Recurring ftp connection problems with CS3

I've been experiencing recurring connection problems to a live server.
The settings have not changed, and the "test" verifies connection is working.
I can connect to the site via ftp successfully using the same information.
All I see in the remote server box is /www/ , I cannot open the folder however.
The only way to resolve is to delete my profile on the computer and recreate.   This fixes it for up to 1 week, but sometimes as little as 24 hours.
Others who log in to the same machine and use Dreamweaver are able to connect successfully.
I work on a network and do use 2 separate work stations.   On one of these workstations is also installed Avid Newscutter, the full Adobe CS suite and a programme called Flip (for working with xml).    I had no problems until I started working at this terminal.
The company technical support is at a loss, so I was hoping folk here might have some suggestions? I've been using Dreamweaver, various versions both at work and home for many years and have never experienced a problem like this before.
thanks.

Hi Jon
I am getting two error messages, one that says that the log on info/password is wrong, the other is a large message that tells me to check everything from cables to firewalls. My provider has recently been updating their systems and I have had to change passwords etc, but they insist that it is nothing to do with them. I am sure that they have changed some protocols or something that dreamweaver won't recognise.
I am connected to the internet via a cable to a belkin router and have no problems with internet connections.
I have tested the adobe ftp test connection through dreamweaver which worked fine.
I haven't tried filezilla - I'll have a look.

FTP Connection Problem with DW CS3

Someone gave me some FTP info to use to connect to their
server and I have never seen FTP info like this nor can I figure
out how to get DW CS3 to connect to it. I can connect to the site
using an FTP program like Filezilla, but can't seem to find the
settings to get it to work in Dreamweaver. Any thoughts would be
appreciated. Here is the example of the info...
ftp://www.mysite.com:20
User Name: User
Password: Mypassword
That is all the info they gave. I think the ":20" is the port
number on their server, but I can't figure out how to use that in
Dreamweaver. I have tried getting rid of it and also just using
mysite.com as the FTP. None of those work. Any ideas how to use
this to connect?

FTP Host -
www.example.com:20
connection information as shown....

FTP Connectivity Problem

Hi guys,
I am still muddling around with my initial configuration of the ACS solution engine 4.1
I was trying to install the "Generate the Self-Signed Certificate" but unfortunately when i enter the FTP hosts ip and a username/login followed by the "/" directory.
An error saying verify FTP username/password comes up. On a win2003 server i installed IIS and the FTP component.. and set the ip as 10.c.a.b for the default ftp site. and have been trying to connect to this from the acs box.
Any suggestions as to why the error is cropping up?
To complete the picture.. i have the Win2003 server and the ACS solution engine on the same switch as well.
My ACS can also view all the groups in the AD and stuff, so i do know there is connectivity between the win2003 and acs box..
please help :(

hi andrew..thank you for ur help
but i realised something really really stupid :) The ftp site and all were working from the command prompt.
The only mistake was i forgot to add the domain name in the USERNAME section... i just kept trying with a user account from the AD .. but without adding the domain name.
It works now :) Have the certificate installed... now i need to figure out, how to get Dynamic Vlans and get DHCP service working for each of these dynamic vlans
have u worked on the ACS 4.0 soln engine b4?

Ftp connection problem with cs5.5

Hi,
   I am jsut starting to use the Dreamweaver part of CS5.5 after upgrading from CS4. I have been trying to access my previous
web sites using ftp as I have done before. The pop up window asks for the ftp address which is ftp.sonic.net/pub/users/us and
the root directory which is /home/WWW_pages/us . But the pop up box keeps changing the root directory to /pub/users/us and
setting the ftp address to ftp.sonic.net whch doesn't work.
How can I work around this?
                           Thank you,
                                          ~Vonnie A

Based on instructions on the sonic.net site

try
FTP: ftp.sonic.net
Root directory: /home/WWW_pages/us or /home/www_pages/us

FTP/SSL Connection Problem for FTP Receiver Adapter

Hello All,
We are trying to establish an FTPS/SSL connection with one of our customers from our XI(Unix) system, and are receive following error:
iaik.security.ssl.SSLException: Server certificate rejected by ChainVerifier
Communication Channel Parameters:
Connection Security: FTP (FTP Using SSL/TLS) for Control Connection or FTP (FTP Using SSL/TLS) for Control Connection and Data Connection
Command Order: AUTH TLS, USER, PASS, PBSZ, PROT
Checkbox - Use X.509 Certificate.... checked (Certificate was provided by third party (customer issued) and uploaded to service_ssl certificate store on J2EE server)
Data Connection: Passive
Port: 10021
Keystore: service_ssl
X.509 Certificate & Private Key: ssl-credentials
Note: Initial handshaking occurs but connection is being dropped by the third party FTP Server when SSL certificate credentials are being validated. We also tried connecting to the third party FTPS server using standard FTPS client(FileZilla software), this connection gets established successfully with no certificate issues which means certificate and third party FTP Server is functioning correctly.
We therefore are thinking that the problem lies with our XI system being unable to load the certificate information correctly at the point when FTPS session is being established.
Your help and suggestions will be greatly appreciated.
Thanks and Best Regards

Hello All,
Further in order to test connection set up and communication channel configuration we tried simulating the FTP connection locally by configuring FTP Server using FileZilla at a local machine and accessed it from Client's XI Server.
This set up simulates the problem we encounter with our customer's FTP Server.
If connection security parameter in communication channel for Sender FTP Adapter is set to "FTPs( FTP Using SSL/TLS) with Control Connection" only, file gets successfully created with data at the FTP server but as soon as we switch the connection security parameter to "FTPs( FTP Using SSL/TLS) with Control and Data Connection", we receive error "Certificate rejected by Chain Verifier". The initial handshaking happens successfully and file gets created at the FTP Server but its empty, connection fails when attempt is made to write data into file and we end up with said error thereby closing the connection.
This is what the FTP (FileZilla) sees when the XI system attempts to set-up a fully encrypted data (FTPS) connection i.e., connection security parameter value as"FTPs( FTP Using SSL/TLS) with Control and Data Connection" :-

FTP Server connection Problem

Hi Friends
we trying to Configure the File to File Scenario.. and message is processing successfully in SXMB_MONI
but in the runtime workbech we have the error in communication channel.
Error when getting an FTP connection from connection pool: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: FTPEx: Login incorrect.
we cross checked the Login credentials and did Full cache refresh..
still facing same problem.
Please help me on this
Regards
Sandeep

Check if this helps: FTP connection error whil,e using flat file adapter error
Recheck the FTP details: /people/shabarish.vijayakumar/blog/2006/08/01/along-came-a-file-adapter-mr-ftp-and-rest-of-the-gang
The user-id & password used in file channel should be same as it is in the ftp....may be there is some change (some case-issue)

Broken Ftp Connection and big files problem

I have a problem with big-files downloading.
Does anybody know how to resume downloading using FTP-connection?
Or how can I get bytes from FTP connected file using something like random access to avoid the restart of downloading the file?
"InputStream" does not support "seek"-like methods.

From RFC 959
RESTART (REST)
The argument field represents the server marker at which
file transfer is to be restarted. This command does not
cause file transfer but skips over the file to the specified
data checkpoint. This command shall be immediately followed
by the appropriate FTP service command which shall cause
file transfer to resume.
You should also be aware of RFC 959 Section 3.4.2 on BLOCK MODE transfers which is what allows FTP to REST a connection and "skip" n-bytes of a file.

Connection problem - no ftp connection

It is hard to use Dreamweaver, when the FTP connection seems to have been erased. Has anyone experienced this?

Hello,
many of the people here use the DW integrated FTP function.
There this should work: Site->Manage Sites. Select your site and click Edit. Use wizard on the "How do you connect to your remote server?" question to select FTP. Insert your FTP login information and test the connection. Now you should be able to upload your site. > Look to your files panel. Use Up arrow to upload files to your server. You naturally need all the data here to access the server.
In addition, I'll quote a hint from Nancy O.:
Try toggling Passive and/or Secure FTP on/off.
Your web host might have changed upload requirements to improve security.
Another thing to check is your Anti-virus and Firewall settings. If they are too restrictive, DW may not have permission to connect to the remote server.
Some here have difficulties, so perhaps it is worth to go a different way. It's well known, that in all these cases you describe I'm not a friend of a detailed troubleshooting. To be able to be independent in all this things It is one of the reasons why I prefer an external FTP program. The difficulties with which you have to fight encourage me in this opinion, not least because we always search for experts, we don't charge a "jack of all trades".
To manage several websites or to upload my files and sometimes for the opposite way, for a necessary download from my server or to use a "a site-wide synch", I'm using FileZilla. It simply looks easier for me to keep track of all operations precisely and generate or reflect easily the desired tree structure.
Above all, FileZilla has a feature (translation from my German FileZilla) called "compare file list". Here it's possible to use file size or modification time as a criterion. There is also the possibility to "hide identical files", so that only these files which you want to redact remain visible.
And even if it means you have to install a new program, I am convinced that there is an advantage. Here is the link to get it and where you can read informations about how it works:
http://filezilla-project.org/ and http://wiki.filezilla-project.org/Tutorial#Using_the_site_manager
Mac: Mac OS X (Use: Show additional download options)
http://filezilla-project.org/download.php
Of course, you also need all the access data to reach your server and for MIME issues, you should contact your web host/provider.
Good luck!
Hans-Günter
P.S.
Since I use two screens, the whole thing became even more comfortable.

Adding a site to a ftp connection

Hi,
Just upgraded to DW CS4 and in doing so I pressed a wrong
button...!
I have numerous sites in my site manager window and one I am
working on has reverted to being nothing more than an ftp
connection. This was my fault as I went back into the set-up window
for the site (edit site) and made it an ftp connection only, rather
than a full site with connections to local folders as well as
remote connections.
Problem is, now on the site manager list the icon has changed
from the folder with the name of the site to the ftp//sitename here
icon and I have no idea how to get it back so I have access to my
local folder.
Any help?
Thanks,
SunsV

There really isn't any way to go back from that choice.
so- Make a New site definition and pick "site" and not "RDS"
connection.

How do I get SQL Agent to perform an FTP connection through a SSIS package?

I have created a number of SSIS packages that I am running through SQL Agent in various jobs. I have set up a Credential / Proxy for the job steps and for the most part everything runs no problem. The issue I have is with the step where I make
a connection to a FTP server and download files. In BIDS the step works fine but in SQL Agent the step times out. I presume that it has to do with the account that it is being run under but that is what I thought the Credential / Proxy was supposed
to handle (as it does for all the other steps). I am running on SQL Server 2008 R2. I have created a test job that has only one step which is to connect to the FTP server and download some text files. I have tried utilizing package configuration
files and have tried various ProtectionLevels to no avail.
Anyone have any thoughts or direction for me to take? Will continue to research and will post if I resolve this.
Thanks, Andrew

On the dev environment the ProtectionLevel is set to EncryptSensitiveWithUserKey and that is what I tried first on the prod server. Subsequently I also tried utilizing a package config file (with ProtectionLevel then of DontSaveSensitive) and have
also tried working with the ServerStorage.
For deployment I copied the relevant dtsx files to a solution on the prod server. I verified that the packages all had tested connections in the Connection Manager. I have run all the packages in the BIDS on the prod server and they all worked.
I have created a test package from scratch on the prod server to test the ftp connection. This test package runs from BIDS fine. I have set the SQL Agent file to access through the file system (no luck) and have saved the package to the SSIS Packages
and had the job step access from there (no luck either).

Help with ftp upload problem

Hi I am using a ftp class (known as FTPConnection) that i found on this site: http://www.nsftools.com/tips/JavaFtp.htm , and they only have an example of how to download a File through FTP and not upload one. I am in the proccess of making an FTP upload applet, and need some help on getting upload to work. I also need it to work on both a Pc and mac, so that may be attributing to the problem becuase i am currently on a mac which uses file:// instead of C:\\. Ill post the ftp class, and a snippet of my code that tries to upload a selected file.

ok i tried explaining th eproblem in the previous post, but i apologize if my explanation was poor. anyways, i tried to look into it further by doing a printStackTrace() and believe it may be a read error. here is my new updated snippet, and also a link to a screenshot ([click here for screenshot|http://img143.imageshack.us/my.php?image=picture4qr0.png]) of what the error looks like on my end. it seems like a socket is not being read, or maybe it is initialized properly. Again I apologize if my problem is vague, but I do appreciate your input. thanks.

FTP connection on mobile device works over wifi but fails over 3G

Hi all,
Hoping someone can help, or has come across this issue.
I am developing a mobile app using flash builder 4.6 with the flex 4.6 sdk. My app needs to transfer files via ftp.
The issue I am experiencing is that the ftp connection establishes and files transfer without a problem when connected via wifi, on both android and ios platforms.
However, when only connecting via a 3G connection on a device, a problem occurs. While I can establish a connection, when I send the USER command, I never receive a response.
A simple view with code to reproduce this issue is listed below. Has anyone come across this problem? I have been searching far and wide but cannot find anything related.
Could this be an issue with Adobe Air or the socket class? I have written equivalent code using the android sdk in eclipse, and a connection to the same server and user details works on both wifi and 3g connections.
Any help would be appreciated.
Thanks.

Probably you need to write your own AIR native extension, which uses the native Android sockets..I have the same problem and I'm just starting writing the extension...I guess there is no other way..At least you test with native android socket and you confirm is fine, so we know it should work

FTPs connection error:When using Variable substitution for Directory path

Hi
I am transferring data from BI to xml file via PI: Here a Client proxy from BI sends the data to PI and the PI FTPs the XML file to a remote location. For FTP I am using FTPs SSL connection.
It was working fine untill I used Variable susbstitution to determine Directory path dynamically. I am using this because different xml files are intended to goto the different locations.
I did the variable substitution like this:
Target Message Structure:
---> Target Directory: %var1%
<?xml version="1.0" encoding="UTF-8" ?>
<MT_BI_EXTRACT_FILE>
<Header>
<Directory>/Customer</Directory>
</Header>
<Detail>
</Detail>
</MT_BI_EXTRACT_FILE>
And in the variable substitution I am doing it this way
payload:MT_BI_EXTRACT_FILE,1,Header,1,Directory,1
And the error I am getting is:
Attempt to process file failed with Error when getting an FTP connection from connection pool: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: handshake failure

Does anybody have some Idea of this ??
Regards
Naina

Hi,
I guess the problem is not with Variable Substitution..
Error when getting an FTP connection from connection pool:
So its a connection problem..
Also check the option Disable Security check and try again...
Try to check again if the interface is executing properly without Variable substitution and let us know..

Sender File Adapter - FTP Connection Error 530

Need help!!!
I am getting the following error in XI when I try to connect to an ftp server.
"An error occured while connecting to server xxx.xx.x.xx:xx. The FTP server returned the following error message:'com.sap.aii.adapter.file.FTPEx: 530 Can't open passive connection---(4013)'. For details, contact FTP server vendor"
When I try the FTP connection on the OS level I am able to log in, but through XI I am unable to.
Has anyone seen this error before?

I have seen Error Code 530 earlier, it is typically related to login related issues.
Check if the user mentioned in the Comm Channel has the correct password and read as well as write rights on the Server.
The most likely problem is with the User Credentials or Authorizations
