Networking :: DHCP Server Auto-detect
Apr 1, 2010I have a scenario where a Debian (in this case) device will be connected to an existing LAN.What I then want said box to do, is to query the LAN to see if there is an existing DHCP server present. If there isn't one - then simply use the Debian box as the DHCP server (which works fine atm).If there is an existing one - I need the Debian box to be able to turn off it's own internal one and get it's details from the existing server (ie. change from server to client).
These action will need to be sat in the background as well - just in case another DHCP server appears on the LAN after this box does. Don't shoot me for saying it - but I know Windoze server does this. Is there a 'script/util' that anyone knows of (I am trying to do this auto-magically)?
Debian Multimedia :: XOrg Auto-detect Failing To Detect Max Screen Resolution
May 29, 2011I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.
Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.
When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?

Ubuntu Networking :: Proxy Settings: Allowed Hosts Instead Of Ignored Hosts
Aug 17, 2011Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.

Nov 2, 2010I am trying to make a bash-script for auto-logins on several hosts, seems there is a problem with the quotes and I can't figure it out. I've experimented with singles and doubles but no luck yet. Below are two variants with respective outputs. In both cases the output of echo works fine if I copy and paste it to a prompt, but when executed from the script it falls down.
* Only one case-clause for testing...

View 1 Replies View RelatedOpenSUSE Install :: Way To Turn The Terminal Auto-detect Off?
Jun 14, 2011SuSE 11.4 is a wonderful release, but two chronic problems remain. The most serious is the inability to get Gnome to recognize an intel driver parameter specification in xorg.conf or 50-screen.conf with a predetermined, working screen specification. With the latest update that includes: [url]
Gnome will boot up in a strange resolution with a display of a pink screen and fragments of icons split and duplicated over the display. Teasing open the terminal parameter screen, terminal parameters (resolution, horizontal rate) appear to be correct. The terminal type is 'undefined', whether the screen is operating correctly or not, and any attempt to set defaults are refused. Perhaps the intel driver has not been selected by the operating system. Is there a way to specify a default screen driver?
This has been a chronic problem, now aggravated with the latest update to the point where the computer is now rendered inoperative.
Ironically, the other problem, that of the difficulty in downloading certain update files also remains. Had an elaborate update workaround procedure not been followed, the system would still be usable.
General :: Auto Detect Text File Encoding ?
Jun 24, 2011There are many plain text files which were encoded in variant charsets.
I want to convert them all to UTF-8, but before running iconv, I need to know its original encoding. Most browsers have an Auto Detect option in encodings, however, I can't check those text files one by one because there are too many.
Only having known the original encoding, I then can convert the texts by iconv -f DETECTED_CHARSET -t utf-8.
Is there any utility to detect the encoding of plain text files? It DOES NOT have to be 100% perfect, I don't mind if there're 100 files misconverted in 1,000,000 files.
Ubuntu :: Auto Detect Hard Drive Errors?
Jan 22, 2010Someone explain this to me. I often thought in the back of my head, how do I check if my drive is bad in Linux? I always excused it thinking well I guess besides gaming that's another reason to keep a windows partition around. I boot up yesterday and Gnome was acting weird. Then, it happened. "We have detected bad sectors in your hard drive." I thought, no, you're stupid, this hard drive is less than a year old (however it was a replacement for another one that died). So I reboot.
Boot back up - Different error message. But instead of getting it a few minutes after log in, I got it right away. "We have detected potential hard drive failure." Okay, Linux. Want to play this game? Booted to Vista, downloaded Seatools to test my Seagate drive. It failed... Swapped SATA cables... it failed... So I ask - how does Linux have this auto detect capability like that? As much as I love Ubuntu, I was like there's no way it could just magically tell like that without running the Seagate program. But alas, Ubuntu was dead on target.
Ubuntu :: HIPOINT Does Not Detect Wireless Devices Auto
Jul 18, 2010I am running UBUNTU 10.04 on an X86 system 64bit. I am trying install a wireless keyboard and am not having much luck.
-My non wirelessUSB keyboard and mouse work fine.
-My wireless logictech mouse works fine without adding any special drivers/packages
-Wireless Keyboard (LX500, uses same receiver as mouse) does not work with standard config
-Adding HIDPOINT and selecting my wireless mouse and keyboard (LX500) - wireless key board does not work. Mouse still works.Since my wireless mouse worked before HIPOINT installation (64 bit), I believe HIDPOINT is not working.
HIPOINT Does not detect my wireless devices auto, must manually select them. So I believe that there is some conflict with other drivers.Can anyone point be in a direction to look? What are the typical configuation files and drivers used to configure standard USB mouse and keyboards? What are some other software that might be installed that is conflicting with HIDPOINT?

View 3 Replies View RelatedNetworking :: Ethernet Auto-connect / Auto-sense Doesn't Work
Feb 3, 2011I have noticed that a common issue to several distros is the fact that the networking subsystem doesn't automatically detect the link if an ethernet connection is disconnected and then re-connected to the NIC after boot. If the ethernet cable is connected after the system is up and running, nothing happens - ethtool eth0 shows link detected: no, and you have to restart the network service to let the NIC know that there is in fact a link, and actually connect. I have a Fedora14 (KDE) box with a brand new Asus motherboard with embedded NIC. Everything works great except the auto-detect of a freshly connected ethernet connection if the link is down to begin with.
Am I missing a ethernet link sentinel utility or something, or is this just the way linux works? I have done plenty of research on plenty of posts, and it seems this is a common problem, with no solution other than manually or programatically restarting the network service in a script to detect the link after a disconnect.

May 17, 2011I've followed all the instructions in nagios documentation to install the nrpe agent in a remote host, but the daemon nrpe is not listening on port.. that means I can't even test it localhost!
netstat -at | grep nrpe
returns nothing.
You added the nrpe entry to your /etc/services file - done
The only_from directive in the /etc/xinetd.d/nrpe file contains an entry for "127.0.0.1" - done
xinetd is installed and started - done
Check the system log files for references about xinetd or nrpe and fix any problems that are reported - syslog empty..
Installed lsof and lsof +M -i4:
xinetd 25680 root 5u IPv4 75987 TCP *:nrpe (LISTEN)
Is there anything else I can do to correct this? I configured this yesterday and it was working ok.. but today when got into computer it stopped working
