Conversion from FTP to SFTP
Hi All,
I am using a FTP connection interface...there is a new requirement from one of the customer to have SFTP(SSH FTP)..But the current version of PI i use doesn’t support SFTP….i am looking for alternative approach for making FTP as SFTP.
can any one help me.
Hi Naresh,
Which version of PI are you using?
The new secure connectivity Add-on is available for free.
New ADD-ONs (B2B and SFTP-PGP) for SAP NetWeaver Process Orchestration: Released and Available
You can check OSS note 1695563 to see if your version supports the new SFTP adapter. Maybe if it does not, you can consider upgrading to the latest SP in order to support it.

Hi,
I am using one shell script for file transfer wich is currently using ftp.
Now I have a requirment to use sftp instead of ftp.
Below is the script which is being used for file transfer.....
============================
set -x
#!/bin/sh
# Command line parameters are
# 1- File name
# 2- Host
# 3- User ID
# 4- Password
# 5-Virtual Folder
# 6-Retry Interval
# 7- No of Retries
# 8- FTP result Directory
# 9- MAIL TO ADDRESS
#10- Ascii File Directory
#echo $@ > /tmp/myparams.lst
FILE=$5
HOST=$6
USER=$7
PASSWD=$8
VIRTUAL_FOLDER=$9
RETRY_INTERVAL=10
NUM_RETRIES=3
FTP_RESULT_DIR=/data/tmp
MAIL_TO_ADDR=[email protected]
FILE_DIR=/data/tmp
BASE=" "
I=0
RESULT_DIR="${FTP_RESULT_DIR}"
LOG_DIR="${FTP_RESULT_DIR}/MY_DATA_FILE_SSS.log"
rm MY_DATA_FILE_SSS.log
function connect
ftp -nv $HOST > $LOG_DIR <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
lcd $FILE_DIR
if [ $FILE="MY_DATA_FILE" ] then
quote site recfm=fb
quote site lrecl=111
pwd
put $FILE 'MY_DATA_FILE_SSS'
fi
quit
END_SCRIPT
while [ $I -lt $NUM_RETRIES ]
do
connect
if grep "Transfer complete" $LOG_DIR
then
echo "Success"
exit 0
elif [ $I -lt $NUM_RETRIES ]
then
# echo "Error1"
((I=I+1))
sleep $RETRY_INTERVAL
else
echo "error"
exit 0
fi
done
SUBJECT="FTP to ${HOST} Done"
mailx -s "${SUBJECT}" $MAIL_TO_ADDR < $LOG_DIR
======================================
Can anybody help me to replace the ftp with sftp in this script?
Thanks in Advance,
RoopakIt is not that difficult. The main difference is that sftp uses a different means of authentication. Thus the username and password (and ftp quote ) commands are not relevant.
As for the sftp list of commands - very similar to ftp. I suggest that you try this conversion yourself. Will be a valuable exercise that will increase your knowledge.
The list of commands:
sftp> help
Available commands:
cd path Change remote directory to 'path'
lcd path Change local directory to 'path'
chgrp grp path Change group of file 'path' to 'grp'
chmod mode path Change permissions of file 'path' to 'mode'
chown own path Change owner of file 'path' to 'own'
df [path] Display statistics for current directory or
filesystem containing 'path'
help Display this help text
get remote-path [local-path] Download file
lls [ls-options [path]] Display local directory listing
ln oldpath newpath Symlink remote file
lmkdir path Create local directory
lpwd Print local working directory
ls [path] Display remote directory listing
lumask umask Set local umask to 'umask'
mkdir path Create remote directory
progress Toggle display of progress meter
put local-path [remote-path] Upload file
pwd Display remote working directory
exit Quit sftp
quit Quit sftp
rename oldpath newpath Rename remote file
rmdir path Remove remote directory
rm path Delete remote file
symlink oldpath newpath Symlink remote file
version Show SFTP version
!command Execute 'command' in local shell
! Escape to local shell

Hi,
My application is using ftp to connect to the server. but now it is going to change to sftp. For that I am not able to get what are the things in need to change in my ftp program to make it support for sftp. The following is the ftpbean class and the methods of the class are used by other classes. sftp is already installed and the environment is ready now. but I am not able to proceed where to modify the java..Please help.

How to copy/send text file from FTPS to SAP ECC File Port
Hi Frdns,
I am working on one design, actually my requirement as follows
I am receiving financial information document from Banks, which is in the form of BIA2 message format, it looks like text file. This information needs to be sending to SAP ECC system.
I identified some approaches to full fill the requirement
1)Using Conversion agent/or third party tools to convert BIA2 message in to XML, then using PI I will pick up the XML message, convert it in to IDoc.
2)Without any conversion I will copy the same file (original BIA2 message) in to SAP ECC file port, in this case no conversion required, calling some program I will schedule it.
I am looking forward t implement the second approach because it saves lot of money to my client.
Now I am wondering using File adapter can i copy to SAP ECC File Port or I required ABAP proxy?
What is the best approach to copy the BIA message text file from FTPS to SAP ECC File Port.??
Regards,
RajHi Raja,
>>Now I am wondering using File adapter can i copy to SAP ECC File Port or I required ABAP proxy?
Yes you can do this copy, the only restriction that can happen is the file size.. If you are sure that the fiel will be of few MB at the max then you can use the Configuration part alone and copy it to ECC folder. For doing this you need the following:
1. Sender agreement (mention the sender interface as anything XYZ)
2. Sender communication channel. Pick the file in binary mode
3. Receiver determination (keep both the sender and receiver service as same)
4. Interface Detemiantion (dont specify any mapping and keep the receiver interface name as XYZ)
5. Create receiver agreement (with same service and interface)
6. Use file adapter here

File adapter stops pulling files from ftp
hi,
i defined a communication channel in this way:
adapter type: File
Sender
transport protocol: FTP
message protocol: file content conversion
data connction: passive
connect mode: permanently
Quality of service: exacly once.
somtimes the channel stops working - no indication in message monitioring or communication channel monitoring of any error.
the only way to get it to again and start pulling files again from ftp is to set it to inactive, save, activate, set it to active, save,
activate. somtimes this operation needs to be repeated more than once until it starts working again.
the only relevant note i found is: 999791
https://websmp130.sap-ag.de/sap(bD1oZSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=999791
but this note was already implemented on my system.
Does anyone know what could be the problem?
Thanks,
TomerHi,
In communication channel monitoring, is it so happening that channel is working but it is not fetching any data?
If this is the case, that means, your channel must be getting locked.
For this the solution we have implemented is, in advanced tab, we have mentioned the parameter as 'taskTimeout' and
have assigned the value of 300sec to it.
That means, aftr 300 sec, channel will be unlocked (if at all it is locked) and try to fetch the data again.
If this is not the case with you, then pls explain the issue in detail.

FTPS or SFTP for file scenario. Suggstions
Hi,
I have searched blog in sdn but do not get good blogs/links.
For File scenario which to use FTPS or SFTP.
How to do the configuration in XI and Visual admin.
Full points will be awarded.Hi,
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.
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 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 or' can be triggered from SAP XI through OS command at File adapter level.

Oracle B2B 11g question about pulling data from remote TP sftp server
Hi,
We would like replace our custom b2b solution with oracle b2b, but without resulting much changes in remote TP side. To do that the following issues are to be resolved.
1) in the existing custom b2b, host tp is pulling data from remote TP location. How does oracle b2b pull data from remote location using sftp(AS1 1.1)? Oracle document says that by using global listening channel, we can make oracle b2b listen to the sftp server? Is that correct? Is there any sample about how to configure and test it.
2) For outbound file we would like to preserve the file name. If you use sftp for sending the file out, is it possible to preserve the filename?
3) Some incoming files which are datafiles , does not have any identification pattern. Is there any other way to identify the document type? For example from which location we are pulling the file can tell us the document type.1) in the existing custom b2b, host tp is pulling data from remote TP location. How does oracle b2b pull data from remote location using sftp(AS1 1.1)? Oracle document says that by using global listening channel, we can make oracle b2b listen to the sftp server? Is that correct? Is there any sample about how to configure and test it. I am not sure what do you mean by AS1 1.1 but yes, SFTP is supported in Oracle B2B and if you want to poll a SFTP location, then you need to create a listening channel in Oracle B2B. For creating a listening channel, please refer -
http://download.oracle.com/docs/cd/E14571_01/integration.1111/e10229/bb_listen_chan.htm#BAJJICJJ
2) For outbound file we would like to preserve the file name. If you use sftp for sending the file out, is it possible to preserve the filename?Yes, it is possible. There is a setting "Preserve Filename" in transport protocol parameter of a SFTP channel which should be enabled for this purpose.
3) Some incoming files which are datafiles , does not have any identification pattern. Is there any other way to identify the document type? For example from which location we are pulling the file can tell us the document type. In case of FTP/FILE/SFTP, file name can be used to pass document type and revision information to Oracle B2B. Please refer "Filename format" setting on the above mentioned link.
I figured it out from another thread about how to pull the file. I configured the listening channel so that it reads from a remote server using sftpo protocol. And I have given the filename format as %FROM_PARTY%.dat. I am putting a file like TESTBC.dat. TESTBC is the name of the remote TP. B2B is reading the file but, recognizes the document tupe, but says that FromTP null. What is the solution?
Make sure that TP name is same as what you are giving in filename (cross-check for spelling). You may also try with default naming convention (do not mention anything in Filename format in listening channel configuration) - %FROM_PARTY%_%TIMESTAMP%.dat
for eg -
Acme_12345.dat

Stetting up FTP and SFTP adapters for the same interface
Experts-
I have a situation in which client has a requirement to setup both FTP and SFTP adapters (from adapetive adapters) for the same interface. They want to have a copy of file locally and also want a file to be sent out securly using SFTP. In my interface which was previously developed they have used one business system and added FTP and SFTP to the same. If try to add new Receiver Agreement it will say that the object already exists as the Interface Mapping is same.
Please send me any suggestions which would resolve my problemHi Hari,
As you cannot create two Receiver agreement using only one receiver interface , please create a new receiver Interface, add that in interface determination step and then assing a different channel to new receiver agreement.
If your requirement is to store the file ,i would suggest write the file in your unix directory using NFS( /usr/sap...). then run a AFT job (if already set up in your landscape) to transfer file securly to target destination.Not sure if its feasible in your case otherwise you can use SFTP for the secure transfer.
Best Regards

Apple Remote Desktop vs. FTP vs SFTP vs PC
Complex one this, and its driving me mad - can anyone advise
Background: two small networks in different locations with different ISPs. Both behind routers. All necessary ports opened. The primary objective was to have access between two macs to allow Remote Control and file sharing via FTP or, better still, SFTP (using Transmit). Everything was fine and the Macs could connect to each other everywhich way.
Then I was forced to do a complete reinstall on one of the macs
Current situation: Remote Desktop continues to work fine both ways. The (Intel) Mac with the reinstall will only connect via SFTP (FTP times out). The other Mac will not communicate with the Intel Mac at all with either FTP or SFTP. But the PC alongside it will connect using FTP through the same router
Any clues?Just had some success establishing the SFTP connections in both directions.
Trying to SFTP into the Intel mac here reported a message:

Aug 13 16:03:08 BigMac Fetch 5.2.1 (5C263): Host key verification failed.
I guess the host number changed as a result of the earlier system reinstall
Anyhow, I made hidden files visible using Tinker Tool, found the known_hosts file in the Home/.ssh folder - then deleted its contents on both machines
When I went to log on using SFTP in Fetch, there was a brief "are you sure" king of warning then it connected. This worked in both directions
Still can't get the FTP working in either direction though.
Trying to connect From the Intel to the Mac I get:
Fetch 5.2.1 (5C263): Fetch could not get the file list because data connections were blocked by both a firewall at the server and by the Mac OS X firewall. (Ask the server administrator to allow passive mode data connections through their firewall, or turn off the Mac OS X firewall in the Sharing pane of System Preferences.)
From Mac to Intel I get:
Fetch 5.2.1 (5C263): Fetch could not get the file list because the connection was refused. (Contact the server administrator for more information.)
Logs show that a communication is taking place between the computers, but the ipfw.log shows a "12190 Deny TCP" message -
Getting ÿþ as saved conversations from Lync in Outlook in Office 2013
Hi,
I've been trying to get to the bottom of this and have found similar posts, but no one seems to have an answer.
When I IM someone using Lync 2013, they get a pop up notification but instead of the message they see ÿþ<. Once they open the chat window, they can see my typed text. Occasionally, certain people can't see the first line of my chat, but as
long as they keep the chat window open, they can see everything new I type.
All my conversations that are saved in outlook show ÿþ< for the text and are unreadable. I've disabled the saving of conversations because they have become worthless.
I believe it has to do with BOM but have not been able to find a way to fix this.
If I copy a conversation from the chat window and paste it into Microsoft Word it shows ÿþ<, but if I paste it into notepad the conversation appears.
(I had inserted a screenshot here, but am unable to because I am unable to figure out how to get my account "verified")
I've tried changing the preferred encoding for outgoing messages: to Unicode (UTF-8) in Outlook, but this had no effect and I can't find a similar option in Lync 2013.
(I had inserted a screenshot here, but am unable to because I am unable to figure out how to get my account "verified")
I enabled logging for Lync and the event IDs that come up are 1, 11 and 12, to which I cannot find any information for at the moment.
Any help and or suggestions would be appreciated.Hi,
Did the issue happen only for you or for multiple users?
Please try to delete Lync User Profile and information on Registry, then repair Office 2013.
The path of Lync User Profile: %UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync
The path for information on Registry: HKCU\Software\Microsoft\Office\15.0\Lync\[email protected]
Then test the issue again.
