Down to basics - connecting to PC running XP

hi guys, im an absolute gimp when it comes to networking, so please be patient with me:
I have a macbook, running ARD 3. It is connected via wifi, to an Airport Base Station.
I want to connect to a PC, running Windows XP
I have installed RealVNC onto the PC, but now, when I open ARD, and select the PC form the scan list, it says "connecting" and stays like thus for hours.
What am I doing wrong?
Thanks
Tom

3283 is not necessary for connecting to a VNC server. Only 5900 is used (confirm that your VNC server on the PC is indeed using 5900 and not 5901 or some other port). Microsoft's Remote Desktop uses completely different ports.
How is the PC connecting to the network? Is it wireless to the Airport base station? Connected to the Ethernet port on the Airport? Or how?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Open ports slow down my internet connection. How to close them? What to do?

My MacBook Pro has massive problems with internet connectivity. At times the connection is blazingly fast, at times unbelievably slow.
I've spoken to my internet provider who was able to inform me that my computer opens up 500-700 ports which is probably what's slowing down the network connectivity. When I'm online with the MacBook Pro, the web gets unstable – also for other connected devices like iPad etc.
The web supporter asked me to run an anti-virus scan which I did – with no results. The problem persists. When my MacBook Pro is not online, there are approximately 15 ports open, when I log on the web that number increases to between 500 and 700.
Is this normal?
Can anyone tell me how to solve this issue?
How do I figure out which application opens these ports? (and how to close them?)
I tried logging into another user account on the computer and the problem seemed to disappear, indicating that it is caused by something run only on my user account.
Hope someone can help me..

Open ports don't slow down your computer. The tech support person you spoke to doesn't know what they are talking about.
Basically, when you are using a web browser, opening a page means that the browser needs to open a connection for each element in the page (e.g., it needs to grab each picture, CSS, and JavaScript file that the page requires). This could be a couple of dozen, or it could be hundreds (and there's no telling what Flash content on the page will do). The browser tries to mitigate things a bit using a cache (you might check to make sure the cache is turned on, but this is the default setting). However, this is how all browsers work and how the whole system is designed to operate. You cannot "close" any ports, and they don't linger open, they remain open only as long as data is being transferred. This is expected and appropriate behavior.
The most likely culprit is that you are receiving poor DNS service from your service provider. Every time the computer sees an address like 'http://www.google.com', it needs to send out a request to figure out what numerical address goes with the human-readable name. If the DNS service your system is assigned to use doesn't respond lightning-quick, your experience is going to be very sluggish.
You might want to add an external DNS service to your list of DNS providers. Go to System Preferences > Network, select the network you are using on the left (Ethernet or AirPort), and click the 'Advanced' button. Click on the 'DNS' tab, then press the '+' button under the left panel. I would add the OpenDNS.com DNS servers. Add the following DNS addresses:
{quote}
208.67.222.222
208.67.220.220
{quote}
Click the 'OK' button. And then the 'Apply' button to save the changes.
That will probably fix the problem. If it doesn't the next most likely issue is either network congestion (e.g., your ISP's network is just too busy; a very common thing for small ISPs and cable Internet service), or the remote site that you are trying to contact is simply not performing so well.

My MacBook Pro 13'' shuts down randomly while connected to the power cord.

Alright, so my Mac is shutting down while being connected to the power cord. Though, when I unplugged it, it runs just fine.
I've read up on the other random shut downs but they seem to be different in my case. I was only surfing youtuve on Firefox, granted I had a few other tabs open but they weren't doing anything that would run the computer hot, and it shut down out of no where. The battery was full and it was still connected to my power cable. The screen went blank and the computer was completely off. I noticed that the light on the plug in wasn't on and switch the outlet that the computer was plugged into and replugged it into my computer. The light came on and after about three or so times of pressing the power on button it came back to life. Though, it stayed on the start up, white apple page and just spun. After a while it looked as if it was about to go to my password page but it shut down after gently moving the computer. The power cable light went off once again. I unplugged it and replugged it into my computer but the light would not come back on. After just removing the cord and pushing the button a few times my computer came back to life and I logged in as normal except for the fact that after it came back on the date and time was reset and several applications needed permissions. It also randomly logged me out of my Facetime account as well.
All in all I was wondering if anyone else had a similar problem and know what's going on or if this is new. Could it be some kind of spark in the power cable from a broken wire that made my computer shut down or is it something attacking my computer?

Please make a Genius Appointment and take it in for service.

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.
Replacing or even suggesting replacing hardware without doing basic troubleshooting first is not very smart.
If basic troubleshooting does not resolve, take it to Apple for evaluation. There is no obligation to pay for anything, the evaluation is free.

ITunes shuts down when I connect my iPod 30gb

I desperately need help. Recently my computer crashes and I reformated it. So I had to reinstall iTunes. Ever since then iTunes shuts down when I connect my iPod 30gb. A windows error message appears saying iTunes has encountered a problem and needs to shut down. I am unable to update my iPod which drives me crazy. Somebody please help!
I browsed through some threads which have similar problems as I do, but I am unable to reply in any. It says: This topic has been archived - replies are not allowed.
There's this thread here about the problem I am facing but I doesn't seem to understand the solution to it.

Can somebody please help me?

A windows error message appears saying iTunes has encountered a problem and needs to shut down.
let's get a crash log from itunes, and send it to the Apple engineers for a look.
Typically, you'll need to configure Dr. Watson on your PC in order to generate crash logs. Windows start menu -> Run. Type in "cmd". Hit return. At the prompt in the command line window that comes up, type in
drwtsn32 -i
And hit return.
This will create crash logs in Documents And Settings\All Users\Application Data\Microsoft\Dr Watson\. There'll usually be a file in here called "drwtsn32.log"
prior to collecting the itunes crash log, delete any existing crash logs in there. (we want to make sure we send the correct crash log.)
Generate the crash, collect the crash log, and and send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- the version of Windows you are using (mention service packs)
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing

My Ipod nano 6Th sometimes shuts down when I connect the phones, sometimes it not shuts down, but the volume and standby buttons do not work.

My Ipod nano 6Th sometimes shuts down when I connect the phones, sometimes it not shuts down, but the volume and standby buttons do not work. If I not connect the phones everything works fine. But with the phones connected it goes crazy. I alredy reset, restore and nothing. If I reset and let the phones connect the up and down volumes buttons start to work. But the power/stand by button don´t. I need to disconect the phones to the power/stand by button starts to works. Anyone already have simmilar problem?

Time Machine backups slow down TC internet connection

I'm having a problem with my TC internet connection slowing down dramatically. When I connect my DSL modem directly to my Mini, it's fine. When I connect it to the TC there are big slow downs off and on. I'm wondering if the backups done by TM slow down the internet connection and the network as a whole.

Over ethernet no, it would have almost no effect.. over wireless yes.. it can have a big effect.
How big are the backups generally? These should only be incremental and relatively small.
Measure your actual speed of copying a file to the TC.. if you can put numbers to it, that will help. Use the Activity Monitor and see what is the average speed copying a file or when TM is backing up.
Any improvements to the wireless speed will reduce the time the backup runs and how much time your internet is slow. Wireless is highly range and signal dependent. You might find a network rearrangement where you use the TC close to the Mini can solve the issue.. especially if you can connect to it by ethernet.. and then wireless bridge if you need to.

Thanks for these replies! and fast!
I am not connected with a hub or a switch: it is a MODEM/ROUTER TrendNet TEW435BRM which goes well for DSL.
I cannot run dmesg for know... I will look in it later.
The computer is a new laptop (netbook type): Acer Aspire 1410 722G25n, Intel Celeron Mobile processor 723 (1.2 GHz, 800 MHz FSB, 1 Core, 64 Bits, 1M cache..., 10Watts max...), VGA: Intel GMA 4500MHD UP to 732 MB DVMT, 11.6" HD LED LCD
RAM: 2 GB memory, STORAGE: 250 GB HDD, WLAN: Acer Nplify 802.11b/g/Draft-N,
BATTERY: 6-cell 4400mAh Li-ion, SE: Windows Vista Home Premium OEM (EULA refuse by myself and deleted so not tested with it!).
$ lspci
01:00.0 Ethernet controller: Attansic Technology Corp. Device 1063 [1969:1063]
On the internet, some said that it is known as an Atheros AR8131 PCI-E Gigabit under Windows... and that the useful linux package is AR81Family-v1.0.0.10.tar.gz for them, but impossible to find on the internet (official site is down, the archive found elsewhere do not uncompress, etc...)
Linux is archlinux x86_64. The kernel driver in use is "atl1c" (on my ASUS eeepc beside, it is atl2 and runs well).
Ok, so:
- 1 read dmesg
- 2 try with another cable (the wire I used is old).
- 3 try with another kernel driver (have to find it)
- 4 send back the computer to be repaired!
Bye

Internet connectivity circle keeps running with all apps closed in IOS 7.1

Please help. Internet connectivity circle keeps running with all apps closed in IOS 7.1.
This only started to happen after the iOS 7.1 update !
Happened twice. Goes away after restarting the phone.

I can confirm all bugs detailed by 'Taxes', above, and would add that Calendar suffers from similar 'swipe' issues to Safari!
Doesn't anyone sit down and 'play' before release to check if these bugs have been exterminated?

How to get the values of drop downs, which are gonna create at run time.

As per my design requirement, I have to create drop downs in an ADF display table.
The no# of rows of the table are gonna decide the no# of the drop downs. User can select the values from drop downs. My issue is, how can I capture the selected values of those drop downs as those are gonna created run time.

Hi
ohh ,ok ,then as u said that u r storing twenty values ,thats y i aksed earlier ,are these form values part of tbale ,or as u said 20 values are there ,for these u r creating 20 form values ???.
My suggestion would be ,u do four calculation and put all your results in a hashmap ,and keep this hash map in to sesion ,using the following method
pageContext.putTransactionTransientValue("HashMapName",myHashMap);
and inside the PFR method when u want to display these values ,u can loop through your hashmap and can display these values.
like this
HasMap hm=pageContext.getTransactionTransientValue("HashMapName");
thanx

I own a 13-inch MacBook Pro and for the past day, my wifi on my laptop says I only have two bars of connection and is running very slow,but all of my other devices such as my iPhone and iPad are connecting perfectly to the wifi. How can I fix this? I have tried to shut my laptop off and let it rest and I have also re-started my wifi router three different times. Someone please help me with this problem so I can begin to use my laptop again as I take it to school and use it for class.
Thanks so much!

FCP, and all software on OSX, has a few different "preference" files (the extension is .plist), which store all your user settings. Each time you resize a window, change a setting, anything, this file is re-written. Kinda easy to see how they would become corrupt every now and then.
-Close FCP
-Navigate to User>Library>Preferences and delete com.apple.FinalCutPro.plist
-Navigate to User>Library>Preferences>Final Cut Pro User Data and delete Final Cut Pro 5.0 Prefs
-Empty your trash
Relaunch FCP and see if that worked.
Download FCP Rescue to make this process easier in the future. When you have FCP running really smooth, open FCP Rescue and create a backup of your preference files. If it starts acting wanky, just run FCP Rescue and Restore your backup preferences. Works really slick, and it's free.
EDIT: Or use the really simple explaination that X posted as I was typing.

What is the best way to connect a G4 running 9.2.2 or 10 to an new imac running lion?

What is the best way to connect a G4 running 9.2.2 or 10 to an new imac running lion?

It should be possible to network them easily.
Ethernet will be the most straightforward. There is no question that you can plug both Macs into a normal network and they can share files if you turn on File Sharing.
The iMac has a Gigabit Ethernet port, and if the G4 also has Gigabit Ethernet, that will be a very fast connection through a gigabit-capable Ethernet cable or router. Otherwise both can use the slower Ethernet speeds with no problem.
You can also network the two machines via a FireWire 800 or FireWire 400 cable if necessary, and use File Sharing that way too. Finally, you can put one Mac into FireWire Target Disk Mode, which turns it into a hard disk that the other Mac can see, but this is the least flexible since one machine goes out of service, and it's probably no faster than Gigabit Ethernet.

Jdbc connection blocks when run from jar

The following code establishes a connection EXCEPT when run from within a jar file:
String jdbcDriverName = "oracle.jdbc.driver.OracleDriver";
String dbConnectionURL = "jdbc:oracle:thin:@192.168.2.7:1521:PRISM";
String userName = "mdo";
String password = "mdpass";
// Load the JDBC driver and create a connection to the database
Class.forName( jdbcDriverName );
OracleDataSource dataSource = new OracleDataSource();
dataSource.setURL( dbConnectionURL );
dataSource.setUser( userName );
dataSource.setPassword( password );
connection = dataSource.getConnection();
When run from a jar file, the application does not execute beyond the line:
connection = dataSource.getConnection();
No exceptions are thrown, it just appears that getConnection never returns.
Do I need to do anything different to execute this code from within a jar file?
Thanks in advance,
Phil
<><

When building the JAR file, I inadvertently included files from two Oracle JDBC driver versions (1.2 and 1.4). I was building a single jar file with all files in it.
I am guessing same named files existed in both driver JARs and caused "confussion" when combined into the single JAR.
Still, I would have expected an exception to be thrown or a null connection to be returned instead if the thread just blocking.
Thanks for all replies,
Phil
