Nevertheless, access us[...]

2.1.2 Remote connection The console interface can also be accessed remotely from any computer on the same subnet using either Telnet or SSH (under the hypothesis that the rele vant service is running and enabled for the selected user). TELNET Telnet provides basic user authentication. The SNMP/Web adapter uses the standard telnet port. To start a T[...]

• Most SSH clients display the host key fingerprint at the sta rt of the session. Make sure the fingerprint shown matches the SNMP/Web adapter fingerprint (see Encryption section for details on figuring out the SSH fingerprint) • A login window should then be available in a few seconds. The default username (login) and password are ge and ge 2.[...]

2.2 COMMAND LIST The various commands are split in di fferent groups, depending on the involved funct ionality, and are listed here in accordance with their group classification.
