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
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).
