Stealth mode causing sleep trouble?

Hi,
I have a Rev A. PB 12", and I recently decided to beef up my security, so I checked on all the options under the "Advanced" button of the Firewall pane - Blocking UDP, Firewall logging, and Stealth Mode. It seemed to have worked for a few days, but then yesterday I discovered that the computer would not go to sleep on its own, but only if I forced it to. This really freaked me out because I just recently solved this exact issue with my computer, and it took my a very long time to figure it out, so I was naturally worried again. This time it turns out that if I turn off Stealth Mode, the computer is fine. If I keep it on, it keeps the computer awake. I am not sure why this occurs, and I would rather not have Stealth Mode off, but I want the computer to sleep on its own. Does anyone have any suggestions.? Thanks.

Edit mode causing screen trouble/computer freeze

When I am in iPhoto edit mode, inevitably at some point one or both of these will happen - the monitor screen will begin "mosaicing", starting with small color blocks in random places, and spreading over the entire screen. Sometimes everything freezes and I cannot move or shut down or activate anything, and in either case, I have to do an emergency shut down with the back button - upon restart everything is functioning properly again. The most recent episode, however, took 3 attempts to shut down the mac this way. AppleCare had me do all software updates and a permissions repair from the start-up disc, but this is still happening. Any ideas? Thanks -

Well that's another perfectly good theory ruined by facts!
Try create a new account (systempreferences -> accounts) and see if the problem is repeated there. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.

My ipod touch 4g just updates today on itunes and the update caused more trouble than good. My ipod will no longer show me the battery percentage in the top right hand corner and also I am not allowed to drag other applications to the bottom panel.

My ipod touch 4g just updates today on itunes and the update caused more trouble than good for me. My ipod will no longer show me the battery percentage in the top right hand corner and I am not allowed to drag other applications to the bottom panel. Also my itunes doesn't allow "enable disk use" anymore. Can anyone help? My ipod now says that it's the 4.3.4 version

- Unjailbroken iPod never showed % battery. Just the icon.
- Unjailbroken iPod Touches never had a disk mode.

Contact center desktop Agent stealth mode issue (8.0.2)

So here is the deal.
We're running windows XP and the verstion of desktop agent that i've noted above.
When the agents put the desktop software in "stealth" mode it goes into the systray. However when they receive a call, it takes over priority (only way I can describe it) and does not stay in "stealth".
Has anyone come accross this? Any docs on a solution would be great.
Thanks,
BR

Are you saying that it regains focus (i.e. reopens)? I'm not sure how to interrupt "takes over priority".
Stealth mode should only regain focus if a team message or email is received. If it is doing this for a call it's a bug. From the CAD user guide:
The window appears as an icon in the system tray (lowerright-hand corner of your desktop, next to the systemclock) and doesn’t appear unless double-clicked or if youreceive a team message or an e-mail.
Speaking of bugs, I strongly recommend that you place a PUT order for 8.5 and apply 8.5(1)SU1. The 8.0(x) release is a train wreck and has caused multiple CAP cases.

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.

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?

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.)

Stealth mode is stuck on

Is there a way to reset the ApplicationFirewall? I have a Mac that exhibits the behaviour of being permanently stealthed. It doesn't matter if the firewall is on or off or whether the stealth mode is enabled or not, my Mac does not respond to pings or requests for file/screen sharing. Switching on file or screen sharing causes the Mac to appear in the Shared section of another Mac's finder but clicking on it does not permit a connection. The permissions are correct.
Before the problem occurred, when I connected my Mac to a predominantly Windows network, all of the Windows PCs appeared in my Mac's Shared section in a Finder window. Now I only see other Macs. I can connect to Windows shares using the Connect to Server command provided I know the server's name.
My firewall had this problem before and I solved it by reinstalling OS X. I don't want to go to this length - I just want to bring my Mac firewall back to normal behaviour. It appears something is stuck and therefore I want to reset the firewall back to the factory settings. I cannot find any way to do this.

Are you saying that if you connect this machine directly to another Max with an ethernet cable you cannot ping it?
If so, create a new user account and see if the problem still exists with the new account.
If it does, try resetting PRAM.
If the new account works, then it's a corrupt file in the main account.
Did you ever use any Norton/Symantec software on this computer?

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 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.

Had to start Firefox in safe mode cause it kept crashing after i deleted the file. Now Fire fox Crashes every time I open it and I have to put it in safe mode just to use it, also it's not syncing with my iPad.

If you use Norton software, try disabling your Norton extensions. As of last week, there were severe compatibility issues with Firefox 24.

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.

10.6.2 - Firewall stealth mode

After upgrading to 10.6.2 the System Profiler tells me that the firewall stealth mode is turned off but in System Preferences it is activated. Is this a System Profiler bug or is the firewall not working correctly?

This has been reported before (not in 10.6.2) and has been acknowledged
as a bug in System profiler... ignore what System profiler is saying.
(A search of these forums should find you the other discussions.)
