Network optimization?

2001-09-26 Thread Kris Kirby
Please, if I have addressed this wrong, do not hesitate to point me toward another list. I'm looking for tips on network / kernel optimization. I know that when 100Mb/s ethernet first came to FreeBSD, there were P90s moving at 9MB/s, but I've never been able to break 7MB/s, except for my K7-850

Alteon gigE NIC (if_ti driver) problems

I have some more information since my initial posting yesterday. I set the NMBCLUSTERS back to default, which made no difference. Therefore, moving from 4.3 to 4.4 is what drastically increased the frequency at which the link goes down and back up. I also captured dmesg now I case there is any use

>From what I've seen in this list, this seems to be the best performing gigabit ethernet card on FreeBSD. Most stores now stock the newer 3c985B-SX rather then the 3c985-SX. Does the existing driver handle the newer "b" card as well as the old card? I just want to make sure before I go orderi

Re: Win32 to FreeBSD VPN

2001-09-26 Thread Mike Tancsa
For the server size, use mpd on FreeBSD. It works very well. For client side, best to stick with PPTP if you are using anything less than win2k. I am not aware of any free IPSec clients for Windows that work well on all platforms. Even the built in VPN client on MS will require quite a few know
