A device that analyzes traffic has been deployed in the previous period and needs to mirror the port's traffic to a single copy of the server's NIC.Because the Juniper Operation command is unfamiliar, the online command is also relatively few. So write a blog record.EXthe port mirroring of the switch allows the port to be in traffic, or the outbound traffic is mirrored separately, andethernet-switchingof theFirewall Filter, you can specify that eligib

Today to a customer in the Juniper SSG140 firewall debugging L2TP VPN, when established, the client asked me to establish 350 L2TP VPN users above the firewall, immediately dumbfounded, if manually set up 350 L2TP VPN users that will not be exhausted! A small program was written specifically to generate the L2TP VPN user command (pictured below) for the user's needs. With this applet, you need to fill in the relevant parameters, such as how many us

1 Juniper Router enters configuration mode for the first time, you must set the login password, or the commit prompts for a root-authentication password, and the login password method is set as follows: Root#set system Root-authentication Plain-text-password New Password: (the password here must be a combination of numbers + letters, at least 6 digits) Retype new Password: After the setup is complete, the root login password is set successfully.

Juniper DOS ClassificationFirst, the network DOS1.SYN floodingUse three handshake for spoofing attacksA sends a SYN fragment to B, B responds with a syn/ack fragment, and a responds with an ACK fragment.The source IP in the Syn fragment sent by this is an unreachable address, so the response sent by B will time out,This creates a SYN flooding attack that fills the host memory buffer and the host will not be able to handle the newA TCP connection reque

To ensure the high availability of network applications, two firewall devices of the same model can be deployed at the edge of the network to be protected during the deployment of Juniper firewall to implement HA configuration. Juniper firewall provides three high-availability application configuration modes: master-slave mode, master-master mode, and dual-master redundancy mode. Here, we only describe the
