Info

3. Reboot the machine.The nscd daemon caches switch information. See the nscd(1M) man page forinformation.Some library routines do not periodically check the nsswitch.conf file to seewhether the file has been changed. You must reboot the machine to make sure thatthe daemon and those routines have the latest information in the file.DNS and Internet AccessThe nsswitch.conf file also controls DNS forwarding for clients as described in thefollowing subsections. DNS forwarding grants Internet access to clients. Forinformation on how to set DNS forwarding for NIS and NIS+, see SystemAdministration Guide: Naming and Directory Services (NIS+).IPv6 and Solaris Naming ServicesNIS, NIS+ and LDAP support storing IPv6 data, as well as using IPv6 transports forprotocol traffic. Beginning with BIND version 8.3.3, DNS on Solaris supports the use ofIPv6 transports on the client side. As of BIND version 8.4.2, DNS provides a completeclient-server solution over IPv6 networks on Solaris.The nsswitch.conf file controls search criteria for IPv6 addresses. IPv6 increases theIP address size from 32 bits to 128 bits to support more levels of addressing hierarchy.A larger address size provides a greater number of addressable nodes. For moreinformation about IPv6, its configuration and implementation, see SystemAdministration Guide: IP Services.Use the new ipnodes source for IPv6 addresses. The /etc/inet/ipnodes filestores both IPv4 and IPv6 addresses. The /etc/inet/ipnodes file uses the sameformat convention as the /etc/hosts file.IPv6 aware naming services use the new ipnodes source for its search forwarding.For instance, if LDAP is aware of IPv6 addresses, specify the following.ipnodes: ldap [NOTFOUND=return] files42 System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) • January 2005
Caution – Potential delay issues:■■ipnodes defaults to files. During the transition from IPv4 to IPv6, where allnaming services are not aware of IPv6 addresses, accept the files default.Otherwise, unnecessary delays, such as boot timing delays, might result during theresolution of addresses.An application searches all ipnodes databases for IPv4 addresses before searchingfor IPv4 addresses in the hosts databases. Before specifying ipnodes, considerthe inherent delay of searching both databases for IPv4 addresses.Ensuring Compatibility With +/- SyntaxIf +/- is used in /etc/passwd, /etc/shadow, and /etc/group files, you need tomodify the nsswitch.conf file to insure compatibility.■NIS+. To provide +/- semantics with NIS+, change the passwd and groupssources to compat. Then, add a passwd_compat: nisplus entry to thensswitch.conf file after the passwd or group entry as shown below.passwd: compatpasswd_compat: nisplusgroup: compatgroup_compat: nisplus■The above specifies that client routines obtain their network information from/etc files and NIS+ tables as indicated by the +/- entries in the files.NIS. To provide the same syntax as in the Solaris 4.x release, change the passwdand groups sources to compat.passwd: compatgroup: compatSpecifies the /etc files and NIS maps as indicated by the +/- entries in the files.Note – Users working on a client machine being served by an NIS+ server runningin NIS compatibility mode cannot run ypcat on the netgroup table. Doing sogives you results as if the table were empty even if the table has entries.Chapter 2 • The Name Service Switch (Overview) 43
