Networking :: Ntp.conf : Settings For A Refclock Using Symmetricom Bc635PCI Timing Card?
Feb 5, 2010
I have setup a box using RHEL-5 inside a private network, no outside connections, and I've got a Symmetricom bc635PCI-V2 clock card installed and working. It's getting GPS time via IRIG-B feeding the PCI card from a TrueTime GPS receiver. I need to setup the NTP software to use the time from the PCI card. Which means I need to setup a /dev/refclock-? symbolic link to the driver as far as I know? I can't find any documentation on the bc635 card that associates the refclock to the driver. Does anyone know what settings I need to use in the server line of the ntp.conf file?

Last week I attempted to get "up to speed" with my Comcast cable connection... Ubuntu 9.10, Dell Vostro 400 desktop, Firefox 3.6.13... Comcast says I should have 12 Mbps connection... if I get 1.0 Mbps, I'm doing good... they just tested everything, and said everything is fine on their end. They use [URL] and connects to a server in Chicago, 60 miles away. That gets fantastic speeds, and it's a durn shame the internet doesn't store all its files there!! I use [URL] for my tests, and it uses a server in Dallas TX.
I go to my girlfriends house, and her AT&T DSL line has d/l speeds of 4.5 Mbps or better!!! She's running XP Pro on a Dell machine. So, started digging on the web and thru the forums, and found this:
[URL]
But, like ALL too many things, it's dated... it's from 2008... I've set my settings to what is there, and disabled ipv6 in Firefox. Hey, now, I'm sometimes up to 1.4 Mbps!! Also found this, but no date...
[URL]
Reading forums, I see that folks have said there is a network connection problem with 9.10... and then I see that others are saying the same thing about 10.04 and 10.10!! I have 10.10 on my laptop and had to fight to get its Atheos card to be recognized. Running some tests [URL] gives me weird results: Download 2.64 Mbps, Upload 4.12 Mbps. NOT what it should be. Similar results from testmy.net.
Dunno exactly what info is needed... Speedguide.net gives me results below, but I've tried changing numbers (says my RWIN is low) and nothing changes:
--------------------------------
TCP options string = 020405b40402080adf1dca100000000001030306
MTU = 1500
MTU is fully optimized for broadband.
[code]....
So, today, find, once again, that I'm d'ling in the range of 90/KB/s (719 Kbps)... disgustingly slow. I go on my HP laptop and run the test, and it says 1.6 Mbps. So, desktop directly connected to router is not even 1 Mbps, and wireless connection is faster? Neither of which is close to what I should be getting...

I am having, just installed a fresh 9.10. The only thing I did was an update and installed the wireless drivers. Well i went to to download my favorite browser Opera and firefox just times out. I can get to other websites just fine so far. Though it looks like Office Depot won't let me in either. If I boot into Windows I can connect to either site just fine.

I'm running Kubuntu 11.04 on a laptop with dual monitor setup. I have Nvidia graphics card and I've successfully configured TwinView for the monitors. However, after saving the settings to xorg.conf (using the nvidia-settings application) X should use both monitors after boot, but only the main monitor is used. I first thought that X didn't read xorg.conf at all, but when I put some illegal statements into the file X wouldn't start and gave an error about the illegal statements. It is thus clear that X does read the file, but it just doesn't seem to use the settings in it.
Here is the contents of my xorg.conf file: [URL]

I have a complex network. ADSL broadband comes into the house and connects to an Orange Livebox. An Ethernet cable then connects the Livebox to a more powerful router, a DrayTek Vigor 2710Vn. The reason for this is that the Livebox has a second line capability using Voip, but it is not powerful enough to get around my stone house. The DrayTek router has Voip capability, but as yet Orange will not connect the Voip line to it. I connect to this system with Ubuntu. Android, Windows and I-phone. I can connect to either of the routers, though I usually use the DrayTek.
Voip on the Livebox does not require a computer to run it, you just plug a normal phone into it and use it to get free calls. I actually take this line into a Panasonic telephone switch to give me a 2 line system around the house. The problem with this set-up is that after a short time something happens to the network which prevents Ubuntu computers connecting to it. Windows machines, I-phones and Android phones connect, but Ubuntu does not. If I re-boot the Livebox, or in an extreme case take it back to it's factory settings, the Ubuntu machines can connect again, but it's only temporary.
The fact that fixing Livebox sorts the problem definitely points to Ubuntu being innocent, but at the moment I can't do without the Livebox. That means, for the moment, having to stay with Windows. If I post the output log after a failed connection attempt, all it would show is the connection timing out. Why is Ubuntu so sensitive to network problems that are not of it's making. Is there anything I can do about it other than changing my ISP. I am considering that, but other factors make that difficult.

Does anybody have experience with linux tuning. I`m realy interesting about sysctl.conf tuning settings for batch(3d rendering, phisycs simulations, etc.) servers. Does anybody has an experience with linux tuning - I mean memory and CPU settings for heavy loaded systems. What kind of settings You have in Your clusters ? I`m working with Red Hat Enterprise 5 x86_64.

I recently tried to install the proprietary nvidia driver to my laptop, but after disabling nouveau have run into a problem. When I start X I get an error
Code: (EE) No devices detected
Fatal server error: no screens found
I believe the computer is trying to use the on-chip intel card instead of the nvidia card because "dmesg | grep video" specifies "pci 00:02:0: Boot video device", "lspci | grep 00:02.0" gives me "VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
I have googled this issue all day and have not found a solution that works for me. nvidia-xconfig does nothing as doesn't "nvidia-xconfig --multigpus=on". Is there a way to specify which video card my laptop uses on boot? Maybe which my xorg.conf uses?
I will try to add my xorg.conf file later on.

I have a ATI Radeon HD 4000 PCIe card in my Debian system. I got the proprietary ATI drivers working (fglrx) but a kernel upgrade killed that. I was unhappy with this driver due to the very high memory usage. The card works with the non-proprietary drivers but I can only clone my desktop. I want a single desktop on two monitors.
I booted with Ubuntu Lucid and my dual monitor desktop worked out of the box without the proprietary drivers so I thought that I could emulate what Ubuntu does in Debian. But I can't.
My issue is that I don't know whether I am missing a module in the kernel or I need to set up a brand new xorg.conf. Ubuntu doesn't have an xorg.conf to copy. My default Debian doesn't either.
I have messed around with my own xorg.conf and added various drivers eg "ati" and "radeon" but I can't get it to work with a single desktop dual monitor display.

I installed Ubuntu 10.04 on my sister's laptop (it's a Packard Bell; not sure about the model, but I could check); it has two graphics cards: the primary is an ATI Technologies Inc Mobility Radeon HD 3650, and the second one is an Intel Corporation Mobile 4 Series. After installation, installed the ATI driver through the restricted devices manager (xorg-driver-fglrx package, I think), and after a couple of reboots, the screen simply went black after boot and I couldn't do anything (I couldn't even switch to a virtual console, and booting on recovery mode was the same). So I booted with the ubuntu live flash drive from which I installed it, and deleted the xorg.conf file, and now I have a GUI, but it uses only the Intel card. I would like to use the ATI card if possible, but the problem is, if I use a xorg.conf file set up to use the fglrx driver, then I have a black screen, and if I use no xorg.conf file, it automatically switches to the Intel card. I also looked in the BIOS for an option to disable the Intel graphics card, but it doesn't have it (it's a very simple BIOS). So, since there seems to be a conflict between both cards, is there a way to tell xorg to ignore one graphics card? (the Intel one, in this case?).
P.S.: Here I attach two Xorg logs: Xorg.0.log is the last one (without using a xorg.conf file, and using the Intel card), and the Xorg.1.log file is the one of my previous attempts at using the ATI card.
I forgot, here is the outpput of lspci:
Code:
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
00:01.0 PCI bridge: Intel Corporation Mobile 4 Series Chipset PCI Express Graphics Port (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 03)

I've been using ubuntu on a new desktop for a couple of months, but i had an old HP that was given to me in my basement. It has 384Mb of ram, and thats because i had a 256Mb stick laying around. I installed debian becuase it is more suited for older hardware (at least from what I've read). It installed fine, but it boots to a blank screen, and pressing ctrl+alt+F2 bring me to the command line. I checked /etc/X11/xorg.conf to change the driver to vesa, to find out my video card isn't even shown. I ran lspci and I found that it says my graphics card is Intel Corporation 82810E DC-133 (CGC) Chipset graphics controller (rev3) In the device section of xorg.conf, it merly says Identifier"Configured Video Device"

Finally replaced my incredibly antiquated Ti 4200 with a GeForce 9600 GT, but I'm having a few problems. The main one would be that I can't see anything when I drop to terminal (the monitor shuts off)- I could when I had a spare svga monitor hooked up through an adapter, but now I'm using dual DVI monitors. Do not have an svga cable to spare at the moment. The second seems to be a doublethink problem- a good while back when this computer was a fresh install, I could have sworn I had the option for the resolution 1680x1024- this is an *essential* resolution for twinview, because my second monitor is 1280x1024, and setting this widescreen to 5:4 is just... wrong.Simple restart solved the terminal issue (I hotplugged the monitors). Resolution thing is still a standing issue. I have a 1050 capable monitor, but the display portion is an inch shorter than the widescreen.

I've purchased Creative sound blaster. It's external usb sound card, which worked well as I plugged it in. In sound preferences it was setted to 'Analog stereo output' in hardware, and I've accidently messed up with Connector droplist in Output bookmark. As a result - silence in my speakers. I wonder what went wrong and where to search for it. The card is worked and it is supported by ALSA. Just some settings went wrong.

I have ubuntu 10.4 32 bit. I have 2x gtx 285's in sli that work perfectly fine in sli in windows (so its not a hardware not properly physically installed issue). But in ubuntu in the x server settings only one of the cards shows up. I was wondering if this is a 32 bit issue as in the past running 64 bit they have both shown up fine.

the solution of my monitor is much to small. So I tried to find out, where I can change the settings of my graphic card and monitor. Unfortunately opensuse only gives me the possibility to change it up to 600x800, which is by far too small. So I thought maybe I need to install a driver... so... there I am ... having question marks around my head and wondering how to install a graphics card driver on my opensuse 11.3.???
And where to find the right ones?
My graphic card is a Matrox Mystique (no 220 or anything else!!). I checked the website of Matrix to find my drivers, but it tells me that there is no driver planned for linux. Matrox Graphics - Support - Latest Matrox drivers for legacy products But I guess I am not the only person in the world who uses this graphic card on linux, so there must be a way to make it work!!

I've just upgraded from 11.1 to 11.3. When I go into Yast and try to invoke the Graphics Card and Monitor settings, nothing happens - I get the spinning circles for a few seconds and nothing after that. How can I get at those settings, and why doesn't Yast let me do that?

i installed suse (KDE) on my old notebook and now I'm trying to get the wlan to connect to our router and can't figure out how to get it to work. My card seems to work, the network manager even finds the router, but i just cant get a connection. I followed the steps of the "Getting Your Wireless to Work" thread and these are the results:
[Code]....
- i messed around a bit with the network settings and might have cluelessly broken something (or broken it more)
- i tried a usb-wlan-card as an alternative, which didn't work either, but could possibly have messed things up even more.

I can connect to the internet and browse. I'm wired and using DHCP on a Windows network. Updating Ubuntu or downloading programs takes hours for 52MB of updates. Why? I read some articles that mention Network Manager needs to be enabled at the .conf file. Can I edit this using GUI or command line only?

I've been scanning the apache2 docs for the past few days and have not come up with an answer my following issue:
In my httpd.conf file, at the very end, I have the line
Include conf/vhosts/vhost_*.conf
However, when I run apache checkconfig or try to start apache, it gives me the error:
httpd: Syntax error on line 993 of /etc/httpd/conf/httpd.conf: Could not open configuration file /etc/httpd/conf/vhosts/vhost_1.conf: Permission denied
It appears as if the Include line is correct - in terms of it grabbing the first virtual host conf file. However, I'm confused on the permissions. the /etc/httpd folder is owned by root:root, as are the subfolders. As a test, I chown'd the conf/vhost folder combination and all the vhost files to apache:apache to see if that made a difference, and it appeared to make no difference at all. The log files don't contain anything (assumed because apache isn't starting). If I place the contents of the vhosts in a singular vhosts.conf it works - with the permissions set to root:root. I'd like to avoid having to use one vhosts conf for the configuration I'm trying to achieve - as it would make my life a lot easier.

I have used nVidia my entire linux life (about 5 years clean and sober from M$). Recently, I have switched over to an ATI Radeon HD 5550 card. After many trial and error setups, I finally got the resolutions and screens set properly with a xrandr command, which I have now added to a shell script in ~/.kde4/Autostart. It has worked for me for a while now, but I really would like to get it set in the xorg.conf.d files so that I don't have to wait that extra few seconds after login for the screens to fix themselves.
Is there an easy way to take what xrandr does and export it to the xorg.conf.d files? If my video card recognizes my default monitor as DFP2 and the tv that I only sometimes use with this computer as DFP1, how can I ensure that the login screen for openSUSE/KDE4 appears on my default screen (an issue that drove me nuts a few months ago when I tried Ubuntu to see what all the fuss was about)?
My xrandr command that I use to fix it all is:
xrandr --output DFP2 --auto --pos 0x0 --primary --output DFP1 --auto --right-of
I am using the proprietary Radeon driver from the ioda repository. DFP2 is a monitor which has a optimum resolution of 1920x1200, and DFP1 is an 1080p HDTV. I can not reverse the output plugs for the screens even though my monitor is an HDMI monitor because I use the actual HDMI port on the video card to output audio to the television and the other plug is a DVI that I convert to HDMI for the monitor.

I recently installed Xubuntu on my old P3 laptop (Compaq Armada E500 if anyone is familiar). The laptop is a bit old, so both wired and wireless networking is done via PCMCIA cards. I have 2 cards installed, one for each purpose. I can't find the dongle for the wired card right now, so I am trying to use the wireless card. I am able to find the network I want to connect to, and type in the password since the network is secured. It tries to connect but then pops up again asking for the password (I know it is correct). Is this card supported by linux/compatible? I tried finding drivers online but the sites that had drivers were down.
