NETGEAR 8800 User Manual enable telnet You must be logged in as an administrator to configure the virtual router(s) used by Telnet and to enable or disable Telnet. Disconnecting a Telnet Session A person with an administrator level account can disconnect a Telnet management session. If this happens, the user logged in by way of the Telnet connection is notified that the session has been terminated. To terminate a Telnet session: 1. Log in to the switch with administrator privileges. 2. Determine the session number of the session you want to terminate by using the following command: show session {{detail} {}} {history} 3. Terminate the session by using the following command: clear session [history | | all] Using Secure Shell 2 Secure Shell 2 (SSH2) is a feature of the XCM8800 software that allows you to encrypt session data between a network administrator using SSH2 client software and the switch or send encrypted data from the switch to an SSH2 client on a remote system. Configuration, image, public key, and policy files can be transferred to the switch using the Secure Copy Protocol 2 (SCP2) or the Secure File Transfer Protocol (SFTP). The XCM8800 SSH2 switch application works with the following clients: Putty, SSH2 (version 2.x or later) from SSH Communication Security, and OpenSSH (version 2.5 or later). OpenSSH uses the RCP protocol, which has been disabled from the XCM8800 software for security reasons. Therefore, OpenSSH SCP does not work with the XCM8800 SSH implementation. You can use OpenSSH SFTP instead. The switch accepts IPv6 connections. Up to eight active SSH2 sessions can run on the switch concurrently. If you enable the idle timer using the enable idletimeout command, the SSH2 connection times out after 20 minutes of inactivity by default. If you disable the idle timer using the disable idletimeout command, the SSH2 connection times out after 61 minutes of inactivity. If a connection to an SSH2 session is lost inadvertently, the switch terminates the session within 61 minutes. For detailed information about SSH2, see Chapter 17, Security. Using the Trivial File Transfer Protocol XCM8800 supports the Trivial File Transfer Protocol (TFTP) based on RFC 1350. TFTP is a method used to transfer files from one network device to another.
