Gentlepeople,
I've added a map maker to PyDECnet, which is now on-line on HECnet. It currently refreshes once every 24 hours, showing locations and paths between the locations. You can hover over the location markers to see nodes that have been recently observed, or click on the markers to see all nodes whether observed or not. Clicking on the connecting arcs will tell you which nodes have connections on that path.
The map is here: http://akdesign.dyndns.org:8080/map
You can also see a tabular display of the data collected by the network scanner, at http://akdesign.dyndns.org:8080/map/data . Right now that link isn't shown, I'll add that.
Feedback would be welcome. There is no map legend yet. The button on the upper right is the "layers" tool that lets you chose among a number of map sources, and lets you turn the location and/or path information on or off.
The default map is OpenStreetMap, and the mapping interface machinery is the Leaflet package, a very nice and easy to use tool.

You can park all other area 59 nodes at the Stockholm address.

I've run into a glitch with the map maker, which wants to make NICE connections to other nodes without authentication information. Depending on the OS, there is a notion of "default account" or "proxy", and I expected that to work when I send the connect request off without any username/password content.
Apparently that's wrong for VMS, and I very vaguely remember this but not what to do about it. On VMS, how can you set up a network object to allow access without a password? If you do this, what is required in the connect request coming in?

Time for a new release announcement of TCP/IP for RSX-11M-PLUS.
Highlights:
. IP multicasting have been implemented
. TCP stability improvements
Detailed information on things that have been done since the last release:
IP:
. Added IP multicast support, and functions to enable this on UDP sockets.
UDP:
. Added functions for joining and leaving multicast groups on sockets.
TCP:
. Bugfix in TCP. Under some circumstances, TCP will stop receiving data
because of a calculation error on TCP sequence numbers.
. Improvement in TCP. Code accidentally sent unnecessary probes when a
socket is in Close Wait.
. Bugfix in TCP. Any ICMP error received for a socket caused the TCP
connection to close down. This should not happen for ICMP source quench
or ICMP timeout messages.
. Correct MSS computation and setup based on interface MTU.
IFCONFIG:
. Added ability to change MTU of interface in IFCONFIG.
FTPD:
. Bugfix in FTPD. Long home directory names caused FTPD to fail.
Some additional notes:
Some people might wonder why the multicast changes have been introduced,
but no other changes related to it. I wanted to get this change out now
in order to allow people the possibility to play with it, if anyone is
interested. For my own part, I next plan to look at mDNS, to allow RSX
to live in home networks without a proper DNS server, but still be
visible to other systems. mDNS depends on multicast groups.
In addition, the TCP corrections finally fixed some long standing
problems that I have been observing that have been very rare, but very
annoying to me. BQTCP is now behaving very well on the network, and I do
not actually have any known issues (at this time) that that are nagging
me. I hope this release will see a further reduction on work on
protocols like IP, TCP and UDP, and future work will be even more
focused on higher level protocols.
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
I hope people find this update useful.
Johnny
