killppp

Killppp is a helpful software designed to terminate ppp pid after a certain period of time with no traffic. This feature proves to be particularly beneficial for dial-up users who pay for every minute of being online. One of the most common ways of using killppp is to initiate a download and activate killppp to close ppp once the downloading is completed. This way, the expenditure of network connectivity that is not being used will be eliminated.

However, depending on the configuration of your Linux system, you may need root access to terminate a ppp process, and it may have to be the ppp daemon (pppd). To identify the pid of your ppp process, type "ps aux | grep ppp."

So, how does this software work? After activation, killppp monitors network traffic on the ppp0 device every minute. While data is flowing, killppp remains idle. However, if no traffic appears, killppp keeps track of time until the specified period and terminates the ppp process.

Killppp uses the following command line syntax: killppp [-hl] < pid > < n >s|m|h|d. The options provided are as follows:

- < pid >, process ID
- < n >s|m|h|d, n seconds|minutes|hours|days of no traffic
- -h, usage and options (this help)
- -m, manual
- -l, see this script

In summary, killppp is an efficient software that helps you eliminate unnecessary network connectivity costs by terminating ppp pid after a specific duration of no traffic.
