[Bug]: SSH Connection Fails When Host Alias Contains Underscore

[duracell]

Current Behavior

When selecting an SSH connection where the Host alias contains an underscore (e.g., test_1): 1. No connection attempt is made (no outgoing TCP packets detected). 2. Clicking “Reconnect” has no effect. 3. Renaming the Host alias to remove the underscore (e.g., test1) resolves the issue. It works fine outside of Wave.

Expected Behavior

1. Connections with underscores in Host aliases should work if supported by SSH.
2. If unsupported, a clear error message should appear (e.g., “Invalid characters in SSH Host alias”).

Steps To Reproduce

1. Create SSH config entry:

Host test_1  # Underscore in Host alias
  HostName example.com
  User test

2. Attempt connection via Wave’s laptop icon.
