Server used in DOS attack on UDP port 0
Hi,
One of our AWS machines was used in an DOS attack last night and I am
looking for possible attack vectors. AWS tells me it was sending UDP port 0
traffic to a cloudflare address.
This instance had an incorrectly configured AWS security group exposing all
ports.
The server in question is a Centos 7 based FreeIPA server, OpenVPN
concentrator and DNS server.

firewalld services to open for an ADDC
Hai,
If you use that or the AD, then its incomplete, imo.
Your missing ldaps (636) and the GC (ssl) 3268/3269) ports and maybe NTP (123/tcp) if installed.
Maybe you dont need them, just an observation.
Greetz,
Louis

virtualbox
Has anyone gotten virtualbox to run on Centos8? I did the install, and
it complained about missing elflibs, so I installed those, and the
virtualbox install finished without any reported problems.
when i try to run virtualbox, it fails with this message:
Qt FATAL: This application failed to start because no Qt platform plugin

firewalld services to open for an ADDC
I tried the following
firewall-cmd --add-service=dns --permanent
firewall-cmd --add-service=samba --permanent
firewall-cmd --reload
But was not able to connect until I disabled the iptables via
iptables -P INPUT ACCEPT
iptables -F
then I was able to connect my windows 10 pro to my domain.
So my question is what services or ports am I missing to open?

Samba AD firewalld services
Now with firewalld, opening up ports is now 'better' done by opening
services. So what do I need, for starters it seems:
dns, dhcp, dhcpv6, samba, kerberos
Here is the list of services:
RH-Satellite-6 amanda-client bacula bacula-client dhcp dhcpv6
dhcpv6-client dns
ftp high-availability http https imaps ipp ipp-client ipsec kerberos
kpasswd ldap
ldaps libvirt libvirt-tls mdns mountd
