NAME
cansniffer - manual page for cansniffer 2023.03-1
SYNOPSIS
cansniffer [ can-interface ]
DESCRIPTION
cansniffer - volatile CAN content visualizer.
OPTIONS
|
-q |
(quiet - all IDs deactivated) |
-r <name>
(read sniffset.name from file)
|
-e |
(fix extended frame format output - no auto detect) |
|||
|
-b |
(start with binary mode) |
|||
|
-8 |
(start with binary mode - for EFF on 80 chars) |
|||
|
-B |
(start with binary mode with gap - exceeds 80 chars!) |
|||
|
-c |
(color changes) |
-f <mode>
(CAN FD mode: 0 = OFF, 1 = ON, 2 = auto detect, default: 2)
-t <time>
(timeout for ID display [x10ms] default: 500, 0 = OFF)
-h <time>
(hold marker on changes [x10ms] default: 100)
-l <time>
(loop time (display) [x10ms] default: 20)

Use interface name ’any’ to receive from all can-interfaces.
commands that can be entered at runtime:
q<ENTER>
- quit
b<ENTER>
- toggle binary / HEX-ASCII output
8<ENTER>
- toggle binary / HEX-ASCII output (small for EFF on 80 chars)
B<ENTER>
- toggle binary with gap / HEX-ASCII output (exceeds 80 chars!)
c<ENTER>
- toggle color mode
@<ENTER>
- toggle ASCII output (disabled for CAN FD by default)
<SPACE><ENTER>
- force a clear screen
#<ENTER>
- notch currently marked/changed bits (can be used repeatedly)
*<ENTER>
- clear notched marked
rMYNAME<ENTER>
- read settings file (filter/notch)
wMYNAME<ENTER>
- write settings file (filter/notch)
a<ENTER>
- enable ’a’ll SFF CAN-IDs to sniff
n<ENTER>
- enable ’n’one SFF CAN-IDs to sniff
A<ENTER>
- enable ’A’ll EFF CAN-IDs to sniff
N<ENTER>
- enable ’N’one EFF CAN-IDs to sniff
|
+FILTER<ENTER> - add CAN-IDs to sniff |
||
|
-FILTER <ENTER> - remove CAN-IDs to sniff |
FILTER can be a single CAN-ID or a CAN-ID/Bitmask:
single SFF 11 bit IDs:
|
+1F5<ENTER> - add SFF CAN-ID 0x1F5 |
||
|
-42E <ENTER> - remove SFF CAN-ID 0x42E |
single EFF 29 bit IDs:
|
+18FEDF55<ENTER> - add EFF CAN-ID 0x18FEDF55 |
||
|
-00000090 <ENTER> - remove EFF CAN-ID 0x00000090 |
CAN-ID/Bitmask SFF:
|
-42E7FF <ENTER> - remove SFF CAN-ID 0x42E (using Bitmask) |
||
|
-500700 <ENTER> - remove SFF CAN-IDs 0x500 - 0x5FF |
||
|
+400600<ENTER> - add SFF CAN-IDs 0x400 - 0x5FF |
||
|
+000000<ENTER> - add all SFF CAN-IDs |
||
|
-000000 <ENTER> - remove all SFF CAN-IDs |
CAN-ID/Bitmask EFF:
|
-0000000000000000 <ENTER> - remove all EFF CAN-IDs |
||
|
+12345678000000FF<ENTER> - add EFF CAN IDs xxxxxx78 |
||
|
+0000000000000000<ENTER> - add all EFF CAN-IDs |
if (id & filter) == (sniff-id & filter) the action (+/-) is performed, which is quite easy when the filter is 000 resp. 00000000 for EFF.
