FTP File Server

Howdy. I do produce video and audio for people. I am doing a project now where the clients dont even live in the same town or state. I would like to have a Mac Mini set up in the future where i can put the file on the hard drive and then send a link in an email to the client and then have a link or instructions on there to tell them how to get to the file they are supposed to get. That way i can send multi gig files to them and they can down load them on their own time and i dont have to waste discs and postage mailing things over night. I would need something where they can not acess any of the other files for other clients on there only the ones for them. Does anybody know of such a software or how to do it. I am needing something similar to a Digidelivery server made by Digidesign. http://www.digidesign.com/index.cfm?navid=38&langid=100& Thanks for the help.

You might take a look at GroupLogic's MassTransit. Without spending a lot of time comparing features and workflows, it looks like the closest thing on a Mac to the Digidelivery server. If that's overkill, something like Haxial's KDX might work for you.
For additional suggestions, you might try asking in the Mac OS X 10.4 area, since this really isn't hardware related per se, so you don't want to limit just to Mac mini users.

MDM FTP File Server - SFTP?

Looking into what it takes to install and setup MDM. The Master Guide lists a file server as a required component and states to look at the Configuration guide for details. The Configuration guide talks about the FTP protocol and other guides mention it as the FTP File Server.
Can SFTP be implemented instead of FTP? If not are there options instead of FTP. FTP is not permitted for internal data movements in my environment. I saw in the XI forum that XI with the right SP can handle SFTP with a java proxy.
Thanks

Hello:
That FTP Server was just a way to give MDM the files for import, and take the files as export.
You can use anything you want. The file server could be the MDM server itself. You just have to manage how to give MDM something to import, and what to do with the file that MDM will syndicate
I hope this helps

How set FTP file server set in my Data carriar in DMS

hi

Hi Andreas,
It depends on your needs. If you want to provide redundancy to your FTP services, it is recommended to group two VMs in an Availability Set to ensures that during either a planned or unplanned maintenance event, at least one VM will be
available and meet the 99.95% Azure SLA.
http://azure.microsoft.com/en-us/documentation/articles/virtual-machines-manage-availability/#configure-each-application-tier-into-separate-availability-sets
If you want to set up two files servers in Azure VMs to an availability set, you can follow the steps below:
1. Create a virtual network:
http://azure.microsoft.com/en-us/documentation/articles/create-virtual-network/
2. Create a VM in a new cloud service and choose teh virtual network you have created:
http://azure.microsoft.com/en-us/documentation/articles/virtual-machines-windows-tutorial/
3. After the VM is running, you can create an availability set on the VM in the Configure page of the VM in the managemeng portal.
4. Create a new VM into the same cloud service and add it to the availability set.

Susie

Firefox does not show filesystem or FTP file list

When I type "/" or "file:///" in the address bar it does not show anything. It should list my the folders in my root drive but it shows nothing. Strangely this is the same for any FTP file server I go to. It shows nothing but claims to be loaded. I think something in Firefox is missing.

I cleared the cookies and that might have done it. Comment if you have or had this problem.

Problem in Archiving File From FTP Server to XI File Server Using FCC

Hi,
The scenario is file to IDOc. XI has to read the input file from client FTP server and archive it to XI local file server. Archiving on XI server is working fine without FCC (for xml files). But with FCC, the sender FTP adapter is archiving empty files (0 kb files).
I've checked SXMB_MONI, even there I can see the file data and the IDoc is getting posted with proper data. But, the archived file is empty. Not sure about the problem.
Please suggest. Thanks in advance.
Regards,
Joe.

Hi,
File adapter has the functionality which support the empty file handling.
Handling of Empty Files
Specify how empty files (length 0 bytes) are to be handled.
○ Do Not Create Message
No XI messages are created from empty files.
The files are processed according to the selected Processing Mode.
For example, if the processing mode is Delete, empty files are deleted in the source directory.
○ Process Empty Files
XI messages are created with an empty main payload.
The files are processed according to the selected Processing Mode.
○ Skip Empty Files
No XI messages are created from empty files.
Empty files are skipped and remain in the source directory.

Sending XML file from SAP to Windows Based file server with FTP function

Hi Gurus,
We are using SAP BW 3.0B version.
I need to convert data in ODS to XML format and send this XML file to remote server which is not a SAP application server, it is just a Window Based file server with FTP function..
By writing some ABAP code I have converted ODS data into XML format (which gets saved in my local system)
(Is that I need to put this file in Application Server to send it to the other servers? )
Now the thing is how I can send this file to that Windows Based file server.
plz suggest me.... what can be done......
Thanks in Advance

Edited by: Madhusudhan Raju on Dec 3, 2009 4:25 AM

I dont think the above code support windows OS. Because I always execute this script via UNIX.
I think you can try this option, go to command prompt, goto the destination path where you have an XML file using cd....
ftp (destination servername), specify the username and password.
afterthat, use the command put and filename.
check whether the file had reached destination successfully or not.
For automation purpose, you can use the following script like
ftp: -s: test.txt (servername)
In test.txt,
UserName
Password
bin
cd /files
put file.xml
bye
Also, you can check in SM69, there will be some SAP external commands to automate the file transfer.
Thanks

FTP to file server - file not reached to file server but in XI success

Hi
Scenario is
XI is picking file from SAP and sending to a file server. In XI ,communication channel and sxi_moni shows message transferred successfully.
But the file server guys din't receive any file. Can any one tell where the message can be lost. If file is not reaching destination then how come in XI its showing SUCCESSFUL message.
Regards

Hi,
Your communication channel is not able to connect with the FTP sever.
Check in RWB the communication channel log also user id, password mentioned in communication channel.
Check whether that user has authorization to create file on FTP sever.

NW ftp 550 File Server unavailable

FTP service running on one NW 6.5 sp8 server (//server6) in the tree.
I have rights to all servers in the tree.
All file servers are Netware 6.5 sp8
My home directory and default ftp directory is //server1/data/home/me.
Within an ftp session I can
cd //server2/data/dept
but when I try
cd //server3/data/dept
I get the message "550 File Server unavailable".
I have a department whose home directories and department share are on //server3 and I need to enable ftp to those areas. The only difference I can think of between Server 2 and Server3 is that server3 also runs AFP - does that get in the way of Netware ftp?
How do I troubleshoot the ftp connection to Server3?
TIA
Anthony

Thank you, Andrew, for the continued interest.
I have downloaded and applied the newer nwftpd.nlm, unfortunately it hasn't resolved the problem.
I aslo found TID 10060796 Error: "550 File Server Unavailable" after FTP cd to another server which suggests slp problems. The test suggested does show the problem server in the available novell.bindery services from the server runing nwftpd. Any clues what or how to troublshoot if ths is an SLP problem aslo appreciated.

Need to ftp files(BACS) from Server to Users Local Machine-Urgent

Hello,
I am working on a Oracle HRMS Implementation(11i) and have a requirement wher I need to ftp files (BACS File) from a server to Users Local Machine.
Please let me know any scripts or the way forward to achieve the same using a concurrent program.
Thanks a lot!

That requires the users machine for a ftp server installed and to be "visible" to the conc program server, the first one requiring setup and configure for every client and the second one may be a problem if in different segments or security policies. Another approach may be to generate the files on the server in a known location and from the client create a batch script to connect to that server and retrieve the file(s). You may schedule the program to run at certain hours or use a shortcut so the user can run it on demand

Is it possible to upload large files through FTP to server with iWeb?

Is it possible to upload large files through FTP to server with iWeb like for example with Cyberduck?
I don't need to publish website with files, I just need to upload files on server. Can it be done somehow with iWeb?

Here's some info about FTP...
http://www.iwebformusicians.com/Search-Engine-Optimization/Upload.html
Make sure you are allowed to store files on your server. Most hosting services don't allow anything to be stored that can't be accessed via the internet. Check the fine print!

Issue with Ftp Client / Server using Sockets

I have developed a Ftp Client and a Ftp Server. The client Connects to the Ftp Server and sends files to the ftp server. It is a multi threaded server and can have multiple clients connecting to it.
If a client goes down...the server waits till the client comes up
Similarly the client waits if a server goes down and reconnects when the server is again up and running
i am having a strange issue here. When two clients go down and reconnect to the server...They take a long time to connect and transferring of files takes a long time...
Other wise in all other scenarios the duo work properly.
Any feedback and suggestion about this strange issue from all you java gurus out there will be deeply appreciated.

Please note that this is not an FTP client and server. FTP is defined by a standard IETF protocol and this isn't it.
Then, move the following lines:

dout=new DataOutputStream(ClientSoc.getOutputStream());
System.out.println("FTP Client Connected ...");
System.out.println("External IP of Client ..." + ClientSoc.getInetAddress());
//System.out.println("FTP Client Connected ..."+ClientSoc.getRemoteSocketAddress());from the constructor into the run() method. i.e. don't do anything with the socket in the thread which handles the accept().

IDOC to FTP File - Error : SAP:Stack No receiver agreement found for send

Hello Friends,
I need to configure a senario Idoc to FTP File, Í did required settings in R3 and in PI... , did mapping and configuratino in PI... and when I send my idoc I got error msg in monitor
<SAP:Stack>No receiver agreement found for sender ,BMG_ASN_File_Component to receiver ,GTN_224,http://adis-bmg.de/asn,SI_BMG_ASN</SAP:Stack>
I search the fourm but did not got my answer, me just a bit confused...
In my senario I have having followings:
1. Bussiness System ( RFT : sender R3 system). ( I have define a party and make a connection under Idoc Partner )
2. Bussiness Component ( ZTEST_COMP as on Reciever side is File Server, so I define the reciver as bussiness component )
3. Communicatin Channel
 File with protocol FTP having communicatin component as my Bussiness Component ( reciver ). there I defied the required info for FTP
4. Reciever Determination
 Sender:
 - RFT
 - Idoc-Interface
 - urn:sap-com:document:sap:idoc:messages
 Reciever
 communication party = space
 communicatin component = ZTEST_COMP
 Configure Reciever:
 There I again define the communication component as ( ZTEST_COMP)
5. Interface Determination
 -RFT
 - Idoc-Interface
 - urn:sap-com:document:sap:idoc:messages
 Reviever:
 ZTEST_COMP
and define the mapping which I did in design ( although I have seen some threads where mentioned we dont need maaping in this case ) ?
6. Reciver agrement
sender:
- RFT
Reviver:
- ZTEST_COMP
- SI interface ( SI_BMG_ASN )
- http://test-etc.de/asn
and included my CC for file .....
Now when I send Idoc I got error msg that Reciver is not found : am I dong something wrong ? do I have to defien a bussiness system instead of Bussiness Component ?
Pls suggest...

( I have define a party and make a connection under Idoc Partner
Do you really need a party in your communication? Should it not be a partly-less communication.
In the receiver agreement ensure that you have included the inbound message interface.
communication party = space
No need to give any space.
In the Interface Determination i hope that you have included the receiver meessage interface and then the corresponding Interface Mapping.
If still not works then make some dummy changes and again activate....correspondingly check the cache status of the ID-objects

Abhishek.

Time Capsule as a File Server - to replace existing Airport Extreme

Hi
I have a 4th Gen Airport Extreme connected to my cable modem. I was thinking of getting a 2013 Time Capsule to replace my existing 4th Gen 2009 Airport Extreme, to use for Time Machine Backups and also for storing other files which I can access from anywhere only.
Is Time Capsule just a great wirelsss router and backup device or is it any good as a basic file server / nas drive.
Thanks in advance.
Matt

Is Time Capsule just a great wirelsss router and backup device
Yes, it is that.
is it any good as a basic file server / nas drive.
It is not a good NAS.. primary issue.. no internal backup. No way for the TC to back itself up.
No way for Time Machine to backup a network drive.
It still lacks any proper high speed connections for a second hard drive.. usb2 doesn't cut it.
The tools are poor.. actually almost non-existent. No partitioning.. so mixing backups and data is not a great idea.
See Q3 Pondini. http://pondini.org/TM/Time_Capsule.html
Nothing has changed with this new one.
There are no media servers. no ftp, http, or any other access method for files such as is common to the basic NAS of the world.
To say nothing of rsync and all those kinds of things.
It is still slow to spin up and quick to spin down.. fine for data.. not so great for streaming media.
Remote access can be difficult if you cannot get the TC as the main router in the network.

Run HTTP File Server on Mac OSX Lion Server?

Hello!
I have a Mac Mini running Mac OS X Lion Server.
I would like to be able to host a Web Server that runs within the built in Apache server that allows the transfer of files from Client to Mac Mini HD and vice versa using authentication from Open Directory.
My inspiration is HTTP File Server, or HFS (no, not the Disk Format). This, however, is a Windows Program. It allows a HTTP platform to upload and download files from the HD of the machine it is running from. It comes as a nifty .exe that has everything you need. I'd like something similar but to run on the Mac Server.
Note, the upload and download cannot be done over FTP. It must be using HTTP like HFS does.
At the very least, I'd like a HTTP (Port 80) Web Server that runs within Apache that allows upload and download to the HD.
And at best, authentication using the built in Open Directory credentials. And to make even more secure, HTTPS or SSL.
So it's like iCloud or iWork.com but using my own disk space and credentials.
Predicted End Product:
User visits https://192.168.x.x or https://MyDNSName.dns.com
Greeted with Home Screen (.html or .php)
Clicks login
Has a nice login window to use (probably have to be .php to keep simple)
Logs in using same credentials as they would to logon to Mac Mini locally
Greeted with view of their files in their Directory, e.g.: /Library/Server/Web/HFS/User1 or /Library/Server/Web/HFS/User2, etc
Can choose to download present files
Or upload. Click Upload
Upload window appears. Selects file on Client machine.
Over HTTP, file is uploaded to Host Machine to /Library/Server/Web/HFS/User1
What I'd like to know is what is the easiest way of going about this? Some kind of CMS like Wordpress or software like HFS?
Many thanks,
Clark

I'm a little confused here... what's the requirement for HTTP based transfers vs. traditional file sharing protocols such as AFP?
Secondly, how does 'HFS' differ from any other HTTP form-based uploader? Any web CGI or scripting system such as PHP or Perl could easily present an upload form.
Have you considered WebDAV, which is designed as s file transfer protocol over HTTP?
It integrates at the Finder level, meaning you can copy files by simply dragging and dropping file (and folder) icons in the desktop, just like on a local drive. It's part of the standard Mac OS X Apache installation, too.
