When trying to connect the command line interface utility in CA Spectrum 10.x and above on RHEL 7, the following error shows:
CA Spectrum CLI connect fails to connect:
connect: unable to get CLI daemon processd ticket
RHEL 7 utilizes libnss_myhostname.so.2 for name resolution. Without this package installed, CA Spectrum is unable to verify the hostname/IP and therefore fails.
Install both the 32 bit and the 64 bit version of the libnss_myhostname.so.2 package. Make sure the package version is the same for the 32 bit and 64 bit releases.
