File Transfer Failure

When transfering the file, I have encountered error below:

Error 7: stat: file_name: file permission denied (server msg: Permission denied, file_name)?

I have granted the proper rights(folder and user because my user was not administrator) with the link below:

Hi, does it work if you transfer the file as administrator? Also is the destination a mapped drive, share or local folder?

This article is about the program that uses SSH File Transfer Protocol (as in OpenSSH). For protocols and programs with similar names, seeSecure file transfer protocol.

sftpis acommand-line interfaceclientprogramto transfer files using theSSH File Transfer Protocol(SFTP) as implemented by thesftp-servercommand by theOpenSSHproject, which runs inside the encryptedSecure Shellconnection.[1]

It provides an interactive interface similar to that of traditionalFTPclients.

sftpshould not be confused with running anFTP client over an SSH connection.

One implementation of sftp is part of the OpenSSH project.[1]

SSH File Transfer Protocol

) is anetwork protocolthat providesfile accessfile transfer, andfile managementover any reliabledata stream. It was designed by theInternet Engineering Task Force(IETF) as an extension of theSecure Shellprotocol (SSH) version 2.0 to provide secure file transfer capabilities. The IETFInternet Draftstates that, even though this protocol is described in the context of the SSH-2 protocol, it could be used in a number of different applications, such as secure file transfer overTransport Layer Security(TLS) and transfer of management information inVPNapplications.

This protocol assumes that it is run over asecure channel, such as SSH, that the server has already authenticated the client, and that the identity of the client user is available to the protocol.

Compared to theSCPprotocol, which only allows file transfers, the SFTP protocol allows for a range of operations on remote files which make it more like a remotefile systemprotocol. An SFTPclients extra capabilities include resuming interrupted transfers, directory listings, and remote file removal.[1]

SFTP attempts to be more platform-independent than SCP; with SCP, for instance, the expansion ofwildcardsspecified by the client is up to the server, whereas SFTPs design avoids this problem. While SCP is most frequently implemented onUnixplatforms, SFTP servers are commonly available on most platforms.

SFTP is notFTPrun overSSH, but rather a new protocol designed from the ground up by theIETFSECSHworking group. It is sometimes confused withSimple File Transfer Protocol.[1]

The protocol itself does not provide authentication and security; it expects the underlying protocol to secure this. SFTP is most often used as subsystem ofSSHprotocol version 2 implementations, having been designed by the same working group. It is possible, however, to run it over SSH-1 (and some implementations support this) or other data streams. Running an SFTP server over SSH-1 is not platform-independent as SSH-1 does not support the concept of subsystems. An SFTP client willing to connect to an SSH-1 server needs to know the path to the SFTP server binary on the server side.

Uploaded files may be associated with their basic attributes, such as time stamps. This is an advantage over the commonFTPprotocol.

The Internet Engineering Task Force (IETF) working group Secsh that was responsible for the development of theSecure Shellversion 2 protocol (RFC 4251) also attempted to draft an extension of that standard for secure file transfer ternet Draftswere created that successively revised the protocol into new versions.[2]The software industry began to implement various versions of the protocol before the drafts were standardized. As development work progressed, the scope of the Secsh File Transfer project expanded to includefile accessandfile management. Eventually, development stalled as some committee members began to view SFTP as afile systemprotocol, not just afile accessorfile transferprotocol, which places it beyond the purview of the working group.[3]After a seven-year hiatus, in 2013 an attempt was made to restart work on SFTP using the version 3 draft as the baseline.[4]

Prior to the IETFs involvement, SFTP was a proprietary protocol ofSSH Communications Security, designed by Tatu Ylönen with assistance from Sami Lehtinen in 1997.[5]Differences between versions 02 and version 3 are enumerated upon insection 10 of draft-ietf-secsh-filexfer-02.

At the outset of the IETF Secure Shell File Transfer project, the Secsh group stated that its objective of SSH File Transfer Protocol was to provide a secure file transfer functionality over any reliable data stream, and to be the standard file transfer protocol for use with the SSH-2 protocol.

Drafts 00 – 02 of the IETF Internet Draft define successive revisions of version 3 of the SFTP protocol.

The termSFTPcan also refer toSecure file transfer program, athat implements theclientpart of this protocol. As an example, the sftp program supplied withOpenSSHimplements this.[6]

Some implementations of thescpprogramsupport both the SFTP and SCP protocols to perform file transfers, depending on what the server supports.

SomeFTP server implementationsimplement the SFTP protocol; however, outside of dedicated file servers, SFTP protocol support is usually provided by anSSH server implementation, as it shares the default port of 22 with other SSH services. SFTP implementations may include an SSH protocol implementation to leverage integration of SSH connection details with preexisting FTP server access controls, where an alternative SSH server is tolerable or where alternative ports may be used. An SSH2 server which supports subsystems may be leveraged to keep a uniform SSH implementation while enhancing access controls with third party software, at the cost of fine-grained integration with connection details, and SSH1 compatibility.

It is difficult to control SFTP transfers on security devices at the network perimeter. There are standard tools for loggingFTPtransactions, like TISfwtkor SUSE FTP proxy, but SFTP is encrypted, rendering traditional proxies ineffective for controlling SFTP traffic.

There are some tools that implement man-in-the-middle for SSH which also feature SFTP control. Examples of such a tool are Shell Control Box fromBalabit[7]and CryptoAuditor fromSSH Communications Security[8](the original developer of the Secure Shell protocol) which provides functions such as SFTP transaction logging and logging of the actual data transmitted on the wire.

ssh authentication methods

Rather than prompting you for your password on the remote computer when making connections, you can configuresshto use alternate authentication systems, some of which require no password. This page describes the specific methods for doing this on Unix systems. Macintosh and Windows PC ssh clients may support similar processes with a different method.

Thesshprotocol allows system managers of cooperating computer systems to permit ssh connections between the accounts of the same names on either system without requiring a password. This option uses the same system or user level.rhostsfiles that are required for the Berkeley Unixrcommands. This type of authentication should only be allowed under systems that are managed together, because it requires complete trust between the systems. Just like thercommands, it means that if a hacker breaks into your account on one system, he has access to your account on the others with no need for any password. Unlike thercommands, the actual data transferred during connections is encrypted.

Neither pangea nor the Sweet Hall workstations allow this type of password-lesssshconnections using.rhostsfiles.

Thesshprotocol provides a third authentication option: private cryptographic keys. This option, which is available on pangea and the Sweet Hall systems, lets you use a special program to create a pair of public and private cryptographic keys that are specific to your account on a particular computer. Your private key, which you must keep secret, is used to encrypt communications. Your public key can only be used to decrypt and must be stored on each system to which you want to connect. These public/private encryption keys are virtually impossible to break.

Private cryptographic keys can be used in thesshprotocol for either one of two conflicting purposes: to add a higher level of security to your connections, or to add convenience by eliminating the need for providing passwords.

To make your connections even more secure, which is the recommended use of private cryptographic keys, your private portion of the key pair is itself encrypted with a pass phrase that is not stored anywhere in the computer. A pass phrase is like a password, except that it can be an arbitrary length phrase of multiple words; a phrase of 10 to 30 characters is recommended. When you makesshconnections using private crytographic keys that have been protected with a pass phrase, not only must you install the public key in advance on the remote systems, but you must supply the pass phrase at time of connection in order to read the private key. Because these pass phrases can be different from and longer than your normal account password, the likelihood that they can be guessed by a hacker is dramatically reduced.

You can also use private cryptographic keys insshto provide more convenient, password-less connections, but at some loss of security. You do this by creating the keys with a null pass phrase (you simply press theRETURNkey when prompted to set the pass phrase). You then store the private key on the local computer in a file with permissions set to prevent other accounts from seeing it, and you copy the public key to the other computers to which you want to login. Now you can usesshto make remote logins, transfer files (see below) and run remote commands (see below), all with full data encryption, between your local computer and those remote ones without ever needing to supply a password. The danger is that if a hacker obtains your private key, he can then access your account on the remote computers as well. This is the same danger that comes from enabling.rhostsauthentication (see above), but applies only to your account and not to the whole system.

How do you create and store the private cryptographic keys to use withssh? On Unix systems, you use thessh-keygenprogram. On pangea, this is not located in one of the standard system directories, so you have to specify the complete pathname of the program to run it, as:

No arguments are needed.ssh-keygenwill make a pair of random private and public keys that work together. It will then prompt you for a pass phrase that is used to further encrypt the private key. If you want added security, supply a phrase. If you want the added convenience of password-less connections, simply press theRETURNkey to create a null pass phrase.

ssh-keygenautomatically stores the newly created cryptographic keys in the.sshsudirectory of your home directory, in the filesidentity(for the private key) andidentity.pub(for the public key).

Theidentityfile will be made with no permissions for any other account to access it because the private key stored therein must be kept secret. Make sure that you never turn on read or writepermissionfor group or others to this file, or to the.sshsubdirectory, particularly if you set a null pass phrase.

The public key in theidentity.pubfile must be copied to the other computers to which you want to connect with ssh. On remote Unix systems, you append the contents ofidentity.pubto the fileauthorized_keysin the.sshsubdirectory of your home directory. The location of this file may vary for non-Unix servers.The simplest way to copy this file is to usescp(the file transfer function of ssh) to copy it to the remote system and thenconcatenateit to theauthorized_keysfile withcat.

Encountered 1 errors during the transfer

Hello I installed SSH in my windows XP machine. I am connecting to a Linux machine using SSH. I simply drag and drop the files to transfer it under SSH program. Yesterday, while I dragged and dropped, the cursor did not come back and I am not able to transfer any file into the linux server using the ssh program. I reinstalled the SSH program. I tried to transfer files using SSH program to other linux machines and this works. But when I try to transfer files to this particular server where I got the error, I am not able to transfer even a simple text file. I tried to do this from two different XP machines. I am not sure what to do to fix this problem. I killed all the processes in the linux server which were running under my user name. Still it does not allow file tranfer under SSH.

I got this error msg when I clicked on the error box

Error 8: /home/saras/2ADX(2).dssp (dst): undefined error (server msg: Failure)

saraswathi551111

I think the problem was that there was no disk space in this linux server. It would have been nice if the SSH program said there is no space instead of saying error encountered. I found this out by trying out scp from the command line to get to that server.

Using SSH Secure Shell to Transfer Files with sftp [Windows

This document describes how to use the SSH Secure Shell included in the Information and Technology Services (ITS) Windows Internet Access Kit to copy, or transfer, files from one computer to another over the Internet. SSH uses sftp (secure file transfer protocol).

Download afree stand-alone SSH Secure Shell installer. You will need to authenticate with yourU-Muniqname and UMICH (Level-1) password.

ITS provides a number of shortcuts to make it easier for you to open secure file-transfer connections to popular host computers atU-M. (A host computer is one that allows other computers to connect to it; it hosts connections from other computers.) Heres how to use the shortcuts.

Make sure you have a working Internet connection. If you use a modem, establish a dial-up connection. If you use Ethernet, your connection should already be available.

Double-click theSSH Secure File Transferfolder.

The shortcuts are right there. To open a file transfer connection using a shortcut, double-click the shortcuts icon. For example, to connect to your ITS-provided AFS home directory, double-click theITS Home Directoryicon. (You might have to single-click some icons to see their full names.)

Double-click theITS Home Directoryshortcut to open a connection you can use to transfer files to and from your home directory. SSH will open.

In theConnect to Remote Hostdialog box:

In theUser Namefield, type your uniqname.

NOTE:For an SFTP file transfer connection to AFS, use thesftp.itd.umich.eduhost name.

In theEnter Passworddialog box, type your UMICH (Level-1) password, then clickOK.

THE FIRST TIME YOU CONNECT:The first time you connect to any host computer, you will see aHost Identificationdialog box asking if you want to save the new host key to the local database. ClickYes.

CAUTION!Use your uniqname and UMICH (Level-1) password with SSH Secure Shell for SFTPonly when connecting toU-Mhosts.Do not use them with non-U-Mhosts. Some host computers atU-M– such as those run by individual schools, colleges, or departments — may require different user IDs and passwords.

A window showing your local computer on the left and your home directory on the right will open. You are now ready to transfer files.

Transfer files by dragging their icons from one side to the other of the window. You can copy files from your local computer to your AFS home directory and vice versa.

On the home directory (remote) side of your window, click a file to select it.

From theOperationmenu, selectDelete.

In theConfirm deletedialog box, clickYes. The file will be deleted.

On the home directory (remote) side of your window, click a file to select it.

From theOperationmenu, selectRename.

The file name will become editable. Make whatever changes to the file name you wish.

Click anywhere outside the file name to save the changes.

In theConfirm Disconnectdialog box, clickYes. This will close your connection to the host computer. It will not disconnect your dial-in or other connection to the Internet. The window turns gray, to show that you are not connected. And there is a not connected line at the bottom left of the window.

WARNING!Your computer account will continue to accrue dial-in charges for as long as you have an open modem connection to the Internet. Close your modem connection any way possible, even if it means turning the power off to your modem. You are responsible for all charges.

To exit SSH Secure Shell, pull down theFilemenu and selectExit.

Open SSH Secure Shell for file transfer by double-clicking theSSH Secure Shell File Transfericon. An SSH Secure Shell file transfer window will open.

HINT:Do not double-click theSSH Secure Shell Clienticon; that will open a terminal connection instead of a file transfer connection.

In theConnect to Remote Hostdialog box:

In theHost Namefield, type the host computers address.

In theUser Namefield, type your user name for the computer to which you are connecting. (For mostU-Mcomputers, use your uniqname.)

In theEnter Passworddialog box, type your password for that computer, and clickOK.

THE FIRST TIME YOU CONNECT:The first time you connect to any host computer, you will see aHost Identificationdialog box asking if you want to save the new host key to the local database. ClickYes.

CAUTION!Use your uniqname and UMICH (Level-1) password with SSH Secure Shell only when connecting toU-Mhosts. Do not use them with non-U-Mhosts. Some host computers atU-M– such as those run by individual schools, colleges, or departments — may require different user IDs and passwords.

Why You Need an SSH Secure File Transfer Client

U.S. 1.786.375.8091UK EUR 44.20.7193.2879

Posted byJohn Carl Villanueva on Wed, Sep 18, 2013 @ 02:26 PM

The Internet is increasingly becoming too risky for transmitting sensitive files. Several network hacking tools are now being shared freely on the Web, making them easily accessible to professional cyber criminals and script kiddies alike. One way of protecting your files from these threats is by sending them via SFTP, a method that requires an SSH secure file transfer client.

Most of the methods we use for sending files over the Internet, like email or FTP, are actually very vulnerable to attacks. When weFTP a file, for example, the information is sent as plaintext. What this means is that, given the right tools, a hacker can easily carry out a man-in-the-middle attack, sniff our FTP connection, and view the information being sent – including our FTP username and password.

Heres a screenshot of a packet sniffer (a network hacking tool) eavesdropping on an FTP connection.

Once the crooks have obtained our login credentials, they can just simply login to our FTP server and grab whatever files they find.

To know more about sniffing, man-in-the-middle attacks, how such attacks are carried out, and how encrypted file transfers defeat them, read the articleCountering Packet Sniffers Using Encrypted FTP.

SFTPa.k.a. Secure File Transfer Protocol a.k.a. SSH File Transfer Protocol protects file transfers from various threats. It does this in two ways:

1. It encrypts the file transfer connection and

2. It provides stronger authentication

Encryption renders data unreadable. The data can only be made readable again after it has been decrypted. In an SSH file transfer, data is encrypted throughout the SSH connection. Decryption is done at both ends, i.e., at the server and at the client.

Thus, any attempt to eavesdrop on an SFTP file transfer using a man-in-the-middle attack will not succeed.

Heres a screenshot of the same hacking tool shown earlier, this time displaying an attempt to eavesdrop on an SFTP connection. Notice how the transmitted data is no longer comprehensible.

To authenticate users connecting to the server, file transfer methods like FTP only require a username and password. Now we all know just how easy it is to obtain those login credentials using a packet sniffer. But if the connection is encrypted, then those login credentials are already safe, right? Wrong.

There are many sinister ways of obtaining passwords.

Crooks can perform various social engineering acts like shoulder surfing, phishing, or simply impersonating a legit user and calling a gullible Help Desk agent. More technically skilled individuals can even carry out abrute force attack on the serveritself and steal a bunch of usernames and passwords.

SFTP can make things more difficult for them crooks. Thats because anSFTP servercan apply two methods of authentication. The first one asks for something only the user is supposed to know: the users username and password. And the second one asks for something only the user is supposed to have: the users private key.

This second method, known as public key authentication, enhances the authentication process quite considerably. Even if an attacker is able to obtain a users login credentials, he wont be able to login without the users private key.

The articleRoles of Server and Client Keys in Secure File Transfersoffers a very informative discussion on public key encryption and authentication.

In order to upload or download files to/from a SFTP server, you would of course need a SFTP client or SSH secure file transfer client.

A SSH secure file transfer client typically supports not only SSH encryption but also public key authentication. In other words, it normally provides the option for attaching a private key file. In the SFTP client shown below, the user can enable password authentication, public key authentication, or both.

When choosing a SFTP client, it would be wise to pick a product that readily supports other secure file transfer protocols. That way, you could also use it to connect to other file transfer servers likeFTPS, WebDAV,Amazon S3, and others.

Another consideration is support for the operating systems running on your users computers. If your SSH secure file transfer client only runs on Windows, users who work on Mac or Linux machines would be left out.

That means, your Network Administrator wont be able to upload from his Linux desktop. Or, worse, your boss (whos out of town) wont be able to download a financial report unto his MacBook Air.

AnyClientis a free, platform-independent SSH secure file transfer client that runs on Windows, OS X, Linux, and Solaris. It supports a wide range of fast andsecure file transfer protocols, including FTPS, SFTP, WebDAV/S, Amazon S3 and AFTP. Still using FTP? Yes, AnyClient supports that as well.

I can access and manipulate the files on the remote computer using command line tools, and can even transfer them from one computer to the other using scp. My question is if I am on my work computer (local) and connect to my home computer (remote) with a SSH, as I browse through the files on the home computer can I copy them to my local work computer without having to type in the whole IP addresse etc.

Etresofts MacFUSE is one (rather good) idea.

You could write scripts that hardcode the remote IP address into scp commands. I use this trick for copying files to a remote system. The files all get put into my remote Download folder, which I then move around as needed when Im on that remote system. Not exactly the same as what you want, but the concept is similar.

You could get a free dynamic DNS name from a services such as No-IP.com or , and then you would not need to bother with the IP address. I use these for my home and my Moms remote location.

You could use ssh to establish a tunnel to the Apple FileSharing (AFP) port 548 so you can mount the remote file system. I do this when connecting to my Moms system. Ive scripted the task so I do not need to manually type in the long ssh command (ssh -L 12345:localhost:548 remote.system.address). Then Finder – Go – Connect to server – afp://localhost:12345, where the 12345 is the local port number of the ssh tunnel that leads to the remote systems AFP port 548.

The ssh tunnels also all screen sharing (port 5900) over secure ssh connection (ssh -L 54321:localhost:5900 remote.system.address and using vnc://localhost:54321 to connect, where 54321 is the local side of the ssh tunnel that leads to the remote VNC port 5900).

You could use a services such as TeamViewer.com that allows file transfer along with screen sharing.

There are others, some free, so fee based, that offer similar services.

Thanks so much! Just the point in the right direction I needed. I now have my remote file system up and running.

I used Estresofts idea and think Ill stick with it for now as it is still completely client based and does what I want. Thanks for the help though and I did have a rough applescript set up to auto download/upload files as you suggested but a mounted file system that can act just like a local disk is just so much easier even if I dont have quite as good a hands on approach as Id like.

Making a Connection to i4 with SFTP

Viewing and Modifying Permissions with SFTP

SSH File Transfer Protocol(alsoSecure File Transfer Protocol, orSFTP) is a network protocol that provides file access, transfer, and management on remote file systems. Unlike standard File Transfer Protocol (FTP), SFTP encrypts both commands and data, preventing passwords and sensitive information from being transmitted in the clear over a network.

At NYU, we require SFTP for file transfers, and recommend using a graphical SFTP program for access to the web server. ITS distributesFetchsoftware (for Macintosh), and the NYU Web Team supportsFugufor Macintosh, andWinSCPfor PC.  While you may use other programs, such asCyberduck,Dreamweaver, andTransmit, they are not supported by the NYU Web Team.

You may alsomanage your file permissionsusing your SFTP client.

Transferring Files

Transferring Files with the SSH Secure Shell FTP Client

You have a photograph taken in the DERR 325 lab. The file is named, MVC-058F.JPG.

You have transferred the file to your My Pictures folder on your (local) Workstation (Look for the My Pictures folder under the My Documents folder.)

Note:The following demonstration assumes the existence of a My Pictures folder. You may not have a My Pictures folder on your local Workstation. Save the file containing the picture the folder of your choice.

e.g. C:\Documents and Settings\br02\CS1308 where the folder CS1308 was created by the user br02.

You want to transfer this file to our Server and into the website folder (the Web-accessible folder).

We will use the SSH Secure Shell FTP

Program. If you choose to install it on you own computer, the program is available at the following local address:

or from the source:Our Web servers Internet address is:students.its.txstate.edu(147.26.110.202).

NOTE: The related icon:willNOTwork for your account.

Complete the resulting dialog box as shown below:

Note:Theleft-hand pane(below) shows the files, folders, etc. available on your Workstation (PC). Theright-hand pane(below) shows the same resources available on the server. In this example, we will be dealing with thewebsitefolder. Thecgi-binwill be used later.

Double-Click on theMy Documentsfolder in theleft-hand pane, and double-Click on thewebsitefolder in theright-hand pane. We get the following:

Click on OK in the Transfer Error Dialog box (This is a known problem, but the transfer will still tersettings will be provided to prevent this from from occurring):

A similar process will transfer files (Using
