Some diffs to fix the problem are at the end of the message.
|
||||
For the net/tcp directory, you should probably get it from nic.funet.fi
|
||||
Linux/testing/beta/NET, as it's very big.

All the clients and servers are from BIND. The only kernel
|
||||
code that is remotely related to anything is the wd8003 driver. I used
|
||||
the 386bsd driver as an example when I wrote the code. But basically
|
||||
everything is different. The basic tcp/ip code was written completely
|
||||
by me. The only thing I've gotten from anyone else is some icmp code
|
||||
which is probably not from net2, as it has to interface with everything
|
||||
I did which is not remotely like anything in net2 (Actually I don't know
|
||||
this since I haven't look at the net2 code, but the way the tcp/ip code
|
||||
evolved it couldn't be like anything else.)
|
||||
|
||||
Everyone Please note at the end of this message are some diffs which must
|
||||
be applied for unix domain sockets to work (after applying my sock.diff
|
||||
which screws them up.)

||||

||||

ps. I'm using X right now, so the diffs work.
