Multiple Hop SSH access
I have a desktop computer, homepc, at home and I want to access my desktop computer, workpc, at work. However, workpc does not have an public ip, therefore, it is not directly accessible from home. I have go through the gateway computer, Gateway.mycompany.com, at work.
Note: WorkPC can the internal IP address or internal host name recognized by Gateway. The host name (or ip address) of the Gateway must be public accessible.
Note: if nc is not installed on the Gateway, you can try the following command instead:
ssh -oproxycommand="ssh Gateway.mycompany.com nc %h %p" WorkPC
Note: WorkPC can the internal IP address or internal host name recognized by Gateway. The host name (or ip address) of the Gateway must be public accessible.
