rcp : preserving file ownership

[Chern Jian Leaw]

HI,

I'm executing rcp as a root user from a src machine hostA to destination machine hostB.

I'm copying a user's file i.e ken_lee whom exist on both hostA and hostB.The file to be copied, file1.cc does not exist on the destination.

hostA
-r-xr-xr-x 1 ken_lee wmt .... file1.cc

I had invoked rcp from hostA as follows:
#rcp -i /dir1/file1.cc hostB:/dir1/

whereby user ken_lee also owns dir1 in hostB.

However, the -p option does not seem to preserve the source ownership.

Upon copying, contents of dir1 in hostB is as follows:

hostA
-r-xr-xr-x 1 root wmt .... file1.cc

The original group is preserved, but not the owner.

I could do a chown to change the ownership manually, or a chown -R if there're many files to be copied without having the ownership preserved.

But does anyone know of method of preserving the ownership during remote copy of rcp?

Thanks.

Hi,


The rcp(1) manpage says (for the -p switch):

--
Preserve (duplicate) modification times and modes (permissions) of source files, ignoring the current setting of the umask file creation mode mask.
--

I'm afraid there is no way to preserve owner/group by using the rcp command only.

It should be possible, though, to change the destination files (on the other server) by using remsh commands.

Bye,
Rik

What is the UID of ken-lee on host B.
Is it 0.
I assume it is zero.
So when you have copied the file using the rcp -p option it has preserved the file owner as 0,copied to host A and there check for the passwd file for uid 0 and took it as root.

rcp with the -p option should preserve the ownership.

Please check it out.

Thanks

TG,
UID of ken_lee in hostB is not 0, but 17219 on both host machines.

Any ideas?

It seams preserving ownership does not work with rcp.

But you can do something like that:

tar cf - source_dir | remsh remote_host "cd remote_dir; tar xvpf -"

And check this thread (same thing with cpio):

Hope this helps,

Hi

Preserving ownership will only work if both machines are the same for group / group number and user / user number.

Files do not carry the ower/group name but the owner number and group number and translate them to user name and group name when required.

Try taring it

# tar cvf - /.../ | remsh dest tar xvf -

I'm pritty sure there is another example in man tar
