- How to set up your system as a NIS client:
-
- 1. Set your NIS domain with domainname at boottime.
-
- Example:
- if [ -r /etc/defaultdomain ] ; then
- domainname `cat /etc/defaultdomain`
- fi
- You should create the file /etc/defaultdomain with the command
- echo -n your_domain_name > /etc/defaultdomain
- Old versions of the domainname program could not deal with a \n at the
- end of /etc/defaultdomain and made it part of the domainname. This is
- fixed in this version.
-
- Please do _not_ confuse the NIS domainname (set with the domainname
- command, which uses setdomainname()) with the DNS domain name (set in
- /etc/resolv.conf). Some distributions falsely assume these are the
- same. This is wrong. Make shure the NIS domainname is the name of a
- domain served by your NIS server.
-
- 2. Find a NIS server.
- Here you have 2 possibilities. If your NIS server is in your local
- net, you can simply start ypbind. It will use broadcast to find a
- server. You can check for a NIS server with the command
- rpcinfo -b 100004 2
-
- With this release, you can enter the name of your NIS server
- to the file /etc/yp.conf. If /etc/yp.conf exists when ypbind is
- started, ypbind will search it for lines formed like
- ypserver <Name_of_ypserver>
- ypbind then tests if the given servers are up and serve the NIS
- domain. If one of the servers responds, it will use it for all further
- NIS requests, else it will fallback to broadcast. This gives you the
- possibility to use a server behind a gateway.
-
- 3. Start ypbind
- The recommended way of starting ypbind is as follows:
-
- if [ -d /var/yp ] ; then
- /usr/sbin/ypbind ; echo ypbind
- fi
-
- Be sure to set the domainname before calling ypbind and to append
- +:*:0:0:::
- to /etc/passwd, and
- +:*:0:
- to /etc/group (this is for libc-4.5.26. Since this library is buggy
- w.r.t. NIS, please use libc-4.6.27).
- ATTENTION! Do not use this entry for libc 4.6.30 and above, it will prevent
- everyone from login, since the pw_passwd entry will get overwritten with the
- star. Use a line with a single + instead.
-
-
- --- BEGIN NOTES for libc-4.6.27 ---
-
- If you are using libc-4.6.27 or above, you
- can just add a + to /etc/passwd or /etc/group to make all your NIS
- accounts available on your machine. It is possible to include oder
- exclude single users, too: just add +username or -username to
- /etc/passwd. You can even overwrite the passwd, username, directory
- and shell fields of the NIS entry, for example the entry:
-
- +swen::::NIS Hacker::/bin/tcsh
-
- would change the full name of swen to "NIS Hacker" and the shell to
- /bin/tcsh, but would leave the homedirectory to the value in the NIS
- entry.
-
- NOTE: For libc-4.6.30 and above this will work for the general entry
- +::::::
- too, so don't use
- +:*:::::
- since it will overwrite the pw_passwd field on all NIS entries and
- prevent login.
-
- libc-4.6.27 supports netgroup entries in /etc/passwd and /etc/group.
- So if you have a netgroup power_users, you can allow the members of
- this netgroup access to your machine with the line
-
- +@power_users
-
- in /etc/passwd.
-
- Note, that the rcmd() routine supports netgroup entries in
- ~/.rhosts. So if you have a netgroup named hosts, you can have remote
- access to your linux machine with the line
-
- +@hosts
-
- in ~/.rhosts (this is more secure than a single +, since this would
- allow access with your loginname from any machine in the world, and
- it is simpler than putting in every single hostname you want to
- rlogin from).
- --- END NOTES for libc-4.6.27 ---
-
- Don't forget to create the directory /var/yp. Make sure the portmapper
- is running and the NIS domainname is set before ypbind gets started.
-
- You can use NIS for your host map by adding "nis" to the order line of
- /etc/host.conf.
- Example:
-
- order hosts nis bind
- multi on
-
- This will look into /etc/hosts first, then ask nis and then the domain
- name server.
