With your advice I found 1/2 the solution. The OSER_FIRET
variable was missing from opensipsctlrc, which seems to describe
where the reply FIFO should be opened. I had it set to OSIPS_FIRET,
figuring that OpenSER names were no longer being used.

...so using opensipsctl(1) now works (1/2 the problem.)

But even after placing OSER_FIRET in osipsconsolerc, the
osipsconsole(1) still hangs when calling 'ul show --brief':

  Dec 10 10:51:32 name.host.tld <error> opensips[17625]: ERROR:mi_fifo:mi_open_reply_pipe: open error (/pfx/var/opensips/fifo_reply): No such file or directory
  Dec 10 10:51:32 name.host.tld <error> opensips[17625]: ERROR:mi_fifo:mi_fifo_server: cannot open reply pipe /pfx/var/opensips/fifo_reply

Looking in the perl file 'osipsconsole' I see that 'fifo_reply' is
hardcoded to a variable simply called 'name', which is impossible to
debug because 'name' is used everywhere in the perl modules.

Do you happen to know how to set the 'fifo_reply' name and path in
the osipsconsolerc? Are these really hard coded?
