Some commands to dump informations.
 | ||
dump packetName ?startMapper? ?tabSize?
| hexdump+mappers
|
|
| |
Dump the packet memory content in hexa and pretty the output of all the defined
mappers. The first mapper used to decode the packet can be specified (default is
ethernet). The default tab size is 4, but can be forced by user.
|
|
| ||
| ||
dumphex bytesarray ?start_offset? ?size?
dumptext bytesarray
| hex dump
packet in text
|
|
| |
The first command produce an hex dump of the given data.
The data are dump as lines of size bytes, with optional starting offset value set,
as shown below :
% dumphex [string repeat \x00 32]
00000000 00 00 00 00|00 00 00 00|00 00 00 00|00 00 00 00 ................
00000010 00 00 00 00|00 00 00 00|00 00 00 00|00 00 00 00 ................
The second one dumps the data in a text made of \x?? (useful
as input of the "setfrom" command). Example of output :
% dumptext "\x00\xa0\x24\xa6\xdc\x69\x00\xa0"
\x00\xa0\x24\xa6\xdc\x69\x00\xa0

dumpraw packetName
dumpraw2 packetName
| hex dump
packet in text
|
|
| |
The first command dumps the packet memory content in hexadecimal. The data are dump as lines of
16 bytes and ASCII representation is given too, as shown below :
% dumpraw pkt
00000000 00 00 00 00|00 00 00 00|00 00 00 00|00 00 00 00 ................
00000010 00 00 00 00|00 00 00 00|00 00 00 00|00 00 00 00 ................
The second one dumps the packet memory content in a text made of \x??
(useful as input of the "setfrom" command). Example of output :
% dumptext pkt
\x00\xa0\x24\xa6\xdc\x69\x00\xa0
|
|
| ||

dumpmappers packetName ?exclusionFilter?
dumpmapper packetName mapperName
| mappers
mapper
|
|
| |
Pretty the output of all the defined mappers or of the given mapper. If an exclusion filter
is given, all the mappers matching agains the string (using * and ? as wildwards) will
not be included in the output.
When dumping mappers, the 'ondemand' types of shown as offset to their content. This can be
change by setting the global variable doExpandOnDemand to maximum depth you want to be
expanded. The array can also be turned of by setting then global variable doExpandArray to 0,
a positive value indicates the maximum depth to which expand the arrays.
When dumping a mapper, the name is followed size the lower, upper bound and size of the mapper as
shown in the example below :
% dumpmappers pkt
<ethernet> == [0:13/14]
-src 00:a0:24:a6:df:18
-dest 00:a0:24:a6:dc:69
-type ip (2048, 0x800)

zlib::compress data ?level?
zlib::uncompress data
| compressed data
uncompressed data
|
|
| |
Compress and decompress data using Zlib 1.1.3.
|

Some commands to control a slave. This is a wrapper around a socket established between
two hosts (a slave and a master). You can for example connect the two hosts using a
serial line (with SLIP or PPP) to do some tests without disturbing the tested network ...
| ||
remote::init:master addr port
remote::init:slave addr port
| socketName
socketName
|
|
| |
Wrapper to the socket command. Used to establish a communication channel between the master
and the slave.
|
|
| ||
| ||
|
|
| |
Send a script composed of commands to be executed on the slave.
|
|
| ||
| ||
remote::answer ?timeout?
| answer
|
|
| |
Wait a answer from the slave. The default timeout is 5 seconds, but can be
specified as second argument.
|
|
| ||
| ||
remote::execute ?timeout?
|
|
|
| |
Wait a script and return the result after executing.
If no script is received in 300 seconds, returns the string "timed_out".
You can for example enclose this command in an infinite loop on the slave.
|
|
| ||
Some commands to log the result of some actions.
| ||
log::init:full filename
log::init:summary filename
|
|
|
| |
Initialize the file descriptor used to record the logging events. 'stderr' or
'stdout' can be used.
If these functions are not called, the default is set to 'stdout' for the
full log and nothing for the summary log.
|
|
| ||
| ||
log::packet pkt
log::mappers pkt
log::text message
log::full message pkt
log::summary message
|
|
|
| |
All commands but log::summary send their output to the full log. They log les raw
hexadecimal dump, the mappers (pretty-printed), a user defined text or a message
followed by a full dump (raw+mappers).
The last command send a simple message to the summary log.
