24-Port 10/100/1000 Gigabit Switch with Webview and PoE
Security Tab - SSH Settings
The Secure Shell (SSH) includes server/client applications that can provide remote management access to the
Switch and act as a secure replacement for Telnet.
When the client contacts the Switch through the SSH protocol, the Switch generates a public-key that the client
uses along with a local user name and password for access authentication. SSH also encrypts all data transfers
passing between the Switch and SSH-enabled management station clients, and ensures that data traveling over
the network arrives unaltered.
Note that you need to install an SSH client on the management station to access the Switch for management
through the SSH protocol. The Switch supports both SSH Version 1.5 and 2.0.
SSH Server Status. Allows you to enable/disable the SSH server on the Switch. (Default: Disabled)
Version. The Secure Shell version number. Version 2.0 is displayed, but the Switch supports management access
via either SSH Version 1.5 or 2.0 clients.
SSH Authentication Timeout. Specifies the time interval in seconds that the SSH server waits for a response from
a client during an authentication attempt. (Range: 1-120 seconds; Default: 120 seconds)
SSH Authentication Retries. Specifies the number of authentication attempts that a client is allowed before
authentication fails and the client has to restart the authentication process. (Range: 1-5 times; Default: 3)
SSH Server-Key Size. Specifies the SSH server key size. The server key is a private key that is never shared
outside the Switch.The host key is shared with the SSH client, and is fixed at 1024 bits. (Range: 512-896 bits;
Default:768)
