It is currently not possible to do that from
Ethereal, but you can use Tethereal, the command line version
of Ethereal, to produce a similar output as in the
conversation list.
Tethereal is included in the Ethereal
distribution.
-z conv,type[,filter]
Create a table that lists all conversations that could be seen in the
capture. type specifies which type of conversation we want to generate
the statistics for, currently the supported ones are ``eth'' Ethernet ``fc''
Fibre Channel ``fddi'' FDDI ``ip'' IP addresses ``ipx'' IPX addresses ``tcp''
TCP/IP socketpairs Both IPv4 and IPv6 are supported ``tr'' TokenRing ``udp''
UDP/IP socketpairs Both IPv4 and IPv6 are supported
If the optional filter string is specified, only those packets that match the
filter will be used in the calculations.
The table is presented with one line for each conversation and displays
number of frames/bytes in each direction as well as total number of
frames/bytes. The table is sorted according to total number of
bytes.
You can try with something like
<tethereal -r infile.cap -R "eth and
!eth" -z conv,ip > statistic_result.txt
The <<<-R "eth and
!eth">>> option I use in the above example is to get just the
conversation printout without printing out all the frames .
No frames should match that condition, so just the
conversation printout is displayed.
It may be good to prepare a batch-script that takes
the input file name and runs Tethereal with the options you want and maybe also
does
all or some of the prost-processing of the
file.
<my_statistics infile.cap
Generating IPv4 conversation
printout with tethereal for the file "infile.cap" to file
"ip4stat.log"
173 ip conversations found
The formatted information is
available in file "infile.cap_ip4stat.csv" ready to be loaded into spreadsheet
