    Doing "netstat -b" i get some connections as below:
    Code:
     Proto  Local Address               Foreign Address               State
     TCP    10.215.19.74:50330     channel-02-07-snc1:http  TIME_WAIT
     TCP    10.215.19.74:50331     channel-02-07-snc1:http  TIME_WAIT
     TCP    10.215.19.74:50333     www-12-02:http              TIME_WAIT
     TCP    10.215.19.74:50344     80-239-206-50:http          TIME_WAIT
     TCP    10.215.19.74:50359     channel-02-07-snc1:http  TIME_WAIT
     TCP    10.215.19.74:50360     channel-02-07-snc1:http  TIME_WAIT
     TCP    10.215.19.74:50374     channel-02-07-snc1:http   FIN_WAIT_2
    There's no executables displayed for these connection. What could be these connections?

    Well if you are on a Linux box, using lsof can map open files to processes using them and since sockets (as well as everything else) is treated like a file you can use that to see who has what socket open..

    the -b switch only works for Windows XP and beyond. Not other Windows operating systems and Linux.
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    Possibly, you could also log all outgoing traffic on your firewall, depending on what you are using.
