Route table changing application Jothi 05-13-2005

Hi All,
In my security firewall, implemented source to notify any changes in
route table using "NotifyRouteChange". ie., I am monitoring the route
table, if any change in PC. If any body(process/application) changes
routetable, NotifyRouteChange notifying via, Overlapped.hEvent that I
registed earlier. It is working fine.

I would like to know which application is changing the route table
table during my monitor. Is it possible to find the
process/application name who is changing route table?

Give me some idea on this.

Regards,
SRMJothi

Routes are always updated / changed by the OS, unless you implicitly
disabled ICMP redirects in the OS. How extensive is your route table /
routing environment that you need to stare at that?

That's great. Now, would you like to give people a hint what equipment
this might be applicable to? A PC? Some router? How about what
_operating system_ this might be using?

You might start by examining what applications you have running. The
only application that should be changing the routing table is a routing
management application, such as 'routed' or 'gated' in *nix, based on
Internet routing protocols. Do a search in your textbook for such
acronyms as 'BGP', 'EGP, 'RIP' and 'OSPF'.
