[sebastian serrano <sserrano@speedy.com.ar>]

I have install the kernel image 2.6.2-1-686
And now i can't access to pages that i now that they are working and 
others are working
right.
for example www.google.com.ar works great but www.uolsinectis.com.ar not 
(and i now
it's working), mozilla says to my "the document contains no data"


if try to download with wget says:
# wget www.uolsinectis.com.ar
