View 2 RepliesI am using putty to interact with Linux server. I have started a process using putty.
The process is running and will take 5-6 hours. I want that process to keep running after I close the putty session. How can I keep that process alive after closing the putty session? I do not want to keep the computer ON all the time. Is there any way to do this?.

Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.
View 5 Replies View RelatedAs part of my transition moving away from Windows altogether, I've been trying to get the VPN to work properly under Ubuntu 10.10 32bit, through the wifi connection. The provider is Ivacy, using PPTP, and the usual instructions (below) are followed: [URL]. The VPN originally connects fine, browsing etc works all fine, for a limited period of time though. Within roughly 10min the connection stops working; I'm not yet sure whether the determining factor is time or bandwidth, but it remains short-lived...
There is no indication of the VPN connection dropping, it seems to remain connected, but no packets are received. To get the internet working again I have to manually disconnect from the VPN; then I can browse without the VPN, or reconnect the VPN and it will work for another small lapse of time. In addition, I'm not sure if this related, but after reconnecting a few times to the VPN as described above, eventually I get an error message, "failed to start the VPN service" (or words to that effect). The VPN connection worked very reliably under Windows.
I have been using FC10, it works well with wlan for sometime and goes inactive after some time and hence network goes unavailable. Even after few attempts to reconnect doesn't help. Rebooting helps in bringing it back temporarily.

View 1 Replies View RelatedI have v 10.10 and I had to hook up with ethernet cord to download and activate both broadcom b43 and sta drivers. Once they were both downloaded and activated my wireless worked fine. (Also I have an hp mini 210-1000 if that helps.) After unplugging my laptop and using it, if it dies or if things are running really funky and it seems like it could use a restart, or on one of the many occasions where I am not going to be using it for a few days and just shut it down, as soon as I start it back up.
I find that sta driver still says activated under system - admin - additional drivers, however the b43 now says inactive, and my wireless wont connect to any router, even though it can detect them, until I connect with the ethernet cord and redo the whole driver activation for both, and then restart. This happens every time, and although I don't often take my laptop out of my room, my router is away from my desk, so this is a major inconvenience when i have work to do, or if I were to ever take it out somewhere with me.
My network become inactive but on GUI show that network active. When i ping out the network, is response times out. I need inactive the network and active back but sometime also fail reactive it. What main problem. CentOS running on vmware

When I go to the Network Configuration Panel I see the following:
Status: Device: Nickname: Type:

Tried to activate and it states Activating network device pan0, please wait... determining IP information for pan0.... A few minutes pass by then. It indicates it failed. Cannot activate network device pan0! I have disabled the Controlled by NetworkManger and enabled the Activate device when computer starts.
i encountered the following:
situation:
1 server with centos 5.4 running 1 client with centos 5.4 - gnome running thin ethernet network
on my client desktop i have a link to a shared folder on the server. this works fine.
to the problem: after working with this (using the link and seeing it working) i shutted down the server from my client (in a terminal screen, using ssh) the terminal screen signalled the server going down and the connection ended. the linked folder on the client desktop changed its icon fine.
after that i clicked on the changed icon (of the link that was not a working link any more) and the client machine froze.... no reaction any more. i could only end the session by >ctrl-alt-f#< , log in and shutdown.
Q: is it normal Centos is that angry when you click such a link?
I am running fedora from the USB. My computer is Dell - inspirion. I tried to configure the wireless according to the instructions. I added new a device ...
I see the new device but it's written inactive. The Active/inactive buttons are disable (or not seen at all). How can i resolve/Active the wireless?
I just installed F15 on a laptop that previous had F12 working well. During install, it finds my wireless card and seems to set it up fine. The full install ran with the wireless active without any problem that I could see. Now, when I start up, I see Network Manager tells me that the wlan is active, but it doesn't show my specific network. If I click on the NM tray icon and open up the panel, my network is shown but it is not "active".
I can double click on it and it will become active - shows the little globe next to the antenna. This works fine for about 2 web pages worth and then FireFox 4 stops being able to find web pages. If I go back to the panel, double click on my wireless network (which looks like it is active already), and reactivate it, I can get the page I was looking for in FireFox, but within a couple of minutes it will stop.
Likewise with yum, while I'm installing software, I'll occasionally get errors like this:
[URL]: [Errno 14] curl#6 - "Couldn't resolve host"
If I reactivate my wireless network in the NM panel, it continues fine. Other computers/phones connected to this network seem to work fine. Is NM known to be problematic in F15?
I've got a wireless problem on my laptop (dell inspiron 6400).I don't know when exactly and why, but every time I watch a video on ..... or allostreaming, after a while (a few minutes), my wireless disconnect and it's impossible to get back any connexion.

Does anyone know what could be causing a Remote Desktop connection to a 10.04 box to be closing after some period of time? I have three systems all running 10.04 with Remote Desktop enabled. I'm using UltraVNC on Windows 7 to connect to them. If I open a connection and leave it open for a long time (like overnight, for example), when I come back in the morning, I still see the VNC window but as soon as I click on it, it closes. I can immediately open a new connection to the box but it now shows two active connections. At first I was thinking maybe there's an idle timeout value but given that Ubuntu still seems to think that the original connection is active, maybe the problem isn't on the Ubuntu side but on the UltraVNC side?
View 1 Replies View RelatedI just recently updated wicd from backports on lenny to version 1.6.2.2. And with my static ip configuration in wicd, when i click on the Scripts button in the network profile properties window the gui part of wicd totally freezes. This literally means that the tray icon becomes unusable although the connection stays alive. I would like to setup some scripts to automatically activate my vpn connection through pptp, which already works manually, but i would like to do it somehow through wicd. The wicd wiki talks about it vaguely so i figured i try it. I also tried to post this question on the wicd forum but registering is disabled for the time beeing.. though luck i guess.
So anyway does anyone else has these sympthoms with the backports version of wicd ?

I'm forwarding an application (HandBrakegui) over an ssh tunnel using X11 forwarding as follows
ssh -C -p PORTNUM user@host -X ghb
This all works fine and X11 loads and handbrake's X11 output to my local mac.The server is Ubuntu 10.4 and the client is Mac OS X.Is it possible for the X11 HandBrake Gui session to be kept alive once the SSH tunnel or the X11 window on the client (mac) has been closed? As I'm adding files to HandBrakes queue I want the programme to finish encoding them even if I turn off the client computer as the server is always on.
I have an ESXi session i need to keep going because it kills the cp command when it logs out or times out. So I need something that can press enter in that window every 5 minutes.

How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?

I am running Fedora F14 on an Intel I3 cpu w/4Gb memory and plenty of disk. I have two displays connected to the Gigabyte Motherboard, one of the HDMI connector, and one on a DVI connector. I run Gnome. When Compiz is enabled things work fine for a while, meaning hours or days. Then the displays will "freeze" to the point where the clock stops updating. The system itself is still running programs, services, and the mouse and keyboard work. The mouse cursor will move around, but nothing can be clicked upon. If a terminal was the open window, typing on the keyboard does not do anything, nor does ctrl-backspace or whatever it is to terminate X windows. The keyboard does allow me to press ctrl-alt-F2 to switch to one of the base consoles. Once there I can type to my hearts content. I can kill off my logged in Gnome session through the console, and I can shutdown the system in a controlled manner.
It is as if all of the windows stop updating. For example, I play music through Amarok. An hour after I stop using the system but letting the music play the screens will do their lockup. The clock will stop, and Amarok will stop updating which song it is playing. It continues to play each song in the playlist, but the Amarok window shows what was playing at the time that the clock stopped. I've also had this happen to me while using Yumex, where it would stop updating the screen while installing programs, but the programs do get installed. With Compiz off I don't have this problem.
The version of Compiz I am using is currently 0.8.6-3. It is running on Gnome 2.32.0-2, with a Linux kernel of 2.6.35.9-64. It has happened with earlier versions of these programs. I am using the graphics processing the Intel i3 chip to the motherboard connectors. The freeze generally happens at some random time while I am not actively using the system. It has happened to me while doing simple things like programming through an IDE. The really strange thing to me is that the cursor will move around on the screen after everything else stops updating.
