Humm, Could windows machine be blocking the port going out? If your using putty as a ssh client you could try to port forward (5901, 5901) through the ssh session and then try to connect using localhost:5901 or localhost:5902 on the windows machine and see if you can connect. It can be done with other ssh clients but I've only used putty, so I know it can be done with it. You might also compare some of the settings to this page http://wiki.centos.org/HowTos/VNC-Server You could try stopping the servers and running the vncserver in the console to see if there are connections or errors - but I'm not sure with the configuration your using if that is possible. I'm not sure what else to offer. -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of Larry Martell Sent: Friday, October 11, 2013 7:13 PM To: CentOS mailing list Subject: Re: [CentOS] VNC On Fri, Oct 11, 2013 at 4:45 PM, Terre Porter <tporter at webpage-builders.com>wrote: > You can specify the port with the IP by using the colon with the ip. > > x.x.x.x:5901 or x.x.x.x:5902 > Those both give me connection refused (as opposed to without the port, where I get connection timed out) > > > -----Original Message----- > From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On > Behalf Of Larry Martell > Sent: Friday, October 11, 2013 6:35 PM > To: CentOS mailing list > Subject: Re: [CentOS] VNC > > On Fri, Oct 11, 2013 at 4:26 PM, Terre Porter > <tporter at webpage-builders.com>wrote: > > > The instructions out linked to has a type-o at the end says to > > connect to > > ip:5801 should be 5901. > > > > If your using a vnc client uvnc, tightvnc.. try using just the ip > > without the :port part or :1 for the 5901. > > > > I am unfortunately connecting from a windows box that I do not have > admin rights on.
