Test the OpenVPN encrypted tunnel on a single machine and solve the problemIn fact, the relationship between this article and OpenVPN is not very large, but the problems exposed during the OpenVPN test. This article contains many details about IP routing and conntrack.If you ping the IP address configured on a network card, the result will not pass through the ne
Two days ago, hivefans built an openvpn server on a server in the cluster because of the inconvenience caused by the cluster's network segment. If you have encountered some problems, record them.
He only built an openvpn and did not install ovpn on other servers in the cluster. He wanted to route the Intranet network segment of the cluster through ovpn, the company can access the Intranet address of the cl
It would be nice if openvpn can also achieve the transmission mode VPN. If the VPN product based on openvpn can be connected to the user's network environment as an expensive network cable, it would be nice to automatically capture the traffic of interest; how nice is it to configure only one IP address to work without configuring any route.
We know that openvpn
Three virtual machines are installed on a 2G memory desktop and run well, that is, swap is used more often. See the previous article. Now the platform is basically ready, with its own laptop as the general control, and four machines running on the lab desktop (one solid and three virtual machines), coupled with one server, can do a lot of things, because KVM is a bridge network, the three virtual networks are consistent with the real-world status. They all contain their own IPv4 and
1. First verify that your DNS server supports IPV6, which generally refers to routes in the network.2. If there is no route in the network, add the IPV6 address and name of the other party directly in the hosts file.3. Using a UNC path, change the colon to a hyphen and attach the. Ipv6-literal.net to replace the symbol% with S. Example: \\2001-db8--85b-3c51-f5ff-

In the past, everyone was using IPv4, that is, the address looks like a 114.255.40.66. However, such an address is not enough, there is a similar IP address such as 2001:DA8:215:4009:250:56FF:FE97:40C7.
At present, a network card will use both addresses at the same time,

I. openvpn needs to be installed in RedHatLinux enterprise 4. Easy to install, high platform compatibility, and no need to compile the kernel. (I'm disgusted with re-compiling the kernel software); 2. I can penetrate the NAT Intranet without limits. (This is critical because my server is currently in school, in our lab, we use NAT layer by layer.) due to the above two restrictions, I have tried pptpd and opensvn in many existing solutions. Pptpd is an

There are several timers in openvpn. These timers limit the maximum duration of some specific behaviors of openvpn. If they are not set properly, they may cause inexplicable disconnection problems, however, how to set these counters does not have a general solution. In certain cases, they cannot be too large or too small.

that, many of the above-mentioned communications are still fully automated. This is reflected in several ND packets, such as router requests/announcements, and adjacent contact requests/announcements. Those who have played OpenVPN should be familiar with all of this.

With the continuous development of personal computers, mobile terminals and even the internet of things, there is a great demand for IP addresses. As the IPV4 protocol was designed without expecting that the network would be so developed in the future, the number of IP in the IPV4 network seemed to be stretched relative to today's demand. Add IPV4 Address resource allocation is uneven, resulting in some countries IP address resources are very tense, will suppress the deve
Depending on the deployment speed of the existing IPV4 address, the remaining address will be exhausted in 10-20 years. Therefore, the network gradually from IPV4 to IPv6 conversion is inevitable, the corresponding various network applications will support IPV6. For Java, starting from its 1.4 version of the IPV6 to provide better support, the programmer has basi
