Re: mod jk2/tomcat communication problem
kaleb, can you telnet to the tomcat connector port? 8009 is the default.

Re: mod jk2/tomcat communication problem
Alex, thanks for the response. I didn't try telnetting to port 8009, but will next time it goes down (I wish I could say *if* it goes down again :( ). I did nmap the box at that time, and it showed that the port was open. I'm going to try to switch to Unix sockets soon as well, as I hope that might fix the problem, but I'm not sure if that disallows me from using the load balancing (which I haven't setup yet as I don't have a backup machine) in the future or if I just have to reconfigure it so that the other channel uses the socket based connection? Thanks for the help. --Kaleb On Wednesday 22 September 2004 8:04 am, Alex wrote: kaleb, can you telnet to the tomcat connector port? 8009 is the default.
