h1. Using a RALF workstation

RALF stations are available at ISAE-Supaero

h2. Login, home and privileges

You must login using your ISAE-Supaero account. Once the access is granted by the LDAP server, a home directory is automatically created locally in subdirectories of @/home@. Notice that networks shares are not available through NFS due to delegated administration of the computers. However, it remains possible to use network shares through SAMBA (use for example Gigolo).

h2. Setting up the proxy

In a GNU/Linux shell, the ISAE's proxy can be configured mainly through @http_proxy@ and @https_proxy@ environment variables.

<pre>

export http_proxy=http://host:port

export https_proxy=http://host:port

</pre>

The fields @host@ and @port@ are not released publicly, do not hesitate to ask to the professor in charge.

In a Firefox web browser, go to "Edit -> Preferences -> Advanced -> Network -> Autodetect proxy".

h2. Getting privileges

Users can obtain advanced permissions by belonging to appropriate groups:

* for realtime scheduling (in order to execute UHD), users should be member of @usrp@ group;

* for administrator rights (through sudo), users should be member of @sudo@ group.

For the cases above, adding an user to a group can be performed thanks to the following instruction (as root):

<pre>

adduser <user> <group>

</pre>
