[HECnet] Announcing TCP/IP for RSX-11M-PLUS

[Johnny Billquist]

Time for a new release announcement of TCP/IP for RSX-11M-PLUS.

This release contains a lot of fixes and improvements in many areas. I 
really encourage people to upgrade, as some of these changes can have a 
noticeable impact on stability.


Highlights:

- Distribution now includes the PDP-11 C and BASIC+2 resident libraries,
so that various tools and utilities that are built against them can
be installed even if the full language is not installed on a system.
- Improved stability.


Detailed information on things that have been done since the last release:


Ethernet driver:
- The ethernet driver could under some overload situations become deaf, 
and not receive any more packets.


TCP:
- TCP FIN handling. Under some circumstances, TCP could get into a state 
where both sides would be sending FIN packets, and not acknowledging the 
other sides FIN.
- TCP sequence handling. Under some circumstances, TCP packets with bad 
sequence numbers could be accepted as valid packets.
- IO.KIL function for normal TCP ports removed. It turned out that it 
was very undesirable to process IO.KIL for connected sockets. (A 
separate function with the same effect does exist.)
- Added counted for rejected TCP SYN packets.
- Improved task activation code for TCP daemons.


HTTP:
- Improved logging.


MAILD:
- Improved new mail notification handling.
- Correct handling of EHLO/HELO for SMTP.
- Implemented proper MAIL11 protocol, version 3.
- Rewritten address rewrite logic to better process both SMTP and MAIL11 
addresses.


MAIL:
- Simple mail client now exist.


Libraries:
- Unified user lookup functions. User lookups now happen both on 
lastname, UIC, SID and login directory. This is used both by MAIL, FTP 
and HTTP.


As usual, the distribution is available from:
ftp://mim.update.uu.se/bqtcp.dsk
ftp://mim.update.uu.se/bqtcp.tap
ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk

The documentation is also available through ftp on Mim, or also at 
http://mim.update.uu.se/tcpipdoc

The firewall for Mim have now been removed, so no need for the alternate 
ports, but Mim is still listening to the alternate ports as well.
ftp: 10021
telnet: 10023
