Stealth mode attempts slowing adsl connection or killing it!

G'day,
I found this topic in another thread somewhere in here, but for some reason it was closed down. :confused:
For the last two weeks I have found in the Console log that I have been getting stealth mode and UDP communications attackes when I hook my P/Book up to my wireless network via A/port Express which is linked to my A/port Extreme Base Station. I have set up the Firewall to detect stealth mode attacks, block UDP communications etc., and when I get these attacks it is either drastically slowing my net connection down or causing me to lose connection altogether.
What can I do to stop these attacks from killing my ADSL connection?
I haven't installed any secuirity updates as I'm very wary of them killing my Macs, as they have done in the past.
This situation is really pinging me off big time and if anyone could help out I'd be really greatful.
Thanks in advance for your help.

Stealth mode attempts

I seem to be getting a lot of messages in my Console log about:
11/15/10 10:17:22 PM Firewall[61] Stealth Mode connection attempt to UDP "numbers here" from "numbers here." I took out the numbers because I don't know if it is safe to post them.
It just seems a very high number of hits.
I connect to an AEBS to a cable modem.

Ipfw: Stealth Mode connection attempt to UDP...

Hi all,
I recently encountered internet slow down at home. I connect to internet using a wireless router, which has been used for almost a year without any problem. The router has WEP setup and MAC address filter enabled.
When I open the firewall log, I found that my router is keep using different ports (from 6355 down to 2063), trying to connect the port 137 of my Mac Mini. I have checked that port 137 is related to NetBIOS. The following is extracted from the firewall log (with my host name masked).
May 18 00:46:54 ------- ipfw: Stealth Mode connection attempt to UDP 192.168.2.2:137 from 192.168.2.1:2058
May 18 00:47:03 ------- ipfw: Stealth Mode connection attempt to UDP 192.168.2.2:137 from 192.168.2.1:2059
May 18 00:47:06 ------- ipfw: Stealth Mode connection attempt to UDP 192.168.2.2:137 from 192.168.2.1:2059
May 18 00:47:18 ------- ipfw: Stealth Mode connection attempt to UDP 192.168.2.2:137 from 192.168.2.1:2059
May 18 00:47:28 ------- ipfw: Stealth Mode connection attempt to UDP 192.168.2.2:137 from 192.168.2.1:2060
May 18 00:47:30 ------- ipfw: Stealth Mode connection attempt to UDP 192.168.2.2:137 from 192.168.2.1:2060
May 18 00:47:42 ------- ipfw: Stealth Mode connection attempt to UDP 192.168.2.2:137 from 192.168.2.1:2060
The IP address of my router is 192.168.2.1 and my Mac Mini is 192.168.2.2. I have checked from the router administrative page and can't find any other machine in my wireless network. I have no idea what's wrong with my router. Any idea please? Thanks for any advice in advance.

Hi Rick,
Thanks also for your response.
Do you have a network printer? (make, model, please)
Any other network devices on this LAN (Xbox, printer,
PC :o
I don't have a network printer. The little network only consists of the router and the Mac for the time being.
Do you have uPNP enabled on your router?
What make/model of router? (there may be something
common to this mfr)
No, the uPNP is never enabled. My router is Belkin Wireless G Router (F5D7230-4), which is supposed quite Mac-friendly in the market...
You say you still get the logging, even when the DSL
modem is disconnected. Weird.
Yes, it is weird.
StealthMode has been known to cause more paranoia in
some users. This 137 port scanning might be coming
from a printer or other network device on the inside
of your little network...with stealth disabled,
things would just work the way they're supposed to --
quietly. Your mac is probably secure. Your router is
probably secure (especially if you changed the admin
password when you set it up. If you've been using the
default admin password, then shame on you <wink>
I have enabled Stealth mode in my Mac. Sorry to let you down (^^V) that I am not using the default password before the discovery of the port probing mentioned and have changed to another one after reset and firmware upgrade as advised by the other poster.
Am I off-base here, fellows?
Nope, you're appreciated for any idea trying to help.

Have I been hacked??? "Stealth Mode connection attempt to UDP"

My Mac Mini has been running very slowly lately. Sometimes it takes half a minute to switch between apps, and I mean simple apps like Mail and Safari and Appleworks, not Photoshop. Photoshop is a joke it runs so slow. So I've run Onyx SEVERAL times, restarted and cleared my PRam, and nothing is helping. I also noticed it seemed like my Mini was "running" a lot (the hard drive making a noise like it was up to something when I'm not doing anything). So I looked at the cable box and the Ethernet light was flashing softly, going along with the hard drive noise. Then I downloaded something called MenuMeters and it is showing that I'm receiving data constantly - it goes between about 300B/s to 1500B/s, and sometimes it shows I'm sending too. So I opened up the System Preferences and found out that "Network Time" was enabled in the Firewall preference pane. I unchecked that but my Mini is still receiving. (I'm not on any Ethernet network or anything either.) So I opened Advanced and found that the "Block UDP Traffic" box is not checked, though the other two "Enable Firewall Logging" and "Enable Stealth Mode" are checked. THEN I opened the log file and was shocked to see 1048 lines, mostly reading ""Stealth Mode connection attempt to UDP," although once in a while I saw a few that said "12190 Deny TCP." And that 1048 is just for yesterday and today. Is that normal??? Sometimes the "Stealth Mode connection" lines are single (I mean, not to a repeating number), but sometimes they repeat two, three, even five times to the same number.
Have I been hacked? Is someone stealing our small business data? Sounds kind of ridiculous, but can't help and worry some. Or do I have a virus? I tried to google whether or not there are any Mac viruses out there, that might pertain to this, but couldn't figure out anything. What do I do? I'm not very computer savvy, other than running my apps, and don't anything about Terminal or things like that. Even as I type this MenuMeters is showing me I'm receiving SOMETHING. Yikes!
Mini Mac OS X (10.4.8)

You mention one of the applications you have been using is Appleworks - which is not supplied with Intel systems, only PPC Macs. This would tend to suggest that your mini is a G4 model. It would be helpful to know which model the system is, what software you have on it, how much free space you have on your hard drive, and what you typically use the system for.
It's interesting that you note the system seems generally busy, which would go some way to explain why it may also seem rather slow, but you haven't mentioned whether you've run Activity Monitor to see what processes are active when the system seems to be active with some task that is not of your doing. If you haven't tried this yet, do so now - and let us know what processes the system shows as active when otherwise the system ought to be idle.
To answer a few of your broad questions: When the system is connected to the internet, it's not unusual to see a certain amount of data through-putting the network connection, but in most instances this would be in the region of 100-200B/s, with occasional, brief, spikes upwards of that. In the absence of a local router that level of data is likely to be higher, since basically your Mac is managing your internet connection and maintaining a public IP address assigned by your service provider. In a system with a router, the router handles this traffic so the resultant volume of data the Mac sees would be less.
The fact you see entries in the log of the sort you describe is not necessarily an indicator of a problem. It may suggest that the system is being probed, which as Boece has said is not at all uncommon for a system with a public IP number - and is indeed why it's most common to find systems being used 'behind' a router. The router takes the public IP number, and so systems behind it are given internal addresses by the router which are not visible to the outside world. The Router then performs something called Network Address Translation (NAT) which converts internal and public addresses as needed to ensure the computer can communicate with the internet while still staying 'invisible'.
In your position, I would look to add a basic router between your Mac and your cable/DSL modem because a hardware firewall is generally more effective than a software firewall, and NAT will keep your system clear of most potential hacking risks.
As for the potential for a virus - this is a bit of a thorny subject because most will (rightly) say that MacOS is not the target of any known virus that exists in the wild. Unfortunately, that doesn't mean that it will remain that way, or that it's impossible to create malware that can infect or impact Mac systems. A good line of defense can be obtained by downloading and installing ClamXav (http://www.clamxav.com/) and setting it to examine vulnerable spots such as the desktop where files are typically downloaded or your mail folders, and using it to scan the system. Generally speaking, unlike antivirus products for Windows, this software does not consume copious amounts of CPU time (it grabs between 1 and 5% on my 1.25 G4 mini while in the background) so it's worth having around.
You also mention running OnyX several times - this is not a good thing. OnyX, like the other utilities of this type, is a useful tool in resolving performance issues, but if you find that it doesn't work when you use it once, it indicates the problem is not something that OnyX can resolve. Running it multiple times doesn't necessarily do any harm, but it does mean that macOS is continually having to build new cache files etc, which makes the system run very badly!
So....
(1) tell us about your system, the software on it and what you use it for.
(2) how much free space is on your hard drive.
(3) run Activity Monitor and tell us what it shows when the system seems to be busy doing it's own thing.
(4) download ClamXav and run it as described.
(5) get an inexpensive router and insert that into your system as described (we can help explain how to set everything up once you've got it if you need assistance).

Stealth mode connection attempts? Reason for Open DNS in router settings?

Console is giving me repeated messages (many times per minute) that read
"Stealth Mode connection attempt to UDP xxxx from 208.67.222.222:53"
That's a little scary to the uninitiated! I've done some rummaging here and across the net on this. I understand little of what I found or how to stop this. I understand that the 208.67.222.222 is Open DNS related. I was glad to discover that as I originally thought some malicious computer somewhere was trying to gain access to my MacBook Pro. I thought I'd delete the DNS servers to see if that would help, but they are greyed out in the Preferences--Network--DNS panel and cannot be removed.
From what I've investigated, those Open DNS servers are set in the router. I know how to change or delete those, but maybe I shouldn't. In fact, maybe someone can remind me why I put them in there in the first place (years ago). I vaguely recall some advantage to using Open DNS (faster?), although I'll confess that, of late, too often mistyped web addresses go to an Open DNS page, which is a nuisance.
In any event, I'd like to do something that would stop the stealth mode "attacks". While I'm sure I could ignore it, maybe it's eating up some browser or network time. It also seems odd that it would go on and on!

Thanks for some info on this. Should I only see it then, when I'm in a browser? Or, when wi-fi is on? I'm assuming that the Mac may be checking what time it is, although it seems a little too frequent for that! (3 times a minute? Well, maybe that's about right, but then Apple and Open DNS should coordinate so that this message doesn't show up.)
I did find this: http://forums.opendns.com/comments.php?DiscussionID=1785
Does that make sense? It's completely benign? And doesn't waste CPU cycles?
One problem with all this stealth mode logging is that it fills up the Console message window! It thus means that there is gobs of stuff I have to wade through to see if there really is something going on from the outside!
I did find two oddballs in there (I don't think they were open DNS as they weren't 208s), so the firewall is doing something.

Firewall - stealth mode connection attempts from AEBS to computer

Console log is packed with Info messages realted to connection attempts from AEBS router. Is that normal?
also, system profiler states: Firewall Logging: No / Stealth Mode: No. Why the discrepancy?

I suggest not taking Mr. Lambert's "bad design" commnets too seriously.
AFAICT, the string "bad design" does not appear in the post I referred to. Please do not chastise Terry Lambert (whoever he or she may be) for someone else's sins. If anyone said 'bad design', it was I.
he seems to have confused the IP addresses of two different network devices (his Mac & his Airport router) & suggested loopback
No, he didn't; you misunderstood. What he is saying is that his network device (Airport, or, en1) is talking to itself through the router instead of through loopback.
He also seems to have concluded that UDP's lack of a handshake protocol makes it a "connectionless" protocol, which makes no sense
Terry Lambert was correct; you may have misunderstood the technical term in question. For instance, a quick look in Wikipedia reveals that,
"In telecommunications, connectionless describes communication between two network end points in which a message can be sent from one end point to another without prior arrangement. […] Internet Protocol (IP) and User Datagram Protocol (UDP) are connectionless protocols." (The stress is mine.)
But Wikipedia is not always to be trusted. We are not a bunch of techies here, so I'll turn to an easy, plain-language reference:
"A connectionless protocol doesn’t go to the trouble of establishing a connection before sending a packet. Instead, it simply sends the packet. TCP is a connection-oriented Transport layer protocol. The connectionless protocol that works alongside TCP is called UDP." (The stress is mine.)

After attempting to update to ios 7, my iphone is stuck in recovery mode and will not connect to the itunes software server.

After attempting to update to ios 7, my iphone is stuck in recovery mode and will not connect to the itunes software server. I have already tried the resetting with power swich and home button and plugging into computer but it says the "iPhone software update server cannot be contacted." I am locked out of my phone. Does anyone have any idea how to resolve this issue and get the phone working again. I will add that I am now trying to restore it on a different computer with a lower version of itunes, but the computer that it initially happened on had the updated itunes and gave me the same result ... nothing. Thanks for your help in advance.

Try going to recovery mode as described here. You may have to try this more than once to succeed.
Use the original iTunes that the iPhone synced with.

Is there any way to set a stealth mode on the ports in Panther

The built-in firewall in Tiger provides a 'Stealth Mode' setting that makes the ports nonresponsive to external attempts to connect. The Panther firewall doesn't have this capability. Does anyone know of a way to enable this on a Panther machine (specifically 10.3.5 & 10.3.6) - even if it involves installing a utility application is ok.

Ok, question for Karl.
When I go to https://www.grc.com/x/ne.dll?bh0bkyd2
and do the ShieldsUP Stealth test from outside my hardware firewall connected directly to the internet (SSH turned off for the test) why do I get this result?:

Stealth There is NO EVIDENCE WHATSOEVER that a port (or even any computer) exists at this IP address!
The only thing that fails is the PING test. Because they can ping my address. I don't have firewall turned on and I am running 10.3.9 not 10.4.
Any ideas? Is this test just not thourough enough?
Run the test for yourself and see. You will need to click Proceed at the bottom of the page to start the test.

Please help.
Sincerely yours,

The "crashing," whatever you may mean by that, has absoutely nothing to do with these stealth mode connection attempts, which we all get. When in stealth mode your computer is invisible to any connection attempts like this. You are behind a firewall. No one is attacking your computer.
FYI:
You should, instead, be looking at the crash logs or kernel panic logs, if you got a message to restart, and trying to determine just what was happening when the crashing occurred. You should also explain what you mean by "crashing." Just what was happening?
Looks like you have parental controls set up for this account. That's what all these "denys" from Keychain are reflecting.

Stealth mode logs in ipfw.log

Every so often I get logs like this in my /var/log/ipfw.log:
Jan 20 08:41:33 PowerBook ipfw: Stealth Mode connection attempt to TCP 10.0.1.x:53725 from xxx.xxx.xxx.xxx:80
These log entries do not show an ipfw rule number. So how can I tell which rule from ipfw is causing them to be logged? Are they being logged before matching any of the rules you see on the command sudo ipfw show?

yes i am sure. This are the exact words... "The iPad "iPad" could not be restored. The disk you are attempting to use is full. (Removing files and emptying the recycle bin will free up additional space". i tried some options, hard reset, redsnow, tinyumbrella but still it's stuck.

Windows 7 Ultimate (64-Bit) fresh install, only WLAN and video driver installed but EXTREMELY slow internet connection...

I recently checked my internet connection on my Asus G53SW and found that it was extremely slow on both the LAN and WLAN connections. I checked with a different laptop (old HP Pavilion) and I get a steady 74mbps+ connection using the same LAN cable and
also with the WLAN connection. My ISP has checked their side and everything is fine.
To try and resolve the issue I tried uninstalling, disabling and tweaking various software and even tried safe mode with networking, all to no avail. I then decided to do a complete fresh install this afternoon. I have installed Windows 7 Ultimate (64 bit)
successfully onto my SSD and everything went smoothly. I have now only installed Nvidia video drivers and the (only) WLAN driver from the Asus support site.
My WLAN connection remains incredibly slow (amost half what it is on the HP and my MacBook Pro). Clearly this is an issue with either the Asus laptop or Windows but I don't know how to proceed in order to eliminate which it could be other than to try a different
o/s to W7-Ult.
Can anyone help who knows more about this than me? Perhaps someone who has had a similar or the same problem because this is giving me a severe headache!
Thanks in advance to all and for any advice.

Thank you for responding. As I stated in my original post the reason I went through this process was because of an extremely slow internet connection from both the WLAN and LAN connections on my G53SW. At that time I had all of the correct drivers on the
machine. Whilst I would agree that with the machine only having a video and WLAN driver it may well not be working 'optimally', the rationale for doing this was to get the machine working with the minimum of processes to show that it was not anti-virsu software,
Steam or the like causing interference.
I have changed out both of the HDDs this evening (a primary SSD and a secondary 1Tb HDD) for a clean hybrid 1Tb Seagate drive. Once I have installed all of the Asus drivers (and nothing else) I will try the speed test again and report back.
I can now report that with a fresh install of Windows 7 Ultimate SP1 and ONLY Asus drivers as supplied the issue remains. On a connection where I should see around 75mbps I am actually getting around 18mbps, sometimes considerably slower. This only affects
my Asus machine.

Slower internet connection when connection wireless network

Currently using a Linksys WRT54GL wireless broadband (firmware v4.30.5) router in conjunction with a Thomson Speedtouch 546i ADSL router (ISP provided).
My problem is that when I connect to the internet over the wireless network I experience a much slower internet connection in comparison with when I use a tp-cable.
Tested with various online "speed-tests" (I know they are not to be trusted, but they do give a basis for comparison):
Over wireless network : ca.6000kbits/sec.
Direct cable from pc to router (tested on both routers):12-13000kbits/sec.
Hope anyone has any idea what the problem may be, and any help is greatly appreciated.

Change the beacon to 50 ....and reduce the RTS and the fragmentation by 40 each.....these options are found under the advanced wireless settings...
Also make sure that u have the latest drivers installed for the Wireless NIC.

WiFi *really* slow to connect on wake

I recently moved to a new neighborhood and now my wifi is really slow to connect when I open up my MacBook from sleep mode.
My old place had other networks in the vicinity, but about half as many as there are available at my new place.
Either way, its really becoming a pain, as I have become very used to opening my MacBook and being instantly online.
I have power cycled my router and modem and done everything short of resetting the firmware.
I am using a standard Linksys WRT-54G and it's served me fine for years, as has this MacBook.
Any ideas on how to remedy this?

How long is this "really slow"? Several minutes?
You may want to look through System Preferences>Network and take a look at the "advanced" options for Airport. Might be worth clearing out all preferred networks and get those reset.

Stealth mode attempts slowing adsl connection or killing it!
