This article will explain in detail how to install NistNet under CentOS. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

1. Operating system CentOS installation:

After many times of installation and testing, the CentOS installation is installed on the full CD, because the kernel needs to be compiled to install nistnet.

2. Download the relevant software packages after CentOS is installed

Linux-2.6.18.8.tar.gz

Download address: http://www.kernel.org/pub/linux/kernel/v2.6/

Nistnet.2.0.12c.tar.gz

Download address: http://www-x.antd.nist.gov/cgi-bin/nistnet-distribution

3. Compile the kernel

# tar zxvf linux-2.6.18.8.tar.gz

# cd / usr/src/

# ln-s / root/ linux-2.6.18.8/ linux

# cd linux

# make mrproper / / Delete unstable .o files and .config files

# make menuconfig

Device Drivers->

| | Character devices-- > |

| | Enhanced Real Time Clock Suppot-- M / / Press M key to set |

# make dep / / Link program code and function library

# make clean / / Delete unnecessary modules

# make bzImage / / generate kernel files

# cp arch/i386/boot/bzImage / boot/vmlinuz-2.6.18-8_new / / Note the correct path

# make modules / / compile plug-in module

# make modules_install / / install the compiled module

# make install

# mkinitrd / boot/initrd-2.6.18-8_new.img 2.6.18.8

# vi / boot/grub/grub.conf / / add launch items as follows:

Title Centos (2.6.18-8_new)

Root (hd0,0)

Kernel / vmlinuz-2.6.18-8_new ro root=/dev/VolGroup00/LogVol00 rhgb quiet

Initrd / initrd-2.6.18-8_new.img

/ / pay attention to default=x (x is the option added above, starting with 0)

# init 6

4. CentOS install NistNet

# tar zxvf nistnet.2.0.12c.tar.gz

# ln-s nistnet-3.0a nistnet

# cd nistnet

#. / configure

# make

# * error will appear here and need to be modified as follows * *

1), ~ / nistnet-3.0a/kernel/knistnet.c

Find lines 916,961,972 and 1003, and add the parameter NULL, such as:

Return ippt- > func (skb, dev, ippt); à return ippt- > func (skb, dev, ippt,NULL)

2), / lib/modules/2.6.18.8/build/include/asm/rwsem.h

Find lines 104, 156, 198, 224, 249 and comment them out (I don't know the exact meaning of the assembly), such as:

LOCK_SECTION_START (") à / / LOCK_SECTION_START (")

3), / lib/modules/2.6.18.8/build/include/asm/semaphore.h

Find lines 105, 130, 155, 179 and comment them out (I don't know the exact meaning of the assembly), such as:

LOCK_SECTION_START (") à / / LOCK_SECTION_START (")

# * recompile * *

# make

# make install

5. Test whether the installation is successful

# cd ~ nistnet/

#. / Load nistnet

# cnistnet-u

Check the situation of ping:

[root@localhost nistnet] # cnistnet-a 192.168.2.2 192.168.2.11-- delay 50

Addnistnet: 192.168.2.2 cos 0 to 192.168.2.11 cos 0 (cos 0)
