Do you know what is the equivalent file for TOPS-10? Is that SYSJOB.INI? opr.ato Understood. Now I've got another problem. The TOPS-10 node goes yo-yo: $ %%%%%%%%%%% OPCOM 9-JUN-2012 13:58:58.19 %%%%%%%%%%% Message from user DECNET on BITXOV DECnet event 4.18, adjacency down =46rom node 7.60 (BITXOV), 9-JUN-2012 13:58:58.19 Circuit QNA-0, Adjacent node listener receive timeout Adjacent node =3D 7.80 (BITXT1) $ %%%%%%%%%%% OPCOM 9-JUN-2012 13:59:09.10 %%%%%%%%%%% Message from user DECNET on BITXOV DECnet event 4.15, adjacency up =46rom node 7.60 (BITXOV), 9-JUN-2012 13:59:05.04 Circuit QNA-0, Adjacent node =3D 7.80 (BITXT1) =20 The TOPS-20 one is connected to the same virtual bridge and it is = running in the same virtual machine, but it runs OK. Any idea? (My = suspect is the NI configuration in the KHL ini file...) It's outside tops10, I guess, and I'm completely lost there. If my braincells starts to work I will rember how to log all the DECnet packets on the -10 side. --P
