Same issue with SSH

Hi, Just stumbled onto this post. I have the same issue with SSH, on a GnuBee PC1. I believe openssh is running (according to OpenMediaVault GUI), but it rejects all connections attempts. Please keep updating this post if you find a solution.

Re: programming Anytone 878

In the instruction you say turn on the radio. How do you do that if it is locked and can be only unlocked by programing?

The radio being factory-locked shouldn't prevent you from turning it on using the right knob. If you're talking about the keypad being locked, then yes that's one of the things that can be unlocked using the CPS.

Works for me

With Neil Browns new kernel (5.2.8 - see, installed (see README) upgrading to Debian Buster worked perfectly for me. SSH access works out of the box without problems.

Your title said RAID1...

I totally agree that a RAID1 would kill the speed of SSD. But then, your post title says RAID1... :-)

Now, I wanted to mention that if you know the name of your device, you can check whether it's a rotational (HDD) or not (SSD). Here is an example of how you get the flag:

alexis~$ cat /sys/block/sda/queue/rotational

The file is either a 0 (SSD) or a 1 (HDD). What you need is the "sda" part of the path. In a shell script, it can be difficult to grab that info. Although a function such as "df ." give you the info, it's not that practical.

Anyway, your solution is pretty much what I had in mind. Thank you.

Finally, USB works!
Thanks for writing this down! I've tried a Virtualbox VM several times for programming radios but could never get USB devices to be visible inside the VM. Turns out, I was missing the vboxusers group. This should open up a lot of possibilities!

Topicons plus
The instruction works, but one important thing is missing. On Ubuntu with Gnome (Both 18.04 and 19.04) you will need the gnome extention TopIcons Plus installed in order to launch VidyoDesktop, otherwise the application will fail to start (at least for me).

Revised configuration necessary for saned under systemd

After encoutering numerous problems in setting up SANED network access with systemd on a Linux Mint 18.3 , here are some important points

1) make sure you do not have saned configured to run under inetd or xinetd as might be the case from an upgraded installation

2) systemd needs a file for socket and an instance service file. To avoid loss of customizations with package upgrades, put these in /etc/systemd/system not overwrite those in /lib/systemd/system

#|  file : /etc/systemd/system/saned.socket

Description=SANED network daemon activation socket




The second item it needs is an instance service file NOT a service file. This means that the file name contains an "@" as in saned@.service and the contents

#|  file : /etc/systemd/system/saned@.service

Description=SANE network daemon instance %i




If you want to do debugging you can add additional Environment lines


For completeness, to mirror the setup in /lib/systemd/system and to emphasize the point when looking in /etc/systemd/system that the file is not missing and that saned@.service is not misnamed, symbolically link /dev/null to /etc/lib/systemd/system/saned.service

 /etc/systemd/system/saned.service -> /dev/null

This is unecessary because of the link present in /lib/systemd/system, but it makes it clear when looking at the /etc/systemd/system directory the configuration being used.

Do a systemctl enable of saned.socket and it will create a symbolic link under the directory

/etc/services should have the entry

 sane-port       6566/tcp   sane saned

Ensure that /proc/sys/net/ipv6/bindv6only is set to 0 (and not set to 1 due to some hack from an old bindipv6only.conf file /etc/sysctl.conf.d) if you are wanting network connections on IPv4 to work.

It may be necessary to ensure that the "net" featured is turned on in /etc/sane.d/dll.d configuration file for your scanner if it is some non-standard configuration.

In your /etc/sane.d/saned.conf ensure your have a "localhost" entry -- should also work but when saned starts up it says checking for localhost, so this is to be consistent. Then add the host names or network IP address ranges permitted to access the service.

Adjust your firewall rules if necessary.

You do not need to add the host IP address to the /etc/sane.d/net.conf file, this will result in you being offered both a local and a network connection to the scanner from the host, so keep it simple for the server host, but do add the server host IP address or name to the net.conf file on the client hosts which need to access the service.

If you then do a systemctl start saned.socket followed by a systemctl status saned.socket you should see

 saned.socket - SANED network daemon activation socket
   Loaded: loaded (/etc/systemd/system/saned.socket; enabled; vendor preset: enabled)
   Active: active (listening) since Wed 2019-05-29 20:12:40 BST; 30min ago
   Listen: [::]:6566 (Stream)
 Accepted: 21; Connected: 0

Now where the "magic" comes in, is that when a connection is made on the socket, systemd fires up an instance of the saned service using the socket name as the instance name (which is why the standard input is set to "null" and NOT "socket" in the saned@.service file).

So if when a remote connection is made you do

systemctl -all -l --no-pager | grep saned you should see

  saned@21-                                    loaded    active   running   SANE network daemon instance 3 (
  system-saned.slice                                                                        loaded    active   active    system-saned.slice
  saned.socket                                                                              loaded    active   listening SANED network daemon activation socket

where the instance number increases by one for each connection.

If you want to advertise the service via Avahi, you could add a service file under /etc/avahi/servvices

<?xml version="1.0" standalone='no'?>
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
