Software :: Unable To Make Ptpcam Working - ERROR: Could Not Open Session

Jun 25, 2010

After finally getting libptp2 to compile I find that ptpcam does not work. This has worked perfectly fine before with the same camera using Slackware 12.0, I am now using Slackware 13.1 and ptpcam will simply not work. The error is as follows:

Code:

x86_1# ptpcam -l
Listing devices...
bus/dev vendorID/prodID device model
ERROR: Could not open session!
Try to reset the camera.

I have tried to reset with "ptpcam -r", I have also tried to disconnect and reconnect the camera to the USB system, I have tried to reboot the computer, I have tried to use different versions of libptp2 -- all to no avail. The strace shows the issue is apparently a failed ioctl(), although I have no idea why it fails:

Code:

open("/dev/bus/usb/002/004", O_RDWR) = 6
write(4, "1"..., 1) = 1
read(3, "1"..., 1) = 1

[code]....

I have verified that the camera is working in Windows 7 on the same physical computer and I can see the camera from lsusb and dmesg output when I connect it to the USB system. This system is Slackware 13.1, Linux x86_1 2.6.33.4-smp #2 SMP Wed May 12 22:47:36 CDT 2010 i686 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux.

OpenSUSE Install :: Cannot Open ConsoleKit Session: Unable To Open Session

Apr 11, 2010

The following message comes up when I boot up: Logging in user Warning: Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 0. When I press OK, the system completes the start up and everything looks normal. But when I try to connect to internet, I get the following message:

KNetworkManager cannot start because the installation is misconfigured. System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution. KNetworkManager will not start automatically in future. If I reboot the system, I logg in successfully. So far the problem has appeared approximately upon every second time I boot up. Rebooting the system seems to take care of it.

Don't know what info is of interest. I'm using

Opensuse 11.2
KDE 4.4.2 (Factory)
After upgrade from 4.4.1 to 4.4.2 it worked fine for a week or so.

Fedora :: Unable To Open The Session

Feb 1, 2010

Just installed Fedora 12 on a P4 IBM. Everything installed fine. Then, I rebooted, installed updates, and installed a few simple programs (emacs, ssh server). I rebooted since some kernel updates had been made. I can't login anymore. I get a brief message at GDM that says "unable to open session" after I enter my password. Root also doesn't work, but I figured out that root logins are disabled. I found something that recommended disabling selinux, so I reboot with selinux=0 parameter. That still didn't fix the problem, but did initiate selinux to re-label everything on the next boot.

My next thought was that maybe my password got corrupted, so I went into single usermode. I ran passwd justin, so I know that my password is correct. I still can't login via GDM or on a tty.

EDIT: I was also thinking I might need to uninstall something that I did; however, networking is disabled in single usermode, and if I init 3, then I get a login prompt that I can't open. Is there a way that I can enable root login? That might be a starting point to see if it's my user account or a general login problem.

Fedora :: Virtualbox Error 'Failed To Open Session For Virtual Machine Windows 7'

Jun 6, 2011

When i try to create a virtual machine using the Windows 7 Enterprise Evaluation iso file, everything goes as planned untill i click on the start button. when i click on it i get two error messages. the first: Failed to open a session for the virtual machine Windows 7. The virtual machine 'Windows 7' has terminated unexpectedly during startup with exit code 1. Kernel driver not installed (rc=-1908). The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. reinstall the kernel module by executing

'/etc/init.d/vboxdrv setup'

as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary. i have installed the DKMS package, but when i try to run the command stated in the error message, i get another error message in the terminal:

[code]...

i have to install the driver that is specified (vboxdrv) but i do not know where to find it.

Networking :: Unable To Open Socket (Not Available Error)

Aug 12, 2010

I've been tasked with transferring a Python web server from a Debian box to a Fedora server for work. (I think) I've been able to transfer all required files but I'm unable to run the web server because whenever I make the HTTPServer call in the python file I get an error "Cannot assign Requested Address".

I've basically traced the issue back to the server being unable to open a socket on the requested port (8085 in this case). I've checked netstat and there are no processes running on that port (or any other one I've tried for that matter) so wondering if there's a system configuration I need to do to allow programs to bind to sockets. Is there a deny configuration set up somewhere I need to modify? Does this even make sense?

Ubuntu :: 10.10 - Unable To Open Software Center (Value Error)

Apr 23, 2011

I am not really new to ubuntu since I had it for time now I still don't know a lot about it since I was not really interested in exploring it and probably won't understand some of the terms used so go easy on me. Now, since I have upgraded to ubuntu 10.10 (maverick) (maybe even earlier since I haven't been using it much) I have not been able to open Software Center.

Trying to openit through terminal gave me the following result:
Code:

Ubuntu One :: Error: Unable To Open Address Book

Jun 13, 2011

When trying to copy my personal address to CouchDB I get this error: Unable to open address book. This address book cannot be opened. This either means that an incorrect URI was entered, or this server is unreachable. Detailed error message: Invalid source

I have been trying (since 10.04!) to sync my Evolution contacts. UbuntuOne seems to be the most promising way of doing that automatically, however, I completely fail at accomplishing this seemingly simple task. I have NEVER been able to successfully back up my address book to UbuntuOne. Note: all other sync works fine. It's just Evolution that is seemingly smarter than I am. Thing I have done to solve the issue:

- Upgraded from 10.04 to 11.04
- All three steps from this article:
https://wiki.ubuntu.com/UbuntuOne/FA...olutionSyncing
- Cuss and swear and roll my eyes, mutter a few unrepeatable curse words about Canonical and their mothers.

None of this has solved my issue.

Fedora Servers :: Sendmail[31427]: Unable To Open Berkeley Db /etc/sasldb2: Unknown Error 13

Sep 7, 2010

I've been using cyrus and sendmail together for a very very long time now. Just recently I upgraded to fedora 13 and now my virtual users can not send email from the /etc/sasldb2 passwords. I get in the /var/log/messages sendmail[31427]: unable to open Berkeley db /etc/sasldb2: Unknown error: Its weird that they can still log in and get email from imapd.conf

sasl_pwcheck_method:auxprop saslauthd

[code].....

I even tried re-creating sasldb2 and sasldblistusers2 shows my two users 'one' that is also a local user account and the saslauthd authenticates when sending emails, but the virtual user 'two' can't send just only can log in to receive. /etc/sysconfig/saslauthd is set up as mech=pam. but I don't see how that would be relevant to this issue.

Fedora :: Cannot Open ConsoleKit Session

Oct 31, 2010

My Fedora 12 box got that error after some updates on it.

I can login but it's prompting that error and everything will be a black space.

But still no good.

According to the log messages, the ConsoleKit session isn't initializing. I can't paste the logs here coz it's on another laptop.

I could think of just upgrading it to Fedora 13 but there's no way I can backup all of my files on it. Is it just safe to upgrade it?
