It appears that it is affecting multiple distributions including Debian

Your IP address is flagged as spam in Real Time Block Lists. Are you
using a dynamic IP address? You may have a mis-configured server that is
allowing spammers to relay through your server. Another possibility is

The normal usage for a /48 block is to divide it into /64 sub-networks
and use DHCP to issue addresses to each subnet from the corresponding
/64 segment.

Linux server attacks are nothing new. 14 years ago I was installing a
server, Red Hat 7 I think, and in the hour or so after I installed it to
the time I applied the patches it was infected with an Apache ssl trojan.
Years ago I moved sshd off port 22, disabled password logins and use
certificates
Chances are there is firewall software on the laptop blocking it.

I question why you want accounts without passwords when logging in via
SSH and public keys does not use a password or even ask for one. Also
anyone logged in can change users with only an su - and not
need a password.

Aha! non-CentOS drivers? Are these from the OEM? Theyprobably need to be
rebuilt to the new kernel.
Have you tried booting into "safe" mode or with video drivers disabled?
Just how you do that with CentOS I don't know but there should be
instructions somewhere on the WEB.

One thing I also do is to listen on an alternate socket way up high,
like 5, to bypass ISP's that restrict port 25 and 465 to their own
