Using DEDECMS to customize a Send mail php file, using the dedecms comes with mail.class.php, can be sent locally, after uploading to the server, prompted cannot connenct to relay host Smtp.qq.com Error: () error:cannot send email to [email protected] online to find a lot of articles, finally solved, the problem is in the server environment configuration. Find php.ini, see two places, one is Allow_url_fopen, this place is to be set to on, and the othe

One: DHCP 1. Insert the system disk first and mount it into the server Find-name "dhcp*" Query and locate the package to install 2. Overwrite the configuration DHCP template file on the/etc/dhcpd.conf and then configure the address pool, such as the following figure 3. Configure the DHCP network adapter to set IP as 192.168.1.2 default gateway 192.168.1.1 (relay IP address) and then restart the network card service-then start DHCPD service

For DHCP Relay configuration content, we can analyze and learn through the following networking instance. First, we need to understand the network structure and then describe the configuration. Functional requirements and networking description DHCP relay Configuration "Configure Environment Parameters 』 1. the IP address of the DHCP Server is 192.168.0.10/24. 2. the DHCP Server is connected to port G1/1 o

The structure of the DHCP protocol is a complex part of knowledge. Here we will look at the relevant content in detail. Describes the fields of the DHCP protocol and related knowledge of DHCP Relay. Hope to help you. DHCP fields: When the op field indicates whether the current message is a Client request or when the server responds to 1, it indicates that the Client request is 2 and the server responds. The htype hlen field indicates the network hard

The core switch is still quite common. So I studied how to use the DHCP relay of the core switch to increase security performance. I would like to share it with you here and hope it will be useful to you. In a LAN environment, network virus attacks are always inevitable. Once a workstation is accidentally infected with a network virus, it cannot access the Internet normally. In addition, if you change the IP address at will, IP address conflicts may e

According to the reporter's understanding, at present, the only professional Mesh-Wifi equipment manufacturer in China -- Shanghai huichuang communication (GBCOM), in its MESH network, uses the multi-hop feature, A non-conventional seamless coverage technology-MESH terminal relay was developed. Multi-hop refers to the use of a terminal as a

We have introduced the specific content of the wireless relay mode. I believe everyone knows about it. How can we use the AP and wireless relay in the networking, to achieve the perfect networking effect? Let's take a look at the following to see how different wireless networks are built by different numbers of wireless products. We need to consider the important factor of wireless

The online world is like a huge garden. Any technology is booming. Therefore, we need to pay attention to the basic network relay settings. Here we will introduce them in detail. Of course, not all wireless devices can achieve the purpose of Wireless Network Relay Settings and amplification function, which requires the combination of powerful firmware program, the routing device used by the author has refre
