Re: CPU Usage abuse solution needed

Thanks John Connor, that's clearer, and a lot of valuable information not only for me but for anyone else having similar problems. (BTW I'm not on a subdomain or addon domain, my wp installation is simply in a folder within public_html. My forum is also in a folder, called "forum"). I'll p...

Re: CPU Usage abuse solution needed

Okay, so my site is being throttled AGAIN because, according to the CEO of HawkHost, I spiked CPU for a full minute from 3:25 to 3:26PM today. The site is now slow as treacle, taking up to 15 seconds to load a page (it is normally very quick to load). Here's the graph showing the spike at ~3:24pm (t...

I was going to block Singapore as there is a new bad bot from there but one of my forums has a couple of users from there
I don't fully block, I just give a JS Challenge. Real users can get through

Re: CPU Usage abuse solution needed

Scooterbird, excellent, thank you.

Sakm, have not blocked India yet, but I will do so immediately. My traffic is 90% from US and UK

Re: CPU Usage abuse solution needed

Okay, sounds reasonable. What's the recommended way to trace an IP to an ASN?

Re: CPU Usage abuse solution needed

Coalman, that sounds sensible. Your advice conflicts with John Connor, who has 78 pages of networks. Wow. Who to believe (no offence intended)? :?:

Re: CPU Usage abuse solution needed

The whois lookup should contain ASN number for the network, instead of blocking France you can just block that particular network using Cloudflare. This particular number is 16276. Once you block the network any other bots on same network are denied access. Yes, I appreciate that, but I'm averse to...

Re: CPU Usage abuse solution needed

These are only instructions for if you use WordPress, not for phpBB. You didn't stop anything. WordPress has its own built-in cron and will fire off on WordPress page loads, etc. That's why if one uses WordPress it's best to create a cron on your host to fire off for your WordPress site rather than...

Re: CPU Usage abuse solution needed

Mamba, bots only follow one group so if you put this in there all the other rules do not apply. My full robots.txt is this (fairly simple) User-agent: * Disallow: /wp-admin/ Allow: /wp-admin/admin-ajax.php User-agent: BingBot Disallow: /wp-admin/ Allow: /wp-admin/admin-ajax.php Crawl-delay: 10 Site...

Re: CPU Usage abuse solution needed

You could be right, David, but I hope not. That's why I left Hostgator, for that exact reason! Anyway, rejigged all my rules on CF, added a few more countries and user agents, and so far so good. Here is my latest CPU graph for last 17 hours: cpu.png Nothing is touching the red line! 😃 Also added a ...

Re: CPU Usage abuse solution needed

But thanks for the tip on combining countries, Coalman. I somehow missed the AND/OR available in each rule I now also have dotbot (opensiteexplorer) blocked in the user agent rule. I guess one way out of this mess is to check the access file every flipping day and keep updating the CF firewall to ex...

Re: CPU Usage abuse solution needed

No, hold on, this is not a bot problem. Checking my access logs, there are no rogue bots, just the normal ones as I described above. The problem here is that under normal operating conditions, viewtopic.php is blowing CPU limits with this particular host. The host has suggested I buy "another C...

Re: CPU Usage abuse solution needed

I'm also concerned that my host, HawkHost, may be setting CPU limits that are unrealistically low for phpBB forums. Because why else is viewtopic blowing the limit? I have checked the raw access logs, and there is no sign of any one robot hammering this function thousands of times. One robot did hit...

Re: CPU Usage abuse solution needed

My site has breached CPU limits again. Unfortunately, one day later and the bots have found new ways to attack. Now I find they are trying to run Wordpress's wp-cron.php (I have stopped that by following these instructions ) Cpanel's "Resource Usage" shows me this over the last 24 hours: l...
