tcpdump -i -n -A expression

  • -i The interface id to listen on ( run tcpdump -D to get a list of available interfaces )
  • -n Don’t convert host addresses to names (avoid dns resolution)
  • -A Print packets in ASCII, excluding link level headers. Use -X for both hex and ASCII printout.

See man pcap-filter for a full description of ‘expression’
Examples include:
tcpdump -i 11 -n -A -s 65535 port 80
tcpdump -i 11 -n -A -s 65535 dst host 10.0.0.1

Other usefull flags:
-w write packets to a file which can later be replayed with -r

I find this annoying as hell. To work around it:

Start gconf-editor
Navigate to /apps/metacity/general
Either turn off “visual_bell”, or change “visual_bell_type” from “fullscreen” to “frame_flash”

The VC2010 runtime redistributable setup needs to load msxml3. winetricks tries to download it from a location in the microsoft.com website where it is no longer available. Instead, search the web for the file “msxml3.msi” and edit winetricks to point to it, eg:


vi winetricks

Find the load_msxml3 function, and replace the download location:

From:

w_download msxml3 http://download.microsoft.com/download/8/8/8/888f34b7-4f54-4f06-8dac-fa29b19f33dd/msxml3.msi d4c2178dfb807e1a0267fce0fd06b8d51106d913

To:

w_download msxml3 ftp://ftp.uni-rostock.de/pub/tools/microsoft/XML/US/msxml3.msi
