Network installation broken, PHP can't resolve names

Been attempting to use this auto Installer for days. It is broken and does not work.
Debian 12 NGINX.

wget -O - https://get.ispconfig.org | sh -s -- --use-nginx --use-ftp-ports=40110-40210 --unattended-upgrades

I was able to fix one resolver issue by adding a path but now I have another.

Not sure what is going on with this Auto Installer but after several days of messing with it it does not appear to be working. Is there a better way to install ISP config. Not sure why the installer is more problematic than a manual install has ever been.

 

OK, sounds like I need to get the networking in order. Had issues setting up
204.12.225.98/29 network. Locked up the server network several times. What should the interfaces file look like?

I currently have
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug enp2s0
iface enp2s0 inet static
address 204.12.225.98/29
gateway 204.12.225.97
dns-nameservers 8.8.8.8
dns-search nocix.net

up ip addr add 204.12.225.99/29 dev enp2s0
up ip addr add 204.12.225.100/29 dev enp2s0
up ip addr add 204.12.225.101/29 dev enp2s0
up ip addr add 204.12.225.102/29 dev enp2s0

down ip addr del 204.12.225.102/29 dev enp2s0
down ip addr del 204.12.225.101/29 dev enp2s0
down ip addr del 204.12.225.100/29 dev enp2s0
down ip addr del 204.12.225.99/29 dev enp2s0

 

I am just going to reset this and get a fresh load. The only IPV6 configuration appears to be hosts file.

root@mr1:/etc# cat hosts
127.0.1.1 mr1.MyDomain.com mr1
# 204.12.225.98 s254703.nocix.net s254703

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

 

You're one of many lately blaming the installer and/or ispconfig for having problems while the real problem is network issues on the server in question.
It really puzzles me how you guys think you will ever be able to manage and troubleshoot a server when even the most basic knowledge isn't there.

Disable ipv6 globally in your server if you have no ipv6 addresses.

Code:

sudo sysctl --write net.ipv6.conf.all.disable_ipv6=1

(taken from one of the similar posts that could have been found using the search function)

The hosts file is for nothing more than local resolving prior to dns and has nothing to do with ipv6 config of networkinterfaces.
By the way, what happened to the line "127.0.0.1 localhost" in that file?

If you're absolutely sure your ipv4 config is in order than you can try again and the installer will run just fine.

 

Just beware that the command sudo sysctl --write net.ipv6.conf.all.disable_ipv6=1 is used in Linux only to temporarily disable IPv6 on all network interfaces.

For thoroughness, it is often recommended to run additional commands for the default and loopback interfaces as well:

Code:

sudo sysctl --write net.ipv6.conf.default.disable_ipv6=1
sudo sysctl --write net.ipv6.conf.lo.disable_ipv6=1

Verify that IPv6 has been disabled by checking the value in the relevant /proc file via command like cat /proc/sys/net/ipv6/conf/all/disable_ipv6 and if it shows an output of 1, it confirms that it is disabled.

However, it is pertinent to consider that the changes made with sysctl --write (or sysctl -w) are not permanent and will be reset after a system reboot, so to permanently disable IPv6, you need to edit the system configuration files, such as /etc/sysctl.conf or a file in /etc/sysctl.d/, and add the configuration lines there.

To re-enable IPv6 after using this command, run the same commands but set the value to 0. Re-enabling may sometimes require a network service restart or a full reboot to take effect on all interfaces.

The above is a modified answer from Google Search Ai.

 

Same thing and If disabling IPV6 is required perhaps it should be a script option.

NO I am not sure and that is why I keep posting what I have. All I know is what has worked before, It appears that things have changed and Yes confirming hosts and interfaces files is probably the right direction. Additionally I do not see multiple IP examples. AS Far as education goes I am currently in school and it is all windows and CompTIA crap. Not sure how any body with an education makes a network run.

 

Yes and I just retried it. Same error.
