Detailed Description

Manage the list of IP addresses that a server might encounter. Block malicious addresses. Override this to provide extra functionality like db persistence. Similar to a load balancer. Multi Thread safe.

detect DoS ping attacks. Cannot detect source since it might be spoofed.
detect TCP connections used to attack passwords.
Todo:
block a range of addresses.

Member Function Documentation

◆ AddLogAddr()

ITERATE_t GrayLib::cNetAddrMgr::AddLogAddr ( cNetAddrTracker * pClientAddr )

inline

manually add an IP from some table ?

◆ CreateAddrTracker()

cNetAddrTrackPtr GrayLib::cNetAddrMgr::CreateAddrTracker ( const cNetAddress & addr )

virtual

Just create a new cNetAddrTracker but don't add. Allow this to be overloaded.

◆ FindAddrTracker()

cNetAddrTrackPtr GrayLib::cNetAddrMgr::FindAddrTracker	(	const cNetAddress &	addr,
		bool	bCreate = `true`
	)

We are being hailed/pinged/connected by some client. Is this a client i know/like/dislike ? Should i block/ignore this incoming client?

Note: sorted by start IP of range.

◆ onTickAddrArray()

void GrayLib::cNetAddrMgr::onTickAddrArray ( )

periodically age the list.

Call this once per minute or so. Age out any IP's that should go away.

◆ RemoveLogAddr()

bool GrayLib::cNetAddrMgr::RemoveLogAddr ( cNetAddrTracker * pClientAddr )

inline

manually remove an IP and let it progress naturally from here.

◆ UNITTEST_FRIEND()

GrayLib::cNetAddrMgr::UNITTEST_FRIEND ( cNetAddrTracker )
