Hi Didier, Could you tell me where the packet statistics for the tunnel tool compressor and decompressor are shown (from the print_decomp_stats and print_comp_stats methods)? The statistics aren't displayed when I run rohctunnel... how can the stats_comp and stats_decomp file contents be viewed? I've tried I/O redirection but that hasn't worked..
