Yesterday my wired connection worked, today it does not.

As I said in the title, it stopped connecting successfully from this morning. Usually it got connected at boot, via systemd and [email protected]
Now not only it doesn't do that, but even running dhcpcd manually won't work.
If I try systemctl status [email protected] I can see that it failed. First the reason was that it didn't get an IPV6 address, now it says "Network is unreachable". This is so weird. At first I thought the reason was that probably the router does not support IPV6, so I added ipv6.conf.all_disable_ipv6 = 1 (something like this, I don't remember exaclty) to /etc/systemd.conf.
Now nothing works...
Please help if you got any suggestions! Thanks in advance,
rubik

I recovered my back up via a wired connection. now Time Machine does not recognise older back ups wirelessly and wants to do a first back up

I recovered a back up from my time machine via a wired connection after getting the 'white screen of death'. Now Time Machine does not recognise any back ups on the time machine when connected wirelessly and wants to do a first back up of the whole machine. How do I get my mac to recognise these older back ups? It connects to the wifi network the time machine creates fine, with the same name and password.

I recommend the following.
1. Reset the TC to factory.
Universal Factory Reset.. any model TC or AE.
Unplug your TC/AE from power or turn off at the power point.
Hold in reset. and power the TC/AE back on.. all without releasing reset and keep holding in for about 10sec. (this is often difficult without a 2nd person or a 3rd arm).
Release it when the status light flashes rapidly. If it doesn’t flash rapidly you have missed it and try again.
Note..
Be Gentle! Feel the switch click on. It has a positive feel.. add no more pressure after that.
TC/AE will reboot after a couple of minutes with default factory settings and will wipe out previous configurations of the router.
No files are deleted on the hard disk in a TC.. No reset of the TC deletes files.. to do that you use erase from the airport utility.
2. Rename the TC to SMB standard.
That means short names.. 2-20 characters but less than 10 is excellent. eg TCGenx (use number for x that is actual generation of the TC)
No spaces.
Pure alphanumeric. No apostrophe.
3. Ensure IPv6 is set to link-local..
Do the same thing for ethernet if that is used.
4. Manually mount the TC disk in Finder.
Use Go in the top menu.. connect to server.
Type in
AFP://TCname.local (where TCname is your new short name for the TC and local is default domain .. it helps using the domain I found).
You will then find the computer either can or cannot find the network resource.. if it fails something else is wrong with the actual network and you will need to fix that.
It will request the password if it is found.. password is public by default unless you changed it.. type in the password and check to keep it in your keychain.
5. Delete current TM setup and redo it with the newly named TC.
See A4 here. http://pondini.org/TM/Troubleshooting.html
If your backups cannot be found, try B6 again, now that you actually know that the disk has been properly discovered.

Yesterday airtunes worked, today it does not

I'm using a MacBook (the least expensive one) and an Airport Express. Wireless internet is working fine, but when I select the Airtunes speakers in iTunes, I get a pop up that reads: 'Connecting to Joshua Skaja's Airport.' Which would be great if in fact it was able to connect with my airport, but it times out. I used it yesterday for the first time and it worked great. I was thrilled to hear music on something other than the diminutive speakers on the MacBook. When I got to work & played music I got the pop up saying "can't find JS's airport, use computer speakers?" or something to that effect. No big deal. But when I got home, I couldn't get the airtunes to work!
Today I updated all my software (OS X, iTunes, others) in the hopes that that would fix it, but still I have nothing. Am I missing something obvious?

Connection works but program does not continue in the code ?

Hello,
I have a client, a server and a data class implementing Serializable interface.
Both classes communicate via sockets.
Between the sockets I transfer objects from the type of the data class.
The client and the server are running each in a Thread.
First the server is started then pressing a certain button in the GUI the client is started.
1. Why is the code in the clients Thread never going beyond this code line: System.out.println("test"); ???
2. Why is the file satz.dat not written ?
This is the part code of all 3 classes which is making me trouble:
Client code:
public class ClientThread extends Thread
       ClientThread()
       public void run()
            try
                 InetAddress ip = InetAddress.getByName("localhost");
                 Socket socket = new Socket(ip , ServerThread.PORT);
                 System.out.println("test");
                 ObjectInputStream incomingObject = new ObjectInputStream(socket.getInputStream());
                 ObjectOutputStream outgoingObject = new ObjectOutputStream(socket.getOutputStream());
                  outgoingObject.writeObject(serializeObjekt(meineBuchdaten)); // serialize the object "meineBuchdaten"
                  incomingObject.close();
                  outgoingObject.close();
                  socket.close();
            catch (Exception e)
                  e.printStackTrace();
Method to serialize the string data of the data class called Buchdaten class:
public Object serializeObjekt(Object objekt) throws IOException
          ObjectOutputStream oos = new ObjectOutputStream(new BufferedOutputStream(new FileOutputStream("d:/satz.dat")));
         oos.writeObject(objekt);
         oos.flush();
         oos.close();
         return oos;

                 ObjectOutputStream outgoingObject = new ObjectOutputStream(myClientSocket.getOutputStream());
                    Buchdaten bd = (Buchdaten) incomingObject.readObject();
                    System.out.println("This should be the deserialized data: " + bd);
                    myClientSocket.close();
          catch(Exception ex)
               System.out.println(ex.getMessage());

Oh, and by the way, is there a reason you aren't just using normal java RMI?
Edited by: jtahlborn on Feb 1, 2008 9:34 PMOh, and by the way, is there a reason you aren't just using normal java RMI?
yes for now i have to do it this way. The app must only run on my home pc but later i have to do it with RMI, but first it must work with sockets and streams etc stupd i know... ;-)
sabre150: quote:"As with all two way communication, one thread should be used for writing and another for reading. This ways the blocking nature of the streams works for and not against."
0: Does that mean i have to open 4 threads ? 2 threads for the client class and 2 threads for the server class? each one has an ObjectInput/Output - stream right?
For now i have only opened the outputstream on client side and the inputstream on server side to see wether it works at all. Furthermore my object is now serialized to the satz.dat file and it works.
1. Is there a way to serialize my data "meineBuchdaten" on-the-fly without writing it into a file on harddisk?
2. I want to print out the deserialized data but it doesnt work i get no output using the system.out.println method?
3. After this output: Connection done - handshake Socket[addr=/127.0.0.1,port=3139,localport=10001] I get this output: null
why null? from where does this null come?
Edit: ok my debugger work now again i reinstalled eclipse... debugging the cast into "meineBuchdaten" is the problem because right after this the debugger jumps into an exception this one
catch(Exception ex)
               System.out.println(ex.getMessage());
          }Edit: I have changed again the code a bit only this:
// Output of the deserialized data for test purposes
System.out.println("This should be the deserialized data: Autor: " + bd.getAutor());
its accessing the autor attribute variable of the bd object in a proper way but still the bd object is null i guess the problem is my serialized data on the client side is not transported what do i wrong can someone pls help me please ?
changed code:
client class:
public class ClientThread extends Thread

Wired internet works fine, wifi does not work at all...

I can't connect to my home wi-fi network (connection is fine when using ethernet). I've confirmed the password to my network is correct, and I've tried to reconfigure the airport connection to no avail. I've tried DHCP, DHCP with manual address, and manually--even tried turning DHCP off. When I tried just DHCP, I also tried to renew the DHCP lease, which didn't help. I'm stymied, and starting to wonder about the wireless network card.
I can connect fine with my laptop (MacBook Pro). The wireless router is about 3 feet from my desktop computer, so I'm pretty sure there are no reception issues.
Do you have any ideas for me?

Hi BDA,
I turned off the security in the router, and Airport worked just fine. So that's good, I guess the Airport card is healthy.
Then I turned the security back on to WPA in the router and can't log in. I rebooted (the Mac) and tried to turn on Airport, but the prompt which asks for a password will not accept the password. So I thought maybe it needed to be put back into the keychain (I am not very familiar with how the keychain works, it seems to be kind of automatic?). Anyway, I can't seem to enter the password into the keychain.
I did try WEP in the router, in case the airport card is so old it doesn't recognize WPA or WPA personal. That didn't do anything either.
Do you have any thoughts? I figured that turning off the security in the router is as good as rebooting as Ralph suggested.
Thanks for your time.

I get wireless connection but my internet does not work on my ipad 2

I get wireless connection but my internet does not work on my ipad 2

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Apple TV won't connect to iTunes and does not show up in my devices list in iTunes.

My older model Apple TV won't connect to iTunes and does not show up in my devices list in iTunes. I have two Apple TVs in my house and I can't imagine that this is part of the problem but I mention it just in case. My other Apple TV is brand new and it connects to iTunes just fine. I've tried most of the "fixes" and one says to Force Sync but I can't since Apple TV isn't in my device list. Another "Fix" said to Navigate the Apple TV to Settings --> Downloads --> Check for Downloads, but when I tried that there was no option for "Downloads" under the Settings Heading. I'm at a loss. Please help. Could this be an issue with too many authorized devices? We have three iPads, two iPhones, laptop, desktop, two Apple TVs, and an iPod and most of them are syncing the same music playlists and whatnot... have I run out of rope?

hi, just posting to everyone in general..its not you, or your apple tv, it is itunes.
ok, ive had the exact same issues for weeks now, as with everyone i had done the lastest upgrade and no longer could see/sync my gen 1 appleTV.........so, i removed the upgrade and went back to the prev version, even though it was showing in my prefs under appleTV, it still wouldnt show in the side panel under devices....i gave up.
This week i was determined to get it to work! So i started from scratch, totally removed itunes and started back with version 9 and upgrade each version from there, i had no luck, ic clicked find appleTvs but it wouldnt....however i just d/l version 9.2.0.61 and BINGO!. No sooner has it opened and up popped the side panel devices list, showing my appleTV..all ready to be synced etc. I immediately panicked of course haha..and set it all up and its working perfectly.
...Only catch now is that this older version will not be compatiable with my iphone, which i do keep music on...seems we cant win. grrrrrrrrrrrrrrrr this will be the same for all the latest apple products.
Apple needs to allow more than one version of itunes per pc OR perhaps they could get their act together and include all of the millions of APPLETV GEN1 owners in there latest upgrading..after all, THEY made the product and THEY do sell the movies/tv shows, perhaps they could stop making all the upgrade all about the music only!......on which i might add why not incluse movies/tv shows in icloud! yet another upgrade that should be included in the APPLETV GERNERATION 1!..yes we do still exist!
at the very least, im happy ive managed to get all my movies etc onto the apple tv, where ill keep them and from now on d/l directly onto my apple tv. I usually d/l to my laptop and then send them to the appletv but while trying to get all this sorted i did a test, i d/l a movie using my appletv hoping it would somehow let itunes "find" it and getting it to show up in my device list, but it didnt work, however it did sync/send the movie to itunes.. so at least i could save a back up copy.
good luck trying, as i said this has been weeks and this is the only solution ive found so far....and going through these forums its obviouse its itunes thats the issue, NOT Our apple tvs.

I would like to use my work exchange email on my macbook pro. But I cannot insult it. I have not problem as on my iPhone or iPad. My work IT person does not know what is wrong.

I would like to use my work exchange email on my macbook pro. But I cannot install it. I have no problem my work email on my iPhone or iPad. My work IT person does not know what is wrong. Why I try to set up the email I get the message that it cannot connect to this server.

Try going into System Prefereces then Mail, Cintacts & Calendars then click on the Microsoft Exchange link on the right. Type in your email address and password and allow it to set it up automatically.
Make sure your Mac is updated to the newest version of Mail.
If that still fails then I suggest you switch email clients. I don't care for the built in mail program. IMHO it is very buggy.

Network connection was reset store does not connect

there was a change of dns server for my iTunes store and not go over the followingmessage: network connection was reset store does not connect, what can I do to fix it my pc is an xp professional.

Do you have Norton AntiVirus? It could be that Norton is blocking iTunes from working because it considers iTunes a virus. If you think this is the problem, only uninstall Norton if you have your account information or if you are willing to buy a different AntiVirus program.

Main speaker stopped working. Phone does not ring, sound only through earpiece/headphone. What to do?

main speaker stopped working. Phone does not ring, sound only through earpiece/headphone. What to do?

I spoke to the reseller today and they aggred to exchanged it. They didn't elaborate on the actual cause but thought that it had to be a hardware issue.
It could either be the issue that Euvix suggested or it could be as simple as the outer speaker is simply not working.
Anesi, did you use the phone before the upgrade? Looking at what you've written I take you didn't so I would go back and get it exchanged.
