MS ? I'm clueless :-) > Also, I don't have "erratic come & go problems", > but the mount(8) command simply hangs right from the start. Good, intermittents are harder to chase. I had a bad solder joint on a coax BNC once, intermittent, pings worked, some protocols broke, & had an electolytic die in a UTP hub power that similarly caused intermittents through low voltage. > I'm not using amd, if that matters (I don't think it does). Agreed. (Just mentioned it in case you were doing anything unusual, eg my hosts mount themselves occasionaly, to allow transparent host independence/ orthogonality of scripts). More a question if other host mounting yours. I recall X terminals can try unusual boot methods inc NFS, maybe other devices eg TCP printer spoolers to parallel converters too etc ? Maybe if you remove all but your 2 hosts on to a seperate net briefly for a test to see if some weird 3rd party problem ? (a bit like ripping spare cards out of a problematic PC). > Since I weren't able to track this problem down, I now tend > to think that it's a bug in the NIC (either broken hardware > or a bug in the bge(4) driver) that makes it break TCP NFS > packets somehow. I don't have any other explanation. I think you've already checked no ipfw in way either end (your old mail not to hand). Sometime my probs come down to eg: bad cmos battery on a cold standby gate I power up, timed masters off the spare gate, zaps internals, rdist of configs fails, named fails, NFS fails. All 'cos I turned a box on :-) Good luck. -- Julian Stacey. BSD Unix C Net Consultancy, Munich/Muenchen http://berklix.com Mail Ascii, not HTML.
