Irene can take a look at this tomorrow . I guess you have a preferred capture
interface, right? We put this interface on the ifaces list, since
it is equivalent to specifying it on the command line.
The same problem should occur when you specify interfaces on the command
line. So ifaces is set correctly (at least as intended), I think the
condition is wrong.
