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

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. There are a couple of very serious bugs in TCP that is fixed in this release which is why I really encourage people to upgrade. (They do not happen often, but if they happen, they have a high chance of crashing the system.) Highlights: - Stability and reliability improvements in TCP. - Improved HTTPD - Improved MAILD Magica.Update.UU.SE, which is a real PDP-11/70, have now run with the latest release for over 3 weeks without any issues, so I think it's safe to say that this product is now very stable. Mim.Update.UU.SE (an emulated 11/74) have in the same time served over 7Gb of data over FTP, HTTP and other lower volume channels. (And both of these machines are more or less fully exposed to the internet, so they see a *lot* of connections and random attempts to compromise them all the time.) Detailed information on things that have been done since the last release: TCP: - Improved handling of received TCP push packets. - Improved TCP ACK handling under lost packet recovery. - Improved TCP window update handling. - Bugfix for the condition that a socket was closed while there was outstanding sends and the remaining window was 0 and the transmission was not ACKed. This would cause the socket to get stuck in a pending state. - Improved TCP write handling. The second IOSB word was previously not set to reflect how much data was written. - Added new TCP option for sockets to optionally return available data at read if push was set. - Bugfix in TCP. An internal data structure was sometimes modified when it should not be, which could cause a system crash under rare circumstances. HTTPD: - Improved error handling for CGI pages. - Improved subprocess handling for CGI module. MAILD: - Improved MAILD to handle broken Linux MAIL11 server. - Improved MAILD error handling. - Bugfix in MAIL. When composing mails, the temporary file is now created under SYS$LOGIN. - Added timeouts for various parts of MAIL11 processing. Libraries: - Improved subprocess handling in BASIC+2 library. - Updated F77 library and documentation. Multinet: - Improved performance. 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 Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
