Q11. CORRECT TEXT
Configure to deny the pop and imap connection from outside local LAN as well as station20.example.com.
Answer and Explanation:
1. vi /etc/hosts.deny
dovecot:ALL EXCEPT .example.com EXCEPT station20.example.com
We can secure the services using tcp_wrappers. There are main two files, /etc/hosts.allow and /etc/hosts.deny.
There will be three stage access checking
-Is access explicitly permitted? Means permitted from /etc/hosts.allow?
- Otherwise, Is access explicitly denied? Means denied from /etc/hosts.deny?
- Otherwise, by default permit access if neither condition matched.
To deny the services we can configure /etc/hosts.deny file using ALL and EXCEPT operation.
Pattern of /etc/hosts.allow and /etc/hosts.deny file is:
Demon_list:client_list:options
In Client list can be either domain name or IP address.

Q13. CORRECT TEXT
You have a directory /local. You want to make available that directory to all the members of example.com and trusted.cracker.org. But directory should available in read and write to all the members of example.com domain and read only to cracker.org domain.
Answer and Explanation:
1. vi /etc/exports
/local *.example.com(rw,sync) trusted.cracker.org(ro,sync)
Check the SELinux Context, should be like this:
-rw-r--r-- root root system_u:object_r:exports_t /etc/exports
Use the restorecon -R /etc command to restore the selinux context of the file.
2. service nfs start | restart
3. service portmap start | restart
4. chkconfig nfs on
5. chkconfig portmap on
In Linux to share the data we use the /etc/exports file. Pattern is:
Path client(permission)
Shared Directory Path, Client can be single host or domain name or ip address. Permission should specify without space with client lists in parentheses. NFS is RPC service so portmapper service should restart after starting the nfs service. We can specify multiple clients' list separating by space with different shared option.
Q14. CORRECT TEXT
You are giving the RHCE exam. Now you should boot your System properly. When you started your System, You got one message that.
INIT Entering runlevel 9
INIT: no more processes left in this runlevel

Except for a normal boot of Linux, single-user mode is the most commonly used option. This is the system maintenance mode for experienced Linux administrators. It allows you to perform clean backups and restores to any partitions as needed from local hardware. It also allows you to run administration commands, recover or repair password and shadow password files, run filesystem checks, and so forth.
3. vi /etc/inittab and Write
id:runlevel:initdefault:
Standard Runlevels in RedHat Enterprise Linux

account required /lib/security/pam_access.so
/etc/security/access.conf file helps to allow or deny login to users on the basis of origin.
Syntax of /etc/security/access.conf
permission : users : origins
The first field should be a "+" (access granted) or "-" (access denied) character.
The second field should be a list of one or more login names, group names, or ALL (always matches). A pattern of the form user@host is matched when the login name matches the "user" part, and when the "host" part matches the local machine name.
The third field should be a list of one or more tty names (for non-networked logins), host names, domain names (begin with "."), host addresses, internet network numbers (end with "."), ALL (always matches) or LOCAL (matches any string that does not contain a "." character).
In our example denied to john user to login locally.

Your Local Domain is example.com. Configure the send mail server for you local LAN. As well as enable the pop and pop secured protocol.
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

5. service sendmail start | restart
6. chkconfig dovecot on
7. vi /etc/dovecot.conf
protocols = pop3 pop3s
8. service dovecot start | restart
9. chkconfig dovecot on
/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.
Q20. CORRECT TEXT

Answer and Explanation:
Slave DNS is the backup of master DNS. Automatically within a certain time slave DNS synchronizes with the Master DNS server.

zone "example.com" IN {
type slave;
masters { 192.100.0.254; };
file "example.com.zone";
};
named-checkconf command checks the syntax for /var/named/chroot/etc/named.conf file.service named start | restart
