DESCRIPTION

34       irdadump  is  a  tool  for  monitoring  the IrDA traffic on one or more
35       links. Just write "make" to compile the program. When you run the  pro‐
36       gram, you should be able to see the IrDA traffic (if any).
37
38       One  advantage  of  implementing  IrDA device drivers as network device
39       drivers is that you should be able to attach sniffers to the device (or
40       actually  the  packet  type).  That way, it is possible to use a really
41       handy utility called irdadump (instead  of  tcpdump).  This  will  make
42       debugging  MUCH  easier.  Linux-2.2 implements the BPF (Berkeley Packet
43       Filter), so its possible to filter out exactly the frames you  want  to
44       see.   You  may  use hostname to separate different machines names.  Or
45       grep to filter the output, too.
46
47       irdadump must be run as root or installed setuid root, as  it  requires
48       root privileges.

EXAMPLES

51       The output should look something like this:
52
53       / # ./irdadump

69
70       15 packets received by filter
71       Turning on the "-d" option will make irdadump print the time difference
72       between the current and the previous frame:
73
74       / # ./irdadump -d

88       irdadump must be run as root or installed setuid root, as  it  requires
89       root privileges.
90
91       irdadump  -d  -x  -s  256  will  check the contents of the frames. This
92       should tell us if the frames have malformed content,  or  if  the  irda
93       stack is doing something wrong.
