RE: [rhelv5-list] vncserver



All I had to do to switch was edit the .vnc/xstartup file and uncomment
the 2nd and 3rd lines (unset SESSION_MANAGER and exec
/etc/X11/xinit/xinitrc)..restart vncserver and that should be it.

OK, with vnc functional, now I wish to push my luck..... Is there an
elegant
way to teach a 'stock' RedHat system where the GUI is on the console and
use
vnc to either take over that session or to have a session of its own
that
looks just like the console (complete with the Applications, Places, and
Systems drop down menus)? 

With what little I know about startx, it seems it may be an important
part
of this idea, but I find myself without enough knowledge to get it done.

Thanks,

Hey Bill,

	a couple of things:

1) check for the Xvnc process running (that's the server) - it appears
to
be: 

ps -ef | grep Xvnc

2) you can also use lsof to check the open ports:

lsof -P -i tcp:5813 -i tcp:5913

3) Typically, the first time you run vncserver, you will be prompted for
a
password - this is what is needed to connect with the vncviewer. You can
change it with vncpasswd.

4) when you run vncviewer from XP, you need to enter the host and
desktop
(i.e., ":13" in your example), and the provide the password from #3 when
prompted. The port number is important.

In your telnet examples, you are connecting from and to the same box -
can
you telnet from your XP system to the linux system?

Kevin

Subject: [rhelv5-list] vncserver

Preamble: I have never installed vncserver on RedHat before! Didn't
sleep in
a Holiday Inn Express either.

When I use my XP vnc viewer to attempt access, it says 'unable to
connect to
host: Connection refused(10061).

I tried to launch vnc server on 5.0 and now on 5.1. To launch, I simply
typed vncserver at a root # sign. I also tried vncserver :13. I have
configured both 5.0 and 5.1 (two different systems with identical
hardware
installed this week) to turn off the firewall and to not use selinux per
the
installation dialog. On the first instance, the vncserver dialog asked
me
for a password. Apparently it liked it, since subsequent sessions did
not
ask.

I ran nmap -v -sV (ip)   **really cool command!**  and didn't see the
open
ports, but then I tried to telnet into ports 5913 and 5813 and got the
dialog that follows my sig line. This, coupled with the .log file (after
my
telnet commands below) are trying to hint that I did it right.
Unfortunately, since it doesn't work, I did something wrong.

The .log file shows it's unhappiness with my hand telnet sessions, but
does
not increase in size by even one byte when I appempt to connect from a
real
vnc viewer (free 4.1.1) from my XP system. My XP can connect to other XP
systems that are running server.

In searching the web, I see many instances of a firewall being in the
way.
On the 5.1 system, it has no firewall set up and is on my local lan. On
the
5.0, it is about 80 miles away on a wide open T-1 line. I *think* I have
that possibility covered.

Please help me find the intuitively obvious thing that I missed, and how
to
do it!

Thanks in advance!
