Open source resource: Secure FTP on 3000
June 24, 2013
Even though FTP won't help much in transferring databases on an HP 3000, a lot of other data can be moved using File Transfer Protocol. The question of how to do this securely using SFTP just came up last week. We've covered the topic before, but a new contributor, Brian Edminster of Applied Technologies, chipped in with some advice and a new resource, built from open source.
The initial question:
I'm trying to use ftp.arpa.sys to FTP a file to a SFTP server and it just hangs. Is there a way to do a secure FTP from the HP 3000?
Brian Edminster replies:
The reason that using MPE's FTP client (ftp.arpa.sys) fails is because as similar as they sound, FTP and SFTP are VERY different animals. Fortunately, there is a SFTP client available for the 3000 -- the byproduct of work by Ken Hirsh and others.
It used to be hosted on Ken's account on Invent3K, but when that server was taken out of service, so was Ken's account. As you've no doubt already noticed, it's available from a number of sources (such as Allegro). I'd like to highlight another source: www.MPE-OpenSource.org
Edminster goes on to explain he administers that site, as well as puts together the 'pre-packaged' install available there. It's in a single store-to-disc file in Reflection 'WRQ' format, making it easy for the majority of sites to retrieve and use. Here's the URL:
I have a customer that's been using SFTP daily as part of their PCI compliance solution for several years. They push and pull data hourly from dozens of Point-of-Sale systems all over the country, and have moved lots of data this way.
The biggest caveat from that customer's implementation is that if you're moving data over a WAN, SFTP seems to be more sensitive to jitter and latency issues than conventional FTP. We ended up having to upgrade a couple of their more anemic 'last mile' circuits to accomodate that.
In all other respects, it’s quite a robust solution, and can be tightly integrated with existing legacy apps. I know; I've done it.
If you have any questions about how to use the pre-packaged install -- or how to get around any limitations you might run into,-- don't hesitate to contact me. I've used this on dozens of systems over the last decade, and have transferred many, many gigabytes of data with it.
