Telnet, rlogin and Serial
Telnet, rlogin and Serial connections live on the Connections page with the file connections. Each one opens as a terminal pane, like an SSH session: it splits, broadcasts, runs snippets and is kept in layouts. They have no Files tray and no tunnels.
Telnet and rlogin come with every plan. Serial needs Pro.
Add one
Section titled “Add one”- On the Connections page, press New connection.
- Give it a Name, such as
core-switch. - Under Kind, pick Telnet, Serial or rlogin from the Terminal row.
- Fill in the fields below, and press Save.
Telnet
Section titled “Telnet”“Network gear and old servers.”
| Field | What to put |
|---|---|
| Address | The device’s name or IP address, such as 10.0.0.2. |
| Port | Leave it empty for 23. |
| Raw TCP | Tick it for a console server port that wants plain bytes and no Telnet negotiation. |
Under Advanced:
- Terminal type: what Vaulterm tells the server it is,
xterm-256colorunless you change it. - Backspace sends: DEL (most devices) or Ctrl-H (older devices).
rlogin
Section titled “rlogin”“Old equipment that only speaks rlogin.” Fill in the Address, the Port (513 if empty) and the Username. Advanced has Backspace sends.
rlogin servers often want the connection to come from a privileged port. Vaulterm tries one first, and if this computer doesn’t allow it, the pane says “This server needs a privileged source port, which this computer doesn’t allow Vaulterm to use.”
Telnet and rlogin aren’t encrypted
Section titled “Telnet and rlogin aren’t encrypted”Neither can be encrypted, so the editor says “Telnet can’t be encrypted: what you type, passwords too, is sent as plain text.” The connection’s row and its pane show a Not encrypted chip. Use them only on networks you trust, or for devices that offer nothing else.
Serial
Section titled “Serial”“A console cable on a port of this computer.”
- Pick the Port. The list shows each port with what it is, such as
/dev/ttyUSB0 · FT232R USB UARTorCOM5. Refresh ports looks again after you plug a cable in. For a port that isn’t listed, choose Type a path… and enter the Path. - Under Line, pick 9600 8N1 (most switches and routers), 115200 8N1 (many boards and newer routers) or Custom.
- With Custom, set the Baud rate, Data bits, Parity and Stop bits.
Advanced has:
- Flow control: None, XON/XOFF or RTS/CTS.
- Enter sends: CR, LF or CR LF.
- Backspace sends, as for Telnet.
- Local echo: “For devices that don’t show what you type.”
While it’s open
Section titled “While it’s open”- Send break is in the pane’s menu, for devices that need a break signal (to reach ROMMON, say).
- Pull the USB adapter out and the pane says it’s disconnected, “Looking for it every second.” Plug it back in and the pane reopens it, even on a new path. Try now looks straight away and Stop gives up.
- If the port can’t open, the pane says why in plain words, such as “/dev/ttyUSB0 is in use by another program” or “/dev/ttyUSB0 isn’t there”, with Reconnect.
On Linux, opening a serial port usually needs your user in the group that owns it, often dialout. If it isn’t, Vaulterm says which, for example “No permission for /dev/ttyUSB0. Add yourself to the dialout group, then sign out and in.”
Without Pro
Section titled “Without Pro”Saved Serial connections stay listed, and you can edit and delete them, but Open shows a lock, which offers Pro. A Serial pane that opens without Pro, from a layout say, says “Serial connections come with Vaulterm Pro.”
Open one
Section titled “Open one”Press Open on its row, or find it in the Command Center or in a new tab’s list of where to connect. While it connects, the pane says where, such as “Connecting to 10.0.0.2:23…” or “Connecting to /dev/ttyUSB0 · 9600 8N1…”. When the connection ends, Reconnect opens it again.
