Iptables implementation of Port forwarding, port mapping and two-way access is not difficult to configure, see below: Allow packet forwarding: #echo 1 >/proc/sys/net/ipv4/ip_forward Forwarding TCP 8081 to xx.xx.xx.xx: #iptables-T nat-i prerouting-p tcp–dport 80-j dnat–to

Configure port forwarding in Centos to forward port 80 requests to port 8080 Apache is deployed in Linux. To ensure security, we use a non-root user to start the service. However, when binding a domain name, we cannot directly access port 80. As we all know, in unix, non-ro

Article Title: Use ssh port forwarding for mail forwarding. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. A wiki is set up on the server. you need to submit an email report to the users on each watch's interface based on the

　　Described in the previous article, You can add a record in the local hosts file to resolve the local 127.0.0.1 of the trusted domain name in the public number, but Tomcat does not start on the non-root 80 port of the Mac, so we can use Pfctl port forwarding to forward the request on the local 80 port to

Port ing/port forwarding in CentOS = [Implementation goal] ============================== [Server A] has two NICs, one connected to the Intranet and one connected to the Internet. [server B] only has one Intranet Nic; Access Port 7890 of [server A] and jump to port 80 of [se

1. Allow packet forwarding: #echo 1 >/proc/sys/net/ipv4/ip_forward 2. Forward TCP 8081 to xx.xx.xx.xx: #iptables-T nat-i prerouting-p TCP-–dport 8081-j dnat–-to xx.xx.xx.xx 3. Enable the forward packet to implement a "bidirectional path" to set a correct return channel for the packet: #iptables-T nat-i postrouting-p TCP-–dport 8081-j Masquerade 4. Means to save the rule to the/etc/sysconfig/iptables file #service iptables Save 5. Restart Iptables to m

Yesterday, I saw two articles about ssh: remote logon, remote operations, and port forwarding. Although I have been using ssh, I only need to use it to remotely log on to Linux. After reading these two articles, I realized that there was such a fun place in ssh, and I was ignorant. So I found some ssh information on the Internet for a rough study. now Yesterday, I saw two articles about ssh: remote logon, r

SSH port forwarding details and InstancesI. Introduction to SSH port forwarding SSH automatically encrypts and decrypts network data between all SSH clients and the server. However, SSH can also forward network data from other TCP ports through SSH links, and automatically provides the corresponding encryption and decr

How to Do SSH tunneling (port forwarding) In this post we will see how SSH works ?, What is SSH tunneling? What is important of SSH tunnels and how to setup the SSH tunnel.When SSH server is installed in machine then by default its allowed SSH tunneling.

MAC OS is essentially a UNIX system, and UNIX systems are mostly non-root users that are not able to use a common port less than 1024 by default. At this time if you need to use 80 ports in your development, such as Tomcat, for example, Vitualbox An HTTP service has been built and you need to do some system port forwarding if you want to access it directly from t
