Description
Use the SSH program to open a connection between a local router or switch and a remote system and execute commands on the remote system. You can issue the ssh command from the Junos OS CLI to log in to a remote system or from a remote system to log in to the local router or switch. When executing this command, you include one or more CLI commands by enclosing them in quotation marks and separating the commands with semicolons:
Options
host | — | Name or address of the remote system. |
bypass-routing | — | (Optional) Bypass the normal routing tables and send ping requests directly to a system on an attached network. If the system is not on a directly attached network, an error is returned. Use this option to ping a local system through an interface that has no route through it. |
inet | inet6 | — | (Optional) Create an IPv4 or IPv6 connection, respectively. |
interface interface-name | — | (Optional) Interface name for the SSH session. (This option does not work when default-address-selection is configured at the [edit system] hierarchy level, because this configuration uses the loopback interface as the source address for all locally generated IP packets.) |
logical-system logical-system-name | — | (Optional) Name of a particular logical system for the SSH attempt. |
routing-instance routing-instance-name | — | (Optional) Name of the routing instance for the SSH attempt. |
source address | — | (Optional) Source address of the SSH connection. |
v1 | v2 | — | (Optional) Use SSH version 1 or 2, respectively, when connecting to a remote host. |
