[RHEL3] getent returns nothing if the host starts by a number 
Last modified: 2016-11-24 10:03:08 EST
Description of problem:
When running getent to retrieve its IP address we noticed that if you run it
against a system that has a hostname starting with numbers. For eg.
123host.lehman.com.. it will not return the correct IP address and exits with a
status of 2. We tested this on RHEL4 and noticed that this is fixed in this
version. Was this fixed in later versions of RHEL3 also? This is a widely used
command for shell scripts and the like. Thanks!
