In Internet-based applications, programs often need to send e-mails automatically. For example, a website registration system will send an email to confirm the registration when the user registers, and when the user forgets the login password, the password is retrieved by mail. The Smtplib module is a client implementation of the SMTP (Simple Mail Transfer Protocol) in Python. We can use the Smtplib module to easily send emails. The following example uses less than 10 lines of code to send an e-

Because of the need to use Wireshark for the remote grab package, you need to install the corresponding RPCAPD service on the remote host. As long as the WinPcap software is installed on Windows, it already contains the RPCAPD service, just start. But Linux needs to compile on its own.Note: Wireshark supports remote Packet Capture protocol protocol, as long as the corresponding RPCAPD service routines are installed on the remote host.The installation commands are as follows:

This is article describes a design and implementation (C #) of the Remoting over Internet using the Web Service as a gateway I Nto the Remoting infrastructure. The Web Service Gateway (Custom Remoting Channel) allows to enhance the Remoting Channel over Internet and its chaining WI Th another heterogeneous channel. Consuming a remote object over Internet are full transparently and it doesn ' t require any special implementation from the R

We create a table in the database named: Tsys_primarykey, which includes three fields, as follows: Tsys_primarykey keyID BIGINT TableName VARCHAR () PRIMARYKEY VARCHAR where TableName saves the table name, PRIMARYKEY saves the name of the primary key, keyID the value of the primary key, so that the value of the primary key is taken
