Hi Fujita: Actually, that's the strange part, I checked (and double checked) and there's no services running listening or already binded to port 8080.
Both "lsof" and "netstat" commands did not return anything for port 8080 tester@ubuntu1:~/ryu$ sudo lsof -i :8080 tester@ubuntu1:~/ryu$ sudo netstat -anpt | grep -i 8080 As a test, is it possible to change ryu-manager's default port from 8080 to something else? I took a quick look at the code, 8080 seems to be coded in multiple files. I have pretty much ruled over python environment now as I am using pyenv and are using the same local python installations to my /home/ directory as my Redhat machine (where the issue does not occur) Much Thanks Morgan Yang -----Original Message----- From: FUJITA Tomonori [mailto:fujita.tomon...@lab.ntt.co.jp] Sent: Wednesday, January 08, 2014 6:31 PM To: Morgan Yang Cc: ryu-devel@lists.sourceforge.net Subject: Re: [Ryu-devel] ryu-manager error on ubuntu 12.04 On Thu, 9 Jan 2014 00:51:55 +0000 Morgan Yang <morgan.y...@radisys.com> wrote: > Hi All: > > I'm seeing a strange issue on one of my Ubuntu systems.
