Use and install ctty, a CLI/TUI connection manager for SSH, serial consoles, telnet lab gear, SFTP, FTP, WebDAV, and S3 object storage. Use when installing ctty; listing/searching SSH hosts or running remote commands; transferring files via a Host alias; looking up saved serial, telnet, FTP, WebDAV, or S3 sites; importing hosts from Tabby; or when the user mentions ctty, SSH aliases, #tags, serial/console, telnet, SFTP, FTP, WebDAV, S3, object storage, port forwarding, or ~/.ssh/config.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Use ctty (CLI, not TUI)

ctty manages **SSH, serial, telnet, SFTP, FTP, WebDAV, and S3** in one tool. SSH aliases live
in `~/.ssh/config` (and `Include` files). Serial, telnet, FTP, WebDAV, and S3 sites live under
the ctty config dir. Agents must drive it **non-interactively**.

| Kind | Agent can | Hand to the human |
|------|-----------|-------------------|
| SSH | `search`, `info`, `ping`, `peek`, `add`/`edit` (flags), `exec`, `ctty <alias> -- <cmd>` | `ctty <alias>` shell, port-forward TUI (`f`) |
| SFTP | `ctty put` / `ctty get` / `ctty scp` + `ctty sftp ls/mkdir/rm/rmdir/rename --format json` | `ctty sftp <alias>` TUI |
| Telnet | `ctty telnet list\|search\|info --format json` | Interactive session (`Ctrl+]`) |
| Serial | `ctty serial list/search/info --format json` | Device manager TUI |
| FTP | `ctty ftp list/search/info --format json`, `ctty ftp ls/get/put/mkdir/rm/rmdir/rename` | Site manager / dual-pane TUI |
| WebDAV | `ctty webdav list/search/info --format json`, `ctty webdav ls/get/put/mkdir/rm/rmdir/rename` | Site manager / dual-pane TUI |
| S3 | `ctty s3 list/search/info --format json`, `ctty s3 ls/get/put/mkdir/rm/rename` | Site manager / dual-pane TUI |

How to install

The exact contents, by fingerprint
mdr add zsuroy/ctty/ctty@sha256:6fe948f1c39121c3

The line at the top of this page pins the label git:20260928.2f02d73, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
