Is there any UNIX or KSH Command to login to an linux/unix server and execute a command and then come back to the original server where u have executed the command.
For Example:
-------------------------------------------------------
SServer1 - Source Server.
DServer2 - Destination Server.
SServer1:/home/->
Login into DServer2 using an UNIX or KSH Command and then execute a command like "uname -a" and exit to the Source Server.
use ssh and setup a cert so pasword is not required.
Then you can eiasly automate this in a script.
SSH/SCP Cert Create
1. Suppose the domain name of your server is server, and your login name loginname.
2. On the client, generate a public and private key.
ssh-keygen -C loginname@server -t dsa
When asked for a password, simply press return.
The private key is stored in ~/.ssh/id_dsa, and the public key in ~/.ssh/id_dsa.pub.
Never give the private key away!
3. Copy the public file to the server with
scp ~/.ssh/id_dsa.pub loginname@server:~/
4. Login on the server with
ssh loginname@server
append the copied file to ~/.ssh/authorized_keys with
cat ~/id_dsa.pub >>~/.ssh/authorized_keys
5. If you want to enable this features on other servers, just repeat step 3 on each of the servers.
That�s it! If you have done everything correctly, the next time you login via SSH or use CVS over SSH, you will not need to enter a password yet you have a secure connection.
