NethServer Version: NethServer release 7.3.1611 (rc3)

I am using proxmox for virtualization. Proxmox can create virtual machines via kvm or containers.
Actually I use nethserver installed in a vm in kvm via proxmox
But I will like to probe nethserver via container via proxmox.

there are templates in proxmox for several solutions but I can not see a template for nethserver.
In theory increase the performance via containers

are there a time in that you would make e a template for proxmox?

IMHO you’d use a centos template

Thanks Stefano, buy my question is if are there a template for nethserver for proxmox.
the idea is only install the template and not install nethserver after install centos

I think it does not exist… starting from a centos template is, IMO, straightforward…

@Stefano_Zamboni I’m currently trying to install nethserver7 in proxmox 5.1-43 and I’m having trouble with the installation

This is what I’ve done:

Create the CT with this configuration using the template centos-7-default_20171212_amd64.tar.xz:

arch: amd64
cores: 4
hostname: odin
memory: 1024
nameserver: ###.###.###.###
net0: name=eth0,bridge=vmbr0,gw=###.###.###.###,hwaddr=##:##:##:##:##:##,ip=###.###.###.###/24,type=veth
ostype: centos
rootfs: local-zfs:subvol-109-disk-2,size=20G
searchdomain: durero.lan
swap: 1024

Start the CT and enter:

pct start 109
pct enter 109

Configure the CT like this:

# Fix timezone
timedatectl set-timezone America/Havana

# Install the base system
nethserver-install

Before execute nethserver-install I can connect to the CT via ssh and I can ping the CT. After the installation both things stops working, and the file /etc/sysconfig/network-scripts/ifcfg-eth0 no longer exist Also I cannot connect to the server using port 980 on the server ip

One more thing I decided to check open ports with netstat -lanp | grep 980 and I found this:

tcp6       0      0 :::980                  :::*                    LISTEN      269/httpd

So I disable the firewall using

iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -F
iptables -t mangle -F
iptables -F
iptables -X

And only then I was able to use ssh, ping and connect to the web interface on port 980 However netstat -lanp | grep 980 is showing this :

tcp6       0      0 :::980                  :::*                    LISTEN      269/httpd           
tcp6       0      0 192.168.9.9:980         192.168.9.69:45470      TIME_WAIT   -

tcp6 in a ip4 address ? Is this possible?

I try to create a Nethserver 7.9 LCX Proxmox Container and have the same problem with the Firewall/open Ports…

When I use the iptables commands it works just until the next reboot. Is there a way to make the changes permanent?

Sorry for the late response.

After setting the iptables you have to save them to a file

iptables-save > /etc/iptables/rules.v4
ip6tables-save > /etc/iptables/rules.v6

For making them persistent you have to install iptables-persistent

apt-get install iptables-persistent

it loads the files rules.v4 and rules.v6 automatically at startup.

I’ve found this solution at the following site:
