[Tilecache] TileCache configuration Problem?

[R. Ortner]

Hi, i tried to set up tilecache running under cgi.

i copied the tilecache files in:
    /var/www/htdocs/tc

made a folder for the cache files:
    /var/www/htdocs/tilecache

made the entry in the apache httpd.conf file:
    <Directory /var/www/htdocs/tc>
             AddHandler cgi-script .cgi
             Options +ExecCGI
    </Directory>

and changed the cache dir in the tilecache.cfg file:
    [cache]
    type=DiskCache
    base=/var/www/htdocs/tilecache/

rest of the tilecache.cfg is unchagned.


Now i tried to start the index.html from the tilecache directory:
    http://172.21.18.45/tc/index.html

 -> the restults are pinkt tiles after a long time of wating!


When i try to get a tile with the wms request from the readme with:
    
http://172.21.18.45/tc/tilecache.cgi?LAYERS=basic&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&BBOX=-180,-90,0,90&WIDTH=256&HEIGHT=256

    -> i get the following error message:

An error occurred: <urlopen error (110, 'Connection timed out')>
  File "/var/www/htdocs/tc/TileCache/Service.py", line 525, in cgiHandler
    format, image = service.dispatchRequest( params, path_info, req_method,
host )
  File "/var/www/htdocs/tc/TileCache/Service.py", line 443, in
dispatchRequest
    return self.renderTile(tile, params.has_key('FORCE'))
  File "/var/www/htdocs/tc/TileCache/Service.py", line 401, in renderTile
    data = layer.render(tile)
  File "/var/www/htdocs/tc/TileCache/Layer.py", line 253, in render
    return self.renderTile(tile)
  File "/var/www/htdocs/tc/TileCache/Layer.py", line 297, in renderTile
    tile.data, response = wms.fetch()
  File "/var/www/htdocs/tc/TileCache/Client.py", line 45, in fetch
    response = self.client.open(urlrequest)
  File "/usr/lib/python2.4/urllib2.py", line 358, in open
    response = self._open(req, data)
  File "/usr/lib/python2.4/urllib2.py", line 376, in _open
    '_open', req)
  File "/usr/lib/python2.4/urllib2.py", line 337, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.4/urllib2.py", line 1021, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib/python2.4/urllib2.py", line 996, in do_open
    raise URLError(err)



the permissions for the folders and files are all set to 755 or 777.

Maybe anyone have an idea whats wrong? I thought i followed the instructions
correctly but oviously i missed something!
