Sorry, but it's not possible to do this with conventional Linux permissions or NFS. The permissions of a newly created file depend only on the hard-coded MODE (666 for files, 777 for directories) and the user's umask. So, either the users have to remember to set their umask, or use a different account with a correct umask to access that dir (you could try two accounts for each user with the same uid - it might work but I haven't tried it out myself), or have the user chmod each new file they make. Thsi question came up on another list recently, and some workarounds I thought up were variations on using cron, find and chmod. Maybe there's some way you can hook fam and call a script each time a file is newly created. But the easiest way is to simply export the filesystem in a way that does do what you want - samba. As long as the total number of connectiosn through samba for Linux and windows clients stays below some sane amount (I find 5-10 is usually about the maximum) the file server will cope ok. alan -- gentoo-user@gentoo.org mailing list
