ssh <value>
AresC640 Atlas840 H5-Rail M10-Smart M2 M20 RS420 RXL15000 SDE SDE-11k

Hostname and address to SSH to

Values:

  • [user@]host – Hostname and address to SSH to

Options:

escapechar <txt>

Sets the escape character.

Values:

  • txt – Escape character.

force-version-1

Forces ssh to try protocol version 1 only

option <value>

Additional SSH options

Values:

  • value – Optional argument

host-key-algorithms <id>

Specifies the host key signature algorithms that the client wants to use in order of preference

Values:

  • id – Choose an algorithm

syslog

Send log information using the syslog system module.

cipher <id>

Selects the cipher specification for encrypting the session.

Values:

  • id – Chose cipher.

mac <id>

Specifies the MAC (Message Authentication Code) algorithm to use

Values:

  • id –

    Specifies the MAC (Message Authentication Code) algorithm to use

    The MAC algorithm is used for data integrity protection. The algorithms that contain “-etm” calculate the MAC after encryption (encrypt-then-mac). These are considered safer and their use recommended. Notice that some cipher algorithms already offer authentication (the ones that are named like “…@openssh.com”). Those algorithms will make the SSH clients to ignore the MAC setting.

quiet

Supress most of warning and diagnostic messages.

private-key <file>

Private key to use when logging in remotely

Values:

  • file – Private key to use when logging in remotely

verbose

Verbose mode.

port <u32>

Specify a port number to connect

Values:

  • u32 – Port to connect

local-address <value>

Use local IP address as the source address of the connection.

Values:

  • value – Local IP address

force

Force connection. Remove the key if exists in known_hosts file

force-ipv6

Forces ssh to use IPv6 addresses only

key-exchange <id>

Specifies the available KEX (Key Exchange) algorithms

Values:

  • id – Specifies the available KEX (Key Exchange) algorithms

vrf <id>

Set source address to a specific VRF

Reference:

system vrf <id>

Values:

  • id – VRF name

force-ipv4

Forces ssh to use IPv4 addresses only

force-version-2
