I have a Slackware 10.2 box routing internet from ppp0 to eth1, both are 100 meg NICs. I HAD eth1 plugged into a 10/100 hub which had an AirPort Express and then my iBook G4 (with 802.11 g) connecting. I would often get throughput (with `scp`) from my iBook to my Slack router of 250 kbp/s.
I've been having problems with my AirPort dropping out for an insofar undiagnosed reason (maybe overheating?) I decided to can my AirPort for the time being, hoping to get better throughput just plugging the two NICs together.
Now I only get a maximum throughput, with 2 less hops, of 40 k! Any ideas what's caused this crazyness?
(No it's not a crossover cable, but AFAIK iBook G4 NICs auto-detect. I do connected, it's just slow; a crossover cable problem should present the main symptom of not linking at all, not slow throughput).
I also have my firewall set up with the following additional rule (bad MAC is intentional for posting):
Code:
/usr/sbin/iptables -I INPUT -m mac --mac-source kk:kk:kk:kk:kk:kk -i eth1 -j ACCEPT
Which has done nothing.
I did notice a burst or two of 120 k, but nothing sustained.
