I am currently running coLinux configured in "ndis-bridged" networking mode, on a machine whose wireless networking card or driver seems incapable or unwilling to accept non-broadcast layer 2 traffic, or traffic not destined for the wireless card's primary MAC address.
After figuring out this was the problem, I tried configuring the coLinux interface to have the same MAC address as the host machine. Magically, networking started to function. Unfortunately only a single problem remains: the host machine cannot talk to the coLinux instance, even though the rest of the LAN can.
I figured out that by adding a static ARP entry to the host for the coLinux instance's IP address(es), I could accomplish full connectivity in bridged mode, even though the wireless card/driver didn't want to play along.
Despite the hackishness of this setup, I would like to keep it for a few reasons, primarily of which is IO performance for the coLinux instance. This brings me to a problem: persisting the ARP entries on the host machine.
I have searched the web, but have been unable to find the WinNT equivalent of
/etc/arp from UNIX. Does such a file exist? I suspected somewhere in the registry, but alas, my searches thus far have been fruitless.
My only alternative is to run a batch file at startup to recreate the ARP entries using the
arp command line tool, but this, ironically, seems hackish. :)
