Red Hat / Fedora :: Unable To Connect To Existing Vnc Session
Jul 1, 2010
We are using Real VNC enterprise server. User will connect to the vnc server and do their work. We are facing one issue since from last week. When user is working on session, some times the session will get hung.He can't do anything on that. If he close the connection and try to connect from vnc viewer to the same vnc session it is not connecting. even it is not asking for the password. I have checked in the server the Xvnc process for the session is still running. When I tried to check the session is alive or not from telnet it is not showing that RFB 004.001.
xhdvnc2 ~]# telnet localhost 5902
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
If users are running some important tasks on that session they are not able to access. We are using RHEL 4U7 .

I've got two ubuntu machines and i want to connect via ssh into a existing gnome session. (or a new one if that is possible) VNC works fine(well slow and unresponsive) but when trying ssh i get problems. After som trial and error(some permissions on host, i did sudo startx and screwed up) i logged in and could start xterm. Anyway now i want to use gnome, so i wrote "gnome-session" - something i read would work but i got ALOT of errors.
Code:
gnome-session[6094]: WARNING: Unable to find provider 'nautilus' of required component 'filemanager'
** (gnome-settings-daemon:6104): WARNING **: You can only run one xsettings manager at a time; exiting
** (gnome-settings-daemon:6104): WARNING **: Unable to start xsettings manager: Could not initialize xsettings manager.

I want to be able to add a physical drive to an existing filesystem, and PRESTO! That filesystem has more storage and/or redundancy. When one of the physical drives eventually fail, no problem, Ive lost some redundancy, I just have to install a new drive before another one fails.Lets assume I have 4 physical drives.*What Is This Configuration? *[URL]...But I am unclear how to get a logical volume that is mirrored and linear.
The last time I tried software RAID 1 (dm-x) under lvm, it was very fragile. Systemd could not start it,and then an update to mdadm put a stake through its heart. So I know that does not work.

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.

Have you guys had this weird nautilus error? When I su to root and run "nautilus" in terminal, errors popped out:
Code: (nautilus:3979): EggSMClient-WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported(nautilus:3979): Eel-WARNING **: GConf error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

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.

I was wondering if there was a way to connect over ssh "backwards". For example, lets say there's a client connected to example.com via ssh from behind a router. Well you wouldn't be able to ssh to that client unless the proper ports were forwarded on the router right? So I'm wondering if there would be a way to connect to example.com through ssh then from there connect to the client using the already existing ssh connection.

Im having some issues regarding AD authentication.
I have the PC running Ubuntu 8.10, it has likewise installed and is working great except for one problem.
We have currently two domains. One is called FS and one is called PIONEER. I joined the PC to FS, and can authenticate to FS perfectly (using FSuser at login), but when trying to Authenticate to PIONEER (using PIONEERuser at login) it just sits at the blank background and doesnt load the desktop at all.
What am I missing? Is there an conf file i need to edit?
Here is output of my auth.log when I try to log in using the PIONEERJpionner login
Code:
It looks as thought its not lauching the session.
Also, I am able to get in with PIONEERJpioneer using the failsafe terminal, but upon logon it gives me:
Then it acts normal.

I am running Debian Squeeze with XFCE. I have installed gdebi, but when I try to run it as gdebi-gtk it gets to the point of password entry, lets me do this then closes before installing the package. It worked fine for the first few, and it works as gdebi from the command line, so I can only guess that it is linked to something with gtk graphical front end. I tried removing using apt-get remove and reinstalling as well as purging the cache and checking for broken dependencies.
This is the output when I run gdebi-gtk from terminal

I have a brand new Slackware 13.1 x64 installation, and I'm having problems with slapt-get.
I'm unable to upgrade existing packages or install new ones. The output in terminal is:
Code:
bash-4.1# slapt-get -i tar
Reading Package Lists... Done
The following NEW packages will be installed:
tar
[Code]....
Worth mentioning also, I managed to install Gnome from [URL] without any problems immediately prior to this error message starting to appear.
I've been using Debian and Ubuntu derivatives for the last couple of years, so I'm comfortable using the terminal and possibly doing some more advanced stuff.

Just installed Fedora 13 (64-bit). Brand new to Linux and not much of a computer expert.
As the subject line says, I am unable to connect to the Internet.
Things that I have already tried based on threads posted for similar problems:
* ping -c 5 www.google.com
unknown host www.google.com
* ping -c 5 74.125.159.105
Network is unreachable
I connect to the Internet via wired ethernet. The modem/gateway is 2Wire mod. 2701HG-B. Service provider is AT&T DSL. Ethernet controller is Realtek Semiconductor RTL8111/81688 PCI Express Gigabit Ethernet. When I go to System -> Administration -> Network Device Control it shows eth0 as inactive.
Network Configuration shows:
* Hostname: localhost.localdomain
* Primary/Secondary/Tertiary DNS: blank
* DNS Search Path: blank
I have no problem whatsoever connecting to the Internet when using Windows XP.

I've been using 3 different distros for the last 2 weeks. Ubuntu, Fedora and Mint. And i've been using Windows since I can remember. I won't talk here about the benefits I got with Linux, because everyone knows that. But there's something about Linux that keeps annoying me, no offence to Linux users, and I want to ask you about that.
It just seems impossible to install additional software without an Internet connection. I tried: Keryx, Opyum, Suhi,huh?, Synaptics generate download script, yum -downloadonly. I didn't yet: Debian 10DVD I'm not programmer, and my knowledge about computers and operative systems is very small. But installing software on Windows the worst case of dependencies i saw was I had to download just one more .exe file (.NET framework or klite codec pack installers, for example).
question: Is there any Linux distro or any way where packages are managed in a more compact fashion? Suppose I want to use Wine, how I download some megapackage with ALL dependencies or something like that? How system administrators manage where no Internet connection at all (if that possible)?
