Two ISDN Lines - 8 Computers Help

By 845 ·
I have 8 computers that I need to hook up to two ISDN lines. I currently have one 16-port hub that they share. This hub is connected to our Novell network. These computers will be moving to a new building and they will not be connected to Novell. I pose the following questions;

1. How should I set the network or the computers up to work with each other?
2. Should I use MS file and print sharing to let them talk to each other?
3. How can I get all 8 computers to use the two ISDN lines?
4. They will have one printer to share between them; do I use file and print sharing for this also?

I?m looking for any tips or advice.

As far as the ISDN goes, you can "simply" buy an ISDN router (with 2 built-in NT1s). Configure this to load-balance between the 2 lines and hook it up to your hub.

To configure such a box, you will need a configuration generator appropriate for the box (e.g., ConfigMaker if you use a Cisco 1600 or 1700 series router).

Short answers.

1. Cat 5 cabling.
2. No. Have one server, and 8 clients.
3. Through the Linux box.
4. Linux (using Samba) will share it for you.

Long answers.

1. I would cable them all together the same as you would for a peer to peer network. I would not enable file and print sharing because as soon as people accidently delete files, they will have 7 scapegoats, legitimate or not. Noone should be able to screw up anyone elses computer.

2. If I was you, I'd use SMB (MS calls itMS networking) to connect to a single Linux server running Samba. Put in a large hard drive, and store everything on it. This will simplify backups, as well as administration. (Although it'll take a day or two to get Samba running how you want itrunning.) DO NOT forget a tape drive. Backups are paramount.

3. Use IP Masquerading to allow your 8 computers to access the internet through the Linux box. If you also run SQUID, you'll see a HUGE speed benefit to this as well. You'll want 2 network cards in your Linux box, one going to your local network, and one going to the ISDN lines. You could use 3 NICs if you wanted, that would allow you to have a seperate connection to each ISDN. You don't mention what they are used for, so I assume 1 NIC between the two would be fine... Do NOT forget about setting up IPTables (or ipchains) so you have a firewall.

4. Hang the printer off the Linux server, and it will also be shared through Samba. Most people will never know that SAMBA isn't NT server, except that it won't crash, and it'll be faster.

5. Although you don't mention it. I would suggest that you also price out a full MS solution. Recieve quotes so that they are official. When you finish installing everything with Linux (and buy a full copy of Red Hat 7.1 so you have support), total the cost (hardware and software). Present it to your manager when it's time for a raise. Between saving the cost of a 10 user NT license, and Proxy Server, you'll save several thousand. You will also save on your hardware, because 8 users will be fine for all of this on a P3 with 128 Megs of ram (get 512 Megs though, it's cheap) Also remember the tape drive, and more than enough disk space. One last suggestion, Run Linux on a server class box.

There are a few questions I could ask but I will make assumptions for the time being.

1. You will need a new hub to connect your 8 computers if any of the existing computers need to stay put.

2. MS file and print sharing works well for smallworkgroups such as this, but beware of the load it can place on the computer that might be designated the "file and print server". Setting up the file and print sharing is pretty simple from within the network neighborhood and my computer properties.

3. You will need a small router such as a Cisco 804 ( http://www.cisco.com/univercd/cc/td/doc/pcat/800.htm ). It isn't terribly complex to configure but having the configuration manager or a cisco knowledgeable helping hand is a plus. Knowing where this ISDN line will connect to is important, but we'll assume that it's either connecting back to your central location in which case you'll need another ISDN router. Or it's connecting to the internet in which case you'll need to contact your local ISP to obtain an ISDN speed connection. Make sure they support multi-link PPP so you can use both B channels at the same time.

4. File and print sharing both function very similarly within windows. But as with file sharing, print sharing can introduce a serious load on the hosting computer if multiple peer computers utilize the shared services simlutaneously.
