speaking about Linux firewalls

[David Demland]

Craig,

I do not think it is CA software because I have not seen it on my network
and I use CA software. When I do a lookup on the IP 213.254.229.147 I get
the following information:

OrgName:    RIPE Network Coordination Centre
OrgID:      RIPE
Address:    P.O. Box 10096
City:       Amsterdam
StateProv:
PostalCode: 1001EB
Country:    NL

This also supports my idea that it is not CA since the IP is in Amsterdam.
When I try to connect a HTTPS connection to the same IP I got a message with
a SSL certificate from a248.e.akamai.net. The look up for akamai.net show:

 Akamai Technologies, Inc.
 8 Cambridge Center
 Cambridge, MA 02142
 US

When I connected a to akamai.net I get a coming soon page. So I tried to
connect to akamai.net through a HTTPS connection. This time I get s
certificate from plesk of SWsoft, Inc. in Virginia.

I am not sure what all this means, but it just feels funny to me. Maybe some
else could shed some more light.

A network where I have one.

Just set up a new Win2K3 server (don't lecture, I have as much religion
as the next guy). It's been up for 3 weeks or so and before we went
live, it punked out (seems to be a memory problem - ahem - Dell)...

Anyway, I happened to run netstat on the sucker and what do I see but a
connection that makes no sense at all since it is not exposed to the
internet in any fashion.

TCP MY_HOSTNAME:3289 213.254.229.147:http  ESTABLISHED

I can ping that ip address and it's really bothering me. I am going to
block it at the firewall but I can't get a handle on it.

fingerprinting...

# nmap -O 213.254.229.147

Starting nmap 3.50 ( http://www.insecure.org/nmap/ ) at 2005-09-22 19:53

Interesting ports on 213.254.229.147:

Nmap run completed -- 1 IP address (1 host up) scanned in 16.391 seconds

Anybody have any ideas what is going on?

Obviously I put new rules into Linux firewall and rebooted both systems
but blocking that one ip address isn't likely to stop whatever it was
that was connected - it may be something like Computer Associates
BrightStor/ArcServe doing a phone home thing but it really bothered me.
