Authorization notice. Termish is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.
Remote script. Termish can offer guided installation of Herdr on the remote host, so review what the installer changes before accepting it.
Credentials. SSH passwords or private keys are stored in the phone's Keystore or Keychain, so protect the device with a lock.
Who it is forA developer away from their desk who needs to give a coding agent a task on a remote development machine and follow its progress.
The problemCoding agents run on a remote computer, but the developer has only a phone and needs a reliable way to start tasks and see results.
The outcomeCodex runs inside Herdr on the remote host, and the developer can see live output, send a screenshot or file, and review the result from the phone.
What you need first
- An Android 8.0+ phone or an iOS device with macOS and Xcode for building
- A reachable development machine or server with SSH access (Mosh also needs UDP and mosh-server)
- Login credentials or a private key for that remote host
- For builds: JDK 17, the Android SDK and Rust via rustup
Steps
- Open Hosts in Termish, tap
+, and enter the SSH address, username and password or private key. - Verify the server's host key fingerprint on first connection.
- Open the host menu and choose Herdr. If Herdr is missing, accept Termish's guided installation.
- Start Codex from Herdr, give it a task, and follow its output in the terminal.
- Upload a screenshot or file if useful, then check the result through the remote-screen window or in the terminal.
Prompt for your agent
Using the farlume/termish README, give step-by-step instructions to connect a phone to <host> over SSH, open Herdr, and start Codex with the task <task>. Expected output: a numbered checklist of app steps. Verify that the checklist includes host key verification before the first login.
Caveat. The README gives no list of Codex or Herdr versions that are tested, so confirm compatibility on your own host.
