User file permissions

tapanga · 07-05-2004, 02:43 PM

I have a samba file server with 3 groups with users belonging to groups as such

groupA:user1,user2,user3
groupB:user1,user2,user3,user4,user5,user6
groupC:user1,user2,user3,user4,user5,user6,user7,user8,user9

I have shares set up
shareA : belongs to groupA : owner user1
shareB : belongs to groupB : owner user4
shareC : belongs to groupC : owner user7

i have some filed in shareB that can be read and executed by the whole group (groupb) but may only be modified by user4 and user5

please help

How are the prmissions set up for the other users? Can they write as well as read?

tapanga; not quite sure ? from what read u may give all or some all permissions to do some things or everything. word of advice depending on
the critical use every one whom has root privileges could cause havoc in system. reading ok writing 1/2,executing only trusted. just do it very carefully.

here are the file permissons of one of the files

owner : user4
group : groupB

owner : read - write - execute
group : read execute
other : none

Well there's your problem. Only the owner can modify the files.

penguin4 · 07-05-2004, 07:13 PM

tapanga; very carefully. do take time to read this expanded.http://tldp.org/
HOWTO/HOWTO-INDEX section4.2 subsections 4.2.1 configuration/Installation, 4.2.6 security.

tapanga · 07-05-2004, 08:24 PM

this sure is going to be alot of reading - did u mean specific links within those subsections????

XavierP · 07-06-2004, 03:22 AM

Tapanga - a better link is here: http://www.linuxquestions.org/questi...ticle&artid=20 - an article on LQ about permissions.

tapanga · 07-06-2004, 11:19 AM

Thanks for the link - I have read the doc - but still don't see how i allow 2 users in group to read write and execute and the other users of the group to only read and execute.

I'm obviously missing something here

I want to restart this thread.Did any one know how to grant different permissions to different users for a same file?(i.e.user1 and user 2 has read,write and execute and user3 has only read and execute.All three are under the group myusers).I am also studying

.Thanks in advance.
