SFTP ; SSH_FX_FAILURE:

Hi.
I am trying to do a fsetstat on a file using sftp:
fileAttributes = sftpClient.fstat(fileHandle);
fileAttributes.permissions = new Integer(00777);
sftpClient.fsetstat(fileHandle, fileAttributes);
The files permission gets changed as requested on the server but an exception gets thrown, I can�t figure out why the exception is thrown :SSH_FX_FAILURE: An error occurred, but no specific error code exists to describe the failure.
I am able to do createFile which indicates that my connection and file handle is working...
Also the file gets created by the process and therefor I have all the neccesary permission to make changes to the file.
Thanks

This is not a permission problem but a problem between Contribute and the FTP server. This is an issue that has been around for at least 5 years, best I can tell. We are seeing the Contribute user log in just fine but when they want to edit a file Contribute immediately tries to read the .lck file which returns an "Access Denied" error. The .lck file does not exist at this point which is causing this whole problem. If I create a blank text file and name it "default.htm.lck" and then try to edit the default.htm things are just fine. The user clicks the edit button, Contribute makes a call to the file system to read the .lck file, finds it, it's blank and has no information to read so it goes ahead and lets the user edit the page. When the user finishes the edit and uploads the file Contribute deletes the .lck file and then back to the "Access Denied" error for the next time.
To test this I have two sFTP servers and one web server. The two FTP server authenticate via Active Directory and connect to the webserver via UNC paths. The two FTP servers are running different software for the FTP part, one works the other does not.
trying to get a nonexistent file from the working FTP server results in
Code:
psftp> get bla.htm
/bla.htm: open for read: no such file or directory
trying to get a nonexistent file from the other FTP server results in
Code:
psftp> get bla.htm
/bla.htm: open for read: failure
From what I can gather at http://www.justskins.com/forums/contribute-cannot-edit-files-over-sftp-4977.html the server is returning an error code 4, a general sftp error. what Contribute is expecting is a error code 2, file not found. Why some FTP servers return the error code 4, I have no clue. But who thought it would be a good idea to open a file that may or may not exist? Wouldn't it have been easier to check for the lck file first?

Using secure FTP (SFTP) with XI 3.0.

Hi,
I must bring a document with SFTP protocol.
Is it possible use SFTP with XI 3.0. What must I do use SFTP with XI. Is it necessary to install some component to XI or it needs some 3hrd party components?
Thanks

Hi Cemil,
Right now, XI does not have the feature of communicating with SFTP. You can extend the functionality of the File Adapter by writing some adapter modules to enable it to communicate with SFTP.

Java SFTP API/Sample application

I'm looking for either sample java code of how to send files via sftp or a java api to do this. Jscape looks to be the standard for doing this although it costs quite a bit, wondering if there is free code out there?
Thanks for any help in advance!!!

Check out JCraft's Java Secure Channel (JSch) project -- it's an implementation of SSH (with scp, sftp, etc.) in Java -- with some examples that might get you started: http://www.jcraft.com/jsch/
The code is distributed free under a BSD-style license which is described on the site.

Cannot login via ssh/sftp from certain clients

Hi Guys,
Strange issue here. I have a machine running 10.7.4 that I want to be able to access via sftp/ssh.
I can login into the machine in terminal using either ssh or sftp.
I cannot however login to the machine from finder via sftp. I am just told the username/password is wrong.
Equally I cannot login to the machine from certain clients on my android phone (the main reason I need sftp)
I can however login from cyberduck on the other machines I have, and from some clients on my android phone.
When a mac is denied access it gives authentication failed as the reason, when a android client is denied access it gives network communtaction issues as its reason for failing, not authentication.
From memory these issues started when smb broke for me in 10.7.3.
Can any one shed any light on this?
Cheers

Trigger File Option in SFTP Advantco Sender Adapter

Hi ,
What is the purpose of Trigger file option in sender SFTP adapter?When i enabled Advance selection for source file we have this functionality.Can i use this option to delete the multiple files in the same directory instead of using File Name Mask.
We have scenario to delete 4 files from application server in that only one file should be sent to partner and the rest should be delete from application server.
Actual solution is to use to use script to delete the rest of the files do we have any other alternative.
Thanks

Hi,
Another alternativet is to write your own customer adapter module and using java programming you can delete remaining 3 files. This is bit complex comapre to script writing but one advantage is with adapter module is that, you can provide the deteted file names with time stamp in the audit log of XI message, which will help in troublshooting if some issue happens.

Sftp batch job with password?

Hi folks.
We're trying to develop scripts to automate the transfer of files from various Windows machines to a Linux server. Because the job involves moving multiple files to multiple directories, I wanted to use sftp's -B batchfile option to transfer the files instead of having to reauthenticate every time we transfer files to a different location. However, the man page says:
Batch mode. Reads commands from a file instead of standard input. Since this mode is intended for scripts, SFTP2 will not try to interact with the user, which means that only passwordless authentication methods will work.
I would love to use keys to get this done but unfortunately, the type of authentication on the server is out of our control and not likely to change (it's straight password). So, is there any way I can do this in batch mode with password authentication? I thought about using scp but, as far as I can tell, it doesn't have great support for delivering multiple local files (in different locations) to multiple remote locations. One would have to re-authenticate for every scp command, right?
Any help would be appreciated. Thanks.

Thanks for the recommendation, Endperform, but after reading up on expect and autoexpect, I realized I'd rather not have usernames and passwords hard coded into the script.
After much research, I think I've found a solution. It's a little odd but the Maverick Ant library does exactly what I need it to do. It can actually read an ssh profile, perform multiple transfers without having to re-authenticate and execute multiple remote commands without having to reauthenticate. The native Ant libraries can't do this. There is no sftp Ant task and the scp and sshexec tasks are lacking to say the least.
If anyone else runs into a similar situation, I highly recommend the Maverick tool.

How to open a non-default port for sftp?

My MacMini at work used to listen on port 12345 for sFTP for close to 9 months but then something (probably a power cut...) messed all things Remote up with the office setup. So I tried to reset things. It didn't work. What do you think I'm doing wrong? The MacMini is running Tiger (10.4.10). Here's what I've done so far:
1. Drilled a hole for port 12345 on my Thomson (Alcatel SpeedTouch 780) modem/router, and disabled its Firewall and Parental Controls;
2. In System Prefs>Sharing>Firewall I have enabled the Firewall after making sure I've added a service for port 12345;
3. Also in System Prefs I've enabled Remote Login, to make sure the sftp daemon is running;
4. Back on the Thomson modem/router, I've set up a service to forward port 12345 of the router to port 12345 of my MacMini (I selected it by clicking on its MAC address in the appropriate drop down menu in the modem/router config page).
STILL: when I try to sftp to my MacMini from outside the office, I get a timeout error. Back at the MacMini, I run Network Utility and ask it to check at IP (the MacMini IP) for ports 12345 to 12345, and it doesn't report it as 'open' (it does for port 22).
I am bummed. What am I missing? I am also 100 miles away from the office on any given day, so it's not exactly easy to pop over and try various troubleshooting things. I have to kill this once and for all next I'm at the office, some time in the weekend!
As always, thanks, people.
< Edited by Host >

It sounds to me like the port forwarding is setup, so that's not the issue.
The issue is how to change sshd to listen on port 12345 rather than port 22. However, I'm not sure that you need to.
If you're trying to hide your server from the public, why not just setup your port forwarding to forward publicIP:12345 to privateIP:22.
That way you connect to port 12345 from your remote location, but don't have to change the server configuration at all.
The only reason why this wouldn't work would be if your router doesn't support different internal and external ports (e.g. it always maps to the same internal port number).
If that's the case then you need to change launchd to listen on port 12345. How you do that depends on whether you want to move the entire SSH service to port 12345, or whether you want SSH to support 22 and 12345 at the same time.
If the former, just edit /System/Library/LaunchDaemons/ssh.plist and change the lines:
<key>SockServiceName</key>
<string>ssh</string>
to:
<key>SockServiceName</key>
<string>italk</string>
(italk is the registered service for port 12345).
Then either reboot or unload/reload the ssh.plist to make the change active.
If you want ssh to run on both port 22 and 12345 then you should copy /System/Library/LaunchDaemons/ssh.plist to /Library/LaunchDaemons/ssh-12345.plist then make three changes to the new .plist file:
First, change the <Label> parameter to something unique (i.e. not 'com.openssh.sshd').
Second, remove the <Bonjour> array
Third, edit the SockServiceName as indicated above.
Once you've done that, reboot and you should be set.

File not found error in SFTP channel

Hi All,
We are getting a "file not found error " while using a SFTP sender channel .
Our Scenario :
We are using SFTP as the source adapter .Presently we are using two nodes for load balancing for all the sender channels.
One of the node's of the SFTP channel is picking the file , while the other node at the same time is throwing a "File not found error".
The file is being picked and is placed at the target, but the channels are in error state as one of the nodes is in error state.
Please let me know, if we did any mistake while configuring the adapter.
Thanks,
Yamunan

Hi,
Could you please check if you have provided right path in your sender communication channel...to pick the file from...

[Solved for me]Distinguishing SSH and SFTP (for QoS purposes)

Hi there,
I'm thinking about shutting down the FTP on my homeserver and use SFTP instead. There is only one thing I couldn't solve so far: In my router I have QoS-rules that make FTP low priority traffic so my normal activities don't get affected by the file transfers. I would like to have the same setup for the SFTP. Now the problem is this: SFTP and SSH are both coming from the same ssh server, listening on port 22. So there is no way of distinguishing them on a ip/port basis. Is there any way of distinguishing SFTP and SSH? Like using iptables to tag one of them and then doing QoS based on the tag or something along those lines? I don't want to slow down my ssh-connections together with the sftp. If anyone has an idea how to accomplish this I would be really glad to hear about it.
Thanks in advance

Thanks for this hint, I didn't know that ssh could listen on multiple ports. Its not totally bulletproof, but good enough for my case. The only people who will have access to the server are trustworthy and won't fiddle with the settings to circumvent my restrictions.
Thanks to all of you for your suggestions.

How to delete zip file in sftp server

Hi Gurus,
I am having one .zip file with data files inside on the sftp server. Can you please how to delete the .zip files in the sftp server. I am able to delete normal files by using 'rm' on sftp.
And one more request my sftp is prompting for the password everytime, then i need to enter the password manually. Can any one suggest how to write in shell script to accept that.
Thanks in advance.
Regards
Nagendra

You might want to look into user equivalence and configure a certificate for ssh so it does not prompt for a password.
It will also allow you to use sftp without a prompt for a password.
On the server side:
Edit /etc/ssh/sshd_config and remove the # from the following:
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
Then restart the ssh server:
/etc/init.d/sshd restart
Login as the user for whom this is for:
su - <username>
mkdir .ssh
chmod 700 .ssh
On the client side:
Run the following command:
ssh-keygen -t rsa (omit password)
Then use the following to copy the public key from the client to the
corresponding login .ssh directory on the server side;
scp .ssh/id_rsa.pub username@remote_host:.ssh/authorized_keys

Can't establish a sftp connection with the finder

Hi, I'm trying to establish a sftp connection with the finder (using the "Connect to server" feature) between my (recently purchased) Mac Mini (mid 2011: i5, 2.3 GHz, 2 GB, running 10.7.3) and a Debian Testing box and I can't, I get the following error:
'There was a problem connecting to the server "ip.address"
This file server will not allow any additional users to log on. Try to connect again later.'
However if I try establishing a connection from the terminal (either ssh or sftp) it works flawlessly:

I've searched for a fix or alternative on the internet and I haven't found one that works; The one that keeps coming up is to try: "ftps" as the protocol instead of "sftp" with the remaining information the same (it doesn't work, it gets the same error message afterwards).
The IP address and login information works (corroborated by the fact that I can log in from the terminal from the Mac Mini) so the only issue is with the finder capabilities for establishing the connection. I have looked for apple related documentation or How Tos but I haven't found anything useful.
I don't want to use any third party app or tweak because of the sensitive information that is going to be transfered, I would like to be using strictly the tools from the OS.
If you need any more information please let me know, any help is deeply appreciated.

I have the same issue although i kind of fixed it. I have two admin accounts and one of the account's safari did the same thing as yours, except, it was the startpage and everypage i tried to visit. I reseted safari, as in the erase all data safari in the toolbar, safari-Reset Safari... But safari still didn't work. I logged out and went to my other account and opened safari. Now it works fine on both accounts. This meant safari had to logout before actually working better. I have this a few times these days.
