UNIX for Dummies Questions & Answers

I have 3 servers A, B, C and server B is having some files in /u01/soa/ directory, these files i want to copy to server C, and i want to run the script from server A.

Script(Server A) --> Files at Server B (Source server) --> Copy the files to Server C(Target Server).

We dont have RSA key encypted for SSH, can we do it without using RSA key. if not then please share the process to genrate the key and also the requested script.

Thanks in advance !

What OS ?
Are r-commands available ( remsh, rsh, rcp, rlogin etc...) if so you would need a .rhosts file in the users home directory else you are left with generating keys...
There have quite a few threads on the subject lately, do a little search

I am not sure about these commands.

Here is an (untested) example of how to do it. Suppose I am on 10.0.0.1, and want to copy files from the /home/fpm/from directory on 10.0.0.2 to the /home/from/to directory on 10.0.0.3, I could issue the following command:

Code:

$ scp -r fpm@10.0.0.2:/home/fpm/from fpm@10.0.0.3:/home/fpm/to

The syntax is:

Code:

scp [[user@]from-host:]source-file [[user@]to-host:][destination-file]

To avoid the files being sent twice over the network (from source to local, from local to target), I think it'd be better to login to either node and do the copy action from there.
