The pppdump utility converts the files written using the record
option of pppd into a human-readable format. If one or more
filenames are specified, pppdump will read each in turn;
otherwise it will read its standard input. In each case the
result is written to standard output.
The options are as follows:
-h Prints the bytes sent and received in hexadecimal. If
neither this option nor the -p option is specified, the
bytes are printed as the characters themselves, with non-
printing and non-ASCII characters printed as escape
-p Collects the bytes sent and received into PPP packets,
interpreting the async HDLC framing and escape characters
and checking the FCS (frame check sequence) of each
packet. The packets are printed as hex values and as
characters (non-printable characters are printed as `.').
-d With the -p option, this option causes pppdump to
decompress packets which have been compressed with the
BSD-Compress or Deflate methods.
-r Reverses the direction indicators, so that `sent' is
printed for bytes or packets received, and `rcvd' is
printed for bytes or packets sent.
-a Prints absolute times.
-m mru Use mru as the MRU (maximum receive unit) for both
directions of the link when checking for over-length PPP
packets (with the -p option).
