) +GRXRThe sender uses the specified g (x) to generate the CRC code word, and the receiver verifies the received CRC by the G (X). 4, CRC check Code software generation method:With the help of polynomial division, the remainder is a check field. For example: The Information field code is: 1011001; the corresponding k=6 polynomial m (x) =x6+x4+x3+1 assumes that the resulting polynomial is: g (x) =x4+x3+1; th

Go O M to check the web service status Continue the previous code. You often need to check the status of web services during O M.

Because Linux installs a lot of software, there is no common way to find out if some software is installed. This is a summary of the following categories:1, RPM package installed, you can see with RPM-QA, if you want to find a package is installed, with Rpm-qa | grep "The name of the software or package".rpm -QA | grep Ruby 2, with the Deb package installed, can be seen with dpkg-l. If you are looking for a specified package, use Dpkg-l | grep "The name of the software or package";dpkg -
