Hi -

I am struggling to get the setup right for OpenVPN to run in both directions.

I have managed to run OMV as OpenVpn server in LAN1. I have an external PC in LAN2 that can connect to OMV in LAN1 fine.

When I now want to establish an Openvpn connection from OMV in LAN1 (via CLI) to a backup server in LAN2, OMV (Debian) complains:

>>TCP/UDP: Socket bind failed on local address [AF_INET][undef]:1194: Address already in use

Does anyone know how to utilise Openvpn in both directions?

My setup is as below:

Code

OMV-LAN1 ----Internet----LAN2 -----PC
                          |--------Backup Server

I will try - thank you.

But the switch for "every N minutes" is OFF.

What is this for then?

Hi - I am having trouble getting the rsync job to work as cron.

My settings for the OMB GUI are below and what happens is that at 23:00 every day, the rsync job runs 60 times (every moniute).

And thats although I have obviously switched the minutes off (see below).

Any ideas? I just want to run 1 backup at 23:00 and not 60.

got it thanks!

MarcS · Jul 30th 2021

ok. So switches keep a MAC table? Or how do they know the destination of a packet?

MarcS · Jul 30th 2021

I see.

So the switch must have an IP table where it knows where packets must be routed to?

Is that how it works?

Hi,

I have a simple networking question involving routers and (un-managed) switches: Does network traffic always go via the router or can hosts, if they are connected via a switch, communicate directly without going through the router?

In the example below all hosts are in the same sub-net:

Can host1 send data to host3 without packets going through the router?

router-----switch-----host1

| |--------host3

|

host2

ok thanks. I managed to get it to work but the email notifications are not going out although email notifications work well from other OMV services.

Any ideas?

I am trying to run an automated rsync job that I can administer in the OMV4 GUI.

The rsync plugin has many good parameters but I cannot find a way to provide the SSH password for an encrypted rsync.

When I use the "password" field in the GUI screen, I get permission denied errors. And the GUI says that this password is only used for the rsync deamon (unencrypted).

How can I provide an SSH password in the rsync OMV screen?

Quote from macom

omv-extras repos moving to github

For OMV4: RE: omv-extras repos moving to github

You should upgrade to OMV5. OMV4 and Debian 9 are EOL

How risky is that upgrade to OMV5? My OMV4 runs pretty stable....

..but the Plugin is now installing -> worked. Thanks!

The issue was the fact that a disabled SMB share was pointing to the external HD.

So it is not enough to disable an SMB share before unmounting the underlying drive, the share must be deleted.

For OMV4:

The commands work up until:

apt-key add omvextras2026.asc which results in error

Code

gpg: no valid OpenPGP data found.

Also, when I press "Check" under Updates I get the following error:

Thanks for the tips.

I have no service linked to that drive.

I also cannot find the restperms Plugin. When I press "Check" under Plugins I get the following error:

Hello all,

I have a problem unmounting an (external) LUKS encrypted harddisk. I would like to remove the disk from my system.

Current configuration: HP N54L running OMV 4.1.36-1

Several internal HDs and 1 external HD connected via USB

The external HD is LUKS encrypted and is currently mounted.

-Filesystem unmount in OMV is greyed out

-LUKS Plugin "Lock disk" is greyed out

- 1 sharedfolder pointing to this HD cannot be deleted (Greyed out)

How can I safely remove this disk?

MarcS · Apr 26th 2021

thanks for the link but this defeats this process seems to automatically unlock all drives after reboot.

That would defeat the whole purpose of drive encryption.

In my solution, there is a manual step, i.e. running of a shell script as root.

MarcS · Apr 25th 2021

So I solved the problem. The issue was some confusion with the mount-points.

I have several LUKS encrypted disks which I decrypt after booting via a script but apparently that now doesn't work anymore after the OMV update. I have to manually decrypt the disks each by hand in the OMV GUI.

After doing that, the Docker path is visible again and docker works.

MarcS · Apr 25th 2021

yes my docker storage path points to a disk that is now (surprisingly) empty. Something must have happened during the OMV upgrade...one disk is completely empty and that was the disk where my Docker path is pointing to.

MarcS · Apr 21st 2021

Seems to be the same problem. I dont even want to re-install docker as I have so many containers up and running which took me weeks to configure. I fear they might all be gone if I re-install Docker.

Is there any one that can help on this Docker issue. Seems to be cause be a recent OMV update.

many thanks

MarcS · Apr 19th 2021

I had Docker running nicely with Portainer and several live containers (Nginx, Nextcloud, Pihole).

After a recent OMV update I cannot get Docker up again. I am posting the output below. Maybe someone can help interpret this.

Journalctl -xe output:
