My sysctl.conf in /etc isn't loaded at boot, it does however get parsed with the command # sysctl -p I believe this problem started when I got the 3.0.0 kernel just a few days ago. Does everyone has this problem? Then it's probably a bug.
My system:
Debian Testing (Wheezy)
3.0.0-1-amd64
up2date
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.

View 1 Replies View RelatedOn a production Centos 5.3 system, I want to raise the hard & soft limits of open file handles from 1024 -> 8192 (not a "biggie", I'd think) Right now, "sysctl -a | grep file" shows fs.file-max=463144 (a default, I'd guess) I'm guessing file-max is the maximum number of open file handles on the system, vs the per-user limits seen with "ulimit -Hn" and "ulimit -Sn". Right? If so, I shouldn't think I'd have to touch this on a server with few users.
Also, after doing a lot of reading, I still don't understand the mentions of needing to also add: "session required pam_limits.so" to /etc/pam.d/loginor adding "session required /lib/security/$ISA/pam_limits.so" to /etc/pam.d/system-auth Maybe I've gotten off into the deep weeds in goggling about raising file handle limits.
im trying change my etc/sysctl.conf file but it won't let me as its read only. how to i change this?
View 2 Replies View RelatedHow do I make a change to this file? More specifically this is what I am trying to do.
Add the following line to /etc/sysctl.conf
vm.swappiness=10
How can I find the size of units in sysctl.conf e.g whatis the size of the shmmax variable i.e. is it byte kb , Mb etc....???

View 8 Replies View RelatedLast 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.

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'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"
View 12 Replies View RelatedA couple days ago I installed Debian Lenny (netinst) to my friend's laptop, a IBM Thinkpad T23. Got a black screen after gdm loaded and the laptop seemed frozen. Decided to upgrade to squeeze. I edited the apt sources file and changed all the instances of lenny to squeeze, and then upgraded.Had the same display problem, but found a web site that suggested disabling acpi. So I did that, got the sound working, (needed cs46xx firmware), and all seems to be running fine.I get some weird udev messages at boot time, but I have a feeling that's due to how I upgraded. I can't copy and paste since the messages aren't in my system log. If anybody wants more information about it, I can supply it. pgrep shows two instances of udev running so it appears the messages are only warnings.When upgrading to squeeze, I used tds.net debian mirror links. Earlier today I switched to Debian's official US repo URLs and had to upgrade about 250 packages after reloading package data.
Now, when I click on System -> Administration -> Time and Date.After a couple seconds I get a dialog box that says "The configuration data could not be loaded" in bold black letters. Underneath that in smaller letters, "You are not allowed to access the system configuration" I receive that same error when accessing "services" and "users and groups."But I can access the synaptic package manager and update manager from the administration submenu.
I run Debian Squeeze on my Lenovo ThinkPad W500. Today I tried to use the expresscard slot on the device and was disappointed to find that it didn't work. A bit of digging revealed that the pciehp module was not loaded (but is required for hot-plugging these kinds of devices).Can anyone explain to me why this is the case? All other hardware on my system has had the module auto-loaded on boot-up, but why not pciehp for my expresscard slot?
View 2 Replies View RelatedI have recently installed Debian 504 AMD64, when I try to access "System" --> "Administration" --> "Users and groups" logged in as root, I get the following message:
"The configuration could not be loaded. You are not allowed to access the system configuration."
The system does not even ask for a password and the result is the same if I log in as a normal user.
I have installed from a single ISO DVD downloaded from the internet and read the DVDs of my previous Debian distro to install packages not included on DVD 1 of Debian 504 although I do not think this unusual approach can have any effect on the installation. I suspect I'll have to boot in single user mode but I have never done any troubleshooting at the command line.
(/etc/passwd and /etc shadow look OK).
Debian 2.6.32 Squeeze + GnomeI try to start System | Administration | Services and I get an error:The configuration could not be loadedAn unknown error occurredI turned on a whole bunch of different services and suddenly now I can't get back in to switch any of these on or off. I'm assuming there is some manual way of switching these off again, I just don't know where to do this.
View 3 Replies View RelatedBecause the version of the microcode installed by the package intel-microcode in Testing (2009-03-30) is way older than the one currently offered by Intel (2010-02-09), I only installed the package microcode.ctl and let it fetch the microcode. However, after reading the Read Me files, manual pages and system logs, and checking the directory where the microcode is stored, I have not been able to find an option to check the version of the microcode in use.
This is the output of update-intel-microcode:

My Debian workstation is on a predominantly Windows network. It is resolving internet addresses (i.e. www.google.com, etc) just fine. However it's not resolving any of the address of machines on the local network and the windows machines do not resolve the linux machines address either. All machines (linux and windows) can access each other just fine via direct IP reference.
My /etc/resolv.conf file has the following IP addresses listed:
127.0.0.1
10.1.1.111
10.1.3.4
10.1.1.111 is a netgear VPN/router that is the primary router for the LAN and maintains a VPN to a remote office 10.1.3.4 is the IP address of the Windows Primary Domain control on which the DNS server is running. That server is at the remote office. The system acts like it is completely ignoring anything I put in the resolv.conf file. From the linux X server I'm using "Network Setting" utility to make changes to the network configuration. This appears to work fine for things like switch between DHCP and static IP.
I'm trying to get the latest Lenny running on some old hardware (a Winterm 3150se). Everything is working just fine except for two things.
When Gnome starts, it comes up at 1600x1200 resolution, which is too high for my monitor. It shows a portion of the right side of the display, If I select Screen Resolution, it gives me a few standard choices, but if I pick one, it acts like it's trying to honor my request, then comes back as 1600x1200 again.
My xorg.conf file had no references to Modeline, so I added a 1024x768 Modeline, not really understanding where the selection I was given was coming from. Anyway, it didn't help.
I can see in the log file that right after the entry about using xorg.conf, it says 'Module "ddc" already built-in', which must have something to do with it?
My hardware supports all the usual video formats, at least it does when it's running WinCE. Is there a way to force the use of xorg.conf or can someone tell me why DDC is acting like it's "read only"? Is DDC a file somewhere?
My other problem is that the Winterm refuses to not try to boot from the flash memory thumbdrive even though it's formatted as a non-bootable device - it's my SSDisk. I have to boot without the drive in, then slip in in just as the boot process exits the blue start screen. I can live with this problem, since it might be dumb hardware.
I just system-upgraded (testing) to kernel 2.6.38. All seems ok, except that a few things I added to xorg.conf in the past (basically, keyboard language switch) have no effect anymore. My xorg.conf is still there, it is still the same as before, but the changes I did in XkbdLayout section have no effect. It seems xorg.conf is not used anymore. I assume new version of xorg uses a different configuration file, but I'm not sure.

My /etc/resolv.conf file is normally just set up to use Google's public DNS:
When I connect to the network at the university library, it totally overwrites my /etc/resolv.conf file to something like:
This is pretty annoying, so I tried comprimising by making a file with the school's domain and search entries plus the Google nameservers, then revoking write permission on the file. However, I couldn't access any domain name with this config on their network, so I reverted to using their nameservers. I keep all the school's entries commented out when I connect to my home network.
My ultimate question is what is actually overwriting the file? I suspect that my connecting through DHCP is responsible. Whatever it is, I'm pretty annoyed that no back up file was created.
I have used /etc/fonts/local.conf to control how the fonts looks like in my laptop, which runs a Gentoo. In particular, I don't want anti-aliasing.
