A file's Default Group on creation

I have an NFS/Samba share on my server, the share is on an ext3 filesystem. I want all files inside of this share to be owned by a certain group (media) so that all of the users in that group can access the files. As it is now, if i create a file from my arch desktop (NFS), it is owned by my account and the users group. And then people on the samba share or my other computer running arch can't access the file i created without me having to chown it. The only way I can think of to solve this would be to use a script on crontab (doesn't sound very efficient).

Re: A file's Default Group on creation

Setting the setgid bit on a directory (eg, "chmod g+s /path/to/dir") will cause all files created therein to be owned by the owner of the directory.  New directories created therein will inherit the setgid bit but existing subdirectories will not, so if you have an existing directory structure, use the -R arg to chmod to recursively add the setgid bit.

you could also use incrond. see website and forum search.

Thank you, this seems to be working perfectly.
