[HECnet] Multinet circuit costs

Why? What is the percieved problem?

  I don't know about area 44, but I was talking to Hans on New Years Eve
about a problem where he could not copy files, while logged in to OZON, from
LEGATO (i.e. a "pull" transaction).   According to Hans, it fails with "acp
file or directory lookup failed".   If I did the same thing from my end (a
"push") it would start copying and actually create an empty file on OZON,
but then time out after a very long time with 

	-RMS-F-SYS, QIO system service request failed
	-SYSTEM-F-LINKABORT, network partner aborted logical link

Last I heard Hans was going to check the NETSERVER/FAL logs on his side for
any error messages, but that was New Years Eve and he was otherwise occupied
:-)

  I see this morning that Hans has actually created a file "TARGET.TXT" on
LEGATO (dated 6PM PST on 12/31 even - what time is that in the
Netherlands??) so maybe he's solved the problem.   If he did he didn't tell
me what he did.

  Hans also mentioned to me that he was having similar problems with the
node STAR69 and CANADA.   I think all this came up when Hans was trying to
write his HECnet crawler script to gather INFO.TXT files...

  I don't think this is related to the Multinet/Bridge configuration, but I
can't guarantee it.   One hidden "gotcha" in DECnet is that the circuit costs
are determined locally, so the routings don't have to be symmetrical (i.e.
the route from A->B might not be the same as the route from B->A).

  If somebody (Johnny??) wants to try to figure it out, be my guest -
GUEST/GUEST.   I'm a little busy at the moment and don't really have time to
look at it.

Bob
