comment Why is Linux more popular than BSD?
Yes, absolutely there are many appliances based on BSD. The license is more favorable for that sort of application than the gpl. Easy examples include juniper routers and the trapeze wireless network controllers. In the embedded space, though, I do see lots and lots of linux based systems and I suspect that has to do with the RT kernel enhancements in linux. (see my original comment about fancy kernel enhancements in linux vs Xbsd)

comment Choosing network topology for top performance
I would switch over to 3 links between each of the devices in the primary path and 1 link to the secondary path.

If you're using spanning tree I believe all the traffic will follow one path through your network. You should to LACP between each of the switches, at the very least.

comment Choosing network topology for top performance
@gregc: How are you managing L2 redundancy? Are the clients on lots of different switches or are they split between the 2 switches the server is attached to? Are you using spanning tree?

I don't think in this case you'd ever be able to load balance across more than 2 links. You can't do LACP to 2 different remote switches, so you'd be doing 2 LACP groups and the server would only ever use one of those links at a time. I'd switch to a 3 and 1 and see if win2k3 allows you to bias to the 3 link LACP. Better performance in most situations and the system is still reliable if a single switch fails.

comment Running TFTP Server on specified port
does the client accept instructions that it connect on a different port? How hard would it be to update the client to use a different port? Changing the server's port is trivial -- it typically runs out of inetd/xinetd and can be told to start on any port you want.

comment Running TFTP Server on specified port
The trick is getting the client to connect to the tftp server on the non-standard port. It's either trivial or really really hard, depending on the level of stupidity of the client.

comment Are there any vendors making a Gigabit Fiber solution for laptops?
@romandas: Ethernet isn't like an old modem that varies the speed according to the available bandwidth. Ethernet works or it doesn't. If it doesn't you either get media errors which cause your throughput to fall through the floor or you don't get a link. If you get no errors with cat 5, you'll have the same bandwidth as if you use cat6. Bet you a beer on that one... Wish this silly interface had private messages...

That's the boring way to solve the problem! He'd need to make sure to get the proper sort of converter (multimode / single mode / etc)

@romandas: the gigabit ethernet spec requires that it function over cat5. Many older cat5 sites are not actually cat5 and still work at 100mb because it is more tolerant than gig, but if the wire plant tests out fine at cat5 specs, it will work at gig just as well as if you use cat6. networkworld.com/news/tech/2000/1016tech.html and en.wikipedia.org/wiki/Gigabit_Ethernet#1000BASE-T

laptop expresscards are 1 lane of pci express, which is 250MB/sec in each direction, which should allow you to snoop up to 2 flat out 1gig ethernet links. If you use a card that does IP in the card and allows you to put filters on the card, that should even allow useful monitoring of 10gig links, though clearly not the full pipe.
