Troubleshooting the Name Service Switch

Issue the nsquery command to perform a hosts, passwd, or group lookup, as follows:
/usr/contrib/bin/nsquery lookup_type lookup_query
The lookup_type may be hosts, passwd, or group.
The lookup_query may be a host name or IP address, a user name or user ID, or a group name or group ID.

The nsquery command displays the Name Service Switch configuration that is currently in use. Then, it displays the results of the query. The following example uses nsquery to perform a lookup of the host name romney:

# /usr/contrib/bin/nsquery hosts romney
 
Using “nisplus [NOTFOUND=return] files” for the hosts policy.
 
Searching nisplus for romney
romney was NOTFOUND
 
Switch configuration: Terminates Search

As an optional third argument to nsquery, you can supply a Name Service Switch configuration in double quotes, as in the following example:

# /usr/contrib/bin/nsquery passwd 30 “files nis”
 
Using “files nis” for the passwd policy.
 
Searching /etc/passwd for 30
User name: www
User Id: 30
Group Id: 1
Gecos:
Home Directory: /
Shell:
 
Switch configuration: Terminates Search

For more information, type man 1 nsquery at the HP-UX prompt.
