On the main page of the module, click on the Search display mode link. This will take you to a search form as shown in Figure 11.3.

The form shows several different criteria for finding processes, of which you can choose one by selecting the radio button next to it. The criteria are:

Owned by Processes owned by the user whose name you enter next to this option will be found.

Matching Finds processes whose command or arguments contains the text that you enter next to this option.

Using more than Finds processes using more than the specified percentage of CPU time.

Using filesystem Processes whose current directory is on the chosen filesystem or are accessing any file on it will be found. Useful if you cannot unmount a filesystem because it is busy.

Using file Finds processes that have the entered file open for reading or writing. If you enter a directory, any process that has it as its current directory will be found.

Using port Finds processes that are sending, receiving, or listening for network traffic on the entered port using the chosen protocol. Useful if you know the port number a server is listening on, and want to find the server process.

To filter the Webmin search processes from the results, select the Ignore search processes in result option. This can be useful when searching by CPU usage, as the Webmin processes use up a lot of CPU time.

After you have selected the search criteria, click the Search button. Any matching processes will be displayed below the form.

If you want to see additional information about a process, change its priority, or send it alone a signal, click on its Process ID in the results.

To kill all matching processes, click the Terminate Processes or Kill Processes button. You can also send any signal to all processes by selecting it from the list next to the Send Signal button. A page will be displayed listing each process ID and whether it was signaled or killed successfully.
