Repeated Problems Accessing Secure Network - Which Pref Do I Delete?

More often than not, when I awaken my 20" iMac G5 from sleep or do a cold startup, it won't connect to my home network. It's an Airport Extreme closed network using WPA encryption. I'm running 10.4.6 on my G5. When this occurs, it tells me that none of my "trusted" networks can be located, do I want to logon to one of the other local networks in my area (there are a couple).
When I try to log on manually by selecting "Other" in the Airport menu bar dropdown menu, often it takes me 4-5 times to logon even though I know I'm entering the name, encryption level, and password correctly. The error I get is always "The selected network does not support this method of encryption" and gives me the option to try again. After a few repeats, I can get on.
I'm figuring that I have some corrupt preferences file or files somewhere. Do I delete them (if so, which ones?)? I've done both hard and soft resets, yet the problem has recurred.
Any suggestions for this annoying problem would be appreciated.
iMac G5, 20" Mac OS X (10.4.6)

On your Mac.......
Open System Preferences (gear icon on the dock)
Open Network
Click on WiFi on the left
Click Advanced at the lower right
Here you will see the connection order list for your Mac
Make sure that your preferred network is at the top of the list. If it is not, drag it there.
Click OK at the lower right of the window then click Apply and close the windows
Restart the Mac to see if it will connect to your preferred network now.

I am currently having problems accessing a network connection. I have reset my IPAD network connections and am still having a problem. I know that it is not my network because I can access the internet on my laptop computer.

I am having problems opening any email or apps on my IPAD 2. It says there is no network connection but I don't have any problems accessing the internet on my laptop.

In any event, if your OS X version is 10.7.x, download and install AirPort Utility 5.6 for Lion:
Lion: AirPort Utility 5.6.
If your OS X version is 10.5.x or 10.6.x, download and install AirPort Utility 5.5.3:
Leopard, Snow Leopard: AirPort Utility 5.5.3.
After you install the appropriate version of AirPort Utility, open it. The program will be located in your Utilities folder, which in turn is found in your Applications folder.
To open the Utilities folder, go to the Finder and select "Utilities" from the Go menu:
AirPort Utility 5.6 looks like this:
... but make sure you use the version of AirPort Utility you just downloaded.
Launch AirPort Utility and select your Time Capsule. Click Manual Setup, then the Guest Menu tab, then you can elect to disable the guest network, or to establish whatever security settings you want.
The window looks somewhat like this:
If your version of AirPort Utility does not look anything like that, you are probably not using the one you just downloaded. Find it and start over.
When you are finished configuring your Time Capsule, click Update and allow the Time Capsule to restart.

Safari and iTunes having problems accessing secure sites

I've been having problems with iTunes not being able to access the iTunes Store. I can browse the store but can not add anything to my shopping cart. I decided it was time to see if Safari was having problems with secure sites and sure enough I discovered that it can not access secure sites either. The only way I've been able to access secure sites is via Firefox.
A typical scenerio is that I can not log onto my Apple ID. As soon as I click on the "sign in ID" link I get a pop-up stating that a secure connection to store.apple.com can not be established.
So far I've tried clearing the Safari cache and deleting site keys from my stored key chains. Nothing helps.
I'm running Safari 1.3.1 and iTunes 4.9.

Can anyone help?

Need help configuring VPN - problems accessing the networks

Hi everyone, hope someone can help me out here.
I'm administering the network for our small company. We basically have two sets of machines - public ones with fixed net addresses (mail, web, dns servers, etc), and private ones behind a wireless router/nat.
Our main need here is to be able to VPN in to the public side, in particular, the mailserver, so that we can get around all the stupid things that get done to SMTP when we connect at the BedBug Inn ("Free wifi, administered by gibbons").
Secondarily, it would be nice to be able to connect to and browse some of the internal machines.
So here is what I did:
* Installed 10.4.10 Server on a machine with two ethernet interfaces, one that has a public IP address, the other connects into the private network. When I'm actually at that machine, things work fine - I can browse the private network shares, connect to the net, etc.
* Configured VPN. I have no problems getting a VPN connection, both sides are happy. The VPN assigns incoming clients IP addresses in the private network IP range, but outside those assigned by the wireless router's NAT.
* Added 192.168.2.1/255 (the private network) and 12.17.29.193/224 (the public network) to the Network Routing Definition box under VPN/Settings/Client Information.
However, here's where it all falls down. Once the VPN is established, I can't connect to any of the public machines, and the only private-side device that seems to respond is the Wireless/NAT box (A Belkin N1). So the only thing I can do is administer the Belkin remotely, which, while nice, is not exactly what I had in mind.
Doing a traceroute while VPN is active to my mailserver shows the first hop direct to the VPN machine, then off into * * * heaven (though I have no idea if traceroute works over VPN!).
One curious note: when I change the order of the Network Routing Definitions so that the public network comes first, and the private one second, I can't contact the Belkin box.
Any advice, oh wise and powerful masters of technology?
Various, but the server is running on a G4 Mac OS X (10.4.10)

I said:
"let's assume I VPN to the wireless box"
You replied:
"That's not correct as it is not the device running the VPN endpoint - in this case. "
But wouldn't I have to (on the VPN client) specify the public IP of the wireless box in order connect (because the packets are forwarded) to the actual OS X box running the VPN? Otherwise, it can't see it.
Part of the problem I have is that I can't dedicate a whole machine to VPN. The OS X machine running VPN is also running DNS, and will eventually run our mailserver and perhaps FTP, web, etc, as I slowly migrate stuff to it.
So this machine has to have a public IP address. It cannot be hidden behind the wireless NAT. And it seems to me that this is the crux of the problem. What I think you are telling me is that if the VPN machine was entirely hidden behind the wireless NAT, and had no direct public (WAN) interface, then since all the packets destined for the outside world (including my public servers)would have to go through the NAT, and all would be OK.
If so, then it seems to me that the best solution is to use something like OpenVPN on another OS X (not OS X Server, since I only have one of those) machine in the private network. Since the incoming VPN traffic will be Mac only, it shouldn't be an issue, L2TP-only is fine.
"Otherwise you have to run NAT and the firewall in the VPN server too and use private IPs for VPN clients - or use "only" it (remove the other NAT box and put it on the LAN only). Using only one device for NAT/gw means less configuration."
It is entirely unclear to me, in my setup, what effect turning on NAT on the VPN box (or perhaps, just IP forwarding) would have -- and if I do turn on NAT, would I still have the VPN assign IP's to clients in the internal private network's range, or would I use a different range (ie: private is 192.168.237.xxx, VPN assigns 192.168.239.xxx) and expect the NAT to handle the conversion?
I'm a bit leery of just trying it and seeing what happens because it if mucks things up so badly that the server becomes unreachable (via server admin), I'll have to schlep down to the office to fix it.
"Other things to consider is "bottlenecks" between your LAN and WAN."
Not a real issue. We have a small office, and a relatively small pipe to the internet. Most of the traffic from that pipe is from the public machines anyway. The traffic that goes through the wireless router is basically websurfing and hitting the mailserver.
I could, of course, use the VPN OS X machine as the NAT/DHCP server, and hang the wireless router off the internal network as a simple access point. But would that resolve all the VPN issues?
Once again, thanks for your helpful and prompt replies.

Problem accessing Windows network - permission checking is inconsistent

I am in the process of making the move at my workplace from a Windows/Solaris environment to an exclusively-Solaris workstation environment. I have wanted to do this for a while but now that Evolution is bundled in with Solaris 10 I have finally embarked down this path.
One of things that I need to be able to do is access Windows shares on our corporate network. I am having a few issues with this using the Java Desktop system in Solaris 10. Here is a quick view of the windows network hierarchy.
Windows Network -> Sub-network -> List of machines ->
List of folders on a given machine -> List of sub-folders within a given folder and so on ....
Here is what I am trying to do.
1) Double Click 'Network Places' from the desktop.
2) When the window 'File Browser: Network Places' opens, it appears that my Solaris workstation has automatically detected the presence of a Windows network. Very slick!
3) Double click on the 'Windows Network (SMB)' icon.
4) A list of sub-networks appear. Occasionally this list is not 100% complete. ie. there are 5 sub-networks but only 2 will appear on occasion.
5) Double click the smaller network that I wish to access. The various machines within this network appear as a list of hostnames.
6) Double click on the machine that I wish to access and a list of folders on this machine appear.
7) Double click on the folder that I wish to access and a list of subfolders is presented. When I try to naviagte deeper an 'Authentication Required' window appears. I enter my username, password and domain. I also check the 'Remember password for this session' and 'Save password in keyring' options.
8) I am prompted with a 'Create Default Keyring' window asking me for a password to associate with the default keyring. I enter the same password that I entered in Step 7.
9) A list of subfolders appears. This is great. But when I attempt to navigate any deeper ... I cannot. A dialog pops up saying "The folder contents could not be displayed" with a message stating "You do not have permissions necessary to view the contents of the "foldername".
At this point, the file broswer gets in to a funny state. I try to hit the 'up' arrow to return to the folder which I could previously access but I am now greeted with a dialog claiming that I do not have permissions to access this folder. I cannot access anything past the first folder level on a given machine even though I could just a minute ago. This "funniness" clears up after some length of time. ie. if I come back in an hour, I can once again reach part 1 of step 9 without being greeted with permission errors.
Are there any SAMBA config options that I need to tweak or add to my smb.conf file to make :
1) the listing of Windows networks be more consistent
2) the permission checking to be more consistent and stable
Or does the issue lie on the Windows side of things.
Thanks in advance for any help,
Tim

Thought I would update this one myself in case anyone else was having similar problems with a baseline Sol10 install. I suspected the problem was with Samba or the GNOME Keyring Manager. I downloaded Sun's new Update Connection tool to stay on top of patches. (http://www.sun.com/download/products.xml?id=42e02045) I installed a slew of GNOME and underlying OS patches and things are working now. Pays to stay up to date. ;)

Problems accessing secure zones in admin panel from Chrome

Is anyone else having this issue? I have tried everything I know and every time I try to access and individual secure zone in chrome it just tries loading and never get anywhere (like after hours) but works fine on safari.
I contacted support but they seem to think it is a cache issue with me (but I don't have cache enabled and have cleared my entire history). urg.

I have the opposite view. I would expect people in the industry to frown on AdBlocking since we often build projects for clients that rely on advertising to survive so you can appreciate the negative effect AdBlock has on client's revenue. I don't know how you're pumping money into Facebook besides buying ads which you are then blocking. If anything, you are directly removing money from the pockets of the owners of these free sites which provide a valuable free service to you and yours.
And, you're right. I'm over it.

HT204088 anyone have any issues accessing security in sys pref? Mountain Lion

Does Anyone else have an issues accessing the Security/Password in System Preferences of the Mountain Lion OS. I have just upgraded this morning and got a message about not being able to access a site. It appears Moutain Lion has changed the security of accessing sites and need to be adjusted ot suit your needs. The problem is I can't access it. The Security icon is the only one of the icons in the system preference that hangs and I am forced to quit.
Any one else have this issue?

I'm not sure this will help. There is supposed to be a "Security and Privacy" preference pane in System Preferences. But on my MacBook Pro, there is no such pane visible. However, if I do a search in System Preferences for "Security and Privacy", the preferences open. So it's "there" but not visible. I don't know why.
However, if you try this and manage to get into Security and Privacy via searching in System Preferences, you might be able to do what you want.

Problem after securing network

I secured my network and now i can't use my network on my work laptop.
According to my deskside support i need to figure out my SSID. How do i find my encryption type? Where can i find my password or network key?

Hello APaq17. Welcome to the Apple Discussions!
According to my deskside support i need to figure out my SSID.
The SSID is the same as the wireless Network Name. By default, your AirPort Express Base Station (AX) will broadcast a wireless network with a Network Name of "Apple Network NNNNNN" unless you changed it.
How do i find my encryption type?
By default, the AX's wireless network would be unencrypted. You enable wireless encryption by using the AirPort Utility. Depending on the model of your AX, it should be capable of providing the following security types: WEP, WPA, & WPA2.
(ref: AirPort Utility > Select the AX > Manual Setup > AirPort > Wireless > Wireless Security)
Where can i find my password or network key?
Again this would be something you would have created when enabling wireless encryption.

Problems accessing home network via FTP

I get a -50 error when I try to FTP thru my company's wired Ethernet network to my home network via the "Connect to Server" command in the Finder.
However, I can connect with my home network using FileZilla thru the same (wired) network.
And I can connect to my homework via my company's wireless network from the Finder.
Any ideas what might be blocking me from FTP'ing to my home network via the Finder and thru the wired network, and how to resolve?

At least a partial answer.
If I use the command FTP://username@IP Address, I'm able to connect. But I don't have to use my username with wireless.

Help attempting connect to network which requires Cisco Clean Access Java

Wondering if someone could help me out. Attempting to access work network which requires Cisco Clean access Java applet. It gives me a link to Java. Question is does the itouch support java plug ins? Any thoughts gratefully appreciated.

I ran into the same issue on my university campus. This is what I learned. Apparently, iPod Touch has wi-fi 802.11 and does not support 802.1x authentication method, which some universities and workplaces use. I do not know if there is (or will be) a solution. Hope that helps.

10.4.10 connectivity with secure network, 2wire router

It's obvious in the forums that the 10.4.10 update is causing some wireless connectivity problems in secure networks like my SBC DSL connection that uses a 2Wire modem/router combo. Kernel panic every 5 minutes or so with multi-lingual message prompting for hard restart by pushing the power button displayed enormously on-screen about the size of a can lid. Pretty outrageous I'd say!
So I decided to go with a clean install of OS X and decline upgrade to 10.4.10 and now it seems to be working fine again.
My question: Has mac released any kind of statement regarding this because I am yet to witness one. Should we expect mac to make the appropriate changes or should we seek our ISPs for support?

would it just be possible to use my 2wire as a regular DSL modem with some other router? Would that help? Should I find a new ISP? Should I hope for an update from apple? It appears to only be affecting 2wire routers, or possibly other secure gateways...

Problem accessing an object in a VBox

Hi!
I have a problem accessing an object which is in a VBox.
I made an example so you can see my problem. I am trying to
access pnlChat.
If you load the swf you won't see the Alert because there is
something wrong (and I don't know what)
If you try to remove the <mx:VBox> tags that wrap the
pnlChat Panel, it will work.
Why can't I access this object when it is in a VBox?
Thanks

From the FAQ I'm compiling:
Q: I need to set a property or add an event listener on a
component
that is in a ViewStack/TabNavigator/Accordion. When the
component is not
the first child of the Navigator Container, I get a null
object error
(#1009). What causes this, and how can I fix it?
A: By default, the Navigator containers only create the
children of
each pane as that pane is viewed. The easy way to fix this is
to set the
creationPolicy on the Navigator to "all." However, this will
cause your
application to take longer to load. A better way to fix this
is to wait for
a later event, such as creationComplete on the component you
want to access,
or to use binding to "pull" the data into the component.
The way I handle it is to call invalidateProperties() on
change of the
ViewStack. I then override commitProperties() and call an
"initializer" for
each pane. In the body of each initializer function, I check
to see if the
selectedItem for the viewStack is the one my initalizer cares
about. If
not, I return from the function immediately. Inside that
initializer
function, I set properties and add listeners as appropriate.

Having problem accessing MacMini over network with PC's Windows 7

Hi all,
I have a Mac Mini with 10.6.x
Onec in a while, especially when restart Airport Extreme for upgrade or something else (both are connected with ethernet cable cat5e) ALL PC's on the network having problem accessing Mac Mini Server while All MACs are fine and can access all folders no problem. Usually takes about 3-4 min for PC to connect to server. Then once it is connected (it loads all folder and files in that current window on the PC) i can go from folder to folder with no delays. However if i close the window with all folders then again i have to wait for around 3 min. to load everything all over again. AFP and SMB are ON. Today i made an experiment and turned SMB off and the problem still excist with the difference that after 3-4 min delay no folders were shown.
It seems that the PCs have hard time establishing connection with the server which is weird that Macs don't have that problem. It must be something with the setting of Mac MIni. Other wise i have no problem accessing Internet so the routher is working fine. DHCP is ON on the AP Extreme.
I came across as i was searching for this issue and it seems that authentication - Golden triangle or whatever is called - might be the issue in the whole mess. Do you guys think that this might be the case ?
The only way i have found out to help is to restart the Router and Server and that usually fix the problem .
Could you please help me figure what is going on there?
Here is the original thread: https://discussions.apple.com/thread/3867559?tstart=0 ( i think i posted in the wrong forum )

The specified changeip -checkhostname command does not make changes to your configuration.
To research the command (and that's entirely your perogative), please use Google or Bing to search for previous discussions and details, or review the provided man page documentation for the command. (Launch Terminal.app (folder Applications > Utilities) and issue the command man changeip. You'll see something like this:
$ man changeip
changeip(8)               BSD System Manager's Manual              changeip(8)
NAME
     changeip -- Change service configuration files with hard-coded IP addresses
SYNOPSIS
     changeip [-v] [-d path] old-ip new-ip [old-hostname new-hostname]
     changeip -checkhostname
     changeip -h
DESCRIPTION
     changeip is used to manually update configuration records when a server's IP address or hostname changed in a way that affected services were unable to properly process, for example when the server is behind a NAT device and the WAN identity changed. ...
Given your response and your concern, consider creating a backup of your disk. Shut down, boot the installation DVD, and use Disk Utility (from the Utilities menu) in the second screen of the installation process to copy your disk contents to an external storage device. (Time Machine isn't as good at getting a backup of a server as is a clean backup created while shut down.) There are descriptions around that detail how to create this backup using Disk Utility.
There is no DNS server implemented in the Airport Extreme. The Airport Extreme forwards DNS requests to a DNS server elsewhere. Few gateway devices contain DNS servers; that these devices request a DNS address tends to be confusing, too. That address is solicited from the user for use in the DHCP server that many of the available gateway devices provide.
There is no need for a DNS forwarder, particularly if your server is configured for your LAN. (Adding a forwarder adds another hop into the whole translation process. That configuration and that extra hop can be useful when the intermediate DNS server is providing specific, enhanced DNS-related functions, such as security monitoring and logging, or providing a "nanny filter" mechanism.)
If you are running DNS services on your LAN, then your Airport Extreme DHCP server should be configured to pass out the IP address of your DNS server.
It would appear that your local box has the default self-hosted DNS, and is not configured to serve LAN DNS (other than for itself). That's good. Accordingly, it'll likely be getting good DNS from itself, but will not be getting translations for other hosts on your network. That's not so good. When DNS responses are not available, you'll get DNS-level timeouts, and those are usually around 30 seconds each.
Check your server logs for messages related to the failed connections, and check the Windows file service logs for any errors being generated by the file service. The log information is most easily available from Console.app, which is a utility in Applications > Utilities folder, or from the Server Admin tool (Applications > Server folder) for DNS, and for the file server component.
The above is probably going to read like a wall of unfamiliar jargon, so please ignore this and my previous response here, and I'll leave it to somebody else to assist you here.

Cannot access my own secure network with G4 iBook

I set up a WPA secure network with a AirPort Extreme Base Station. No problem using it with my G4 iMac. However, when I try to access it with a second computer, a G4 iBook laptop, using the same WPA password I use to access it with my iMac, I get an error message.
Using the Setup Assistant with the iBook gives me an "invalid password" message. I know it is the correct password. I set it up and I use it with the iMac!
When the network is unsecured (no password needed) the iBook can access it, no problem.
Please tell me what I need to do to be able to access my own secure network with my iBook. TIA!

The only thing I can think of is the firmware for the AirPort card in the iBook, which is version 9.52. I could not find anywhere in Apple's website how to upgrade this. Does anybody know how to upgrade this firmware?
If there is any firmware update to the card it is done automagically whenever the corresponding AirPort software update is applied. There is no user notification and no way for the user to make updates diretly.

Access a file which is in local network via jsp

i try to access some files from a system in the network.
i couldn't make it through jsp and servlet
im using tomcat webserver.
but in core java it works finely.
the below r the example code...
core java coding(It works)
class a
public static void main(String ar[])
String a="//software2/d$/Daily Shipment Backup";
      java.io.File f=new java.io.File(a);
      if(f.exists())   //whether the directory exists
System.out.println("Exists");
      else
System.out.println("Error");
}jsp coding

      if(f.exists())
out.println("Exists");
      else
out.println("Error");
%>
</html>

Tomcat (And other JSP/Servlet containers) have security restrictions which disallow you from accessing the local/remote file system. You will probably need to modify your security policy settings
I believe Tomcat stores this file in $CATALINA_HOME/conf/catalina.policy
