NEWB NEEDS HELP: rsync and ssh and PERL
|
|
| RocketMan 2007-10-12, 7:24 pm |
| Sorry, I am very new and I can't find any examples of what I want to
do.
I am trying to write a command in a PERL script that will take either
the file or the directory I give it and send it to another server via
ssh. I believe that the ssh part of this command would prompt the
user for name/password if there isn't a key already on the other
server which is what I want to happen.
Here is what I have so far (in PERL)
system("rsync -nre --rsh=\"ssh $destHost \" $localFile $remoteDir");
which should end up as:
rsync -nre --rsh="ssh Host" file remoteDir
Since they haven't set me up yet to test this, I wanted to make sure
that:
1) this will work with both files and directories in the 'file'
position.
2) this will check for a key and if there is not one, prompt for user
name and password.
3) this will actually WORK!?
I read the man page and am confused since I see a -l switch for ssh
and I may or may not know the username in this script.
Please let me know what you think
THANKS

If you don't specify the username, and it isn't given in ~/.ssh/config, ssh
assumes that the remote username is the same as the local one.

so lets say that the username does not exist on the remote
machine...will they be prompted for username / password?

But rsync won't use the ssh because the destination is a simple directory
spec. It should be
system("rsync -nre --rsh=ssh $localFile $destHost:$remoteDir");
please read the rsync manual again.
