When connected to a Wireless network, how can I use the maximum bandwidth in the network as I am finding that my network speed is degrading day by day as more users are logging onto the network. Btw, I am using Natty Narhwal.
View 1 RepliesI created a the class like this for shaping the packets with a specified bandwidth rate.....
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 15
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 750kbit ceil 750kbit
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 600kbit ceil 750kbit prio 0
For Our Requirement:-
I dont want to specify the bandwidth rate strictly like this rate750kbit ceil 750kbit,based on whatever speed is coming which should allocate the bandwidth rate for particular class...I need one application for finding the upcoming bandwidth & Is any other method is there for specify the bandwidth rate in a classes.
We have a sipmle office network set up that we also use use to connect to the internet, however of late the number of users has increased thus slowing internet access. Bandwidth upgrade is not an option thus i have to do bandwidth shaping on our linux router. The question is how do set the squid configs to allow certain IP's range a certain percentage bandwidtheg 60% and furthe divide the rest. Alternatively how can allow certain IPs to have higher bandwidth access.

Well everything was ALOT louder on Windows, and I was wondering if there was a way to increase the maximum volume. I have to turn the volume almost all the way up to watch a movie. On Windows 1/4 volume was plenty. I searched, but alot of the answers I saw were that it was hardware limitations, which cant be the case, since it was a ton louder on Windows

My laptop is an acer 5678zg i think its called. I previously had 32 bit ubuntu and 64 bit now, same issueWhen I boot up ubuntu, my volume is sat at maximum which is really annoying since I have the sound through hdmi pass through via onkyo receiver and loudspeakers. Even when I turn volume down, the volume meter is not at top, but at where it was last time, but the volume is still at top and decreases to whatever volume I had at last time at first click on volume down.
View 9 Replies View RelatedIn the last week or so, I've frequently been running out of X server client connection slots and getting "Maximum number of clients reached" errors. For example, I'm getting it right now and I'm running 3 pterms, Chrome, and Thunderbird; I've even killed my panel. 'xwininfo -root -children' produces what seems to be an absurd number of X clients (150-ish, when it's able to make a connection), even immediately after Gnome/Xfce startup.
It doesn't take long. A day at most. I've had this system up and running for months, and this just started happening. I did install some X development libraries (x11proto-core-dev, libmotif-dev, x11proto-print-dev, and x11proto-xext-dev plus their dependencies) about two weeks ago, but this problem has not been happening that long. I've installed other packages, but nothing that would seem to have any relation to this problem. I've logged out and in, rebooted, and changed from Gnome to Xfce, and none of the changes helped.
I have a 30" apple cinema display. The monitor handles up to 2560 x 1600 pixels which is the optimum resolution for this monitor. I found out that most apple monitors have nvidia graphic card.The monitor is hooked up to a motherboard Intel BOXDG45FC. This motherboard has Onboard Video Chipset Intel GMA 4500. However, using KDE interface I dont get beyond 1280x800 resolution for the monitor.How can I get the maximum resolution for the monitor?

1. What tuning can I do to the kernel on a Ubuntu Lucid Desktop to achieve maximum IO to dd/cp/rsync/whatever those medias to hd?
2. What's the best scenario regarding HD/DVD drive connections to mainboard regarding IO/throughput?
The intention is to insert 4 medias at a time and copy them all in parallel to a local hard disk.

Here's what I've done so far:
I've enabled jumbo frames on the bond: ifconfig bond0 mtu 9000

Tweaked hdparm:
I haven't enabled jumbo frames on the switch but I'm almost sure that won't help me much after trying all this.

Ubuntu 8.04 used to detect my display resolutions fine, but this version is unable to detect my max. resolution and I get lock-ups when I use the live disk without the "nomodeset" option.

View 9 Replies View RelatedI just installed maverick on my son's netbook, and so far we like the new unity interface. The main issue is that there seems to be a maximum number of apps that can be listed under any particular category in the applications browser. So for instance when he goes to his "Games" category, it only lists applications up through S (he has a lot of games installed).
So far I haven't found a settings panel for unity. There has to be a way to bump up the maximum.

View 5 Replies View RelatedI have an AMD Athlon Regor 2.8 Ghz Dual Core CPU. About a month ago I overclocked the bad boy to 3.36 Ghz, on stock voltage. Since I have an AMD chip, I have the Cool and Quiet feature. With CnQ on, it never shows more than 2.8 Ghz (my stock speed), even on Full Load. However, with it off, it shows the correct 3360 Mhz all the time. I would like to keep CnQ, as well as my overclock. I've read in forums that it's okay to do that, that CnQ will automatically clock up to overclock when needed. But for me, with CnQ on, it only hits 2.8. Nothing more. Is this an Ubuntu problem? Is there a setting where I can change the maximum allowed speed of my CPU?

View 10 Replies View RelatedJust got an HP dv6-2150 laptop. Dual boot with Windows 7 and 9.04 (9.10 will not work but that's a different story). The screen resolution is too low and is set at the highest option available (1024x768 which is a 4:3 aspect ratio). The HP uses the new Intel i3-330m chipset with on-board Intel HD graphics. The system is capable of 1366x768 resolution (16:9) - so how do I get it there? xorg.conf looks real generic - nothing specific to Intel.

View 4 Replies View RelatedI'm running nginx for static files and as a proxy server for a comet IM server on ubuntu Jaunty. On high load I'm hitting a limit of 1024 file descriptors. I've tried increasing this limit but still can't pass 1024. Does "more /proc/sys/fs/file-nr" gives me the global count of used file descriptors? Why do I see a maximum of 1024 open file descriptors in /proc/sys/fs/file-nr if this is the global count for the machine and each user should have at least 1024 allowed file descriptors by default? Is there a way to increase the limit while the server is running?
Some relevant info on my server:
sudo more /proc/sys/fs/file-nr
1024038001
sudo sysctl fs.file-max
fs.file-max = 38001
sudo nano /etc/security/limits.conf
...
* hard nofile 30000
* soft nofile 30000

worker_rlimit_nofile 10240;
