XI3.0 Secure FTP in both directions

[Former Member]

Hi!

We have an XI 3.0 system running behind the firewall of the DMZ. Our XI scenarios require to automatically:

- pull files from FTP servers standing in the internet

- push files to FTP servers standing in the internet

in a way that is as secure as possible, because the data to be transferred are critical and confidential.

And all that should happen completely automated without any human intervention (except for the case of problems).

As far as I know XI 3.0 does not support SFTP and additionally we do not want to open any direct channel between the XI and the "rest of the world".

Therefore I think we need some kind of software running in the DMZ that automatically handles the file transfers between our XI and the world outside - ideally it should also be possible that the XI FTP Adapter can be used to trigger automated data transfers.

Has anybody some kind of experience concerning our challenge. If you reply to this posting please take in mind that I am NOT a security expert but only a stupid XI consultant.

Thanx for any hints!

Volker

Hi Volker,

My 5 cents (with michal's 5 you already have 10).

The only way is as michal says. If where is no standard solution, then you have to develop.

For an Java guy should be quite easy to develop the java proxy.

Hope that my comment also helps you to make the decission.

hi,

what do you expect?

it's not XI standard so you have to do it on your own:

create java proxy

create your own adapter

or buy adapter

that's all

Hi,

in one of our projects we did something like this:

XI - SFTP

but we had to program it in java

(java proxy with www for configuration)

there's no standard way unless you'd find

a solution which could be started by

an operation system command from FTP adapter

and do what you want - SFTP transfer

you cna always try some of the third party

xi adapters:

Hi Michal!

Thanx for your reply, but what we are looking for is some kind of an out-of-the-box solution.

To be honest: For us the third party adapter solutions are too expensive in comparision to what we want to achieve.

Hi Volker,

for our client it was too:)

that's why we created the proxy

(but it's not out of the box but a simple java proxy)

just create a java proxy that will handle

the sftp - a few days + testing and you'll have it done
