hide ip linux ubuntu

If you are Linux command-line users, sometimes you may not want certain commands to be recorded in your command-line history. There may be many reasons, for example, you have a position in a company where you have some privileges that you do not want to be abused by others. Or some particularly important commands that you do not want to be executed incorrectly when you browse through the history list. However, is there a way to control which commands

During this time, the hadoop cluster environment was deployed to linux, which involved some linux configurations and was recorded for later use. Linux IP addresses are divided into two types: DHCP Dynamic Allocation and Static address allocation. In the past, dynamic allocation was used. However,

Recently, we need to use the Linux iptablesNAT function to map ports, but the interface machine only has one Nic. To achieve both Intranet access and Internet access, we need to use the methods described below: 1. Assume that the Intranet IP address is address192.168.100.6netmask?255.255.0gateway192. We recently used the Linux iptables NAT Function to map ports,

In many cases, we need to modify the IP address, DNS, and other content. If it is a dynamic modification, We need to reset it after the computer is started, which is very troublesome, A lot of online information can not really achieve permanent modification, or even wrong, here will be the correct settings of the Content shared to everyone to learn, if there is reprint please note the Source: Unknown blog http://qinjiana0786.cublog.cn, my personal boo

Firewalls can be divided into several different security levels. In Linux, because there are many different firewall software options, the security can be low and high, and the most complex software can provide almost no penetration protection capabilities. However, the Linux core itself has a simple mechanism called "Disguise". Apart from the most specialized hacker attacks, it can withstand the vast major
