I am a "mere user" of a Novell LAN and I would like to ask a few questions to protect myself from the forces of evil (i.e. SA) that tell me that "it cannot be done." I apologize if this is the wrong place to post these questions and would appreciate some direction to the right place. We are running Novell Netware 2.12 Rev B with an ethernet, I think mostly 3Com 3c501 cards. 1. Is it possible to control access to printers on the LAN so that only certain people can get access to certain printers? 2. Is it possible to have a log made of each use of a printer? 3. What are the virtues/problems of making a bridge vs. connecting all the machines into one big LAN? Doesn't a bridge just make one big LAN with more performance problems? 4. If there is a bridge, then it should be possible to get access to any printer on EITHER network, right? 5. Is there any problem with mixing different ethernet cards in a Novell LAN. The SA claims that we cannot use different cards on the same LAN. Many thanks for your help. Seth Chaiklin chaiklin@cunixf.cc.columbia.edu seth@ny-yn.UUCP

Set up their print queues in the login scripts and take away printer commands, such as printcon, so that a user cannot add/change. > 2. Is it possible to have a log made of each use of a printer? Well, without programming (capturing the print interrupt at the user workstation) it is somewhat difficult. Some print software (3rd Party) contain this feature. If you are using vanilla Netware, you can assign a dummy print queue along with the real one. This way, the print data get stored at the phantom queue for you to browse with the Pconsole command. Just keep in mind that a undrain queue can built up pretty fast. > 3.

Well, this depends on the topological design in your installation. For one thing, there are limits on how far an node can be away from the server (this depends on the medium used, ie.- Thick or thin coax, twisted pair, fiber, etc.) Going across a local bridge (remote bridge means a modem arrangement) does post some performance degradation, but if design properly you should get the same or better performance than one huge LAN (for one, eliminates collission and wait time for transmission). > 4.

The default server is the one you logged-in or attached to (via a "login servername/userid" or the ATTACH command). > 5. Is there any problem with mixing different ethernet cards > in a Novell LAN.

A bridge gives you 2 different nets. A repeater or router will also do the job, although they pass everything, not just packets for the particular net. > 4.

The only problem I have is with the 16bit ISOLan cards in a fast (386SX @16Mhx) server, where the 3c501's can't keep up and die. > Many thanks for your help. > No problem! > Seth Chaiklin > > chaiklin@cunixf.cc.columbia.edu > seth@ny-yn.UUCP -- ============================================================================== | Hamish Marson | Internet hamish@waikato.ac.nz | | Computer Support Person | Phone (071)562889 xt 8181 | | Computer Science Department | Amiga 3000 for ME! | | University of Waikato | | ============================================================================== |Disclaimer: Anything said in this message is the personal opinion of the | | finger hitting the keyboard & doesn't represent my employers | | opinion in any way.

All thin-net manufacturer's boards support cable lengths of at least 600ft(IEEE spec). Many manufacturers have pushed that length to 900ft. As I said it's a small difference.

Although many vendor Ethernet Cards *CAN* work together, as a campus network administrator, I have to defend this guy's SA. In order to keep some sanity, the fewer types of cards I have connected the better I can support the users.
