1. Create tunnel on the server using SSHSSH 10080 -f-c-q-n [email protected]112.34. 113.35 -D: Let SSH on the specified port (1025-65536-----n:tells SSH That no command would be sent once the tunnel is up# the last specified is the SSH user and the currently established tunnel server IPRun in the background after execution, you can view the process through PS2.

I. Achieving In Linux, the implementation of the tunnel is based primarily on two files new_tunnel.c and ipip.cAt the same time Linux defines a new protocol type--IPIP (IPPROTO_IPIP), similar to the package type described above.Basic ideasThe implementation of IP tunnel in Linux is also divided into two parts: packaging parts and sealing parts, respectively, division of the post and receive. But these two p

Use putty's SSH tunnel to connect to Oracle1. Set SSH tunnel on putty of localhost, for example:In this way, the port 1511 connecting to the local machine will be forwarded to port 1521 of remoteIP. Click "Add", and then log on to the remoteIP through SSH. The SSHtunnel is created. On the local machine netstat-a | find "1511", you can see that port 1511 has a linstener listener.TCP 127.0.0.1: 1511 CNHSHAKER

HTTP tunnel principle and firewall penetration method-2 This article provides a way to establish a TCP connection through the proxy server to bypass the firewall.Generally, the firewall limits connections on many ports, but HTTP connections are still allowed (otherwise, no one can access the network ). The Protocol specifies a CONNECT request method. The client can use this method to notify the proxy server to connect to the specified server IP addres

0. PrefaceNC is a good tool for both ends of the network connection, but also a temporary port forwarding. (What is the permanent port forwarding?) With Iptables)SSH is also a good tool in this area, the advantage is that encryption is reliable reusable at one end of the operation, at the cost of having a login account.We know that SSH automatically encrypts and decrypts all network data between the SSH client and the server. However, SSH also provides a very useful feature, which is port forwar

HTTP communication, in addition to the client and the server, there are some applications for communication data forwarding, such as proxies, gateways, tunnels. Work with the server. Agent Forwarding function, there can be multiple proxies between the client and the server.

But if the data is eventually queried by the public, there will always be a channel to access the database. The following uses Navicat and SECURECRT to achieve database access to two different scenarios.Scenario One: The dat
