Is there a fix for this? I tried upgrading to 1.1.46 and 1.1.50 but they both just hang after a while..so that's no help at all. I may try 1.1.33 later. -- Brian Kramer - Owner/Systems Administrator - bjkramer@pluto.njcc.com New Jersey Computer Connection - Public Access Unix Site - pluto.njcc.com Voice: 609-896-2799 - Fax: 609-896-2994 - Dialups: 609-896-3191 Dialup or Telnet to pluto.njcc.com and log in as guest for more information. ------------------------------ From: engel@yacc.central.de (C.

How can I let everyone mount the diskette type he wants. It's a permission question and I 'm generous but not everyone should have the root-passwd.

Actually, every motherboard I've seen lately that'll go to 50 MHz is a 33/40/50 MHz (sometimes even 20 & 25) with local bus. The VLB slots won't work at 50 MHz, though. Don't cheat yourself.

Both ping and rlogin need to open a socket lower than the 1024 mark.
