Hi, Mr Konzack, Thank you very much for your time and guidance.
In fact, our cabling is in poor condition, right now, so we're budgeting to replace all of it soon, with a new CAT6 harness. I'll arrange to replace also the switches - that will allow us to move to GB ethernet in the workstations at the end of current leasing period (next year). However, our uplink to the the server room is a single 1GB fiber link. Actually, there are two links, but that's only for redundancy, it's not trunking. There are about 20 users, 10 of which are tipical windows office users - mostly local data and processing, network only for web, e-mail and printing. The remaining users are doing debian etch, including remote home and a lot of ssh -XC sessions. Do you think that only one link will be enough?
