Hello @stephdl, where in the Nethserver GUI can I adjust firewall settings to open port(s) for Nextcloud Talk? Or even temporarily turn off firewall to see if my Nextcloud works?
Thank you!

Proxmox HA chat
Hi
I fully agree with you, i personally think this NethServer forum one of the best in all open source. The people here make it so… @support_team & @dev_team, you’re meant too!
That’s also the reason I try to help as best as I can here…
Proxmox is great software, the best virtualizer in my opinion. But as it works so well, their forum is a bit “lacking”, and doesn’t come close to NethServer’s forum here!
I do run about 20-30 Proxmox / Nethserver Combos for my clients, mostly SME companies.
All use NethServer as AD, Mail, File, Print, NextCloud and Zabbix monitoring.
At all clients, i use shared storage on NAS (Mostly Synology) using NFS on Proxmox.
On Proxmox, i use XFS due to far better performance than Ext4…
I’d like to use CEPH, which is very reliable and solid. If it’s enough for CERN in Switzerland with their LHC (Large Haydron Collider) and the amounts of data they produce… Also, seeing who is behind CEPH… And CEPH is distributed…
But reading their HW suggestions… Start with 10 GBe networking…
I just do not have that kind of hardware spare, lying around to test and gain experience with CEPH yet, but i will get there…
With your Hardware, I’d setup 2 Proxmox and a NAS. I do approve of FreeNAS, ZFS is great, when not one of the best filesystems at all!
Have your NAS Backup to a USB Disk. Seagate Backup Hub + is a great buy, for a 8 or 10 GB USB3 Disk. I use those a lot. I’d also suggest using 1 or 2 1 GBe Links for the cluster network. Note, these must NOT be bonded, use the proxmox suggested built in redundancy protocoll for this, if using more than 1 link. I think 1 link is sufficient in your case.
See these networks…
Some of my clients are also multi site.
All have local daily backups, (both Server backups, eg Nethserver) and Proxmox live backups. But also Off-Site Backups, usually to the same modell NAS at home of the companies boss…
Higher availability in case the office NAS fails, we take the home one to the office until replacements come… (See image 2, below. The othe two have this too, but they are shown on other maps - the network is more complicated and larger.).
My 2 cents

Collaborative tools for schools
That’s basically right.
What if we want to use the LDAP/AD userbase or mailserver which does not support it?
Why do we need it?
Honestly I am not a big fan of multi-tenancy, it’s more a reseller thing than it does improve technology IMO.

Hi Markus
Our user oneitonitram (Martin spelt backwards, see the end…) happens to be in the provider business and want’s to provide european class service to african schools.
Tough work, but I support the idea - and even helped him set up Zabbix monitoring. Not that easy, even I’ve never dealt with a distributed hosting network for a provider…

PS: you were meant too, with my comment at Proxmox HA chat!

The Trouble In Calendars
Hi Stephane
You might not be aware of this, but our user oneitonitram (Martin spelt backwards, see the last bit!) happens to be in the provider business, and he’s trying to bring european standards in education to the less fortunate in africa!
It’s a tough job, but I approve of it morally - and actually helped him a few weekends ago to set up his Monitoring with Zabbix. That was tough, I’ve done a lot, but even I have never setup monitoring for a distributed, hosted Provider environment.!!!
He does post a lot, has his shares of issues, but I support the case…
My 2 cents

What about dolibarr

Collaborative tools for schools
I support helping schools too and I really appreciate the work of @oneitonitram
I am afraid of the technical solution because
- Nethserver just doesn’t support multi-tenancy. We’d need a base to collect all data.
- Nethserver is more a gateway/server than a datacenter as regards scalability, see Installation of Captive portal
And besides the technical things:

Zabbix and mrmarkuz repo testing
Here is a simple gimmick, easily addable to zabbix on NethServer:
A swiss railway clock, much better readable than the provided one.
This is based on:
http://www.3quarks.com/de/SVGUhr/index.html
Basically I stuffed the prepared SVG file into Nethservers html folder, and refer to that in the url. As Zabbix and NethServer are on the same server, this isn’t an issue, it would not even be if run of a different web-server…
A gimmick, but thought you might like it: The ÖBB clock or DB version can also be set, if you prefer a “Wiener” ambiente…
Andy
PS
I also use this im my Home Assistant setup (HASSio)…

What about dolibarr
Could you explain line by line what you did, for the migration and what it failed. Indeed the ldap is build with a mysql importation, maybe after the migration you need to trigger the event nethserver-dolibarr-update to import the new login/password inside the database.

Nice, I am going to implement it in next module release.

Proxmox HA chat
@Andy_Wismer Thank you for the detail, unfortunately where the servers are I can’t add any external storage like that, so I plan on backing up offsite from the freenas.
I will formulate my plan and post it here, let me know what you think.

What about dolibarr
- I installed dolibarr on a Testserver and did the initial setup with my company-data, customers…
- I did a backup on the Testserver
- I installed dolibarr on a Productionserver
- I restored the mysqldump from the Testserver on the Productionserver
- I tried to login with AD credentials, AD is installed on both servers but with different passwords…

Cannot access cockpit Web UI (port 9090)
New NethServer was perfectly accessible over VPN. There was no problem on that. At some point it just become not accessible (for more than one fresh installation) even then I could still access it over SSH.
When I check, 9090 port was not listened. Moreover, there were some “dead” status for cockpit service as I shared above.
I do not think it is old server was not allowed to access situation here. I have no idea what was the problem either.

Just added a third node–took down my xcp-ng server to put Proxmox on it instead. Six sockets of X5650s and 192GB of RAM among three nodes–should be enough for a while…

try to trigger the event nethserver-dolibarr-update, verify that the file /usr/share/dolibarr/htdocs/conf/conf.php gets the good settings, compare with account-provider-test dump

OK, but no time left. I will try it tomorrow…
