I use OpenNMS and this is how I install it. So far it's worked every time (6 installs). Make sure you open up your IPTables as needed. Let me know how it goes. --Todd

-----Original Message----- From: centos-bounces@centos.org [mailto:centos-bounces@centos.org] On Behalf Of Peter Farrow Sent: Monday, October 17, 2005 5:05 AM To: CentOS mailing list Subject: [CentOS] Tomcat 4 on Centos 4.1

Had anyone managed to install Tomcat 4 on Centos 4.1

I want to run OpenNMS but the dependancy list is tortuous to say the least (Tomcat4, J2SDK etc etc etc )...

I have rpms for tomcat that install ok, but then the services give a ton of errors about missing files when you start/stop them

Failing this can anyone recommend any free Networm Management System for Centos, I only need a simple solution just so that I can import mibs into it and send it traps!

OpenNMS seemed a good choice as it does everything (although rather too heavyweight for what I want), as its taken me and a few Java experts here more than two days to try and install OpenNMS I think its time to move onto something else.

Any advice is most welcome!

Regards

Pete
