Linux official version with 802.1x authentication

Article title: linux official version with 802.1x authentication. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Many schools use the Shida-Ruijie 802.1 certification system. now (in fact, last month) Ruijie has launched the linux client authentication program, called xrgsu.
　　
I downloaded one and can use it. however, libpcap is required. so, this may be a little troublesome, because most of the downloaded files on the Internet compile LIBPCAP. a. I 've been working on it for A long time. I finally see A description, as shown below:
-----------------------------------------------------
2. Compile and install the libpcap library
　　
The hypothetical libpcap-0.7.2.tar.gz is stored in the/home/andy directory. The procedure is as follows:
[Root @ t113/] # cd/home/andy
[Root @ t113 andy] # gunzip libpcap-0.7.2.tar.gz
[Root @ t113 andy] # tar-xvf libpcap-0.7.2.tar
[Root @ t113 andy] # cd libpcap-0.7.2
[Root @ t113 libpcap-0.7.2] #
　　
Note (speak out loud ~~), The function is compiled as a static function library here, but you need to share the function library (dynamic function library) when compiling DNSTOP later ). So we need to modify the Makefile. in file under the libpcap-0.7.2 Directory, open the file to find the following statement:
[Code: 1: 248ab9a8fe] all: libpcap. a (row 96th)
　　
Libpcap. a: $ (OBJ)
@ Rm-f $ @
Ar rc $ @ $ (OBJ)
$ (RANLIB) $ @ [/code: 1: 248ab9a8fe]
To:
[Code: 1: 248ab9a8fe] all: libpcap. so
　　
Libpcap. so: $ (OBJ)
@ Rm-f $ @
# Ar rc $ @ $ (OBJ)
Gcc $ (OBJ)-shared-o libpcap. so
# $ (RANLIB) $ @ [/code: 1: 248ab9a8fe]
　　
Find the following statement:
[Code: 1: 248ab9a8fe] install :( lines 139th)
[-D $ (DESTDIR) $ (libdir)] | (mkdir-p $ (DESTDIR) $ (libdir); chmod 755 $ (DESTDIR) $ (libdir ))
$ (INSTALL_DATA) libpcap. a $ (DESTDIR) $ (libdir)/libpcap.
$ (RANLIB) $ (DESTDIR) $ (libdir)/libpcap. a [/code: 1: 248ab9a8fe]
　　
To:
[Code: 1: 248ab9a8fe] install:
# [-D $ (DESTDIR) $ (libdir)] | # (mkdir-p $ (DESTDIR) $ (libdir); chmod 755 $ (DESTDIR) $ (libdir ))
# $ (INSTALL_DATA) libpcap. a $ (DESTDIR) $ (libdir)/libpcap.
# $ (RANLIB) $ (DESTDIR) $ (libdir)/libpcap.
Cp libpcap. so/usr/lib/[/code: 1: 248ab9a8fe]
　　
Done! Start compilation:
[Root @ t113 libpcap-0.7.2] #./configure -- prefix =/usr
[Root @ t113 libpcap-0.7.2] # make
[Root @ t113 libpcap-0.7.2] # make install
　　
We can breathe a sigh of relief.
------------------------------------------------
Xrgsu is a binary program, which can be copied to/usr/bin.
　　
Download a connection http://seal.blogchina.com/
　　
Download and change the suffix to .tar.gz
　　
More than 500 kb. if it cannot be uploaded, upload a single file, decompress it, replace it with the original file, and then compile it. of course, if you download it, you can compile libpcap. so.
　　
The original file can be easily searched to (libpcap-0.8.3), xrgsu in ftp://ftp.jnu.edu.cn/student
