• SonicWALL NetExtender - Client Install?

  - by JArmani

  We are about to push out a new VPN solution for our organization. One of the beautiful things we saw in SonicWALL's SSL-VPN was the thin, browser-based solution of NetExtender. Does anybody have experience with this? My specific concern is that, at least in Windows 7 during testing, it prompts for admin credentials to install the ActiveX NetExtender plugin, which is standard for installing anything in a Windows domain environment. But doesn't this mean I actually have to go in and install the client on all domain laptops that will be using the VPN in the field? They wouldn't actually be able to simply visit the site and run the client, as advertised? By the way, we're using the SonicWALL NSA 3500 device. We do have ManageEngine's Desktop Central, which can push out software installations, but it usually has to be in the form of a .MSI package. Is there any solution to this, besides hitting up all my organization's computers?

• What SATA drive should I install FreeBSD onto? i.e. ar0 vs da0 vs ad4/5

  - by Matt

  I'm installing FreeBSD 8.0 on a server that has hardware SATA Raid. I'm just wondering. What is the difference between these devices. i.e. ar0, da0, ad4, ad5 I take it that ad4 & 5 are my two disks. Somehow the OS can see them individually even though it's one logical mirrored drive. Should I be installing it onto ar0 or one of the adX disks. What is da0? it's smaller than the others. ar0 is not some kind of software raid device is it? Just want to make sure I don't mess this up right from the get go.

• Session cach and tmp folder error on cPanel Centos

  - by Danialzo

  One of my clients has come across multiple breakdowns in their websites with the following error PHP Code: Warning: session_start() [function.session-start]:open(/tmp/sess_1d6616afe1b8a0d91a8d9ec29254b453, O_RDWR) failed: No space left on device (28) in /home/***/public_html/system/library/session.php on line 11Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/***/public_html/index.php:104) in /home/***/public_html/system/library/session.php on line 11Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/***/public_html/index.php:104) in /home/***/public_html/system/library/session.php on line 11Warning: Cannot modify header information - headers already sent by (output started at /home/***/public_html/index.php:104) in /home/***/public_html/index.php on line 177Warning: Cannot modify header information - headers already sent by (output started at /home/***/public_html/index.php:104) in /home/***/public_html/system/library/currency.php on line 45&#65279;Notice: Error: Can't create/write to file '/tmp/#sql_4c5_0.MYI' (Errcode: 28) Error No: 1 They are experiencing this problem while: Nothing has been recently changed on the server tmp and other folders are occupied with not more than 10% of their total space The error come and goes I would really appreciate it if anyone could guide me through.

• Windows Server 2008 R2 foundation VM unable to detect network adaptor

  - by user50273

  I created a Windows Server 2008 R2 foundation VM on Windows Server 2008 using Hyper-V. But I am not able to connect to internet from the VM. If I goto device manager, the network adapter branch itself is missing. I searched in google and few sites suggested I need to install the Integration Services although in one site they said Server 2008 R2 comes with integration services installed. Anyways I tried to install IntegrationServices using hyper-v but I get error dialog "error: unable to launch one of the update programs". Any suggestions on what am I supposed to do?

• df-h command in ubuntu

  - by Esha Sharma

  I am a new user of Ubuntu. When I type df -h in terminal , it gives me list of all storage devices and space usage. In my system I get this. Filesystem Size Used Avail Use% Mounted on /cow 934M 173M 761M 19% / udev 925M 4.0K 925M 1% /dev tmpfs 374M 856K 373M 1% /run /dev/sdb1 7.5G 2.8G 4.8G 37% /cdrom /dev/loop0 1.5G 1.5G 0 100% /rofs tmpfs 934M 16K 934M 1% /tmp none 5.0M 0 5.0M 0% /run/lock none 934M 76K 934M 1% /run/shm /dev/sda 299G 74M 299G 1% /media/q I understand that /dev/sda is my hard drive which is 320 gb(in gib it is 299 and hopefully that is what is being displayed) and /dev/sdb1 is pendrive of 8gb from which I am running the live cd. My question is what are the other folders and what is the physical location of these folders if complete memory is taken by the device dev/sda?

• Detecting hardware and installing drivers in Windows XP

  - by JL.

  I have on my desk a computer that I am reinstalling. I have just completed the Windows XP install , which is professional service pack 3. I have also installed an AV package. Now it is time to install the audio and display drivers. Windows Update does not detect the Display card, and neither the audio device. I really have no idea what devices are present in this system, and I am thinking of opening the case, and reading some IDs from the cards themselves. Before I do this, is there not some kind of tool that can automatically detect hardware and install drivers automatically. If not then at least tell me what devices are present, with some real descriptions, so I can search for drivers.

• Installing Chrome OS on HP Pavilion

  - by Lenny K

  Trying to install Chrome OS on HP Pavillion tx1000. I changed the BIOS to boot from USB before hard drive, and created a bootable USB drive (SanDisk Cruzer 4GB). No matter how many ways I try to make the USB drive, the laptop hangs on the startup screen, and trying to open the Boot Order Options freezes on "Fixed disk 0: ...". On the other hand, without the USB plugged in, the computer continues, and displays "Initialized Mouse", and then onto the Boot Order Options. If you let it boot normally from the beginning, it starts up fine into Windows Vista. I am using Hexxeh's Chrome OS build. Here are the different methods I've tried for making the Bootable USB Drive: Hexxeh's Image Creator (for Mac) Making the USB device bootable (using these directions). I wrote the image using Win32DiskImager. Writing the image using Win32DiskImager (without making it bootable).

• Sudden slow read & write speed on all IO

  - by user23392

  I have a custom built rig that has 2 storage drives. for OS: Western Digital 1.0TB HARD DR 64MB for other stuff: Corsair Performance 3 128GB (SSD) [ expected read speed: 400 mb/s ] The system was incredibly fast for a couple of months, then one day i was playing a game then it started to get buggy (some sounds and objects disappearing), i stopped the game and the system seemed to be unstable so i had to shut it down, next morning i couldn't start it up, it was saying something about corrupt device. I formatted both disks and installed a fresh copy of windows, all i can say that since that day the system was never like before, it takes 10 minutes to boot up (the icons and desktop slowly appear). but once it's done the slowness isn't as noticeable. Here's my benchmark on the HDD ( read speed - write speed ): And the SSD: Anyone knows what could be the issue?

• MacBook repeatedly disconnects from WiFi

  - by redwall_hp

  I have an early 2008-model MacBook (2.4GHz). The WiFi router I have at home is a Linksys WRT54GX2 that I have had for a few years. My MacBook has recently started disconnecting from the router every few minutes, which is rather annoying. I can reconnect again without having to restart the router or anything, as it seems that the MacBook is just dropping the connection. I have tried changing the channel on the router, and upgrading the laptop from Leopard to Snow Leopard made no difference either. I'm only about six feet from the linksys device, so distance isn't an issue. This only happens with the Linksys router, while I can use the local library's open network without issue. The problem also seemingly becomes more pronounced after midnight. Any ideas as to what the problem could be?

• Newly installed DIR-615 - how to connect to the wireless?

  - by JK123

  I've just installed a D-Link DIR 615, but can't figure out how to connect to the wireless.. When I double click my wireless icon in the tray, it does show the new network. Its starts the "WiFi protected setup wizard" and the first thing it asks for is the "Device Ownership Password". I have no idea what that is - I've tried the PIN and the router password. On the next page it says: SSID: _(name)__ Security type: _wpa2 personal aes ccmp_ Password: _some long key that is not what I entered during router setup_ I change the key to the one I created when setting up the router. I've also tried leaving the key as it is shown in the dialog. But it does not connect either way. All it says is "Configuration failed" So how do I connect to the new wireless network??

• Any way to release focus on a KVM guest in virt-manager without having to click Ctrl_L + Alt_L?

  - by slm

  Is there a way to move my mouse in and out of a KVM guest in virt-manager without having to click to gain focus of the window and release focus by pressing Ctrl_L + Alt_L? EDIT #1 The guest VM is Win2008R2. I've tried this on a CentOS 5, 6, and Fedora 14 box running various versions of virt-manager and KVM and they all exhibit this behavior. EDIT #2 I just tried the solution recommended by @tpow and that appears to be the issue. Manually adding a tablet input device resolves the problem and I can now move the mouse in and out of the KVM guest without having to gain focus first.

• Spoof MAC address in Windows 7: Bypass

  - by lpd

  I am trying to spoof the MAC address of my new Win7 laptop. To do so I tried specifying an alternate value from the Device Manager which took no effect. I also tried from the registry, as per other threads here, to no avail. Interestingly I also found the registry contained a path 000X\Ndi\params\NetworkAddress\default REG_SZ, but changing that had no effect either :( I can only guess I share the same issue here: http://forums.anandtech.com/showthread.php?t=2096480 as the wireless adaptor is the same brand bundled with the same operating system. So my question is - is there anything better I can do to achieve a spoofed physical address than rollback the drivers to some older version?

• HTTP Live Streaming Broadcast

  - by user761389

  I'm designing an app for streaming video from a device (e.g. iPhone) via a server to one or more devices and have been researching Apples HTTP Live Streaming protocol. One thing that isn't clear is whether it is possible to stream live video (with audio) to the server and then have it streamed simultaneously in real time to the client devices. From reading the documentation and technical notes from Apple it seems like the index file needs to be created before the segmented video files can be served to a client. Is this right? If so maybe HTTP Live Streaming isn't suitable in this case, what other technologies or software should I consider? Thanks

• How to setup IP alias on bridged interface in Ubuntu

  - by Anonymouslemming

  How do I setup an IP alias on a bridge (br0) device on Ubuntu ? If I wait for br0 to come up and then do /sbin/ifconfig br0:0 192.168.10.1 netmask 255.255.255.0 then it works fine. If however I add the following to my /etc/network/interfaces file, it does not work and the network fails to start: auto br0:0 iface br0:0 inet static address 192.168.10.1 netmask 255.255.255.0 At the moment, I have a script in /etc/network/if-up.d/bridge_alias that does this as follows: #!/bin/bash if [ "${LOGICAL}" == "br0" ] && [ "${PHASE}" = "post-up" ]; then echo -n "Starting br0:0 ... " /sbin/ifconfig br0:0 192.168.10.2 netmask 255.255.255.0 echo "Done!" fi What is the right way of doing this though, just using the OS network config files ?

• SNMP - So I have a MIB. Now What?

  - by senfo

  I can't seem to get my head wrapped around the purpose of a MIB. I have a collection of ~20 MIB files that were supplied to me by the vendor, but what do I do with them? I also have a few OID's that were supplied by the vendor that don't seem to be valid. When I issue an "snmpget -v1 -c public 192.168.0.123 .1.4.6.3.2.6.2" (assume that's a valid OID), I get an error indicating the variable is unknown. Does this sound like a hardware configuration problem? Do I need to "load" (for lack of better words) the MIB into the device? Unfortunately, the vendor has been completely unresponsive with returning emails to my questions, so any help would be greatly appreciated.

• Windows XP SP3 dissapearing mapped drives

  - by Alan Spark

  I am running Windows XP Pro SP3 and I've got a few shares on my NAS that are mapped to reconnect automatically. I can access the drives soon after starting windows but after a period of inactivity I get the error "The local device name is already in use". This cannot be remedied until I restart the computer - I've tried disconnecting and re-mapping without success. This was working fine until I recently reinstalled Windows and I'm not sure what is going on. Any help would be greatly appreciated. Thanks, Alan

• Windows 7 Desktop as Bluetooth Mixer

  - by J.R. Lillard

  I would like to stream all the audio from my Droid X2 to my desktop running Windows 7 via bluetooth. When I pair the two devices I can make this work but the audio plays through the internal speakers. I am actually wanting to listen to everything through a pair of bluetooth headphones. The end result would be that I could listen to music from my phone but easily pause it to listen to audio from the desktop instead. So far I have not had any luck. I thought about connecting the line out to the line in so I could monitor the line in from my headphones. My current setup is wiring the phone to the line in and then monitoring the line in through the headphones. I'm just wanting to eliminate the wire and go wireless the whole way. Is there something in Windows that prevents it from taking an inbound audio stream and sending it out another device?

• Using FlashCache on /var on startup

  - by WinkyWolly

  I would like to have FlashCache cache my /var partition however I can't seem to get it to play nice upon bootup (IE: not really sure how to do it). I'm not sure if I need to modify the initramfs/use DKMS or if I can do it in user-land during bootup. The issue I'm running into is /var mounts early and therefore the device is busy (whether it by generally by syslogd). I'm positive this can be resolved by modifying the initramfs although I simply haven't fiddled with it enough to get it working. They have instructions on how to boot your root partition however I'm not sure if these instructions would apply to my use case. Any help / pointers in the right direction would be absolutely splendid.

• Is there a way to share a scanner with an Airport Extreme?

  - by Electrons_Ahoy

  I've got an Airport Extreme as my home network's router. (Sidebar: I love it.) The printer sharing is pretty phenomenal - I've got my printer hooked up to the base station and all the machines in the house can print to it just fine. However, I have one of those combined scanner/printers, and nothing on the lan seems to be able to see the scanner. Is there a way to get the Airport Extreme / Bonjour to also share the scanner half of the device? For the record, this is an all Windows LAN, so I'm using Bonjour for Windows to get the print sharing to work. Also, I'm hoping to not add a whole stack of extra software to the ecosystem - only one machine in the house needs the scanner, so I can just plug the printer back into that machine and share the printer that way. Still, the Airport and Bonjour seem fancy enough that this seems like it should be doable.

• Need Assistance on ASUS K55V USB ports not working

  - by Pascal Schilling

  I have a K55V ASUS laptop, W7 Home (64bit). Whenever I try to use a mouse (or any other USB device), it doesn't work because of a driver problem. The automatic update tries to update the driver and requires me to reboot directly after. It doesn't work. Windows update then wants to re-attempt the update and then I have to reboot (etc). Now, after 10 tries it still doesn't work. Can some one help me out on this? No USB ports work at the moment, it has 2 USB 3.0 ports and 1 USB 2.0 port.

• Is A Managed Switch With VLAN Support Required

  - by Justin

  Hello, I am wondering if I need to buy a switch which is managed (VLAN support) for my configuration, or will a cheaper unmanaged switch work? I have servers with two NICS each. The first NIC is public and the second NIC is private. The router will plug into the switch port 1 let's say (public). Then server 1 public plugs into port 2 on the switch, and sever 1 private plugs into port 3 on the switch. The public interface is: 192.168.X.X / 255.255.0.0 and the private interface is 10.0.X.X / 255.255.0.0. So looks like: ** SWITCH ** Port Device Network 1 Router/Firewall 192.168.X.X 2 Server 1 Public 192.168.X.X 3 Server 1 Private 10.0.X.X 4 Server 2 Public 192.168.X.X 5 Server 2 Private 10.0.X.X 6 Server 3 Public 192.168.X.X 7 Server 3 Private 10.0.X.X Thanks.
