Install NetXMS Web Frontend:
wget http://www.netxms.org/download/webui/nxmc-2.0-M4.war
cp nxmc-2.0-M4.war nxmc.war
cp nxmc.war /usr/local/tomcat7/webapps
service tomcat start

I followed everything but can't get web interface 127.0.0.0:8080/nxmc/ to open at all.
I have no idea were to troubleshoot other than to check firewall does pass traffic. I looked at firewall and opened port 8080 but still no luck.
Please looking for any help.
Thanks Centos user
