Technical Help / How to completely reinstall Postfix and Roundcube?

« on: August 06, 2022, 08:27:49 pm »

Ever since I tried to set up a relay server, Roundcube reports: Cannot connect to the IMAP server
I can't connect to Thunderbird either.
I suspect that the IMAP configuration is completely destroyed.
>>> New install of EHCP solved this problem.

I worked according to this guide:
https://www.linuxhowto.net/how-to-set-up-postfix-smtp-relay-on-ubuntu-with-sendinblue/

Unfortunately, the authentication of the domain doesn't seem to work either.
After more than 12 hours still no verification.
How/where do I have to enter this information (see screenshot)?

Technical Help / Re: 503 service unavailable after LXC upgrad to Debian 11

« on: July 22, 2022, 08:12:53 pm »

Solution (note in german):

Backup ehcp (alles auswählen!!!!!)
crontabs backupen
home Verzeichnis backupen
(ev auch Mail Konfigurationen (postfix/main.cf usw)....)
Printscreen der netzwerk einstellungen des CT machen (in Proxmox Host)
CT backuppen
CT löschen
Neue CT mit Debian 11 Template erstellen (mit gleicher Nummer wie vorher)
MAC wieder anpassen (in Netzwerk Einstellungen > siehe den Printscreen)
/etc/ssh/sshd_config > permit_root_login = yes
SSH Port hier auch anpassen
apt update
apt upgrade
root PW anpassen wie früher (mit: passwd root)
reboot oder service ssh restart durchführen.
ehcp installieren
ehcp Backup restoren (das dauert!....keine Info dazu sehbar)

Das Forum sollte jetzt wieder funktionieren.

This is for a LXC container (Proxmox)

Google translator:

Backup ehcp (select all!!!!!)
backup crontabs
backup home directory
(possibly also mail configurations (postfix/main.cf etc.)....)
Make a print screen of the network settings of the CT (in Proxmox Host)
Backup CT
Delete CT
Create new CT with Debian 11 template (same number as before)
Adjust MAC again (in network settings > see the print screen)
/etc/ssh/sshd_config > permit_root_login = yes
Adjust the SSH port here as well
apt update
apt upgrade
Customize root PW like before (with: passwd root)
reboot or service ssh restart.
install ehcp
Restore ehcp backup (this takes time!....no information visible)

**Technical Help / solved 503 service unavailable after LXC upgrad to Debian 11**

« on: July 08, 2022, 09:34:02 am »

Hi
After upgrading the (Proxmox) LXC from Debian 10 to Debian 11, I only get "503 service unavailable" on EHCP and Xenforo.
I have no idea where the problem could be.
Has anyone a idea or had this problem themselves?
To keep up productivity, I restored the Debian 10 container again.
So the Debian 11 container is currently not running anymore.
