Procedure for NIS
Master Server
Change the nis domain name in the master server
chypdom –B mca
or
smit chypdom
Verify tcpip is running by executing lssrc –s inetd
Verify portmap is running by executing lssrc –s portmap
(For security reason it is better to locate all nis files to /var/yp directory and change the DIR=/etc entry to DIR=/var/yp in the /var/yp/MakeFile. For merging the existing passwords execute
mrgpwd > /var/yp/passwd)
Execute mkmaster –O –E –P –U –C –B
-O Overwrites existing maps for this domain
-E Exist on errors when creating master server
-P Starts yppasswdd daemon
-U Starts ypupdated daemon
-C Starts ypbind daemon
-B Executes ypinit command, uncomment entries in rc.nfs and starts daemons
Check the yp daemons with lssrc –g yp
Slave Server
Change the nis domain name
chypdom –B mca
Edit hosts file, keep entries for loopback, this machine and of server
Execute mkslave –O –B –C mca
Client machine
Change the nis domain name
chypdom –B mca
Edit hosts file, and keep entries for loopback , this machine and of server
Execute mkclient –B mca
Check for ypbind with lssrc –s ypbind

Procedure to Build a file collection with name siju for files in /home/siju

4) copy contents of /var/sysman/sup/user.admin to siju
5) edit list file for including and omitting files in /home/siju directory
It should contains entry like the following
symlinkall
upgrade ./home/siju
omit ./home/siju/abc
omitany ./home/siju/s*
6) Add a symbolic link to siju file in lists directory to list in siju directory
ie ln -s /var/sysman/sup/siju/list /var/sysman/sup/lists/siju
7) Update /var/sysman/file.collections file with following entry
primary siju - / - / EDO power no
8) Update sup.admin file collection to reflect the changes made to file.collections
dsh -av supper update sup.admin
9) Install file collection siju in the nodes

Steps to create a Syctl application
Task :- User siju (kerberos principal siju.adm) should get the permission to start a subsystem by executing the command substart. Permission should not be given to other users.
1) Create the client application substart in /usr/bin directory of cws with following contents
if [ $# -gt 2 ]
then echo "Arguments exceed the limit"
exit 1
fi
/usr/lpp/ssp/bin/hostlist -n $1 | /usr/bin/sysctl -c - substart_proc $2
In the above script if condition will check for the number of arguments and execute procedure on
corresponding host
2) Change the mode to executable
chmod 755 /usr/bin/substart
3) Create server application substart.tcl with a procedure substart_proc with following contents
create proc substart_proc {SubSystem} AUTH {
global SCUSER
if [ aclcheck -f /etc/substart.acl $SCUSER ] {
exec /etc/substart.srv $SubSystem
return
}
}
if condition in the above example checks for kerberos user in the acl file /etc/substart.acl
If the condition is true it execute the command /etc/substart.srv with arguments passed by
substart command
4) Create the script substart.srv with following contents
startsrc -s $2
This script execute the command startsrc with the argument passed by the substart command.
5) Change the mode to executable
chmod 755 /etc/substart.srv
6) Create acl file substart.acl with the entry for user siju
#acl#
_PRINCIPAL siju.adm@CWS
7) Add the application to the sysctl by adding following line to sysctl.conf file
include /etc/substart.tcl
8) Distribute the files to all nodes
pcp -av /usr/bin/substart
pcp -av /etc/substart.tcl
pcp -av /etc/substart.srv
pcp -av /etc/substart.acl
pcp -av /etc/sysctl.conf
9) Restart the sysctld daemon to get the new information on cws and on all nodes
10) Get the kerberos ticket for user siju and execute following command
substart 3 lpd
This should start the lpd daemon on node 3
11) Try the above command with any other kerberos ticket. Result should be negative
