[coLinux-devel] connection trapper

[peter g. <plu...@p1...>]

just a quick status update on my connection trapper

currently i am using a tcp connection over an existing lan for guest->host
connection while i admit this defeats the object it is allowing me to test
the code while waiting for coserial which should provide the final method of
linking

note: stuff that doesn't use tcp or udp for example ping and traceroute will
never work on this setup

here are the planned features

outgoing tcp connections: transparent tcp level proxying

outgoing udp connections: full cone nat (see
http://www.faqs.org/rfcs/rfc3489.html for the definition of full cone)

connenection to host: any connections made to ips in the block 192.0.2.0/24
will make a connection on the host side to the corresponding ips in the
block 127.0.0.0/24

and here is the status

tcp trapping: works fine and i have even run X over it while testing with no
noticeable lag

udp trapping: i can catch udp packets and determine thier original source
port destination ip and destination port and i can send udp packets with any
combination of source and destination ips/ports i like but i still need to
write the actual nat code

special target ips: work perfectly
