version reply is empty ? what is regex

Please take a look at http://forums.unrealircd.com/viewtopic.php?t=3203

It isn't possible using a spamfilter!

In this case - it is possible.
There is a difference between no version reply and an empty version reply. Notice that a version string IS in fact being sent back - it simply appears to contain nothing.

(I say appears to because it could very easily consist of whitespace. Or it could use color codes to make the version text the same color as your bg color. The regex considers only the spaces-only situation. Colors can't be checked for in regexes since they get stripped.)
-or-

/spamfilter + n gline - Empty_version_string. ^\x01VERSION \s*\x01$

Code: Select all

spamfilter {
    regex "^\\x01VERSION \\s*\\x01$";
    target private-notice; // CTCP replies are sent via NOTICE.
    action kline;
    reason "Empty version string.";
};

-or-

/spamfilter + n gline - Empty_version_string. ^\x01VERSION \s*\x01$

= no

Regex is like a way more powerful version of wildcards. It allows you to do text matching with a good deal of accuracy and selection. Pretty awesome.

Well by that definition alone you could say wildcards are regexes! :P

</obligatory>

But wildcards dont match the "certain syntax rules" =P

in server send /ctcp nick version good pozitive

but!!!! nick connect server negative? why?

help me pleas?

1. Your regex isn't valid.
2. Your regex is too broad and would not let ANYONE connect.

aquanight's example should work perfectly

Then why not? If you don't want to accept our help and give us reasons why it won't work, I see no reason to keep this topic open...
