1. CMG EAM Platinum Firmware The Enable box should normally be checked but can be left unchecked if you only want to use the associated PPP connection occasionally An existing watchdog service can be stopped and its configuration deleted by selected the Delete check box and then clicking the Submit button If the PPP connection relies on a modem link for its transport there may be a significant delay between instructing the PPP link to start and the connection being established So that the watchdog does not falsely detect a failed link during this period it can be instructed to sit idle for a number of seconds before it begins to test the link The length of the required delay should be entered into the Daemon startup delay field Once the start up delay time has elapsed the watchdog periodically tests the connection To ensure that there is a valid end to end connection where for example a multi hop link is in use the exact method of testing is user configurable The most common method used is to use the ping command to verify ICMP connectivity to the ultimate remote host but you are free to use the command or script of your choice here so long as it returns a non zero exit status on link failure When using ping you should always use the c count option or the command will never return The contents of the Time between tests field determines how often the configured test is applied It can be set high
