RE: [SA-list] Dependencies

[Ahmed Hassan]

Thanks Dirk - My enteries are in the following order;

1 - Host entries

FW_1 Check
FW_1-Dummy Check
FW_2 check
DMZ_host1 check
DMZ_host2 check
DMZ_host3 check
DMZ_host4 check
   
2- Dependencies
DMZ_host1 depends on FW_2 being UP
DMZ_host2 depends on FW_2 being UP
DMZ_host3 depends on FW_2 being UP
DMZ_host4 depends on FW_2 being UP
FW_2 depends on FW_1 being UP

3 - Check DMZ_hosts if FW_2 is down and FW_1 is up
A
DMZ_host1 depends on FW_1 being UP
DMZ_host2 depends on FW_1 being UP
DMZ_host3 depends on FW_1 being UP
DMZ_host4 depends on FW_1 being UP

B
DMZ_hosts1 depends on FW_2 being UP
DMZ_hosts2 depends on FW_2 being UP
DMZ_hosts3 depends on FW_2 being UP
DMZ_hosts4 depends on FW_2 being UP

BUT when I try to enter the dependecies for Section 3A [above] then it reverts to the entries in Section 3B. For example, when I enter;

DMZ_host1 depends on FW_1 being UP

THEN it changes the dependency to;
DMZ_hosts1 depends on FW_2 being UP

As a result, when the status of FW_2 check is DOWN then the statuses of all the DMZ_hosts show as UNAVAILABLE.

You select the entry you want to duplicate and press CTRL-D, this will open the ADD/EDIT host screen, with a duplicate of the entry you originaly selected.  Click OK and you have 2 entries that are exactly the same.  (Maybe it would be clearer to change the pretty-name of one of them to make sure you understand later why you made 2 identical entries).

 

 

 

dirk.

Yes I do have a ping test for the FWs too.

How do I create the FW dummy entry?

Yes - I will also like to check DMZ_hosts if FW_2 is down & FW_1 is up. But how do I create the duplicate.

 

Sorry for being a "pain".

 

Thanks

For the additional test you want to have you'll need one FW dummy entry.

 

 

        FW_1    check

        FW_2    check

        DMZ_hosts check

 

   

 

    DMZ_hosts depends on FW_2 being UP

    FW_2 depends on FW_1 being UP

 

BUT if you still want to check DMZ_hosts if FW_2 is down and FW_1 is up THEN you will have to duplicate it to get

 

 

    DMZ_hosts depends on FW_2 being UP

    FW_2 depends on FW_1 being UP

 

 

    DMZ_hosts depends on FW_1 being UP

    DMZ_hosts depends on FW_2 being UP

 

 

And you could get some additional alerts...but not all will be duplicated.

 

 

dirk.

I have 2 firewalls and was wondering how I would be able to make my servers on the DMZ depend on the 2 firewalls being available. Thus the availability of the servers on the DMZ depends on firewalls x and y being up.

I have a situation when both firewalls goes down - I receive alerts informing me of the firewalls being down and also the various servers on the DMZ as well.
