Obtain a list of all Administrators
If want to get a list of all administrators, run the next command:
su - zimbra zmprov gaaa
To reset the administrative password:
su - zimbra zmprov sp <admin email address> <new password>
Check the new password in the Admin Console
To access the admin console:
https://YOURHOST:7071
Remember that the administrative console (sometimes) requires a full email address as the login name, so you may be using the correct password and the wrong login!

It’s assumed that you already have a vpn server deployed in your network, created user, password and enabled bridged network during vpn server configuration. A sample snippet of VPN Server Bridge enabled is below-
So here’re the setup value-
Let’s start.
My setup was done on Debian-10 fresh installation, should work on any linux distro though, it’s simple. The dependency packages that I needed were development tools/build-essentials and few other which were installed as below-
apt-get update apt-get install build-essential gcc openssl apt-transport-https

Step 1 – Install Packages Dependencies
In this first step, we will install some packages dependencies needed by the Document Server, including the RabbitMQ-server, Redis, and Nginx-extras.
Update your Debian system repository and install Document Server packages dependencies using the apt command below.
sudo apt update sudo apt install redis-server rabbitmq-server nginx-extras gnupg2
Once all installation is complete, check the following services using the systemctl command as below.
systemctl is-enabled nginx systemctl is-enabled rabbitmq-server systemctl is-enabled redis-server
Now make sure all of these services are enabled and will automatically run on the system boot. Continue reading “Install ONLYOFFICE Document Server with Nginx on Debian 10” »
I was having this strange issue, where a running busy VM stopeed all of a sudden due to high CPU or Memory overload issue. So manually had to start everythime. In order to avoid this, created a small script to start the VM in case if it’s down.
#!/bin/bash # Set environment PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin su - if [[ $(qm status 101) = *"status: stopped"* ]]; then echo `qm start 101` fi
To clone your VM and spawn new instances in KVML
# virt-clone --original {Domain-Vm-Name-Here} --auto-clone
OR
# virt-clone --original {Domain-Vm-Name-Here} --name {New-Domain-Vm-Name-Here} --auto-clone
OR
# virt-clone --original {Domain-Vm-Name-Here} \
--name {New-Domain-Vm-Name-Here} --file {/var/lib/libvirt/images/File.Name.here}

Step 1 – Install and Enable Remi Repository
Firstly, we will add the Remi repository to the CentOS 7 system. The Remi repository provides the latest version of Redis package for our installation.
Before adding the Remi repository, let’s install the EPEL repository and yum utility packages.
sudo yum install epel-release yum-utils
Now add the Remi repository for CentOS 7 using the yum command below.
sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
After that, enable the ‘remi’ repository using the yum-config-manager tool as below.
sudo yum-config-manager --enable remi
The Remi repository has been added and enabled on the CentOS 7 system, check using the yum command Continue reading “Install and Secure Redis on CentOS 7” »
Step 1: Installing Docker
The Docker installation package available in the official Debian repository may not be the latest version. To ensure we get the latest version, we’ll install Docker from the official Docker repository. To do that, we’ll add a new package source, add the GPG key from Docker to ensure the downloads are valid, and then install the package.
First, update your existing list of packages:
sudo apt update
Next, install a few prerequisite packages which let apt use packages over HTTPS:
sudo apt install apt-transport-https ca-certificates curl gnupg2 software-properties-common
Then add the GPG key for the official Docker repository to your system: Continue reading “Install Lancache on Debian 10” »
