Network Printer On Windows Machine

NETWOK PRINTER INSTALLATION ON WINDOWS

Requirement:
1. XP/2000/2003 Operating System (I have made XP machine as Network Printer)
2. Printer (I Configured On HP Officejet 5600 Series)
3. Printer Drivers (Need to Install On Connecting Printer Machine)
4. IP Address In same range (Connect All Machines & Printer In Same LAN with same IP range)

Note: All Setup should be happen in Administrator account only (Connected Printer machine & Client Machine also)
Printer Connected IP Address: 192.168.1.11

Steps:

1.Install Printer Drivers on Connected Printer Machine in administrator account
2.Connect 'n' no of system on same network (LAN)
3.Assign IP address and gateway in same range
4.Go to Start→control panel & click on Printer & Faxes (Connected Printer Machine)
5.Right click on Printer & Faxes → Share → Share this Printer → Apply → OK .
6.Go to client machine and check connectivity with Installed Printer system with ping 192.168.1.11.
7. Go to Run → \\192.168.1.11 ( Printer Installed IP Address) → Printer & Faxes → Open → right click on shared printer → connect. (In Client Machine)
8.Try to give test Print.
9.You will get print out by configured printer machine (192.168.1.11).

Note: In case in client machine limited users need to use network printer then once you have to follow same procedure what you have done in admin account (Run → \\192.168.1.11 ( Printer Installed IP Address) → Printer & Faxes → Open → right click on shared printer → connect).

NIS CONFIGURATION ON REDHAT LINUX

NIS SERVER CONFIGURATION (NETWORK INFORMATION SERVICE)

SERVER CONFIGURATION

Note: While NIS configuring time disable the firewall/iptables service (service iptables stop), later will configure firewall setting with NIS server.

Requirement:

1. Portmap (Default Installed)
2. Yp-tools (Default Installed)
3. Ypbind (Need To Install)
4. Ypserv (Need To Install)

Install Required Packages/tools:
[root@sandeep~]# rpm -i ypserv-2.13-5.x86_64.rpm (Install ypserv package)
[root@sandeep~]# rpm -i ypbind-1.17.2-3.x86_64.rpm (Install ypbind package)

Check Required Packages are Installed On NIS Server:
[root@sandeep ~]# rpm -qa portmap
portmap-4.0-63
[root@sandeep ~]# rpm -qa yp-tools
yp-tools-2.8-7
[root@sandeep ~]# rpm -qa ypbind
ypbind-1.17.2-3
[root@sandeep ~]# rpm -qa ypserv
ypserv-2.13-5
[root@sandeep ~]#

Edit Your /etc/sysconfig/network File
(You need to add the NIS domain you wish to use in the /etc/sysconfig/network file. For the SANDEEP, call the domain SANDEEP-NIS-SERVER.)

[root@sandeep ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=sandeep
NISDOMAIN="SANDEEP-NIS-SERVER"

Edit Your /etc/yp.conf File
[root@sandeep ~]# vi /etc/yp.conf
# ypserver 192.168.1.11

Start the Key NIS server related daemons
Start the necessary NIS daemons in the /etc/init.d directory and use the chkconfig command to ensure they start after the next reboot
[root@sandeep]# service portmap start
Starting portmapper: [ OK ]
[root@sandeep]# service yppasswdd start
Starting YP passwd service: [ OK ]
[root@sandeep]# service ypserv start

Initialize Your NIS domain (Add Clients on NIS network)
[root@sandeep ~]# /usr/lib64/yp/ypinit -m

At this point, we have to construct a list of the hosts which will run NIS
servers. sandeep is in the list of NIS server hosts. Please continue to add
the names for the other hosts, one per line. When you are done with the
list, type a .
next host to add: sandeep
next host to add: sandeep1
next host to add: sandeep2
next host to add:

(Press Y and)

The current list of NIS servers looks like this:

sandeep
sandeep1
sandeep2

Is this correct? [y/n: y] y
We need a few minutes to build the databases...

Adding New NIS Users
[root@sandeep]# useradd -g users nisuser
[root@sandeep]# passwd nisuser

[root@sandeep yp]#

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.
[root@sandeep yp]# ypmatch nisuser passwd
nisuser:$1$d6E2i79Q$wp3Eo0Qw9nFD/::504:100::/home/nisuser:/bin/bash
[root@sandeep yp]

You can also use the getent command, which has similar syntax. Unlike ypmatch, getent doesn't provide an encrypted password when run on an NIS server, it just provides the user's entry in the /etc/passwd file. On a NIS client, the results are identical with both showing the encrypted password.
[root@sandeep yp]# getent passwd nisuser
nisuser:x:504:100::/home/nisuser:/bin/bash
[root@sandeep yp]#

FIREWALL CONFIGURATION WITH NIS SERVER:

Edit /etc/sysconfig/iptables file for Enabling NIS (ypbind/portmap port – 111), Enable port no 111 for TCP as well as UDP. (Two lines given bellow just add in iptables file and save & exit)

[root@sandeep ~]# cd /etc/sysconfig/
[root@sandeep sysconfig]# vi iptables

-A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 111 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --dport 111 -j ACCEPT

:wq Enter (Save iptables file and exit)

Restart iptables service:
(Check service should not be [Fail],everything should be [OK])

[root@sandeep ~]# service iptables restart
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
[root@sandeep ~]#

Restart ypbind service:
(Once restart ypbind service, check whether it will restart or not after enabling 111 port & starting firewall)

[root@sandeep ~]# service ypbind restart
Shutting down NIS services: [ OK ]
Binding to the NIS domain: [ OK ]
Listening for an NIS domain server.
[root@sandeep ~]#


CLIENT CONFIGURATION:

Note: While NIS Client configuring time disable the firewall/iptables service (service iptables stop), later will configure firewall setting with NIS server.

Run authconfig

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
[root@sandeep2 ~]# authconfig-tui
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.

Requirement Of Package for Client Machine:
1. Portmap
2. Yp-tools
3. Ypbind

[root@sandeep2 etc]# vi yp.conf
domain SANDEEP-NIS-SERVER server 192.168.1.11
[root@sandeep2 etc]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=sandeep2
NISDOMAIN=SANDEEP-NIS-SERVER

[root@sandeep2 etc]# cat nsswitch.conf
passwd: files nis
shadow: files nis
group: files nis

Start The NIS Client Related Daemons
[root@sandeep2 etc]# service portmap start
Starting portmap: [ OK ]
[root@sandeep2 etc]# service ypbind start
Binding to the NIS domain: [ OK ]
Listening for an NIS domain server.
[root@sandeep2 etc]# chkconfig ypbind on
[root@sandeep2 etc]# chkconfig portmap on
[root@sandeep2 etc]#

Note:
Remember to use the rpcinfo -p localhost command to make sure they all started correctly.

[root@sandeep2 etc]# rpcinfo -p

Verify Name Resolution

As the configuration examples refer to the NIS client and server by their hostnames, you'll have to make sure the names resolve correctly to IP addresses. This can be configured either in DNS, when the hosts reside in the same domain, or more simply by editing the /etc/hosts file on both Linux boxes.

[root@sandeep2 etc]# vi hosts [Enter server IP and Machine Name]
# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.1.9 sandeep1 sandeep1
192.168.1.10 sandeep2 sandeep2 192.168.1.10
192.168.1.11 sandeep sandeep

Logging In Via SSH
Click On SSH Secure Shell → Quick Connect → Host Name (Give Client IP Address) 192.168.1.10 → User Name (Give Created nisuser in server) nisuser → Connect → Password (nisuser123) → you will get bash screen [Last login: Wed Feb 10 12:59:46 2010 from 192.168.1.212
-bash-3.00$
]

FIREWALL CONFIGURATION WITH NIS CLIENT:
Edit /etc/sysconfig/iptables file for Enabling NIS (ypbind/portmap port – 111), Enable port no 111 for TCP as well as UDP. (Two lines given bellow just add in iptables file and save & exit)

[root@sandeep2 ~]# cd /etc/sysconfig/
[root@sandeep2 sysconfig]# vi iptables

-A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 111 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --dport 111 -j ACCEPT

:wq Enter (Save iptables file and exit)

Restart iptables service:
(Check service should not be [Fail],everything should be [OK])

[root@sandeep2 ~]# service iptables restart
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
[root@sandeep2 ~]#

Restart ypbind service:
(Once restart ypbind service, check whether it will restart or not after enabling 111 port & starting firewall)

[root@sandeep2 ~]# service ypbind restart
Shutting down NIS services: [ OK ]
Binding to the NIS domain: [ OK ]
Listening for an NIS domain server.
[root@sandeep2 ~]#

Troubleshoot with NIS server & Client:
Note: If firewall is running in Server then client ypbind will not start, so 1st take care of firewall, stop firewall and restart ypbind in server, then restart firewall & ypbind in client machine then restart firewall in server, then you wont get any kind of error. [if you have started firewall in server machine then trying to start ypbind with firewall in client side you wont get OK result, you will be get only Fail result after long time so keep in mind that 1st restart ypbind in server → restart firewall & ypbind in client machine → then restart firewall in server]

FTP Configuration On REDHAT LINUX-4

REDHAT LINUX-4 FTP CONFIGURATION:

RHEL server comes with vsftpd which is the Very Secure File
Transfer Protocol (FTP) daemon. The server can be launched
via a xinetd or as standalone mode, in which case vsftpd
itself will listen on the network port 21.

STEPS:

Install vsftpd rpm by CD driver (vsftpd application is available in redhat OS CD)
Install Vsftpd:
root ]# /media
media]# ls -l
media] cp vsftpd-2.0.1-5.EL4.3.x86_64.rpm /var/
media]# exit
root ]# cd /var/
var]# ls -ltr
var]# rpm -i vsftpd-2.0.1-5.EL4.3.x86_64.rpm (rpm -i vsftpd-2.0.1-5.EL4.3.x86_64.rpm –nodeps) [Or else we can also use yum to install instead of rpm)
root ]#

Turn on Vsftpd Service:
root ]# service vsftpd start (For Stop @ root ]# service vsftpd stop/status)

Open FTP Port
root ]# cd /etc/sysconfig/
root ]# ls -l
root ]# vi iptables
(Append following line to open ftp port 21 before REJECT line:)
Ports: 20 for data transmission & 21 for ftp controller

root ]# -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 20 -j ACCEPT
root ]# -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT
root ]# (press Esc) :wq

Restart Iptables/Firewall
root ]# service iptables start

Edit FTP Conf file:-
root ]# vi /etc/vsftpd/vsftpd.conf
(Add this line at the end of the file)
userlist_deny=NO (This option use for ftp users, if you give NO then you have to add, needed users in /etc/vsftd.user_list or else if you give YES then all user have ftp permissions means any normal users can access ftp server)

Edit user_list file,
root ]# vi /etc/vsftpd.user_list
ftp1

Restart FTP services
/etc/init.d/vsftpd start/restart
chkconfig vsftpd on ( for permanent on )

To Disable Root Directory

[root@server vsftpd]# vi vsftpd.conf
chroot_list_enable=YES ----> Remove #
chroot_list_file=/etc/vsftpd/chroot_list ----> Remove # & Give path of chroot_list file
[Create one file in /etc/vsftpd/chroot_list & Put users name, which users needed access of ftp]

Note:
We can transfer the data from Linux to Windows by using FTP (by using win XP machine), If we require to transfer data from Window to Linux (by using Linux machine) then we have to enable FTP port (21) in windows machine.
