If there's a better way I'm in no rush figure it out. +# +# Firewalled sysreset fserves try to open a dcc chat connection to the target port and send +# the message "100 fservenick". After the fserve sends the "100 fservenick" message it expects a +# "101 recipientnick" message, with "recipientnick" being the nick of whoever got the message. +# I wasn't able to send it some1 else's nick and get a connection that way, which would be +# interesting since you could theoretically serve connections to other ppl behind firewalls. +# +# This code requires opening a listening socket, but since sysreset is mircx specific (essentially +# winhozed specific) it doesn't hestitate to asking people who connect to open a listening port in +# the well known/privileged range which requires root (NONO). To deal with this, I setup iptables +# to forward packets bound for port 59 to port 12345 (which can be bound by non-root) by using: +# "iptables -t nat -I PREROUTING -p tcp -m multiport --dports 59 -j DNAT --to-destination :12345" +# (this requires root) +# +# There also appears to also be an option for some firewalled dcc send protocol.
