juniper ips

Because the author recently encountered such a situation, the number of servers to do networking planning, the client side gives a limited amount of IP,Not enough for each host to be assigned to IP, but I think again, not necessarily every service must use the DCN network address,So I think I can configure the network card that must use the DCN network address two IP, a DCN network address, a private IP address we define ourselvesThe author takes the operating system under VMware Virtual machine

Recently do the system performance optimization encountered a problem, after the solution to share to everyone.When we establish a connection through the socket, if our computer cannot connect with the specified site, then this will cause the system to be stuck on the socket connect method,We all know that the socket to establish a connection requires three handshake, the computer sends a message header to the server, the server returns, this time the socket basic connection is successful, but i

1. Test topology: Note: The TCP Reset command cannot be issued from the original sensor port of the IPs because of the constraints of the simulated environment, so the test emits a TCP reset with the IPs other interfaces. 2. Basic configuration: R1: Interface fastethernet1/0 IP address 10.1.1.1 255.255.255.0 No shut R2: Interface fastethernet1/0 IP address 10.1.1.2 255.255.255.0 No shut R3: R3

=ethernetOnboot=yes Two, a single network adapter to bind multiple IPsSometimes we need to configure multiple IPs on a NIC, for example, in the example above, we also need to configure IP 192.168.168.2 and 192.168.168.3 for eth0. Then you need to create a new two configuration file under/etc/sysconfig/network-scripts:ifcfg-eth0:0 content is as follows: device=eth0:0Bootproto=staticipaddr=192.168.168.2netmask=255.255.255.0Onboot=yes

The company has become a Symantec senior partner, I will be responsible for Symantec and Kaspersky Pre-Sales Technology and after-sale support, a preliminary understanding of the 7100 series and the SxS of the new Sysmantec mode, think it is very good, Especially ids/ips on the solution, deeply admired.

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
