Detect port scan

do anyone know how to write a java application that can detect port scan?the situation is like this, i can select the ports for monitoring, and when some one scan my port for vulnerable ports, then the system will alert me about the intrusion!the biggest porblem is how the system will detect the intrusion, when the person must know my ip address and port numbers to connect with my pc, and i dun have a specific port number for them to connect to!
i really need to see how a sample of code how this is done!thanks!

CSA 4.0.3 Exempt certain IPs from being detected as source of port scanning

We have an in-house vulnerability scanner that regularly
does port scans and we don't want to see events when the source IP is from the vulnerability scanner.
We tried a network access rule but it dose not work.
1) Network Shim is enabled
2) Network shield rule with Port scan detection is enabled.
3) Global correlation for scans is set to 100 within 60 minutes.
Basically we want to keep detecting port scans except scans from a specific IP.

Thanks Jay for your offer. The thing is NACL does not work in 4.0.x
Here is TAC responce for later versions (4.5.x or 5.x):
"It is possible to do this by changing the field "Commuincating with host
addresses" in the network shield rule. There are 2 ways to do this.
1. Create an exception rule. The exception rule is of type 'Network
Shield Rule'. Make it's action 'permit'. Click Port Scan Detection to
enable it. Include the ip address of the port scanner device in
"Communicating with host addresses".
or
2. Modify the original Network Shield Rule (the one with the deny
action). Next to "Communicating with host addresses", click 'Insert
Network Address Set', and click 'New'. In the new window,name the
network address set. Leave the "Address ranges matching" to and
change "but not:" to the ip address of the port scanner. Then click
'save'. Make sure that the Network Shield rule now contains your
Network address set under "Communicating with host addresses".
We typically recommend using method 1 because it prevents you from
having to modify the default rule set. But pick the method that works
best for your configuration."
I have to find away without upgrading.

Port Scan

i keep getting blocked by a firewall on my website hosting company due to Port Scan. i have tried different pcs but same thing, something from btcentralplus.com is port scanning, it even happened while in a hotel using bt as an isp, any ideas why
root@host21 [~]# grep 86.157.186.xxx /var/log/lfd.log
Aug 29 11:28:04 host21 lfd[28813]: *Port Scan* detected from 86.157.186.xxx (GB/United Kingdom/host86-157-186-xxx.range86-157.btcentralplus.com). 6 hits in the last 20 seconds - *Blocked in csf* for 3600 secs [PS_LIMIT]

Hi paulpa66,
I know this is an old thread, so I hope you are still interested in this, (if you are still a BT customer!).
I'm visiting my parents in the UK at the moment and I am having EXACTLY the same issue as you describe, except I have my own dedicated server in a data centre. I'm actually getting locked out of my own server by my firewall because the CSF firewall was detecting port scans from my parent's BT IP address.
It first happened yesterday and I got my server support people to remove my parents' IP from the block list and whitelist the IP address.
I was working late tonight and at midnight the BT broadband connection dropped out. I ended up power cycling the BT router and the connection came back up. About 1-2 hours later I got locked out of my own server again! My tech support said it was the same problem - port scans from my parents IP address, which had unfortunately changed, so was not whitelisted.
Once it's done it's port scanning it seems to be okay, presumably until their IP changes again ...
This is a real pain!

I've been blocked because I'm port scanning?!

Servers from work keep throwing blocks up on me because they said they have detected port scanning coming from my IP. Before I go any futher, please forgive me for not knowing my macbook pro inside out. I've google just about every combination of phrases and keywords that halfway relate to my issue and I'm still coming up blank. I downloaded Little Snitch to see if I had anything suspicious going out, but the only thing I see, and it concerns me, is "mDNSResponder" hitting about every 4 seconds. it doesn't say there are any actual connections, but something is going on. Under connection stats it says: UDP ports dns(53) followed by a long list of high numbered ports (49411 & up). It also has 2 IP address associated with it, but not sure if that has anything to do with it.
I saw a lot of talk about finding the mdnsresponder.plist, but that file is not on my mbp. I've gone back as far as my time machine allows and don't see that file either. I just reinstalled a fresh OS and I still have this problem.
Thank you in advance for any help!

No PC on my network, but I did install Windows 7 a few weeks ago on Parallels 7. It didn't install correctly, so I uninstalled. I haven't attempted since.

*Port Scan* detected - Blocked by host

Hi all.
I'm having almost word for word the same issue as this person a couple of years ago: http://discussions.apple.com/message.jspa?messageID=8648363.
I am using Cyberduck (but have also used filezilla with the same results) and am trying to download and upload files to my website. My host has blocked my IP a number of times, and has told me that I'm making the server think that I'm port scanning. This is the error that they have given me:
+DENY xxx.xxx.xxx.xxx *in27m 23slfd – *Port Scan* detected from xxx.xxx.xxx.xxx. 11 hits in the last 263 seconds+
As per the suggestions in the other thread, I have scanned my computer and checked security etc. Everything appears to be fine. After installing LittleSnitch, I have discovered that my ftp client is attempting to connect to a bundle of different ports. This is a screenshot of what LittleSnitch showed: screenshot. It got up to about 80 different ports before I clicked "allow all" (at this stage, my host had whitelisted my IP to allow me to troubleshoot, but my IP is dynamic and has since changed, so I can no longer test like this).
On another forum, someone told me to connect using an ACTIVE connection - if I do this, I can download/upload a small amount of files (between 5-20) before it starts trying to connect to ports other than 21. At this stage I have to shut it down as I don't want to be blocked again.
Any ideas? I thought I had this sorted out, but it turned out my host had whitelisted me (I hadn't requested it at that stage), and now that I have a new IP address, I'm back to square one. This started happening about 5 days ago - I have been uploading and downloading files using Cyberduck for over 5 years now, with no issues. My computer hasn't changed recently, my internet connection hasn't changed recently, Cyberduck hasn't changed recently (although I did update it to the latest version this morning to try and fix the problem to no avail), I have changed hosts, but I have downloaded files since then without issue, it's only recently that things have changed.

Looks like I can't edit my original question...
The problem is still happening, I've been doing some testing to narrow it down...
+ it's not just my computer (have also tried from my mums PowerPC and my sisters iMac), although it could be a mac thing (I don't have a windows machine to test from, only windows running on a mac, though I will give that a shot later)
+ it's not my internet connection (although it could be my ISP - I tested at my sisters place, who uses the same ISP as me, am looking for another testing location that has a different ISP)
+ it's not my website (have tried uploading to a completely unrelated website with similar results)
+ it's not cyberduck (have tried with filezilla, similar results, also tried via terminal - I don't know how to upload files, but when I connected, it connected through a different port, a 5 digit number, can't remember what now).
Not too sure where to go from here...

I'm getting a port scanning attack from my iPad?

A while ago, my dad got me an iPad 2, however, he went on vacation shortly after and used it on his vacation.
I'm not sure if it was also happening before he went on vacation, however, ever since I got it back, I am getting popup notifications from my firewall (ESET Smart Security 5 Firewall) that there is a port scanning attack coming from 192.168.1.7.
I logged in to my router via 192.168.1.1, and on my connections list it shows my iPad being 192.168.1.7.
What the heck is going on? Is this a bad setting from my iPad, or is it possible (somehow, I don't know) that there is some sort of virus/bug with my iPad?
I switched my ESET firewall to interactive mode and tried to connect a few times, and set some exceptions for iTunes connectivity, etc, but when I go back, the port scanning message keeps coming up. It is not constant, however it is in random time frames. Sometimes it'll happen once every 10 minutes, others once every 30.
What can I do? Should I try resetting everything to default on my iPad? Is this just a random thing that happens because my firewall is detecting a false positive?
Please help!
Thanks,
Kolgera

It's very possible that either data is being transfered through your router or iPad2 in a non-standard way or some ping requests between the devices has perhaps caused the notification to display. The following ESET Knowledgebase Article should help: http://kb.eset.com/esetkb/SOLN295
If this doesn't help or you're unable to reach the page, you can put in a support case request with ESET Customer Care by going to http://go.eset.com/us/support/contact

Port scan confirmed open ports on my Airport

Hi, I just did a port scan on my out word IP address. This is the add that is on the network side of my AP. I am using an APExtreme Latest version. I thought my settings were secure, but when my portscan showed these open ports I realized it wasn't.
OPEN:
53 DNS (good)
554 rtsp (QTime?)
5009 (bad?)
7070 arcp (QtimeStreaming?)
10000 ndmp (bad?)
Question how do I secure these specific ports?
Thanks you!!

Hi again BD,
+The Router wouldn't be set to DMZ to the Printer by chance would it?+
It's not something I would consider doing, or have on my network. Can something like this be logged? (well, that said why leave a log file that would be detectable?) Or is there a test, maybe a command similar to ifconfig or some such debugger?
+Seems like the Printer must be using Bonjour only to avertize itself.+
I thought I had disabled Bonjour using a suggested method to make an archive of ARDesktop, trash the app and leave the zip in the CoreServices folder. Maybe, something else is directing it to the outward address?
+Can't you set the Printers IP to a Static Local IP? in the same range as your Router+
Well I tried that but the "enter" command remained grayed out in spite of verifying the printer address. I believe AirPortUtility has an automatic function, at least I remember, when I set up the printer a few weeks ago, the process being transparent. It did all of the work for me. Since I started having problems, though, nothing has worked.
Well, if you have any ideas or you see something out of place let me know.
Thanks!

Symantec reporting port scan

I've received a couple of alerts from Symantec anti-virus on a server and client computer saying that it is being port scanned. I was wondering what a network administrator would do about these warnings? Should I just setup a wireshark capture on the computer and see where the scans are coming from or is there a better method to detect devices in your network that are port scanning?
Thanks for the advice

The it reported to port scans?
1 From the WLC
1 From an LAP - If the LAP was not associated to the WLC how do you know it was a LAP?
How often do these alerts trigger?

Port Scan with Network Utility

I'm a little confused by the results of a port scan I just completed using Network Utility. With ARD checked in the Sharing Services pane I believe that ports 5900 and 3283 are opened but while the port scan revealed that TCP 5900 was opened there was no mention of 3283. Could this be why I'm having trouble Observing and Controlling a remote machine? I have also checked all Access Privileges for ARD.
Hoping someone can throw a little light on the subject.

Thank you JD and Dave for your responses.
I've moved on a little since my post of a week ago and although I still can't work out why the Network Utility port scan didn't detect 3283 I have been able to connect to and Observe and Control a remote client on my small LAN. I have two machines connected through a Linksys router - one connected with airport and one directly connected with ethernet.
On the Admin machine (machine A) I have four accounts: New York, LA, Chicago and Miami.
On the Client machine (machine B) I also have four accounts: London, Paris, Rome and Berlin.
The main account for machine A has been New York and for machine B has been London. I have been unable to use the Observe and Control feature from New York to London although all other services are available.
As a test I opened three other accounts on each of the two machines and discovered that I could Observe and Control using any combination of the new accounts but still not the original New York account. I have also connected to machine B using a dns service address so this tells me that port forwarding on the router is configured correctly.
I believe there is probably something in the configuration or preferences files of the New York account which is preventing me from connecting to any of the other accounts on machine B. The error message I get when trying to Control or Observe is "Connection Failed to Machine B".
Any thoughts on the matter would be greatly appreciated.

Issues with McAfee IPS and HP PhotoSmart Premium C309g-m performing port scan

Trying to run a HP PhotoSmart Premium C309g-m printer wirelessly and connect to a laptop computer with Windows 7 32-bit operating system. Printer is available for about 3 and a half minutes and then is blocked by McAfee because the printer is trying to perform a UDP port scan. The IP address of the printer is blocked for 10 minutes and then becomes available again. After about 3 and a half minutes, the printer IP address is again blocked by McAfee IPS for 10 minutes and the cycle repeats again. Goes on all day. Difficult to get any work done. Anyone have a fix to stop the port scans? Thanks

Hello JWB46,
Welcome to the HP Forums!
I understand when you scan a document, it takes longer and the background is black with horizontal white lines or a greenish background. I will do my best to assist you! First, I need to find out your operating system on your computer? Windows or Mac?
How is this printer connected? Wireless or USB?
Please make sure you have followed this entire HP document on Color or Brightness Level of Scanned Image is Not Correct. I would like to test out the hardware within your printer. Try copying a blank document on the scanner glass. Let me know if you have the same results. I will be looking forward to hearing from you. Have a great night!

My MBP is port scanning, and I dont know why!

Ever since this Tuesday at the office (we're all running macs) the internet keeps going down.
I called the ISP, they told me that one of the machines looks like it has a virus running, one of them is port scanning- and that overflowed the router and froze it.
Turns out its my personal MacBook Pro that matches the IP address he gave me. I was FTP'd into a server and downloading a website for backup.
He said something like ports 4400- 58,000 were being scanned sequentially and that it seemed like there was a virus on the computer, I was shocked- and told him that we were all on macs. Perhaps the FTP client (called "fetch") failed to connect to one port and tried another and another ect. But, the tech guy also said that it wasn't on FTP protocol.
Today I've been working on securing my machine. I stopped using the Wi-fi, turned on my firewall ( I know, bad idea to not have it on ) and installed ClamXav and Little Snitch.
Perhaps I have some kind of malware? Is it too late?
Help!

Isp's always blame things on the mac when they don't know why something is happening to their network.
You could launch Activity monitor and look at all the processes that are running. Sort it my cpu cycles. There could be an application stuck in update mode or one trying to phone home..like adobe updater.

Port Scan is shooting blanks

I am finding it painful to set up VPN so any help anyone can give would be real generous.
I have been trying to connect to a VPN to tunnel L2TP via IPsec over port 1701 and PPTP over port 1723 but having no joy at all.
Macbook (10.5.6) uses mobile broadband USB modem (dynamic IP and telecom APN settings) to access internet. Internet works great, but have been unable to push thru VPN – getting the same error message "Connection terminated by communication device". I've checked firewall settings and it is set to allow all incoming requests. Therefore, there should be no ports blocked.
However, when I check open ports using Port Scan in Network Utilities using my session IP address the results are empty. All I get is the following:
Port Scan has started ...
Port Scanning host: 193.120.116.180
Port Scan has completed ...
Why is this not working? I'm confused
Am I able to check open ports on my Mac using dynamic IP address within active session on my Mac?

I am trying to set up connection to PureVPN for security purposes and have followed their config settings for my Macbook.
So how do I check the ports on my machine, as I'm sure it's not a problem at their end. I only have one machine so don't understand how it is possible to see if ports are being blocked at my end.
Do I run that /var/log/ppp.log in Terminal?

Is this port scanning?

Hello all,
I’m a new Oracle Administrator and I want to ask the following question:
I have one 10g R2 Database Server (myhost.mydomain) running a DB with SID=DB1 on a Linux Redhat Server.
There is another 10g R2 Database on a Win2003 server (HOST1) which through a database link is doing specific select on two tables only (I am not responsible for this server).
Looking the listener.log of my server I saw that every 10 – 20 seconds there are connections on my server and on different ports. Is this something like port scanning?
A 10 minute sample of my listener.log:

Is this port scanning?No. Port scanning is sending various crafted tcp packets to a range of ports to determine what, if any, service is using that port as a listening end-point. It is not about sending lots of packets to a single port.
So if someone port scans your Oracle server, there is an excellent likelihood that you will not even see that. A stealth scan is commonly used - and this will be dealt with at IP stack level and not at the listener level. So the listener will never see the port scan. It will not be recorded in the listener's log.
What you are seeing are standard client server connections. The server port is 1521. The client port will be a brand new port each time - and a port number from the private/dynamic port range.
A lot of client-server connections to a server that for example fails, can be a sign of a DoS (<i>Denial of Service</i>) attack. But yours simply seems to be the local Oracle instance checking in with the listener at regular intervals.
The executable according to the connection string received from the client is <i>d:\oracle\product\10.2.0\db\bin\ORACLE.EXE</i>. This means an Oracle server process. An Oracle instance will continually contact the local listener to inform it of the services that it supports.

How to report possible Port scanning and DOS/Fraggle Attack??

I have been experiencing lag while surfing the internet. One temporary solution was to get a new IP from VZ but this fix was short lived. So I became curios and dtarted to log connection attempts to my router and noticed what I saw resembled port scans and even a Fraggle/DOS attack at times. I am posting my routers log below and would like to kno how to go about reporting this abuse and what I see as malicious activity?

You're getting hit from IPs from everywhere, so there's no true person to ask in regards to this. Whoever had your IP last was probably up to no good, or it's possible for some reason your IP was targeted. Might also be possible that whoever had your IP last was running servers. My Dedicated server gets hit with this nonsense all the time. Sometimes it's an issue with someone trying to DoS one of the game servers I run on it. Causes lag for only a few seconds before the hardware firewall in front of the server kicks in and handles the rest. China I actually wound up blocking access to entirely for a month or two since I've hardly seen anything that wasn't a port scan or an SSH/FTP hacking attempt.
A few of those IPs are owned by Google and Microsoft, which implies there was probably an HTTP server at one point running on the IP you're using now.
