Patrick Chevalley replied to the topic 'Atik camera: Cooliing info inquiry failure??' in the forum. yesterday

I also get this error sometime with my Atik314.
In all case this is because of power or USB cable failure. The error is about cooling only because this value is checked frequently by the driver but any other function with the camera fail until you reconnect the camera and restart the driver.
I have no more this issue since I use a good quality and short USB cable to the hub on the telescope itself. Only once because of a power line failure.

The rule just set the environment variable ID_MM_DEVICE_IGNORE=1
Normally this must make ModemManager to not take the device but it is possible your version of ModemManager do not obey to this variable.
Removing with "sudo apt remove modemmanager" is probably a safer solution.

Hi,

0461:0033 is the usbfocus but here it show the manufacturer of the usb chip in the device.
You must not change the file 99-com.rules because it will likely be replaced by a system update.

Create a new file in /etc/udev/rules.d/ . For example named it 80-usbfocuser.rules
In this file I have:
ATTRS{idVendor}=="0461", ATTRS{idProduct}=="0033", ENV{ID_MM_DEVICE_IGNORE}="1", SYMLINK+="usbfocus"

This make ModemManager to ignore this device and it also create a symbolic link /dev/usbfocus to the actual /dev/ttyACM0. The interest is you can always configure /dev/usbfocus in INDI and it work even if you re-plug the device and the ttyACM number change.

The port is /dev/ttyACM0 , the USBfocus never connect as ttyUSB.

Try this command to show the process that can lock the port:
sudo lsof /dev/ttyACM0

Note it can be /dev/ttyACM1 if you unplug and replug.
To be sure, just after you plug, type dmesg and look for the last messages.

This option enable indiwebmanagerapp.service in systemd.
You can check it's status with: systemctl status indiwebmanagerapp.service

Maybe you have another startup script you create in the past for a standalone version of indiwebmanager?
Look in /etc/init.d for something related to indiwebmanager and also using the command systemctl list-unit-files

You cannot use two different mount and keep the same driver name because this name is used for the saved parameters that must be different for each mount.
So change the name in the Device manager, replace "Eqmod Mount" by "Eqmod heq5" and "Eqmod azgti"

I already see this same error with my Atik 314.
In my case this is related to a bad USB cable.
You can look in syslog for a USB disconnect at the time of the first error.

I use VNC a lot, for telescope computer control but also for my build and test server on the cloud. There is no need to use other software than the one provided by the Linux distribution.

If the remote computer has a real screen I want to share, I just run the vino server included with Ubuntu.

On a headless computer I install vncserver, using one of the alternative, both vnc4server and tightvncserver work for me.
A detached session is started by an init script. Something like: /bin/su - $VncUser -c "/usr/bin/vncserver -geometry 1680x1050 -depth 24 :1
In the user home directory create a .vnc directory to contain the password file and the xstartup script the allow you to start the desktop and the application you want.

The client I find the more stable and easy to use is krdc, a KDE application.
If the client is on your local subnet you can just connect with : krdc vnc://host:1

For remote access over Internet the best is to use ssh to encrypt the communication. You probably already have ssh configured for shell access.
For VNC create a tunnel with : ssh -N -p 22 -L 5902:localhost:5901 This email address is being protected from spambots. You need JavaScript enabled to view it.
Then connect using: krdc vnc://localhost:2
