ChadDavis wrote: Hello. I need to know how the group ownership of a file is decided in debian. Also, is it the same for all linux systems? All Linux (and probably Unix) filesystems store a group ID number (gid) on a per-file basis. The gid is looked up in /etc/group to get the textual group name you're used to seeing. All users have a primary group membership as well as any number of secondary group memberships. (use the /usr/bin/id command to get that info) When a user creates a file, that file's group owner is set to the users primary group. You can change the group ownership of a file with the /usr/bin/chown or /usr/bin/chgrp commands. You can change the group membership of a user with the /usr/sbin/usermod command.

However, XSP2 (ASP.NET 2.0) still has a ways to go. Some of my users have asked me to install this module to support ASP.NET on my webserver. Be careful with letting a large number of users run ASP.NET applications as I've heard reports of mod_mono/XSP slowly eating more and more memory without freeing it.

FTP would probably be the fastest, but scp (file transfer over SSH) is probably already on both machines if they're both Linux. PuTTY is an excellent SSH/SCP client for Windows (and Unix) if you need cross platform support. You probably don't want to use SSH Compression as I've seen it actually slow down file transfers over fast LAN links. The SSH encryption might slow down the transfer as well, so the transfer speed might depend on the speed of your CPUs. File size limit is 2GB with smbmount; NFS will take about 14 hours(!) because copying fails after about 1--2 GB with an I/O error unless using sync mode. This sucks ... True.
