[Apcupsd-users] ERROR in pcnet.c at line 650 - Cannot bind socket

[TLV I. T. G. <ITG@TLVENTURES.com>]

Prior to posting I did read the manual, searched the archive, and Googled for an answer.  Unfortunately, I'm still not able to get apcupsd running.  Please forgive me if I've left out any valuable information, I'm VERY new to Linux, this is the only machine I have running it.

Any troubleshooting input you can offer is appreciated.

So here are the details...
I am unable to get apcupsd talking to my UPS.  When I start the daemon the error "ERROR in pcnet.c at line 650 - Cannot bind socket" is logged in /var/log/messages.  My configuration is shown below.

MACHINE INFO
  OS : CentOS (VMware's VMA 4.1)
  VER : Linux 2.6.18-164.9.1.el5
  PLATFORM : x86_64

APCUPSD INFO
  VER : 3.14.8 for RedHat (64bit)

UPS INFO
  MODEL : SMART-UPS 3000
  MGMT CARD : APC9617
  FIRMWARE : aos3.7.3
  CONNECTION : ETHERNET
  PROTOCOL : pcnet

APCUPSD CONFIG
  UPSNAME apc001
  UPSCABLE ether
  UPSTYPE pcnet
  DEVICE 10.1.70.91:apc:<my custom, case sensitive phrase 16 characters in length>
  POLLTIME 30
  NETSERVER on
  NISP 0.0.0.0
  NISPORT 3551

CUSTOMIZATIONS AND NOTES
  - I changed the name of the config file and updated the init.d startup script as per the apcupsd manual in the section describing how to set up multiple instances of apcupsd on the same machine.  After getting the first instance working I intend to use this box to monitor 6 more UPS units.
  - While troubleshooting I made these changes to iptables
     o sudo chkconfig iptables off
     o sudo service iptables save 
     o sudo service iptables stop
  - The host running apcupsd and the UPS management card are on the same subnet and can ping one and other.

Where do I go from here to solve this problem?

Thanks,
Adam
