Agent Configuration Assistant fails on installation

Question

Trying to install 9iR2 on Red Hat Linux 7.3. I've got a test server working but the production one refuses to run the Agent Configuration Assistant. It just says
--<snip>--
Parameter "orahome" = /opt/oracle/product/9.2.0
Parameter /nodeinfo" = NO_VALUE
Agent Service Failed
--</snip>--
Is it vital for me to have it running? To what do I need it exactly?
Here's some details on issue, if someone could be able to help me out...
--<snip>--
Command which is being spawned is /opt/oracle/product/9.2.0/JRE/bin/jre -classpath
/opt/oracle/product/9.2.0/JRE/lib/rt.jar:/opt/oracle/product/9.2.0/jlib/srvm.jar:/opt/oracle/product/9.2.0/network/agent/agentca.jar
oracle.agent.AgentCA /orahome /opt/oracle/product/9.2.0 /nodeinfo
NO_VALUE
Configuration tool Agent Configuration Assistant was canceled
Result code for launching of configuration tool is -1
--</snip>--
I read some agent related documentation:
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/em.920/a96676/toc.htm
I checked if the agent was running on the test server and if not, would
it start:

Tried the same on our production server:

Couldn't find any strangeness in the config files either:
/opt/oracle/product/9.2.0/network/admin/snmp_ro.ora
/opt/oracle/product/9.2.0/network/admin/snmp_rw.ora
/opt/oracle/product/9.2.0/network/admin/listener.ora
/opt/oracle/product/9.2.0/network/admin/tnsnames.ora
I'm a bit loss here...

Answer 1

You can to verify if you have a problem with the firewall. Run the next comands
Execute CMD and run
telnet hostname XXXX ------------> where XXXX is the AGENT PORT . This port its configure in the emd.properties file. This file is in the AGENT_DIRECTORY\sysman\config\
If you dont execute a telnet to this port, you have a firewall problem
