for the prompt replies. The problem was solved by disabling auto detection
and forcing the card into 10mbit/sec half duplex mode.

Many of you suggested firing the entire IT department responsible for this
debacle, which is indeed an attractive option :) Our company is growing
fast, so they leased some temporary office space next door to our main
offices... For some reason, despite having 3 weeks to prepare the space, we
are stuck with Cat3 wiring and ports that weren't activated. I'll stop the
rant here.

Directions on forcing the interface into half duplex/10mbit mode are easy to
find in the archives, but since some of you were kind enough to summarize it
for me I'll include them (quoted from Christopher's email).

ndd -set /dev/hme instance 0 <-- this line first. set which device.
ndd -set /dev/hme adv_autoneg_cap 0 <-- autonegotiation
ndd -set /dev/hme adv_10hdx_cap 1 <-- 10/half
ndd -set /dev/hme adv_10fdx_cap 0 <-- 10/full
ndd -set /dev/hme adv_100hdx_cap 0 <-- 100/half
ndd -set /dev/hme adv_100fdx_cap 0 <-- 100/full

I made these settings relatively permanent by adding lines to /etc/system to
the effect of:

set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_10hdx_cap=1
etc, etc, etc....

Thanks again!

Subject: new building -- cat3 wiring, network startup problems

Greetings Gurus,

We moved into a new building and the E450 I'm taking care of is having
problems getting on the network. IT tells me the building wiring is all cat
3, though I would've assumed the NIC would be able to auto detect....

What can I do to get the interface up? What information can I provide to
help troubleshoot?
