BEGIN { format = "%-6s %-10s %-10s %-4s %-19s %-6s %-2s %-6s %-4s\n" }
{
split($1, rsp," ")
split($2, req," ")

irdadump

IRDADUMP(8)															       IRDADUMP(8)

NAME

       irdadump - monitors the IrDA traffic on one or more links.

SYNOPSIS

       irdadump [ -b ] [ -c n ] [ -d ] [ -x ] [ -s n ] [ -t ] [ -l ] [ -v ] [ -i device ]

OPTIONS

       -b dump bytes in columns

       -c n set snapcols for byte printing with -b option

       -d prints the time difference between the current and the previous frame

       -x dump frame (bytes and ascii)

       -s n set snaplen for -b and -x option

       -t force TTP decoding of unknown connections

       -l set line buffering on output file

       -v verbose

       -i device interface

DESCRIPTION

       irdadump  is  a	tool for monitoring the IrDA traffic on one or more links. Just write "make" to compile the program. When you run the pro-
       gram, you should be able to see the IrDA traffic (if any).

       One advantage of implementing IrDA device drivers as network device drivers is that you should be able to attach sniffers to the device (or
       actually  the  packet  type).  That  way, it is possible to use a really handy utility called irdadump (instead of tcpdump). This will make
       debugging MUCH easier. Linux-2.2 implements the BPF (Berkeley Packet Filter), so its possible to filter out exactly the frames you want	to
       see.  You may use hostname to separate different machines names.  Or grep to filter the output, too.

       irdadump must be run as root or installed setuid root, as it requires root privileges.

EXAMPLES

       The output should look something like this:

       / # ./irdadump
       20:11:45.412199 xid:cmd 0x0015c23b > 0xffffffff S=6 s=0

       20:11:45.572137 xid:cmd 0x0015c23b > 0xffffffff S=6 s=2

       20:11:48.822371 xid:rsp 0xf7be8388 < 0x0015c23b S=6 s=4 ACTiSYS IR100M

       15 packets received by filter
       Turning on the "-d" option will make irdadump print the time difference between the current and the previous frame:

       irdadump must be run as root or installed setuid root, as it requires root privileges.

       irdadump -d -x -s 256 will check the contents of the frames. This should tell us if the frames have malformed content, or if the irda stack
       is doing something wrong.
