How reproducible:
always

Steps to Reproduce:
1. use nis and set hostname in nis hosts file to something like (3 letters):

160.129.138.133     tin     tin.structbio.vanderbilt.edu
2. set nsswitch.conf as above, try to ping tin, try traceroute, try "hostname -s"
3. turn off nscd then try all of above
  
Actual results:
when nscd is on I always get unknown hostname. when nscd is off the command succeeds

Expected results:
The command should succeed whether or not nscd is on or off.
