I have a feeling that this is not a standard operating system.
I was a little puzzled by that myself. It's Solaris 10 x86 running on a pretty substantial box, it shouldn't be an OS limitation. >> babylon4:root:/opt/nut:26 # bin/upsc toka...@localhost >> Error: Connection failure: Connection refused > > For whatever reason, you can't connect to localhost.

Nope, this is not a client OS or vhost. This is the global zone of a Solaris 10 machine, and as you can see, the above was running as root. BTW, upsd.conf is default with everything commented out, which should result in listening on everything: # This defaults to the global IPv4 listening address and port 3493. You # may specify each interface you want upsd to listen on for connections, # optionally with a port number. Despite the above statement, this *actually* results in upsd defaulting to listening only on loopback. I just tried explicitly adding the machine's external IP as well: LISTEN 127.0.0.1 3493 LISTEN 10.24.32.14 3493 babylon4:root:/opt/nut:42 # sbin/upsd -DDD Network UPS Tools upsd 2.4.1 listen_add: added 127.0.0.1:3493 listen_add: added 10.24.32.14:3493 setuptcp: try to bind to 10.24.32.14 port 3493 listening on 10.24.32.14 port 3493 setuptcp: try to bind to 127.0.0.1 port 3493 listening on 127.0.0.1 port 3493 Connected to UPS [tokamak]: bcmxcp-tokamak Maximum number of connections limited to 256 [requested 1024] and then telnetting to port 3493, still from localhost, and I still couldn't connect to port 3493. So, being a nasty suspicious sort, I checked lsof ... nothing's got port 3493 open. checked the process table ... upsd isn't running. It appears to start up, then immediately die. Could this be because something is limiting it to 256 connections? (Not that I'm ever going to need even a tenth of that.... 16 connections would be more than I'm ever going to need to use.) I'm wondering whether I should go tweak the source to request only 256 connections (or even 128) and see if upsd still dies on startup. -- Phil Stracchino, CDK#2 DoD#299792458 ICBM: 43.5607, -71.355 [email protected] [email protected] [email protected] Renaissance Man, Unix ronin, Perl hacker, Free Stater It's not the years, it's the mileage. _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
