Wired/wireless traffic general question

I originally set up my Airport Extreme without much expertise on WiFi or routers, but I want to raise my knowledge base now.
My current question: In general operation with both ethernet and wireless clients, obviously all the traffic with wireless clients is broadcast over RF to anything out there that can receive them, but is any of the traffic between the base station and the ethernet clients also broadcast over the RF signal? To put it another way, can eaves dropping on the RF traffic also allow eaves dropping on the ethernet traffic?
Are there any good educational books like a Missing Manual or such on WiFi or Airport?

A lot of very interesting aspect of "others experience w/airport". I'm also in a suburb w/a lot of WiFi, other variation's of the same, and Airport traffic. One early concern I had was the Rf-AP system starting up, as it does right out of the box. Not knowing this, (at least at first) was for me an embarrassing wake-up call. As for near-by WiFi/and other "dish, etc" systems, A few thing's I noticed, and thanks to associate's who know WiFi/Rf tech very well, a few observations, for what it's worth. Regarding "Ghosting" of certain signals, it is almost inevitable for many reasons. It's a bit like (usually and harmlessly) being at a crowded party, where you "hear" many people jabbering away, but don't really know "what they're saying, other then 'something."
Oddly enough, I have an associate who calls that (a bit like a cheap hearing aid) "Rf, or harmonic din". As for it being problematic from a security point-of-view one needs to isolate "sections" from one "broadcast" which I'm told is rather low tech, as a first step to having one "borrow your specific signal,' for say either sub-Walmart (cheap bas******) access to the net thanks to your WiFi AP. As you mentioned, w/so much depending on the chronic pain that's all based on passwords, well, we know the issue w/that.
Several aspects of trying to maintain some dignity in not getting hacked for whatever intent present repeated problems. I was hacked, and it was (unfortunately not benign). Believe me. Since , I have done everything short of active EW suppression (FTC, and anyone in range would be understandably ******-off.) Your comment about "flat signal strength" I'm told is screaming, "I'm blending in, move on." Varying sig strength is one way to blend in yourself, but only a bit.
But WiFi signal structure has certain quiescent properties reported in the literature (I read it on physorg.com, or technology review I think) that makes that soft engulfing-Rf nature of WiFi useful, Ex: for those who want to know, or really just be aware "someone, a pet", etc; who is moving around a room, compared w/the stuff in a room, building, etc. That attribute provide's a technical/mathematical yardstick that is at least one reproducible and exploitable aspect of the technology. As with that noisy background "party din," it's why noise in general can be cut through as long as you get even a small piece of a conversation.
I've looked at passive material "blankets" that smother Rf. Certain conductive polymer's woven in the density of a gym mat are somewhat useful if its something serious enough. Naturally, (pricey) and by no means perfect. Beyond that one can use old power company techniques developed to know where a line goes down, for example if using a hard line. Since ac can be modulated, it can also be run through what looks like a small old desk-top pc cpu tower. ****, anyone can buy a plugin, looks a small 120vt-12v transformer you plug in the wall ac, and that turns ones household wiring into a local, house/office Rf wireless network.
In the end it can get surreal, silly, paranoid. or just sad. Been there too. Anyway, best of luck. Bob.

EAP-TLS Wireless Authentication - General questions

Hi,
I want to use EAP-TLS as a method of authentication for users/computers to join the Wireless. Devices that will connect to the Wireless are part of the domain.
What certificate is preferred to use for this purpose? Computer o User certificates? I guess that it probably depends on what you want to identify or authenticate, a user or a device, but what option is “generally” recommended?
Is there any difference from the point of view of security? Is a computer certificate more secure than a user certificate o vice versa? I have been told that user certificates are easier to compromise (or steal from a windows machine) than computer certificates
even if a user doesn’t have Admin privileges in their machine?
I have also been told that using user certificates could result in some issues to pass some Compliance audits.
I would like to be sure that the design complies with the most recommended and secure alternative.
I would appreciate some help.
Many thanks.

There are pros and cons to using workstation or user based certificates, as well as benefits to using "both". But first thing, both user and computer certificates are secured in the same way in the operating system - in an encrypted state. There are reasonable
controls in place, but anyone bent on hacking a system and has physical control of it, has many options available to them. Things like Bitlocker with TPM can help mitigate many of these attacks. The purpose of certificates is to increase the security and integrity
above passwords. It's not foolproof.
The benefit to using computer/workstation authentication is that when the computer boots up, it joins the WiFi and enables domain users to log on. This is even the case if the user has never logged onto the computer before. The workstation has a secure channel
to a domain controller and is fully managed and applies GPO updates. In this model, the WiFi connected machine is no different from a wired machine.
The disadvantage is that you need to carefully manage your computer devices in AD. Imagine the scenario of a laptop that is stolen. Do you have the means to know which computer object it is and to disable/delete it from AD? If not, then whoever uses the
computer will be able to get onto your WiFi. Many organizations have trouble with this aspect.
User Authentication is a little easier as its easy to manage users who should be allowed to get onto a network. If they leave, their account is disabled. However, they must have cached credentials on the laptop
they want to use as there is no means to contact a DC to authenticate a user the first time.
Another option to consider is to use BOTH. In this scenario, you issue certificates to both the computer and user. When the computer boots, it joins the WiFi. When a user logs on, the computer stays connected
to the WiFi for 60 seconds to allow the user to authenticate and to receive their credentials which are then used to authenticate to the WiFi. If the user is not authorized or is unable to authenticate, then the WiFi is disconnected. This provides the best
security option, but it means managing both user and computer objects properly.

Wireless printing - general question

Hello,
I am considering buying a OJ Pro 8000 Wireless. How does the wireless work? Is it only ad-hoc with one PC or does the printer associate with an access point and then is available to entire wired and wireless subnet?
Best regards
FISHRMAN

The latter is the primary purpose and most common installation.
Ad-hoc is also supported, although it is not very reliable and interrupts any infrastructure wireless with which the computer is associated.

Wireless WRT54GS speedbooster question

Hello everyone.
I have a few questions if someone could give me some answers. I'm using Vista Ultimate. I've got to tackle installing the router again since I have a different computer and then I'll have to set up networks to other computers here (3) actually. But I have had my wireless speedbooster for a year and now got to go through the whole process again. My question is why do they call it wireless when you have to plug in cables? What is the wireless part suppose to consist of? Someone came to my house this past weekend and said something about it and it did make me wonder about that.
And how far can you actually set another computer to your network. Is it only in your household location or can you let someone 10 minutes away to network with you or add them on your network.
I tried to search for the wireless question but I couldn't find it and I did go under general question but for some reason couldn't find a new message so I could ask. It's been very aggravating and I didn't remember it being this aggravating before. Also I've read here that I don't have to install the router through the CD. I have tried to do that on these vista windows which I hate and I'm going to install windows 7 over this when I get the chance but I got to tackle one thing at a time. You'll never know if you don't asking tried to connect the router and computer using the CD it goes through the whole thing but never really configures it but then it was very very slow after that so it must have done something. So now it's not even plugged in or connected at all. Ever since I disconnected and connected my DSL back to my computer I have these issues whenever I cut my computer it telling me these message. When booting up 1-"cannot communicate with DNS 208 104 244 45 network diagnosis pinged the remote host with no response". And this message "windows confirmed that primary DNS server is currently online but is not responding windows confirmed that primary DNS server is currently online but is not responding at this time this usually means the firewall is running between the two and computers (I have only one connected at all at home for now!) and blocking the domain. Windows have confirmed that the firewall on computer is confirmed correctly to allow this connection but however a firewall is blocking your connection". Can anyone guide me somewhere or give me links to follow because I have a serious cornea infections and hoping that I haven't lost my eyesight in one eye and I'm not suppose to be on the computer to let my eye rest.
Any help would be very much appreciated very much
Thanks, Harley123

The Router which you have its an 4 Port Ethernet / Wireless Router. Well its not necessary to Hardwired your computer always to the Router. Once your Router is Configured properly, then you don't need to connect your computer, you can use all the computers Wirelessly and they all will be able to go online... Just for an Initial Setup you need to Hardwired your computer to the Router, Once its done then you need to unplug the Ethernet cable from your Computer and your computer should be able to go online wirelessly.
The wireless signals of your Router can go upto 80 to 100fts, Not beyond that. As you have mentioned that you want to share the connection with some who is 10min away from your Place, then its Impossible.
There are 2 different ways to configure your Router, Using the Setup Disk or Configuring all the settings on your Router Manually.
Whenever you connect your Modem to your Computer and if you face that problem just you need to Unplug the power from the Modem wait for 10sec and replug to the power to your Modem and check if you are Online.
Windows Vista has Many issue while connecting to Internet. Sometimes you get all the information on your computer and your computer is properly connected, but the Vista computer doesn't let you go Online.

Wireless Router/Networking question

Could post this in any number of forums here as my computer inventory includes a MDD with wireless card and a Sawtooth connected direct to the ethernet hub which in turn is connected to my Qwest DSL wireless router. Have a couple others wired in as well a cube and a FP iMac 800 (one of the originals). And now my first laptop ... MBP 2.4Ghz.
Anyway, the question is this .... Can I replace the Qwest DSL router with one that provides 'n' wireless speed so the MBP can benefit from it? If so, any recommendations for a router?
Just another sentence about my set up ... The router is wired/wireless. Computers without wireless connect via ethernet, computers with wireless connect wirelessly (of course - duh).
Thank you

Yes, you can do that. The n wireless router will have to run in mixed g/n mode, which will reduce the actual speeds attained on the MBP (lower than an n-only network, but the reduction will not be to g-wireless speeds).
Having stated that, keep in mind that unless you are running local wireless file transfers (think backing up to Time Capsule here), there's no need for n-wireless. In other words, a home wireless network is not the bottleneck for internet access, it's your ISP.
Verizon just announced 50 mbps with their FIOS service (with a hefty premium cost), and that's the fastest available home internet connection, and it's still slower than even 802.11g (54 mbps). Typical home internet connections are in the 1-10 mbps range, and so even an 802.11b network is faster.
Hope this helps...

General question regarding "parallelism" of iPhone execution

I've got a general question and hope somebody can shed some light on this.
While I'm relatively new to iPhone development I've been in software programing for more than 15 years now and have a solid background in Java, C, C++, C# and other languages. I've created a couple of applications for the iPhone, easy and complex ones, some using UIKit, others using Open GL and Open AL. With that said I think it would be fair to say that I know pretty much what I'm talking about.
For those who tend to refer everybody back to the Apple Samples or PDF guides, please believe me, I've read them all.
Here's my "question":
I occasionally ran into a situation where I got the impression that code on the iPhone got executed in a "non sequential" or "parallel" manner even when I did not explicitly created threads. I'm not referring to code buried in a framework or so, I'm talking about code I've written. (English is not my mother tongue, so please excuse me if my explanation might be somewhat difficult to understand.)
I try to give an example. Assume a code snippet like this:
_gameEngine = [GameEngine alloc];
[_gameEngine initSomeStuff];
In my understanding the second statement (the initSomeStuff) gets executed once alloc returns and _gameEngine for sure is a valid pointer. Is that fair to say? I sometimes got the impression that the iPhone starts executing code without waiting that a method returned.
I had similar issues when I tried to show an ActivityIndicator while another method was doing a lengthy operation. Pseudocode like this:
[_activityIndicator show];
[self longLastingOperation];
[_activityIndicator hide];
In code like the one above: Can I be 100% sure, that the hide message is not sent until longLastingOperation returns? I ran into a situation where I had the impression that show and hide got called immediately without waiting until longLastingOperation returned.
Final example:
[self performSelectorOnMainThread:@selector(doSomething) withObject:nil waitUntilDone:YES];
[self nextStatement];
-(void)doSomething {
[self longLastingOperation];
1.) In the above code, I understand the idea is that doSomething will be executed on the MainThread and that nextStatement will in no way be executed before doSomething has returned. Is that true?
2.) doSomething is supposed to run on the MainThread but does this hold true for longLastingOperation, too? Or could it be that longLastingOperation WITHIN doSomething gets dispatched to another thread and doSomething returns PRIOR to longLastingOperation been finished?
This might all sound pretty wired but as I said from time to time I ran into a situation where I got totally confused as to how stuff executes in – or out of – sequence. I helped myself with using NSNotificationCenters etc. but I'd like to understand what's going on in detail and crystal clear here.
Your help is more than appreciated.
Thanks,
R.

It is never safe to assume that any allocation was successful, and while it's incredibly unlikely that you're running into any such situation, it's entirely possible for a formal protocol to declare that a given message send should return immediately without waiting around:
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/Articles/ch apter13_section_8.html#//appleref/doc/uid/TP30001163-CH9-BAJIGHAF
An "impression" doesn't prove much unfortunately, so I'd recommend getting friendly with the debugger to see what's really going on.

Solution to use Airprint across subnets wired/wireless

A lot of companies are trying to figure out how to setup airprint to print
in the workplace, wired+wireless across subnets.
We finally figured it out with some DNS magic and a CUPS server.
I have documented the solution at a live document hosted at
http://sites.google.com/site/iwastepaper/
Hopefully it helps a few folks.
<Edited by Host>

You will want to make sure your APs can route from where ever you install them to the WLC managment address.
How APs find the controller can happen a few different ways:
1) DNS A record
2) Layer 2 broadcast (which you seen already)
3) IP Route Forward
4) DHCP Option 43
5) Manual Prime the AP
Most folks lead with option 43.

if you check the config guide you will explain the other processes.

Remote can't find iTunes on mix wired/wireless network

I am trying to control music from a iMac running iTunes using the iPhone Remote app. I've previously done this successfully with a wireless only network (using the Airport Express wifi to join my existing wifi network etc).
However, since introducing D-Link Homeplugs into my network, I am unable to 'see' the iTunes library from the Remote app when I connect wirelessly to the airport express.
My hardware is configured as follows:-
*Netgear Router (wireless disabled) -> Homeplug power network -> iMac running iTunes*
And elsewhere on the Homeplug network, I have:
H*omeplug power network -> Airport Express [set up as wireless access point]*.
If I connect the Express to the iTunes machine directly - leaving the wireless access details the same - it all works fine. If I move the Airport Express and reconnect over the Homeplug network, the Remote fails to 'see' the library, although I can still send music over the network (using the iTunes interface on the iMac) to the remote speakers.
My network uses the router as a DHCP (range 192.168.0.x mask 255.255.255.0), Airport Express is connected to Homeplug ethernet with a static IP (in the same range) and provides wireless access (unsecured for now while i get this working). The iMac has a static IP (in the same range). If I swap the iMac for a PC (XP - using DHCP from the router for IP), I get the same result. If I use an iPhone network application to view the network (connected by the wifi access point on the AX) then I can see all the machines on my network as I would expect.
To reiterate, if I cable this network directly (either AX->iMac or AX->hub->iMac) then it works. As soon as I go AX->Homeplug power network->iMac then the Remote app loses sight of the library.
I wouldn't expect any firewall on the wired->wireless networks on my router (a Sky branded Netgear 934g). I also didn't think that the Homeplugs would block.
So does anyone have any ideas why the Remote application loses sight of my iTunes library when connecting via Airport Express cabled into a Homeplug ethernet network ?
Thanks for any help because I miss my music
cheers,
Tim

Hello,
This is the same for me. Impossible to find a solution after.

WAP4410N wireless traffic locks up even when running latest firmware update

I maintain multiple buildings, and each building has anywhere between 1 and 4 Cisco/Linksys WAP4410N access points. The problem is that at random intervals, the access points just stop sending and receiving wireless traffic. Every day or two, I have to log into every single access point (either via HTTPS or SSH) and reboot them in order for them to start working again.
In short, here are the config details:
They are all version 2 hardware (either WAP4410N-A V02 or WAP4410N-E V02).
They are running IPv4 (IPv6 is disabled) and get static IP addresses via DHCP.
When there are WAPs with overlapping signals, each WAP is on a different non-overlapping channel (1, 6, or 11).
Each WAP has two SSIDs (with spaces in their names). One is secured with WPA2. The other is unsecured.
There are two VLANs on the Ethernet interface. Each of the two SSIDs are assigned to a separate VLAN.
There is a DHCP server on the network, so the WAPs do not actually assign IP addresses to clients.
All of the WAPs are running on PoE switches. However, some are gigabit and some are 10/100 switches. Brands vary (Dell and Linksys) and models vary.
Cisco finally recognized this issue as:
CSCtx62203—In certain environments and traffic model, the WAP4410N may lockup after some undetermined time. Workaround: Reboot the device.
As such, the workaround didn’t really offer anything new. Rebooting every WAP ends up being a very time consuming process. It’s awful. And since you have no control over when this issue surfaces and can’t put any safeguards in place, I get calls about it at various points of the day almost every day.
Supposedly the most recent firmware update (2.0.6.1) claimed to fix the issue, but it only seemed to make it worse. So now instead of a WAP locking up every day or two, it locks up anywhere between every 15 minutes to 4 hours when in use.
The firmware was updated and the following issue was fixed in firmware version 2.0.6.1: CSCtx62203—In certain environments and traffic model, the WAP4410N may lockup after some undetermined time. (A protection mechanism was added to guard against sporadic problems with client association that could occur after six to 24 hours.)
As for troubleshooting, there are no error packets. On access points running firmware 2.0.6.1, these messages appear:
Feb 7 13:42:27 Syslogd start up

These log messages appear on both WAP4410N-A V02 and WAP4410N-E V02 devices.
I noticed that when the “beacon stuck” message appears, wireless traffic locked up 10-15 minutes prior to the message’s appearance in the log, and the SSID drops for 4-6 minutes after the message appears.
Is there anything that can be done to address the issue?

1) LAN port speed doesn't appear to have any effect
2) Forcing a connection type doesn't seem to have any effect. This is also rather impractical.
3) I don't have that option (though there is a TKIP/AES mixed option). Either way, I'd rather not have to resort to using a weaker encryption method.
4) No effect.
I did manage to find some information about the error message (older versions of firmware didn't even offer that clue).
http://www.dd-wrt.com/wiki/index.php/Advanced_wireless_settings#Beacon_Interval
I ended up increasing the beacon interval from 100ms to 500ms under Wireless > Advanced Settings.
The wifi analyzer app on android seems to keep dropping the SSID when the beacon interval is set that high, so I might have to adjust it to find a good balance.
However, while it was set to 500ms, none of the access points went down for two days.
[edit]: I reduced the beacon interval incrementally down to 300ms. It started locking up at 250ms.

General question on SQL Server 2000 to Oracle 10g

Hello all,
I just have a general question on migration from SQL Server 2000 to Oracle 10g using SQL Developer.
How does it migrate Users with proper privileges from SQL Server to Oracle? Follow the interface steps? Or should the users be created on destination Oracle side?
Thank you.

Hi,
It depends which type of migration you are making.
For a 'Standard' migration when you migrate data a 'create user' statement is created as part of the migration and you will see this in the generated code.
If you are using the 'Quick' migration option then you need to create the Oracle user or use an existing user to receive the data.
Your best option is to review the documentation available from -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
or directly from -
http://download.oracle.com/docs/cd/E12151_01/index.htm
and then get back with specific questions if this does not give you the information you need.
Review the chapter -

Report Builder Question - OA AR Aging - and a general question

I'm sure this is the wrong forum for this question, but I thought there might be someone here who might be using Oracle Applications and Report Builder who'd be kind enough to help me out.
We've recently implemented Oracle Applications 11.5.10 and I have to use report builder to change the Accounts Receiveable Aging (7 bucket) to a 5 bucket report. I've already made some changes to the seeded "ARXAGMW.rdf" report, but I'm not a big Oracle Reports guy. I've stumbled through making some changes in various other reports. But this one is just plain nasty! :)
I was thinking that I could simply add buckets 6 & 7 to bucket 5, then just hide or delete the 6 & 7 buckets. But I'm not sure where to even start. Any help with this would GUARANTEE a Christmas or other holiday card this year! :)
I really want to keep this simple as possible, so any help would be very....helpful. :)
Oh, my general question is: Are there any resouces/books for Oracle Reports (Report Builder)? I feel so lost trying to modify existing reports, let alone creating new ones.
Thanks again!

General question about iTunes Match and multiple libraries

Hello to everyone,
I have a general question about the iTunes Match service, which is available since yesterday in my country (Italy). Currently my library situation is the following:
Computer A (desktop, Windows 7): "big" iTunes library (about 20 GB), at the moment not associated with my Apple ID
Computer B (MacBook Air 2011): "small" iTunes library (about 5 GB), associated with my Apple ID
At the moment, both my iOS devices (iPhone 4 and iPad 2) are synchronized with the smaller library on the MacBook Air.
Question is as follows: should I subscribe to iTunes Match, would it be possible to upload the "big" library (provided I associate it with my Apple ID) to iCloud while keeping my devices synchronized with the "small" one?
Ideally, at the end of the day, the situation should be the following: both iOS devices with music from the small library + possibility of downloading songs from iCloud (coming from the big one). Is this possible?
Maybe the question sounds stupid, but I want to be sure about this before paying for the service.
Thanks a lot.

Yes, you could also associate your larger library with iTunes match if you associated your Apple ID with it. However any purchases in the library made from another Apple ID will not be matched with iTunes much.
If both libraries are part of iTunes match, then all your devices will see all of the content from both libraries, which content you choose to have on those devices and which you have accessible via iTunes match is entirely up to you.

Multipmultiple Airport Extreme Base Stations: WDS Or "Extend Wireless Network" To Have Wired -- Wireless Bridge?

Hello there!
I've been looking for this info, but have as yet been unable to find it. Here's my scenario:
I have two Airport Extreme Base Stations (both are dual band) and 3 airport expresses. The main internet connection in my house is in one room, where I have an AEBS as the main wireless router. In another room, I have a bunch of ethernet-only devices. I'd like to use the 2nd AEBS in this room, plug the ethernet devices into it and have the 2nd AEBS act as a wired <--> wireless bridge (connected to the same wireless network as the 1st AEBS). I've attempted this via "extend a wireless network," but the ethernet devices don't get past the AEBS they're plugged into. Should I instead be implementing WDS?
I mention the airport expresses as I'd like to have airtunes & wireless signal in other areas, but would like to keep the set-up as simple as possible (i.e., not config the AXes for WDS unless it's required).
Thanks in advance for any help!

Unlike the 802.11n AirPort Express Base Station (AXn), the 802.11n AirPort Extreme Base Station (AEBSn) cannot be configured as a wireless Ethernet bridge.
However, there are at least two ways to configure it to provide wired clients access:
Connect the second AEBSn back to the first by Ethernet; reconfigure the second AEBSn as a bridge and disable its wireless radios, or
Reconfigure both AEBSns into an extended wireless network. For 802.11n AirPorts, this would be called a dynamic WDS. The AEBSn, connected to the Internet would be the "main" base station and it would only require that you enable the "Allow this network to be extended" option in the AirPort Utility. The extending AEBSn would need to be configured with the option, Wireless Mode = Extend a wireless network, enabled.
In both configurations, the second AEBSn's Ethernet ports would be enabled for wired clients.

General Question on Proxies

Hi,
I have few general questions....
How to decide which proxy to be used: Java or ABAP?
What are the deciding factors?
Which one is better when it comes to performance?

Where to direct a general questions about foreign films subtitles?

I recently purchased a foreign film "Break Ke Badd" from the iTunes store. Although, it didn't specify that it had English subtitles, I assumed it did. After the full download, I tried to watch it and there weren't any English subs. I contacted iTunes and they more than happy to refund the money back to my account. Now after a few weeks, the iTunes store DOES list Eng subs for this film. I don't want to purchase it again and have to contact iTunes for another refund...Therefore my question is, is there a general question contact one could use to find an answer to my question. Basically, to verify that this movie, indeed has English subs before I re-purchase.
Any info is appreciated!

Yes I know as the [https://support.mozilla.org/en-US/questions/ Questions] section is more for desktop Firefox support and the place I linked to is for "Firefox OS" support in English where some who are involved with it do post in it occasionally.
I would have moved that [https://support.mozilla.org/en-US/questions/962783 thread] to the "Firefox OS" English section, however I cannot as the [https://support.mozilla.org//questions/ Questions] and [https://support.mozilla.org/forums Contributor Forums] are not the same.
