sockets - Communication between Android emulator and Fedora 18 VM -

i have problem interconnecting android emulator fedora 18 running on virutal machine. both run on same host , i'm trying create socket connection between these. i'read several threads on issue of interconnecting 2 emulator instances. did changes according this did not work. linux machine server listening connections emulator. did have problem? or adivce?

update: command listening incomming connections on linux vm , sending x variable:

x=$(filename); echo $x | nc -l 10.0.2.15 -p 4460. 

this command emulator stucks when creating connection:

socket = new socket("10.0.2.2", 4450); 

i did redirection on vm:

iptables -t nat -a prerouting -i p2p1 -p tcp --dport 4450 -j redirect --to-port 4460 

thanks.
