I have a current problem with a samba server. When files are created a shared disk, the permissions on the file are rw-r-----. This is fine for the owner of the file, but the file is shared and needs to be writable by other users in the same group as the owner I have looked on the web and have come across the following arguments that can be used in the smb.conf file. create mask create mode force create mode and similar ones for directories. Does anyone have any experience setting octal permission bits for these arguments, If so can anyone suggest the bits so that I can have files created with permissions rw-rw-rw-, and directories readable and writable by users in the same group, rwxrwxr-x. Any suggestions or advice will be greatly appreciated Peter
Sorry, just a mistake :)

I have been using the following under the share definition.... all works great! create mask = 0777 force create mode = 0777 dos filetimes = yes force directory mode = 0777 t o n y

Seems to have done it, thanks

Let me show you how to catch a fish. The "r w x" in binary will have the values "4 2 1". So, "r w -" will have the values "4 2 -", that sums up to 6. So again, "r w x" will be "4 2 1" = 4+2+1 = 7, hence the create mode 777 E-Mail disclaimer: http://www.sunspace.co.za/emaildisclaimer.htm

For those interested in more detail: man chmod explains, e.g., the optional 4th digit which can be used with access rights, and how the umask affects the rights. -- ----- stephan@s11n.net http://s11n.net "...pleasure is a grace and is not obedient to the commands of the will." -- Alan W. Watts

Let me show you how to correctly catch a fish.
The "r w x" in binary will have the values "4 2 1". So, "r w -" will have the values "4 2 -", that sums up to 6.
So again, "r w x" will be "4 2 1" = 4+2+1 = 7, hence the create mode 777

To be perfectly correct, 4+2+1 is *exactly* the same as 4|2|1: 4 = binary 100 2 = binary 010 1 = binary 001 binary 100 + 010 + 001 == binary 111 binary 100 | 010 | 001 == binary 111 The only time there's a difference between + and | is when the bit patterns of the numbers overlap. e.g., 3+1 ist not the same as 3|1: binary 011 + 001 == 100 binary 011 | 001 == 011 -- ----- stephan@s11n.net http://s11n.net "...pleasure is a grace and is not obedient to the commands of the will." -- Alan W.

4 = binary 100 2 = binary 010 1 = binary 001
binary 100 + 010 + 001 == binary 111 binary 100 | 010 | 001 == binary 111
The only time there's a difference between + and | is when the bit patterns of the numbers overlap. e.g., 3+1 ist not the same as 3|1:
binary 011 + 001 == 100 binary 011 | 001 == 011

Yes but only that speicific case.

It becomes important as you write code: S_IRUSR | S_IWUSR | S_IXUSR S_IRUSR + S_IWUSR + S_IXUSR as you cannot rely on S_I[RWX]USR being single-bit values. Jan Engelhardt --

Doesn't really seem relevant to the case at hand. By the way, addition and bitwise or are synonymous whenever a&b == 0, it has nothing to do with being single bit

i would have thought more important would be 1. how to not use 777 but maybe 755 or even less 2. distinguishing directory and file create masks (not every file must be executable) cheers

Ye, thats more correct, but lets add or-ing to the next lesson E-Mail disclaimer: http://www.sunspace.co.za/emaildisclaimer.htm
