX commands

Connection to internal servers

When using a workstation or laptop in an office on the 6st or 7th floor in the PK, which is connected to the internet via cable, you can connect to our internal servers directly. Otherwise you will have to connect via a VPN or via one of our external servers hoppy1/hoppy2/hoppy3.
To learn more about how to connect to our servers check out the following wiki page :  Connexion à nos serveurs

Change password

To change your password, follow the instructions on our wiki page:        Change password

Your home

On all of our internal servers you have the same home called: /HOME/username
For your home you have a quota of 500 MByte.
Everything under the home directories is backed up. You can find more information about our backup policies and how to retrieve the backups on the following wiki:        Home backup
Since the homes are backed up it is highly recommended to keep everything that is small and important under your home, like all your scripts and programs! You can work with symbolic links if you like to have your scripts and programs accessible from other directories or on other file systems. You can find a short info about the links command here : LinkFiles

Your data

To store your data you have disk space available on a filesystem on one of our internal servers. You find the names in the email you got about your account creation.

Data backup

As said above, everything under the home is backed up. But by default, non of the data under the "data space" are backed up. However, you can get up to 1 TB of your data automatically backed up once a week by following the instructions on the following page: Data backup

Data transfer

If ever you need to transfer data from/to one of the internal servers to/from the outside, follow the instructions on the following page:   Transfert de données de/vers l'extérieur
