Chapter 4 test and run SQUID 1. Preparations To test whether SQUID is normal, you must first resolve the domain name www.naizhao.com to the IP address 2.2.2.2. As in the previous chapter, if you are a Netcom user and do not need to perform any operations, DNSPod will return the IP address 2.2.2.2 to you. If you are a telecom user or the resolved IP address is not 2.2.2.2, you must modify the hosts table of

: respawn:/usr/local/squid/sbin/squid? Ns Here we use the respawn option. If the process does not have init, the squid will be restarted. If respawn is used, make sure to use the-N option. After editing the inittab file, run the following command to make init re-read its configuration file and start squid: # Init q

Currently, they cannot proxy protocols such as pop and nntp. However, someone has begun modifying squid.For a long time, squid will be able to proxy these protocols. Can Squid cache any data? No. Like cached cre

If the setting is not written to the Environment configuration file (. profile,. bash_rc), the environment settings will be lost after the logon process is disabled.For example, you use pietty to open two windows, use the same account password, log on to the same server at the same time, and then use the export command in one of the login processes, it will only take effect in this login process and will

After we understand, let's talk about the Ulimit order. Ulimit is used to set s

of which are Web proxies. A proxy server can process complex communication transactions between the client and the server. In addition, it provides anonymous information on the Network (LCTT: indicates that the IP address and browser information of the browser are hidden), which means that your identity and browsing traces are safe. The proxy can configure which websites customers can see and which websites are blocked.2. What is Squid? A:

Squid is a very popular server software under a UNIX-like system, and its most important function is to establish a cache between the client and the service. So squid can be used as a reverse proxy, deploy multilevel caches or build CDNs, whatever the name is, essentially the same. Currently there is also a ported version of
