Using FTP port 21

I have a WRT54G2 router. I recently got a LaCie network hard drive that uses remote access (FTP) to access the hard drive. I have connected & transferred files locally but have not been able to connect remotely. LaCie support tells me that I need to get port 21 open on my router. I am not sure exactly how to do that. I have contacted my ISP (at&t) & they do not block port 21 or anything to do with FTP. Thanks so much, I'm fairly new at this stuff.

First of all, I would STRONGLY advise not opening port 21 on your router, unless you are going to do it temporarily for times you want to transfer files. Opening FTP (port 21) is like opening the door for hackers. You may find your bandwidth being used by people trying to gain access to your system....
If you MUST do it, make sure the FTP server on the network drive is secure...thoroughly research the device on community bulletin boards to find out if there any known vulnerabilities that cannot be overcome. If you STILL want to go ahead, make sure you configure it with a very strong password, that is unlikely to be cracked...there are numerous sites out there that can help you to pick a strong password.
If your FTP server in the device supports it, and you know the IP address from which you will be accessing it, see if you can restrict FTP access to only your loacal network, and any specific IPs you will be accessing it from.
Then, once you have finally decided you want to potentially allow the world to access your files, go to portforward.com, where you can find out how to set up port forwarding (opening ports) on your router.

Changing Application that uses FTP port 21

We have a Windows server that uses an OCR software that allows our printers to scan documents to our Mountain Lion server to a document management application (at least thats what we are trying to do). The problem is that the OCR software is sending it to an FTP share but will not let you specify the FTP port number. By default Mac uses port 21 and I know how to change that port to something else. I just need to know if there is a way to let another application take control of port 21?

Sure. Shut off the ftp server on the target system.
At most there can be one application listening to a particular TCP port. If you don't want that to be ftp, shut it off.
But I'd tend to doubt that'll help, here.
I'd be interested in learning a little more about how this OCR tool works and how this file transfer supposedly happens, as ftp is a paragon of insecurity and also largely incompatible with modern network security and firewalls, but this particular request for a changed-port seems quite unexpected.
The identity of the OCR software might help, as a look at the documentation would be interesting, too.

Is there any API's for providing FTP using ssh port.

Currently we are having a requirement to FTP files only using ssh port(Secure FTP). Can anyone please suggest me an API which provides the FTP'ing operation using SSH port.

I am currently using a Sinetfactory thirdparty package from JScape for the Secure FTP functionality(FTP over SSH). But Sinetfactory package tranfer rate is much slower than the manual sftp(command-line run in linux server for manual ftp using ssh).
Since it is very slower than ordinary sftp(ftp over ssh), I thought of using other thirdparty FTP package which supports FTP using ssh port. Can anyone please suggest me a thirdparty package which will has the sftp functionality and with better transfer rate.

How do I set up my Belkin router to forward ftp port to macMini?

I am trying to set up my spare macMini (non-intel) as an ftp server, but I am not able to connect to the ftp server (office) from a remote location with my MacBook Pro (home). I have tried to make the right settings as below:
1. forwarded ports 20 and 21 on my Belkin router to the private IP of my macMini (192.168.2.15)
2. set up a dynamic dns account xxx.dyndns.org so that this domain is updated with the current public IP
3. set Sharing Preferences to allow ftp access and turned off the Firewall
I think the port forwarding info is not correct because it does connect if I use the DMZ setting and hard code the public IP to the private IP.
Any help appreciated,
Cynthia

Are you sure that your Internet Service Provider (ISP) doesn't block the ftp ports?
Is is fairly common these days for ISPs not to allow any kind of file server on ordinary household contracts.
Anyway, I'd suggest you rule that out before you get further into the intricacies of port forwarding.
I also hope that you only have the firewall turned off for the ftp ports -- or if not, that your router has firewall protection.

How to use FTPS using FTP adapter

I am trying to create one BPEL process using SOA 11g 11.1.1.4, which will put file on remote location using ftp adapter. I have created JNDI properly and using wallet.
useFtps= True
walletLocation= correct path of wallet created in Oracle HTTP Server(OHS)
walletPassword = walletPassword
host = ipaddress
username = myUsername
password = myPassword
For all this I have followed http://download.oracle.com/docs/cd/E17904_01/integration.1111/e10231/adptr_file.htm#BABEBGGD
Now, whenever I try to test that BPEL process it gives me error:
"Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'Put' failed due to: Error in establishing SSL session. Error in establishing SSL session. Unable to establish SSL session on control channel. Reply String: 530 Please login with USER and PASS. Reply Code: 530) Please correct the setup for SSL. ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution"
Any suggestion or resolutions are welcome.
Thanks!!

Hi,
When you configure the Connection Factory for FTP Adapter in Admin Console, provide the following values for the attributes like the hostname, username, password, port and the path of remote location as where
you want to write the file in remote Server i.e., ftpAbsolutePathBegin. Please fill this
attribute with the path like /soa/ftp/file (example path). If you are writing to a remote FTP server you need to create a Connection factory for that as above.
Please try this and let me know...
Thanks,

Use FTP Transport Protocol (XI) to send text file created from R3

I've configured a Port in IDoc Processing (WE21) to create an output file from a Bank Partner Profile (WE20) where my Message Type is PAYEXT and IDoc Type PEXR2002.
I need to take this Text File and send it to the Bank;s FTP site using the Integration Server (XI).
How can I take this text file and simply send it to the Bank without going through File Content Conversion in order to convert it to XML as the Sender and then uncovert it during the Receiver to FTP the file to the Bank?
If that is not possible, would anyone know how to configure the RecordSet Structure and parameters for both the Sender and Receiver?

Hi,
Let me re-phrase your scenario:
ECC is required to send PAYEXT IDOC to XI which needs to be send to the bank in IDOC text file format to the bank. If this is the case we can achieve this by doing the following:
1.Rather than using TRFC port used by the IDOC as the method of communication, you can leverage using file port. The configurations to the file port are simple. You need to select a place where you can drop the IDOC file created by the ECC system and XI would pick up the file.
2. Poll for the file using NFS from that particular location where ECC drops the file. (If it is being staged on the ECC system, then XI service user SAPservice<SID> must have access permission on that folder like \usr\sap\put\interfaces.
3. Configure receiver FTP adapter to send the file to the bank.
Hope this helps.

Duplicate File issue using FTP adapter - BizTalk 2010

Hi We encountered an Issue of picking Duplicate files in BizTalk 2010 from the FTP Location. Need your assistance on this.
Mainframe sends multiple files a 0 KB file to FTP and BizTalk picks during a particular service window using FTP Adapter.
Receive Location has a pipeline component which decodes the MF file(EBCDICRow format).
Send Port transmits the file which is decoded in the Receive location. There is no mapping or orchestration involved.
When 2 files are placed in FTP Location. BizTalk Transmits the files successfully
No suspended messages in BizTalk but we see below error in event log. we tried reproduce the issue but no luck.

Hi Sri,
There could be two reason for such a behavior:
1) Using Non-Clustered Hosts: It is always recommended to use the clustered host for FTP adapter. Because FTP don't allow
any locking mechanism on the files so in case of non-clustered with multiple host instances you might receive same file multiple times through different host instances.
2) If the original document is still being written to the FTP server by the host application, the FTP adapter cannot
delete the document and will retrieve another copy of the document at the next polling interval that is configured for the receive location. This behavior causes document duplication to occur.
Workaround could be:
Configure the host application to write to a temporary folder on the same hard disk as the public FTP folder and to periodically move the contents of the temporary folder
to the FTP folder. The temporary folder should be on the same hard disk as the public FTP folder to make sure that the move operation is atomic. An atomic operation is an operation that is functionally indivisible. If you write data to the public FTP folder
by using the BizTalk Server FTP adapter, you can do this by specifying a Temporary Folder property in the FTP Transport Properties dialog box when you configure a send port. If you specify a Temporary Folder property, make sure that this folder is on the same
physical disk as the public FTP folder.
Configure the FTP receive location to operate within a service window when the host application is not writing data to the FTP server. You can specify the service window
when you configure the receive location properties.

How to call serlvet using ftp protocal

Hai,
How to call servlet using ftp protocal . if any one having please send that program . because generic servlet will receive any protocal request .

The basics are to have your Server listen to port 21.
You would then have to parse the request information to determine what is being asked for and generate an appropriate response.

Should FTP port be opened for client_to_as function

I need to transfer a file from the client machine to the Solaris Server where the 10g forms are running. I was planning on using the webutil_file_transfer.client_to_as function. I know we have to set some properties in the webutil.cfg file. Other than that, should the FTP port be open on the server for the file to be transferred from the client machine. Basically, wanted to know if FTP protocols are used to transfer the file so that certain securities can be set on the server.
Also does anyone know how to delete the file on the solaris server programmatically through Oracle Forms? After the file is transferred from the client to the server and processed, I need to delete the file. I am assuming you can use the HOST command, but not sure of the exact syntax and what permissions are required to delete the file from the client machine.

I have never used the "Client_To_AS" method, however, according to the documentation all you need to configure is the webutil.cfg and insure the transfer.appsrv.enabled parameter is set to TRUE and if the transfer.appsrv.accessControl parameter is set to TRUE then you also need to ensure the target directory on the App Server is listed in the transfer.appsrv.write list. There is no mention that FTP must be enabled on the App Server.
The documentation also states that you should call the WebUtil_File_Transfer.IsASWritable function with the target file name to ensure you are able to write to the file location on the server.
As to how to delete a file, you can use the "rm <filename>" command in Solaris to remove the file. Also, here is the link to the documentation I used to reply to your post.

Two FTP ports on a single solaris server

can i have two FTP ports on single Solaris server ? If yes, HOW ??

Hi adiyakiran,
This is possible in third party ftp server wu-ftpd. you can download it from http://www.sunfreeware.com.
read wu-ftpd faq URL: http://www.wu-ftpd.org/wu-ftpd-faq.html
Testing on a different port number then ftp:21
This can be done from the command line or with a special definition in /etc/services ,/etc/inetd.conf. For command-line, look up -P and -p in the ftpaccess(5) manpage.
To set up with special definitions, add 2 ports with consecutive numbers in /etc/services, and then start wu-ftpd on these ports. Add to /etc/services something like :
ftptest 4021/tcp #command port
ftptest-data 4020/tcp #data port
Then start wu-ftpd from /etc/inetd.conf like :
ftptest stream tcp nowait root /usr/etc/in.ftpd in.ftpd
The key is the name 'ftptest' which associates the port assignment in the /etc/services file to that in the inetd.conf file. Make certain the choice of ports in /etc/services (4021 and 4020 above) are from the local use list and don't conflict with other port assignments (see RFC1700, ASSIGNED NUMBERS). One important subtlety. The data
port is not really derived from the data port declaration in the /etc/services file. The FTP specification (RFC765) states the data port is defined as one less than the command port. However, including the data port declaration in the /etc/services file prevents it from being accidentally assigned to something else.
Thanks.

Arch/Pacman FTP ports

Does anyone know what ports you need to have open in the outbound direction when using pacman.
For example - on my adsl router (with builtin firewall) I typically drop all outbound conections in combination with explicitly allowing connections out to ports 20, 21, 53, 80, 443, 873 etc etc.....
Now - I can't get pacman to connect out using this configuration so I've had to temporarily allow all outbound connections through my rouiters firewall while configuring Arch and sure enough pacman now connects out and I can download arch packages.
So am just wondering, does Arch/Pacman use any "strange" ftp ports by any freak chance- not sure whether it's an issue with the active/passive thing or what - anyone have any ideas?
Thanks.

You can also use wget to download the packages instead of pacman's internal downloader. You need to uncomment the " XferCommand" line in /etc/pacman.conf
It might work in your case.

Detecting an event at ftp port

Hello,
I am writing a program that is supposed to detect when a file has arrived through an ftp port to a certain folder, and process it upon detection.
Would it be appropriate to use a SocketServer on port 21 for this scenario?
If not, do you have any pointers which way to go?
TIA,
Selma

Nope.
If an FTP server is running on a computer on port 21, you will not be able to create a ServerSocket on that port (since it's already in use). Operating systems limit one thing listening per port. That's the way they are intended to work.
As for an alternative solution...
You can get a directory listing every x minutes and check for differences.... shrug
Maybe other people have better solutions.
