Linux and Unix-Like Linux

Hello All,

A number of UNIX platforms currently bundle clients for the NIS, NIS+, and LDAP services.

I'd like to know how to discover what naming services are available.

E.g., results :

URL:
service:naming-directory:nis://192.168.1.100/eng.wiz.com
Attributes:
naming-context=eng.wiz.com
organization=flat
dynamic-updates=false
jndi-sp-available=true
master=true

URL:
service:naming-directory:nis://192.168.1.200/eng.wiz.com

Attributes:
naming-context=eng.wiz.com
organization=flat
dynamic-updates=false
jndi-sp-available=true
master=false

Thanks a lot!
LY
