Anyone help?

[SOLVED] netctl-auto not working, and I cannot remove netctl instance

Hi, I installed Arch a few days ago, netctl-auto was working yesterday but today it's not.
Note that
netctl start
works: I have a problem with netctl-auto only.
$ ping -c 3 8.8.8.8
connect: Network in unreachable
I have created only one netctl profile so far, it's called wlp4s0-VM581389-2G (wlp4s0 is the name of my wireless interface)
$ ls /etc/netctl
examples hooks interfaces wlp4s0-VM581389-2G
$ netctl list
wlp4s0-VM581389-2G
wpa_actiond is installed, and I have done
systemctl enable [email protected]
But for some reason I have some extra netctl@ instances that shouldn't be there. I am wondering if they could be the cause of netctl-auto not working properly:
$ systemctl | grep netctl
[email protected] loaded active running Automatic wireless network connection using netctl profiles
● netctl@my\x2dnetwork.service loaded failed failed Networking for netctl profile my-network
● netctl@wlp4s0\x2dVM581389\x2d2G.service loaded failed failed Networking for netctl profile wlp4s0-VM581389-2G
system-netctl.slice loaded active active system-netctl.slice
system-netctl\x2dauto.slice loaded active active system-netctl\x2dauto.slice
- What are these bullet points at the beginning of these two lines?
- Where do netctl@my\x2dnetwork.service and netctl@wlp4s0\x2dVM581389\x2d2G.service come from? They might be instances that I had enabled in the past.
These instances are not enabled and they are inactive, but they are loaded!
$ systemctl is-enabled netctl@my\x2dnetwork.service
Failed to get unit file state for [email protected]: No such file or directory
$ systemctl status netctl@my\x2dnetwork.service
● [email protected] - Networking for netctl profile myx2dnetwork
Loaded: loaded (/usr/lib/systemd/system/[email protected]; static; vendor preset: disabled)

Docs: man:netctl.profile(5)
I have tried to get rid of them, but not managed:
$ systemctl stop netctl@my\x2dnetwork.service
$ systemctl disable netctl@my\x2dnetwork.service
$ systemctl | grep netctl

system-netctl.slice loaded active active system-netctl.slice
system-netctl\x2dauto.slice loaded active active system-netctl\x2dauto.slice
Also, I have tried to check with
netctl-auto list
, which gives an empty output. I am guessing that it's normal, because the netctl-auto instances are managed by systemd?
Now, trying to understand what is happening to [email protected]: as seen before with systemctl | grep netctl, it is active and running.
Then I do:
$ journalctl -u [email protected]
-- Reboot --

wpa_actiond[310]: Starting wpa_actiond session for interface 'wlp4s0'
So, a wpa_actiond session was started, but I still cannot ping 8.8.8.8. Why?
Investigating further:
$ netctl status wlp4s0-VM581389-2G

"You may have another wpa_supplicant process already running or the file was left by an unclean termination of wpa_supplicant in which case you will need to manually remove this file before starting wpa_supplicant again."
What does this mean? Which file might have been left by an unclean termination? I tried to find this info in the wpa_supplicant documentation, and by searching on Google, but couldn't find anything.
Now I am lost:
- how do I get rid of these two undesired netctl instances?
- where can I investigate next, to get netctl-auto@wlp4s0 to work?
Any help greatly appreciated :-)

What is the output of:
ls -l /etc/systemd/system/multi-user.target.wants
netctl-auto cannot be used with explicitly enabled profiles (ie, those for which you have used `netctl enable <profile>`).

[SOLVED] WIFI connection is not working

Yet Another WIFI issue
When I try 'wpa_supplicant -i wlan0 -c <(wpa_passphrase "mylongssid" "mylongkey")'
I receive this error:
Successfully initialized wpa_supplicant
wlan0: Failed to initialize driver interface
I was on my wifi at home this morning surfing the web and then I went to school (So I hopped to a different WIFI in other words)
It seems no matter what I do with netctl, iw, wifi-menu, and ip link that nothing works. Currently I do know how to set wlan0 up/down, restart my netctl profiles, display iw stuff, scan with iw, etc.
But I do not seem to know enough. Can anybody help by providing some debug commands?

Some Broadcom chip that has b43 firmware.
I will post the output of the lspci in a few moments. I have to transfer some output via a flash drive.
Here is the output of some stuff:
http://pastebin.com/8vNyHZWs
My drivers worked fine this morning at my house, and they usually work at school after a reboot. So I am not sure why you need driver info. My question was what debug commands can help me diagnose my wpa_supplicant error? As in what log files can I check? If I could find a log with a more descriptive error, I might be able to fix my WIFI. Or possibly some logs for netctl? I really do not know, since networking is usually magic in all the easier linuxes I have used in the past.
Thanks for the really quick responses by the way I have never had such a fast help response for any other distro.
Edit: I should note that both my home and school networks have the same type of WPA security.
Update: When I booted my labtop at home, I ran wifi-menu and voila my home network was working. I will try the WIFI at school again tomorrow and post another update after that.
Update 2: Running wifi-menu at school worked today. I have no clue why it did not work yesterday. (I really should setup netctl-auto)

Adobe bridge raw not working with windows vista in photoshop cc, why?

adobe bridge raw not working in photoshop cc, is there a fix?

Your sure your using photoshop cc on windows vista?
I was under the impression that photoshop cc would not even install on windows vista.
What version of camera raw do you have?
In photoshop under Help>About Plugin does it list Camera Raw and if so which version is it?
(click on the words Camera Raw to see the version)
Camera raw doesn't work if it's a camera raw file or some other file type such as jpeg or tif?
What camera are the camera raw files from?
Officially camera raw 8.3 is the latest version of camera raw that will work on windows vista.

Partner application logoff not working

We have a partner application registered with sso with custom login screen. The login works fine. We use the following code to logoff the partner application in logoff.jsp
response.setHeader("Osso-Return-Url", "http://my.oracle.com" );
response.sendError(470, "Oracle SSO");
session.invalidate();
but the logoff is not working properly. It is not invalidating the session and the logout http request is not going from the application server to the sso server.
Are there any additional configurations for SSO logoff.Any help is appreciated.
Thanks

Hi
The WF should also trigger if i add the Partner function in UI.If i change any Attribute the WF triggers but i dont want to change the attribute when i add the partner function.
If i have only one event for WF that is Partner Change the WF will not trigger it for the 1st time when i save the UI. But next i come to the same saved doc and add a partner function then the Wf triggers.
So this means that Partner change is active.
the issue here is i need to trigger the WF on , the 1st time i save the UI, for which i wil be using Attribute Change and next time when i come back to saved doc the and add only the partner function and no changes are made to attributes the WF should again trigger.
Thanks

IPhone 4 Voice Memos not working/saving

Hi there,
I'm having trouble with my voice memos too. Up until yesterday they were working fine and now, even though the record button works, the stop button does not and I can only pause them. Worse again is that the button to go into the menu to view all voice memos is not working so I can't play them from my iPhone and nothing new is saving to my iTunes. Please help!

I've always had the "Include Voice Memos" option selected. I think that only pertains to syncing voice memos from iTunes to the iPhone after it has been copied to iTunes. It has to be the new OS/iTunes not communicating that new memos have been recorded. For some reason they won't sync when I want them to, and then a few syncs later they magically appear.
By the way, I'm VERY comfortable with the iTunes and iPhone systems. I've been using iTunes for 5 years, and I've been recording class lectures with the iPhone voice memo app (and another app) for a couple years. It's not an error of not seeing that the memos were added; they don't exist in my library or music folders.
JUST OUT OF CURIOSITY, POST WHICH FIRMWARE YOU ARE RUNNING EXACTLY!!!
I'm on an iPhone 4, running firmware 4.0.1

Installed Premiere Pro CS4 but video display does not work?

I just got my copy of CS$. After installing Premiere I found two things that seem very wrong:
1) video display does not work, not even the little playback viewer next to improted film clips located on the project / sequence window. Audio works fine.
2) the UI is way too slow for my big beefy system.
My pc is a dual boot Vista-32 and XP system with 4GB of memory installed and nvidia geforce 280 graphics board with plenty of GPU power. The CS4 is installed on the Vista-32 partition. My windows XP partition on the same PC with Premiere CS2 works great and real fast.
Any ideas how to solve this CS4 install issue?
Ron

I would like to thank Dan, Hunt, and Haram:
The problem is now very clear to me. The problem only shows up with video footage imported into PP CS4 encoded with "MS Video 1" codec. So this seems to be a bug. The codec is very clearly called out and supported within various menues but video with this codec just will not play in any monitor or preview window. In addition the entire product looks horrible with respect to performance while PP CS4 trys its best to play the video. Audio will start playing after about 30 seconds. And once in awhile part of video shows up at the wrong magnification before blanking out again.
My suggestion to the Adobe team: fix the bug and add some sample footage to the next release so new installations can test their systems with known footage.

Polygonal lasso tool not working with stylus on Surface Pro 2

Hi guys,
I'm new here so please bare with me if I'm posting in the wrong place or don't make immediate sense.
Hardeware / software used: surface pro 2 and I'm running photoshop CS5.
Problem is a fairly basic one: I am trying to make basic selections using the polygonal lasso tool (using the stylus that comes with the tablet) but it simply will not work. All I get when I touch the stylus to the screen is the circle that appears then fades. If I attach the keypad and try using that then it works no problem at all.
Does anyone have any ideas as to whether there is a particular setting that I need to switch on or off e.g. something relating to pressure sensitivity (although not sure why this would affect this particular selection tool)?
I've searched the web and come up with nothing so far so any help is greatly appreciated!
Thanks for your time
Scott

same problem on surface pro 3 !!!!
and i think quite significant, for lot of artists using polygonal lasso a lot (including me). How come that the stupid surface cannot work properly

Excite PRO 3G connection not work after Android v4.3 update

Hello,
I live in Italy and on last Sunday (january 26th) my Excite PRO tablet (model AT10LE-A-10H) got the Android version 4.3.201121220.35.
After restart my wifi works fine, all other app work fine, but my 3g connection doesn't work, mobile network bar is empty and it says "no service".
My sim card is ok. I used this sim card before the system update and I didn't get any problem with Android 4.2.2.
Please help me.
Thank you

>After restart my wifi works fine, all other app work fine, but my 3g connection doesn't work, mobile network bar is empty and it says "no service".
Go to the mobile network settings and search again for the 3G network.
I had similar problem with my Android Smartphone and my o2 provider
I started new search, then I chosen the O2 again and then I could solve the problem.
In case this does not work for you, recommend you to reset the tablet back to default (factory settings)
