I'm having trouble with an NFS/SAMBA server.

Our server 192.168.21.80 is running both SAMBA (for windows clients) and NFS (for irix clients).

When I log in as root on the irix machine I can write to the file server and anybody can modify it which is what I want.

The problem is that the program running uses "flame8_5_6" as the username. When I create a file under this user nobody else can modify it.

Here are the permissions when I run an ls -la

drwxr-xr-x 2 65534 65534 48 Oct 10 07:48 test (When logged in as root)
drwxr-xr-x 2 flame8_5 user 48 Oct 10 08:17 test2 (When logged in as flame8_5_6)

Any ideas how I can fix this?

Here's my /etc/exports


/disc1 *(rw,all_squash,sync)
/disc2 *(rw,all_squash,sync)
/disc3 *(rw,all_squash,sync)
/disc4 192.168.21.94(rw) 192.168.21.93(rw)
/disc5 *(rw,all_squash,sync)
/disc6 *(rw,all_squash,sync)
/disc7 *(rw,all_squash,sync)
/disc8 *(rw,all_squash,sync)

well this is nothing to do with (your amazingly insecure and vulnerable) NFS implementation, just the umask of this particular user. if you run "umask 000" as your user then any files you create are going to be world writeable. again this is massively insecure and i'd urge you to think of a more intelligent solution here...

Yea I realised it's very unsecure. Unfortunately every single person in the company needs RW access to all files on all those folders.

Thanks for the help. It's working!!!!!
