Fwd: [ PRIVACY Forum ] Critical bug threatens to bite mobile phones and networks
by Jay R. Ashworth 20 Jul '16

20 Jul '16

Heap overflow bug in either a widely used ASN.1 library from Objective Systems, apparently popular with cell-radio industry people. Not sure if this will leak over into NANOG land -- but neither are you, and that's most of my point. DO *you* know if this library is used in your routers? Can you find out? How easily and quickly?

Re: [AFMUG] Mimosa B11 Tx power at varying modulations
by Eric Kuhnke 18 Jul '16

18 Jul '16

I found this as well, which is very helpful. Wish more radio manufacturers were as clear about this in the spec sheet: http://backhaul.help.mimosa.co/backhaul-faq-maximum-tx-power-details In one channel, two chains, it's +24, if using two channels and four chains +21 Tx power. Then it's possible to manually do the link budget and path loss calculations based on that (or plug Tx power dBm + dBi gain for preliminary PTP link calculations into something like Radio Mobile).

akamai abnormal spike
by eric c 18 Jul '16

18 Jul '16

Good afternoon, Has anyone notice any abnormal spike in Akamai trafic in the last 24-48 hours compared to other days. I know it was black tuesday yesterday but traffic from last month didn't even come close to what we saw from Akamai. We have some caching servers and even notice a spike to them as well. Limelight even showed up on our network. thanks eric
