Re: DoS attack? / CCR1036 / garbage floods from customers (18Mbps at the moment)

yes, thank you, I know I could use this feature, but a) it is hard to implement in this case, because (during the day) the "wrong" traffic is maybe 10% of the "correct" traffic, so which connection limit should we set, before damaging our normal users? b) it would not answer our question, which IP a...

DoS attack? / CCR1036 / garbage floods from customers (18Mbps at the moment)

Hello, I would like to share something we have been experiencing recently on our network; we are a small WISP; in one of our networks we are currently doing traffic shaping only centrally in our core (server room), and not at cpe level; usually it works fine but since a couple of days we are noticin...

Re: RB953GS-5HnT

RP-SMA was created some 20 yrs ago due to regulatory / law requirements... it was meant to be HARDER for the end user to connect to a wifi device another (higher gain) antenna than what came bundled from the factory now it does not make any sense, RP-SMA cables and pigtails are everywhere (and, yes,...

Re: Newsletter 60: 802.11ac / 953GS-5HnT ?

does the 953GS-5HnT have galvanic isolation? can it function with both positive and negative voltages?

953GS-5HnT temperature range?

which is the allowed operating temp. range?
0 ... 50 (C degrees) ?
-20 ... 70 ?
-40 ... 85 ?

I got today my first sample... really heavy piece, I assume due to the large 3x3 radio heatsink

Thanks

Re: CLOUD CORE ROUTER

Hello all we changed hardware; we are now using the CCR1016-12S-1S+ as BGP router (still w/ 6.13) two 300Mbps peers; acting only as border gateway (we have a separate CCR for NAT and a 3rd one for bw shaping) until now, no issue with bgp, finally uptime 10d and counting, let's hope we'll see 30d too...

Re: CLOUD CORE ROUTER

Two CCR in production, both RC11

one with no problems, uptime 28d and counting

one with "freezing" problem, it happens randomly, first every 10 days, then after some hours (since last reboot), then after 3d

we'll going to test RC12 when released
