Everthing seems to normal. (I didn't try to set 'half-duplex' mode though.) rev. 1.27: - auto-negotiation fails and I always see somthing like: "hme0: invalid packet size 8192; dropping" - "ifconfig hme0 media 100baseTX mediaopt full-duplex" corrects the negotiation problem only.(The switch is Intel Express 460T and the link was fixed to full-duplex in the switch menu.) - When I try to send files with ftp I see the following message in ftp client. "425 Can't create data socket (xxx.xxx.xxx.xxx,20): Can't assign requested address." (Because ssh works well, I guess it is related with bind problem with hme's IP address. As you know, ssh binds with INADDR_ANY. I wonder how this can happen and have no idea. :-( ) But when I set to "half-duplex"(i.e. without setting mediaopt in rc.conf file), sending files via ftp are ok. I guess there is another problem with ifconfig mediaopt command in addition to lack of auto-negotiation. The only way I can make hme work correctly was to patch the source and revive the commented code in order not to invoke ifconfig mediaopt command. However, the method I taken has a problem too. When the system boots hme(4)'s auto-negotiation seems to take a quite long time. So I see "no carrier" message during the boot and my ntp configuration doesn't work. But after a few seconds later, all seems to work ok incling ftp transfers. Regards, Pyun YongHyeon -- Pyun YongHyeon <http://www.kr.freebsd.org/~yongari>
