• Program to see, which programs use the internet-connection?

  - by Martti Laine

  Hello Few days ago I opened my computer as I always do after school, and got pretty amazed about my 1.27kb/s download-speed. It has continued for few days already. We have a wireless network, which is used by 3 computers. Normally I've gotten 200kb/s (I think we have a 2mb-connection) but now it just suddenly slowed down. My friends have the same service-provider, but no problem. So, is there any kind of program, which would show me all the programs using connection and how much. It must be a program open which just takes all speed off. Any help is appreciated, Martti Laine

• Blank screen after GRUB (64 bit) - cannot install Ubuntu

  - by peGGi

  My laptop's specs: Lenovo IdeaPad Z570 Intel Core i5-2410M @ 2.3Ghz 6 Gb RAM DDR3 640 Gb ATAPI Hard-disk Drive @ 5,200 RPM NVIDIA GeForce G520M with Optimus switching technology Broadcom 802.11n Network Adapter REALTEK soundcard Windows 7 Home Premium 64-bit I downloaded Ubuntu Studio 11.04 and burned the iso image onto two different DVDs, using two different programs (one DVD is RW, the other is just R). I verified the hash MD5sum thing. I get as far as GRUB with the 4 options (install, advanced install, disk verification, system rescue) but no matter which one I select, I get a blank screen and nothing happens. The DVD drive spins down after about 30 seconds. Also just before the GRUB screen I get a message saying Error: "Prefix" is not set. I'm not sure if that's relevant. I have tried all the options using both DVDs. Same thing happens. I have changed the graphics setting in BIOS to UMA or Optimus, but still happens either way. I've tried booting with the wireless switch turned off, same thing happens. I downloaded 'vanilla' Ubuntu 64-bit and burned onto a CD, and the same thing happens. I have downloaded Ubuntu 32-bit and I am able to boot from the live CD (interestingly the wireless card won't work, but that's maybe another issue). I have searched extensively through these forums and other sites but I can't see anything that will help me. Is there something I'm missing? I'd really appreciate help on this. The laptop is less than 2 weeks old. I was so looking forward to getting Ubuntu Studio up and running. I've gone about as far as my technical abilities will allow.

• Building new GIS Workstation - is it worth upgrading to a workstation GPU?

  - by bsigrist

  We are currently building a machine from scratch to act as a GIS workstation. The primary software used is ESRI's ArcGIS and we are mainly working with vector data using raster data only for contextual background imagery. In the past I have built a GIS machine and used a consumer grade gaming GPU (Nvidia 9800GT) and found it to perform fine. However, I have always wondered if I would have been better off equipping it with a workstation GPU such as a Quadro series. Would a workstation GPU make a noticeable difference doing 2D GIS operations or should I save money on the build and equip it with another 9800GT?

• Not allowed to upload .HTML files to my own DNN Site: Is it normal?

  - by Jake M

  My Question: Our webhost provider wont make it so we can upload .html files to our DNN site trhough the DNN File Manager page. Is that normal, should I push them to allow me to do this? We have recently transferred our website to a Dot Net Nuke run website. We originally had our website on a Linux server with Python scripts handling the backend. Obviously we now have a Windows server running .NET with ASP .NET code on the backend. Our webhost is a local Australian company. And they are saying we cant upload any .html files to the main part of the server, ie, www.ourdomain.com/Portals/0/. They are saying that the only place I can upload .html files is via FTP to this folder *www.ourdomain.com/Portals/0/html_content* This is a major problem for me because I am trying to upload my own skin which means I need to upload a main.html file to www.ourdomain.com/Portals/0/skins/myskin/ but they wont let me?! I guess what I am asking is, is this normal practice, why would they not allow this? As an experienced web admin for Linux servers and as someone who is used to being able to do whatever I want on my OWN server this is someing that really pis$%s me off!

• How do I get Graphics drivers / bluetooth / card reader working on an Acer Aspire V3-571G?

  - by Adam

  A couple of days ago I bought an Acer Aspire V3-571G laptop without a system installed on it. The only thing that was there was Linux Linpus. I created a bootable CD with Ubuntu 12.04 64-bit - I read that my processor was 64 bit and that it might be a good configuration for my gear (I'm not especially fluent with all the computer stuff, still trying to learn) and replaced Linpus with Ubuntu. Everything seemed to work fine, but there're few exceptions to that which came pass my way. My bluetooth doesn't work. It seems to be switched on, but when I check my system settings the button is actually off, and I can't drag it 'perminently' to the 'on' position. Tried a couple of commands I found on the net, none of them helped and there was no word whatsoever in my BIOS settings about enabling bluetooth. My card reader has some serious problems with copying more than one file at a time. I tried to put some music on my phone through a MicroSD card adapter (because my bluetooth doesn't work) and it got stuck every single time I copied an album on it. I'm not sure if all my drivers were properly installed, so I checked in the terminal if it could tell me sth about my graphics. typed: sudo lshw -c display and what i got was: *-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:b2000000-b2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:2000(size=128) *-display description: VGA compatible controller product: Ivy Bridge Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:b3000000-b33fffff memory:c0000000-cfffffff ioport:3000(size=64) As I said I'm no expert and not english-speaking generally, but it doesn't seem to be right.

• Using TrueCrypt with File Replication on Windows Server

  - by neildeadman

  We have a few folders that are set to replicate to a DR file server off-site. One of these folders contains a file that is a TrueCrypt volume container. When this file is mounted in TrueCrypt, the file won't replicate (fair enough!). I'm looking at alternatives to improve this situation. One solution I currently have is to have a scheduled task to unmount the volume and then every morning as the volume is needed, have someone mount it. This is a pain slightly because the password is known by a few people (I'm not one and neither are my colleagues who would be performing the mounting operation) so we'd need to continually get them to come over and type it in. The other I had was to have one TrueCrypt container on each server and replicate the contents when they are mounted. I wasn't able to get TrueCrypt to see the mounted volume so I guess this is a no go. Any other solutions I have missed or a fix for the above?

• Unable to mount an LVM Hard-drive after upgrade

  - by Bruce Staples

  I imagine this is a basic gotcha ... but I can't see it. I have a system with 2(physical) harddrives. The boot system (/dev/sda) was running 10.04 & the second drive (/dev/sdb) was just a mounted filesystem. I did a clean load of Ubuntu 12.04 overwriting /dev/sda (not an upgrade) & now cannot mount the second drive. so I do not know what to enter it into the fstab ... I had expected to use: /dev/sdb /tera ext4 defaults 0 2 But even manual mounting fails (I also have tried various "-t" options on the off chance!) sudo mount -t ext4 /dev/sdb1 /tera mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Output from disk queries indicate that it is a Linux LVM & a healthy disk still. sudo lshw -C disk *-disk:0 description: ATA Disk product: WDC WD5000AACS-0 vendor: Western Digital physical id: 0 bus info: scsi@2:0.0.0 logical name: /dev/sda version: 01.0 serial: WD-WCASU1401098 size: 465GiB (500GB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 signature=00015a55 *-disk:1 description: ATA Disk product: WDC WD10EADS-00L vendor: Western Digital physical id: 1 bus info: scsi@3:0.0.0 logical name: /dev/sdb version: 01.0 serial: WD-WCAU47836304 size: 931GiB (1TB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 sudo fdisk -l Disk /dev/sda: 500.1 GB, 500106780160 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976771055 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00015a55 Device Boot Start End Blocks Id System /dev/sda1 * 2048 972580863 486289408 83 Linux /dev/sda2 972582910 976769023 2093057 5 Extended /dev/sda5 972582912 976769023 2093056 82 Linux swap / Solaris Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 1 1953525167 976762583+ 8e Linux LVM LVM doesn't appear to be an option for mount or fstab. ... and here's a Smart data Screenshot from Disk Utility.

• Disable CD eject button on Windows laptop

  - by Marc Gravell

  Most laptops have a CD eject that is very sensitive, and placed such that it regularly gets triggered when handling the laptop. This is in particular a problem (for clumsy-handed me) when picking up the laptop to stow in in a laptop bag; I've lost count of the number of times it has ejected just as I am lowering it into the case! I rarely use a CD, but I am wondering whether some crafty software hack (or other trick) might be possible to make it less vulnerable. Perhaps trying to fool it into thinking it is busy (but ideally without destroying my battery). Otherwise, I might as well bow to the inevitable and snap the darned thing off. I'm not making this brand-specific, as I've seen this problem on a range of both branded and re-badged laptops. I am, however, mainly interested in windows-friendly solutions.

• KeepLevelReg settings to eliminate sync prompts - errors occurred while Windows was synchronizing your data

  - by Detritus Maximus

  We have 2 XP pro VMs (Citrix) that both have problems with logout prompts appearing during logout. Users are closing the rdc before these appear: The Microsoft solution involves the creation of the KeepProgressLevel registry entry along with a value of 1 for "pause on errors." I have implemented this across the domain for this problem, yet these 2 VM's continue to have the prompts. Today, I experimented by changing the KeepProgressLevel option to 0. This is not one of the options given by MS, yet I stopped getting the prompts. Can anyone tell me what I've done by setting the value to 0? Have I basically turned off the feature as if the KeepProgressLevel entry is gone? If so, why no more prompts? I did notice during logoff that there is a red x and error message, yet no prompt.

• Disable discrete AMD GPU

  - by Smajl

  My notebook has two graphic cards and it suffers from severe overheating after installing Ubuntu (no problem with Windows 7 on the same machine). I figured out that the problem may be in the graphic card and I would like to disable the discrete one. I followed some tutorials on this topic (for example http://planetoss.com/articles/how-to-disable-the-discrete-amd-graphics-card-in-linux/). But the problem is, that after executing the commands, nothing really happens and both GPU are still running. Here is what I have done: smajl@smajl-mini:~$ sudo chown smajl /sys/kernel/debug/vgaswitcheroo/switchsmajl@smajl-mini:~$ echo IGD > /sys/kernel/debug/vgaswitcheroo/switch smajl@smajl-mini:~$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:DynPwr:0000:01:05.0 1:DIS-Audio: :Pwr:0000:02:00.1 2:DIS: :DynPwr:0000:02:00.0 smajl@smajl-mini:~$ echo OFF > /sys/kernel/debug/vgaswitcheroo/switch smajl@smajl-mini:~$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:DynPwr:0000:01:05.0 1:DIS-Audio: :Pwr:0000:02:00.1 2:DIS: :DynPwr:0000:02:00.0 What am I missing here? Also, more on the overheating topic: 1) Installed TLP 2) updated system 3) set power setting mode to "power save" ...and nothing helps Tried same thing with Linux Mint without success. Is there anything else to try if I manage to disable the second GPU and the problem preserves? Otherwise I would have to get back to win in order not to melt my laptop.. :-/

• Should I split my website into different servers

  - by Nyxynyx

  I have a website where a user uploads photos, the photos gets resized and thumbnailed, and stored on the server. At the same time, there are some INSERTS into a MySQL table regarding the photo uploaded (like description, user id etc). The site currently runs off a managed VPS, and I love the support it provides. However it is expensive to store the many small photos and the resizing and thumbnailing processes do cause spikes on the app performance. (Amazon S3 is pretty expensive, especially considering the costs for uploading many small files) Question: Will it be a good idea to move the image processing operations and image storage to another server which is an unmanaged dedicated server with a much lower cost/gb and keep the current VPS for its 24/7 support and hosting the webapp? Or should I move the entire site to the dedicated server?

• IBM PS/2 Keyboard with OS X 10.6 and PS2->USB Converter

  - by public static void

  Just got a new Mac Pro at work and as I can't stand the ZX Spectrum-esque 'dead flies' feel of the new Apple keyboards, I brought my trusty IBM SpaceSaver II to the office (with a USB/PS2 adapter) All seems generally to work ok - even the Trackpoint 'nipple' but periodically the modifier keys, notably the Ctrl and Windows keys seem to go into 'sticky' mode so that typing an 'S' brings up the save dialog, 'O' = open dialog etc. etc. Its generally fixed by switching windows and then returning back to the offending one, but this is really beginning to cheese me off. Can anyone suggest a fix?

• Google suddenly only indexes https and not http

  - by spender

  So all of a sudden, searches for our site "radiotuna" give out the result as an HTTPS link. https://www.google.com/?q=radiotuna#hl=en&safe=off&output=search&sclient=psy-ab&q=radiotuna&oq=radiotuna&gs_l=hp.12...0.0.0.3499.0.0.0.0.0.0.0.0..0.0.les%3B..0.0...1c.LnOvBvgDOBk&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.&fp=177c7ff705652ec3&biw=1366&bih=602 We only use https for the download of two specific files (these urls are resources used for autoupdate functionality of an app we distribute). All other parts of the site should be served over http. We wouldn't like to see any other traffic over https, nor any of our site links to appear in search engines as https. I'd like to address this issue. It seems that the following solutions are available: hand out an https specific robots.txt as such: User-agent: * Disallow: / and/or at app-level, 301 permanent redirect all requests (except the two above) to HTTP if they come in as HTTPS. My concern with the robots method is that, say (for some reason) google decided not to index http pages, disallowing https pages might mean that google has nothing left to index with disastrous consequences for our ranking. This means I'm inclined to go with a 301 redirect. Any thoughts?

• CentOS/Apache killing connections

  - by fin1te

  Getting a really strange error. Basically, whenever I browse to my server (http://[ip_address] or http://[hostname]), it doesn't load, and my active SSH connection drops out. I installed CentOS 5.5, and then httpd and PHP 5.3. No other applications where installed, so I can't imagine it's something else causing it. I also reinstalled CentOS 5.5 again, completely fresh, the only thing I did to it was yum install httpd, and it still caused this issue. I've changed nothing in the config or anything else. Driving me mad, has anyone heard of this? It's really frustrating since everytime I attempt to debug this issue, I get kicked off SSH and have to log back in. Theres nothing in the Apache error logs, and nothing in the access log recording my attempt. Also, the result from uname - Linux [hostname] 2.6.35.4-rscloud #8 SMP Mon Sep 20 15:54:33 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux Thank you

• How to troubleshoot a remote wmi query/access failure?

  - by Roman

  I'm using Powershell to query a remote computer in a domain for a wmi object, eg: "gwmi -computer test -class win32_bios". I get this error message: Value does not fall within the expected range Executing the query local under the same user works fine. It seems to happen on both windows 2003 and also 2008 systems. The user that runs the shell has admin rights on the local and remote server. I checked wmi and dcom permissions as far as I know how to do this, they seem to be the same on a server where it works, and another where it does not. I think it is not a network issue, all ports are open that are needed, and it also happens within the same subnet. When sniffing the traffic we see the following errors: RPC: c/o Alter Cont Resp: Call=0x2 Assoc Grp=0x4E4E Xmit=0x16D0 Recv=0x16D0 Warning: GssAPIMechanism is not found, either caused by not reassembled, conversation off or filtering.

• One of the partion on a usb harddisk cannot automount

  - by holmescn

  It is a very strange problem. My usb harddisk has four partitions, one is primary, the other three are logical (contained within an extended partition). When I plug in the disk, three of the partitions are mounted automatically except one--the first logical partition in the extended partition. Initially I thought it is the problem of system (at that time I used Mint). But after I change to Ubuntu 12.04, the problem wasn't solved. I don't want to add a rule in fstab, and I want to know what happened. The disk is fine, and the partition can be accessed in Windows and mounted manually. result of dmesg | tail: [100933.557649] usb 2-1.2: new high-speed USB device number 4 using ehci_hcd [100933.651891] scsi8 : usb-storage 2-1.2:1.0 [100934.649047] scsi 8:0:0:0: Direct-Access SAMSUNG PQ: 0 ANSI: 0 [100934.650963] sd 8:0:0:0: Attached scsi generic sg2 type 0 [100934.651342] sd 8:0:0:0: [sdb] 625142448 512-byte logical blocks: (320 GB/298 GiB) [100934.651977] sd 8:0:0:0: [sdb] Write Protect is off [100934.651989] sd 8:0:0:0: [sdb] Mode Sense: 03 00 00 00 [100934.652836] sd 8:0:0:0: [sdb] No Caching mode page present [100934.652848] sd 8:0:0:0: [sdb] Assuming drive cache: write through [100934.655354] sd 8:0:0:0: [sdb] No Caching mode page present [100934.655367] sd 8:0:0:0: [sdb] Assuming drive cache: write through [100934.734652] sdb: sdb1 sdb3 < sdb5 sdb6 sdb7 > [100934.737706] sd 8:0:0:0: [sdb] No Caching mode page present [100934.737725] sd 8:0:0:0: [sdb] Assuming drive cache: write through [100934.737731] sd 8:0:0:0: [sdb] Attached SCSI disk result of parted -l: Model: SAMSUNG (scsi) Disk /dev/sdb: 320GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 21.5GB 21.5GB primary ntfs 3 21.5GB 320GB 299GB extended lba 5 21.5GB 129GB 107GB logical ntfs 6 129GB 236GB 107GB logical ntfs 7 236GB 320GB 83.8GB logical ntfs

• How do I stop sound coming from my speakers with a faulty headphone socket?

  - by Andy

  On my laptop, I have a faulty headphone socket, so when I insert headphones into it, the speakers do not mute. I can confirm that this problem is caused by faulty hardware and not software as when I twist the headphone jack, the speakers come on and off according to the movements. On previous versions of Ubuntu, I worked around this problem by going into alsamixer and disabling "Auto-Mute Mode", and then going into the sound settings and choosing "Analog Headphones". However, on 12.04, no such option exists, rendering my headphones unusable with no way to work around the problem. I momentarily thought I had this problem fixed when I installed PulseAudio Volume Control from the Software Centre. I selected the Output Devices tab, and under "Built-in Audio Analogue Stereo" I selected "Headphones" for the port. However, this almost randomly seems to change back to "Speakers", despite me setting "Auto-Mute Mode" as disabled. Basically, I would like a way to permanently mute the speakers so only the headphones will play sound, without it losing my settings. It is ridiculous that such a simple setting has been taken away to "simplify" the user interface.

• Proper updating of GeoClipMaps

  - by thr

  I have been working on an implementation of gpu-based geo clip maps, but there is a section of the GPU Gems 2 article that i just can't seem to understand, specifically this paragraph and more precisely the bolded part: The choice of grid size n = 2k-1 has the further advantage that the finer level is never exactly centered with respect to its parent next-coarser level. In other words, it is always offset by 1 grid unit either left or right, as well as either top or bottom (see Figure 2-4), depending on the position of the viewpoint. In fact, it is necessary to allow a finer level to shift while its next-coarser level stays fixed, and therefore the finer level must sometimes be off-center with respect to the next-coarser level. An alternative choice of grid size, such as n = 2k-3, would provide the possibility for exact centering Let's take an example image from the article: My "understanding" of the way the clip maps were update was that you floor the position of the viewpoint to an int, and such get the center vertex point if this is not the same as the previous center point, you update the entire map. Now, this obviously is not the case - but what I am failing to understand is this: If you look at the image above, if the viewpoint was to move one unit to the right, then the inner ring (the one just around the view point + white center square) would end up getting a 1 unit space on both the left and right side of itself. But there is nothing in the paper that deals with this, what i mean is that it would end up looking like this (excuse my crummy cut-and-paste editing of the above image): This is obviously not a valid state of the. So, would the solution be that a clip ring (layer) can only move in increments of the ring/layer it's contained within? Wouldn't this end up being very restrictive? I feel like I am missing some crucial understanding of parts of the algorithm, but I have been over both this paper and the original paper from 2004 and I just can't see what I am not getting.

• Fujitsu Siemens V6535 laptop doesn't wake up - crash when going into standby?

  - by marc

  I'm having trouble with my laptop (Fujitsu Siemens model V6535). It runs Windows 7, and after I upgraded from Vista I've noticed something that makes me really angry. When my laptop goes into Standby, the power LED changes to red and starts blinking (standby mode). When I push the power button to wake it up it, the blinking LED changes to green but nothing else happens. Nothing on the display, no HDD sound. When I press the power button for a few seconds and then try turn it on again, it doesn't display anything. I have to unplug the charger, shut it off, and power it on again without the power cable. Then it starts working. A few days ago I upgraded the BIOS to the newest version, but it doesn't help. Does anyone have any idea what can be wrong?

• How many hours of use before I need to clean a tape drive?

  - by codeape

  I do backups to a HP Ultrium 2 tape drive (HP StorageWorks Ultrium 448). The drive has a 'Clean' LED that supposedly will light up or blink when the drive needs to be cleaned. The drive has been in use since october 2005, and still the 'Clean' light has never been lit. The drive statistics are: Total hours in use: 1603 Total bytes written: 19.7 TB Total bytes read: 19.3 TB My question is: How many hours of use can I expect before I need to clean the drive? Edit: I have not encountered any errors using the drive. I do restore tests every two months, and every backup is verified. Edit 2: The user manual says: "HP StorageWorks Ultrium tape drives do not require regular cleaning. An Ultrium universal cleaning cartridge should only be used when the orange Clean LED is flashing." Update: It is now May 2010 (4.5 years of use), and the LED is still off, I have not cleaned, backups verify and regular restore tests are done.

• IIS 7 - Application pools

  - by vikp

  I made a CompanySite website in IIS - it's the only website on that server. I created .NET 4 Integrated pool for that website. I've installed ASP.Net site into CompanySite and it works fine. Now I'd like to install an application within this site. I create another .NET 4 application pool for that application. Then I install application into CompanySite using that application pool. As soon as setup starts off the website goes offline either with 503 or with The page cannot be displayed because an internal server error has occurred. The only way to fix this (that I have found) is to uninstall that application and restart Windows Server, not just IIS server. Question is how can I install multiple applications within a single site? THank you

• RPi and Java Embedded GPIO: Hooking Up Your Wires for Java

  - by hinkmond

  So, you bought your blue jumper wires, your LEDs, your resistors, your breadboard, and your fill of Fry's for the day. How do you hook this cool stuff up to write Java code to blink them LEDs? I'll step you through it. First look at that pinout diagram of the GPIO header that's on your RPi. Find the pins in the corner of your RPi board and make sure to orient it the right way. The upper left corner pin should have the characters "P1" next to it on the board. That pin next to "P1" is your Pin #1 (in the diagram). Then, you can start counting left, right, next row, left, right, next row, left, right, and so on: Pins # 1, 2, next row, 3, 4, next row, 5, 6, and so on. Take one blue jumper wire and connect to Pin # 3 (GPIO0). Connect the other end to a resistor and then the other end of the resistor into the breadboard. Each row of grouped-together holes on a breadboard are connected, so plug in the short-end of a common cathode LED (long-end of a common anode LED) into a hole that is in the same grouping as where the resistor is plugged in. Then, connect the other end of the LED back to Pin # 6 (GND) on the RPi GPIO header. Now you have your first LED connected ready for you to write some Java code to turn it on and off. (As, extra credit you can connect 7 other LEDs the same way to with one lead to Pins # 5, 7, 11, 13, 15, 19 & 21). Whew! That wasn't so bad, was it? Next blog post on this thread will have some Java source code for you to try... Hinkmond

• Using Bazaar (BZR) on AFT or SMB mounted server not wroking

  - by Dan Berlyoung

  Has anyone been able to get BZR working on a mounted AFT or SMB mounted share? I've tried both (The AFP volume is actually coming off an Xserver.) and neither work. I have BZR 2.0.0 and am running it on a Mac with 10.5. I keep getting an error like this bzr: ERROR: Could not acquire lock "/Volumes/joeserver/Documents/bzr/remote_test/.bzr/checkout/dirstate": [Errno 45] Operation not supported I googled around a bit but only found a fairly stale (2007) bug report on launchad.com (Bug #313625 to be specific.) Any ideas?

• Web hosting providers for businesses (with offsite backups, disaster recovery options, etc.) [closed]

  - by Harry Muscle

  Possible Duplicate: How to find web hosting that meets my requirements? I'm wondering if anyone can point me in the direction of a couple of web hosting providers that are geared towards businesses. By this I mean providers that make it easy to create daily off site backups, are aware that websites require disaster recovery options and have these in place or are able to assist with them, etc. We currently have about a dozen sites with various providers, however, I've been asked to consolidate all of these into one provider and create a full disaster recovery plan. Unfortunately it seems like most providers are geared towards average users that don't require all these extra bells and whistles that businesses need. For example, HostGator, which is a very popular and well reviewed provider, doesn't even allow you to schedule full backups, they have to be manually requested via cPanel and then downloaded once available. If anyone can point out a couple companies that might be able to help with these sorts of things that would be much appreciated. Thanks, Harry P.S. I should also add that we are hoping to stay away from having to manage our own server, we're hoping for a fully managed solution like what HostGator would offer for example.

• Can a switch consume bandwidth?

  - by aashiq

  I have a network with a router and a switch. At first my ISP's optical fiber is connected with media converter input port. Than Ethernet cable (output port of Media converter) is connected with the switch. Then an output Ethernet cable is connected with our inner Microtik router. Then this router is connected with another LAN switch. From this switch we have got every connection other switch. It is our total network structure. Our bandwidth is 2 Mbps. From the 11th of March our MRTG graph shows high all the time even when my all switch is switched off except LAN switch. That's why our line is breaking up (Voice call). How could be it possible? My all PC's bandwidth is limited but when connected PC with media converter directly then the graph shows normal. That's why I can't blame my ISP.
