Forums Scripts & Popups DCC protocol

Hey.

Iam currently working on a script which will support DCC on sockets that will be opend by mIRC to an IRC-server.

But Iam kind of stuck when it comes to the file-transfers (receiving, not sending). It connects and it also reads/writes to the file but the problems are:

1 - It doesnt send information back to the server so the progressbar for the client(server) which is sending does not update (it doesnt send information back because I do not know what to send back
2 - All the files get corrupted (it writes everything it gets from the socket to the file with /bwrite)

Thank you in advance.

You dont dcc send/rercieve through the irc server tho!

PS: from mempry the reciever of the file is ment to send back acknoldge messages that i think are the amount of file recieved, might be in bigended order, but would have to check, its somewhere in the mirc help file from memory.

Since the connection is made between 2 computers, one of them needs to be the server. I was refering to this server(which is the person who requests the send to the person and thus listens), and not the IRC-server.

Ok, I found out what to send back exactly. I need to send a package back to the person that is sending in a network-byte format, which can be converted with $bvar and it's "nlong" property. Could someone give me an proper example of how to convert an integer to network-byte format. I tried and did not succeed.

Thank you in advance~

re: IRC-server
Well you said irc server not me. ~


re: the rest
Network byte order is simiply the order in which bytes of a larger value occur, its also called Bigendien (Most significatnt byte first to least significant byte last)
FYI the x86 processors use LSB to MSB order (the opersite)

Simply put , take a value and convert it to its equivilant 4 byte binary value, then order the bytes with the most significant byte first

examples
7 = 0 0 0 7 = 0 x 256^3 + 0 x 256^2 + 0 x 256 + 7
1678052209 = 100 5 11 113 = 100 x 256^3 + 5 x 256^2 + 11 x 256 + 113

The order shown here is the order they need to be transmitted in.

Hope this helps.

This all seems like a riddle to me XD


Could you explain how you got those numbers from that value with a mirc-script?

Thanks.

I think you use $longip

I did show u "1678052209 = 100 5 11 113 = 100 x 256^3 + 5 x 256^2 + 11 x 256 + 113"

do u not know what 256^3 means?

1678052209 = (100 x 256 x 256 x 256) + (5 x 256 x 256) + (11 x 256) + (113)

Mikechat uses a clever method of getting them, which is infact exactly what an ip x.x.x.x is a big number broken into bigendien order with dots between it.

/bset &binvar 1 $replace($longip(1678052209),.,$chr(32))
