[...]Both the commands were run for 10 secs. In fact I ran the command with -w option for 15 secs but still the captured packets in the dump are are just 6 compared to 26 packets without the file save option. Any reason ? What I can I do to capture all ?

Sounds like some bottleneck in the system, perhaps a problem with the buffers. Try

Hi,
I am stuck with a tricky situation in which one of my applications is flooding the network with UDP messages. The architecture of the application is not supposed to do so. Neither is there any place where the application will go into an infinite loop sending UDP messages over the network. To... (3 Replies)

Hello,
SNMP reports from my Linux server a large number of "ipInAddrErrors" on several of my systems. According to one description, these packets are discarded datagrams due to:
How do I determine what packets these are? Can tcpdump help? If so, can anyone suggest a filter? (1 Reply)
Hi guys,
I'm using a Linux system(Ubuntu) and I've been trying to find a method to read the total packets received/sent on a specific port (e.g port 80 or port 25) on a local machine. I can read the overall total packets received/sent from the /proc/net/dev file system. But what I can't do is... (2 Replies)
Hi,
I want to capture a certain type of packets (selected according to the protocol) coming to my PC and then transmit them to another PC. I had the idea to use tcpdump to filter input packets and extract those chosen. Well my questions are:

driftnet
DRIFTNET(1) General Commands Manual DRIFTNET(1)NAME
driftnet - capture images from network traffic and display them in an X window; optionally, capture audio streams and play them.
SYNOPSIS
driftnet [options] [filter code]
DESCRIPTION
Driftnet watches network traffic, and picks out and displays JPEG and GIF images for display. It is an horrific invasion of privacy and
shouldn't be used by anyone anywhere. It has been described as `a graphical tcpdump(8)', `EtherPeg for Unix', and called all sorts of nasty
names by people on Freshmeat. It is also possible to use driftnet to capture MPEG audio data from the network and play it through a player
such as mpg123(1).
Images may be saved by clicking on them.
OPTIONS -h Print a summary of usage.
-v Print additional details of packets captured to the terminal.
-b Beep when a new image is displayed.
-i interface
Listen to packets on interface. By default, driftnet will try to pick up traffic on all interfaces, but this does not work with all
versions of pcap(3); on such systems, an interface must be specified. On some systems, driftnet can only use promiscuous mode if an
interface is specified.
-f file
Instead of listening on an interface, read captured packets from a pcap(3); dump file; file can be a named pipe for use with Kismet
or similar.
-p Do not put the interface into promiscuous mode.
-a Operate in `adjunct mode', where driftnet gathers images for use by another program, such as Jamie Zawinski's webcollage. In this
mode, no window is displayed; images are captured and saved in a temporary directory, and their names written on standard output.
-m number
In adjunct mode, silently drop images if there are more than number in the temporary directory. It is assumed that another process
will delete images which it has processed.
-x prefix
The filename prefix to use when saving images, by default `driftnet-'.
-d directory
Use directory to store temporary files. Driftnet will clear this directory of its own temporary files on exit, but will not delete
the directory or any other files.
-s Attempt to capture streamed audio data from the network, and either play it or, in adjunct mode, save it in files. At present this
only works with MPEG data.
-S Capture streamed audio data only, ignoring images.
-M command
Use the named command to play MPEG audio data. The command, which is executed using the shell, should accept MPEG frames on standard
input. The default is `mpg123 -'.
filter code
Additional filter code to restrict the packets captured, in the libpcap syntax. User filter code is evaluated as `tcp and (filter
code)'.
