Well, maybe there are some unixes that don't change uid/gid, but I'm not sure what the rules about preserving such data would be. How do you keep from conflicting with the same uid/gid on the target system? If there's a UID=500 for me on machine a, what's to say someone else doesn't have that same UID elsewhere? I find this suspect. So, I tried an expiriment. Look at the following: #ls -l janina+paula.jpg -rw-r--r-- 1 pet pet 31191 Dec 30 2000 janina+paula.jpg [root at concerto 19:53:59] pet#scp janina+paula.jpg janina at bumpy: janina+paula.jpg 100% 30KB 1.1MB/s 00:00 [root at concerto 19:54:50] pet#ssh janina at bumpy Looks like the ownership got changed. janina at bumpy:~$ janina at bumpy:~$ ls -l janina+paula.jpg -rw-r--r-- 1 janina users 31191 Sep 29 19:55 janina+paula.jpg Jack Mendez writes: > okay but we were talking about preserving the permissions of the data, user > accounts do not need to be on the system the files are going on too in > order for the right permissions to be on them, in fact, if its just about > storing the files elsewhere gid and all of that gets retained even of those > id do not exist on the system > At 07:26 PM 9/29/2004, you wrote: > >But he's not giving them accounts on the target system.
