WS_FTP Server Overviews

Unrivalled Security. Powerful Administrator Control.

How secure is your data?

IT departments today are faced with the challenge of managing file transfers in an environment of data breaches, regulatory compliance, corporate governance requirements, and more. To overcome these challenges, server administrators need to make company data easily available to employees, data that is often highly sensitive, ranging from sales information, health records, and credit card information to earnings statements and intellectual property.

Managing this data includes the actual transport, but also other areas such as user provisioning and authentication, enforcing rules for server access, encryption, and user bandwidth as well as visibility into server logs for reports and audits. Additionally, IT departments not only need to enable person-to-server and system-to-system interactions, but they must also enable employees to share information with each other as well as with people outside the company. All of this must be accomplished while enforcing file and data transfer policies and preventing unauthorized users from accessing private company information.

Secure Copy Protocol

July 24th, 2009

Secure Copy Protocol Overviews

Secure Copy Protocol (SCP) is method of data transmission across the network. The look is a copy of data between 2 and live a protocol similar to Secure Shell SFTP, SFTP is a different system will need to Login before it can send and receive files, but SCP will enter a password. Every time you send and receive files.

Sometimes if we want to transfer files across machines using linux for example the backup file from server 1 to server 2 or pull the file from the server down to a backup in the office we can do very easily with scp program? command scp (secure copy), on most Linux can use immediately. What not to increase but will have to Cygwin for Windows can be used prior to the regular use scp will ask for a password, but when we used to transfer or backup files, we would like to automatically set the crontab. Linux or the Windows Task Schedule in so we must skip the login process or enter the password which can be done by creating a key for the automatic login by a key 2 is a private key and public key.

How to set key step in to use scp without a login:

We will use to decide whether to use scp user? Like this in this instance I use that user name dumper.
login to a local (to get a working set that is called a local and remote access is that server) if it is possible to use the same user name on the local server or to any different after login and try pwd. We will see that in most of our home directory is / home / dumper.
Then, create private key and public key in local machine using the command

ssh-keygen-t rsa

Will have to ask about that we will file name where the key to press? Enter last name is the default value and the key storage file is created under the directory name. Ssh, if we do not create a directory. This command will create just for ourselves. After running the command above. Out file will be:
[1] private key – / home / dumper / .ssh / id_rsa.
[2] public key – / home / dumper / .ssh / id_rsa.pub
copy file id_rsa.pub to the server and rename it as authorized_keys or ftp, but may be used in this instance with scp: scp id_rsa.pub dumper@my.server.ip.addr: / home / dumper / authorized_keys. In this step will be asked for your password on the user dumper my.server.ip.addr (ip of server or domain name is optional)
login to check the server and see if the file found./ home / dumper / authorized_keys. If we are to successfully scp will find success if you do not need to copy again.
Create a directory name. ssh under our home directory (this is in the south / home / dumper), but if it is already available, then immediately move on to authorized_keys. ssh using the command mkdir. ssh mv authorized_keys. ssh.

Try to check that the file view. / home / dumper / .ssh / authorized_keys
logout from the local server is trying to scp a file will not view this time to ask password.

PuTTY

July 15th, 2009

PuTTY Overviews

PuTTY is a free program for TelNet and SSH, including service. Other protocols such as SSH PSFTP PSCP is available on Win32 and UNIX Platforms.

tunneling VNC through Putty

VNC Remote Control program is a very good one, will include two parts. As part of a Server and the Client Server will act on information management and keyboard and mouse from side to act on the Client Services section of the GUI, which may be used together. the main GUI of the system (such as all versions of Windows operating system) or may be opening a special GUI. (Such as the UNIX operating system and Linux to be more open XWindows terminal for this one) for the Client will receive the keyboard and press the mouse management. When people use the window of VNCViewer to submit to the server. And a set of instructions received from the Server to make a drawing on VNCViewer features to users of VNC is engaging is the Server and VNC Viewer on almost every flat form from any Windows version. Unix and Linux to every flat form can be used to cross out (such as opening a Linux server to run on XP and View), also suitable for use over XTerminal for Linux and Unix Especially on the network may be a break at any time where the Internet is indeed XTerminal to carry on the servers where VNCServer will clothe Terminal so we can close the window VNCViewer at any time. to reopen at another machine that the world may be different. By the software. The run will not feel the effects.

But VNC is a serious flaw is that the information sent back to the server that client is not encrypted. Of any type. Be sent in a manner that is easy to capture and analyze. This is to take the path of data sent to the VNC come through in the form of Secure shell of tunnelling.

Step process is set text terminal Putty is a very popular program. In the form of tunnelling VNC port through SSH to VNCserver by running on a Linux operating system (or other), but VNCViewer run on machines using Windows operating systems. That most users tend to use Linux or UNIX is a Riomt. General and work on a Windows operating system. Set procedures are as follow:

Open up the PuTTY Configuration window, select Connection / SSH / Tunnels.Fill Port Tunnelling through SSH to do down here, we want to tunnel through the Port of VNC, SSH, VNC uses port number 5900 to the port by 5900 to match the terminal, the 5901 match, 0. , terminals 1 to this order on Here we installing vncserver on Linux. In the case of operating system Linux and the UNIX VNCserver Xterminal will open up on new server and make connections with VNCserver (for people unfamiliar with VNCserver on Linux, we can set. the GUI is anything they wish. I like solving this case file ~ Iosesars / .vnc / xstartup. Called the line twm & a / bin / bash / bin / startkde & that it will load KDE replaces the twm) from the above example. I enter a value to the port tunnel is 5,901 (of which we are at present used by PuTTY), which is the destination. thanwa.cpe.mut.ac.th on port 5901 as a thanwa.cpe.mut.ac.th. I use a machine running the server). When I click Add it to:
After that I choose. Connecttion / SSH. To open the compression mode to allow the compression before sending data over SSH.This step is not necessary for the operation. You can skip process. If you choose to compress Will see that use VNC as a whole will be put down later. (Because data transmission is less As a result of compression).
Back to Session for convenience. I that we should set the fee for it. We enter the domain or IP of destination (run VNCServer) mode and select a contact SSH (port 22) by clicking the radio button SSH Session from the name then click Save.
Time we will use When we open PuTTy session we just kept loading. Then log in as normal text terminal ???? which we must continue to connect in SSH text terminal mode on this all the time we use VNCViewer (If we are locked out while the screen text terminal VNCViewer work will continue. incomplete. Until we close VNCViewe.
Then we run VNCViewer but when we enter the IP VNCserver we enter localhost or 127.0.0.1 instead of the value number, terminal ports is governed by the tunnel as we set in the Source port. This is a 5901 match localhost: 1.
If VNCserver worked on the servers correctly. We will see the screen password. Print it to the original.
VNCviewer started work here I have to set the Xterminal 1 (running on the console is 0) if you just run the KDE VNCserver run prior to running VNCViewer little You will see the screen while KDE is installed to monitor and work with.

Secure Shell Protocol

July 13th, 2009

Secure Shell Protocol Overviews

Secure Shell or SSH is a protocol for computer networks. Designed to log into another computer. And work. SSH is designed on a replacement for rlogin, TELNET and rsh for security reasons because SSH uses encryption methods to transmit information between devices.
Standard SSH port of SSH is port 22 also is the basis of other communications such as SFTP or SCP.

SSH Protocol History

1995 – ssh1 been invented by University of Tatu Ylonen. Technology Helsinki (HUT), Finland
1996 – ssh2 be designed and become a Internet Standard by IETF.
1999 – OpenSSH is open source.

Why use Secure Shell.

Because the old system such as a remote access telnet, rlogin, rsh no measures to secure your information. Information can be stolen easily.

Picture shows the telnet to the server data can be stolen easily.

Picture shows a server using ssh to note that the password is encrypted.

Picture shows the data transfer using Secure Shell.

How to Config Server on Linux
