Mail system "Probe".

RouterOS The Dude

Just an idea…

I need a way to keep an eye on mail flow thru multiple layers of a mail system..

I can use dude to moniter the SNMP (port 25 ping), but need to need to verify mail will “flow”..

So…

I was thinking… Oh NO he is thinking again !!! :open_mouth: :open_mouth:

Have two Dudes (1 local and one remote) that talk to each other… IE linked as master / probe / slave..

1st the master sends a message (dude protocol) to the slave that it is sending a message thru the SMTP system (with a time stamp)
2nd the master sends a SMTP message thru the mail system (Yes it needs SMTP auth) to the slave (Yes it needs access to a mail server)..
3rd the slave reports back to the master that the message arrived and the time differance from send to recieve.. (YES clocks need to be in sync)
4th Dude processes the information and applys it to the performance of a mail system object..

Then the process is reversed and the slave sends to the master.. and the results are logged to the mail server object..

The Idea is that if mail does not forward within a given time out, that BOTH sides can take action to allert the system administrator(s) via email ( If up), pager etc…

Any feedback ??

OK here goes again !!


Other possable “probes / Monitors”

  1. DNS.. Known entries IE “www.mysite.com” resolve to 10.X.X.X if differnt or no reply then alert of service fail or DNS rercord tampering… (spoof dns etc) also check for versioning.. to see if changes are made..

  2. SQL use ODBC and simple SQL query against static table IE record count, version etc… will SQL server respond to qry.

  3. WEB open a port 80 connection and request a known page IE “it works” from apachee server etc.

There are others…

I REALY need a good way to verify mail flow and me remotely notified !! :smiley:
