Hi,
looked nice,but maybe to nice :-(
after my 'solution' I was able to update tjener but couldn't login to
gosa anymore.
So my problem is still the same:
Tjener is installed and is able to reach addresses in the internet
after installation and BEFORE reboot.
After reboot gosa is available but tjener has no idea to resolve e.g.
debian.org
In the meantime I reinstalled with disabling the onboard copper nic,
disabling dhcp of the fritz!box and entering '10.0.0.1' as default gw
and '10.0.0.1 185.150.99.255' nameservers.
Installation still renames enp1s0 to eth0.
Before reboot I had the following:
root@tjener:~# cat /etc/network/interfaces
# Created by debian-edu-profile during the Debian installation.
#
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

obviosly the right nameservers are missing?

Hi again,
writing leads to thinking!
In my post I missed the entries of the lo device:
root@tjener:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback
dns-search intern
dns-nameservers 127.0.0.1
and of
root@tjener:~# cat /etc/resolv.conf:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by
resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "resolvectl status" to see details about the actual nameservers.
nameserver 127.0.0.1
search intern
Editing /etc/network/interfaces to
auto lo
iface lo inet loopback
dns-search intern
dns-nameservers 10.0.0.1
# dns-nameservers 127.0.0.1
did the trick!
root@tjener:~# cat /etc/resolv.conf

Hope that's the right solution.

Hi Folks,
I've got a problem with a freshly installed tjener:
Fujitsu PRIMERGY TX100 S1, 8GB RAM
onboard Intel NIC (enp0s25 during installation)
PCIe Intel Fibre NIC (enp1s0)
The later should serve the 10.0.0.0/8 net, the copper one is in reserve.
Installation over fibre, getting 10.0.2.2 via dhcp from my configured
Fritz Box ran fine. Chose Main Server and Workstation, but no ltsp
(don't need it here) and partitioned manually.
after installation, /etc/network/interfaces was configured this way:
auto lo
iface lo inet loopback
dns-search intern
dns-nameservers 127.0.0.1
auto eth0
iface eth0 inet static
address 10.0.2.2
netmask 255.0.0.0
broadcast 10.255.255.255
gateway 10.0.0.1
# The commented lines below is to be used if a DHCP server is in use
#iface eth1 inet dhcp
iface eth1 inet dhcp
But: eth0 is the disconnected copper onboard nic and eth1 the fibre card!
So i edited /etc/network/interfaces
auto eth1
iface eth1 inet static
address 10.0.2.2
netmask 255.0.0.0
broadcast 10.255.255.255
gateway 10.0.0.1
iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
broadcast 192.168.1.255
and restarted.
Now I can reach tjener from the 10.0.0.0/8 net, but tjener doesn't
reach the world outside of this network:
root@tjener:~# ping debian.org
ping: debian.org: Der Name oder der Dienst ist nicht bekannt
Some diagnostic, that didn't help me solve the prob:

Any suggestions what's going wrong?
