Q1. CORRECT TEXT
One Domain RHCE is configured in your lab, your domain server is server1.example.com. nisuser2001, nisuser2002, nisuser2003 user are created on your server 192.168.0.254:/rhome/stationx/nisuser2001. Make sure that when NISuser login in your system
automatically mount the home directory. Home directory is separately shared on server /rhome/stationx/ where x is your Station number.
Answer and Explanation:
1. use the authconfig --nisserver=<NIS SERVER> --nisdomain=<NIS DOMAIN> --update
Example: # authconfig --nisserver=192.168.0.254 --nisdomain=RHCE --update
or system-config-authentication
2. Click on Enable NIS
3. Type the NIS Domain: RHCE
4. Type Server 192.168.0.254 then click on next and ok
5. You will get a ok message.
6. Create a Directory /rhome/stationx where x is your station number.
6. vi /etc/auto.master and write at the end of file
/rhome/stationx /etc/auto.home --timeout=60
7. vi /etc/auto.home and write
* -rw,soft,intr 192.168.0.254:/rhome/stationx/&
Note: please specify your station number in the place of x.
8. Service autofs restart
9. Login as the nisuser2001 or nisuser2002 on another terminal will be Success.
According to question, RHCE domain is already configured. We have to make a client of RHCE domain and automatically mount the home directory on your system. To make a member of domain, we use the authconfig with option or system-config-authentication command. There a are lots of authentication server i.e NIS, LDAB, SMB etc. NIS is a RPC related Services, no need to configure the DNS, we should specify the NIS server address.
Here Automount feature is available. When user tried to login, home directory will automatically mount. The automount service used the /etc/auto.master file. On /etc/auto.master file we specified the mount point the configuration file for mount point.

Q3. CORRECT TEXT
Your Local Domain is example.com. Configure the send mail server for you local LAN by following these conditions.
i. Relay the mail from 192.168.0.0/24 Network
ii. If any mail coming from cracker.org domain block all mails.
iii. user5's mail should be get by user2.
Answer and Explanation:
1. vi /etc/mail/local-host-names
example.com
2. vi /etc/mail/sendmail.mc
dnl # DEAMON_OPTIONS(`Port=smtp,Addr=127.0.0.1,Name=MTA`)dnl
3. m4 /etc/mail/sendmail.mc >/etc/mail/sendmail.cf
4. vi /etc/mail/access
192.168.0 RELAY
@cracker.org REJECT
5. service sendmail start | restart
6. chkconfig dovecot on
7. vi /etc/dovecot.conf
protocols = pop3 pop3s imap imaps
8. service dovecot start | restart
9. chkconfig dovecot on
10. vi /etc/aliases
user5: user2
11. newaliases
/etc/mail/local-host-names file contains the aliases to hostname. Mail server program reads the
/etc/mail/sendmail.cf. To change the configuration on mail server, we should edit the
/etc/mail/sendmail.mc file and should generate the sendmail.cf using m4 command.
By default sendmail server allows to connect to local host only. So we should edit the
/etc/mail/sendmail.mc file to allow connect to other hosts.
By default sendmail server will not forward mail. we should specify on /etc/mail/access to relay or to block mail coming from domain or network or individual email address.
By default dovecot service start only the imap protocol. To start pop protocol with dovecot, we should write in /etc/dovecot.conf file.
Using /etc/aliases file we can map the user name to send mail of one user to another user. To rebuild database we use the newaliases command.
