Does HTTP have to be performed on TCP?Does SSL have to be performed on TCP?...In fact, HTTP does not stipulate that it must be executed on TCP, or even FTP is not necessarily executed on TCP! HTTP or FTP is simply that the underlying channel to ensure that the data in the sequential transmission and reliable arrival, because the transport layer in addition to TCP no other well-known protocol to meet this demand, so most of the applications have chosen TCP, but you know, this is not mandatory.SSL

VPN (Virtual Private Network) is an extension of a Private Network. It can simulate a point-to-point Private connection through a shared Internet or public Network connection, send data between a local computer and a remote computer. It has good confidentiality and is not subject to authorization, so that both parties can establish a free and secure point-to-point connection.There are two common VPN services in Linux: pptp and openvpn. The former is s
There are many methods for setting up a vpn Server on ubuntu with a single Nic, including PPTP, L2TP/IPSec, and OpenVPN. Among the three methods, the latter two have better security, but the configuration is troublesome. OpenVPN also requires additional clients on the Windows/Mac platform. Although the L2TP/IPSec method is better, after I configure it, although Windows and Linux users have no problems, Mac/
, and PCs are no longer popular, the old idea is encouraging many people to buy or assemble high-end PCs, just as many people love almost extinct mainframes 10 years ago. In this post-terminal era, it may be a good idea to buy a small Board containing Linux. It consumes less power, has no noise, is small, and can be used wherever it is needed, it doesn't matter if you start the system for a long time. It is the best choice for a home Internet proxy. My colleague bought a small board like this, w

Use the Chkconfig command to view services (or programs) that start automatically at different startup levels, with the following command format:
Chkconfig--list
The output may be as follows:
OpenVPN 0: Close 1: Open ... 6: Close (0-6 is the start level; Turn off/Open the automatic start option for the service at the appropriate level)
If you want to make changes to the Auto start option, the command format is:
Chkconfig--level x Name On/off

Openvpn implements Security Based on OpenSSL, but it is not an sslvpn in the traditional sense. It is just a common VPN that works on the IP layer rather than the transport layer. VPN has two meanings: V, virtual, P, and private. Virtualization means that physical cabling is not required, and only one network is implemented logically. The reason why a virtual network can be implemented and established depends on the advantages of a layered model, the
