RouterOS installation Configuration

RouterOS installation configuration-Linux Enterprise Application-Linux server application information. For more information, see the following section. 1. RouterOS installation:

In the RouterOS installation configuration menu, use the arrow key to control the cursor, use the space key to select or discard the option, and press I to confirm the installation.

We generally only need the basic system for fiber-optic access. If it is adsl or modem dialing, We need to select ppp. I don't need to say dhcp. hotspot is the kind of community Internet access, when connecting to the Internet, you need to enter the account and password on the webpage to access the Internet. isdn is another dialing method. LCD is a small LCD display, and ntp is the time server and client, routing is an orthodox routing protocol. telephony is H232, which is related to audio and video. If you find a video connection problem, you can install this option, web-proxy web proxy, note that this is not recommended unless necessary. Many Web pages are not suitable for caching (for example, those password pages), and others have no value for Internet cafes (arlan, gps and so on are related to wireless devices. Do you need to explain ups ?)

We recommend that you install system and advanced-tools (advanced menu). You can choose dhcp or telphony as needed.

I usually choose these items: system. ppp advanced-tools security web-proxy

To facilitate learning, you can install them all.

Start by I
Press y twice

After selecting and installing the component, press "I" to enter the installation interface. Here, the system will ask you two (Y/N) about whether to clean up the hard disk or not, all "Y" is enough. After the installation is complete, you will be asked to REBOOT. Press enter.

Let's take a look.

System "Press ENTER"
License "Press ENTER"
Print "enter"

You can see the above registration information, oh, level 6, ISP level, very good.

The FileSystem of RouterOS is not public. You can only use several restricted commands. You can enter "?" whenever you don't know what to do. "/" Is similar to the dos "cd ". The preceding command is similar to "enter the system directory, then enter the license directory, and then execute the print command ".

Now let's configure the NIC

Enter "setup". In fact, you can abbreviated RouterOS commands as the first three letters. For example, you only need to enter "set.

The setup menu is simple.
R-reset

L-load driver

A-configure the NIC

D-configure the DHCP Client

S-configure the DHCP server

P-configure pppoe

T-configure pptp

X-exit menu

If you find that your configuration is wrong, the simplest way to flatten is set-r, or directly "reset.

Check it out.

Well, now we select "a" to configure the NIC

Here is another menu

A-add an address

G-configure the Default Gateway

X-exit menu

After "a" is selected, he will ask you to configure the NIC. By default, he will load etner2 first. You need to change 2 to 1. Note that, if he does not display et22. instead, he directly enters the next interface, that is, he recognizes only one network card. enter the Intranet ip address and mask,


2017100000000255 = 11111111.11111111.111111.11111111 (here there are 32 1, that is, 32)

255.255.255.0 = 11111111.11111111.111111.00000000 (this is 24)

So enter 192.168.0.X/24

Set it to 192.168.0.1/24.

Okay.

The above steps have completed linux ros installation.
