Strange problem with TCP checksum

Hello, I have a weird network problem which I believe may be caused by the FreeBSD igb driver or perhaps even the network adapter. Let me try to explain the scenario in brief: I have a FreeBSD 10.0-RELEASE-p10 server with a public IP address, in which N virtual machines are installed through JAI

May be ypotr switch try to negotiate spanning tree ? I have same problems with other cards, not only sk. Try to disavle spanning tree negotiation on your switch. On cisco Catalyst this is done by 'spanning-tree porfast' command on interface -- С уважением, Vladimir

Strange problem with sk0

Hello! I have a rather bizarre problem with my on-board sk interface... It only works, when tcpdump is running... Seriously. It negotiates with the switch (1000baseT/full-duplex) just fine, but, unless tcpdump has it open (and in "promiscuous" mode), no traffic seems to go through. It would

Strange problem with IPSEC, not entirely transparent.

I recently set up IPSEC communications between two hosts I have in different places. One is FreeBSD 5.4-STABLE August 22. 2005. The other is 4.11-STABLE April 18th 2005. I run a gif tunnel between them and routes for networks found on both sides are negotiated by quagga using ospf. the internet

Strange problem with PPP/Netgraph (PPPoE)

I've got a bunch of FreeBSD 4.4 boxes doing PPPoE using netgraph and PPP. They've been doing this quite happily for a few months, but now one of the boxes is sick. [ Disclaimer: I'm 150 miles away from the box, so I don't have exact log messages. What you see below is my simple paraphrasing.
