VRF and FTP Server

I have a weird problem with VRF and FTP Server. I have a lab setup whereby two VRFs Client1 and Client2 are created. Both the VRFs are in the same subnet. I have configured FTP-Server and TFTP-Server on this router. TFTP-Server works perfectly fine from both the networks. But for FTP-Server, I can login in to the FTP Server and authenticate positively. But when I try to do listing of directory, it gives a error "can't bind data".
The web access to this router also works perfectly fine.
Any idea why FTP fails.
Before configuring vrf, the FTP server did work fine.
Any idea why. here's the config :
interface FastEthernet0/0.371
description Client1
encapsulation dot1Q 371
ip vrf forwarding client1
ip address 10.0.1.1 255.255.255.0
interface FastEthernet0/0.372
description Client2
encapsulation dot1Q 372
ip vrf forwarding client2
ip address 10.0.1.1 255.255.255.0

Ohhhhhhhh!!!
I'm even more convinced its a passive/active problem with the ftp control channel. Did you try the gentleman's suggestion of passive ftp?? What's happening is that from a client on one vrf, you're attempting to terminate the ftp session in a router whom is in the second vrf. The ftp data session isn't vrf-aware from the sound of it, hence my question about what device models and IOS you're using.
But I agree, it's getting complicated enough that sounds like TAC-time. My bet is something isn't vrf-aware to the point that the data is lost. For instance, to ping from one device to another from _within_ a vrf router instance, you have to use the keyword "vrf" like "ping vrf VRF_Name src dest".
In your situation, your source is on one vrf while the destination is _within_ the second vrf, not just simply the IP packet being routed from vrf1-client (like a Windows PC) to vrf2-server (like a Unix ftp server).
I'd be interested in hearing their solution.

Web host, mail server and FTP.

Dear all:
I have some questions and will try to make my post a short one (although the questions aren't exactly simple). I have the need to set up my own web server, e-mail server and FTP server. It is my understanding (and I remember setting another computer I had 2 or 3 years ago this way) that OS X can be used for this without the need to have OS X server installed. I don't need (at least not for the for the immediate future) to have a server for my own local network. Basically all I need is a single computer where (1) I can host multiple web sites, (2) I can host my own e-mail that will correspond in number to the number of web sites (domain names) being hosted and (3) I can set-up as a FTP server so that my clients can log on and download files.
I have used VirtualHostX for virtual hosting as well as PureFTD Manager with good results in the past. I've also found both to be easy to use, with a good and intuitive GUI which is essential for someone with as little knowledge as I have of networking. My question now as to do with e-mail and how to set-up Mac OS X to work as an e-mail server.
Are there any applications you would suggest that would be simple to use, have a simple and intuitive user interface and also provide mailing list services along with e-mail services that you would recommend ? I've looked at a few but most of the ones I have found seem to require command line input and this is something I am not comfortable with. I need an application with a simple interface and allows things to be set-up in a straight forward manner (and preferably free instead of paid).
What would be your recommendations for this project ? Any recommendations, advice and suggestions you can offer will be very appreciated.
Thank you in advance,
Joseph

Perhaps you should give people more time to answer.
1. You do not need a DNS on your server, ask the ISP to set up the MX record as they set up the A record.
2. Not really enough information in your setup to say either way, but as it takes seconds to do and you have everything else needed - set it up anyway.
3. Domain name: mydomain.com, Host name depends what you call it. If you don't have a name why not mail.mydomain.com and make you mx record point to that name. Perhaps that is what your A record is already.

SAP XI support SFTP and FTPS?

Hi Gurus,
I would like to find out if SAP XI supports both SFTP and FTPS. If yes, how do I perform the configuration?
Thanks in advance.

Business Case:
In many implementations Business requirement is to "secure" the file/data transfer between XI and any third-party system. So there is a need of secured connection between XI/PI and any file based third-party legacy systems.
Following solutions are proposed to cater secure connection between XI/PI and any third party systems.
1) SFTP (Secure File Transfer Protocol)
"SSH File Transfer Protocol" or SFTP is a network protocol that provides file transfer and manipulation functionality over any reliable data stream. It is typically used with the SSH-2 protocol to provide secure file transfer. SFTP encrypts the session, preventing the casual detection of username, password or anything that is being transmitted. One key benefit to SFTP is its ability to handle multiple secure file transfers over a single encrypted pipe. By using a single encrypted pipe, there are fewer holes in the corporate firewall.
2) FTPS (FTP over SSL)
FTPS (FTP-SSL) is a real ftp that uses TSL/SSL to encrypt the control session and if required the data session. With FTPS, the control session is always encrypted, but the data session may not be always encrypted. FTPS is a file transport layer on top of SSL. SSL, or Secure Sockets Layer, is a method by which an encrypted u2018pipe' or tunnel is established between the FTP client and FTP server. Once the secure tunnel has been established (which is done using 128-bit encryption techniques), standard FTP is used to transfer data over the secure connection.
Feasibility of SFTP and FTPS in XI:
SFTP:
As per the latest SAP PI/XI support pack, it does not support SFTP via File Adapter.
So alternative approach to cater this requirement from XI is to make use of Unix Script at OS level to transfer the files from/to third-party systems.
Inbound Interface - i.e. third-party system ->XI->SAP:
File is transferred to a folder in SAP XI landscape from the third-party legacy system using UNIX Script with secured protocol. Once the file is ready in the XI landscape, File Adapter will poll this directory and file is picked up by NFS protocol.
Outbound Interface u2013 i.e. SAP->XI->third-party system:
XI is responsible for writing a file into a folder in the XI landscape. These files are transferred to the third-party system by executing UNIX scripts with secured protocol i.e. via sFTP.
Pre-Requisites:
Public key should be exchanged between external systems and the PI system.
UNIX shell script has to be developed and scheduled.
Advantages:
Highly Secured.
Ability to handle multiple secure file transfers over a single encrypted pipe .By using a single encrypted pipe, there are fewer holes in the corporate firewall.
Disadvantages:
Two-Step process i.e. XI>Temporary folder>External System and vice-versa
Files have to be temporarily stored in XI server.
Multiple failure points i.e. XI and Unix script execution
Maintenance of an external UNIX script.
Difficulty in monitoring the execution of the shell script as it cannot be monitored thru XI.
Need to generate keys and install it in the SFTP site as a pre-requisite i.e. SFTP clients must install keys on the server.
SFTP uses keys rather than certificates. This means that it can't take advantage of the "chains of trust" paradigm facilitated through Certificate Authorities.
Files from the XI server should be deleted/archived in a periodic manner to increase the disc space so that it will increase the performance.
Note: UNIX shell Script can be executed as a background job u2018or' can be triggered from SAP XI through OS command at File adapter level.
FTPS (File Transfer Protocol Using SSL/TLS):
This is a built-in feature of File adapter in XI. But SAP Java Cryptographic Toolkit must be deployed as a prerequisite. (Refer to note https://service.sap.com/sap/support/notes/821267 Question 28). By default following ports are used:
Implict FTPs 990 (Control) and 989 (Data)
Explicit FTPs 21 (Control) and 20 (Data)
Both use cases can be combined with active and passive mode.
Advantages:
Direct transfer of files to/from third-party systems. It is not required to store the files in the XI server temporarily.
Built-In feature from XI File adapter
No extra effort in development and maintenance of Unix Script.
Centralized Monitoring tool from XI
FTPS uses certificates and therefore can take advantage of "chains of trust" paradigm facilitated through Certificate Authorities. This paradigm makes it possible for two entities to establish a trust relationship without directly exchanging security information, which is important for some applications.
Disadvantages:
Requires opening multiple ports forenabling SSLin the firewall. So there are multiple holes in the corporate firewall.
Not every FTP server supports FTPS and many that do, require a configuration change to activate the FTPS protocol extension.
Cryptographic toolkit should be installed in XI system though it is not very complex or expensive.
Conclusion:
Though SFTP seems more secure as it works through one port, FTPS is easier to configure, monitor and maintain from XI point of view. However, the decision depends on many parameters like, cost/effort, flexibility in use, ease of maintenance, company security policy, failure possibilities etc.

Three questions about Java and Ftp

Hello, i've the following questions about Java and Ftp:
1- .netrc file is in $HOME directory but i can't access to this directory from java code. The following line producesan Exception (directory doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");
2- .netrc file must have the following permissions: -rw- --- --- but when i create the .netrc file the following permissions are on default: -rw- r-- r--, how can i change this permissions? (In java code, i can't use chmod.....)
3- Are there any way to pass parameters to a .netrc file? If i get to do this i needn't change the permissions because i can't modify or create/destroy this file.
Thanks in advanced!!!
Kike

1- .netrc file is in $HOME directory but i can't
access to this directory from java code. The
following line producesan Exception (directory
doesn't exists)
FileWriter file = new FileWriter ("$HOME/.netrc");$HOME would have to be replaced by a shell, I don't
think you can use it as part of a legal path.
Instead, use System.getProperty("user.home");
Ok, thanks
2- .netrc file must have the followingpermissions:
-rw- --- --- but when i create the .netrc file the
following permissions are on default: -rw- r--r--,
how can i change this permissions? (In java code,i
can't use chmod.....)Yes, you can: Runtime.exec("chmod ...");
I need to use estrictly the .netrc with -rw- --- --- permissions
Yes, i can use Runtime.exec ("chmod ..."); but i don't like very much this solution because is a slow solution, am i right?
3- Are there any way to pass parameters to a.netrc
file? If i get to do this i needn't change the
permissions because i can't modify orcreate/destroy
this file.I don't think so. Why do you need the .netrc file in
Java at all? Writing a GUI frontend?I want to use automatic ftp in a java program and FTP server, the files and path are not always the same, so i can:
- modify .netrc (for me is the complex option)
- destroy and create a new .netrc (is easier but i have permissions problem)
- use .netrc with parameters but i haven't found any help about it
Thanks for your prompt reply!!!!

How to set up a FTP and web server and integrate with DMM 5.2

Hi All ...
I need to set up a external server only for content publishing to reduce the overhead of the DMM server .
can anyone guide me on how to set up the external server and intergrate it with the DMM 5.2
Thanks

semuthu,
Notes from the Release Notes:
Compatibility Limitations with Microsoft Internet Information Server (IIS)
DMPs that use firmware release 5.2 are compatible with only one version of Microsoft Internet Information Server.
That supported version is IIS 6.0 for Windows 2003 Enterprise. If you do not have the supported IIS version but
want your DMPs to retrieve assets from a webserver, we recommend that you use Apache instead of IIS.
I would suggest using Apache instead of IIS for the webserver service. IIS can be used as FTP if needed.
There are plenty of Documents on the Web about setting up Apache and FTP for servers.

http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch20_:_The_Apache_Web_Server
Once the Webserver is setup and operational. You simply store your media content on the Webserver
and then have your DMS assets in the media library use an external URL address for its location.
If you want to use external server for other features in the DMM, you can can see how to configure

FTP and DHCP Server on Windows Server 2012

Our company recently bought several Dell Wyse R10L Devices from another company. We can use these to make remote connections to a remote server but we have a problem when we use two monitors. The picture stretches across two monitors. On the official Wyse
Forum I found a way to resolve the problem. The only ist to connect the Wyse device to an FTP Server from where the Wyse can pull its configuration from an ini file. The FTP Server also needs to be connected to a DHCP Sever. I am newby and I don't have much
experience with servers. Is there a detailed manual for connecting the Wyse device (it uses ThinOS) to a FTP Server.
Kind regards

Hi ivicapro1987,

Export Table to flat file and upload to FTP server for external vendor

I have done some extensive searches on the forums and I think I have an idea but really need some help. Basically have a table that needs to be exported to a flat file and uploaded to a FTP server so that our vendor can get the data Monday-Saturday and automated by sysdate. This data is used to produce daily letters that go out to customers.
After doing some searching I came across the UTL_FILE package and reading more into this right now but I am not sure if it is what I should be using to create the file.
I am using TOAD right now and can see how to do it manually however really need the file to create itself and send automatically at 6 am Monday - Saturday with the date at the end of the file name making it a unique file for each day.
Thanks in advance for all of your help.

As Justin and others have mentioned I wrote [XUTL_FTP|http://www.chrispoole.co.uk/apps/xutlftp.htm] so you wont find it in the Oracle documentation. It's pure PL/SQL and uses UTL_TCP and implements an integrated PL/SQL FTP client / API. One of it's many overloaded procedures FTP's the contents of a refcursor straight to a FTP server of your choice, meaning no intervening file is required. Since it is pure PL/SQL, it is trivial to schedule using DBMS_JOB/DBMS_SCHEDULER.
Any questions just ask.

Loading and exporting files to FTP server

Hi gurus,
I need to import and then export my files to the FTP location. I have my files kept at application server level.
But when I try to import or export any file through BPC Excel, It gives me the path of my desktop only.
So my question is ,
1. Do I need to specify the directory of FTP location somewhere?
2. How to use the package - Import files from FTP. And what should be the URL of file kept at FTP location.
Thanks .
Sanjay

Hi. In data manager, you should be able to just type or enter the URL for the FTP site manually, for example ftp://host/documents/ As for aplpliation server, you should be able to simply enter the file path manually, for example
<appserver>\usr\sap\documents\
Data mananger does not currectly support browsing to the application server, but it will accept the location in the prompt.
Also, keep in mind that the FTP server must be inside your corporate network. This is a limitation of the functions used at the NetWeaver level.

Rich Heilman

Rename and move files on remote FTP server

Hello,
We have a scenario where XI transfers a file to a remote FTP server at partner end using File Receiver Communication channel.
These files are huge,so there is a risk of picking up incomplete files at their end when XI is still writing the file on their server.
Hence,we have decided to follow the approach which is already mentioned a number of times on SDN that XI would place a file with different name and in a different folder on partner's FTP server.
This would then be renamed and moved to the required folder on the same server.
This could easily be managed using a script at partner end but there are some problems when they are not able to do this.
Is there a possibility to achieve this using 'Run OS command after Message Processing' in XI when Source and target folders both are on partner's FTP server?
If yes,can anybody please provide code for such a script and corresponding setting for this parameter in XI Communication channel?
Thanks a lot in advance.
Best Regards,
Shweta

Hello,
Thanks for the reply.
But this has to be done in FTP session because the source and target directory both are on remote FTP server.
Instead,in SAP documentation,I found a parameter :
ftp.putSafe=YES|NO
Use this specification to define whether a transferred file is first created with a temporary name and only renamed once the transfer is complete (YES), or whether it is created with its final name at the start of the transfer (NO). The latter case can lead to problems if an application on the FTP server accesses the file before the transfer is complete. If you specify YES, this problem is avoided because the file only becomes visible with the search name when the transfer is complete.
The default value is NO.
Doesn't it serve the same purpose?Do we still need to write scripts?
I have tried to include this in Additional Parameters in Advanced Mode as:
ftp.putSafe YES
but I can't check in test system whether it is really working or not.I would like to confirm if it helps.
First of all,I would like to know if this setting works for XI3.0 SP17.
Can anyone please help.
Thanks.
Regards,
Shweta
