The generalisation to multiple-hop SSH is not trivial and may imply the combination of tunnels and usage of SSH configuration like Prox圜ommand and ProxyJump. This is handy to directly access hosts under a gateway (or even proxy some commands to such hosts).

Specific ports and keys can be incorporated. Firewalls can be configured to ignore these packets, so if you go through a firewall that drops idle connections, these may not keep the connection alive. an HTTPS-based REST API would be accessed via Double SSH hopĪ double-hop in SSH will jump from localhost to a remote server, having an intermediate hop on an intermediate server. Is it possible to keep an SSH tunnel alive longer with this as well Stack Exchange Network Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. To keep the session up, the client can send a keep-alive signal to the server if no data has been received for some time, or symmetrically the server can send messages at regular intervals if it has not heard from the client. Hi, Gregg Green There is a such timeout in Preferences Tools SSH Configurations Connection parameters Send keep-alive messages every.

With the tunnel in place it is possible to access this service from localhost e.g. By default, the SSH session automatically logs out if it has been idle for a certain time.
