Arturaz, To me, the error is clearly reported and identified, but perhaps you overlooked it. : <stdin>:59: invalid type conversion \ : (expected size in bytes instead of rate) near ")" ^^^^^^^^^^^^^^^^^^^^^ : line 59: : $monika = class ( rate 8kbps, ceil 240kbps, burst 6kBps ) : { sfq ( perturb 10sec ); }; Try this instead: $monika = class ( rate 8kbps, ceil 240kbps, burst 6kB ) { sfq ( perturb 10sec ); }; burst is a bucket size in bits (b) or bytes (B). -Martin -- Martin A.
