FTP to SFTP

[Viking]

I have some programs that run FTP scripts to drop off and pick up some files to/from a LINUX server. Suddenly, they (vendor who hosts server) have said they're shutting off FTP and want me to use SFTP (port 22) instead. In my scripts, I don't even specify a port (only an IP address), but I guess it's defaulting to port 21 (?). Anyway, here are a couple examples of simple FTP scripts currently running happily (they are run by CL and RPG programs). What do I need to do in order to have them use SFTP instead? I don't suppose it's as easy as adding :22 to the end of the IP address...?

This one gets a list of files to pick up:

OPEN 'xx.xxx.xxx.xx'
USER myftpuser myftppwd
ASCII
Namefmt 1
SENDEPSV 0
LS (Disk
CLOSE
QUIT

This one picks up a file:

OPEN 'xx.xxx.xxx.xx'
USER myftpuser myftppwd
ASCII
Namefmt 1
SENDEPSV 0
lcd /ecommerce/inbound
GET myfile.csv
RENAME myfile.csv myfile.old
CLOSE
QUIT

This one drops off a file:

OPEN 'xx.xxx.xxx.xx'
USER myftpuser myftppwd
Namefmt 1
SENDEPSV 0
lcd /ecommerce/outbound
MPUT shipments*.csv
CLOSE
QUIT

They just notified me today and want to make the change today... yikes.

Thanks.

You won't get it done today. You've got some work ahead of you.

Start with this information from Scott Klement.

Re: FTP to SFTP

That is a lot of info and looks to completely change the entire approach to picking up and dropping off some files... I didn't understand all that much on first run-through, but much seems to pertain to being a server, doesn't it?

Re: FTP to SFTP

It is not a simple change, especially the first time around. Had a vendor do a similar thing, gave me a week to figure it out. Not sure what you mean by being a server, I guess in that aspect it is similar. You are still the client getting files from their server.

The only similarities between ftp and sftp is the name and some of the commands. If you get desperate you can just use leech ftp and that will connect right up, but that would just make more work for you.

I probably don't understand your question, Viking. The Linux system will still be the server and you'll still be the client.

Contact me thru the contacts page at itjungle.com and I'll give you some more information that might help.

May also want to consider Arpeggio's ARSFTP product, especially if you need to get this done quickly.

It's very easy to set up and use - basically right from a CL program, and they provide sample code.

Cheers,

Re: FTP to SFTP

I was able to do this... I went off of this link...
http://www-01.ibm.com/support/docvie...d=nas8N1012710

My CL program was something like this

qsh        cmd('sftp -b /location/to/script/script.sftp +
             userid@serverip')

In the script I have something like this

cd /location/of/files/                
-mget *.txt /local/file/location/
-mget *.dat /local/file/location/
exit

Then you adapt the CL/RPG code to handle a directory full of files...

Re: FTP to SFTP

That presentation covers a wide variety of topics related to SSH... it's not focused purely on SFTP. It describes how to use the PASE shell, how to setup and run an sshd server, how to use secure copy (scp), how to do interative SSH logons and tunnelling, how to setup digital keys... and finally, it also describes SFTP, etc.

if you're only interested in sftp, maybe you want to skip to slide #31.

There's also more information on my web site than just that presentation. See here:
