So I tried installing both applicable rpms with the resulting errors shown:

$ rpm --install cnijfilter-common-3.70-1.i386.rpm
error: can't create transaction lock on /var/lib/rpm/__db.000 (No such
file or directory)

$ rpm --install cnijfilter-mx430series-3.70-1.i386.rpm
error: Failed dependencies:
        cnijfilter-common >= 3.70 is needed by

        libcnnet.so is needed by cnijfilter-mx430series-3.70-1.i386
