UNIX for Beginners Questions & Answers

By default, the file will be created with the Primary Group of the user creating the file, so field 4 in /etc/passwd although this can be changed with the newgrp but there are things to consider in the manual page for that too.

You can try to set a file to be a certain grep with the chgrp command.

I would also point out that it would be sensible to ensure that the ID number of the groups should match between the servers. The files are marked as owned by a user number and group number. These number are translated for humans when you use ls -l and similar commands.

If you copy files from one server to another keeping the permissions then the displayed names may change if the user account numbers and group numbers are not consistent.

How it is not working.

The file will be created by mfpts user and will be accessed and modified by another program. Since the other program which modify the file is not having access to this file because it is not created with the csp group. The program is not getting executed and no error in log file it is a zero byte file

This is exactly what i suspected in my post #5 above. You need to make sure that the file is created with the correct group membership. There are several ways to achieve this, but the perhaps most safe one is to set the sticky bit for the group membership of the directory in which the file is going to land. You have shown us a direcctory listing of the file but not one for the directory in which it resides. If the files full path name is /path/to/file issue:

Code:

ls -ld /path/to

to find out about that. This directory should have a group membership of "csp" AND it should have a file mode of "2775" (or rwxrws-r-- in the ls-output, what counts is the "s" in the middle). This will make all created files in this directory to be owned by the same group as the directory owners group, hence, "csp".

I hope this helps.

On each server, could you show us the output from:-

Code:

uname -a
id mfpts
egrep "^mfpts:|^csp:|^csu:" /etc/group
ls -lin                                              # From within the correct directory

This may help us understand. Please wrap each block of output in CODE tags for clarity so it's easy to see which is a working server and which is a failing server.



Thanks, in advance,

As a matter of fact, none of the files shown has any contents. Are we looking in the right direction?

May be below should shed some lights
Can you please let me know why this is happening . If you see below the file I created with one login is having the user as the same id I logged. The other one it getting different user id than I logged in

Code:

(Lnx01:frn:/frn/log>)  touch test
(Lnx01:frn:/frn/log>) ll test
-rw-rw-r-- 1 frn ffr 0 Jan 17 10:31 test


(Lnx01:sfd:/sfd/log>) touch test
(Lnx01:sfd:/sfd/log>) ll test
-rw-rw-r-- 1 pproc ffs 0 Jan 17 10:35 test

This looks like duplicate user id numbers.

Can you show us the output from the following for each server?:-

Code:

egrep "^frn:|^sfd:|^pprn:" /etc/passwd

Thanks,
Robin
