Re: Inferring the location points of traffic exchange between two networks

Unless you have a tremendous amount of peers and feeds to work with,
you'll have a hard time building a valid interconnection graph from BGP
cli outputs.

The best mapping outputs I have seen for now have been built using probe
clusters (either RIPE ATLAS or NLNOG Ring) with traceroutes, by merging
data from the observed routes AND both DNS and BGP.

DNS is quite usefull here as most of us use location codes in router's
FQDN. BGP will only help in matching subnets within ASes and corroborate
some discrete relationships.

Also note that each node in the directed graph may expose multiple
addresses, and that latency between routers isn't a reliable metric
(still a usefull indicator, YMMV)

Re: SMS gateways

[Adam Kennedy]

The device can definitely send texts. I had to purchase the device as a
data only device, then I contacted support and told them I was working with
Cisco on a project where the router uses these devices but needs text
capability. They did some magic on the number in their system and got it up
and running.

network issue on ec2 classic us-east-1??

[Grant Ridder]

Hi,

Over the last 6 hrs i have had over 100 instances in us-east-1 in EC2
Classic fail their instance health checks and a reboot via the console
solves them.  Logs on the host point to a loss of all network
connectivity.  Anyone else experiencing something like this?

Reached out to AWS support and haven't gotten anywhere with that yet.

Grant,

We have been having issues for a few weeks now with instances that randomly 
stop getting their IP from DHCP. Did you see any dhcp errors?

Dovid

Neil / Dovid,

How long ago did your issues start?  Symptoms are the same, but the issue
for me started early this morning at an alarming rate.

Gotcha, thanks for the info.
I am at 128 instances and counting in the last 8 hrs

Re: network issue on ec2 classic us-east-1??

[Grant Ridder]

Thanks to all the replied on and off list!

tl;dr dhclient died and the instances gave up their IP's

Turns out this one was inadvertently my fault.  I got bit by a bug in an
old version of NetworkManager.  Something triggered an update of a package
on some of my instances, which lead to this bug showing up.

The bug appears in versions of NetworkManage prior to
NetworkManager-1.0.0-14.git2015012
https://bugzilla.redhat.com/show_bug.cgi?id=1285974
https://bugzilla.redhat.com/show_bug.cgi?id=1136836

Thanks!
Grant
