Next time it happens, could you have a look at user agents of guest on WOL page ?
https://eab.abime.net/online.php?s=&...all&ua=1&pp=30
(not sure you can display user agent under "ip" address, see at the bottom of the page)

Goal is to find the most bad one (at least 100 simu guest from same user-agent).

Will do (once I can access the forum again). I assume we are looking for an IP address range?

[DisasterIncarna]

at least some of them have obvious names. lots of repeated entries for the "Spider" guests.

Do the other amiga forums also have a load of guests as well?

[giantclam]

Yeah, I'm hitting this now (at the time of typing) here in AU

[TCD]

Just had a talk with RCK and he changed things once again. Fingers crossed that it will improve things.

[dreadnought]

Thank you, I saw the "Sorry...." message quite often in the last few days again.

[RCK]

It's always a cat & mouse game, I ban some more bots User-Agent, and they changed them.
Fact is that our old server have not enough CPU power to reply to everyone.
So I will look to change hardware in the next few months.

Sounds like a plan I'll donate a bit towards the new server fund today.

[RCK]

Thanks TCD, but it's to soon
@others: I will made one announcement to help funding it when it will be time.

I just had the message for some minutes .. just after 10 o'clock (dk timezone).

Okay, I just find that the bots were actually into the new HOL (and not EAB).
And as HOL guest version is not 100% in cached memory, it was killing the whole server by using 100% of CPU when using search engine, game listing, etc.

So:
- I split HOL php pool from other abime.net websites
- I limited HOL ressource to 50% of server CPU max

What it means:
- If bots are coming into HOL, they will slow it down, but it won't slow down EAB of other hosted sites (winuae, etc.)
- Cached HOL pages should be displayed for guest even if bots are smashing the server (game pages for example)
- If you are logged into EAB, you will be auto logged into HOL, so it may be slow, try to switch to "private browsing" tab to see if it's better as guest

Futur:
- To be fine, we should serve to guest a full cached version of HOL (with a limited search engine for example)
- This way, every guest or bots will see a fast HOL and won't take any CPU ressources
- Regular member would have the full HOL without slow down

[TCD]

Really good that the reason has been found and that the forum is at least not affected anymore.

That would be very useful. Right now editing HOL is sloooow Hopefully that change won't take too long to implement

[RCK]

I just blacklisted the Bytespider and bytedance.com user-agent who were harvesting HOL, it should be faster for today

[TCD]

Much better now

Edit: TikTok scans HOL? Okay...

[DisasterIncarna]

any ideas what the bots are doing on hol specifically? maybe some retro emulator software harvesting screenshots for games?

I’m getting 301 moved permanently responses on my macOS machine, actually all three of them, which then redirects me back to my IP address. It’s fine on my phone though.

UserAgent for macOS been banned?

EDIT: Actually, it can’t be because wget gets the same redirect!

[SkulleateR]

Also issues with Safari here, cannot connect to either EAB or HOL

[indigolemon]

Thirding the issues connecting from OS X (using Safari or Chrome). The minute I spoof the user agent as anything other than OS X I can connect without issue.

[edit] Further testing shows I can spoof Firefox 33 under OS X and still connect without issue. Hmmm ...

[LIV2]

Also can't connect without fudging my User-Agent

I found that any UA string containing "(Macintosh; Intel Mac OS X 10_15_7)" causes a redirect to my own IP

I'm guessing that this is to mitigate the DDOS - However it should be noted that every Mac running a recent OS will report this version regardless of what version they're actually running

[DanielAllsopp]

Spoofing as anything doesn’t make a difference to me. iPad gives me the same redirect, only iPhone works.
