PPPDUMP(8)                  System Manager's Manual                 PPPDUMP(8)



NAME
       pppdump - convert PPP record file to readable format

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

DESCRIPTION
       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.

       -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).
