Does not work on beige G3
Authored by: kopf on Mar 28, '03 10:48:01PM

I've tried the command from this article as well as the full Startup Item script from Apple's KB article and it doesn't work on my beige G3 (with the built-in 10BT Ethernet port).

> sudo ifconfig en0 media 10baseT/UTP mediaopt full-duplex

SIOCSIFMEDIA: Operation not supported

Anyone know a solution?

(Mac OS X 10.2.4, G4 upgrade)

Thanks.

Seems pretty clear that a Beige G3 must not support full-duplex Ethernet.

ummm, actually, it has to do with the autoselect feature... I'm getting the same error :
root# sudo ifconfig en0 media 10baset/UTP mediaopt half-duplex
ifconfig: SIOCSIFMEDIA: Operation not supported

When I connect directly to my dsl modem(10T), my NIC switches to 10baseT/UTP (half-duplex), but when I connect to my netgear router(which is then connected to the dsl modem of course), it switches to 100baseT, this causes an extreme bottleneck (1.2k/s!!) when users try and access my ftp server on port 21.. I'm on a 333b imac... so the nic is capable of both duplex modes, and many more... but the force commands in the terminal will not take, and I get that error.. I tried the apple tech doc way of doing it, but alas it's not working. I'm wondering if I should put a 10T hub between my puter and router to force the 10T connection. Or perhaps a CAT-3 cable to force the issue.??
