Two, a single network adapter to bind multiple IPsSometimes we need to configure multiple IPs on a NIC, for example, in the example above, we also need to configure IP 192.168.168.2 and 192.168.168.3 for eth0. Then you need to create a new two configuration file under/etc/sysconfig/network-scripts:ifcfg-eth0:0 content is as follows:
device=eth0:0Bootproto=staticipaddr=192.168.168.2netmask=255.255.255.0Onboot=yes

Display 3690 while listening, but only valid on 127.0.0.1, cannot accept external connections.But I've already added the-G parameter to the SSH manual saying this option will bind the port to the external IP so that the other machines can connect, but why is this invalid?Google learns the Answer (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=228064):Original-G is only valid for local forwarding, to make remote forwarding also use external IP, you mu
In response to the CC attack, Ddosdefender software was deployed. However, the software has a bug, when adding a blacklist will not determine whether the IP has been added, resulting in a firewall list has a lot of duplicate IP address, you can use the following command to delete duplicate data, only one.Iptables-vnl|grep DROP |awk ' {print $8} ' |Grep-v "0.0.0.0" |awk '/[0-9]/' |Sort | Uniq-c|sort-nr |awk ' {if ($ >1) print $ "" $ |awk ' {for (i=1;iThis article from "Leboit" blog, declined repr

In addition, if we want to get more accurate use of third parties is a good way.
