Hi I am using SuSE 8.2 and the included apcupsd package 3.8.6 with an APC SmartUPS 1000 and a Smart signalling cable (copy of an original one). Starting apcupsd works ok. Running "apcupsd status" results in the desired parameter listing so I know that 'something' is working. Removing the serial cable generates an error message and inserting it again results in a message announcing renewed contact with the UPS. I have tried both COM1 and COM2 and changed the variable in apcupsd.conf to ttyS0 and ttyS1 respectively, combined with the above action. Thus, I know that this variable is set correctly. Running "apctest" results in this (not exact transcript of an) error message: apctest FATAL ERROR in apcserial.c at line 100 Unable to create lock file apctest FATAL ERROR in apcserial.c at line 100 Unable to create lock file Aborting apctest Or something like that. Does anybody have a clue? Thanks in advance. /Niclas _________________________________________________________________ Tired of spam?
