It is was coming from some of the same IP's that broke into my systems a
few years ago. I do not know if it is the same ones or not, because they
trashed 3 systems. They over wrote 650-750 GB with "DIE SCO DIE SCO DIE
SCO..."

I do have proxies for some things. My OS is openSUSE 10.3 for
virtualization. I also have a private Build Service. I am just upgrading
it to 0.9.1 released today.

It is from what I have seen. I just finished moving my 900 GB ftp archive
to my OpenSUSE 10.3 box. My setup is as follows. 6 systems with various
Linux Distro's one each for development. 8 virtual Systems (OpenSUSE
factory, OpenServer 5.0.7, OpenServer 6, UnixWare 7.1.3, UnixWare 7.1.4,
FreeDBD, NetBSD, Test Linux Distro). 3 machines one for each SCO OS.
SlackWare, Fedora, CentOS, one of each of the Ubuntu, and 4 other linux
distro's. So yes I am already running things virtual-lized. I have my
own OpenSUSE BS. The are looing at changing the name. I do maintain a
few Open Source Software packages for Linux. I am a very active member of
the OpenSUSE community. So yes, I do know a bit about linux. I have been
using it since Linus first released it.

It is much more. They are using all bandwidth. It is crafted in such a
way allow just enough to flood and keep my bandwith tied up. Saddly, I
have had to suspend service to somethings at the momment. I have a lot of
it automated. Moving most things to where I have iptables has allowed
this, but the few people that use my machines for various Open Source
Software are getting really upset. My bandwidth is really being taken.
I have been forced to only allow 3 connections attempts per IP address per
minute for ftp. SSH access to my machines is only via ssh keys. I do not
allow any password logins. On the OS's that have IP tables, I use the
following where ethX is the externel interface.

iptables -A INPUT -p tcp --syn --dport 22 -i ethX -m recent --name
sshattack --set
iptables -A INPUT -m recent --name sshattack --rcheck --seconds 60
--hitcount 3 -j LOG --log-prefix 'SSH attack: '
iptables -A INPUT -m recent --name sshattack --rcheck --seconds 60
--hitcount 3 -j DROP

The above seems to get the script kiddies. It is interesting how they are
adapting their attack on my systems, based on my defenses and changing of
them.

If you look at my DNS records you can get an idea of what OS's are on what
IP address. Some machines are not available to the internet although I do
own the entire class C 198.60.105.0. I did have 2 other class C networks
but I allowed Xmission to take over them. I had at one time 3 class C
networks with OS's on each IP available to be used over the internet for
free. I now limit who has access for free.

I have 250 HD's with various OS's and versions that I switch in to support
the many UNIX and Linux OS's. I have online for use by request and
meeting certain standards.

So for final listing of what I have available. is as follows

2 BSDs (Virtualized)
6 Linux Distro's latest a machine each.
6 SCO machines with 2 each of OpenServer 6, OpenServer 5.0.7, UnixWare
7.1.4 (3 are virtualized)
4 other UNIXs

Virtualized OS's based on my customer needs. Saddly 3 MS machines with
no direct internet access from the outside all Natted. I keep 8-20
machine running daily for various development needs. Some machines
varry based on what people/customer needs/request for usuage.

You may say I am a big proponent of Open Source Software and it's usage.
I do have some of the users of the various OS's monitoring things. That
is why our current Black list is 8000 IP addresses, with dynamic IP's
being added/removed per Iptables where possible. I wish I had IP tables
for OpenServer 5.0.7 and OpenServer 6. I have not been able to get LKP to
work on OpenServer 6. I just do not have all the peices. I do host lxrun
ftp download. I just have not been able to get it to work with ipf to try
and simulate iptables. I really wish SCO would release LKP for OpenServer
6. Then this really would not be as big as an issue.

I just had to let off steam from the last 3 days of round the clock moving
tunning things.

Thanks,
