What's that with the Sucuri Website Firewall?

If, for example you tried to post ">10..." it won't let you (sometimes) unless you put a space in after the > symbol.

It just let me do it now, though...

The quirkiness of Old Sucky is one of the many "endearing" features of the Forum,.

Learn to live with it..... The owners aren't hugely responsive to "issues". That said, it's a lot better than it once was...

Glenn, I don’t think I have seen any instances where the > causes the Sucuri firewall to pop up. I think what you are referring to is the <
That frequently causes the the Sucuri firewall to pop up.

You would never normally get something like _..

<1000

_..to post without the Sucuri firewall to popping up.

That is the most common character combination that we see causing the Sucuri firewall to pop up: It is is the < followed by 4 or more characters. The reason why I say characters in italics is that that statement is not strictly correct: That is because not all characters after the < cause the problem. The space is one “character” that doesn’t cause the Sucuri firewall to pop up.
So <100 or < 10 or <10 0 or <10 are all OK: You see I have broken up the 4 forbidden characters with an allowed character. ( A space is an allowed “character” )
The most common workaround we suggest is to add a space after the <
So < 1000 is OK – here Sucurri sees as the first 4 characters after the < as < 100

The other workaround which I used above to get <1000 to post in this forum post is to break up the 4 forbidden characters with another allowed character which is the [
That [ is used for a BB CODE tag, so you can do the “Black character trick” to get <1000 to post:
What you post is this, (which is the normal way in BB Code in making one of the characters black)
<10[color=Black]0[/color]0

Sucuri firewall works on what you have in the editor before you post and not what you finally see. So it accepts <10[color=Black]0[/color]0
As far as Sucurri is concerned, it sees as the first 4 characters after the < as 10[c
The allowed [ has cured the problem

That is also a way to get rude words past the sensor… Of course, Glenn, we wouldn’t fucking do that, would we?


Here some references to the < problem and the other things Sucuri firewall dose not like:

Once you know about these little “fun” characteristics, and the work arounds, you almost grow fond of them – they add a sort of imperfect human character to the forum , ….

Hi ysdai7287,
I have sometimes experienced the Scuri Website Firewall shooting me down when I "Go Advanced" or "Post Quick Reply" . Usually that is just temporary and if I have another go, and / or refresh the page and have another go then all is well.
But Important : Always copy the contents of your reply window to the clipboard before hitting "Go Advanced". This precaution is a good idea as another inconsistent forum Bug is that reply contents can vanish without trace when doing things like Editing or Going Advanced. (If that does then happen, then you can then paste your back up from the clipboard)

( Alternatively prepare all your posts in WORD or a text document , ( then copy them to the forum editor when ready to post) as many of us do, so you always have a back up )

Hi ysdai7287
You is welcome. If you ever pin down a new specific thing that causes the Sucuri Website Firewall to pop up, then let us know.. we must make a list of them and the workarounds sometime….

I think the general reason for the Sucuri Website Firewall being in place is to stop people / spammers trying to insert / inject bits of SQL code or similar. …. - Some of the less common reported problems are when you use words or word combinations like SQL commands. You will find those in the referenced links, but they are much more tricky to pin down.
( Regardless of what actually trips the Sucuri Website Firewall, it usually gives a message saying forbidden HTML. Also it usually says some incorrect crap about what browser you are using. So the messages and report it gives you is not to be taken too seriously )

P.S. if you have problems posting and want to experiment first before posting “for real”, or if you want to experiment generally with these and any other posting problems, then you can start a test Thread here: https://www.excelforum.com/development-testing-forum/
Just give the Thread a Title like “Just testing, no reply needed”. ( You have to be logged in to “see” that Sub Forum.) You can practice and test any posting stuff there

Hi
No, .. I was hoping to get around to doing it sometime.. The URL list in Post #5 contains, I think, most of the reported problems, at least the ones I have noticed reported or experienced myself.
(Some of those threads there report / talk about the same problem).

If you come across anything new, then pop a reply in this Thread ( you are allowed to "Add solutions to existing threads even if they are Solved - it does not then come under the forbidden "High jacking" of a thread). I am subscribed to this Thread, so I will catch any additions you make.
Thanks
Alan
