Re: Port Scan on 371...

Well, port 371 is used by Backweb.  There is a proxy for
many firewalls for the port ( UDP )

Backweb servers 'push' subscribed content to the subscriber
in that manner you are describing.

Obviously, I cannot comment for the IP address you are
receiving the scans from.

Subject: Port Scan on 371...

Hello All,

I'm seeing port scans on our network for port 371:

Which I found port info at:

http://www.con.wesleyan.edu/~triemer/network/docservs.html

clearcase 371/tcp Clearcase
clearcase 371/udp Clearcase

However, I'm not sure what Clearcase is.  Can anyone help with that?

The scan is coming from:  206.251.4.210

Which Visual Traceroute shows as going to the domain:    glbx.net

After configuring my web browser to not trust the site, it is running a web
server, this data comes back from it:

You are accessing a BackWeb channel (it is not a normal Web site).

ARIN lists the network as belonging to Global Crossing.
