Re: Fwd: Neale Ferguson's fsiucv package
The hint is “unexpected return code 15 from connect. IUCV CONNECT (see CP Programming Services) RC 15 is “no authorizations found”. (That’s needed for AF_IUCV sockets, too.) The type of IUCV authorization depends on how the target virtual machine implements security. If the target has a configurable list of users it will talk to, the put IUCV ALLOW in its directory. If it doesn’t have anything like that, then put IUCV in the origin user’s directory.

Mark, Might help if the userid you are trying use in z/VM had ... IUCV ALLOW IUCV ANY PRIORITY in the directory statement for the virtual machine. Our z/VSE-VSEn IUCV driver works with the above statements in the directory for both machines. Have fun!

Re: Fwd: Neale Ferguson's fsiucv package
Hi, Neale. I'm using Ubuntu 20.04 Linux here and there is no "/var/log/messages" file to be found, sorry. I do feel badly about causing you all this extra work, as well, so don't feel you have to get this to work just you me. I have found an alternate method of "talking" IUCV from CMS to z/Linux that works exactly as I want it to, using the AF_IUCV family of socket calls. I've written a simple server that runs on Linux that can be driven by a CMS application using the RXIUCVFN Rexx function package, which is what I wanted to do in the first place. I'll be posting the code and a short "how-to" on GitHub when I can. Take care.
