SYNOPSISpppdump [ -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
