  • Second CPU missing of Dual Core

    - by Zardoz
    My Lenovo T61 has a dual core CPU. I just noticed that under Ubuntu 10.10 only one CPU is recognized. I know that once both CPUs worked. Not sure since when the second CPU is missing. Maybe since the last kernel update. Currently I am using linux-image-2.6.35-23-generic (for x86_64). What can I do to enable the second CPU again? Here the ouput of /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Core(TM)2 Duo CPU T8100 @ 2.10GHz stepping : 6 cpu MHz : 800.000 cache size : 3072 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 lahf_lm ida dts tpr_shadow vnmi flexpriority bogomips : 4189.99 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: Any help is welcome.

  • How to handle OpenVPN client as a service, when the laptop is physically on the network already?

    - by James
    The Setup I've gotten OpenVPN working on our Windows XP laptops. Users are limited, so I went ahead and set OpenVPN client to run as a service, which is great anyway because that means they are on the VPN before logging in, so login scripts work, plus we can do remote support even if the user can not log in (such as connecting via VNC or resetting passwords). It is also configured to send all traffic over the tunnel, so when, for example, they browse the internet it is just like browsing from our corporate network. The Qestion(s) So, I'm wondering how does the OpenVPN client act when the computer is already physically on the same network as the OpenVPN server? Right now, the client is configured to connect the the public dns name which will resolve to the public ip address which will NOT get reflected back to the OpenVPN server, so it is affectively blocked from connecting to the OpenVPN server while on the network. Is that a good thing? Or will it constantly try to connect, using up system resources and network resources? We will likely have hundreds of laptops regularly on the physical network with this, so it could contribute to a lot of unnecessary network chatter. Alternatively Would it be better to have the firewall reflect the port back to the OpenVPN server and let it connect? Or have our internal dns resolve the name to the private ip and allow them to connect directly? Would traffic then go over the vpn connection (which I do not want, when already on the physical network)? Or is it possible to tell it to ignore the connection when the client and server are already on the same network? TLDR What's a sane way of handling OpenVPN client running as an always-on service when the client and server will often be on the same network?

  • Can't Connect SQL server - process being used by another process. Conflict with IIS?

    - by shinya
    I'm having problem connecting to MS SQL Server (2012 Express) after accessing a database through IIS (web site). I can access the data through web site no problem, but I can't access the data from any other programs (i.e SSMS) until I reboot the SQL server. It seems that the connection stays open even if I close a browser. Here is error message I'm getting Unable to open the physical file "C:---------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Unable to open the physical file "C:-------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Cannot open user default database. Login failed. Login failed for user 'Myserver\myname'. (.Net SqlClient Data Provider) Server Name: MYPC\SQLEXPRESS Error Number: 5120 Severity: 16 State: 101 Line Number: 65536 I follow the help link and it told me to move TCP before named pipes in the protocol order list. I tried it but it didn't help at all. What is the proper settings on SQL server or IIS in order to release process after closing a browser. How do I avoid getting this error? Thank you for your help

  • Getting dwl-g122 to work on ubuntu

    - by User1
    I have a USB WiFi adapter, D-Link dwl-g122. I'm running Ubuntu 10.4. My laptop has a built-in wireless card that is connecting fine to the router. I plug in the usb and it never really connects.

  • Windows 2008 R2 DNS cant resolve own SOA

    - by user46742
    We have two Domain Controllers for our network. They both run DHCP, DNS, and ADS. They are both VM's sitting on MS Hyper V Server 2008 on separate physical hosts. We had our primary DC go down a week ago. I upgraded an already existing VM to Primary DC and built a new VM for the secondary. Both DNS servers are running and the SOA is configured correctly for Primary DC 1. However when I run the best practice analyzer it states the server cannot resolve it's own SOA. Check the configuration in the adapter. I checked and they are configured properly. I also went through the DNS entries thoroughly and made sure there was no records of the previous DC that went down. NSLOOKUP resolves the domain and primary dc fine. I also checked the firewalls on the machines and our physical firewall for any deny packets. Any suggestions? I appreciate any help!

  • A switch and router between the printer and PC that want to print but cannot

    - by Robert Memo
    IP 192.168.1.5 has a wireless connection to a Linksys router (192.168.1.1) which then is connected to a switch. The switch is connected to a server (192.168.0.2). My printer has IP address of 192.168.0.8. Internet connection is fine on 192.168.1.5. Problem 1: IP 192.168.1.5 can not print using printer 192.168.0.8. Problem 2: IP 192.168.1.2 can not access a shared folder on the the server. The reason for connecting this way is that, the server does not release wireless signal. In order to get wireless signal the Router is connected to the switch. The server is a computer server that only has one outgoing LAN port. Plus, due to inconvinience physical locations, I do not have option to change the physical locations and the way it is connected already. I just want the labtops that only have wireless connection to communicate with the printer and the server. I have tried to change the router IP address to 192.168.0.x like the server and printer. It caused problem for the laptop. The router no longer release internet signals. The router does have IP address from the server 192.168.0.5.

  • Hyper-V VM's cannot access Host resources, and vice-versa

    - by Agent
    I have several Hyper-V vm's running on this Win2008 R2 Server box, and up until a reboot of the host server, all the VM's were able to access shared folders on the host. Now, they can't even ping the host server. From what I've seen, I need to setup an Internal only network through Virtual Network Manager in Hyper-V. I set this up, then tried to enable the Microsoft Virtual Network Switch Protocol option in this Internal Only NIC, but I get popups saying: Your current selection will also disable the following features: Microsoft virtual network switch protocol Which is absolutely stupid, considering the protocol is what I'm ticking the checkbox to Enable! As of now, on the host, I have 2 NICs: Physical - This NIC on the host machine does have the MVNS protocol enabled Virtual Network Adapter - Created through Hyper-V Virtual Network Manager as an External type of network. Trying to enable MVNS on this NIC also produces the error above. I've tried enabling Client for Microsoft Networks on the physical NIC for IPv6, but everytime I do that, all the VMs lose Internet connectivity and I cannot RDP into them. Anything else I can try?

  • What causes a switch port to receive data not destined for it?

    - by user1693454
    We are having an intermittent fault which is effecting one of our control systems on one of our HP Procurve switches. For some reason, this PLC (10mbit port - 192.168.6.56) which is attached directly to the HP Switch intermittantly start's receiving data which is not destined for it. The data is being sent from a Thecus NAS with latest firmware (192.168.6.218) to a physical IBM Server running Win2003R2 and SAP (192.168.6.225). The problem does not just send to this server, it has been to other physical servers in the past too, but always from the Thecus NAS. I am using a monitor port to wireshark what is going in/out of the PLC - normally there would be about 1mb in/out per 2 or 3 minutes - only a server asking the state of the coils. When the problem occurs, there is a flood of data being put onto the PLC line - in this captured instance, about 67mb in less than a minute. Due to this, there is no way that the PLC can be queried as the port is effectively DOSed, in turn killing part of our factory. I know that having Production on the same vlan as IT is not a good idea - I agree, however it cannot be changed at the moment (will have to wait 3 months), as well as the problem has only started happening in the last 3 months. Here is a screen cap of one of the packets being sent from the Thecus NAS which was captured from the PLC port on the HP Switch: And there are over 700 of these in this one 1024kb file. If anyone has any idea on what could be going on, some help would be greatly appreciated. If you need to know anything more, let me know! Cheers!

  • Almost All Logical Volumes Disappeared - Recovery?

    - by Alex
    We had a hard disc crash of one of two hard discs in a software raid with a LVM on top. The server is running Citrix xenserver. On the hard disk which is still intact, the volume group gets detected well, but only one LV is left. (some hashes replaced by "x") # lvdisplay --- Logical volume --- LV Name /dev/VG_XenStorage-x-x-x-x-408b91acdcae/MGT VG Name VG_XenStorage-x-x-x-x-408b91acdcae LV UUID x-x-x-x-x-x-vQmZ6C LV Write Access read/write LV Status available # open 0 LV Size 4.00 MiB Current LE 1 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 root@rescue ~ # vgdisplay --- Volume group --- VG Name VG_XenStorage-x-x-x-x-408b91acdcae System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 698.62 GiB PE Size 4.00 MiB Total PE 178848 Alloc PE / Size 1 / 4.00 MiB Free PE / Size 178847 / 698.62 GiB VG UUID x-x-x-x-x-x-53w0kL I could understand if a full physical volume is lost - but why only the logical volumes? Is there any explanation for this? Is there any way to recover the logical volumes? EDIT We are here in a rescue system. The problem is that the whole server does not boot (GRUB error 22) What we are trying to do is to access the root filesystem. But everything was in the LVM. We have only this: (parted) print Model: ATA SAMSUNG HD753LJ (scsi) Disk /dev/sdb: 750GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 750GB 750GB primary boot, lvm And this 750GB LVM volume is exactly what we see on top.

  • LMDE detects a wireless card, but can't use it

    - by Davidos
    LMDE can see my wireless card, and correctly identifies it, but it refuses to let me turn it on through the shiny graphical interface. Is there a way to use the non-shiny terminal to turn on my wireless? One small tidbit I noticed was the stated version; it says the version is 00. I believe that's hexadecimal for 0, which may indicate something screwy with the software. It would be nice if someone could tell me how to figure out how to solve this kind of problem in the future. *-network DISABLED description: Wireless interface product: Centrino Wireless-N 1000 vendor: Intel Corporation physical id: 0 bus info: pci@0000:09:00.0 logical name: wlan0 version: 00 serial: 91:e3:7b:0d:a3:a9 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlagn driverversion=3.0.0-1-amd64 firmware=39.31.5.1 build 35138 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:43 memory:e1d00000-e1d01fff I've tested multiple other network managers, and none of them work.

  • RDP with multiple monitors, display preferences get reset?

    - by Martijn Kooij
    Problem: When I connect to my pc at the office via RDP all the application windows I had previously carefully placed on either monitor 1 or 2 will be "scrambled". Either all applications show on monitor 1 and monitor 2 is empty, or they have switched 1 <- 2. Expected behaviour: When I connect I see all the application windows on exactly the same position and in the exact same size as I left them the night before. I have the exact same monitors at home as I have at work: Primary 2560x1440, Secondary 900x1440. Yesterday I tried switching the physical cables on the host machine hoping that the hardware order of the monitors was the difference. But this morning my secondary monitor was completely blank, not even the taskbar (which I had set to ONLY show on the secondary). Somewhere there must be something to help Windows understand which physical monitor is which virtual RDP monitor is which RDP "server" monitor... Are there more options than switching the cables? This one has been bothering me for a long long time now, I hope someone has a solution or workaround for me. Edit I want to use both monitors, so I have checked the "Use all monitors" setting in the RDP client. For example I leave my mail and total commander on the right monitor, and visual studio and Firefox on the left monitor. When I connect to RDP I want to see those applications on the same positions and sizes.

  • VirtualBox bridged network not working as expected

    - by iby chenko
    I am having hard time getting Bridged network to work with VirtualBox. Idea is to have host as well as one or more guests on same LAN. Using NAT (default) I do get access to internet and any node on the LAN when working from one of the VM guests. However, no LAN node including host can access (or ping) guest in VM. I need to be able to use any guest as if it was a physical computer on the network (need to be accessed by any machine on LAN). According to my understanding of the VirtualBox documentation, this should be Bridged mode. I think I set it correctly, well, actually there is not much to it: 1. select Bridged mode in VM network setup 2. select physical NIC of the host to connect bridge to 3. start VM When I do this, each VM does get new IP address that corresponds to LAN settings : 192.168.1.100 192.168.1.102 192.168.1.103 etc. where host is 192.168.1.80 / 255.255.255.0 (IP addresses above 100 are served by DHCP server). This seem to be correct based on what I know about ethernet. From VM I can ping other nodes like 192.168.1.50 etc. and I still get ethernet access. So far so good... But I STILL cannot ping any of the other VMs (running ones of course). I cannot ping them from other VMs, from host or from other nodes on the LAN. Aside from fact that IP addresses handed to guests are now local, this still acts same as NAT. What is going on? What am I missing? Regards, I

  • Hungry hungry BIOS: why do I have less than 4 GiB of memory?

    - by Rhymoid
    I thought I had 4 GiB of memory, but just to be sure, let's ask the BIOS about that: ?: sudo dmidecode --type 20 # dmidecode 2.12 SMBIOS 2.6 present. Handle 0x000B, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00000000000 Ending Address: 0x0007FFFFFFF Range Size: 2 GB Physical Device Handle: 0x000A Memory Array Mapped Address Handle: 0x000E Partition Row Position: Unknown Interleave Position: Unknown Interleaved Data Depth: Unknown Handle 0x000D, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00080000000 Ending Address: 0x000FFFFFFFF Range Size: 2 GB Physical Device Handle: 0x000C Memory Array Mapped Address Handle: 0x000E Partition Row Position: Unknown Interleave Position: Unknown Interleaved Data Depth: Unknown Alright, 4 GiB it is. But I can't use all of it: ?: cat /proc/meminfo | head -n 1 MemTotal: 3913452 kB Somehow, somewhere, I lost 274 MiB. Where did 6% of my memory go? Now I know the address ranges in DMI are incorrect, because the ACPI memory map reports usable ranges well beyond the ending address of the second memory module: ?: dmesg | grep -E "BIOS-e820: .* usable" [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009e7ff] usable [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x00000000dee7bfff] usable [ 0.000000] BIOS-e820: [mem 0x0000000100000000-0x0000000117ffffff] usable I get pretty much the same info from /proc/iomem (except for the 4 kiB hole 0x000-0xFFF), which also shows that the kernel only accounts for less than 8 MiB. I guess 0x00000000-0x7FFFFFFF is indeed mapped to the first memory module, and 0x80000000-0xDFFFFFFF to part of the second memory module (a bunch of ACPI NVS things live between 0xDEE7C000 and 0xDEF30FFF, and the remaining 16-something MiB of that range are just 'reserved'). I guess the highest 0x18000000 bytes of the second memory module are mapped above the 4 GiB mark. But even then, there are two problems: 128 MiB (0x08000000 bytes, living somewhere between 0xE0000000 and 0xFFFFFFFF) are still completely unaccounted for. To note, my graphics card is on PCI-Express and (allegedly) has 1 GiB dedicated memory, so that shouldn't be the culprit. Did the BIOS screw up in moving the memory, leaving it partially shadowed by MMIO? Even with this mediocre explanation, I only 'found' 128 MiB. But /proc/meminfo is reporting a much larger deficit; where's the other 146 MiB? How does Linux count MemTotal?

  • vmware server 64 bit on ubuntu 9.10 64 bit with P2V windows 2003 SBS poor network speed

    - by RobertHC
    configuration is ubuntu 2.6.31-21 64 bit vmware 2.0.2 64 bit last release hardware is core 2 quad with 8GB ram guest is win 2003 server SBS 32 bit Dear friends, we have a converted physical to virtual windows sbs 2003, converted with last converter available nowadays http://www.vmware.com/products/converter/ vCenter converter. Running the P2V 2K3 SBS on vmware server, it does boot fine, but we do note an abnormal CPU activity and a poor lan speed. As attempts we did what follow. We removed all unneeded peripherals, we removed one NIC (phisycal server was 2 nics), we changed the vmx to ged the nic recognized as intel instead than amd, we removed 1 cpu (physical was 2 cpu), we removed anything was reported as failed driver from system events monitor. Nothing to do, no way and funny results. Let's read some tests results. All are made with the same file copied in different source folders. Copying from client side (both directions copy, to/from server) results are i.e. 10 seconds, copying the same files from server side (again from and to server) results are different... from client to server, speed is round about (bit more) 10 seconds, but from server to client direction is slower: double the time. Beeing very fast and launching a simultaneous copy "from server to client"+"from client to server", this made from the server side, results in a stuck traffic... 45 seconds to do the copy. vmware tools are installed and e1000 driver has been updated. With one processor CPU activity is still going up and down but much less than with two. Because of test, we installed win 2k8 STD 64 bit. We repeated all the above tests with exactly the same file result is just one: always 5 seconds (this matches the lan speed) Any idea about this issue is welcome and thank you if any. Kind regards R.

  • windows server 2003 speed issues

    - by farzinSH
    I have a HP server with windows server 2003 and 50 windows XP clients. Since a week and a half the networks speed suddenly drop 2-3 times per day. It gets so slow that none of the clients could work with the HIS program installed on them. We tried so many different things such as replacing the hubs,switches and even some wires. Every time one of these changes solves the problem and the network goes back to its normal state. I checked everything. Even when I disconnected all the clients from the server and connected it to just one computer the problem still remained for 2 hours. I just narrowed down the problem to the couple of likely speculations as follows: viruses? (Updated Kaspersky running on the server shows none) server hardware failure? Physical memory usage on the server? (Because the last time the problem occurred none of the changes above solved the issue so I restarted the server an checked the physical memory usage which was 2 GBs. But I noticed it's increasing over time to over 9 GBs...the server has 16 GBs of RAM.) I surfed the internet and got nothing. Any help would do us a lot....thanks in advance

  • Renaming VLAN Interfaces in Linux

    - by rhololkeolke
    I need to know how to rename VLAN interfaces. I'm currently running Ubuntu 11.04. I'm running a networking application that takes frames on one interface applies things like delays and errors and then forwards the frames out another interface. The default naming convention which names things <interface>.<vlan> e.g. eth0.2 will not work for my purposes because the program which parses the configuration script for the networking application doesn't like the decimal in the interface name. I ran vconfig set_name_type VLAN_PLUS_VID which solves the decimal in the interface name problem, however, I can then no longer assign the same vlan id to multiple interfaces because they have the same name. I know how to change physical interface names using udev rules, but because the vlan's will have the same MAC address and they aren't physical interfaces I can't use those rules to rename the interfaces. Is there a way to rename any interface in linux, including the virtual ones? Is there a way to specify your own naming convention for config set_name_type option without having to recompile the source of vconfig?

  • Computers on network crashing

    - by Phil Cross
    We have recently upgraded our network to Windows 7 clients with Windows server 2008 servers. The upgrade was completed by the end of September and until now has been fine (apart from the minor bugs). Recently (within the last 2 weeks) we've notice all computers on the network (around 1000) start to slow down to the point their unusable. It starts at about 08:45 and finishes at 09:15. Because of this, we think something may be broadcasting across the network. This happens every day, between these times. I cant use my computer at all at the slowdown peak, and looking at task managers performance graphs, Physical memory is hovering around 35% and CPU usage is at 0-10% (idle) yet still crashing. I've looked on DHCPs server log and cant see anything which stands out. The only change we made prior to the slowdown was installing adobe CS6 on some computers, however the slowdown affects computers without CS6. We have 2 physical machines, each with around 5-7 virtual machines running on them with ample memory. Does anyone have any suggestions as to what we can do to narrow down whats causing the crashes? Any help, suggestions or advice would be appreciated.

  • Slow network interaction between 2 kvm host machines

    - by VirtualNoob
    We have 2 physical machines, Host1 is a CentOS 6.4 kvm host and hosts ~7 kvm VMs all running Ubuntu 12.04 - all of this runs perfectly. Recently we've added a 2nd host system, host2, again a CentOS 6.4 kvm host with a view to running another couple of VMs and providing some failover against host1 should it be required. Both physical machines reside in the same cabinet in our DC, and are on the same subnet - let's say host1: 1.1.1.64 and host2: 1.1.1.81. Both have their gateway set to the DC gateway of 1.1.1.254 with no hardware firewall in between. On each machine, I have 4 NICs that are bonded together to form a single interface, which is then bridged to allow the VMs to access the network. All of the VMs are online, and all of them can successfully ssh into the hosts without any delay. Both systems can access the internet fine, and I can ssh into both systems from home without any issues. However, there is a real delay when attempting to ssh from host1 to host2 (or vice versa) and this obviously means that any action required on host2, that is controlled by host1 either takes forever or results in failure due to timeout. In the interest of keeping this post short, I've put my ifcfg files into a pastie: http://pastie.org/8081648 I've tried both adding a firewall rule in each machine for the other, and also disabling the firewall entirely, so that can't be the issue. I've tried troubleshooting this myself but can't seem to get to the bottom of it. Any help or advice would be appreciated. Thanks in advance.

  • Windows 7 laptop with two active network connections will not perform DNS AAAA lookup under certain conditions

    - by Jeff Loughridge
    My laptop has two network interfaces. The Ethernet interface connects directly to my provider's edge router. It obtains an IPv6 address via SLAAC. I manually set an IPv6 DNS server. The wireless interface connects to a CPE router that doesn't understand IPv6. If the wireless interface is disabled, I can reach the IPv6 Internet with no problems using the Ethernet interface. I run into problems when both interfaces are enabled and the wireless interface get its IPv4 DNS server via DHCP. Let's look at two scenarios. Wireless interface obtains IPv4 DNS server via DHCP - The CPE router (192.168.0.1) sends its address as the DNS server. In this scenario, Windows 7 will not perform AAAA lookups. The browser uses IPv4 transit to reach dual stack web sites. I can't reach IPv6-only web sites using domain names. I can reach IPv6-enabled web sites using IPv6 literals instead of the domain name. Wireless interface is manually configured with OpenDNS DNS server - Windows 7 performs AAAA lookups using IPv6 transit (via the Ethernet). Everything works fine. My dual homed set-up is definitely not standard. Still, the behavior is very strange to me. A valid IPv6 interface exists in my Ethernet interface. Why won't Windows attempt AAAA lookups in scenario #1? I've included the output of ipconfig /all and netstat -rn.

  • Jolicloud is a Nifty New OS for Your Netbook

    - by Matthew Guay
    Want to breathe new life into your netbook?  Here’s a quick look at Jolicloud, a unique new Linux based OS that lets you use your netbook in a whole new way. Netbooks have been an interesting category of computers.  When they were first released, most netbooks came with a stripped down Linux based operating system designed to let you easily access the internet first and foremost.  Consumers wanted more from their netbooks, so full OSes such as Windows XP and Ubuntu became the standard on netbooks.  Microsoft worked hard to get Windows 7 working great on netbooks, and today most netbooks run Windows 7 great.  But the Linux community hasn’t stood still either, and Jolicloud is proof of that.  Jolicloud is a unique OS designed to bring the best of both webapps and standard programs to your netbook.   Keep reading to see if this is the perfect netbook OS for you. Getting Started Installing Jolicloud on your netbook is easy thanks to a the Jolicloud Express installer for Windows.  Since many netbooks run Windows by default, this makes it easy to install Jolicloud.  Plus, your Windows install is left untouched, so you can still easily access all your Windows files and programs. Download and run the roughly 700Mb installer (link below) just as a normal installer in Windows. This will first extract the needed files. Click Get started to install Jolicloud on your netbook. Enter a username, password, and nickname for your computer.  Please note that the username must be all lowercase, and the nickname should not contain spaces or special characters.   Now you can review the default installation settings.  By default it will take up 39Gb and install on your C:\ drive in English.  If you wish to change this, click Change. We chose to install it on the D: drive on this netbook, as its harddrive was already partitioned into two parts.  Click Save when your settings are all correct, and then click Next in the previous window. Jolicloud will prepare for the installation.  This took about 5 minutes in our test.  Click Next when this is finished. Click Restart now to install and run Jolicloud. When your netbook reboots, it will initialize the Jolicloud setup. It will then automatically finish the installation.  Just sit back and wait; there’s nothing for you to do right now.  The installation took about 20 minutes in our test. Jolicloud will automatically reboot when the setup is finished. Once it’s rebooted, you’re ready to go!  Enter the username, then the password, that you chose earlier when you were installing Jolicloud from Windows. Welcome to your Jolicloud desktop! Hardware Support We installed Jolicloud on a Samsung N150 netbook with an Atom N450 processor, 1Gb Ram, 250Gb harddrive, and WiFi b/g/n with Bluetooth.  Amazingly, once Jolicloud was installed, everything was ready to use.  No drivers to install, no settings to hassle with, it was all installed and set up perfectly.  Power settings worked great, and closing the netbook put it to sleep just like in Windows. WiFi drivers have typically been difficult to find and install on Linux, but Jolicloud had our netbook’s wifi working immediately.  To get online, simply click the Wireless icon on the top right, and select the wireless network you want to connect to. Jolicloud will let you know when it is signed on. Wired Lan networking was also seamless; simply connect your cable and you’re ready to go.  The webcam and touchpad also worked perfectly directly.  The only thing missing was multitouch; this touchpad has two finger scroll, pinch zoom, and other nice multitouch features in Windows, but in Julicloud it only functioned as a standard touchpad.  It did have tap to click activated by default, as well as right-side scrolling, which is nice. Jolicloud also supported our video card without any extra work.  The native resolution was already selected, and the only problem we had with the screen was that there was no apparent way to change the brightness.  This is not a major problem, but would be nice to have.  The Samsung N150 has Intel GMA3150 integrated graphics, and Jolicloud promises 1080p HD video on it.  It did playback 720p H.264 video flawlessly without installing anything extra, but it stuttered on full 1080p HD (which is the exact same as this netbook’s video playback in Windows 7 – 720p works great, but it stutters on 1080p).  We would be excited to see full HD on this netbook, but 720p is definitely fine for most stuff.   Jolicloud supports a wide range of netbooks, and based on our experience we would expect it to work as good on any supported hardware.  Check out the list of supported netbooks to see if your netbook is supported; if not, it still may work but you may have to install special drivers. Jolicloud’s performance was very similar to Windows 7 on our netbook.  It boots in about 30 seconds, and apps load fairly quickly.  In general, we couldn’t tell much difference in performance between Jolicloud and Windows 7, though this isn’t a problem since Windows 7 runs great on the current generation of netbooks. Using Jolicloud Ready to start putting Jolicloud to use?  Your fresh Jolicloud install you can run several built-in apps, such as Firefox, a calculator, and the chat client Pidgin.  It also has a media player and file viewer installed, so you can play MP3s or MPG videos, or read PDF ebooks without installing anything extra.  It also has Flash player installed so you can watch videos online easily. You can also directly access all of your files from the right side of your home screen.  You can even access your Windows files; in our test, the 116.9 GB Media was C: from Windows.  Select it to browse and open any file you had saved in Windows. You may need to enter your password to access it. Once you’re authenticated it, you’ll see all of your Windows files and folders.  Your User files (Documents, Music, Videos, etc.) will be in the Users folder. And, you can easily add files from removable media such as USB flash drives and memory cards.  Jolicloud recognized a flash drive we tested with no trouble at all. Add new apps But, the best part about Jolicloud is that it makes it very easy to install new apps.  Click the Get Started button on your homescreen. You’ll first need to create an account.  You can then use this same account on another netbook if you wish, and your settings will automatically be synced between the two. You can either signup using your Facebook account, …or you can sign up the traditional way with your email address, name, and password.  If you sign up this way, you will need to confirm your email address before your account will be finished. Now, choose your netbook model from the list, and enter a name for your computer. And that’s it!  You’ll now see the Jolicloud dashboard, which will show you updates and notifications from friends who also use Jolicloud. Click the App directory to find new apps for your netbook.  Here you will find a variety of webapps, such as Gmail, along with native applications, such as Skype, that you can install on your netbook.  Simply click the Install button on the right to add the app to your netbook. You will be prompted to enter your system password, and then the app will install without any further input.   Once an app is installed, a check mark will appear beside its name.  You can remove it by clicking the Remove button, and it will uninstall seamlessly. Webapps, such as Gmail, actually run in in a Chrome-powered window that lets the webapp run full screen.  This gives the webapps a native feel, but actually they’re just running the same as they would in a standard web browser.   The Jolicloud Interface Most apps run maximized, and there is no way to run them smaller.  This in general works good, since with small screens most apps need to run full-screen anyhow. Smaller apps, such as a calculator or the Pidgin chat client, run in a window just like they do on other operating systems. You can switch to another app that’s running by selecting it’s icon on the top left, or you can go back to the home screen by clicking the home screen.  If you’re finished with an program, simply click the red X button on the top right of the window when you’re running it. Or, you can switch between programs using standard keyboard shortcuts such as Alt-tab. The default page on the home screen is the favorites page, and all of your other programs are orginized in their own sections on the left hand side.  But, if you want to add one of these to your favorites page, simply right-click on it and select Add to Favorites. When you’re done for the day, you can simply close your netbook to put it to sleep.  Or, if you want to shut down, just press the Quit button on the bottom right of the home screen and then select Shut Down. Booting Jolicloud When you install Jolicloud, it will set itself as the default operating system.  Now, when you boot your netbook, it will show you a list of installed operating systems.  You can select either Windows or Jolicloud, but if you don’t make a selection it will boot into Jolicloud after waiting 10 seconds. If you’d perfer to boot into Windows by default, you can easily change this.  First, boot your netbook in to Windows.  Open the start menu, right-click on the Computer button, and select Properties.   Click the “Advanced system settings” link on the left side. Click the Settings button in the Startup and Recovery section. Now, select Windows as the default operating system, and click Ok.  Your netbook will now boot into Windows by default, but will give you 10 seconds to choose to boot into Jolicloud when you start your computer. Or, if you decided you don’t want Jolicloud, you can easily uninstall it from within Windows. Please note that this will also remove any files you may have saved in Jolicloud, so be sure to copy them to your Windows drive before uninstalling. To uninstall Jolicloud from within Windows, open Control Panel, and select Uninstall a Program. Scroll down to select Jolicloud, and click Uninstall/Change. Click Yes to confirm that you want to uninstall Jolicloud. After a few moments, it will let you know that Jolicloud has been uninstalled.  You’re netbook is now back the same as it was before you installed Jolicloud, with only Windows installed. Closing Whether you’re wanting to replace your current OS on your netbook or would simply like to try out a fresh new Linux version on your netbook, Jolicloud is a great option for you.  We were very impressed by it’s solid hardware support and the ease of installing new apps in Jolicloud.  Rather than simply giving us a standard OS, Jolicloud offers a unique way to use your netbook with native programs and webapps.  And whether you’re an IT pro or are a new computer user, Jolicloud was easy enough to use that anyone can do it.  Give it a try, and let us know what your favorite netbook OS is!

  • e-interview: SunSpace to WebCenter migration

    - by me
    I had the pleasure to do an e-interview with Ana Neves around the SunSpace to WebCenter migration project.  Below is the english version of the interview.  Enjoy   Peter, you joined Oracle in 2009 through the acquisition of Sun. Becoming a part of Oracle meant many changes. The internal collaboration platform was one of them, as per a post you wrote back in 2011. Sun had SunSpace. How would you describe SunSpace? SunSpace was the internal Community and Social Collaboration platform for the Sun's Global Sales and Services Organization. SunSpace served around 600 communities with a main focus around technology, products and services. SunSpace was a big success. Within 3 months of its launch SunSpace had over 20,000 users and it won the Atlassian "Not just another wiki" Award for the best use of Confluence (https://blogs.oracle.com/peterreiser/entry/goodbye_sunspace_hello_webcenter). What made SunSpace so special? 1. People centric versus  Web centric The main concept of SunSpace put the person in the middle of everything. All relevant information, resources  etc. where dynamically pushed to a person's  myProfile ( Facebook like interface) based on the person's interest and  needs.  2. Ease to use  SunSpace was really easy to use. We spent a lot of time on social interaction design to optimize the user experience.  Also we integrated some sophisticated technology to hide complexity from the user. As example - when a user added a document to SunSpace - we analyzed the content of the document and suggested related metadata and tags to the user based on a sophisticated algorithm which was integrated with the corporate taxonomy. Based on this metadata the document was automatically shared with the relevant communities.  3. Easy to find One of the main use cases for SunSpace was that  a user could quickly find the content and information they needed for their job.  The search implementation was based on:  optimized search engine algorithm using social value based ranking enhancements community facilitated search optimization  faceted search which recommended highly relevant  content like products, communities and experts 4. Social Adoption  - How to build vibrant communities You can deploy the coolest social technology but what if the users are not using it?   To drive user adoption we implemented two  complementary models: 4.1 Community Methodology  We developed a set of best practices on how to create, run and sustain communities including: community structure and types (e.g. Community of Practice, Community of Interest etc.) & tips and tricks on how to build a "vibrant " communities, Community Health check etc.  These best practices where constantly tuned and updated by the community of community drivers. 4.2. Social Value System To drive user adoption there is ONE key  question you  have to answer for each individual user: What's In It For Me (WIIFM) We developed a Social Value System called Community Equity which measures the social value flow between People, Content and Metadata. Based on this technology we added "Gamfication" techniques (although at that time this term did not exist ) to SunSpace to honor people for the active contribution and participation.  As example: All  social credentials a user earned trough active community participation where dynamically displayed on her/his myProfile. How would you describe WebCenter? Oracle WebCenter (@oraclewebcenter) is the Oracle's  user engagement platform for social business. It helps people work together more efficiently through contextual collaboration tools that optimize connections between people, information, and applications and ensures users have access to the right information in the context of the business process in which they are engaged. Oracle WebCenter can help your organization deliver contextual and targeted Web experiences to users and enable employees to access information and applications through intuitive portals, composite applications, and mash-ups. How does it compare to SunSpace in terms of functionality? Before I answer this question, I would like to point out some limitation we started to see with the current SunSpace implementation. Due to the massive growth of the user population (>20,000 users), we experienced  performance and scalability challenges with the current technology. Also at the time - Sun Internal Communications and SunIT planned to replace the entire Sun Intranet with SunSpace. We  kicked-off a project to evaluate the enterprise level technology which eventually would replace the good old static Intranet.  And then Oracle acquired Sun. We already had defined the functional requirements for the Intranet replacement with a Social Enterprise Stack and we just needed to evaluate the functional requirements against WebCenter   Below are the summary of this evaluation  MyProfile SunSpace WebCenter How WebCenter Works Home MyProfile: to access, click on your name at the top of any WebCenter page Your name, title, and reporting line are displayed.  Sub-tabs show your activity stream (Activities); people in your network (Connections); files you have uploaded (Documents); your contact information (Organization); and any personal information you wish to share (About).   Files MyFiles Allows you to upload, download and store documents or wiki pages within folders and subfolders.  The WebDav interface allows you to download / upload files / folders with a simple drag and drop to / from your local machine.  Tagging is supported and recommended. Network HomeMyConnections Home: displays the activity stream of individuals in your network.MyConnections: shows individuals in your network.  Click on a person's name to see their contact info and link to their profile. Status Updates MyProfle > Activties Add and displays  your recent activties and status updates. Watches Preferences > Subscriptions > Current Subscriptions Receive email notifications when  pages / spaces you watch are modified. Drafts N/A WebCenter does not support Drafts Settings Preferences: to access, click on 'Preferences' at the top of any WebCenter page Set your general preferences, as well as your WebCenter messaging, search and mail settings. MyCommunities MySpaces: to access, click on 'Spaces' at the top of any WebCenter page Displays MySpaces (communities you are a member of); and Recent Spaces (communities you have recently visited). Community SunSpace Webcenter How Webcenter Works Home Home Displays a community introduction and activity stream.  Members can add messages, links or documents via the Community Message Board. No Top Contributors widget. People Members Lists members of the community. The Mail All Members feature allows moderators and participants to send a message to all members of the community. Membership Management can be found under > Manage > Members News News Members can post and access latest community news and they can subscribe to news using an RSS reader Documents Documents Allows community members to upload, download and store documents or wiki pages within folders and subfolders.  The WebDav interface allows participants to download / upload files / folders with a simple drag and drop to / from your local machine.  Tagging is supported and recommended. Wiki Wiki Allows community members to create and update web pages with a WYSIWYG editor.  Note: WebCenter does not support macros or portlet embedding. Forum Forum Post community forum topics. Contribute to community forum conversations.  N/A Calendar Update and/or view the Community Calendar. N/A Analytics Displays detailed analytics data (views,downloads, unique users etc.) for Pages, Wiki, Documents, and Forum in a given community space. What is the adoption of WebCenter at Oracle? The entire Intranet serving around 100,000 users  is running on WebCenter Content.  For professional communities we use WebCenter Portal and Spaces. Currently we have around 6,000 community spaces with  around 40,000 members.  Does Oracle have any metrics to assess usage and impact of WebCenter? Can you give us some examples? Sure -  we have a lot of metrics   For the Intranet we use traditional metrics like pageviews, monthly unique visitors and unique visits.  For Communities we use the WebCenter Portal/Spaces analytics service which gives as a wealth of data. The key metrics we track are: Space traffic (PageViews, Unique Users) Wiki,Documents (views, downloads etc.) Forum (users, views, posts etc.) Registered members over time  Depending on the community we can filter/segment the metrics by User Properties e.g. Country, Organization, Job Role etc. What are you doing to improve usage and impact? 1. We  integrating the WebCenter social services/fabric into all  main business applications. As example The Fusion CRM deployment is seamless integrated with Oracle Social Network (OSN) and all conversation around an opportunity or customer engagement is  done in OSN (see youtube video). 2. We drive Social Best Practice trough a program called "Social Networking & Business Collaboration (SNBC) program" You worked both with WebCenter and SunSpace. Knowing what you know today, if you had the chance to choose between the two, which one would you choose? Why? That's a tricky question   In the early days of  the Social Enterprise implementation (we started SunSpace in 2006), we needed an agile and easy to deploy technology to keep up with the users requirements. Sometimes we pushed two releases per day  and we were in a permanent perpetual beta mode - SunSpace was perfect for that.  After the social implementation matured over time - community generated content became business critical and we saw a change in the  requirements from agile to stability, scalability and reliability  of the infrastructure.  WebCenter is the right choice for such an enterprise-level deployment.  You are a WebCenter Evangelist at Oracle. What do you do as part of that role? Our  role is to help position Oracle as one of the key thought leaders and solutions provider for Social Business. In addition we drive social innovation trough our Oracle Appslab  team. Is that a full time role? Yes  How many other Evangelists are there in Oracle? We are currently 5 people in the WebCenter evangelist team (@webcentervoices): Christian Finn (@cfinn) leads the team - Christian came from the Microsoft Sharepoint product management team and is a recognized expert in Social Business and Enterprise Collaboration. Noël Jaffré  (@noeljaffre) is our Web Experience Management (WEM) guru and came to Oracle via FatWire acquisition (now WebCenter Sites). Jake Kuramoto (@theapplab) is part of the Oracle AppsLab innovation  team - Jake is well known as  the driving force behind  http://theappslab.com  a blog around social and innovation.  Noel Portugal (@noelportugal) is a developer in the Oracle AppsLab innovation team - he is the inventor of OraTweet - Oracle's internal tweeting platform  Peter Reiser (@peterreiser) is  a Social Business guru and the inventor of SunSpace and Community Equity.  What area of the business do you and the rest of the Evangelists sit in? What area of the organisation is responsible for WebCenter? We are part of the WebCenter product management  organization.  Is WebCenter part of the Knowledge Management strategy? Oracle WebCenter is the Oracle's user engagement platform for social business. It brings together the most complete portfolio of portal, web experience management, content, social and collaboration technologies into a single product suite and is the product foundation of the Oracle Knowledge Management strategy.  I am aware Oracle also uses Beehive internally. How would you describe Beehive? Oracle Beehive provides an integrated set of communication and collaboration services built on a single scalable, secure, enterprise-class platform Beehive is  internally used for enterprise wide mail, calendar and real collaboration (Web conferencing) services.  Are Beehive and WebCenter connected? Historically Beehive and WebCenter Portal & Content had some overlap in functionally. (Hey - if  a company has an acquisition strategy to strengthen its product offering and accelerate  innovation, it's pretty normal that functional overlap exists  :- )) A key objective of the WebCenter strategy is  to combine all social and collaboration offerings under the WebCenter product family. That means that certain Beehive components  will be integrated into the overall WebCenter product offering.  Are there any other internal collaboration tools at Oracle? Which ones There here are two other main social tools which are widely used at Oracle  Oracle Connect was the first social tool the Oracle AppsLab team created in 2007 - see (Jake's blog post for details). It is still extensively used. ... and as a former Sun guy I like this quote from the blog post:  "Traffic to Connect peaked right after the Sun merger in 2010, when it served several hundred thousand pageviews each month; since then, traffic has subsided, but still averages tens of thousands of pageviews to several thousand users each month." Oratweet - Oracle internal microblogging platform has been used since June 2008 and it is still growing.  It's entirely written in Oracle Application Express (APEX) which is a rapid web application development tool for the Oracle database. Wanna try it out? Here you can download the code.  What is Oracle's strategy regarding (all these) collaboration tools? Pretty straight forward. The strategy is to seamless  integrate the WebCenter social & collaboration services into all Business Applications to help customers to socialize their enterprise.

  • Setting ProcessStartInfo.WorkingDirectory to an UNC Path

    - by TJOHN
    I have a utility that I have written in VB.net that runs as a scheduled tasks. It internally calls another executable and it has to access a mapped drive. Apparently windows has issues with scheduled tasks accessing mapped drives when the user is not logged on, even when the authentication credentials are supplied to the task itself. Ok, fine. To get around this I just passed my application the UNC path. process.StartInfo.FileName = 'name of executable' process.StartInfo.WorkingDirectory = '\\unc path\' process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden process.StartInfo.Arguments = 'arguments to executable' process.Start() This is the same implementation I used with the mapped drive, however using the UNC path, the process is not behaving as if the UNC path is the working directory. Are there any known issues setting ProcessStartInfo.WorkingDirectory to an UNC path? If not, what am I doing wrong?

  • XCOPY to remote server

    - by Max
    In order to improve the deployment / build process of my ASP.NET app, I would like to make a .bat that builds the current solution in release mode xcopy the files to a remote server Creating a release build via command line is easy. But how can I xcopy the files to the remote server? I think I have to map the remote destination to a network drive (?). However I could not connect to the remote server, although I have enabled file sharing for the folder on the server. Maybe the firewall is blocking the request? Which port should I open? Or is there another solution? EDIT Thanks for all the answers so far, but I probably need a step by step guide on how to set up the folder sharing on the server. I shared the folder, I opened up port 445 so that I can connect to the server but still, I cant connect from my local machine to the server in order to map the network path to a system drive.
