Hi,

I've got a problem to reach an UPS with apcupsd over ethernet.

Here my Setup:

Smart-UPS 2200 (Firmware Revision: UPS 09.3 (ID18)) with an Network Management Card 2 - AP9630 (Version: v6.2.0)
DNS bvg-usv001
IP 192.168.65.24

debian host with apcupsd
DNS bund-shutdown
IP 192.168.66.26

The apcups_conf:

UPSNAME bvg-usv001
UPSCABLE ether
UPSTYPE pcnet
DEVICE 192.168.65.24:admin:test123

LOCKFILE /var/lock
SCRIPTDIR /etc/apcupsd

NOLOGINDIR /etc
ONBATTERYDELAY 6
BATTERYLEVEL 5

NETSERVER on
NISIP 127.0.0.1

EVENTSFILEMAX 10

UPSCLASS standalone
UPSMODE disable

STATTIME 0
STATFILE /var/log/apcupsd.status

The account and password work with the Website. But I got still a comlost:

When I test the port on bvg-usv001:

nmap -p 3052 bvg-usv001
Starting Nmap 6.47 ( http://nmap.org ) at 2017-06-13 14:23 CEST
Nmap scan report for bvg-usv001 (192.168.65.24)
Host is up (0.0063s latency).
rDNS record for 192.168.65.24: bvg-usv001.bvg.local
PORT STATE SERVICE
3052/tcp closed powerchute
MAC Address: 00:C0:B7:ED:0B:DA (American Power Conversion)
Nmap done: 1 IP address (1 host up) scanned in 0.46 seconds

I guess I've to open the port?

On the USV I tried to set the debian Server as Powerchute Client, but that didn't open the port. I doesn't do anything on the firewall 😉

Bye

Gregor

The PCNET driver relies on a passphrase rather than a password. On my AP9606 it defaults to "admin user phrase". So the driver needs to look like this :

UPSTYPE pcnet
DEVICE 192.168.2.231:apc:admin user phrase

You might want to re-check your authentication just to ensure it is set up right.

If you fire up tcpdump you should see the PCNET packets back and forwards, from memory they are plaintext anyway.
