Yum Update doesn't work (formerly NFS problem -- just doesn't work)

I get the same thing.  I tried configuring to use a mirror by adding some
new repos to my yum.repos.d directory, and got the same error from that
repository.  

Is this the right way to configure using a mirror?

/etc/yum.repos.d/wisc-base.repo:
[wisconsinbase]
name=Wisconsin Mirror
baseurl=ftp://mirror.services.wisc.edu/pub/linux/distributions/yellowdog/yum
/5.0/base/
enabled=1

Then I added wisc-extras.repo and wisc-update.repo the same way. 

I got the URL to the repo out of the MIRRORS file off of
ftp.yellowdoglinux.com.  Here's the head of the file:
