Hi all, I am facing problem with implementing 3M RFID system with koha, from log file I am getting below error: *Can't connect to TCP port 6001 on 0.0.0.0 [Address already in use]* Koha version 3.02 OS = OpenSUSE 12.2 SIP 2.0 <service port="8023/tcp" transport="telnet" protocol="SIP/2.00" timeout="60" /> <service port="0.0.0.0:6001/tcp" transport="telnet" protocol="SIP/2.00" timeout="60" /> </listeners> I assigned the 0.0.0.0 IP address and port 6001 to the service, but I want to start it using specific IP address say 178.79.221.342:6001, when I changes the IP from 0.0.0.0 to any specific IP address the SIP service is not getting started. I am using below commands to start SIP: export KOHA_CONF=/path to koha-conf.xml export PERL5LIB=/path to kohaclone perl -I C4/SIP/ -MILS C4/SIP/SIPServer.pm C4/SIP/SIPconfig.xml & but when I checked with ps -ef | grep SIP service is not showing as started. -- *Warm Regards,Vishal Patil*Software Engineer - Nucsoft Ltd. phone: 022 32080161 | mob: 08767505528 www.osslabs.biz www.nucsoft.com vishal.patil@osslabs.biz
