Run nmap with the -sV option. It will then try to detect the real
application listening on port 8081 (blackice-icecap is just listed as
the "default" applicatiohn in the nmap services file).
I assume it might be McAfee ePolicy Orchestrator (the agent normally
runs on this port). You can varify this by connecting to
http://192.168.126.245:80801

Subject: Port 8081 mystery
HI list...
I ran a nmap scan on quite a few machines on my internal subnet and one
port that appears on all those scans, especially the machines that are
still running adequately patched but older Windows 2000 workstations, is
tcp 8081. Though nmap shows this as blackice-icecap port I do not find
any such application running in task manager neither is this installed.
nestat-a just lists this port as 'Listening' and does not list any
application name assigned to it, so why is this port there? Who is using
this? I have ran antivirus scan and spybot checker just to rule out any
malware possibilities.
Nessus Scan (tis weeks plugin feed) does not show this port listed
amongst any vulnerability.
Here is the nmap output:
SuSE101:/home/root # nmap -O 192.168.126.245 --osscan-guess Starting
