Hi Zheng, Additionally, I notice that as long as I don't do anything with that directory, the permissions stay wrong.
Previously I noticed that the permissions eventually got right by themselves, but I don't know what triggered it. Also, the permission problem is not just with the first ever created directory, it happens to files too: [host1 bla]# touch hoi [host1 bla]# ls -al -rw-r--r-- 1 root root 0 20 jun 00:05 hoi [host2 bla]# ls -al -rw-rw-rw- 1 root root 0 20 jun 00:05 hoi Notice the additional group and world writable flags. It works the other way round too: [host2 bla]# touch hoi2 [host2 bla]# ls -al -rw-r--r-- 1 root root 0 20 jun 00:09 hoi2 [host1 bla]# ls -al -rw-rw-rw- 1 root root 0 20 jun 00:09 hoi2 However now after a couple of seconds I re-check on host2, and the permissons have changed there as well: [host2 bla]# ls -al -rw-rw-rw- 1 root root 0 20 jun 00:09 hoi2 So now it's group and world writable on both hosts. Kind regards, Erik.
