- Terminal servers, info-servers and LAVc satellites load their software by
- simply broadcasting a 'LOAD ME' request to the network. DECnet then sends the
- appropriate secondary/tertiary loader, operating system or whatever. To get the
- above message you NCP entry for ANESTH must contain more than just the node
- number (i.e. name a tertiary loader) but the actual file to be loaded does not
- exist.
-
- The failure messages will not cause any problem. The device will just keep
- asking the network until something succeeds in loading it.
-
- DO NOT CREATE an empty file as this will almost certainly screw things up!
-
- AS far as I am aware, the only 'fix' is to install the appropriate server
- software on all routing nodes. Then you'll just get the odd ...
-
- DECnet event 0.7, aborted service request
- From node 10.22 (DUMPY), 24-AUG-1992 11:13:27.40
- Circuit SVA-0, Line open error, Line communication error
- %SYSTEM-F-TIMEOUT, device timeout
-
- ... as someone else beats this node to it! So you can't win. :-)
-
- If you've got bridges in your network, you can play with the filtering to
- isolate where the load requests go, but I've found it's not worth the effort. I
- just ignore them along with the 'adjacency down/up' messages from PCs.
