Website shows various charactors

Some times website shows various characters instead of showing correct contents.

For solving this check the php version and check which version is compatible .

Then set the corresponding version via cpanel

i.e goto CPANEL >> php cofiguration >> enable php4 or 5

String replacement commands

Replace:
Syntax:
replace from to - filename

eg:cat test1
hai I am fine

replace hai hi -- test1

==================================

We can also use sed command for replacing the string

====================
Syntax:
sed 's/oldstring/newstring/g' filename

eg: sed 's/hai/hi/g' test1

/etc/mailips

Mailips is mainly auto-generated file and is used for outgoing SMTP interface. However, you can also manually update and manage the mailips file. Full path to the mailips is: "/etc/mailips"

The syntax is:

* Add default sending IP address

*: IP

The above line will send outgoing mail from the default (eth0) IP address. Entry begins with an asterisk (*) will sets the default sending IP (from the eth0) address for domains without their own specific entry.

* Add specific entry for the domain.

domain.tld: IP1
sub.domain.tld: IP2
addondomain.tld: IP3
other.domain.tld: IP4

Each line defines a personal outgoing server for the domain. Doing it this way, each domain can have its own outgoing IP and that way, you will be able to setup RDNS (Reverse DNS) for each IP for that domain name.

How to configure NIS (Network Information Server) Server in Redhat Linux?

To configure NIS server you have to install ypserve and yp-tools rpms on the server, and ypbind and yp-tools rpms on the client. Follow the below steps to Configure the NIS server.

1) First You need to add the NIS domain you wish to use in the /etc/sysconfig/network file
#/etc/sysconfig/network
NISDOMAIN="MYDOMAIN"

2)NIS servers also have to be NIS clients themselves, so you'll have to edit the NIS client configuration file /etc/yp.conf to list the domain's NIS server as being the server itself or localhost.
Edit your yp.conf file
# /etc/yp.conf - ypbind configuration file
ypserver 127.0.0.1

3)Start the NIS server related Daemons.
service portmap start
service yppasswdd start
service ypserv start

Ensure that the above Daemons are part of the startup

chkconfig portmap on
chkconfig yppasswdd on
chkconfig ypserv on

Client Daemons are

ypbind
portmap
Then run the below command on the server to check the services running

rpcinfo -p localhost

5) Initialize your NIS Domain
Now that you have decided on the name of the NIS domain, you'll have to use the ypinit command to create the associated authentication files for the domain. You will be prompted for the name of the NIS server.

/usr/lib/yp/ypinit -m

You can now start the ypbind and the ypxfrd daemons because the NIS domain files have been created.

service ypbind start
service ypxfrd start

6)Adding NIS users

New NIS users can be created by logging into the NIS server and creating the new user account. In this case, you'll create a user account called nisuser and give it a new password.

Once this is complete, you then have to update the NIS domain's authentication files by executing the make command in the /var/yp directory.

This procedure makes all NIS-enabled, nonprivileged accounts become automatically accessible via NIS, not just newly created ones. It also exports all the user's characteristics stored in the /etc/passwd and /etc/group files, such as the login shell, the user's group, and home directory.


useradd -g users nisuser
passwd nisuser
cd /var/yp
make

You can check to see if the user's authentication information has been updated by using the ypmatch command, which should return the user's encrypted password string.

ypmatch nisuser passwd

7) Configuring NIS client.

The authconfig or the authconfig-tui program automatically configures your NIS files after prompting you for the IP address and domain of the NIS server.

Once finished, it should create an /etc/yp.conf file that defines, amongst other things, the IP address of the NIS server for a particular domain. It also edits the /etc/sysconfig/network file to define the NIS domain to which the NIS client belongs.

n addition, the authconfig program updates the /etc/nsswitch.conf file that lists the order in which certain data sources should be searched for name lookups, such as those in DNS, LDAP, and NIS. Here you can see where NIS entries were added for the important login files.

Start the ypbind NIS client, and portmap daemons in the /etc/init.d directory and use the chkconfig command to ensure they start after the next reboot. Remember to use the rpcinfo command to ensure they are running correctly.

8) Test NIS Access to NIS server.

You can run the ypcat, ypmatch, and getent commands to make sure communication to the server is correct.

Then try logging in via ssh or telnet and test NIS .
