Install Linux in the school room Lenovo HDD Protection, and configure the Ruijie client

In recent days has been in the computer room brush questions, air conditioning is very comfortable. But the computer room is full of Windows system, not very good, very diaphragm should be human.
have been planning to change a system, just finally fix the network problem, later with the computer can be happy to.

Lenovo hard disk protection system under the U-disk installation

Here I would like to start the U disk is no limit, the result of Lenovo hard disk protection has been in the right with me.
The main point is these two points, which I had never thought of before:

1. Hard drive protection cannot be removed by emptying the hard drive
2. Fixed priority boot drive protection

Guess this hard drive protection is written on the NIC (The hard drive has been cleaned by me, but the hard disk protection still exists).
Do not know how this hard disk protection is written on the network card, but do not know why the network card fixed priority boot (guess is to restore the BIOS settings).
Finally, try the uefi boot only , the result is the U disk can be started.
Guess Nic this thing only supports legacy boot.
Then the LIVECD can be installed directly.

Network settings

This is the most uncomfortable place for me, a basic knowledge I actually did not realize. Room and office This kind of local IP is generally static. (Wry smile
Let's talk about how static IP is configured, and how to authenticate with Ruijie.
Static IP Settings
Here in CentOS, for example, the first must have a network card and driver, here the network card model is this
You have to know the NIC interface name

$ lspci | grep Network00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (Lewisville) (rev 04)$ ip link show2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000    link/ether 44:37:e6:c8:d0:af brd ff:ff:ff:ff:ff:ff

Set static IP, edit/etc/sysconfig/network-scripts/ifcfg-xxx
XXX corresponds to the NIC interface, here is eno1.
Note just configure the following things just fine. The computer on my left is number 65th, so IP is 192.168.3.65.

BOOTPROTO=staticONBOOT=yesDNS1=202.117.80.2IPADDR=192.168.3.65NETMASK=255.255.255.0GATEWAY=192.168.3.254

Then restart the network to connect Ruijie.
Note that the IP settings in Ruijie should be the same as above, canceling DHCP.

$ service restart network$ sudo mentohust

The internet is so simple, the basic knowledge I did not realize, simply.

The process of suffering

I have to write about these pains, or I will complain.

USB stick Boot problem

Last weekend in the computer room bored, ready to install a archlinux, configuration under the environment.
Results The Lenovo hard disk protection priority starts, detects the USB stick does not allow to enter the system.

OK, find a way to get into the BIOS and set the boot order.
A disorderly press, found F12 can enter the boot Sequence settings interface, through this into the BIOS.
Without turning on UEFI boot only, the result is that you can't get into the USB flash drive.
Finally, the problem was solved by speculation.

Network Problems

Archlinux.iso only support network installation system, into the LIVECD found no net.

OK, copy a Ruijie client, authentication is good.
The result is to set up the dynamic allocation of IPdirectly, found that authentication is successful, but is not getting IP?

Yes, ask the big guy, try the dial- up connection .
found that the computer room network is not modified, meaning that there is no dial-up connection.

OK, buy a wireless network card connected to the campus WiFi headquarters.
Bought found Linux no driver (my good melon-_-
Check a half-day drive module, each module according to a test, are useless.
Finally consider ndiswrapper install Windows driver.
Source download good, found archlinux default do not let use make (_make)
For Ubuntu, install the system found there is no make, even GCC have no (surprised the Ubuntu developers and users are God-man ...
The alternative is to simply use the ISO local source for CentOS.
NDISwrapper compiled successfully, Windows driver installed successfully, the module was loaded successfully, that is, the NIC interface cannot be found. (Windows drivers are extracted from the sr0 of the NIC and are absolutely matched.)
I was desperate, so I played a training game and went through two water problems more desperate.

Today early back to the dormitory, eat a good on the road to the computer room.
Specially, suddenly want to understand how dynamic IP is allocated, so open the Windows Ruijie client, found that this is static IP at all.
So today is the most happy day of the month, solved the problem of half a month not solved haha.
