NAME
irdaping - sends IrDA test frames SYNOPSIS
irdaping [ daddr ] [ -s framesize ] OPTIONS
daddr ... -s framesize ... DESCRIPTION
This is a program similar to ping(8). It sends IrDA test frames (added some userdata which contains the frame number and the time the frame was sent). You can change the size of the frame by using the -s option. To get daddr you may use irdadump. irdaping must be run as root or installed setuid root, as it requires root privileges. EXAMPLES
irdaping <daddr> [-s <framesize>] You may use an alias, which does not use any parameter alias irping="irdaping `grep daddr /proc/net/irda/discovery|sed s/.*daddr://`" It works fine when there is only one discovered client. DIAGNOSTICS

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 20:11:45.492137 xid:cmd 0x0015c23b > 0xffffffff S=6 s=1 20:11:45.572137 xid:cmd 0x0015c23b > 0xffffffff S=6 s=2 20:11:45.652208 xid:cmd 0x0015c23b > 0xffffffff S=6 s=3 20:11:45.732137 xid:cmd 0x0015c23b > 0xffffffff S=6 s=4 20:11:45.812137 xid:cmd 0x0015c23b > 0xffffffff S=6 s=5 20:11:45.892175 xid:cmd 0x0015c23b > 0xffffffff S=6 s=255 Linux 20:11:45.902362 xid:rsp 0xf7be8388 < 0x0015c23b S=6 s=5 ACTiSYS IR100M 20:11:48.412197 xid:cmd 0x0015c23b > 0xffffffff S=6 s=0 20:11:48.492656 xid:cmd 0x0015c23b > 0xffffffff S=6 s=1 20:11:48.572177 xid:cmd 0x0015c23b > 0xffffffff S=6 s=2 20:11:48.652169 xid:cmd 0x0015c23b > 0xffffffff S=6 s=3 20:11:48.732177 xid:cmd 0x0015c23b > 0xffffffff S=6 s=4 20:11:48.812153 xid:cmd 0x0015c23b > 0xffffffff S=6 s=5 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 -d 20:11:18.412475 (0982.06 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=0 20:11:18.492345 (0079.87 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=1 20:11:18.572376 (0080.03 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=2 20:11:18.652979 (0080.60 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=3 20:11:18.732354 (0079.38 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=4 20:11:18.755093 (0022.74 ms) xid:rsp 0xf7be8388 < 0x0015c23b S=6 s=3 ACTiSYS IR100M 20:11:18.812350 (0057.26 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=5 20:11:18.892518 (0080.17 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=255 Linux 20:11:21.412486 (2519.97 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=0 20:11:21.492395 (0079.91 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=1 20:11:21.572368 (0079.97 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=2 20:11:21.652405 (0080.04 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=3 20:11:21.732458 (0080.05 ms) xid:cmd 0x0015c23b > 0xffffffff S=6 s=4 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.
