SSH Channel

Go To Product Page

SSH Channel turns IO Ninja into a versatile SSH client. Use terminal view and work with your server like any other SSH client, or use IO Ninja’s extensive data handling capabilities provided in log view.

Basic Setup

In IO Ninja, click the “New Session” dropdown and select “SSH Channel”.

Enter the address of the server you want to connect to and press “Connect”.

Enter your credentials and press “OK”.

If required, press the “Show Terminal” button to enter terminal mode.

You may now use SSH Channel as you would any other SSH terminal.

Adjust settings as needed via the “Settings” button (see “Settings” section below for details).

Settings

Setting	Description	Default
Remote address	Remote address to connect to. Can be specified via IPv4 (`127.0.0.1`), IPv6 (`::1`), or a domain name (`localhost`). Remote address can be suffixed with the remote port after a colon, e.g. `ioninja.com:443`.
Remote port (default)	Remote port to connect to in cases when a port is not explicitly specified in Remote address.	80
Reconnect	Attempt to reconnect when connection is dropped by the remote node.	False
Reconnect timeout	The delay between reconnect attempts.	3000
Use local address	Bind socket to the specified local address.	False
Adapter	Local network adapter to bind to. Pick one from the list of installed network adapters (or bind to all installed `IP4` or all `IP6` adapters at once).	Auto
Local port	Local port to bind to. Setting this to `0` auto-selects an available port.	8080
Reuse address	Allow multiple sockets to share the same local address. Maps to the `SO_REUSEADDR` socket option. Please note, the support and details of implementation for this option are highly platform-specific.	False
TCP Nagle algorithm	Delay transmission to reduce the number of small TCP packets. Maps to the `TCP_NODELAY` socket option.	False
TCP reset	Drop TCP connections abruptly with a TCP RST packet. Maps to the `SO_LINGER` socket option.	False
TCP keep-alives	Detect connection loss with TCP keep-alive probes. Maps to the `TCP_KEEPALIVE` socket option.	False
User name	User name for SSH authentication.
User authentication	SSH authentication method (password or private key)	Password
Private key file	Private key file for SSH authentication.
Remember last password	Re-use the last entered password during subsequent connect attempts.	True
Process type	Type of requested SSH process. See available options.	shell
Process parameter	Parameter to pass to the remote process.
Pseudoterminal	Type of requested pseudoterminal (PTY). Read more about psuedoterminal types here.	xterm
Read block size (B)	The size of each individual read block submitted to the underlying transport.	4KB
RX buffer size (B)	The full size of the incoming data (RX) buffer. Affects read throughput.	16KB
TX buffer size (B)	The full size of the outbound data (TX) buffer. Affects write throughput.	16KB
Keep read block size	Don’t merge read blocks in RX buffer. Incoming data blocks coming in quick succession can be merged together so that IO Ninja writes them to log as a whole. When this option is set to `True`, blocks are written to the log without merging, i.e., exactly as they are received from the underlying transport.	False
Keep write block size	Don’t merge write blocks in TX buffer. Outbound data blocks sent in quick succession can be merged together before submission to the underlying transport. When this option is set to `True`, blocks are submitted to the transport without merging, i.e., exactly as they are sent by the Transmit or Script panes.	False
RX buffer full notifications	Toggle warnings in log about the incoming data (RX) buffer getting full.	False

Process Type Options

Option	Description
shell	Starts an interactive terminal session (e.g., ssh user@host).
exec	Runs a single command remotely (e.g., ssh user@host “ls”).
subsystem	Launches a predefined service like SFTP (e.g., sftp user@host).
