good idea ! I would have never tought to do that.
It's works well, when I am home. But at school, I am behind a NAT too, and it will not work... anyway, great job and thx you a lot.

DCC Chat not working

2003-08-16T13:32:38-04:00

ahh, damn, sorry about that...I've been basing making requests on a script I wrote that hooks up an eggdrop to a Services DCC connection...and eggy is listenening on the port :/

ok, try 2
disconnect from the chat server. in mIRC, go to:
options->Conenct->Local Info

set localhost and IP address to your *internal* IP. UNCHECK the boxes for "On connect, always get:"

only problem with doing it this way is that you will be unable to DCC anyone else untill you log off, re-check the boxes, but will atleast get you a DCC connection...

what NAT software are you using? there might be an easier way, but really depends on what options are available on the NAT...

it s getting hard

2003-08-16T11:03:19-04:00

Well, it try what you said. But is not a dotted ip address format, but a long ip address. So I write a small program to convert my internal ip address in long format (it's the inverse dotted ip address ie with 214.135.212.65 you need to convert 65.212.135.214...).
I can see in logs that dns resolve well the long ip address in the correct dotted ip one. But it doesn't work anymore...

I am getting crazy...

syntax for DCC chat request:

Code:

PRIVMSG  :\1DCC CHAT chat  \1

where:
is the IP address you request that the target connect to
is the port that they should connect to.

DCC requests are set up for the security of the user who is being asked to connect. the actuall connection is opened by the target, not the person requesting. the protocol requires that the target open a connection with that designated port at that designated IP, if the request is accepted. because of the way NAT firewalls work, when the bot tries to open a connection to your external IP from inside, it fails.

basicly, DCC chat requests are just CTCP requests...and CTCP messages are just PRIVMSG (/msg)...mIRC and other clients just use the \1 character to signal a special meaning.

one good way to lear about how to form a DCC request (and be able to copy and paste it with the internal IP) is by using a debug window in mIRC.

/debug -np @moo

this gives you a raw view of all input and output for mIRC.

hope this helps make some sense of it all

How do i do ?

2003-08-16T06:11:08-04:00

I don't understand exactly why it doesn't work. I forward a range of ports to my PC (where mirc is running). So when a DCC Chat is requested, the request if forwarded to mirc (it works when the bot is on a remote computer not in the same NAT). And it doesn't work... But when I send a DCC Chat request, i send the IP i used to connect IRC Server, don't I ? So it's should be my external IP (when i whois me, i see my external IP).

Whatever, I would like to send my internal IP in DCC Chat but i didn't find how to do it.

ahh, k, I follow then...try this from behind your NAT:

/quote PRIVMSG botnick :\1DCC CHAT chat 192.xx.xx.xx 6661\1

where 192.xx.xx.xx is your *internal* NAT IP ( the \1 is ascii character 0x001...^A I think in mIRC?)

let me know it it works...have a few other tricks lol

roland
No, nice try but it doesn't work. mirc send my external address IP for the dcc chat. no way to put my internal IP on the fly...

But I think (I hope...) the solution is in eggdrop side, not mirc.

that's what I'm saying, mIRC is sending your external IP. you will *have* to send the dcc request manually using your internal IP - mIRC has no way of knowing that the bot is on the same side of the NAT as you, and neither does the bot, because the message you are sending it is coming from outside the NAT (the chat server).

did you even try it?

Maybe you need to do some port forwarding

I explain better

2003-08-14T19:16:38-04:00

|IRC server|
|
|________|NAT BOX|---|EggDrop on Nat Box|
\
\
|Me with mIRC|

It s the exact archi that I use. A eggdrop (1.6.15) is running on my NAT box (Debian).
And when I am behind my NAT Box or behind another NAT (at my office for example), it's the same problem:

Code:

In logs: [01:14] DCC connection: CHAT (Me!~me@myip.com)[01:14] net: connect! sock 9[01:14] net: eof!(read) socket 9[01:14] Lost dcc connection to Me (~eppo@myip.com/4026)

But when I am on a remote computer (a NAT box for example), it works, i access to the party line

yes but there's a connection track module in linux kernel which let use ftp and irc connection through NAT box. Doesn't work ?

let me make sure we're on the same page here :/ I get confused easy

|IRC server|
|
|________|NAT BOX|
/\
/ \
|mIRC|__/ \__|Egg|

mIRC client machine and Egg are both behind NAT, seperate machines? Then would beed to send a modified DCC Chat request, using the internal IP of the mIRC client machine. that way, the egg knows not to try to connect to the NAT itself, which is the only computer in of the network that actually has that external IP.

*scratches head....* I think that's what you're question was lol

if both you and your bot are behind the same NAT, you would use the internal IP to dcc chat. what's happening is you are connecting to an external IRC server, so sending your external IP in the dcc request. but you are not external to the bot...

well if you are on NAT.. and trying to dcc chat it from the same box the bot runs on.. Then telnet is your best friend....

That's mean that if you are behind your NAT box and the egg on that NAT box, you can't DCC Chat ??
That's annoying...
is there a solution except dawn telnet ?
