Yet another day with 8% packet loss from Comcast, it seems. In a fit of frustration, I spent half an hour and wrote a tool that can be used to ping multiple hosts at the same time, for the purpose of making sure that the problem isn't external to Comcast's network.
Here's how to install it:
git clone email@example.com:dmuth/unix-utils.git
Here's how to use it:
./multiping google.com xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net
xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net is a router on Comcast's network which is upstream of myself and one of my neighbors, whom is experiencing the same issue.
And here's what the output looks like:
google.com: icmp_seq=33 ttl=55 time=16.950 ms xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: icmp_seq=33 ttl=61 time=14.612 ms xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: icmp_seq=34 ttl=61 time=14.525 ms google.com: Request timeout for icmp_seq 34 google.com: icmp_seq=35 ttl=55 time=17.031 ms xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: icmp_seq=35 ttl=61 time=13.550 ms google.com: icmp_seq=36 ttl=55 time=14.822 ms xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: icmp_seq=36 ttl=61 time=13.404 ms google.com: icmp_seq=37 ttl=55 time=15.275 ms xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: icmp_seq=37 ttl=61 time=12.806 ms ^C xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: --- xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net ping statistics --- xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: 62 packets transmitted, 61 packets received, 1.6% packet loss xe-3-1-3-0-ar03.newcastle.de.panjde.comcast.net: round-trip min/avg/max/stddev = 9.643/25.537/67.840/13.208 ms google.com: google.com: --- google.com ping statistics --- google.com: 62 packets transmitted, 61 packets received, 1.6% packet loss google.com: round-trip min/avg/max/stddev = 14.782/27.874/65.475/10.500 ms
Only 1.6% packet loss? That's actually one of the better pings this evening. But at least now I have something I can send off to ComcastCares. (And for you nerds out there, yes I checked my modem's status page and made sure it wasn't reporting any errors on the physical cable.)
I hope folks find the utility useful--please like/favorite/+1 this post if you. And if there are any questions, feel free to leave a comment below!
