Greetings all: I currently have three Windows NT 4 domains. I'm evaluating the switch to either (at least) a mix of RedHat Linux or a total switch to RedHat. For file serving processes, I'll utilize SAMBA. For my first test, I've been looking at/trying to duplicate and then replace the services of my least obtrusive server - our Proxy Server - with an older workstation for the Linux machine. One of the core functions of this server (outside of Internet Access) is handling our FTP site. Currently I have the folders (directories) that house our FTP site open to the Internal LAN so my users can deposit files on to them without asking (bugging ;-) ) me. So, of course I want to do this with Linux/Samba. I've got the machine running - using winbind to authenticate users at the domain controllers and not locally. But I'm having a sporadic problems with the Linux machine "disappearing" from network. Let me try to be more specific: Linux Machine info: Gateway 2000 GP6-350 (Pentium II 350) with 256MB of RAM 2 Network Cards - 3Com 905CTX (eth0 "External"), Netgear FA311 (eth1 "Internal") RedHat Linux 7.3 (all latest patches from Red Hat Network yesterday) SAMBA 2.2.6 (from samba.org yesterday) Built SAMBA with the "--with-winbind" switch
