• Installing Linux on an Asus p8z68-m PRO Motherboard

  - by Holland

  Here is a challenge: how is this done? I've tried disabling the ASM1061 controller in the Onboard Devices section, using Wubi, booting from USB (as I don't have a DVD drive, yet), and even booting from RAID/IDE (with AHCI as the default) to do this. Still, no dice. Google shows up virtually nothing related about Linux and this mobo, apart from a people just saying "disable ASMedia" (which, I assume is the ASM1061 controller, as that's all I see - apart from the USB 3.0, which I disabled already) and it hasn't really helped much. Thus, what is wrong here? Edit My problem is that I cannot boot Linux via USB or a simple Windows installer such as Wubi (for Ubuntu). I wind up getting error messages along the lines of write cache failed, along with many other cryptic error messages similar to the following: [ 1400.351374] sd 4:0:0:0: [sdb] Test WP failed, assume Write Enabled [ 1400.353433] sd 4:0:0:0: [sdb] Asking for cache data failed [ 1400.356601] sd 4:0:0:0: [sdb] Assuming drive cache: write through This seems to be common for Asus P8Z68-M Pro motherboards, with the only notable solution being to "disable ASMedia", which, as I said before, I'm guessing is the ASM1061 controller on the motherboard. Despite already disabling this, I have tried this with both Fedora and Ubuntu without any success. I need to know what I can do about this; has anyone ran into something similar or heard about this issue before? I know these motherboards are relatively new...

• Cisco Catalyst 3750 connected to Cisco ASA 5505 and dropping packets

  - by Bo102010

  (Cross posted from Super User per suggestion there) At the office, I have inherited a network that I am still trying to fully comprehend. I have a problem today with a new connection between: A port on a Cisco Catalyst 3750 [WS-C3750G-48TS-S running C3750-IPSERVICESK9-M version 12.2(53)SE1] A port on a Cisco ASA 5505 [ASA Software version 8.3(2)] The 3750 is home to a Vlan that has a few ports assigned to it. interface Vlan3 description Internal network (172.18.160.0/24) ip address 172.18.160.1 255.255.255.0 I have a host (outside of my control) that needs to be in this VLAN (i.e it must have an address 172.18.160.something/24) that also needs to access the Internet. To accomplish this, I ran a link from the Catalyst (Gi1/0/13) to the ASA (Ethernet 0/5). I configured the Catalyst port like so: interface GigabitEthernet1/0/13 description To ASA, 172.18.160.69 switchport access vlan 3 switchport mode access speed 100 duplex full I configured the ASA like so: interface Vlan1 nameif inside security-level 100 ip address 172.18.160.69 255.255.255.0 interface Ethernet0/5 speed 100 duplex full Then I plugged the host into Ethernet 0/4 on the ASA and instructed its owner to make its default gateway 172.18.160.69. I made a NAT rule in the ASA and set up some rules, and it's able to access the Internet without issue. However, I noticed that the Catalyst reports a ton of packets being dropped toward the ASA. Catalyst3750#show interfaces GigabitEthernet 1/0/13 | include counters|drops Last clearing of "show interface" counters 00:28:13 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 136909347 This is a huge number of drops, since there's not much traffic on this VLAN at all. I tried these things: Make sure speed and duplex agree on both sides (100 Mbps / Full) Set no cdp enable on the Catalyst Gi10/13 Set no keepalive on the Catalyst Gi10/13 Checked for excessive CPU usage on both Checked for excessive traffic on both Am I missing something? Any help would be appreciated.

• Improving abysmal 802.11n wireless network

  - by concept

  I am in desperate need of help to improve the abysmal performance of my 802.11n wireless network. At best I get 30Mbs (this is an internet download) from a technology that boasts 300Mbs, even worse is the LAN where to date best i have ever gotten is 1Mbs. It is literally quicker to copy the file to a USB and walk it to the other computer.

• Are there any wireless webcams/cameras that Windows will recognize as a capture device?

  - by Keithius

  I'd like to have a webcam in a different room from my computer, and the distance means USB is out of the question. I know there are many wireless cameras, but what I can't seem to find out is if any of them would be recognized by Windows as a capture device (just like a locally connected USB webcam). Most of the wireless cameras I can find (e.g., D-Link DCS920; Cisco-Linksys WVC54GCA, etc.) can all stream video directly from the camera itself, which is fine if you're using the camera as a "security" camera (for private use only), but not for other uses (say, sending the video to an online video streaming service, e.g., Ustream). It seems like this should be possible; after all, wireless (WiFi) printers with scanners are recognized by Windows. Are there any wireless (WiFi) cameras out there that would be recognized by Windows as a capture device in the same way as a USB webcam would? Alternatively, a camera that's not wireless (e.g., connects via Ethernet) would do the trick too - but I imagine if anyone is going to make a remote camera like this, they'd go the extra step and make it wireless, too.

• Is dual-channel RAM operation independent for each bank?

  - by user553702

  For dual-channel usage of DDR3 SDRAM, what happens if one bank has DIMMs in both channels but the other bank has only one DIMM in one channel? Will the bank with the paired DIMMs operate at the dual-channel rate while the bank with the unpaired DIMM operates at the single-channel rate? Or does having a bank with an unpaired DIMM force all of the RAM to operate as single-channel? For example, if I initially have only one bank populated with paired 4GB sticks operating as dual-channel, what happens if I then add a single 8GB stick to the other channel leaving the last DIMM slot empty? Will this stop the 4GB sticks from being dual-channel? In addition, what happens if each bank has DIMMs of different clock speeds? Does each dual-channel bank operate at an independent speed, or does all of the RAM operate at the slowest DIMM's speed? For example, in the above scenario, what would happen if the 8GB stick I added is slower than the original 4GB sticks in the other bank? Will the (paired) 4GB sticks then operate at a slower speed than before?

• Disk IO slow on ESXi, even slower on a VM (freeNAS + iSCSI)

  - by varesa

  I have a server with ESXi 5 and iSCSI attached network storage(4x1Tb Raid-Z on freenas 8.0.4). Those two machines are connected to each other with Gigabit ethernet. The raid-z volume is divided into three parts: two zvols, shared with iscsi, and one directly on top of zfs, shared with nfs and similar. I ssh'd into the freeNAS box, and did some testing on the disks. I used ddto test the third part of the disks (straight on top of ZFS). I copied a 4GB (2x the amount of RAM) block from /dev/zero to the disk, and the speed was 80MB/s. Other of the iSCSI shared zvols is a datastore for the ESXi. I did similar test with time dd .. there. Since the dd there did not give the speed, I divided the amount of data transfered by the time show by time. The result was around 30-40 MB/s. Thats about half of the speed from the freeNAS host! Then I tested the IO on a VM running on the same ESXi host. The VM was a light CentOS 6.0 machine, which was not really doing anything else at that time. There were no other VMs running on the server at the time, and the other two "parts" of the disk array were not used. A similar dd test gave me result of about 15-20 MB/s. That is again about half of the result on a lower level! Of course the is some overhead in raid-z - zfs - zvolume - iSCSI - VMFS - VM, but I don't expect it to be that big. I belive there must be something wrong in my system. I have heard about bad performance of freeNAS's iSCSI, is that it? I have not managed to get any other "big" SAN OS to run on the box (NexentaSTOR, openfiler). Can you see any obvious problems with my setup?

• MySQL Server Is Slow

  - by user2853965746

  I have two MySQL servers and one was just recently setup. The one I just recently setup is a bit slower than my older one, which kind of bothers me because I don't want my clients to be upset with the speed difference when I launch the new one. The older server runs on Ubuntu (~13.04 I believe) and the new one is on Debian 6. Both servers are 2GB ram, but my newer server is has an SSD, so I thought it might be the same speed if not faster. Anyway, the speed difference isn't too much (both are still under a second, but still noticeable). Whenever I select 50 rows from the user table on my older server (SELECT * FROM users LIMIT 50), I get the results in 0.003 s. There is 100,000+ accounts in that table. Whenever running the same command on the same table with only six dev accounts, it takes 0.069 s. It may not seem like a lot, but it's noticeable when you're used to a fast response. I added skip-name-resolve to the config and it didn't seem to help. Basically I'm asking if anyone knows what can cause a MySQL server to be slow in Debian 6? Should I just drop it and switch to Ubuntu like the older server (I don't think the OS is the problem, but you never know)? The older server is under a lot of use too, it's used a lot for web api's on my website. A lot of connections and stuff, and it still remains fast.

• Can I have 2Gbit over 1Gbit Nics

  - by Daniel

  So this really baffles me. Apparently because 1Gbit can transmit data in both directions simultaneously it should be possible to get 2Gbit of data transfer on a single NIC (1Gbit flow seend and 1Gbit receive). People claim that because 1Gbit is full-duplex (almost always) it is exactly 2Gbit in total. My intuition and electrical background tells me that something is not right here 4 twisted pairs 250Mbit capacity each gives 1Gbit. Unless it is really possible to transfer data in both directions simultaneously. I did a test with iperf. Ubuntu server 12.04 <-- MacBook Pro. Both with decent CPU speed. Tested speed of connection individually and on Mac I can see 112MB/s regardless which direction data is going. On Ubuntu with vnstat and ifstat I got 970Mbit speeds. Now, launching iperf in server mode on both machines at the same time and sending data using 2 iperf clients shows that I'm for example on Ubuntu box sending at 600Mbit, and receiving 350Mbit. which adds up to pretty much 1Gbit link. So to me there is no magical 2Gbit. Can someone confirm that or tell why I'm wrong? Another thing that confuses me i the fact that e.g. 24-port switch has for example: Throughput»up»to:»50.6Mpps Switching»capacity:»68Gbps Switch»fabric»speed:»88Gbps Which would suggest thay can handle 2GBit per port.

• Any way to move Office Starter To-Go to a non-flash drive?

  - by Scott Bussinger

  Microsoft's Office Starter edition has an interesting option to create a portable version on a USB flash drive using the "Microsoft Office Starter To-Go Device Manager". This creates a portable version of the Word and Excel starter editions (limited versions of the normal applications that include ads). This would be great for use in Virtual Machines since it requires no registration and has a perpetual license. But I want to copy the files off of the flash drive and just store them in the VHD. The problem is that it appears when you try to run the office.exe executable from anywhere but the USB drive you get the error "Microsoft Office Starter To-Go cannot be launched because it is installed on an unsupported device." Any ideas what it is objecting to and is there a legal workaround for this? A limited but legal and portable version of Word and Excel is a great idea. But tying it specifically to a USB flash drive seems a bit odd. They don't seem to care how many of those flash drives you create so it's not clear what the restrictions are about.

• Static noise in headphones

  - by John Murdoch

  I have a Asus P6T based system. I was using the on-board sound (plugging in Logitech X-230 2.1 analog speakers in the green "front speakers" 3.5mm analog output, then plugging in my headphones in that). I was quite happy with the sound quality (didn't hear any static noise if volume was turned down to my normal listening level). Then about a week ago I started having terrible static noise from the left channel, and no normal audio on that left channel. Right channel had more static noise than usual but did have a bit of sound. I tried using the AC'97 in front of my case but that seemed to have no signal. I decided my on-board sound card has gone bad and bought an internal sound card to replace it (Startech 7.1Ch PCI). This fixed the "no sound from left channel problem", but I had much more audible static noise. I decided the card was low quality and/or it had interference from all the other things happening inside the computer case, and bought a Sweex SC016 external USB sound card. But even with that I have static noise in headphones. Positioning the USB sound card differently doesn't seem to help. Trying the other analog outputs (e.g., surround) doesn't help. The static noise in all cases is proportional to the volume. I have tried different headphones, but the situation is situation though perhaps the flavour of the static noise changes slightly. So what are my options? a) Get another, more expensive, external USB sound card hoping the quality will improve? b) Get another, more expensive, internal sound card (PCIe 1x perhaps) hoping the quality will improve? c) Get a dedicated DAC box? d) Get some Hi-Fi earphones? Suggestions? tl;dr - Two different sound cards both still have static noise in headphones.

• Linux Mounting Problem

  - by Sam

  I have an Iomega Network Attached Storage device on my Windows network. I am trying to use a clonezilla live USB flash drive to backup my netbook to my Iomega Network Attached Storage device. The clonezilla USB flash drive runs linux. I'm having trouble getting the Network Attached Storage unit to mount using the following command: mount -t cifs -o username="myUsername" //192.168.1.100/backup /home/partimg The response from linux is: [134.730738] CIFS VFS: cifs_mount failed w/return code = -6 retrying with upper case share name [134.788461] CIFS VFS: cifs_mount failed w/return code = -6 mount error(6): No such device or address Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I also tried adding the following to my username: username="myUsername,domain=workgroup" but that did not change the error. I am able to ping the network attached storage unit from linux on my netbook. I also booted from a Slax Live USB Flash Drive and Slax auto-mounted my network attached storage unit via Samba. Unfortunately, I don't believe that I can run clonezilla from inside the Slax installation. Does anyone have any insight about what is wrong with my mount statement? Or is there something peculiar about Iomega drives which makes this impossible?

• Slow network file transfer (under 20KB/s) on newly built x64 Win7

  - by Mangoshake

  I am getting <20KB/s for local network file transfer. If I transfer a very small file (less than 100KB) it would start quickly then slow down to <20KB/s. all subsequently network file transfer would be slow, a reboot is needed to reset this. If I transfer a large file it would be stuck on calculating for a long time and then begin with <20KB/s immediately. This is a newly built desktop running Windows 7 x64 SP1. Realtek gigabit LAN from the motherboard (ASRock Extreme3 gen3). Problematic speed is observed on the private LAN, both through ethernet and WiFi. The Router is D-Link DIR-655. Remote Differential Compression is off. Drivers are up-to-date from ASRock's website. I have tested network file transfer to and from another Windows 7 laptop and a MacBook Pro, so I am fairly certain it is the desktop's problem. The slow speed only happens with one direction also, outbound from the desktop, regardless of whether I initiate the file transfer action from the origin or the destination. Inbound network file transfer and internet speeds are fine, so I don't think this is a hardware issue. I am getting 74.8MB/s internet upload speed from speedtest.net (http://www.speedtest.net/result/1852752479.png). Inbound network file transfer I can get around 10-15MB/s. I am hoping this community has some insight for me to troubleshoot this. I don't see anything obviously related from the Event Viewer, and beyond that I just don't know where else to look. Any suggestions are greatly appreciated, thank you in advance.

• Very slow connection to xserve via afp or smb

  - by Mhoffman13

  Help. File transfer and connection speed to our Xserve are painfully slow from newly purchased iMacs. The Xserve is only used as a file server, its running 10.4.11. The problem seems to be only happening on brand new iMacs running 10.6.3. When connected either over afp or smb copying files is many times slower than usual. Other machines on the network running either 10.4 or 10.5 have a normal connection speed. To try to rule out OS incompatibility I connected the new iMac running 10.6 to another computer running 10.4 over the network. The file transfer speed was fast as normal. So it seems the problems lies with the X serve (maybe). The afp logs either access or error don't show anything unusual. One thing that did look different was when the imac was connected to the Xserve the user had its id listed as its IP address. The other machines connected, had the id of broadcasthost. I also noticed that when connected from the new iMac I can only see one of the mirrors. When any other computer connects both mirrors are shown. Tried a restart of the Xserve but the problem persists. Thanks in advance for any advice

• Can I have damaged a CPU ?

  - by Pascal

  Hey guys, This is a question I asked on Anantech forums, but I just discovered this community and think this question would fit right in. Here goes: I built a PC around a Q9550 1 1/2 years ago (MoBo is an Asus P5Q deluxe). Specs give 2.83GHz, OC'ed it to 3.40 GHZ without any problem (or so I thought) till 2 months ago. Cooling is provided by stock Intel Fan... 2 Months ago, I began to see random crashes, bios saying CPU overheat error... PC would reboot at OC'ed speed without any problem. Since last saturday and a few more crashes, PC won't reboot at 3.40 GHz, and even at stock speed (2.83 GHz), I got core temperatures of (60 C idle, 95 C under load) on the first two cores. This is the 4 core temperatures I am talking about, not the T-CPU which obvioulsy is lower. Fan is running at a steady 2000 RPM. Questions for you : 1. Is 2000 RPM the normal speed of the Intel fan or is my fan somehow broken (which could explain the overheating). In this case, any recommendation for a good fan for OCing ? 2. Hypothesis I fear is the right one: can the CPU have been slowly damaged over time by this OCing, meaning there is nothing much to do except waiting for it to die ? (As a side note, I am surprised that the 9550 is still around 300 $CDN here... Thought it would have been cheaper with all those i3/i5/i7 around). Any help or advice would be more than welcome...

• Convert a cassette tape recording to digital format

  - by Electric Automation

  Has anyone been successful with transferring audio cassette tape recordings to a digital format? I would like to preserve old cassette tape recordings of my grandparents to some digital format: MP3, WAV, etc... The quality of the tapes are mediocre. I think I can handle the quality restoration but getting the audio from tape to digital is my question. Below is a list of the hardware that I can work with: Cassette Deck: I have a Technics stereo cassette deck model RS-B12. It has separate left and right IN and OUT RCA type jacks on the back. In the front it has a headphone phono jack, plus left and right mic input phono jacks. On the computer side: -I have a Windows Vista PC with no additional software other than what came with the machine from Costco. No sound editing software that I can see. There is no sound card on the PC. On the front panel there is a mini-phono mic input jack and there are several different types of in/out mini-phono jacks on the back. In addition, USB and Firewire. I also have access to a new (2009) iMac with a mini-phono input jack for a powered mic or other audio source and GarageBand that has come with the computer. In addition, USB and Firewire. What are my options for getting these cassette recordings into a digital format? Whats the best format? What sort of wires would I need and will I want to utilize the USB or Firewire or can I simply use the audio inputs on the PC (or Mac) to receive the audio stream?

• computer build for extreme tabbed browsing

  - by David Berger

  I'm interested in building or buying a task-specific computer for my brother. His requirements are ridiculously simple: the machine has to be able to wait in hundreds of web-based virtual waiting rooms at once and not crash. To be competitive, he needs to be able to enter the waiting rooms an dauto-refresh them faster. My question is, what priority do I give the different specs? My initial surmise is this: Connection speed (nothing to do with my build, but I kind of think this will be more beneficial than anything I build for him) Memory size -- I don't usually see firefox taking up more than a gig, even when heavily tabbed, but I think one gig for the operating system and two gigs for the browser are necessary. Processor speed -- I think the processor will affect performance, but even something out of date will do what he needs Memory speed/RAM bus -- I doubt this will matter much, but it seems just on this side of irrelevant. Everything else is a non-issue for him. Does this seem to stack up correctly? Also, since he's looking to stay on the cheaper side, and I might end up recommending a refurb to him, is there anything particularly egregious that Vista would do if it came pre-installed? If I build it myself, I'll give him linux, but if I have it shipped to him, I'm not sure I could walk him through the install process for linux, but I probably could walk him through the process to upgrade to Windows 7, if it were somehow worth it.

• Hard drive spark, can it be recovered?

  - by user163558

  Alright, so I was going to install Source Film Maker but I didn't have any space, so I decided to connect an HDD via an USB converter(image below). I shut down the machine, turned the PSU off, and connected via a Molex connector & the USB converter. I turned back on the PSU, no sparks or anything, everything normal, but when I turned on the machine, I heard some sizzing(lol?) and sparks flying and a little flame, but the PC was running fine. I pressed the power button instead pulling out the plug (I panicked) so it continued to short circuit for about 10 seconds. There's a very little part on the HDD that become ash, it's near the Molex connector and the circuit is a little black as well. I'm afraid that I will damage the HDD more so I didn't hook up the HDD after all. Do you think it's the PSU(came default with Cooler Master Elite 430, 500W) or it's the HDD(Samsung SP1203N)? P.S: I've attached the HDD same way before(like 3 months ago), and it worked. HDD burn: USB connector: Sorry for the bad image quality, taken with my phone.

• Convert a cassette tape recording to digital format

  - by Optimal Solutions

  Has anyone been successful with transferring audio cassette tape recordings to a digital format? I would like to preserve old cassette tape recordings of my grandparents to some digital format: MP3, WAV, etc... The quality of the tapes are mediocre. I think I can handle the quality restoration but getting the audio from tape to digital is my question. Below is a list of the hardware that I can work with: Cassette Deck: I have a Technics stereo cassette deck model RS-B12. It has separate left and right IN and OUT RCA type jacks on the back. In the front it has a headphone phono jack, plus left and right mic input phono jacks. On the computer side: -I have a Windows Vista PC with no additional software other than what came with the machine from Costco. No sound editing software that I can see. There is no sound card on the PC. On the front panel there is a mini-phono mic input jack and there are several different types of in/out mini-phono jacks on the back. In addition, USB and Firewire. I also have access to a new (2009) iMac with a mini-phono input jack for a powered mic or other audio source and GarageBand that has come with the computer. In addition, USB and Firewire. What are my options for getting these cassette recordings into a digital format? Whats the best format? What sort of wires would I need and will I want to utilize the USB or Firewire or can I simply use the audio inputs on the PC (or Mac) to receive the audio stream?

• Netbook (Samsung N220) on Ubuntu 10.04 slows down WiFi for other computers

  - by Joachim

  I encountered a really odd problem with my new netbook. I am running Ubuntu 10.04 on a Samsung N220 Mito. So far everything worked fine. Now I tried the machine for the first time in our work group where we have a wifi (with internet access) for all laptops. The wifi is controlled by a computer running Suse 9.3 which provides a DHCP server and imposes a firewall. At the moment there is only a macbook in the wifi, where no problems with the internet or wifi connection are encountered. Now coming to my actual problem: In addition to the macbook i connect the Samsung N220 to the Wifi. Problem: My download speed is for some reason limited to 70KB/s max. This is neither a limitation of the server/website i browse on, nor a configuration of the netbook: at home i have 500KB/s download speeds. Furthermore, it is not a default limitation for "untrusted" or "new machines" in the wifi, as for instance other new laptops get full speed internet with our wifi. Problem: Once the Samsung N220 is generating traffic in the wifi, the wifi is slowed down dramatically for all other machines: I run a ping to the router from the macbook. The ping times with the N220 ideling are 2-6ms. When I start downloading or browsing in the web with the N220 the ping speed drops to 800ms. Vice versa, when the macbook is generating the traffic the ping of the N220 to the rooter stays constant at around 2-6ms. So clearly, it is some problem originating from my netbook or maybe its treatment in the wifi. Thanks for any help

• What can I do to prevent system power downs?

  - by Joe King

  Yesterday I was given my brother's old laptop - core i7, 2.67GHz, 8GB RAM, 128GB SSD, Win7 64 bit. It's a Sony Vaio Z11. Approx 18 months old. When running something computationally intensive, the fan starts up and after about 30 secs it just powers itself down with no warning. I guess it is overheating. There is nothing in the event logs to suggest what is causing it - the only thing I see is "the last system shutdown was unexpected" or something similar. This is a problem for me because I use a lot of number crunching apps, which pretty much makes it useless to me. I would like to know if there is anything I can do, other than the obvious things I've done already - open up and clean out dust, re-install the OS. According to my brother, this problem started about 6 months ago when it was already outside warranty. If it's just used for simple things - web browsing, word processing etc, the problem does not occur. Any ideas for what I can do to fix this ? Update: I found that the laptop has 2 hardware settings for graphics: Speed and Stamina - the Speed setting seems to use an nvidia GEforce GT 330M, while the Stamina setting uses an Intel chipset. With the setting on Speed, I can hear the fan the whole time, and the system powers down after a short while (5-10 mins) even just doing basic tasks (browsing this site for example), but doesn't shut down if I just leave it switched on. In this mode it also sometimes just freezes the screen and I have to power off myself. However on Stamina setting it only powers down when doing number crunching and never freezes the screen.

• Traffic shaping on Linux with HTB: weird results

  - by DADGAD

  I'm trying to have some simple bandwidth throttling set up on a Linux server and I'm running into what seems to be very weird stuff despite a seemingly trivial config. I want to shape traffic coming to a specific client IP (10.41.240.240) to a hard maximum of 75Kbit/s. Here's how I set up the shaping: # tc qdisc add dev eth1 root handle 1: htb default 1 r2q 1 # tc class add dev eth1 parent 1: classid 1:1 htb rate 75Kbit # tc class add dev eth1 parent 1:1 classid 1:10 htb rate 75kbit # tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip dst 10.41.240.240 flowid 1:10 To test, I start a file download over HTTP from the said client machine and measure the resulting speed by looking at Kb/s in Firefox. Now, the behaviour is rather puzzling: the DL starts at about 10Kbyte/s and proceeds to pick up speed until it stabilizes at about 75Kbytes/s (Kilobytes, not Kilobits as configured!). Then, If I start several parallel downloads of that very same file, each download stabilizes at about 45Kbytes/s; the combined speed of those downloads thus greatly exceeds the configured maximum. Here's what I get when probing tc for debug info [root@kup-gw-02 /]# tc -s qdisc show dev eth1 qdisc htb 1: r2q 1 default 1 direct_packets_stat 1 Sent 17475717 bytes 1334 pkt (dropped 0, overlimits 2782 requeues 0) rate 0bit 0pps backlog 0b 12p requeues 0 [root@kup-gw-02 /]# tc -s class show dev eth1 class htb 1:1 root rate 75000bit ceil 75000bit burst 1608b cburst 1608b Sent 14369397 bytes 1124 pkt (dropped 0, overlimits 0 requeues 0) rate 577896bit 5pps backlog 0b 0p requeues 0 lended: 1 borrowed: 0 giants: 1938 tokens: -205561 ctokens: -205561 class htb 1:10 parent 1:1 prio 0 **rate 75000bit ceil 75000bit** burst 1608b cburst 1608b Sent 14529077 bytes 1134 pkt (dropped 0, overlimits 0 requeues 0) **rate 589888bit** 5pps backlog 0b 11p requeues 0 lended: 1123 borrowed: 0 giants: 1938 tokens: -205561 ctokens: -205561 What I can't for the life of me understand is this: how come I get a "rate 589888bit 5pps" with a config of "rate 75000bit ceil 75000bit"? Why does the effective rate get so much higher than the configured rate? What am I doing wrong? Why is it behaving the way it is? Please help, I'm stumped. Thanks guys.

• Windows XP Boot Issue - Diagnosing A Hard Drive Failure

  - by duffymo

  My five-year-old HP desktop running Windows XP SP3 wouldn't boot from the hard drive yesterday afternoon. I would see the boot sequence begin, then nothing but a black screen. Fortunately, I had just done an Acronis backup to my external drive in the morning, and I have a bootable USB key. I put the USB key into the drive, powered up the machine, and put the USB key first in line in the boot sequence. Voila! My machine came alive. But now I'm confused as to what the problem is and what to do next. I assumed that my hard drive was toast. But now that the machine is alive I can see files on my C: drive that have changes I made just yesterday. Clearly the drive is not dead. Here are my questions: What could explain my inability to boot from the hard drive? What would a remedy be? What's my best course of action? Should I replace the hard drive with a new one? If I replace the hard drive, do I reinstall the OS and apply the backup I did yesterday? If I decide that re-installing Windows XP makes no sense, how do I get back the Acronis backup that I did yesterday? I don't want to lose that. UPDATE: I just learned one more key fact. I'm having some work done on my house. I neglected to shut my machine down before the contractor came. My wife said he shut down the power to do some work on a circuit and then powered the house back up. I have a surge protector, but is it possible that cycling the power did some damage?

• My PC is powercycling, what's going wrong?

  - by Renai

  So here is my sorry story of woe. My PC has been functioning normally for some time. Last week I bought a cheapish powered USB hub and plugged it into my home PC, which runs Windows 7. This weekend I plugged that hub into my home PC. At some stage I hibernated the PC. Then later on I plugged my Kobo eReader into the hub to charge. Later on I started the PC up. Only thing is, it now won’t start up. It just powercycles on for a second and a half with the fans at full, then powercycles off. Then back on for two seconds, then back off. There’s no display at all and it won’t get to the BIOS screen. It looks like anything USB is not functioning — the keyboard and mouse are not lighting up etc. I’ve taken out the BIOS battery and reseated the RAM, reseated the graphics card and so on, but my suspicion is that I have blown the USB section of the motherboard somehow. Suggestions? All else failing, where is the best place to take this machine in Sydney to get evaluated? It’s a fairly powerful beast, all up has cost me about $2500 over the years, including upgrades and a recent new graphics card, so can’t just start from scratch.

• SATA Driver for Acer Aspire One D257

  - by Robert Niestroj

  i have a Acer Aspire One D257. In this netbook the hard disk is defect so i bought a new one. Now i want to reinstall Windows 7. Im using an external DVD Drive plugged into USB. The Windows 7 DVD is staring, Win7 setup is starting and when it comes to Hard Drive options it says that no drive was detected and i should try search for drivers. It shows me this window: Screenshot from web Now i cant find the right drivers for this netbook to continue with the installation. The laptop has the newest BIOS - 1.15, it is reset to factory default settings except that i enabled the Boot Menu prompt with F12. From the Acer Support Website i've downloaded the SATA AHCI Driver and the Chipset Driver. I unpacked both to a USB flashdrive in seperate folders. When i select the SATA AHCI Driver it does not find any drivers. When i uncheck the checkbox "Hide drivers that are not compatible with hardware on this computer" it shows one driver: Acer HWID (path_to\1.inf). When i continue with this driver i got an error message that says something like: No new devices found. Check if the driver files are on the installation disk. When i show him the Chipset Driver it sees a lot more driver. When i uncheck the checkbox "Hide drivers that are not compatible with hardware on this computer" it show some drivers: Intel N10 Family DMI Bridge Intel N10/ICH7 Family PCI Express Root Port Intel N10/ICH7 SMBUS Controller Intel N10/ICH7 Family USB Universal Host Controller Intel N10/ICH7 Family USB2 Enhanced Host Controller Intel N10/ICH7 Family Interface LPC Controller When i uncheck this checkbox i get a lot more drivers, and some SATA Drivers but the also do not work. I get the same error message as before. Can someone help me find a driver that should work or am i doing anything else wrong?
