CentOS 5 :: Purpose Of Fs.file-max In /etc/sysctl.conf?
Jul 29, 2010On 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.

Aug 12, 2011My 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.

Mar 7, 2011Last 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...

Feb 24, 2011cups does not start with the server. When I try to start from the terminal I get the error message
cupsd: Unable to read configuration file '/etc/cups/cupsd.conf' - exiting!
cupsd: Child exited with status 1!
The log files show nothing. cupsd.conf exists. It is user - root and group - root with permissions set at 0644.
My interpretation of this is that the program is not launching from either boot or terminal for a fundamental reason. I do not quite see what that reason is .

Ubuntu :: X Doesn't Read Settings From Xorg.conf?
Jun 16, 2011I'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]

Ubuntu :: GDM Broken - Gdm-binary[230]: WARNING: Unable To Load File '/etc/gdm/custom.conf'. No Such File Or Directory
Sep 1, 2011I've had Ubuntu 11.04 installed on my desktop since it's release. Up until an hour ago, it was working fine. I clicked on an update from the update manager, now booting into a graphical mode is completely broken, (the start-up load hangs at 'Check Battery State ... [0k]'). I restarted my computer, and booted into safe mode, and launched the terminal. This all works fine. I then typed :
Code: sudo gdm start into the command prompt, hoping that I would be able to start things manually. Instead, it spat out this: Code:
gdm-binary[230]: WARNING: Unable to load file '/etc/gdm/custom.conf'. No such file or directory.
gdm-binary[230]: WARNING: Unable to find users : no seat-id found.
gdm-binary[230]: WARNING: Gdm Display: display lasted 0.070467 seconds
The last line was printed about 8 times, with slightly different times, before it gave up and failed. Some information which might help, I have Gnome 2, Unity and KDE (not sure which version), installed. My graphics card is the GTX 275, and I have driver the Nvidia driver 275.21. So yeah, I think the update has gone and moved custom.conf somewhere, but I have no idea on how to fix it. I have a graphics programming assignment due on Friday and I would be eternally grateful if I could get this fixed well before then.

May 24, 2011I need to add an option to my xorg.conf to enable "backing store", like this:
Section "Device"
Identifier "Miserable Old SVGA"
Driver "miserable"
Option"BackingStore""True"
EndSection
But I don't have an xorg.conf file in Natty. There are several conf files in /usr/share/X11/xorg.conf.d/, but I'm not sure which one to add it too (I can't find the Device section in any of them). I guess I don't even know if the "BackingStore" option is valid in the latext Xserver.
