Try using another machine and : telnet {server} 9045 and telnet {server} 9046
You should get a response. You can also try lsof -i :9045 To see if tomcat has opened that port. You might not the port opened in IPTABLES The file the firewall outputs its logs to is usually either /var/log/syslog or /var/log/messages. In order to find out which one, you can do grep -q "Packet log" /var/log/syslog && echo yes If it outputs "yes" then it is /var/log/syslog, if it outputs nothing it is most probably /var/log/messages. You can confirm with grep -q "Packet log" /var/log/messages && echo yes On 22/09/10 9:55 PM, "Garg, Saman" <saman_g...@intuit.com> wrote: Hi All, I am having a very strange issue wherein after starting the tomcat instance, it doesn't show any errors and also doesn't listen on port (9046) specified in server.xml as it doesn't list this port on using "netstat" command. But similar thing is working for other tomcat instance which is running on port 9045 on the same machine. I have verified there is no other service running on port 9046 so this port is ok to use. Could anybody please help? Thanks
