Edubuntu in an existing network

[Kory Mohr]

FWIW, I've been making use of No Machines instead of VNC running on the server.  They offer a free version although it's limited to two connections.  Works very well for quick remote access from a Windows client.  It's extremely secure and the environment is exactly what you'd see when logging in to a client.

On a similar note to François' firewall/DHCP settings, we're using a Sonicwall Pro 3060 running Enhanced.  We've successfully set the SW unit up with LDAP authentication against our Active Directory domain.  Students are offered a restricted level of web access based on times of day and content and fac/staff are offered another level of access.

I'm finding, however, that the authentication only works on the Edubuntu server when one person access the web.  For example, if I access the web using Firefox on an Edubuntu client, I'm prompted to authenticate.  If another client comes online and access the web, I'm not prompted to authenticate because the first client already did.  So, I'm receiving their access rights.

What I'm planning to do is keep up a permanent No Machines connection from a workstation that sits in my office with a student-level web access account.  That way whenever students log on up on the lab, they always have the student-level access.

Not a good way to do this, but it's what I have thus far.  I've been working with the Sonicwall in adding the Edubuntu DHCP subnet to it's access object group but it's just not taking that subnet (probably because it's not serving the IP address to the clients; the Edubuntu server is.)

Anyway, just brainstorming and continuing to enjoy following the threads posted here.  :-)

Kory
