I'm trying to get cepstrum coefficients

Sounds like you're interested in the filter's amplitude response. You
can get that by simply "FFTing" the impulse response. If you have Gnu
Octave or MATLAB at your disposal, enter "help freqz".

Hi,
A simpler way to do what?
What are you trying to do?

Is this obvious - not sure.
Of course I can pass white noise through the impulse response then calculate periodogram in the usual way from the time series. But is there a simpler way?
