Well, I managed to get the bridge compiled up on Solaris with some minor makefile and include and library tweaks having compiled up the latest libpcap. I am using the opencsw archive for general unix software. If I run the bridge with debug on I get the following output: ./bridge 4711 Config filename: bridge.conf Adding router ''local''. 0001187c:-4206648 Adding router ''update''. 82ee1319:4711 Adding DECnet bridge local. Trying to match local Matching against: local Found match: local == local Adding DECnet bridge update. Trying to match update Matching against: local Matching against: update Found match: update == update Adding LAT bridge local.

Port is 1 Which looks encouraging, but when I try and use DECNET on SLAVE I get the following: [MSW]SLAVE$ dir mim:: %DIRECT-E-OPENIN, error opening MIM::*.*;* as input -RMS-F-SYS, QIO system service request failed -SYSTEM-F-PATHLOST, path to network partner node lost Any ideas what might be going wrong? I've updated my NAT to point to the Ultra 5 for port 4711. Regards, Mark.
