Does the system support ssh, NFS, ftp or rsh. If you have ssh or rsh then you could use rsync, if it supports NFS then you can export a directory from either the old machine or the new one and then mount it on the other system and them just do a cp. FTP or rsh would require you to install a server on the other system, there will be several choices for an FTP server on whatever distro you are using on the new system. RSH will be available as an option on the new system also. RSH is part of the legacy server group, it's not normally installed on modern systems because ssh replaced it but it will be available. If you have either ssh or rsh then you don't need a tar file, just use rsync (which can use either ssh or rsh as it's underlying transport). rsync -r -t -l -p src_path dest_machine:/dest_path

A CentOS 5.5 system will have sshd running. Assuming the firewall is properly configured (to allow ssh, port 22) though, at least on your local LAN (assuming both machines are on the LAN). You should be able to do this (assuming also that the Caldera box has open ssh installed -- I would expect it does): on the Caldera box: tar cvf - files-or-directories | ssh user(a)centosbox tar xvf - > > Many thanks, > -T > -- Robert Heller -- Get the Deepwoods Software FireFox Toolbar!

In any event the OP said that the Caldera box doesn't have ssh on it. The more I think about it the more I prefer the idea of just moving the disk from the old box to the new box and doing the copy there.

In > any event the OP said that the Caldera box doesn't have ssh on it. Yes, I sent my reply before seeing that message. :-( I expect he does not have rsync either. The advantage of tar is that it is on the Caldera box... Apearently the Caldera does have a ftp client as well as tar. Probably the most workable option would be to make one (or more) tarballs and ftp them over (the OP will need to install vsftpd (yum install vsftpd) on the CentOS 5.5 box and enable non-anonymous ftp logins w/ write access). > > The more I think about it the more I prefer the idea of just moving the > disk from the old box to the new box and doing the copy there. Except appearently, the old Caldera box uses some old RAID card that might not be supported with the new box... It might be far more hassle to transplant something like that. I would agree if it was just a single bare drive. > -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/ |
