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).
