Hello

There is about 30 Linux clients in our network and I need to setup Linux server with file sharing services.

How can I achieve behavior listed below?
1. Computer boots up and show login/password dialog (kdm).
2. User passes remote authorization.
3. User home directory mounts (so user has his own home and desktop directories at the server).
4. Some script runs with user privileges.
5. Display manager starts.
6. (Optional). Firefox uses data from step 2 to authorize himself to squid.

Thank you,
Anton

i think this may have some of the answers you are looking for..

the last one, using ff and squid is pretty much the same as windows, addressing the squid proxy to gain outside access..

Thank you

But I can't use Active Directory. I want to setup network without Windows at all.
Also, I need firefox to be able authorize himself to squid using login/password entered at log-on screen.

LTSP is the answer. Low cost, high reliability. You can spend good money on server, because diskless workstations are dirt cheap.

I really love LTSP and use it in some circumstances (It's cool to use my native Linux environment remotely). But I have already a set of powerful computers, so LTSP is not applicable.

Why Samba+PDC is a very simple solution in a Windows world, but I can't find any solution under Linux? Even NFSv4+Kerberos isn't best option because it is not able to work with multiple network interfaces on the same machine (http://wiki.linux-nfs.org/wiki/index...r_doc_kerberos).

Don't know then. Server+Terminals is historically UNIX networking model, when HDD was expensive. Nowadays HDD's are cheaper but still cost money, plus they are most unreliable part of the computer. With LTSP you can have real heavy-duty server, h/w RAID plus good backup solution, ensuring your data is safe. And it won't cost a fortune. Old cheap P2 and P3 computers serve well as terminals. Overall cost is lower than in Windows-type network, reliability is at least a magnitude higher.
But you say your hardware is incompatible ... multiple NIC's ? Why?
Sorry, can't help, wish you good luck.
