Banned user not Banned?

[cddude]

Hey all.

First of all, I hope I posted this in the correct board. If not, my apologies.


So I banned this player the other day on his IP and ID, but today I noticed that he was sitting in the afk channel in my Teamspeak.

I immediately thought that he had gotten a new IP and ID in order to join my TS server, but to my surprise both his IP and ID were matching with the ones Registered on the Ban List.

I am surprised how the Ban didn't work.

The Ban by the way is a "Regular Expression", set not to expire, and has the following "ip range" format: 12.345.*.*


Have I done something wrong? Or is my server not functioning properly?

Thanks in advance.

with regular Expressions the dot has a special meaning. You will need to enter the above Ban like this when you want to use Regular Expression: 12\.234.*
Or you should be able to use your Ban with the Wildcard Mode, which should translate it into a correct Regular Expression.

Another problem i see here.
Please do not fill all fields in 1 Ban dialog. It means ,that all fields have to match!

12.345.* < Please create a ban, with a single IP range only and do not enter a nickname or UID from that user.
Or the server will check the IP and the UID and whe nthe UD does not match, the whole ban would be usesless in this case.

Ah, I see. I thought the ban triggers were in an OR condition.

I have now separated the 2 triggers from 1 single ban record into 2 separate. Both are in the Regular Expression for now - the Wildcard for the IP seems to add some weird "/" after each number, while the Regular expression does not. What's that backslash for anyway??

So I should change the IP ban into Wildcard correct?

Also, the ban should be 12.345.* and not usual 12.345.*.* ?

Thanks for your help guys.

Oh, and by the way, is there somewhere I can read what all of these "Wildcard", "Regular Expression", etc work and in what they differ?
I run a rather big community, so it would be good to know for future use

Many thanks again.

One .* is enough for the ban as a regular expression.

.* one character + unlimuted of one character
.*.* one character + unlimuted of one character followed by one character + unlimuted of one character

Edit
http://qt-project.org/doc/qt-4.8/qregexp.html < this is explains a lot But it's not that easy to understand

[SilentStorm]

The Backslash escapes Special Meaning Characters in a Regular Expression in order to literally match that character and ignore the special meaning it usually has.

Both Wildcard IP Bans (1.2.* and 1.2.*.*) are the same as in Wildcard Mode * means any Character any amount of times. Wildcard also knows ? which means any single character.

There are plenty of Pages on the net that explains Regular Expressions, so just google for it (and/or check the Wiki Link above)

Edit to reply to dante who posted during me writing the above:

One .* is enough for the ban as a regular expression.

.* one character + unlimuted of one character
.*.* one character + unlimuted of one character followed by one character + unlimuted of one character

not true.

Both of your regular expressions match any String of characters no matter how long.

. means any Character
* means 0 or more times and is greedy which makes it match as many Characters as it can before the next Expression is evaluated.

So your first one already matches any string of any characters, they don't have to be the same! .* WILL match c5g3f9jv8FEG

And so will the .*.* because what happens is the first .* will already match the entire String, and then there is nothing left for the second . to match against BUT that is fine because you specified * which allows for the previous Expression to be found 0 times, which is true in this case and thus the regular expression matches.

Gotcha.

Thanks!

Why is my explanation not true? This is the same thing in other words :P

[SilentStorm]

It doesn't have to be "one character", nor does it have to be "+ unlimited of one character".

Each character can be different and it will match 0 Characters the same it does match a zillion Characters.
