How to set default ethernet interface to eth2

GNU Radio
1

Hi,
I’m running GNU Radio 3.3 from within a Fedora 12 x86 64-bit
virtual machine using VMware Fusion on Mac OS X 10.6.4.

I’ve configured a second ethernet interface, and tested communications
with the USRP2 using the following command

find_usrps -e eth2

Now, the thing is other commands like usrp2_probe all default to using
the eth0 interface, it didn’t accept a -e eth2 option.

How can I tell GNU Radio to only use the eth2 interface for all
communications with the USRP2, instead of eth0?

For python scripts you change the defaults by modifying:

gnuradio/gr-usrp2/src/usrp2.i

For the four blocks change std::string ifc=“eth0” to std::string
ifc=“eth2”
and recompile

This assumes the script doesn’t explicitly state eth0

Cheers,
