Jump hosts

What jump hosts do

Section titled “What jump hosts do”

A jump host (bastion) is an intermediate SSH server that your connection passes through to reach a target on a private network. SigilTTY supports chaining up to 10 hops.

Setting up a chain

Section titled “Setting up a chain”
  1. In the server profile, add one or more jump hosts in order.
  2. Each hop has its own address, username and authentication method.
  3. Connect as usual — SigilTTY establishes the chain hop by hop.

Security along the chain

Section titled “Security along the chain”

Every hop’s host key is verified independently, exactly like a direct connection: recorded on first use, and blocked if it changes. See Host key verification.

If a target host needs your local key for authentication (for example, to pull from a Git server), see Agent forwarding — every forwarded signature is approved on your device.
