Hi. In my server a lot of bots are attacking. their version reply is : [11:11] [asd VERSION reply]:

i can not ban them with using ban version block in unrealircd.conf

how can we ban the blank versions with ban version block. what must i write into.

i tried mask ""; and mask " "; but they don't work.

please help thank you.

Simple answer is you cant ban blank version replies. Also the ban version block is ineffective where the client does not send a CTCP version reply at all as well.

I dont know how you'd do it but you could use a bot to request the CTCP version reply and have it detect blank replies and take appropriate actions.

ive made a addon for mirc that detected blank version replies,
it simply looked for if ($2 == $null || (!$2)) { }

i dont however think its blank, i wouldnt be suprised if there is a space or if there is a control code in there, otherwise the client would return a error when compiled (would it?)
