FTP Setup in windows Xp

XP includes a built-in FTP service component that lets FTP clients connect to the machine and read or write files; however, this service doesn't install by default. To install the FTP service, perform the following steps:

1. Start the Control Panel Add/Remove Programs applet (go to Start, Control Panel, then click Add/Remove Programs).
2. Select Add/Remove Windows Components.
3. Select Internet Information Services (IIS), then click Details.
4. Select the File Transfer Protocol (FTP) Service check box, then click OK.
5. Click OK to close all dialog boxes.

You can use the Microsoft Management Console (MMC) Internet Information Services snap-in to configure the FTP service (go to Start, Programs, Administrative Tools, then click Internet Information Services). After the snap-in starts, expand the computer name, then expand FTP Sites. A Default FTP Site will have been added. Right-click Default FTP Site, then select Properties from the displayed context menu to set options such as Home Directory, accounts, and anonymous access. To stop the FTP service, right-click the FTP site and select Stop from the context menu; likewise, select Start from the context menu to restart the service.

ftp setup in windows 7

Please note that installation of FTP and the IIS Web server are not inter-dependent, which means you need not compulsorily install a web server in order to install an FTP server and vice-verse.


1. Go to Control Panel > Programs. Then click on "Turn Windows features On or Off".

 2. Now from the list that opens, locate the option for Internet Information Services and select FTP Server. Click on OK. Installation will take some time.

 Some additional steps for configuring the FTP sites and servers to work:


Goto control Panel

 

 

 

Get u r ftp site

 Goto Run Type u r ftp address ftp://192.168.5.45 the ftp server address contains 192.168.5.45

Configuring ip address as dhcp

How to configure DHCP address for a specific network card
In order to configure DHCP address you will need to edit the 'interfaces' file /etc/network/interfaces .

sudo vi /etc/network/interfaces

Use vi editor to edit this file, vi editor is available by default on the Ubuntu server. You can use gedit on Ubuntu desktop edition, gedit is a GNOME based editor. Inside the file delete or comment (for commenting add hash '#' just before each line) everything. You are advised to use # to comment original setting so that you can revert to old setting if necessary. Now enter the following lines and save the file. And restart the network service.

# The primary network interface use DHCP to find our address auto eth0 iface eth0 inet dhcp

sudo /etc/init.d/networking restart

Note: Replace eth0 with your own network interface card. Also learn vi commands to edit/save files - here.
How to configure Static IP address for your network card
In order set static IP address you need to edit the /etc/network/interfaces.

sudo vi /etc/network/interfaces

Replace everything with the following lines. Also change eth0 with your own network interface card. Here 192.168.1.7 is the static IP address that we want to set.

# The primary network interface auto eth0 iface eth0 inet static address 192.168.1.7 gateway 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255

After you are done with editing, save the file then you will have to restart the networking services in order to apply the new network settings. Use the following command to do so.

sudo /etc/init.d/networking restart

How to configure the DNS
DNS configuration of the Ubuntu is similar to that of other linux flavors or distributions. For static lookup you will need to add hostname and corresponding IP address to the file /etc/hosts as explained in next section.
In order to use a particular domain name server for name lookup you simply need to add its IP address to the file /etc/resolv.conf. For example if we want to use a domain name server, with IP address 192.168.1.10, for domain name lookup we will have to edit resolv.conf file. Open the file with the following command.

sudo vi /etc/resolv.conf

And then add the following lines.

search test.com nameserver 192.168.1.10

How to set or change hostname in Ubuntu
Hostname can be very easily manipulated in Ubuntu. You can directly query, or set the hostname with the hostname command.
To see the current hostname use the following command.

sudo /bin/hostname

To change the hostname use the command given below, change the newhostname with your own hostname.

sudo /bin/hostname newhostname

When your system reboots it will automatically read the hostname from the file /etc/hostname.
How to setup second IP address or virtual IP address in Ubuntu
Sometimes you may need to setup a second IP address for your computer, specially if you are a server administrator. To do this you need to edit the /etc/network/interfaces file.

sudo vi /etc/network/interfaces

Add the following lines in the file. Change according to your IP address settings.

auto eth0:1 iface eth0:1 inet static address 192.168.1.60 netmask 255.255.255.0 network x.x.x.x broadcast x.x.x.x gateway x.x.x.x

You need to enter correctly all the network details such as address, netmask, network, broadcast and gateway values. Once you have completed this, save this file and then restart networking services using the following command so that new settings are applied.
sudo /etc/init.d/networking restart

NFS Configuration

Edit the file /etc/exports

 

/sharepath *(rw,sync)

Ex:/home *(rw,sync) 

restart the nfs service 

[root@usha ~]# service nfs restart
    Shutting down NFS mountd:                                  [  OK  ]
    Shutting down NFS daemon:                                  [  OK  ]
 Shutting down NFS quotas:                                  [  OK  ]
 Shutting down NFS services:                                [  OK  ]
Starting NFS services:                                     [  OK  ]
Starting NFS quotas:                                       [  OK  ]
Starting NFS daemon:                                       [  OK  ]
Starting NFS mountd:                                       [  OK  ]

Mount nfs in another System

mount -t nfs 192.168.2 .85:/home /mnt

samba configuration

create an user add the user to the samba user

[root@usha ~]# smbpasswd -a dapuser
New SMB password:
Retype new SMB password:
Added user dapuser.

Edit the file /etc/samba/smb.conf


 path = /usr/somewhere/shared
valid users =dapuser
public = no
readable=yes
writable = yes
printable = no
browseable=tes

path is that which folder u want to share

Logon from the Windows System

Goto -> start -> Run type \\192.168.5.245

the samba server contains 192.168.5.245 as the ip address

Username  dapuser
password  dap@123

mount the shared content to u r system




FROM LINUX

Goto Places->Connect to server

 Windows share enter  server ip address  and click connect.Enter the username and passwd get the content of samba server

ldap Configuration

check the below packages are available:

[root@usha ~]# rpm -qa | grep openldap-servers
openldap-servers-2.3.27-5

compat-openldap.i386 0:2.1.30-6.4E

openldap-servers.i386 0:2.2.13-6.4E
openldap-servers-sql.i386 0:2.2.13-6.4E




if packages not available install from cd

yum install *openldap* -y

on the ldap service
[root@usha ~]# chkconfig --levels 235 ldap on
