pppdump - convert PPP record file to readable format
pppdump [ -h | -p [ -d ]] [ -r
] [ -a ] [ -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, 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.
- -a
- Prints absolute times.
- -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).
