* radius
* ircd (connect, send quit) (same as sysmon check)
* pageinterval per host configurable
* sensitivity per host configurable
* pktloss (ping w/ counts, and tolerance checking)
	* keep history for 24 hours
	* tolerance config for pings lost in a period
	* if total loss, just report as down
	* ex: far-away-site pktloss 15 1 2 "far-site" mail@site
	* will send 15 pings every 1 minute, if more than 2 lost,
	  report loss
* dns checks (native)

        switch(icp->icmp_type) {
        case ICMP_ECHOREPLY:
                (void)printf("Echo Reply\n");
                /* XXX ID + Seq + Data */ 
                break;                  

* bug in config parser w/ lots of config includes (?)
