Re: Decommissioning of the Brandmeister 3101 Server

Post by K2IE »

The best way for folks in the USA to select a master is to ping the three available (3102, 3103 & 3104) and to choose the one with the fastest response time (the smallest number).

For example, here is my ping of 3104:

$ ping -c 5 3104.repeater.net
PING 3104.repeater.net (162.248.88.117) 56(84) bytes of data.
64 bytes from 3104.repeater.net (162.248.88.117): icmp_seq=1 ttl=59 time=17.5 ms
64 bytes from 3104.repeater.net (162.248.88.117): icmp_seq=2 ttl=59 time=18.4 ms
64 bytes from 3104.repeater.net (162.248.88.117): icmp_seq=3 ttl=59 time=17.6 ms
64 bytes from 3104.repeater.net (162.248.88.117): icmp_seq=4 ttl=59 time=18.5 ms
64 bytes from 3104.repeater.net (162.248.88.117): icmp_seq=5 ttl=59 time=17.9 ms

--- 3104.repeater.net ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 8ms
rtt min/avg/max/mdev = 17.545/17.999/18.486/0.383 ms

With an average response time of just under 18 ms, this is the best choice for me.

The hosts can be pinged via 3102.repeater.net, 3103.repeater.net, and 3104.repeater.net respectively.

Going with the lowest ping time is good advice, until it isn't.

My lowest ping time, by far, is to the 3103 master, but on that master I was seeing 30% loss!
Changing to the 3102 master fixed the issue with loss, which is now at 0%.
I am in western Washington.
Interestingly, while my pings to 3102 are consistently 20 ms higher than with 3103, the variability in the ping times is WAY lower with 3102, only a few milliseconds.

I’m new to how to ping a server. How can I ping the suggested Brandmeister 3102, 3103, 3104? Direct me to FAQ or help pages is appreciated.

Try this:

Code: Select all

ping -4 -c 4 3102.master.brandmeister.network
ping -4 -c 4 3103.master.brandmeister.network
ping -4 -c 4 3104.master.brandmeister.network
The "-4" option specifies IPv4, the "-c 4" limits the number of pings.

Sample:

Code: Select all

$: ping -4 -c 4 3102.master.brandmeister.network
PING 3102.master.brandmeister.network (74.91.114.19) 56(84) bytes of data.
