Possible patch adapted from upstream

Description of problem:

  The "-h" option to "lp*" commands (like lpstat) is ignored if
  ServerName is set in client.conf and the port isn't specified in the
  argument to the "-h" option.


Version-Release number of selected component (if applicable):

  cups-1.6.3-26

How reproducible:

  100%

Steps to Reproduce:

  1. Set "ServerName <some-host>" in /etc/cups/client.conf
  2. run "lpstat -h <another-host> -p"

Actual results:

  The printer list from <another-host>.

Expected results:

  The printer list from <some-host>.

Additional info:

  # cat /etc/cups/client.conf

  # lpstat -h rhel73-test -p

  # lpstat -h rhel68-test -p

  # echo "ServerName rhel68-test" > /etc/cups/client.conf 
  # cat /etc/cups/client.conf
  ServerName rhel68-test

  # lpstat -h rhel73-test -p
  printer fail is idle.  enabled since Thu 09 Mar 2017 10:31:18 AM PST

  This is the same as cups.org STR #4675 which was resolved with
  https://github.com/apple/cups/commit/4b9daaf451a59d1eb1c99aac32d4e3cb19416397

  I've adapted that patch for RHEL 7.3 and attached.
  The patch fixes the issue in my testing:

  [root@sf01799390 cupsrpms]# yum update *.rpm
