History
Usage
SSH requires an SSH authentication key. You can generate one or allow MSS to generate
one. The first time an SSH client attempts to access the SSH server on an MX, the MX
automatically generates a 1024-byte SSH key. If you want to use a 2048-byte key instead, use the
crypto generate key ssh 2048 command to generate one.
The maximum number of SSH sessions supported on an MX is eight. If Telnet is also enabled, the
MX can have up to eight Telnet or SSH sessions, in any combination, and one Console session.
