Sanjay:
Heya. Any chance you've seen/heard/come-across the
echoWare toolkit?
ftp://ftp.echogent.com/EchoWare/src/EchoWare_SDK_1.88.zip
It's not a true peer-to-peer system, in that the two
end-user sides of the connection both maintain a persistent TCP
connection with a packet relay-server -- if the relay-server
goes down, so do any end-to-end data connections. This is
unlike a system like Hamachi (and many others), in which a
central server helps with connection initiation (as described
pretty well in that Bynosaurus paper), but isn't required for
the data connection thereafter.
Still, there's a test-program in the SDK, and it may
prove an interesting start. We wrapped it up pretty well with
VNC software, and sell it as a remote-desktop system which
IT support providers can own and operate themselves. Happy
customers, pays the bills, win-win. :)
cheers,
Scott

Hi,
I am sure there must be something similar to what I am asking, but
after a good search and reading many posts I have'nt come to any
understanding.
Firsty I have some knowledge of NAT and I have an environment where
clients are sitting behind NAT's configured with iptables. And I read
this excellent article on p2p communication over NATs called
"Peer-to-Peer Communication Across Network Address Translators"
(http://www.brynosaurus.com/pub/net/p2pnat/).
After several tries, I havent even progressed an inch in communicating
from peer to peer. since my NAT s/w is IPTABLES, does it support such
a feature of NAT traversal ? And is there any way of using TCP to do
the NAT traversal ?
I have studied Skype for this effect, and I have seen that it isnt
working with UDP (in my NAT environment atleast), all TCP
communications, on port 80 and 443. I am new and bewildered. I need
some direction, as how to progress, in writing a simple p2p
communication over NAT.
sorry for the dumb post, if it sounds like one, I am absolutely a
newbie in this field.
