The "FIN bit with incorrect sequence number" problem appeared in some early 4.3 tapes. There is a fix for it, which I think has been circulated on comp.bugs.4bsd, and may be available for FTP from ucbarpa. If not, I have a copy (pub/fin_bug.43) on vax.ftp.com. If you don't have source, bitch at your vendor (the fix first circulated last summer). Depending on the vintage of your 4.3, there are a number of other bugs which appear in TCP output, or cause network-related crashes. I know of 9 of these, there may be more. There is another bug, which I just saw: The Van Jacobsen 4.3 code which was made public domain a few months ago sends ICMP Source Quench messages with random values in the "code" field. I asked a friend with source, and he says that the field is not initialized (it should always be 0). James VanBokkelen FTP Software Inc.

The unitialized code field for ICMP source quench goes back to the original 4.3, Van's code just inherited it.
