pppdump - convert PPP record file to readable format
pppdump [ -h | -p [ -d ]] [ -r ] [ -m mru ] [ file ... ]
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, inter-
preting the async HDLC framing and escape characters and check-
ing the FCS (frame check sequence) of each packet. The packets
are printed as hex values and as characters (non-printable char-
acters are printed as `.').
-d With the -p option, this option causes pppdump to decompress
packets which have been compressed with the BSD-Compress or
-r Reverses the direction indicators, so that `sent' is printed for
bytes or packets received, and `rcvd' is printed for bytes or
-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
