Using ssh command inside a script
Hi,
I have a script file in server A. Inside the script file, I first have a ssh command that will connect to a remote server B. In the same script file itself, I have a sequence of commands that has to be run in server B. I am embedding these commands in the script file that I have in server A. When i run the script file in server A, it first gets connected to server B but nothing happens for sometime after which i get Connection timeout and some error in the command.
Is there a restriction in the kind of commands that can be executed in server B from server A with the scenario as mentioned above?
Instead of a script file, when i execute the commands one by one in console in server B it is getting executed. ie) first i connect to server B from server A using ssh and then run the commands one by one in server B. I want these commands to be placed in a script file and executed from server A.
Kindly provide a solution.
Thanks in advance.
