[Zope] DNS lookup problem with urllib in external methods

Have anyone seen this strange behavior. urllib.urlget("http://some-url") works perfectly well from a regular python script. The the same line will produce an Error Type: IOError Error Value: [Errno socket error] host not found when called from an external zope method. However urllib.urlget("http://some-ipnumber") will work fine in that same external method. Any ideas? Does zope use some special dns settings? oivvio -- oivvio polite cell +46 (0)709 30 40 30 / phone +46 (0)8 669 64 18 / fax +46 (0)8 84 00 18 varvsgatan 10A / s-117 29 stockholm / sweden
