       xtraceroute - graphical (X11) traceroute

       xtraceroute [options] [hostname]

       This  manual page briefly documents the xtraceroute, command.  This manual page was origi-
       nally written for the Debian GNU/Linux distribution because the original program does  not
       have  a manual page.  Since then the author has gotten his act together and keeps it up to

       xtraceroute is a graphical version of the traceroute program, which traces the route  your
       IP packets travel to their destination.

       On the display:

       * Green dots have good location information that came from LOC fields in the DNS, which is
       the best data out there.

       * Orange ones has been guessed from the sites' suffix.

       * Yellow ones got resolved via a database of city names and "known" routers.  That data is
       old and inaccurate and it's not getting any younger.

       * Red ones are completely unknown.

       * You can select dots by clicking on them both on the globe and in the list.

       *  Pressing  and holding the left mouse button and moving the mouse will rotate the globe.
       Using the middle mouse button will move it, and the right mouse button will zoom it  (only
       vertical movement counts). You can generally get the view you want this way.

       hostname is the name (or IP address) of the host you are interested in.

       The  program follow the usual GNU command line syntax, with long options starting with two
       dashes (`-').

	      Show version number

       -h, --help
	      Display a brief help text.

       -T, --texture texture-name
	      Use a custom texture (map). It can be any kind of file  that  gdk_pixbuf	can  load
	      (which  is  most	reasonable  formats).	There  are  a few really good textures on
	      http://www.radcyberzine.com/xglobe/ (Meant for use with Xglobe,  but  they'll  work
	      fine here as well.)

       --LOD number
	      Set  the level-of-detail for the sphere.	(The default is 3, 0-4 are realistic val-

       --stdin, -
	      Makes the program read data from stdin instead  of  calling  traceroute(8)  (Mainly
	      useful for debugging)

       xtraceroute  tries  hard  to  guess  the location of machines, but it is just software, it
       doesn't know everything, and it makes mistakes.

       The yellow dots has been guessed by looking at the top level domain (TLD) of the hostname.
       This  works  fairly well for most countries, but there's a few exceptions where some small
       countries (like Niue (.nu) and Tuvalu (.tv)) will let anyone  register  domains	in  their
       space  for  a  fee. I don't care, If it says .nu and it hasn't got a LOC record, it'll get
       plotted in Niue.  Also, very few US sites actually use the .us TLD.

       If it finds a very high-latency link, it will assume it it a satellite  hop  and  plot  it
       accordingly.  If  you have some other kind of slow link, like PPP over something slow or a
       really busy router, it might show up as a satellite hop as well.

	      System-wide hosts file (optional)

	      System-wide networks file (optional)

       The two files above are filled in by hand, following  the  model  of  /usr/lib/xtraceroute
       *.cache files.

	      Your personal networks file

	      Your personal base of regular expressions

       These three personal files are typically filled in via the Database menu.

LOC data
       The  Correct Way to tell the geographical location of a host on the internet is to ask the
       DNS. The way to do that is described in RFC1876, which defines the LOC (for location)  RR.
       It's  not  exactly  widely used, but you see it every now and then. Hopefully this program
       can help change that.

       How to get LOC data for your site into the DNS:

       Ask your local sysadmin that maintain your nameserver to read the RFC.  It's a fairly easy
       read  as  RFCs  go, but it might help if you find out the location of your site in advance
       using, say, a GPS or a site like http://www.mapblast.com. Sysadmins are busy people.

       When xtraceroute tries to resolve a hostname it will try the proper name first,	and  then
       higher  domains.  For  example  if  our hostname is "apa.bepa.cepa.com", it will try that,
       "bepa.cepa.com" and "cepa.com".	(But not just "com")

       This means that if you're a big site and it's hard to persuade the admins to add  individ-
       ual LOC entries for all machines, you can try getting them to add one or two for the whole
