NAME         top

       pppdump - convert PPP record file to readable format

SYNOPSIS         top

       pppdump [ -h | -p [ -d ]] [ -r ] [ -a ] [ -m mru ] [ file ...  ]

DESCRIPTION         top

       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
              sequences.

       -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).
