In some circumstances, when the administrator wants to make configurations without interruption from the users that have logged in through other user interfaces, the administrator can execute the command to release the connections established on the specified user interfaces. You cannot use this command to release the connection that you are using. Lock the current user interface lock Available in user view By default, the current user interface is not locked. Send messages to the specified user interfaces send { all | num1 | { aux | vty } num2 } Available in user view 56 Web login Web login overview The device provides the web-based network management function to facilitate device operation and maintenance. With this function, the administrator can visually manage and maintain network devices through web-based configuration interfaces. Configuration guidelines • The web-based network management function supports the operating systems of Windows XP, Windows 7 and Windows Vista. • The web-based configuration interface supports Microsoft Internet Explorer 6.0 SP2 and higher, and the explorer must support and be enabled with JavaScript. • The web-based configuration interface does not support the Back, Next, Refresh buttons provided by the browser. Using these buttons may result in abnormal display of Web pages. • When the device is performing the spanning tree calculation, you cannot log in to or use the web interface. • The Windows firewall limits the number of TCP connections. When you use IE to log in to the web interface, sometimes you may be unable to open the web interface. To avoid this problem, turn off the Windows firewall before login. • If you log in to the device through the web interface after the software version of the device changes, HP recommends you to delete the temporary Internet files on IE; otherwise, the web page content may not be displayed correctly. Logging in to the firewall by using the default web login information The firewall comes with the default web login information. You can log in to the web interface of the firewall by using the following default login information: • Username: admin • Password: admin • IP address of the management Ethernet interface: 192.168.0.1. For the interface number, see the corresponding installation guide or card manual of the firewall. Follow these steps to log in to the firewall through web: 1. Connect the management interface of the firewall to the network port of the PC through a crossover Ethernet cable. 2. Change the IP address of the PC to one that is within the network segment 192.168.0.0/24 (except for 192.168.0.1), for example, 192.168.0.2 so that the PC and the firewall can communicate with each other. 57 3. On the PC, launch the browser, type the IP address 192.168.0.1 in the address bar, and press Enter to enter the web login page, as shown in Figure 41. Enter username admin, password admin, and the verification code, select a language (English), and click Login. Figure 41 Web login page CAUTION: • To get a new verification code, click on the verification code picture. • Up to five users can concurrently log in to the device through the web interface. Modifying the default web login information Log in to the firewall, and configure as follows: 1. Create a Telnet user, set the username to userA, password to 123456, and user privilege level to 3. [HP] local-user userA New local user added. [HP-luser-userA] servce-type telnet [HP-luser-userA] password simple 123456 [HP-luser-userA] authorization-attribute level 3 2. Add an interface into the management zone in hidden command line view to enable the firewall to communicate with a PC through this interface, and then you can log in to the firewall through this interface. [HP]_ Now you enter a hidden command view for developer's testing, some commands may affect operation by wrong use, please carefully use it with our engineer's direction. [HP-hidecmd] zone add interface GigabitEthernet0/1 to management Configuring the web login function If the web function is disabled, log in to the device via the console port, and perform the following configuration: • Enable HTTP or HTTPS service • Configure the IP address of the management Ethernet interface • Configure a username and password The device supports the following web login methods: 58 • HTTP login—The Hypertext Transfer Protocol (HTTP) is used for transferring web page information across the Internet. It is an application-layer protocol in the TCP/IP protocol suite. The connection-oriented Transport Control Protocol (TCP) is adopted at the transport layer. Currently, the device supports HTTP 1.0. • HTTPS login—The Secure HTTP (HTTPS) refers to the HTTP protocol that supports the Security Socket Layer (SSL) protocol. HTTPS uses SSL to encrypt the data exchanged between the HTTPS client and the server to ensure data security and integrity. You can define a certificate attribute-based access control policy to allow legal clients to access the de...
