Well at least I got a reply. Yes I am very aware of Dalnets issues. There are plenty of other people I know on dalnet who have no problem like this. So it is a stretch for me to assume it is them. I know they are getting attacked, but this really (and even you should agree) shouldnt even matter. The fact that it happens on random servers is normal for this problem, but a DCC has only the slighest bit of conversation with the server. Doing more tracking in Ethereal (an excellent Packet Tracker) I have found that it is sending the send file message to the wrong ip address. Now, a real one it seems 66.12.202.2, however this is not the IP or the DNS IP or the WHOIS IP of the person I was sending to. The IP has no relation as far as I have been able to tell.
I appreciate your response, and I am sure the '2 liners' do help with some problems, but about 30 threads sent me there to read - Johnny picks up the phone, Nobody's there! Opps dial-tone. Well I can just figure how a disconnect works.
Thanks for you Help - I am a loyal mIRC user.
