Message-ID: <703@nih-csl.nih.gov> Date: 4 Dec 90 00:42:56 GMT References: <4890@husc6.harvard.edu> Sender: news@nih-csl.nih.gov Organization: National Institutes of Health Lines: 36 Thanks to Brad & Conrad for their ideas - I guess I should have been more specific... I've installed the Comm toolbox, if that makes any difference. My Mac is on the Ether directly, via a Cabletron card. We do have a FastPath (my apologies, Brad!) doing KIP routing and dynamic IP number assignment for the LocalTalk folks, but I've got a static IP address - should be the simple set-up here. I tried varying the max segment size a bit, but got the same hangup. I tried re-installing the Cabletron driver software, but with no success. I mention the card because one of my colleagues down the hall *DOESN'T* get the hang up - he's got a Nuvotech card, but he's also on a IIfx with lots of other differences. Oh, and the LocalTalk folks don't hang up, either - but it's as reliable as sunrise on this box. It doesn't seem to be time-dependent - I can make it hang almost immediately. I have had a problem with a MacTCP/VMS Telnet not getting along before. My supplier, Process Software, sent me a simple patch, with a warning that "whoever" wrote that client software wasn't doing "proper PSH notification" (?). Once again, NCSA Telnet for the PC and the Mac version with the embedded driver seemed to have no problems (cursor keys wouldn't work), so I kinda suspected MacTCP. *BIG DISCLAIMER* - I have absolutely no idea just WHAT is going on! I know vendors love to point at the other guy and say "It's HIS fault", so I mention this just for reference. I'm posting this message using MacTCP. I really love it. Honest! (-: Anyway, the problem seems limited to this machine. At least my users aren't breathing down my neck for answers! I don't know if there's a general interest here. If you'll reply by E-mail, I'll summarize and post as soon as I figure this *&^%# thing out. Ken Weeks National Institutes of Health, Bethesda, MD.
