Unusual port (8081) is open?
location: ubuntuforums.com - date: July 3, 2010
I did a port scan on my own network and found the following port open on my Ubuntu:
PORT STATE SERVICE
139/tcp open netbios-ssn
445/tcp open microsoft-ds
2000/tcp open cisco-sccp
2001/tcp open dc
2004/tcp open mailbox
3000/tcp open ppp
5900/tcp open vnc
7200/tcp open fodms
7201/tcp open dlip
8080/tcp open http-proxy
8081/tcp open blackice-icecap
24800/tcp open unknown
Particularly, I have no idea what/why the following is open:
8081/tcp open blackice-icecap
Quick google search didn't reveal anything particularly useful, anyone else want to chime in?

port 22 open, trying to close it
location: ubuntuforums.com - date: March 13, 2011
Hi all, my default keying popped up and asked for authentication twice today, odd since I wasn't doing anything that would require it. I have a wifi network that does require authentication, but the wifi device on my netbook was turned off at the time.
Nothing failed to work or stopped working after I twice refused to authenticate the keyring.
I'm new to this so feeling my way... I ran nmap:
sudo nmap -sS -O 127.0.0.1
22/tcp open ssh
Looking in /etc/services I found:
ssh 22/tcp # SSH Remote Login Protocol
Once I stopped freaking out, I got back to googling and tried to find out what process had the port open:
sudo fuser -u 22/tcp
I opened system monitor and could not find a process 543 so I tried:
sudo fuser -k 22/tcp
but this simply results in a new process starting which keeps port 22 open.
I deleted remote desktop off th
Why is my port 25 open?

I played around a little and found that out:

Do you know why I have a postfix installed on my system? This is not default, or is it?
On my other laptop (Ubuntu Netbook Remix 10.04) the port 25 is closed.
Thanks in advance,
TCP Port 53 Open How to enable UDP 53?
location: linuxquestions.com - date: March 15, 2005
Hi all, I am setting up a new web server (a first time experience for me with a dedicated clean install) and I have my bind configs sorted - name resolution working internally and for external lookups. But domain transfer has not worked.
I suspected port 53 blocked but with nmap found it open - but that was only TCP as I eventually found after some hunting and noticing this in my secondary and external DNS server (a trusted friendly server)
[myip]#53: failed while receiving responses: permission denied
It seems that bidirectional UDP port 53 and unidirectional TCP port 53
from secondary to primary is needed to effect domain transfer and get things really running...
So how do I enable UDP port 53 on my Debian Sarge server?
I am guessing it is default closed on the firewall and being new to these security measures and configurations I don't know where to start..
I have done a bit of a search on firewalls and 53 and UDP and got some useful hints bu
Apache2 not working, port 80 open on router, no access from outside of LAN, help?
location: linuxquestions.com - date: December 5, 2006
I'm running apache 2 on Ubuntu Edgy Eft, and my router is configured to open up port 80.
My computers IP is 192.168.1.34
And whatismyip.com says 220.127.116.11 or in other words my routers IP.
Now when I run http://192.168.1.34/ everything works fine, but since I want my site accessed from outside I need people to access the http server from 18.104.22.168 , but when I run http://22.214.171.124/ I get no connection, even though my router has an open port 80.
So I'm wondering, do I need to configure my computers port 80 and connect it to the routers port 80 somehow?
Or could it be something else, what could be the problem?
I'll get any further information if nessaccery.

Do I need port 5900 open for VNC if I tunnel it through SSH?
location: ubuntuforums.com - date: July 15, 2011
Apart from the security benefits, does using VNC as an SSH tunnel mean I only need to have SSH's port 22 open?
Any input would be appreciated!
nmap shows port 80 open on WAN IP scan.
location: linuxquestions.com - date: June 16, 2006
I'm trying to figure out why nmap shows my port 80open. The only port I've specified to be open/passing traffic on my router is a random ssh port in the 2000 range. Here is a scan of my nix box. And a scan of my WAN IP. Do you think this is normal? I'm assuming the only reason the scan shows port 80 open is because I'm forwarding the port to my laptop/nixbox for the ssh session. Do you think this is normal for port forwarding to have port 80 open? Thanks
What port to open for RTCW?
location: linuxquestions.com - date: November 26, 2003
I am running Return to Castle Wolfenstein on my RH 9 box. When I turn the firewall off, it runs fine. With Firewall on, I get a no connect error when hitting RTCW server. How can I find out what port(s) Wolf needs open? I do not want to leave firewall down.
