Here the subject does not match the title, only the record about feelings.
Official online propaganda is this:
Yes, that's the basics of computer networks, it is the beginning and wanted to be with TCP / IP as the core of it, and brought Xie Xiren "computer network" read it again, thinking about it now. Facts have proved that a little Naive. (Fortunately did not hold TCP / IP Illustrated Volume watch).
Here's a short list of the basics of computer networks involved, providing little direction for the future of sprouting new reference.
1, TCP / IP related not say, sure to be mastered, including VRRP (Virtual Router Redundancy Protocol, to understand their own), VLAN applications, ARP, NAT, DNS, switcher, switching equipment and a variety of other related technologies.
2, the standard (10Mbps), the value of Fast Ethernet (100), and subnetting, the data frame forwarding features, wide area network lines, DNS tool (nslookup), ping principle, routing status view (netstat, route), tracert, tcpdump use (use the option key), using Wireshark, WiFi wireless access technology in the wired network layer,
3, the relevant network storage, including various types of RAID technology and its characteristics, SAN storage, NAS (Network Attached Storage, network attached storage), IOPS, network file sharing system CIFS, NFS and characteristics
4, Web-related. A variety of server-related technologies, including IIS (different mainframe technology), Tomcat, Apache and other features for the common Web attacks (XSS centralized classification and characteristics), SQL injection, WordPress brute force, Http protocol, mention the right vulnerability, firewall , IPS, IDS, HTTP Headers header rewriting stage, C / S, B / S, P2P features
5, encryption technology. IPSec VPN, (non) asymmetric cryptography, digital signatures, the SSL
6, Linux basic operations. Including service start and stop, / etc / rc.d / action script, network configuration queries (ifconfig instead of ipconfig), system status view (top), KVM and control, other commonly used commands file permissions (rwx: 421)
These are being summarized remember something, hope that we can be fully prepared, at the same time on the same omissions attended a friend Message to add it!
