Howto: Oscam watchdog

**master G** · Mar 7th 2012

Oscam is capable of restarting its self on errors/seqfaults. But I wanted to make sure that Oscam is "REALLY" handling some traffic (doing its job properly).
And here comes the Oscam watchdog into play. The idea of the watchdog is quite simple.
If no successful ECM's are logged within a defined time frame, then the Oscam is started again.

Prerequisits:
- Oscam started with level 1 debugging option. Just look at the init script from the first howto.

Code

-d 1

Installation:
We are going to create two scripts. One is the Oscam watchdog daemon, that will run as a proccess under GNU-Linux.
and a init script for the Oscam watchdog.

Code

touch /opt/oscam/bin/oscam.watchdog.sh
touch /opt/oscam/init/oscamwatchdog
chmod +x /opt/oscam/bin/oscam.watchdog.sh
chmod +x /opt/oscam/init/oscamwatchdog
ln -s /opt/oscam/init/oscamwatchdog /etc/init.d/
update-rc.d oscamwatchdog defaults

Copy the following code into "/opt/oscam/bin/oscam.watchdog.sh"

Bash

#!/bin/bash




# Restart/start oscam if we dont log any successful cw transactions within a defined time frame"

Now you can start stop status the Oscam watchdog by running

Code

service oscamwatchdog start
service oscamwatchdog stop
service oscamwatchdog status

Every time you add a new Oscam instance you have to add it to the variable "OSCAM_SERVERS" in "/opt/oscam/init/oscamwatchdog"
and stop and start the watchdog.
There are also the variables "CHECK_INTERVALL" and "MAX_RETRY" in "/opt/oscam/bin/oscam.watchdog.sh"
With "CHECK_INTERVALL=60" the watchdog will check every 60 sec. This is a reasonable values since it would not stress your system.
Decreasing this value will put more load on your system.
With "MAX_RETRY=4" you tell the wathdog to restart/start Oscam if no ECM's are seen after 4 minutes.
Higher values are better to avoid alot of disconnection/reconnection ... when you are connected to other servers.

Cheers!

Howto: Oscam watchdog v1.2

Howto: Oscam watchdog v1.2
Hi all,

Some have reported, that version v1.1 of Oscam watchdog is not working properly!

Thus i have done some changes to introduce v1.2

There is also a new feature in this version. it will restart Oscam if the ecm time is continously too high ... <= 3000ms.
This happens mostly just before the ECM requests goes permanently into timeout (5000ms).

good morning,

I have problems ( stop of vision) with alone oscam on Vuduo, ( random buy with oscam running in ps), and I would want to know if it is possible to make to turn these scriptses in my decoder.
I think that, because of the busibox reduced of the decoderses E2, will want us quite a lot changes.

I ask therefore if someone has already adapted these scripts for decoders E2.

Thanks

sorry for my "google english"
