Intel Mac :: Why Does It Report A Duplicate IP Address
Mar 10, 2012
A few days ago, my wife told me that she was having some serious performance problems on her iMac, and showed me. While she was doing this, a window popped up announcing that there was a duplicate IP address for the 192.168.1.20 that we'd set her iMac to. I did a bit of digging, checking all our machines for that address, and trying to contact it to see if it would identify itself. Everything failed. None of our machines (that we know of) is using 192.168.1.20, and attempts to contact it via tools like ping, telnet, ssh, and various brousers all report "not responding".
I changed her address to 192.168.1.21, and the problem went away. But I'm still worried about the claim that 192.168.1.20 is in use. This seems to say that there's an unknown machines using it in our house.
So is there some way that her iMac or either of our Macbooks (or here iPad) can identify it, or at least contact it and give us some clues about what sort of beastie it might be?
We also have some linux systems, a Windows box, and a couple of smartphones with wifi, and tests from them have also failed, so I'll probably be asking on their lists, too.
My first suspect was the airport, but I verified that its DHCP server is giving out addresses in the .101 to .199 range that I set it to. Its config stuff doesn't show the .20 address anywhere that I can find.
(I did try setting one of the linux systems to use 192.168.1.20, and it didn't report any address conflicts. I don't know what this tells me. So I set it back to its original 192.168.1.42 address. ;-)
The contacts are unique, but each control group appears as many times as there are contacts in the group. Why is that? Can the contact group list be made unique?
I recently bought Scribblenauts Remix, which for some reason is not working on my iPad 2.
I tried to go to the support page of the developer to either get some help, or to get my money refunded... but the link doesn't lead to the proper place and I'm unable to figure out:
A) How to get support from the developer anyway;
B) How to report this to Apple, so I can get my money refunded somehow.
My sync is going wrong somewhere along the line and creating duplicate lists of some contacts to build up. I deleted them all yesterday afternoon and now have about 20 or so of some contacts. Some do not duplicate at all. I found this thread over at apple [URL] but as my mobile me account contains the duplicates as well cant get the workaround (deleting address book file) to work.
I have suddenly noticed duplicate contacts in my address book. I'm on the current version of Lion on a ne 27 imac and all updates are current.Don't really know why the duplicates started and haven't had this problem since the conversion from mobileme months ago.
I have many duplicate contacts in my Entourage address book (same name, different information in some instances). How do I merge those duplicates into just one contact?
After syncing with iCloud (three computers and a phone) suddenly I am seeing multiple entries for the same contact in the address book and multiple entries in the calendars for the same event. How to stop this and how to delete the multiple entries without having to manually delete each item? The new Address book does noit seem to have a list view that shows the entire address book 9only shows addresses with two or three alphabets. Is there a setting to prevent this from happening? The value of iCloud is lessened when these issues crop up and there seems to be no defined method to fix the problem. I see numerous entries on the Support Community boards with the same problem.
Info: iMac, Mac OS X (10.7.2), iMac Core Duo and MacBook Air Lion
My current address book has roughly 300 contacts. I have an old archived address that has roughly 200 contacts, but some contacts have extra information (ie. bday, notes, etc) that my current address book does not contain.
I have kernel panics while booting up as well as after completing the booting process. This has happend the second time now after updating to OS X 10.6.8. This is a report of the last one:

I got a 24" iMac, Processor 3.06 GHz Intel Core 2 Duo, Memory 2 GB 800 MHz DDR2 SDRAM My main problem is that whenever I restart my iMac, two problem reports emerge, neither of which can be sent to Apple due to an additional message which reads "Submission Failed: Your report could not be submitted. Please try again." Anyway, the report reads as follows:
Now, normally I probably wouldn't have such a problem with this, however, some times when I put my iMac to sleep, I get a grey screen with a folder containing a question mark and a "non" sign over it. I have no idea what this means but I usually cannot turn my iMac back on for a half hour before it works again.
I have a mid-2011 IMac running Lion 10.7.3. From the time I got it, last Sept., it has said it has a problem and has to shut-down and restart. Then a long report appears with all the codes and apps. listed to be sent to Apple.This was first happening ever 3-4 wee, then every 2-3 weeks, and lately I had 2 in one day. I always add in the comments section that I would like to know what is going on, but never get any feedback, can't read the code well enough, but CPU 2 seems to show up. aI talked to Applecare last week and got a problem munber. The rep. says those reports are used by tech services to see what changes to make, and not tied to individual machines. I am concerned that I may have a lemon that will give out after my Applecare expires. I'm not anxious for a replacement or having the screen pulled to get inside to repair it. I've got it set up too well to risk it.
My IMAC keeps prompting me to restart after the screen turns grey. Essentially, after a few hours of use, the screen turns dark grey, filling in from the top to the bottom slowly. Once the screen has the dark grey hue, directions pop up in the middle of the screen for me to restart the computer. Once I restart it, the computer automatically generates an error box to report to apple. However, when I click the box to submit to apple, even if when the computer is connected and running well, it will not allow me to report it.
Suddenly, Safari explodes with duplicate window and/or tabs for a single URL. If I click on a tab, I get the message that tabs must be closed to go to a new page. I approve this action, the windows disappear, only to have the next page appear with another pile of duplicates. Is this a virus?
Like many users, I have set up my only user account as Admin, which I share with my wife. I would now like to duplicate that user account (so as to keep all the settings, etc.) and convert the new account to Standard, and rename the Admin account to a new name.
I feel that I am running out of storage memery too soon. I have a feeling that while migrating all my pictures/videos from pc to mac I might have done something wrong an i have duplicate files. What will be the easiest way to check on this? I am not very familiar with the mac systems and I am scared to mess something up.
When I try to delete duplicate names and addresses from my Skype contact list I get the message that this has to be done by deleting these names from my Mac contact list. How is this done?
I am running Address Book 5.0 on Snow Leopard on one machine, and want to share my contacts on another machine running OSX10.4.11, Address Book v4.0.....can this be done?
I cant use my imac coz it has a self assigned IP address and wifi not be able to connect to internet. We actually change to fiber net. when fiber net was installed in our home that's the beginning of my wifi problem. The sad thing is only my Imac got the prob. the rest of the computers at home got signal. They said fiber network makes your surfing to internet even faster but its not what I expected. one imac and one mac book pro are functioning using wifi but slower than before .The only Imac which I am using is the only one that cant be used. any suggestions from u. I tried everything. unplugged, turn off routers, rebooth imac, rebooth routers. but it still the same the IP address is self assigned.
