RE: IFS object authority

[Patrick.F.O'Dowd@xxxxxxx]

Apologies if this is off topic!
On hp-ux i set the umask in the .profile to 000, i though this would give
rwxrwxrwx to anything created under the profile. When I create shell
scripts they have rw-rw-rw- i.e. no execute permissions. Any ideas why and
how can I give execute permissions without having to do a chmod manually?
Thanks

Thanks, Roger....  That article does a great job describing the behavior.

What's missing from the IFS implementation is the concept of the umask...
Basically, it describes the default creation
permissions based on user choice.  In linux (and unix as well....) a
created object's permissions are based on the user
(that is the creator) the user's primary group (usually the same as the
creator), with read authority granted to the
world (*PUBLIC). Unlike the instructions in the Knowledge base article,
there is no need to modify any permissions to
allow group access (at least read only).  Of course, one can set the
"sticky bit" to inherit the permissions from the
parent. This is all controlled through the umask and can be user
configurable.

Our issue with the IFS is that if one uses FTP to create files, one must
resort to command line to get the permissions
right; it occurs using shared drives as well.  It's an added step we don't
see in either Linux or AIX.

Not sure if we'll ever see the IFS handle this... My guess is the IBM would
rather have a machine running both Linux and
OS/400 and get the best of both worlds.  It's an option I'd love to
explore....

thanks for the info!!!

Dan,

Check out the Knowledge Base article 18314911 at:

http://www-912.ibm.com/s_dir/SLKBase.nsf/0/e3dc97d7f1aeaf348625685f005c6263?OpenDocument&ExpandSection=1&Highlight=0,ifs


It helps explain the IFS security and how it is based on Unix. Notice
that how Owner is handled on new objects is different as of V5R2.
