Hey CentOS folks!
I have an interesting issue with starting a server on a CentOS 6 KVM guest. The server (service) in particular is gotour, which is a web application created by Google and their Golang developers, intended to teach users the basics of using the Go programming langauge.
When starting gotour, the program claims to be binding to port 12049, but the VM doesn't seem to be serving anything on that port. Upon checking the netstat output, I see a process bound to port 12049.
It is definitley possible that the problem is with Go itself, but I'd like to rule out the possibility that something on an out-of-the-box CentOS 6 image might be preventing the server from working.
Here is some of the output:
[appengine@centos6-paas-dev gotour]$ gotour 2014/04/17 22:04:33 Serving content from /home/appengine/goprojects/firstproj/go/src/code.google.com/p/go-tour 2014/04/17 22:04:33 WARNING! WARNING!

Any ideas?
