I have a strange problem with my networking under Ubuntu. When I first log in to Gnome both my network adapters are listed as "disconnected" in the network manager applet. If I right click on the notification icon and disable networking, then wait a few seconds and re enable it, it works fine.
It's happening consistently with Maverick although it seemed only temperamental with Lucid. I did a fresh Maverick install to see if it would help but it hasn't.
It's the onboard network sockets on a Gigabyte GA-X58A-UD7. I have two ports but I only use one, it doesn't seem to matter which I use. It's connected via gigabit ethernet to a Netgear router. It works fine in Windows 7 (dual boot).
It looks as though something's not quite "ready" when gnome first launches. The light on the router for the cable is off at first, and only comes on after a few seconds. It's DHCP. Same thing happened on the live USB stick (just before the isntaller) and disable/reenable made it work.
I have just installed ssh-server in my Ubuntu 10.04, and really want to know how to enable/disable it and I also want to be sure if the changes will take effect after the next boot or not, and how to do that?
My wireless can connect to my router without a problem, but in order to do so (after boot) I must first disable networking in the Notification Area and then re-enable it. I don't mind it too much, but when other people use my computer, it's made painfully obvious to me, that this was never an issue with Windows 7 (as much as I despise MS).
I'm running Ubuntu in VMWare for a side project. I noticed when I boot up, it doesn't let me access anything externally. I have to disable network manager and re-enable it. Once done, I can hit everything fine. I'm using a static IP in network manager.
Disable internal wireless card & enable external? Can I do this really by network-manager or should I use some other program. If I plug-in external both are connected. If I disable internal by laptop button, I cannot enable wireless anymore in nm-applett (external on).
Adapter: Ralink RT3090 802.11b/g/n Wi-Fi Basically, whenever I disable it, I can't get it to turn back on. If I hit Enable, it says device is not ready. What can I do to make it work ?
Im new to this Cent OS as well as Unix based Operating Systems. Please help me with the below requirement.My Company is a Serach based data collector from different websites like Google, Yahoo & many more..Collecting the data from the search engines is a issue for right now.. As many search engines are blocking us to search and retrive the date after some time.. Taking Google as example : Google Blocks my IP after every 30 mins of retriving.. Application is a Windows based & using Windows 2003 as the Server.. Would like to give a Dynamic IP to the Windows Server via 1st Ethernet Card & enable the 2nd Ethernet for the Internet..Eg : eth 0 = 192.168.1.1eth 1 = x.x.x.x (Public IP)I have check with few of my friends who told me to get Linux or Cent OS installed to do a interface disable after given time & enable a secondary device or virtual interface the next couple of seconds... Like eg : eth 1 = x.x.x.1 eth 2 = x.x.x.2 eth 3 = x.x.x.3 so on.. Would like the eth 1 to be down after 60 mins & eth 2 o be up & again after 60 mins of up time eth 2 down & eth 3 up.
I have a server that NFS exports the /home directory out to other computers. On the desktop they all work great, but on a wireless laptop, this is where the problem occurs. The wireless enables after the person logs in, rendering the NFS export /home useless on the laptops.Is there anyway to have the wireless enable correctly on the boot so that NFS can mount properly at boot also?I'm using Fedora 11 (32bit) with a wireless router that has a security of WPA-PSK [TKIP] + WPA2-PSK [AES]. I could switch to some of the older versions if necessary to get this working.
I've had a host of problems since upgrading to 11.04 Natty Narwhal, so let's deal with these 1 at a time.
I've got a Hewlett-Packard Pavilion G60 laptop. Next to the power button is a handy wireless on/off button. This has always worked well with previous editions (9.04,through 10.10). first press toggles the wireless off, second press toggles it on.
Not so in 11.04. The toggle off works great, first time. But, it will not toggle back on. Not after any number of tries, not after restarting, not after booting into other OS's (9.10 and Vista) re-enabling it there and then booting back into Narwhal. to further complicate the issue, this feature bypass the network manager, so toggling the wireless off by the switch leaves me showing no wireless adapter in the network manager. I also restarted, switched from Unity to a Gnome session, but the issue still persists.
As my only network options are wireless, this has become a substantial inconvenience. ---- EDIT: so the network util is actually saying "wireless disabled by hardware switch". Also noticed it I enable it in 9.10, reboot to 11.04 (where I inevitably fail to re-enable it), then reboot into 9.10, it will initially be disabled. The key difference is in 9.10 I have the ability to enable wifi using the hardware button. It seems that 11.04 is remembering that wireless is disabled between boots. Is there a place it might be storing this value? If so, I may be able simply to set the value as enabled, since toggling that silly button isn't working. ----- EDIT 2: found this thread:"Wireless disabled by hardware switch" bug? - Natty seems to be a similar issue. I'll be following how that one develops, too.
I noticed that when my server boots up, it's network interface on eth0 is always down and I always must run the 'ifup eth0' command in order to get it to work for some reason. I checked my configuration and it looks legit to me...
Code:
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface
I have an issue with my on-board wireless card (powers down after about 5 minutes) so I'm stuck with a USB card. I don't use the on-board card and it causes the system to intermittently hang if it's powered on (once I run ifconfig wlan0 down, the system runs fine). Is there a way to power down the interface (or better yet prevent it from powering on) at boot?
I've downloaded from the Ubuntu software center a touch-pad application that allows me to set some preferences to my touch-pad. So since I rather use a mouse, I've disabled it, the problem is, it only keeps disabled for a few minutes, later it works again. So I want to keep disabled until I enable it again, any suggestions?
is there a way to enable/disable specified hardware? Allow me to explain, i have 2 wireless adapters, one integrated and one USB, i want to use the USB adapter for 5Ghz 802.11n and the integrated wifi adapter in my system is the one ubuntu is defaulted to.. i have the drivers for the USB device already installed i just need to disable the integrated device.
I am able to get my touchpad to enable disable from the bash shell using
Code: sudo modprobe -r psmouse with or without the "-r" to turn it on or off, respectively But I wanted to write a script to do this for me because "mouseon" and "mouseoff" is easier for me to remember and more convienient. But I am having some issues (I am a complete newb at scripting, so forgive my ignorance)
the script written is:
Code: #!/bin/bash #enable/disable touchpad
sudo modprobe -r psmouse I have saved this script as "mouseoff" in usr/bin (echo $PATH told me this was a directory bash searches, even though it was not a directory and I had to create it with mkdir).
then I did Code: chmod 755 mouseoff However, when I try to run it, I get a "permission denied" error.Can anyone help me with what I am doing wrong?
I just finished the update. Though everything seems to work just fine hardware wise... somehow it was decided that I'd prefer netbook remix over the standard install. I hate it! I can't seem to find any way to get the standard desktop mode back, and I feel like after the upgrade, my fan has been working overtime for some reason. Can someone point me in the right direction to disable netbook remix? I really cant stand it.
I used it for a while and got used to it. Then I pressed something (I don't know what) and the global menu bar disappeared and the menu now locally appearing in all windows.
I recently upgraded from Lucid to Maverick I can't seem to disable screen lock after resume from suspend. It's a minor annoyance, but still a considerable annoyance to have to enter my password every time the computer wakes up.
I've thusfar
1 - changed screensaver preferences to not lock
2 - set the gnome_keyring_hibernate, gnome_keyring_suspend, hibernate, and suspend, values all to false in gconf-editor
3 - commented out the line LOCK_SCREEN=true in /etc/default/acpi-support
BUT am still being prompted for a password every time the computer wakes up from suspend. I'm stumped, what could I be forgetting?
how to disable gstreamer???? (and be able to re-enable it also?) i don't want to totally remove gstreamer - as it is required by alot of software. however, when i am using proaudio apps with low-latency having gstreamer enabled is a problem. this is because ( i think ) that my crappy intel-hda (STAC9200) only has one sub-device, while many other cards have multiple.
so when gstreamer is there, i will get more xruns, and a nasty message in dmesg, something along the lines of "intel-hda switching to polling mode". overall performance of the card will suck. BUT! if gstreamer is NOT there, i can run low-latency(2ms) with pretty much no xruns(jackd). the only time i get the odd one is if i am switching drum banks in a wine VST.
well, i remove pulseaudio when i install Fedora, gstreamer doesn't work properly after that, you can't use rhythmbox, or anything. but you will get much better latencies and generally the card is very useful. ie: i can manipulate many sounds/samples/synths in realtime, or actually record in ardour with a decent load...
Sorry but I'm a new user and would like to know how to enable/disable firewall. I have tried to open a port up on my firewall but, for some reason that didn't work. I have found these command in another thread: $ sudo /sbin/chkconfig iptables off $ sudo /sbin/service iptables stop I assume this is to disable the fire wall. How do I enable it once I'm finish running my program.
I have 4 computers and I currently have 4 USB cradles so every time I want to switch to a new computer I have to unplug the keyboard/mouse dongle and replug it in the appropriate cradle. I would prefer to connect the single dongle to a 4 way USB switch then choose the target computer by remapping 4 of the keys I don't need, for example:
Anyway, according to the release notes, RHEL 6 has a PAE enabled kernel by default. Great... But that leaves me wondering why uname report SMP. Further, I'm provisioning some systems for QA use, and they're asking that PAE is disabled. My thinking is that since RHEL 6 requires PAE capability to install, there may be no way to disable it and the googling I've done seems to support this. tl;dr Why does a default kernel with PAE enabled report SMP on RHEL 6?
Is there a way to automatically enable or disable spellchecking in vim depending on the filetype? I often work with tex files (with lots of text) where the spellchecking is useful, and scripts and conf files where spellchecking often marks variables and functions (which are often in red or similar colour), making them unreadable (red text on red background).
