Yes. FTP should be entirely suffiecent. Since tar is also said to be available on the old box, the OP actually has all he needs. These two alone should be all the OP needs. He will need to install a ftp server on the new CentOS box: 'yum install vsftpd' will do that. Then he needs to do some configuration of vsftpd to allow incoming non-anonymous ftp with write ability. He will then be 'golden'. > -- Robert Heller -- Get the Deepwoods Software FireFox Toolbar!

With ssh I can do this from boxA: ssh someone(a)boxB | tee saveit After I get connected to boxB, in the remote shell, I could do: cat somefile exit Then back on boxA I will have a file, saveit, containing somefile. saveit may need to be edited to remove the motd and PS1 that the remote shell would add. I wouldn't do this myself, as I know how to use scp, but I have done it, just to see it work. I assume, (maybe a bad thing) that from the new box the OP could do: telnet remotebox | tee saveit And in the telnet sessiion on the remote box execute: tar --create --file - path exit Then fix the file saveit on the new box. This may be a brutish way to do it, but I am a construction worker, and it still is softer than a hammer.

It does, but running md5sum on 10000 files manually is way worse than having it done automatically by rsync.

Yee gads. Imagine doing this for 10000 files with most being binary files, with potential file corruption problems. It is like using a nailfile to tear down an office block. > |
