linux - Two TCP client application with virtual interface ip -

-

here requirement.

2 tcp client connection/emulation single eth port

i created 2 virtual interface. 

 ifconfig eth1:0 10.0.0.2  ifconfig eth1:1 10.0.0.3

is possible create tcp client code such particular interface used tcp client establishment.

for example

./client_app eth1:0 - -- client ip 10.0.0.2

./client_app eth1:1 -- client ip 10.0.0.3

to enumerate local interfaces , ip address associated these interfaces use system call getifaddrs().

then use bind() system call bind local side of connection local interface's ip-address.
