The switch isn't supposed to know anything about DHCP. If I am reading Nadav's original post correctly, the request get to the server, and the server sends a response, but the switch does not forward the response to the Linux box. > what happens if you hardwire the addresses? A similar problem with ARP has been mentioned. It sounds like there is a problem either with LDP (link discovery protocol) or with STP (spanning tree protocol) or MAC table implementation or something. These things are standardized to the umpteenth degree, the chances that there is something intentionally breaking Linux are minuscule, IMHO... While a HW problem cannot be excluded I'd trust Nadav to have swapped cables and ports around, etc. I understand also that the NIC works fine in a different topology - even when connected to a bus/hub the peers have to keep MAC tables, etc., and they understand whan the NIC is sending. Nadav, if you are willing to "splurge" for a different switch (maybe you can borrow one to test?), and it fixes the problem, then I'd say write it down to Edimax over Geoff's objections ;-) and forget about it. If it happens with a different switch, then it will become really interesting (and maybe borrowing another NIC from someone will be in order?). -- Oleg Goldshmidt | o...@goldshmidt.org _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
