The path to linux is always a treasure.

My path to linux is always at odds-general Linux technology-Linux technology and application information. For more information, see the following. After returning from the previous night's study, I decided to implement linux, complete two tasks, set a permanent mac address, and install a linux version of ruijie. Mac Address Permanent settings, this is easy to achieve,/etc/sysconfig/networking/devices/ifcfg-eth0, add a temporary modify mac address of three words on the line.

/Sbin/ifconfig eth0 down
/Sbin/ifconfig eth0 hw ether mac address
/Sbin/ifconfig eth0 up

The second is to install the linux version of The ruijie client, so that I can also dial the Internet in linux, no need to rely on other people on the campus network, however, this ruijie installation always encounters a problem. Every time it is run out, an error occurs, saying that libpcap is missing in my system. in the so.0.6 file, libpcap is a library. To put it bluntly, it is used to capture packets directly from the NIC. However, we cannot find version 0.6 every time, but only version 0.8 is available. However, ruijie is so hateful that it is determined to be 0.6, and the updated version 0.8 cannot be searched, by default, libpcap has been installed in our system, and its version is later than 0.8. Therefore, we only need to make a soft connection to solve the problem: [root @ localhost lib] # ln-s libpcap. so.0.9.4 libpcap. so.0.6.2. After the soft connection is established, there is no error, but the new problem comes again, that is, this linux version of ruijie is difficult to dial the number.

In other words, I still cannot access the Internet on linux. Over the past year, only half of the problems have been solved.
