Yes. In fact, you should *never* run x11vnc as root.

The Official Paravel Way[tm] way to do this is to use the ‘x11vnc-auto’ package:

1) Get a root shell.

2) Enter the following commands:

yum install x11vnc-auto
systemctl start x11vnc-auto.socket
systemctl enable x11vnc-auto.socket

3) Close the root shell, then get a non-privileged shell (user ‘rd’).

4) Enter the following command:

vncpasswd

Which will prompt you to set a VNC password.

5) You’re done.

Viewer connections to port 5900 will now spawn their very own private x11vnc 
instances sharing display :0, running as user ‘rd’. If that instance 
crashes/locks up/whatever, it will affect only that particular connection; 
others will be unaffected, as will the ability to start new connections.

Cheers!

Hi Rob

I find that NoMachine is more reliable and performs much better on lower 
bandwidths and If this go wrong you can ssh into the server and restart 
it using the cli. You don't need to install the full version on the 
clients server/client just the client enterprise version (free) will do 
the trick.


You can also try the NX open source version if you wish.

Thanks

Re: [RDD] x11vnc woes

[Geoff Barkman]

I'm wondering if having another remote desktop client installed might help
get over your problems?
There is the commercial software TeamViewer and another that I use called
dwservice.net You don't have to worry about any port forwarding through
your firewall etc. DW Service is opensour ce and free.
Even if you just remote in for a short time enough to restart the x11
service etc.
Many thanks

Hey Rob,
I've had MANY issues with x11vnc running consistently on Debian 8 Jessie
with RD 2.10.3. It's configured to run in systemd. Sometimes when I try to
remote in, the greeter window is completely missing. When that happens, I'm
able to SSH in and invoke -- sudo service vncserver@:0 restart -- to restart
x11vnc and then I'm able to login like usual. If x11vnc freezes, the only
way I've been able to recover is to SSH in and reboot the machine, which
really sucks. 


That's exactly what I experienced this morning. You should never have to 
reboot a GNU/Linux box.


Here's a thought: can x11vnc be run in user mode, i.e. not as root?

Re: [RDD] x11vnc woes

[Rob Landry]

I do have a script running to restart x11vnc. If it crashed, the script 
works perfectly. But this morning instead of crashing, it froze. And the 
more I think about it, the more I think there must be some underlying 
issue. I've got a lot of CentOS 7 machines running Rivendell, as well as 
some older RD machines built on Debian. Have any of the Debian ones ever 
frozen? I'm not sure.


But the thing is, this machine gets a lot more VNC connections than any of 
the other machines. And people stay connected a lot longer and do a lot 
more. On the others, someone might reload a log or insert a spot, then 
disconnect. These people stay connected for hours, doing exactly what they 
would if they were live in the studio. I've never had a client do that 
before.


I have one other client doing live remote shows, but their people don't 
have remote access to Rivendell; they run everything, music and all, from 
their homes.

Looks like a reasonably set of command line options. How is it being
started?

My next step in troubleshooting might be to run x11vnc under strace(1),
like this:

 strace -f -ff -tt -s 1024 -o /tmp/x11vnc /usr/local/bin/x11vnc
-display :0 -auth guess -rfbauth /root/.vnc/passwd -o
/var/log/x11vnc.log -shared -forever -bg -rfbport 5900

(watch the text wrap)

The problem with this is the ever-growing files in /tmp. strace writes
its output to those files until x11vnc crashes again. This makes it
problematic if you cannot reliably *make* x11vnc crash. You could
throttle the tmpfile growth by limiting the system calls strace records,
but this might also remove valuable troubleshooting information...

At this point I'm not sure what to tell you, other than see if you can
reliably recreate the conditions under which x11vnc crashes. If you can
do that, it will be much easier to run x11vnc under strace and see
exactly where it crashes.

I have not encountered the crashing x11vnc problem you describe. It has
been completely dependable for me. Can you provide the details about how
you invoke x11vnc (systemd service, user launched, etc.) including the
command line and all the arguments?

One of the stations I work with introduced me to DWService
(https://dwservice.net/) about a year and a half ago. I have mostly
successfully[1] been using and recommending it for remote Rivendell
access ever since.

DWService is a free[2] service that uses "the cloud" as an
"intermediary", or "meeting point", so it may not be desirable for some
users. It operates by running an agent on the computer one wants to
control, and a web browser on the client computer. In addition to remote
desktop access, DWService offers simple remote file access, remote text
file editing, and remote command line access. It includes the ability to
configure fine-grained access control to each of these access methods.

The service requires you to create an account at dwservice.net, but once
you have a "share" set up, users who simply want to connect to the
remote computer do not need dwservice.net accounts, they simply need the
URL to the remote computer.

Lots more information on the DWService website. I have no affiliation
with the organization other than as a satisfied paying customer.

Hope this helps!

[1]: the agent can "self update"; one update a few months ago caused
access problems on CentOS. I worked with the developers to fix it. So, a
problem was introduced, but the developers were very responsive and they
resolved problem.

[2]: the service is free to use, and one can pay the developers.
Contributing money gets you higher bandwidth and thus better performance.

Re: [RDD] x11vnc woes

[Rob Landry]

Here is the x11vnc command:

/usr/local/bin/x11vnc -display :0 -auth guess -rfbauth /root/.vnc/passwd 
-o /var/log/x11vnc.log -shared -forever -bg -rfbport 5900


It's run by a startup script triggered by root's crontab at boot time.

There are no entries in any logs that show any problem.

[RDD] x11vnc woes

[Rob Landry]

I have a client who is running RD 2.19.3 running on CentOS 7, installed 
according to the Paravel instructions. Most of his people are doing their 
shows from home via Comrex Access. They are VNC'ing in to the Rivendell 
system in the air studio to control rdairplay and doing their breaks live 
via the Comrex link.


Most of the time it works flawlessly, but once in a while the x11vnc 
server will either crash or freeze. When it happens, the current song will 
run out and they'll be silent for several minutes while they go looking 
for someone to VNC in and fix the problem.


This morning, x11vnc froze; I had to use kill -9 to kill it, and when I 
restarted it, the new process immediately froze. Only rebooting the system 
got it working -- not something I like doing when I'm an hour and a half 
away and there's no one at the station.


I have tried downloading the latest x11vnc code and compiling it manually; 
that hasn't helped. The logs don't offer any clues.


I know this isn't strictly a Rivendell problem, but I'm wondering if any 
of y'all have encountered it. Is there a better option than x11vnc? I 
suppose I could try vino.


Thanks,


Rob
