Greetings,

This is about FTPing from an AS/400 (aka iBMi, iSeries, Power6, etc.) to Port(990) - aka - SFTP - Secure FTP.

Receiving an error when switching to a new target FTP site that requires using port 990. "-23 Certificate is not signed by a trusted certificate authority."

Need to know how to get around this error...
Anybody else solved this problem already...?

The target server is inside of our network. They're asking us to switch from one server that is not using SSL, to a Linux server using SSL, and they require using port (990)...

I went through the exercise of setting up SSL for our 5250 emulation last year, so I've had some OJT with the DCM interface.

The Linux server can't export a certificate that I can load into our iSeries, and I don't see any way to add a trusted CA to our *System, or Local Certificate Store...

I could be way off base here, so, I'm hoping for an SME who has been down this road...

Some similar posts indicated that IBM sent them a file for them to load into their Certificate Store, or something like that, but I have not tried to open a ticket with IBM yet... I'd rather ask the audience before I run that gauntlet...!

Thanks,
Jeff

There is a lengthy discussion on this site on the topic HERE. IT may be old but the basics are probably the same started in 2009 but active through 2017..
