    Firewall model: Juniper Netscreen-25 (NS-025B-003)

     

    The firewall has already worked for serveral years. Recently, I can't access the web interface and telnet.

     

    Thank you

    Hello.

     

    If the issue resolves after a reboot, I would venture to guess that the firewall is running out of sockets...

     

    There were issues in earlier versions of ScreenOS...

     

    sometimes manually clearing the sockets worked, sometimes it didn't.

     

    http://kb.juniper.net/InfoCenter/index?page=content&id=KB21096  might be of help.

     

     

    Regards,

    Sam

    Many thanks samc and rcojunos. I reboot the system can solve the problem.

     

    First i connect with rj-45 serial port login the system.

    Next backup the configuration and software image with following command:

         save config from flash to [tftp <address> | pcmcia | slot1} <filename>
         save software from flash to [tftp <address> | pcmcia | slot1] <filename>
    Than, type 'reset' and 'y' to reboot the system.
    Final, I can access the webUI.
     
    Thanks,
     
    Lou

    Have you tried reconfigure the services (telnet+web)? A reboot should be enough unless something on the config is blocking the access.
