Fedora Networking :: Vpnc On F12 Broken / Rdesktop Client Opens A "black" Window And Goes No Further?
Jan 9, 2010
I'm having problems with vpnc on F12 that work fine on F10 and F11. On F12, I can connect and can do some activities, but so far I noticed the following (show-stopping) issues:Attempting to connect to an Oracle database using either sqlplus or TORa hangs and eventually times out. I tried both the 11G and 10G instant clients.Copying a file to the host via a smb:// mount in nautilus freezes. An empty file is created though.
A rdesktop client opens a "black" window and goes no further. I attempted to downgrade vpnc on my F12 workstation from vpnc-0.5.3-4.fc12.x86_64 to vpnc-0.5.3-3.fc11.x86_64 to no avail. I also downgraded libgcrypt too and this didn't help either. Moreover, I upgraded these to the F13 rawhide version - still no luck.
I also confirmed on a F11 virtual machine that these work and that it doesn't work on 2 x64 and 1 x386 F12 machines. (The configuration and the host are the same in all cases.)

In fc10 & fc11 everything worked well with vpnc.
With fc12 vpnc starts allows me to connect to my work site then everything works fine til I try and start a remote desktop connections to a windows client use tsclient. All I get is a blackscreen and my laptop is hung.
At work without the vpnc it works fine if I start the vpnc from nm it performs the exact same way and I get the blackscreen.
I have disable selinux.I also disabled the firewall
there was another gentlemen on here with the same issue.
The only way out is a hard reboot and there are no messages in the logs that say there were any problems.

Whenerver I try to log on to our Windows 2008 R2 server via rdesktop, the window stays at the same small size. I can neither enlarge the window at the borders nor maximize it. Alt+Ctrl+Enter simply gives me the same window-content on the full screen with the rest simply grey.
Is that normal behaviour for rdesktop? Is there an alternative?

I've been trying to connect to my office Cisco VPN several time using the network-manager-vpnc GUI in Ubuntu Karmic with no success. I read a couple of articles and i tried using the direct command line way:
Code:
sudo vpnc office
with the following /etc/vpnc/office.conf file:This is fictional data
Code:
IPSec gateway vpn.office.com
IPSec ID office
IPSec secret 0ff1c3
which worked perfecly.
So i went back to the Network Manager GUI way and i used the same credentials. Same fictional data I got a libnotify message telling me it couldn't connect.Anyone know how i could troubleshoot this issue? Would be great to have it integrated in gnome instead of running a background command which is not tracked by nwm.

Spice server/client configuration. I used remote viewer on debian jessie to connect to a guest virtual machine on kvm and everything works fine. It used a spice server / client and qxl. After I upgraded to debian stretch, I suddenly face issues with black bars in the remote client window. Those black bars appear only on the left and right side of the remote viewer window. Also in full screen mode the black bars sadly appear. Maybe the scaling mode is somehow disabled or my screen resolution of the host was wrong calculated related to that i can change the guest screen resolution but the spice remote client keeps its window size with the black bars. I was trying the last couple of days to resolve this issue, unfortunately without success.

Thunderbird has been running on my Fedora 13. After a recent yum update, it opens a tiny window in the upper left corner of my screen, which I can enlarge manually. There are no contents in the window. I cannot see anything.

I have setup a vnc server using the "every imagineable server" thread which setups up VPN using xinetd. I have also installed Beesu and its associated scripts so I can easily open root privileged nautilus windows.
beesu works a treat on the actual display. However whilst vnc'd into the box I get prompted for my root password (which it accepts) but a nautilus window never opens. No errors, it just doesn't open.

since yesterday when I open up an explorer style window, say I browsed folders in Gnome for each folder it opens a new window. However; when I go to change it so it does it in the same window either through edit properties or system/preferences/file management it does not open and instead a bugzilla window opens as it crashes (taking my desktop with it until it refreshes)

My system boots, I login and am brought to my desktop. I click on the file system icon in the launcher to open a Nautilus window. The window opens, but is unresponsive (i.e., I can't move it, clicking on the icons does nothing, etc.). If I press the super key to get the dash and the press escape, the window becomes responsive again, just like normal.
If I open a folder in the window, the window becomes halfway unresponsive in that I can't move the window, but I can select more folders and toolbar icons. The top menu no longer appears at this point, and I can't access any of the system icons on the top right of the screen. Alt-F4 closes the window even if the close button doesn't work.As another example, suppose I open a Nautilus window and then a Chromium window. Both are immediately unresponsive. If I super-esc again, I can move the Chromium window around, and it seems to work normally. I can click on the Nautilus window, but it always stays greyed out. Even if I'm clicking on things in it, the Chromium window always has focus.
I had a similar experience to this with VLC and Chromium. After clicking around enough I eventually got it to the point where VLC apparently always had focus, but I couldn't access any of VLC's controls. Double clicking anywhere on the screen fullscreened the video, and that's all I could really do. Not even escape worked to bring it back.I can usually press super to get the dash and Alt-F2 to get a command prompt. Also Alt-Shift-T seems to usually work to bring up a working Terminal (at least one that accepts commands, even if I can't move the window).Does anyone have any ideas on what might be causing this? The behavior is highly unpredictable and extremely frustrating. I should note that key commands don't always work, even though they seem to in my examples. So I don't think it's just a mouse issue.

Since I installed FC11 vpnc stop working. I get "vpnc: no response from target." I tried running it with "strace" and the reason is a timeout: poll([{fd=3, events=POLLIN}], 1, 4000) = 0 (Timeout)
I tried google and adding "NAT Traversal Mode cisco-udp" to the config file works for some people but not for me Does anyone had experience with vpnc 0.5.3 in FC11?

I have been trying to connect to my University's VPN Server and for some reason vpnc fails. I have configured the vpn settings the same way I did for the past two years. They worked properly on Fedora 12 and 13, but for some reason fails on Fedora 14.

how nobody else could have run into this in the meantime. [URL] Two friends of mine are having the same issue on Ubuntu-11.4-machines. In short: Connecting to the Cisco-VPN via shell-command "vpnc" works flawlessly, whereas NetworkManager just doesn't connect at all. We had this working in older versions of Fedora/Ubuntu about some months ago...

I am having problems accessing my work desktop through my home computer running Fedora 13. I am able to remote into work through MAC and Windows XP. I loaded vpnc and was able to connect to the concentrator. I also able to ping it too. I cannot connect to my desktop using rdesktop. I get error message �Unable to connect, socket is unavailable. I cannot ping to the desktop.

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).
As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message
Quote:
Failed to bind to 0.0.0.0:500: Address already in use
[user@computer ...]# vpnc-helper --local--port 0
If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.
If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.
Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.
Does anybody have an idea how to enforce that the vpn connection is actually used?

I am using KNetworkmanager-vpnc to VPN back to the office from home, the vpn connection works fine - for 15 minutes then I am disconnected. I am fairly certain that this is related to the Phase 1 key lifetime limit. The Knetworkmanager-vpnc GUI does not provide a location to enter this information. I think I found the config file that holds the connection information at /home/<user>/.kde/share/apps/networkmanagement/connections/ I just don't know the proper syntax to put in the file to specify a key life limit. Anyone out there know how to do this? I am using Fedora 14 x64 with knetworkmanager-vpnc 1.0.9-0.28.

every time i play a file, vlc opens a new window for that file and does not close the already running file... I find it inconvenient to close the previous window in order to listen to a new song.
Is there any way to automatically close the previous file as soon as another is played?

I have seen when people click on an icon that is on the doc, it opens up a pop up window that has application you can click on. I have Cairo Dock. With it, I can add a shortcut menu and a Stack icon. From there,I can add applications, but they have a generic *.desktop icon. Is there any way to get the same Mac effect from Cairo Dock, or maybe even a shortcut to the applications folder in Ubuntu?By the way, can someone tell me the default path to the applications folder?"

In Pidgin browser preferences, it's set to open in new tabs. But when I click on a link in IM, it opens in a new window instead. Is this because I use Google Chrome in the Incognito (Private Browsing)?

I am trying to write a simple client that opens a secure connection. My intent is to use the OpenSSL library.
I am following this tutorial: [URL]... The tutorial mentions that I need a trust certificate store called TrustStore.pem. However, I can't find that on my machine. Is there a way to generate it? I separately downloaded the source from the OpenSSL website. The source distribution doesn't have it either. There is a whole bunch of .pem files. Can I use any one of them?

For any usb drive Gnome opens window for each partition -- how to disable this?
I am OK if Gnome mounts them. But I would like to have some settings and decide for which drive which partition I would like to mount.
Related thing. With google I saw suggestions to use gnome-volume-properties
But it is not there any more - Ubuntu 10.04.

I"m running 10.04 on a netbook. I switched my Java look and feel to Nimbus and now my java application opens with most of the buttons and window content missing. The main menu is there, but otherwise the main form is mostly blank. If I restart the application (not my computer) 2-3 times, the problem is resolved until the next time I have to launch the java app. I did not see this issue before changing the look & feel setting for Java. But the GTK l&F doesn't work for other reasons, so I was forced to make a change.
I'm running compiz and I know the blank windows in Java apps was a common problem a while back. I'm not sure if what I'm seeing is related to that old problem or is something different.

So this has happened to me several times with fedora 12, and granted I havn't rebooted in a while but it seems that after I update and reboot, I cannot log into GDM any longer.I can login to the CLI, so and I checked all my logs to make sure it wasn't an authentication error.What does happen though, is when I try and login to KDE the screen flickers likes loading the desktop and then spits me back out to the login prompt.var/log/messages reports successful login.Here is what i did find
** (process:2220): DEBUG: Greeter session pid=2220 display=:0.0 xauthority=/var/run/gdm/auth-for-gdm-H2QyqS/database

If any window opens initially on full screen (maximized) the "desktop effects" switch off. I then have to reset "enable desktop effects".
It happens with any window from any application that opens full screen.
If a window is maximized after it has already opened all is fine, it does not stop the desktop effects.
Running: openSUSE 14.4

I have Suse 11.4 and GNOME 2.32.1 When I click on Computer -> Places -> Home then VLC Media Player opens instead of the window with my home folder that should actually pop up. The same thing happens with all other icons in the Places tab.
