I think OCMINER is a very experienced admin, but I don`t understand, why not up some services that I wrote before?!

They're all in place but they don't work for some certain type of attacks

then may be use limits for connection`s from 1 ip? as I see, for 1 rig it`s 1 connect from ip. so, 10 rigs via 1 ip can have 10 connections.
or I not correct?
may be need some tune for os kernel, like more buffer for tcp, some more virt.mem (like swap part on hdd). if detects many connections from 1 ip (1000 or more), then block it for some time or forever...
I don`t think for new version of wallet, because no one developed it...
Sorry for my broken language Cry

Yes, I limit connection per IP; i have some geofencing and plausibility checking in place but there are certain type of attacks that are not so easy to mitigate.

The best solution - at the end - would be multiple pools, as the attacker won't be able to dos them all

what`s port`s has been attacked last times?
for many pool we need new wallet version.

The stratum is under attack at layer 7 - I actively have to monitor and ban/fix things - that's what taking the time.

Yes pool.mn has contacted me but they can't get the wallet compiled because of some boost stuff as far as I know

I couldn't mining in the CC pool recently because the pool was DOS?I have to change to SOLO, but with luck, I hope OCMINER can keep the pool well and mining better.

I also encountered this problem, not normal mining, low yield, I believe ocminer will have a solution, DOS attack is hateful.

And in 5 minutes it go to down again? Make these process automated. ru ip`s or china ip`s, does not matter if servers without security.

His last IP was from the netherlands.. Leaseweb

Pool is fixed again, yes, a lof of russian IP's are banned.

I'd recommend fixing the wallet so other pools can open and the DOS'ing will be pointless then.

Yeah, not connect to the pool. but, I`m from Russia. I`m banned? Huh

If some ddos the pool, may be need to up some services like logcheck, Portsentry and fail2ban?

Pool should be ok again... at least for a while

do not work - stratum connection failed every minute

try again.. some russian guy is ddosing the pool as soon as I restart it

Ociminer long ago we hope you fix the pool, now we can mine in suprnova xcn?

The pool is ok currently and I'm also in contact with other pools but the problem is the other pools cannot get the (new) wallet compiled and synched, it crashes during sync and causes lots of trouble..

Again the pool has connection problems, I only work about two hours
