![]() If you prefer, you can compile and install each of them manually, which is what I'm going to do here. Diagnosis is the first step towards cure! Speed圜GI FPing If you're using Debian, Ubuntu, or Red Hat then you can install these via apt-get or yum. I only had one question.īy recording TTL and packet loss statistics for multiple network links, it allows administrators to go back and see when an issue started to show itself, whether or not it's specific to one site or region and it also helps to show any patterns which may be developing. It was a snap to install smokeping on my windows box and get things up and running. SmokePing is a simple Web-based package that produces easy to read graphical representations of network latency and link quality. In situations in which network response becomes erratic, being able to view a historical chart of TTL and packet loss statistics can be a great aid in understanding how changes in routing paths outside of your networks have affected your WAN links and, therefore, the services that run across them. This is obviously something that can't be avoided, but with a simple and straightforward platform to display statistics on your interoffice connectivity, it's much easier to get a high-level view of network status. Hong Kong experienced intermittent losses of connectivity for the same reasons. This bizarrely threw our Korean office into a total Internet blackout (and Korea is quite a way from Taiwan), which later proved to be due to packet loss caused by the rerouting of traffic in an attempt to work around the broken channels. At the beginning of this year, I ran into problems when an earthquake in Taiwan disturbed undersea transport cables. This becomes even more important when those sites are distributed globally - as the potential for disruption due to unforeseen circumstances is greatly increased. If you are supporting multiple networks on geographically dispersed sites, then it's pretty much essential to have some type of quick reference in place to display the basic status of network connectivity between each one. ![]()
