>Description:
Intel EtherExpress Pro/10 does'n work on last month, on last 4 cvsup
and make world (it was over than one year that works. It is well
configured. The cable (RG58) is ok and correctly terminated. On the
same machine win*** can use tcp/ip to connect to my Amiga.
I cannot ping/telnet/ftp neither to nor from FreeBSD. I tryed with
tcpdump to follow what happens and noticed that nothing but arp go
bidirectional (tcpdump does not see any packets coming from Amiga but
send and receive arp requests, gotting also mac-address of Amiga side)
My network:
; 192.168.22.1 tip # Amiga
; 192.168.22.2 tap # Amiga
; 192.168.22.3 trudy # FreeBSD/Win*** dual boot
# netstat -rn

As you can see only ARP WHO-HAS packets runs on my network and after
ping (or telnet/ftp, no matter) mac-address of Amiga-side shows on
routing tables of FreeBSD-side.
Kernel configuration follows:
# Network card (Intel EtherExpress Pro/10)
device ex0 at isa? port 0x300 irq 10
Boot messages shows NIC configured:
ex0 at port 0x300 irq 10 on isa0
ex0: Intel EtherExpress Pro/10, address 00:aa:00:ad:44:7c, connector TPE
Ifconfig show board up and running:
# ifconfig ex0
ex0: flags=c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX> mtu 1500
inet 192.168.22.3 netmask 0xffffff00 broadcast 192.168.22.255
ether 00:aa:00:ad:44:7c
I am not using TPE but BNC, but I don't think this is the problem
because how ARP can reach other side if the problem was the wrong
connector? BTW: the board is forced with dos-boot-floppy to be _NO_
plug-and-play, _STAY_ on irq#10 and on I/O 0x300, connector auto-swith.
I tryed also with an hub for TPE a couple of hour with the same results:
no ping, no telnet, to ftp, only arp using FreeBSD 4.0-CURRENT, correct
operation even with TPE using win*** :-(
>How-To-Repeat:
Buy an Intel EtherExpress Pro/10, install it on a 4.0-CURRENT :-(
>Fix:
Install 3.3-STABLE, 3.4-RC. With those release (on another machine)
no problems found with the same NIC.
