3957.0. "Can't connect from DNS server to hidden area node" by MDRA1::ADIAZ (ALFONSO DIAZ @SQO) Wed May 07 1997 06:12

	Hello,

	I'm having problems connecting from some DECnet/OSI nodes, running as 
	a DNS servers, to any hidden area node. The configuration of these 
	servers is:	
			VAX VMX 6.2
			DECnet/OSI 6.3-6
	

	I can't make any kind of connection, such as a set host, a remote dir,
	a remote copy, etc... The naming cache is working fine, and the 
	backtranslation and nodesynonym links and the object corresponding to 
	the node DEC:.DNA_HIDDEN.xHyyyy are being accesed correctly, as I 
	have been able to check it through a cdi_trace and a cdi_cache_dump, 
	but, at last, the connection fails. For instance, when trying to 
	connect via a set host to a hidden area node, I get the message:
	
		%SYSTEM-F-LINKEXIT, network partner exited

	both if I try it using the node name and if I use the node address of 
	the hidden area node.

	Since I have another system with the same configuration, except that
	this one is not a DNS server, and it is able to connect to hidden area
	nodes, I suppose it must be something related to the fact of being 
	DNS servers.

	Thanks,
	Alfonso.

	What happens if you disable the DNS server, then try SET HOST? Also, try doing the SET HOST with just a network address, not a node name. John Saunders DECdns Engineering

	I believe this is a feature, not a bug. DNS does not support hidden area nodes. The hidden areas incoming connections are filtered on the DNS servers because the hidden area addresses are not unique.
3957.3	Hidden area filter	MDRA1::ADIAZ	ALFONSO DIAZ @SQO	`Tue May 13 1997 04:31`	21
	Hello, There is no bug, this is a feature that can be configured with DECnet/OSI 6.3 ECO5 and 6.3 ECO6, and let you to filter hidden areas. These steps are to be followed to filter hidden areas: (a) Modify SYS$MANAGER:NET$LOGICALS.COM to change from: $! DEFINE/SYSTEM/NOLOG NET$ROUTING_FILTER 1 to $DEFINE/SYSTEM/NOLOG NET$ROUTING_FILTER 1 (b) Modify SYS$STARTUP:NET$STARTUP.COM to change from: $net$ishfilter ENABLE to $net$ishfilter HIDDEN $net$ishfilter STATUS Thank you, Alfonso.
