All,

I recently installed TileCache 2.10 as a CGI in a RHEL environment and
am receiving the following error when I try to access:
http://myhost/tilecache/tilecache.cgi?LAYERS=basic&SERVICE=WMS%20&VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&BBOX=-180,-90,0,90%20&WIDTH=256&HEIGHT=256

An error occurred: <urlopen error (-3, 'Temporary failure in name resolution')>
  File "/var/www/tilecache/TileCache/Service.py", line 323, in cgiHandler
    format, image = service.dispatchRequest( params, path_info,
req_method, host )
  File "/var/www/tilecache/TileCache/Service.py", line 208, in dispatchRequest
    return self.renderTile(tile, params.has_key('FORCE'))
  File "/var/www/tilecache/TileCache/Service.py", line 138, in renderTile
    data = layer.render(tile, force=force)
  File "/var/www/tilecache/TileCache/Layer.py", line 443, in render
    return self.renderTile(tile)
  File "/var/www/tilecache/TileCache/Layers/WMS.py", line 29, in renderTile
    tile.data, response = wms.fetch()
  File "/var/www/tilecache/TileCache/Client.py", line 58, in fetch
    response = self.client.open(urlrequest)
  File "/usr/lib64/python2.4/urllib2.py", line 358, in open
    response = self._open(req, data)
  File "/usr/lib64/python2.4/urllib2.py", line 376, in _open
    '_open', req)
  File "/usr/lib64/python2.4/urllib2.py", line 337, in _call_chain
    result = func(*args)
  File "/usr/lib64/python2.4/urllib2.py", line 1032, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib64/python2.4/urllib2.py", line 1006, in do_open
    raise URLError(err)

When I access http://myhost/tilecache/index.html I see map controls
and a bunch of tiles showing broken link icons.

I'm using the default tilecache.cfg, and I can't find any immediately
obvious permission problems to explain the issue.  Any ideas?

Thanks,
John
