Server Building Chapter

The following servers are built under Ubuntu:

==================tftp Server Chapter ======================

TFTP server
1. Installation: sudo apt-get install tftpd tftp xinetd
2, modify the configuration file: sudo vim/etc/xinetd.d/tftp, write the following to the configuration file
Service TFTP
{
Socket_type = Dgram
protocol = UDP
wait = yes
user = root
Server =/usr/sbin/in.tftpd
Server_args =-s/tftpboot
Disable = no
Per_source = One
CPS = 2
flags = IPv4
}
3. Create the TFTP server root directory: sudo mkdir/tftpboot
4. Modify the permissions of the server root directory: sudo chmod 777/tftpboot/
5. Restart the server: sudo/etc/init.d/xinetd restart

Or

Apt-get Install TFTPD-HPA tftp-hpa xinetd
The TFTPD-HPA configuration file is/etc/default/tftpd-hpa
Tftp_username= "TFTP"
tftp_directory= "/tftpboot"
Tftp_address= "0.0.0.0:69"
Tftp_options= "-l-c-S"

sudo mkdir/tftpboot
chmod 777 Tftpboot-r

/etc/init.d/xinetd restart

Service TFTPD-HPA Restart

TFTP client:
First, download
1, first login: TFTP TFTP server IP address, for example: TFTP 127.0.0.1
2. Download using get command: Get file name for example: Get test.c
3. Exit: quit/q

Second, upload
1, first login: TFTP TFTP server IP address, for example: TFTP 127.0.0.1
2, re-upload: Put file name,,, for example: Put TEST.c (due to permission reasons to perform a problem)
Workaround:
1. Create the file with the same name as the file you want to upload in the TFTP server root directory: touch/tftpboot/test.c
2. Add additional Write permissions to other users of the new file: sudo chmod o+w/tftpboot/test.c
3, re-login: TFTP TFTP server IP address
4, re-upload: Put file name,,, example: Put test.c
5. Quit; quit

XP as a client:
The first thing to do is to ensure that the network is:
1. Login: TFTP 192.168.1.111 get file name,,,, for example:
TFTP 192.168.1.111 get test.c

Note turn off both sides of the firewall sudo service UFW stop

==================================nfs Server Chapter =========================================
1. Installing NFS server-side and client software
Installation Server: sudo apt-get install Portmap nfs-kernel-server
2. Configure Server for NFS: Modify/etc/exports
1), open/etc/exports file: sudo vim/etc/exports add/home/nfs * (SYNC,RW) to the document
2), create a shared directory: sudo mkdir/home/nfs
Then copy any of the files into the/home/nfs directory for easy Testing
3. Start the NFS service:
1), must first start Portmap:sudo service Portmap start
2), restart Nfs:sudo service nfs-kernel-server start

Clients must ensure that the client and server-side network are connected to each other before accessing the NFS server, and can ping the

Install client: sudo apt-get install Nfs-common
Client:
1. Querying Services for NFS: SHOWMOUNT-E NFS Server IP address
2. Create a target directory to mount to: sudo mkdir/mnt/nfs
3. Mount the shared directory of the NFS server to this machine: sudo mount-t NFS 192.168.1.111:/home/nfs//mnt/nfs
4. View the contents of the/mnt/nfs directory: Ls/mnt/nfs
5. Uninstall: sudo umount/mnt/nfs

Cat/proc/mounts will see mount information;

Firewall to shut down Oh sudo service UFW stop

========================samba Server Chapter ============================
XP as client: Linux as server side
First, install the Samba server
1. Install with command: sudo apt-get install samba
2. Configure the Samba server: sudo vim/etc/samba/smb.conf
[Global]
workgroup = MyGroup
Server string = Samba Server
log file =/var/log/samba/%m.log
max log size =
Security = User
[Homes]
comment = Home directories
browseable = no
writable = yes
[public]
Path =/home/public
Public = yes
Only guest = yes
writable = yes

3. Add Samba Users:
1), add Linux system users: sudo adduser sambauser
2), register the system user as a Samba service user:
sudo smbpasswd-a sambauser
#Added User Sambauser
sudo smbpasswd-e sambauser
#Enabled User Sambauser
4. Set up a shared directory:
1), create the shared directory you want to share: sudo mkdir/home/public

5. Start the Samba server
sudo service smbd start
Service SMBD Restart

To ensure that Windows systems are connected to the Linux system network, ping

Second, client login:
1, enter the operation in Win7: input command: \\192.168.171.129

User name: Sambauser
Password: ********

Linux as a client, XP server-side
Server-side:
1. Device sharing directory in XP system:

Client:
1. Create the target directory for the Mount:
sudo mkdir/mnt/win
2, mount the target directory;
sudo mount-o username=administrator//192.168.1.140/12/mnt/win/
3. View: Ls/mnt/win

View server Status Service SMBD status
Smbstatus

Linux:smbclient-l//localhost/sambauser
Windows: \\linux ip\\sharename

=============================ssh Server Chapter ==================================

Installation: Apt-get Install Openssh-server

Start:/etc/init.d/sshd start

Or: Service sshd restart

To see if SSH is started: netstat-a | grep ssh
