The situation.

We have a Redhat 7.2 server acting as a file server between a number of windows and Solaris clients with the NT clients using Samba to connect and write data to the shares.

The problem

The account used by the NT machines uses default file permissions of rw-r--r-- which causes problem when a script running on the solaris machine attempts to manipulate the files in question.

The Question

How can I change the default file permissions put in place by the NT account to ensure that other accounts have write access to those files? (all the accounts in use are in the same group so just being able to set the group permissions would I guess solve the problem).

My apologies in advance if this is a simple question I "should" know the answer to

In smb.conf you can set either per-share "create mode"s. This should solve your problem.

Thank you, thats done the job nicely.

you have create mask = 0664
or
create directory = 0775
numbers may change

On the share in question I had neither (samba is still a scary Lion round this neck of the woods, it looks bloody smashing, but one wrong move and I get mauled to death )

I added create mode = 0777 to the parameters of the share and files created by the NT accounts are now being created rw-rw-rw- which is just what I was trying to do.

I will be having a look at those settings as well, currently we have the extremely fun task of being Windows monkeys trying to learn Linux/Samba in a live operational environment which makes tinkering an interesting occupation.

btw
0777 should give you rwxrwxrwx permissions

Thats what I thought, I assumed that as they are not executable files that they were not granted execute permissions or am I just giving Linux too much credit?

My method of working at this stage is to get the solution working first and then worry about getting it working correctly
