IPv6 sleep disconnet, howto restart network w/o rebooting?

Hi everybody,
I succeeded in making an IPv6 lan with a connection thru a server (also a Mac) to the internet; everything works fine. But as every Mac user I don't shut my Mac down but set it to sleep. And there is the problem I loose the IPv6 connection (the IPv4 connection works fine) with my ISP. I can't find any solution to this problem.
So, to be short, how do I reset the connection without restarting.
Some info:
- StartupItem in System Folder to establish a tunnel with gif0 to my ISP tunnel;
- Set up rtadvd.conf to broadcast global prefix.
Thanks for any help.

So, to be short, how do I reset the connection
without restarting.
I have spent the last couple of evenings pouring over books and web pages trying to find the answer to that same question.
If I find out, I will bring it back.
Good luck!

Powersave not restarting network properly after suspend

My laptop uses ethernet hardware supported by the sky2 module, which must be unloaded before suspend. Network has to be restarted after the module is reloaded or ethernet stays kaput. So, I edited my /etc/powersave/sleep like this:
## Path: System/Powermanagement/Powersave/Sleep_Modes

Problem is, powersaved doesn't restart the network like it ought to. The log gives me this:

Apparently network is considered already accounted for, but it isn't. I have to restart the script manually. What's up with this?

Umm... OP? Log doesn't say that network fails, but appears to indicate that powersaved does not try to restart it. I'll give it a shot but it looks completely irrelevant.
Edit: Well I'll be damned, it worked. Just a second, I'm going to do a bit more messing around...
Edit again: Hmm, strange, works without the 5-second wait now. Damned if I know what was up with that.

Restart Network services

I hope this isn't a repost but I was wondering if there is a way to restart network services in leopard, similar to this command in linux:
/etc/init.d/networking restart
I want to troubleshoot my connection to the router in my home, and my linux install works after giving this command, but leopard is having trouble.
Thanks
hah nevermind I found what I need

Mountain Lion won't sleep, shut down, restart, or log out.

Hi All,
After Mountain Lion my 2010 iMac 27" won't sleep, shut down, restart, or log out.
Basically most functionalities of clicking the apple icon are disabled - "About this Mac" doesn't work either.
Please help!
Before Apple fixes this, is there another way of putting my Mac to sleep or shut down?

Just adding another voice to the chorus. Since upgrading to Mountain Lion my computer will not sleep. The cursor freezes when I try to invoke sleep but the computer and monitor remain on. The cursor unfreezes when I tap the spacebar the way I would normally do to wake from sleep. Fortunately, shutdown, restart and logout function normally, so I guess I should count my blessings. This isn't my only problem with Mountain Lion, but I didn't want to muddy the waters on this thread with other issues.
Dual quad-core MacPro3,1

Left USB-Port dead after wake from sleep. Just restart helps.

I hoped Apples keyboard-Update today would solve my biggest hate-bug in this buggy POS called Leopard. It didn't.
As usual on my Leopard-Macbook Pro, no device will work on the left USB-Port after I waked the computer from sleep. Just a restart helps. I hoped this update to solve this, because it replaced among others "IOUSBFamily.kext".
Terminal gives a timeout error for the internal USB-Hub after wake from sleep. I assumed this should be related.
I'm really angry now.
When will Apple solve the most urgent problems in Leopard?
Was 10.5.1 just smoke and mirrors to make (fool people into...) people upgrade who intended to wait until the first maintenance-update?
Was Leopard Apples attempt to make Windows-Users more comfortable by putting in some heavy extra-bugs and blue screens?
FIX IT FINALLY! And f... don't wait for Macworld to release 10.5.2. It's desperately needed and the current state of Leopard will leave some people very sad at christmas after getting their first Mac. First impression counts and many more peoples first contact with the Mac will be at christmas...

Apple knows the problem and for some reason they are stumped on fixing it. this is so bad I can't believe it. On my macbook pro with Leopard installed, USB left port is dead after sleep. Only restarting can power it back up. I have to restart every day to use my external hard drive for time machine or when putting my flash drive in the port.
Come on already Apple. This is a SERIOUS, SERIOUS problem.
Fix it.

However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Featurs appin the Window Control Panel. Then reinstall all the Apple software components

Mail Fails To Connect In My Office Network, Works on Reboot

This is baffling me and my network admin:
Mail fails to connect to any of my accounts at work. But it recovers if I reboot my machine.
Here is what happens:
- Mail works just fine at home. Connects to gmail, iCloud, and a 3rd party email account no problems.
- I get to the office
- I log in to the office WiFi with my password - for this I have to open a browser window, and enter my credentials.
(I kind of assume that this is the problem ^^)
- All my internet connections work fine, I can use the browser to access Gmail etc
- Mail refuses to connect to any of my email servers, and all accounts go offline
- Connection Doctor says "Mail can connect to the internet" but all individual connections are red, not reachable. I checked "detail" too - its empty.
Then I reboot my Mac, and after that everything's happy. Mail connects to my accounts normally, and Connection Doctor marks all as green.
Since it works on reboot, we can rule out network problems like closed ports etc. So the only thing I can think of is that Mail initially tries to connect as soon as I am on WiFi, then hangs (because I am not logged in yet), and somehow this hang is of a kind that does not recover (I've left it on for hours at a time, no difference, it never recovers).
Anyone have any ideas about this? Is there some way I can restart networking daemons to kill the hung connections. Or any other way I can diagnose this?

A captive portal, which is what you have, can work in any of at least three ways: by HTTP redirection, IP redirection, or DNS poisoning. I'm guessing that yours is the last type. In that case, a TTL of zero should be used. If the TTL is non-zero, then Internet applications may not work until the DNS cache is flushed. That happens when you reboot.
You should discuss the possibility with your network admin. If the network configuration isn't going to be changed, you may be able to avoid the need to reboot by flushing the DNS cache manually, as described in the article linked below:
OS X: How to reset the DNS cache

My wifi wasn't working for more than 10 minutes at a time after updating to IOS8 and resetting network settings. I turned off google drive, turned off Bluetooth, reset network settings and rebooted my iPad4. So far so good.

I have an ipad4. Wifi keeps cutting out after the upgrade even after I forget the network and resign on or reset all network settings. I deleted iCloud drive from my iPad, turned off Bluetooth, reset network settings, and rebooted my iPad. Since I upgraded to IOS8 this is the longest wifi has consistently been working for me. Which is approximately an hour now. Anyone else find that this worked or have figured out if this or anything out there is a permanent fix?

Hi CollinGCC78,
It sounds like you have been on the right track in troubleshooting this issue. If you are still having issues, you may want to double-check the steps outlined in the following article, in order if possible (apologies for replicating any steps you have already taken):

Lenovo Ideapad U410: Display not working after sleep and/or restart

Hello all,
I am recently having some inconsistent display issues with my Lenovo U410 laptop i7 1TB with a Windows 8 PRO upgrade (came with windows 7).
When I press the Power Button on my laptop to put it to sleep, the Screen turns black as if it is off, but the Power & Battery LEDs on the front of the laptop remain on, as well as the LED on the power button. However, when I try to wake my laptop, there is no response on the screen (remaining black as if it is off). The internal fan is running, however I receive no feedback when "blindly" trying to input my password.
I've tried to turn the power off and back on to no avail. I've also removed the power source and held the power button for a couple of seconds and that did not solve the issue either. I've tried connecting the laptop to a screen via HDMI (since there is no other AV port on the device), but there was no signal being sent through.
This is an inconsistent issue that began yesterday 6/11/2013. When the laptop is left alone for a little and is turned on again, the display works, but after closing the lid (sleep) or pressing the button, the display fails to turn on upon awakening.
In most recent circumstances, Today (6/12/2013) I was installing a Windows update that required my computer to restart. When the update configured perfectly BEFORE it was restarting, but AFTER the restart, my internal fan began to work, but the display was not on.
Does anybody or Tech support know what may cause this inconsistent behavior? or know any solutions to this issue?

I am facing similar problem - post sleep & sometimes on touchpad event - the screen gets stuck & a strange array of gray screen comes or the existing screen's colors get distorted & the laptop gets stuck.
model - Lenovo U410; 64 Bit; Windows 7 Home basic;, Intel core i5 processor
I have upgraded display drivers but that hasn't changed anything. Any help is appreciated.

Sleep, overheating, and restarting issue

I have an iMac G5 with one 1.8 GHz G5 processor. Lately, I have had this problem, and I'm not even sure what to search for on the boards. If someone can point me to an article, I'd greatly appreciate it.
I have my Mac set up as follows: The screen saver turns on after 15 minutes of inactivity. My computer & my display should both go to sleep when the computer has been inactive for 20 minutes.
Lately, my Mac is not going to sleep. Instead, the fans are running very fast, my machine has locked up, and a message on the screen is telling me to power off my computer and restart it.
Is anyone else having this problem, and what exactly is going on?
Thanks,
--Peter

IPod classic won't sync after Sleep until G4 restarted

I've got an *80GB iPod Classic* (sw ver 1.1.2) that *won't sync* with my G4 Quicksilver (10.4.11) *after the computer wakes up from sleep*. If I restart the computer, I can sync with no problem, and I can disconnect the iPod and sync as many times as I like +as long as the computer doesn't go to sleep.+
My iPod is connected via a *Belkin USB 2.0 5-port PCI expansion card*. I can't remember the model number of this card, but I know a similar one would not permit my computer to wake up from sleep when it was installed.
I've consulted http://support.apple.com/kb/TA24639 and know some PCI expansion cards provoke sleep issues with the G4, but there's no specific information on what issues or which cards. The solution offered in the kb article won't work for me, either, as the Quicksilver's built-in USB is 1.0 (i.e. slow).
*Have I diagnosed the problem correctly* -- is the problem with the Belkin USB 2.0 expansion card?
If so, *is there a similar USB 2.0 card out there that doesn't induce sleep problems* (i.e. disk mounting problems after the computer wakes up)?

is itunes open when it goes to sleep? is the ipod plugged in when it sleeps? does unplugging & plugging in again the ipod make a difference?

Cannot clear screen saver picture after sleep. A restart is required to resume work.

A three year old iMac owned by a friend freezes after sleep. It seems the screen saver picture will not clear. A force quit or finder restart does not work. Only way to resume work is to restart the computer.

Turned out a bad USB device was preventing sleep. Once I removed it the display went to sleep like a baby.
