hi viket, did i ever mentioned in my mail that permission 1775 will set the _gid_ bit. i just said it will set the stick bit which is same as in the case of /tmp directory.
to set the gid bit u'll have to give 2775 and not 1775. in normal scenario if a file does not have write permission but the parent directory has, then still you can forcefully modify/delete the file, which is prevented by the sticky bit. i hope its clear now... ----------- Muzaffar Ansari +91 9224339939 [EMAIL PROTECTED] ----- Original Message ---- From: Viket Trivedi <[EMAIL PROTECTED]> To: [email protected] Sent: Friday, August 29, 2008 1:48:38 PM Subject: Re: [LinuxVadaPav] Need to set directory permissions Hi, can you please check the significance of a GID bit. When a GID is set on a directory, any file or directory created under that will have the group ownership for that file or directory. The concept was introduced for the same purpose that many users of the same group using a single source can access each others files and use it. regards, Viket On Fri, Aug 29, 2008 at 1:16 PM, Muzaffar Ansari <ansarimuzaffar@ yahoo.com>wrote: > hi viket, > > i have mentioned clearly that "given their umask is set to 022" which means > any files n directories created by the user of group portal under share > directory will have their file permission set to 644 and directory > permission set to 755 which clearly means the files n directories dont have > group permission so how come users will b able play around with others file. > > > > ----------- > Muzaffar Ansari > +91 9224339939 > ansarimuzaffar@ yahoo.com <ansarimuzaffar% 40yahoo.com> > > ----- Original Message ---- > From: Viket Trivedi <viket.trivedi@ gmail.com <viket.trivedi% 40gmail.com> > > To: linuxvadapav@ yahoogroups. com <linuxvadapav% 40yahoogroups. com> > Sent: Friday, August 29, 2008 9:39:18 AM > Subject: Re: [LinuxVadaPav] Need to set directory permissions > > Hi, > > If you create a group as you mentioned portal and add all the users in that > group and further set GID bit on the directory, > any files created in that directory will have a default group permissions. > which will allow any user of that group to easily play around with files or > subdirectories. > > Hope that clears the confusion. > Best is read document on what GID does and try out the solution. which will > enable you the problems. > would be glad to help you further if you try the solution and mention what > problems you face further. > > regards, > viket > > On Thu, Aug 28, 2008 at 5:57 PM, Muzaffar Ansari > <ansarimuzaffar@ yahoo.com>wrote: > > > hi viket, > > methinks all users created will have a common group say portal... > > thus change the group ownership to portal and give 1775 permission to the > > directory say share, > > # chgrp portal share/ > > # chmod 1775 share/ > > the permission will be something like below, > > drwxrwxr-t 2 root portal ... share > > in this case users with group portal will be able to create files and > > directories under the directory share with their ownership and with the > > sticky bit on the parent directory, no users will be allowed to play > around > > with other users files and directories (given their umask is set to 022). > > > > > > ----------- > > Muzaffar Ansari > > +91 9224339939 > > ansarimuzaffar@ yahoo.com <ansarimuzaffar% 40yahoo.com> > > > > ----- Original Message ---- > > From: Viket Trivedi <viket.trivedi@ gmail.com <viket.trivedi% > 40gmail.com> > > > To: linuxvadapav@ yahoogroups. com <linuxvadapav% 40yahoogroups. com> > > Sent: Thursday, August 28, 2008 3:23:00 PM > > Subject: Re: [LinuxVadaPav] Need to set directory permissions > > > > HI, > > > > Try setting GID bit on the folder where you need to give access to users. > > > > Regards, > > Viket > > > > On Thu, Aug 28, 2008 at 10:38 AM, ShrikantPatil <shrikant_neo@ yahoo.com > > >wrote: > > > > > Hello friends , > > > I have a portal in which all users need to upload files , but I am not > > > able to give permissions to them to specific folder as , they all are > > > created at runtime with the username. > > > > > > Is there any other way , by which I can already set permission to > > > "public" folder which will automatically applies to new folder under it > ? > > > > > > I can't set umask to 0000 . > > > > > > Thanks and regards, > > > Shrikant > > > > > > [Non-text portions of this message have been removed] > > > > > > > > > > > > > [Non-text portions of this message have been removed] > > > > [Non-text portions of this message have been removed] > > > > > > > > [Non-text portions of this message have been removed] > > [Non-text portions of this message have been removed] > > > [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
