The grep search expression should be a part of the real RPM name in this
case, to make sense this way. So if you look for all RPMs installed with
"gnome" in their name:

rpm -qa | grep "gnome"

If you know the exact name of the program in question

rpm -q iptraf

is much more efficient as it does not first lists all rpm registered
packages and then filters output of the list with grep.

"man grep" :) will point you to parameter "-i"

By the way, you can too use "yum list installed". It takes to regular
expressions, see "man yum":

yum list installed [regexp1] [...]
