Today we recommend a good open source routing operating system---Vyos, is also my personal favorite of a soft router. Vyos is based on the Debian Gnu/linux, which provides similar operations to other Junos-like iOS, Juniper, and is particularly comfortable to configure, especially with commands such as compare, rollback, etc. Easy to compare configuration and error rollback, won my heart.As a result of the use of Mikrotik RouterOS, in the process of u

Two sets of juniper data cores to prevent loop occurrence by configuring Mc-lagI. BACKGROUNDThere are two sets of data core switches deployed in two different network rooms, the current state is a single-mode fiber three-layer network interconnection, but the business unit put forward a new network requirements, to build three network segments, gateway to enable the core switch in a-block room, C block room also to use these three network segments, fo

providers are developing some technologies and establishing partnerships to help network administrators master IT energy management tools. Both Juniper and Cisco have established partnerships with JouleXr, a non-Agent Energy Management supplier, to monitor, analyze, and control the energy consumption of IT infrastructure and other enterprise devices. JouleX integrates Juniper's Junos Space SDK to monitor and analyze the energy consumption of any devi

-subnet, enter the IP address 172.16.1.0, and click OK. The VPNGateway virtual machine needs to add another nic. in Linux, set each Nic according to the following table, and select the network corresponding to the NIC in the VM settings. The network card 0 of VPNGateway belongs to VMNet0, and the Network Card 1 belongs to vmnet2. The default Nic of network adapter 1 is 192.168.2.1. In addition, the XP host is automatically located in VMNet0 and does not need to be set. Machine name

Requirements: Use the Ubuntu 8.04 Server version of the syslog record Juniper isg1000 log for 3 months. 1. Allow syslog to record external logs Modify the/ETC/DEFAULT/SYSLOGD to change the syslogd= "" to syslogd= "-R" 2. Define external log types Modify the Juniper isg1000 log definition so that its generated log is defined as LOCAL7 and send logs to the Ubuntu server. 3. Define log files In view of

do ISPs control and manage their networks while entering the light internet age? Speed can kill! Control is important if you are playing a car at a 15m.p.h speed on Disney's Autotopia, but you're not going to get hurt. On the other hand, if you find yourself on the Indianapolis500, then, the high performance of the brakes, tires, and driving the controls provided, will be very important for your survival. This article will assume that we have entered the era of optical Internet, high-performa

Reasons and solutions for the loss of network card of Linux virtual machine under Hyper-V virtualization The company has implemented virtualization, all using Microsoft Windows R2 Enterprise with Hyper-V makes the cluster run Hyper-V virtual machine. This is a good thing, save resources, centralized management, power saving, deployment ultra-fast, the key is to live migration. We use the Dell Md3000i enclosure as a clustered shared disk, which is iSCSI-based Gigabit Ethernet network storage, a

Security is critical for Linux/unix production servers and is a basic lesson for every system administrator. This article is "Plainly your Linux Server" series of the fourth, all listed below is about the basic Linux server settings, and strive to use the simplest language to explain the basic Linux server security settings, especially for the novice, if the security of the Linux server has higher requirements, It is recommended to work with a hardware firewall.First, the hardware protection of

Pierson said that multiple logon failures could also mark an attack and check for logins that use Non-existent user accounts, which usually indicates an attempt to guess the user's account information and to obtain authentication. Similarly, trying to get a successful login at work time may also indicate that this is not true for employees accessing data. Companies should investigate this. 5, the volume of database reading surges When an attacker invades an enterprise and tries to ooze inform

Unfortunately, Microsoft's software engineers are still not implementing it in the system, even though Microsoft has helped in writing the code for send. And some of the major network equipment suppliers, such as Cisco and Juniper Network, have implemented the support for send. It is hoped that Microsoft will be able to implement the send support in all of its operating systems in the
