== Super User Account ==
 +
There is no password for the super user account "root". You can simply type "su -" to switch to super user account in order to perform the following task:
 +
* yum update
 +
* yum install package-name
 +
* switch SELinux mode
 +
* list, flush, add, delete firewall rule using the iptables command
 +
* start/stop network service
 +
* add/remove/modify user accounts
 +
* add/remove software package
 +
* other administrative tasks
 +
* reading system log files
 +
 +
=== Monitoring System Main Log File ===
 +
Most system daemons write log messages to the main system log file at /var/log/messages. As a system administrator, you can view any new log messages written to the file in real time using the following command line in a terminal window:
 +
 +
[root@localhost ~]# tail -f /var/log/messages
 +

 +
 +
The above messages were generated when a user plugged in an USB Flash drive to the system. In this example, the system assgined the device name [sdc] to identify the Flash drive.
 +

 +
 +
== SELinux Configuration ==
 +
Security Enhence Linux is enabled by default.
 +
[root@localhost ~]# sestatus
 +
SELinux status:                enabled
 +
SELinuxfs mount:                /selinux
 +
Current mode:                  enforcing
 +
Mode from config file:          enforcing
 +
Policy version:                24
 +
Policy from config file:        targeted
 +
[root@localhost ~]#
 +
 +
To Keep SELinux running but ask it not to enforce the Security Policy, do the following:
 +
[root@localhost ~]# setenforce 0
 +
[root@localhost ~]# sestatus
 +
SELinux status:                enabled
 +
SELinuxfs mount:                /selinux
 +
Current mode:                  permissive
 +
Mode from config file:          enforcing
 +
Policy version:                24
 +
Policy from config file:        targeted
 +
 +
It is not recommended to turn off SELinux. If you encounter some SELinux policy issues and can not get it resolve, then you should set it to permissive mode.
 +
 +
To switch SELinux from "permissive" mode to "enforcing" mode, do the following:
 +
[root@localhost ~]# setenforce 1
 +
[root@localhost ~]# sestatus
 +
SELinux status:                enabled
 +
SELinuxfs mount:                /selinux
 +
Current mode:                  enforcing
 +
Mode from config file:          enforcing
 +
Policy version:                24
 +
Policy from config file:        targeted
 +
 +
== Firewall Configuration ==
 +
Fedora distribution use "netfilter" kernel module for building a Stateful Packet Filtering firewall. Firewall is enable on Fedora Live DVD by default.
 +
=== Default Firewall Setting ===
 +
The default firewall configuration:
 +
   
 +
[root@localhost ~]# iptables -L --line-number
 +
Chain INPUT (policy ACCEPT)
 +
num  target    prot opt source              destination       
 +
1    ACCEPT    all  --  anywhere            anywhere            state RELATED,ESTABLISHED
 +
2    ACCEPT    icmp --  anywhere            anywhere           
 +
3    ACCEPT    all  --  anywhere            anywhere           
 +
4    ACCEPT    udp  --  anywhere            224.0.0.251        state NEW udp dpt:mdns
 +
5    REJECT    all  --  anywhere            anywhere            reject-with icmp-host-prohibited
 +
 +
Chain FORWARD (policy ACCEPT)
 +
num  target    prot opt source              destination       
 +
1    REJECT    all  --  anywhere            anywhere            reject-with icmp-host-prohibited
 +
 +
Chain OUTPUT (policy ACCEPT)
 +
num  target    prot opt source              destination         
 +
 +
* Incoming packets will be filtered based on firewall rules for the INPUT chain (Chain num 1 to 5)
 +
** Rule number 1 allows any packets which are related to any packets went out before
 +
** Rule number 2 allows any icmp packets, including echo-request and echo-reply packet (used by the ping command)
 +
** Rule number 3 allows packets coming from the loop back network interface (lo), need to "-v" to show the interface name.
 +
** Rule number 4 allows packets go to IP address 224.0.0.251 port 5353
 +
** Rule number 5 blocks all other incoming packets
 +
 +
* No packet will be forwarded.
 +
 +
* All outgoing packets are allowed.
 +
 +
=== Flush out firewall rules in the Filter table ===
 +
To turn off the blocking of Incoming packet, do the following:
 +
[root@localhost ~]# iptables -F
 +
[root@localhost ~]# iptables -L
 +
Chain INPUT (policy ACCEPT)
 +
target    prot opt source              destination       
 +
 +
Chain FORWARD (policy ACCEPT)
 +
target    prot opt source              destination         
 +
 +
Chain OUTPUT (policy ACCEPT)
 +
target    prot opt source              destination
 +
 +
The "iptables -F" command "flushes" out all the firewall rules in the filter table. The "iptables -L" displays the updated firewall rules in the filter table (none left after the iptables -F command).
 +
 +
=== Restore default firewall rules to the Filter table ===
 +
To restore the default firewall, do the following:
 +
[root@localhost ~]# service iptables restart
 +
iptables: Flushing firewall rules:                        [  OK  ]
 +
iptables: Setting chains to policy ACCEPT: raw mangle nat f[  OK  ]
 +

1017

Super User Account

There is no password for the super user account "root". You can simply type "su -" to switch to super user account in order to perform the following task:

  • yum update
  • yum install package-name
  • switch SELinux mode
  • list, flush, add, delete firewall rule using the iptables command
  • start/stop network service
  • add/remove/modify user accounts
  • add/remove software package
  • other administrative tasks
  • reading system log files

Monitoring System Main Log File

Most system daemons write log messages to the main system log file at /var/log/messages. As a system administrator, you can view any new log messages written to the file in real time using the following command line in a terminal window: 

[root@localhost ~]# tail -f /var/log/messages

SELinux Configuration

Security Enhence Linux is enabled by default. 

[root@localhost ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   enforcing
Mode from config file:          enforcing
Policy version:                 24
Policy from config file:        targeted
[root@localhost ~]#

To Keep SELinux running but ask it not to enforce the Security Policy, do the following: 

[root@localhost ~]# setenforce 0
[root@localhost ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   permissive
Mode from config file:          enforcing
Policy version:                 24
Policy from config file:        targeted

It is not recommended to turn off SELinux. If you encounter some SELinux policy issues and can not get it resolve, then you should set it to permissive mode.

To switch SELinux from "permissive" mode to "enforcing" mode, do the following: 

[root@localhost ~]# setenforce 1
[root@localhost ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   enforcing
Mode from config file:          enforcing
Policy version:                 24
Policy from config file:        targeted

Firewall Configuration

Fedora distribution use "netfilter" kernel module for building a Stateful Packet Filtering firewall. Firewall is enable on Fedora Live DVD by default.

Default Firewall Setting

The default firewall configuration: 

[root@localhost ~]# iptables -L --line-number
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination         
1    ACCEPT     all  --  anywhere             anywhere            state RELATED,ESTABLISHED 
2    ACCEPT     icmp --  anywhere             anywhere            
3    ACCEPT     all  --  anywhere             anywhere            
4    ACCEPT     udp  --  anywhere             224.0.0.251         state NEW udp dpt:mdns 
5    REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited 

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination         
1    REJECT     all  --  anywhere             anywhere            reject-with icmp-host-prohibited 

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination
  • Incoming packets will be filtered based on firewall rules for the INPUT chain (Chain num 1 to 5)
    • Rule number 1 allows any packets which are related to any packets went out before
    • Rule number 2 allows any icmp packets, including echo-request and echo-reply packet (used by the ping command)
    • Rule number 3 allows packets coming from the loop back network interface (lo), need to "-v" to show the interface name.
    • Rule number 4 allows packets go to IP address 224.0.0.251 port 5353
    • Rule number 5 blocks all other incoming packets
  • No packet will be forwarded.
  • All outgoing packets are allowed.

Flush out firewall rules in the Filter table

To turn off the blocking of Incoming packet, do the following: 

[root@localhost ~]# iptables -F
[root@localhost ~]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination          

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

The "iptables -F" command "flushes" out all the firewall rules in the filter table. The "iptables -L" displays the updated firewall rules in the filter table (none left after the iptables -F command).

Restore default firewall rules to the Filter table

To restore the default firewall, do the following: 

[root@localhost ~]# service iptables restart
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: raw mangle nat f[  OK  ]
iptables: Unloading modules:                               [  OK  ]
iptables: Applying firewall rules:
