After installing FreeBSD 7.1 RC1 from the DVD-image I found that the
PC in question has no LAN connectivity upon reboot.
The PC has an Intel GE builtin NIC showing up as "Intel PRO/1000
Network Connection 6.9.6" in dmesg.
For the problem: Though IP-Adress, default-GW etc. are correctly set
the box can't e.g. ping anything on the net; neither on the local lan
nor across the default-gw. Same the other way round: machine can't be
ping-ed, not even from the local subnet.
What's interesting though is that on both the LAN-Switch and the PC
("ifconfig") the interface shows up as connected. Even more
interesting: the MAC-address of the PC-nic shows up on the
corresponding LAN-Switch. So there definitely is "some form of
When starting a "tcpdump" there's no output - so obviously nothing is
coming into the machine form the network.
To cross-check I've
a) swapped the patch-cable for another one - no change
b) tried Ubuntu (Linux) from the Live-CD - under Ubuntu I've got full
LAN-connectivity without any problems
so it must be something FreeBSD related...
Has anybody out there had problems with an Intel GE-Nic ("em0") under
Thanks in advance for any clue,
