Apt Local source build (can be used for LAN Apt-get source or local source) This document describes the use of Apt-mirror software to build apt local source requirements: Intranet development environment for its specific reasons can not Sisu network, So we need the local intranet source to make it easy for developers to download and install software recommendations: Use a single disk to store source files o

Because the company in the computer room hosting server IP is not enough, but also for security considerations, so that a number of virtual nodes can not directly access the Internet, so I xenserver physical nodes through the use of iptables NAT function made a simple implementation [Root@xenserver-cukxsegi ~]# sysctl net.ipv4.ip_forward=1 #开启转发[Root@xenserver-cukxsegi ~]# Echo ' net.ipv4.ip_forward=1 ' >>/etc/sysctl.conf #让重启不失效[Root@xenserver-cukxsegi ~]# iptables-p FORWARD DROP #将FORWARD链的策略

Intranet address port is the LAN MSSQL address port, the network address port customization.(2) After the mapping succeeds, the external network access connection MSSQL uses the mapped extranet address domain name port.

A simple introduction of squid Through Squid Proxy server to achieve intranet users to share the Internet, configure Squid cache and basic access control to accelerate and restrict access to Web services. For web users, squid is a high-performance proxy caching server that speeds up the intranet browsing the Internet and increases the client's access hit rate. Squid not only supports HTTP protocol, but al

Objective:Sometimes we want to access the local area network SQL Server server, such as test environment database in the company intranet, back home or at the customer site to connect to the database in the intranetThe first step: if you can connect to the local area network database 192.168.150.129, remote also can connect itThe second step: Add a TCP port in the intranet pangolin, the IP of the local IP,

Intranet SecurityThe problem has been hard to solve since the beginning. The most important cause is that LAN technology has been adopting an open and shared resource model since the first day of commercial use. While pursuing high convenience, security will inevitably be affected. According to various published survey data, even in the most optimistic circumstances, the loss caused by Intranet security pro

Intranet SecurityFor enterprises, the problem should start from four levels and take into account the internal network security of the enterprise comprehensively. In terms of it o M, the security of user behavior should be determined. Finally, when users pass layer-by-layer security checks, in addition, enterprises also need to check the security of their infrastructure configurations to ensure boarding security. In response to the above problems, ac

Today, under the Linux server encountered a strange problem: The network domain name ping results and nslookup results inconsistent, the resolution process is recorded as follows. Confirm that the/etc/resolv.conf configuration is correct: no problem; Confirm if additional domain name is added in/etc/hosts: no problem; Confirm the correct IP address in the domain name server, and colleagues confirm that the intranet domain name has bee

On a Linux server or on a Windows server, You can use this command to create a Web service that can be accessed quickly in the intranet, as long as you install Python. In the directory where you want to build the Web service, use the python3.x built-in method:Python-m Http.server 80008000 is the port number of the link, so that the local in the browser can access the directory through http://localhost:8000, and the LAN, such as other computers, can b

Problem Description: 1, the PIX placed in a fixed IP environment (external network for fixed IP), and set the correct ACL allow ICMP release, this case intranet can be normal Internet access can also ping the extranet. 2, and then put the PIX in the ADSL environment (with PIX to dial), ACL or before the same, PIX under the intranet computer can only surf the internet, can not ping the extranet. Solution:

One, the internal LAN all use the private address on the network, under the normal circumstances, the internal computer in the direct use route external access, will because the computer uses is the Internet reservation address, but is filtered by the router, thus causes cannot access the Internet resources, The solution to this problem is to use the NAT address translation function provided by the routing operating system to convert the private address of I
