CTCP not working on eggdrop 1.8 but works on 1.6

Autrui · Post by **Autrui** » Wed Jun 15, 2016 2:03 pm

Hi,

I have three eggdrops, two 1.6 and one 1.8.
They are on my server, and I'm using both ZNC (bouncer, also on my server) and my own connection.
When I /dcc chat, they all respond correctly. But when I /ctcp chat, only the 1.6 eggdrops responds.
The 1.8 eggdrop opens the connection and closes it right away :

Acknowledging chat request...
-
Unable to connect
-
DCC session closed

I'm using the range port 1024:1029 in order to /dcc chat with mIRC.

More details :

For my first eggdrop with my connection at home(1.6), here are the details of the connection :

Here we are. The CTCP Chat doesn't work on my 1.8 eggdrop. But I don't understand why. The only difference between the second (1.6) and the third (1.

eggdrop is the set my-ip "server-ip" that has became set vhost4 "server-ip".

I really don't understand why there is this problem.
If someone could find some hints and help me... Thanks !

Alright, I will be replying to myself. Thanks to jack3, I found the problem.
The 1.8 eggdrop didn't have the set nat-ip parameter set. Both of the 1.6 eggdrops don't have it either, but it stills works with them.

We found the problem 'cause my 1.8 eggdrop was giving me the 127.0.0.1 IP when i /dcc chat it. When setting the nat-ip parameter, it was then giving the correct IP.

That's it...

I'm still looking for the reason, about why I need to set it on 1.8 but not on 1.6. So... If anyone has the answer, please tell me !

Thanks !

It is your server problem... It happens with me... I ask my provider to change server location... After that problem was solve.
