Pinging Question
list Kev14380
Hello,
I work for an organization that has about 100 firewalls deployed. We currently use hobbit to ping all the interfaces to see if they are up. Out of about 500 interfaces we are pinging there are about 10 that will show up as being down on the hobbit web pages but when you ping from the hobbit server manually you get a response that they are up. Any ideas as to why they would show up as down on the web pages but you get responses from manual pings. Is there somethign different about the pings used for the webpages?

Kev, you might want to download Ethereal, http://www.ethereal.com/, and monitor the ICMP traffic between the hobbit server and the remote host. You can filter on local and remote IP addresses to detect the differences between the server automated ping, versus, a manual ping from the server. Gary

I had a similar problem with web pages. Reducing the concurrency on the bbtest-net fixed the problem. Thanks, Larry Barber

I had problems with ping tests using BB so I wrote fping.pl, it is on deadcat.net. It pings your hosts, takes note of any that failed, and pings them at the end again. So if it reports a host down it has actually failed 2 pings during one test cycle. If a host fails the first ping but works on the second it is marked yellow. I had some devices randomly not respond to pings. (I was pinging 1000+ devices in <5 mins though. I had issues overloading the TCP stack but that is another story). It shouldn't be too hard to convert to use with hobbit. (Maybe this idea could be included in the hobbit ping util) Craig Cook -- Systems Monitoring Consulting and Support Services http://www.cookitservices.com
