WiseDraco · 02-09-2013, 02:08 PM

Hello!
Today i try to copy a whole filesystem from old server to directory of new with command like scp -r -s -v 192.168.1.1:/ /second/Old_server
but it stops after another time with last lines like copy TtyS ?
i try to copy another ( data_ disk ) with that manner and too have a stop. i think, it try copy directory like a /lost+found and stuck there. it be can copy whole system on scp? if i remember xorrectly, cp -ax have do it, it has some similar for scp? search over google, not see a solution...

The problem is that scp won't handle special files like devices. But something like this will do the trick:

ssh root@192.168.1.1 "(cd / ; tar cf - . )" | (mkdir -p /second/Old_server ; cd /second/Old_server ; tar xvf -)

thanks,ill try it tommorow

P.S. and thanks for the slackware - i use it from 4.0, mainly for routers \ servers, but also a 3-4 years also as only desktop system too

some time i use mandriva / mandrake for desktop, but it's "microsoft way" with glucks, and strange things bored me

A quick addendum -- you might have to set umask 000 on the receiving end to avoid filtering perms on /tmp and certain files that might be writable by a group. Here's a fixed command line:

ssh root@192.168.1.1 "(cd / ; tar cf - . )" | (mkdir -p /second/Old_server ; cd /second/Old_server ; umask 000 ; tar xvf -)

Absolutely. Be my guest.

I'm not sure if this is exactly what you need, but you might want to have a look at this:

http://sourceforge.net/projects/g4l/

I'm using it in conjunction with a local FTP server. Works great.
