Introduction and installation of ROS soft routing

The author is a network engineer, in the enterprise all day with firewalls, routers, switches dealing with. In an enterprise, in order to protect users ' normal Internet, the download of speed limit users, need to use flow control and behavior management equipment; For network security, users need to be authenticated, in order to carry out Soho mobile office, so that the external network users can login OA, ERP and other intranet systems, need to add a dedicated VPN equipment. To achieve the above functions, the need for professional firewall, routers, flow control, VPN equipment, each device is expensive, at tens of thousands of yuan. For a small and medium-sized enterprise, it is indeed a very large expenditure. Therefore, here I strongly recommend a soft route, Router OS, referred to as Ros.

The so-called soft routing, is relative to the hard road Origin said. Hard routing is a hardware router, which is what we often call Cisco, Huawei's route, the factory is an iron box, which integrates a dedicated CPU and ASIC chip, has its own dedicated operating system, such as Cisco's iOS and Huawei's VRP. has a fast processing speed, good after-sales service, has a special technical manual and after-sales support team and other characteristics. The soft route, in fact, is a routine by the software system, the routing system installed in the ordinary X86 server or PC can be. I know the soft route has the sea Spider, the league, and so on, the most powerful will be the Ros.

Ros is a Linux-based router system produced by a small country in eastern Europe called Mikrotik, which makes it possible to turn an ordinary PC into a professional router, almost all the needs of a small and medium-sized business network. Ros features include: NAT, PPPOE (client, server), remote VPN and site-to-site VPN, QoS rate control, firewall features, multi-egress redundancy and load, Policy Routing, RIP and OSPF dynamic routing, authentication and billing, VRRP, NTP. The key is that Ros is inexpensive, which allows many small and medium-sized businesses to achieve both the required functionality and it savings.

Now some second-hand ISPs that resell bandwidth are also using ROS. They lease the bandwidth to first-class operators, and then contract some communities to provide PPPoE dialing and speed-limiting functions to users in the community by erecting Ros. Some of the online cases have a Ros band of more than 20,000 terminals, which shows the stability and reliability of Ros.

The characteristics of ROS are summarized as follows:

1. Price Advantage

   General hardware routers are expensive, such as Cisco's enterprise-class routers typically cost tens of thousands of yuan.

2. System stability

   Based on the Linux kernel, the underlying system is secure and does not have as many vulnerabilities as Windows systems to run reliably over the long term.

3. Support programming

   Ros is a Linux kernel that supports scripting and can implement a variety of complex functions.

4. Powerful features

   A ROS can be routers, firewalls, flow control, authentication devices, VPN devices, can achieve dynamic routing, data forwarding, NAT, traffic control, PPPOE, Web Authentication, PPTP, L2TP VPN and other functions, can be said to be really powerful.

5. Wide application area

   Ros can be used in enterprises, internet cafes, small operators and other places. There are many internet cafes and small operators in the use of ROS, mature cases have been many.

Installation of Ros:

If a reader company needs to use Ros, they can purchase their official hardware products directly. It is a box with integrated CPU, chip and hard disk, and the software of ROS is installed on the hard disk. Or the reader will prepare a server or a stable pc, and buy a set of ROS for installation. Ros is a commercial software that needs to be paid for and needs to be purchased license for activation. Ros is based on hard drives to calculate license, so Ros cannot replace the hard drive after it is installed.

I am using the older Ros version, 3.2, and now the latest version is the same as the installation steps.

By default, only the "System" option is selected, these are ROS modules, such as PPP is the module in which PPTP, PPPOE,DHCP is the Dynamic Host Allocation protocol, which functions need to be selected. Press "A" on the keyboard to select all and press "I" (install) for installation.

Ask if you want to keep the old configuration, select Y. After the input is completed, it will be restarted, and the following interface is entered after reboot.

The default user name is admin and the password is empty. Enter to sign in. To this, the installation of Ros is complete.
