formencode/validators.py

 try:
     import DNS
     DNS.DiscoverNameServers()
+    # DNS.DiscoverNameServers() raises IOError when network isn't available
+    #  on BSD/Mac OS X
     have_dns = True
-except ImportError:
+except (IOError, ImportError):
     have_dns = False
 
 # These are only imported when needed
     This is only really useful for funny situations, like::
 
       # Any evaluates sub validators in reverse order for to_python
-      fromEmailValidator = Any( 
+      fromEmailValidator = Any(
                             Constant('unknown@localhost'),
                                Email())
 
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
