• Networking Guidelines

  - by ACShorten

  One of the things I have noticed in my years in IT is the changes in networking. In the past networking was pretty simple with the host name and name resolution (via DNS) being pretty simple. Some sites still use this simple networking setup. These days, more complex name resolution, proxies, firewalls, demarcation nd virtualization, can make networking more complex. This can cause issues when installing products with in built networking that can frustrate even seasoned veterans. I have put together a few basic guidelines to hopefully help along with product installation and getting a product to operate in a somewhat complex network setup. All the components of the product (including the infrastructure) need to communicate via a network (even it is within a local machine/host). Ensure any host names referred to within configuration files are accessible via your networking setup. This may mean defining the hosts to the machines, to the DNS for name resolution and even your firewall to allow machines to communicate within your network. Make sure the ports used for any of the infrastructure are accessible (even through your firewall) and are unique within the host. Host duplication can cause the product to fail on startup as the port is already in use. If there are still issues, consider using localhost as your host name. I have used this in so many situations that I tend to use it now as a default anytime I install anything myself. Most Oracle products suggest to use localhost when using dynamic host or dynamic IP addresses and this is no different for the Oracle Utilities Application Framework. If you do use localhost then installing a Loopback Adapter for the operating system is recommended to force networking to a minimum. Usually localhost resolves to 127.0.0.1. When using multiple network connections, especially in a virtualized environment, ensure the host and ports used are relevent for the network cards you have setup. One of the common issues is finding the product is using a vierualized network card only to find that it is not setup for correct networking. If you are using the batch component, do not forget to ensure that the multicast protocol is enabled on your host and that the multicast address and port number specified are valid and accessible from all machines in the batch cluster (if clustering used). The same advice applies if you are using unicast where each host/port combination should be accessible. Hopefully these basic networking recommendations will help minimize any networking issues you might encounter.

• Do you care about your Oracle System Support experience?

  - by user12244613

  It has been a while since I blogged about Systems Support within Oracle. I want to take this opportunity to raise awareness of how Oracle is communicating out to its systems customers. Previously every item to be communicated was sent independently via an email message however, not all messages appear to be being getting the attention they require. In an effort to ensure Oracle is reaching all of our Sun and Oracle System customers, we have created the Oracle Systems Support Newsletter. This monthly newsletter will have a summary of customer support relevant information for you to use and will cover topics that impact your support experience. For example: 1. Did you know that sending explorer content to email addresses with @sun.com is going away soon? For more information, review the Document 1362484.1 2. Are you an Auto Service Request (ASR) user? If yes, here are the latest changes: · ASR Manager accepts My Oracle Support User Name (email address) and password. [Doc ID 1345484.1] · ASR IP Address for secure file transfer has changed [Doc ID 1338575.1] · ASR No Heartbeat Status - Find out how to resolve [Doc ID 1346328.1] 3. Did you notice we have changed the Service Request options for Hardware and introduced a new problem category called “Automated Diagnosis”? This service streamlines the data you send in and then automatically provides an update of known issues found in your My Oracle Support Service Request. This feature also fast tracks hardware failures by sending parts as soon as the data is analyzed. Have you used this new feature? If yes tell us about it – take the 5minute survey 4. Are you being proactive or are you still ‘fire fighting’ in the reactive mode? If you are being proactive for your Oracle System products you might have used Oracle Sun System Analysis. Did you finding this helpful? Can we improve it? You tell us, take the 5minute survey 5. Are you aware that if you attach files to your Service Request it enables the support engineer to start work straight away? For a summary of products and files review the Newsletter. 6. Are you struggling to find patches or firmware or product downloads? If yes, these types of issues are all addressed in the Newsletter. If this is the type of information you want to know about each month, then take time to read the Newsletter link and bookmark it in My Oracle Support so you can stay informed. Thanks for your time.

• Wifi disabled for Intel Centrino Wireless-N 1000 Intel in 12.04

  - by new_bie

  Laptop model - HP- dm4 - 2070. I had faced the same problem for wireless being disabled in case of 11.10. It had to do with the new kernel. I thought with 12.04 this problem will be handled but the problem persists. Is there no way to get the wireless working except for the way mentioned in the following link ??

• Suggestions for connecting .NET WPF GUI with Java SE Server

  - by Sam Goldberg

  BACKGROUND We are building a Java (SE) trading application which will be monitoring market data and sending trade messages based on the market data, and also on user defined configuration parameters. We are planning to provide the user with a thin client, built in .NET (WPF) for managing the parameters, controlling the server behavior, and viewing the current state of the trading. The client doesn't need real-time updates; it will instead update the view once every few seconds (or whatever interval is configured by the user). The client has about 6 different operations it needs to perform with the server, for example: CRUD with configuration parameters query subset of the data receive updates of current positions from server It is possible that most of the different operations (except for receiving data) are just different flavors of managing the configuration parameters, but it's too early in our analysis for us to be sure. To connect the client with the server, we have been considering using: SOAP Web Service RESTful service building a custom TCP/IP based API (text or xml) (least preferred - but we use this approach with other applications we have) As best as I understand, pros and cons of the different web service flavors are: SOAP pro: totally automated in .NET (and Java), modifying server side interface require no code changes in communication layer, just running refresh on Web Service reference to regenerate the classes. con: more overhead in the communication layer sending more text, etc. We're not using J2EE container so maybe doesn't work so well with J2SE REST pro: lighter weight, less data. Has good .NET and Java support. (I don't have any real experience with this, so don't know what other benefits it has.) con: client will not be automatically aware if there are any new operations or properties added (?), so communication layer needs to be updated by developer if server interface changes. con: (both approaches) Server cannot really push updates to the client at regular intervals (?) (However, we won't mind if client polls the server to get updates.) QUESTION What are your opinions on the above options or suggestions for other ways to connect the 2 parts? (Ideally, we don't want to put much work into the communication layer, because it's not the significant part of the application so the more off-the-shelf and automated the better.)

• Can't get Wireless RT2x00usb driver to work, and can't blacklist it

  - by TheLQ

  After a two year hiatus to Linux, I try it again out again. And then I run into to driver issues... I have an old Linksys WUSB54G v4 Wireless USB Adapter. In previous versions I had to use a combination of Ndiswrapper and Wicd to hope of getting it working. In 10.10, apparently there are built in drivers for it. Unfortunately they don't work. Fails to connect to my WPA network, fails to connect to my open unencrypted network. Wicd fails at "Obtaining IP address" or when using static IPs fails at verifying connectivity to network. Getting fed up I tried the ndiswrapper approach. Installed and configured, but still not working, even when blacklisting the rt2570 module. So for some debugging I added some lines to my /etc/modprobe.d/blacklist.conf file blacklist rt2570 blacklist prism54usb blacklist rt2x00lib blacklist rt2x00usb Restart and find this: lordquackstar@quackbeast:/etc/modprobe.d$ lsmod | grep rt2 rt2500usb 18049 0 rt2x00usb 9779 1 rt2500usb rt2x00lib 27275 2 rt2500usb,rt2x00usb led_class 2633 1 rt2x00lib mac80211 231541 2 rt2x00usb,rt2x00lib cfg80211 144470 2 rt2x00lib,mac80211 Seems to be ignored...

Restarted and was back to the same modules loading.

• Suggestions for connecting .NET WPF GUI with Java SE Server aoo

  - by Sam Goldberg

  BACKGROUND We are building a Java (SE) trading application which will be monitoring market data and sending trade messages based on the market data, and also on user defined configuration parameters. We are planning to provide the user with a thin client, built in .NET (WPF) for managing the parameters, controlling the server behavior, and viewing the current state of the trading. The client doesn't need real-time updates; it will instead update the view once every few seconds (or whatever interval is configured by the user). The client has about 6 different operations it needs to perform with the server, for example: CRUD with configuration parameters query subset of the data receive updates of current positions from server It is possible that most of the different operations (except for receiving data) are just different flavors of managing the configuration parameters, but it's too early in our analysis for us to be sure. To connect the client with the server, we have been considering using: SOAP Web Service RESTful service building a custom TCP/IP based API (text or xml) (least preferred - but we use this approach with other applications we have) As best as I understand, pros and cons of the different web service flavors are: SOAP pro: totally automated in .NET (and Java), modifying server side interface require no code changes in communication layer, just running refresh on Web Service reference to regenerate the classes. con: more overhead in the communication layer sending more text, etc. We're not using J2EE container so maybe doesn't work so well with J2SE REST pro: lighter weight, less data. Has good .NET and Java support. (I don't have any real experience with this, so don't know what other benefits it has.) con: client will not be automatically aware if there are any new operations or properties added (?), so communication layer needs to be updated by developer if server interface changes. con: (both approaches) Server cannot really push updates to the client at regular intervals (?) (However, we won't mind if client polls the server to get updates.) QUESTION What are your opinions on the above options or suggestions for other ways to connect the 2 parts? (Ideally, we don't want to put much work into the communication layer, because it's not the significant part of the application so the more off-the-shelf and automated the better.)

• Is it a bug or a task when something doesn't work, yet, in development process

  - by Patkos Csaba

  We usually have this dilemma in our team. Sometimes, in order to implement a task or a story we find out that the system must be in a specific state. For example, a specific system configuration has to be made beforehand. The task / story can be completed and it is working as specified on it with the proper configuration in place. Note that the configuration is not directly related with the task. Next, we have to create a new ... ??? ... something for the process of generating that configuration file. This is where the problems appear. Some say that it is a bug others say it is a task or an extra feature. So, where is the limit between bugs and tasks in the development phase? Should we even consider something a bug if all the tasks are working as stated in their definitions? Can a thing be considered a bug because one compares it to the current (unstable) state of the system? Short example: A feature requires configuring a communication service for a specific operation. In the process of the implementation the team discovers that the service requires the hostnames of the pears to be resolvable to an IP address. The team adds the hostnames to the DNS server (or hosts files) and continues implementing the required feature. After the initial feature is working, a question is risen. Should the sysadmin configure the DNS or hosts file or should our application do it automatically? An automatic solution is possible. So a decision is made to implement it. ... here start the discussions ... is this a bug or an extra feature / task? PS: I know that I mixed feature / task / story in the question. It is intentional. I am interested in separating bugs from the rest. Doesn't matter what the rest means in a particular case.

• Is Infiniband going to get squeezed by iWARP and external QPI?

  - by andy.grover

  The Inquirer certainly thinks so.However, I'm not so sure it makes sense to compare Infiniband to an as-yet-unannounced optical external QPI. QPI is currently a processor interconnect. CPUs, RAM, and devices connected by it are conceptually part of the same machine -- they run a single OS, for example. They are both "networks" or "fabrics" but they have very different design trade-offs.Another widely-used bus in the system is closer to Infiniband than QPI -- PCI Express. Isn't it more likely that PCIe could take on IB? There are companies already who have solutions that use external PCI Express for cluster interconnect, but these have not gained significant market share. Why would QPI, a technology whose sweet spot is even further from Infiniband's than PCIe, be able to challenge Infiniband? It's hard to speculate without much information, but right now it doesn't seem likely to me.The other prediction made in the article is that Intel's 10GbE iWARP card could squeeze IB on the low end, due to its greater compatibility and lower cost.It's definitely never a good idea to bet against Ethernet when it comes to mass-market, commodity networking. Ethernet will win. 10GbE will win. But, there are now two competing ways to implement the low-latency RDMA Verbs interface on top of Ethernet. iWARP is essentially RDMA over TCP/IP over Ethernet. The new alternative is IBoE (Infiniband over Ethernet, aka RoCEE, aka "Rocky"). This encapsulates the IB packet protocol directly in the Ethernet frame. It loses the layer 3 routability of iWARP, but better maintains software compatibility with existing apps that use IB, and is simpler to implement in both software and hardware. iWARP has a substantial head start, but I believe that IBoE silicon will eventually be cheaper, and more likely to be implemented in commodity Ethernet hardware.I think IBoE is going to take low-end market share from traditional IB, but I think this is a situation IB hardware vendors have no problem accepting. Commoditized IBoE NICs invite greater use of RDMA features, and when higher performance is needed, customers can upgrade to "real" IB, maintaining IB's justification for higher prices. (IB max interconnect speeds have historically been 2-4x higher than Ethernet, and I don't see that changing.)(ObDisclosure: My current employer now sells IB hardware. I previously also worked at Intel. My opinions are my own, duh.)

• New Oracles VM RAC template with support for oracle vm 3 built-in

  - by wcoekaer

  The RAC team did it again (thanks Saar!) - another awesome set of Oracle VM templates published and uploaded to My Oracle Support. You can find the main page here. What's special about the latest version of DeployCluster is that it integrates tightly with Oracle VM 3 manager. It basically is an Oracle VM frontend that helps start VMs, pass arguments down automatically and there is absolutely no need to log into the Oracle VM servers or the guests. Once it completes, you have an entire Oracle RAC database setup ready to go. Here's a short summary of the steps : Set up an Oracle VM 3 server pool Download the Oracle VM RAC template from oracle.com Import the template into Oracle VM using Oracle VM Manager repository - import Create a public and private network in Oracle VM Manager in the network tab Configure the template with the right public and private virtual networks Create a set of shared disks (physical or virtual) to assign to the VMs you want to create (for ASM/at least 5) Clone a set of VMs from the template (as many RAC nodes as you plan to configure) With Oracle VM 3.1 you can clone with a number so one clone command for, say 8 VMs is easy. Assign the shared devices/disks to the cloned VMs Create a netconfig.ini file on your manager node or a client where you plan to run DeployCluster This little text file just contains the IP addresses, hostnames etc for your cluster. It is a very simple small textfile. Run deploycluster.py with the VM names as argument Done. At this point, the tool will connect to Oracle VM Manager, start the VMs and configure each one, Configure the OS (Oracle Linux) Configure the disks with ASM Configure the clusterware (CRS) Configure ASM Create database instances on each node. Now you are ready to log in, and use your x node database cluster. x No need to download various products from various websites, click on trial licenses for the OS, go to a Virtual Machine store with sample and test versions only - this is production ready and supported. Software. Complete. example netconfig.ini : # Node specific information NODE1=racnode1 NODE1VIP=racnode1-vip NODE1PRIV=racnode1-priv NODE1IP=192.168.1.2 NODE1VIPIP=192.168.1.22 NODE1PRIVIP=10.0.0.22 NODE2=racnode2 NODE2VIP=racnode2-vip NODE2PRIV=racnode2-priv NODE2IP=192.168.1.3 NODE2VIPIP=192.168.1.23 NODE2PRIVIP=10.0.0.23 # Common data PUBADAP=eth0 PUBMASK=255.255.255.0 PUBGW=192.168.1.1 PRIVADAP=eth1 PRIVMASK=255.255.255.0 RACCLUSTERNAME=raccluster DOMAINNAME=mydomain.com DNSIP= # Device used to transfer network information to second node # in interview mode NETCONFIG_DEV=/dev/xvdc # 11gR2 specific data SCANNAME=racnode12-scan SCANIP=192.168.1.50

• Ubuntu Server Cannot Route to the Internet

  - by ejes

  I've been having this problem for weeks now, and I can't seem to figure out the problem. My server can route the local network and serves it well, however it cannot access the internet. It can't be the router because everything else on this lan can route through the router. I've even switched the ethernet port. Any help would be appreciated. I've tried all the usual places, anyway, here are the configs: root@uhs:~# uname -a Linux uhs 3.0.0-16-generic-pae #28-Ubuntu SMP Fri Jan 27 19:24:01 UTC 2012 i686 i686 i386 GNU/Linux root@uhs:~# cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.

• WiFi connected to router, but no internet connection

  - by Quetzacotl

  I just got a new notebook, a ThinkPad Edge E530, and installed Ubuntu on it. I'm pretty new to Ubuntu. On the same laptop, running Windows 7, the Wi-Fi connection works fine. Ethernet connection works both on Win7 and on Ubuntu. Only Wi-Fi on Ubuntu does not work; it connects to the Wi-Fi access point but I don't have Internet access. My wireless card is Intel Centrino Wireless-N 2230. What can fix the problem?

• No client internet access when setting up these iptables rules

  - by Siriss

  I have read many other posts but cannot figure this out. eth0 is my external connected to a Comcast modem. The server has internet access with no issues. eth1 is internal and running DHCP for the clients. I have DHCP working just fine, all my clients can get an IP and ping the server but they cannot access the internet. I am using ISC-DHCP-SERVER and have set /etc/default/isc-dhcp-server to INTERFACE="eht1" Here is my dhcpd.conf file located in /etc/dhcp/dhcpd.conf ddns-update-style interim; ignore client-updates; subnet 10.0.10.0 netmask 255.255.255.0 { range 10.0.10.10 10.0.10.200; option routers 10.0.10.2; option subnet-mask 255.255.255.0; option domain-name-servers 208.67.222.222, 208.67.220.220; #OpenDNS # option domain-name "example.com"; default-lease-time 21600; max-lease-time 43200; authoritative; } I have made the *net.ipv4.ip_forward=1* change in /etc/sysctl.conf here is my interfaces file: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp iface eth1 inet static address 10.0.10.2 netmask 255.255.255.0 network 10.0.10.0 auto eth1 And finally- here is my iptables.conf file: # Firewall configuration written by system-config-firewall # Manual customization of this file is not recommended. *nat :PREROUTING ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] -A POSTROUTING -s 10.0.10.0/24 -o eth0 -j MASQUERADE #-A PREROUTING -i eth0 -p tcp --dport 59668 -j DNAT --to-destination 10.0.10.2:59668 COMMIT *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -i eth1 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 53 -j ACCEPT -A INPUT -m state --state NEW -m udp -p udp --dport 53 -j ACCEPT -A FORWARD -s 10.0.10.0/24 -o eth0 -j ACCEPT -A FORWARD -d 10.0.10.0/24 -m state --state ESTABLISHED,RELATED -i eth0 -j ACCEPT -A FORWARD -p icmp -j ACCEPT -A FORWARD -i lo -j ACCEPT -A FORWARD -i eth1 -j ACCEPT #-A FORWARD -i eth0 -m state --state NEW -m tcp -p tcp -d 10.0.10.2 --dport 59668 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT I am completely stuck. I cannot figure out why the clients cannot access the internet. Am I missing a service? Is a service not running? Any help would be greatly appreciated. I tried to be as thorough as possible but please let me know if I have missed something. Thank you!

• Using Network load balancing to distribute load for SharePoint2010 – Part3 of building my own development SharePoint2010 Farm

  - by ybbest

  Part1 of building my own development SharePoint2010 Farm Part2 of building my own development SharePoint2010 Farm Part3 of building my own development SharePoint2010 Farm In my last post, I have installed SharePoint2010 in one of the server (WFE One) and configured using the OOB SharePoint configuration wizard. In this post I will show you how to use OOB windows network load balancing to distribute load for SharePoint2010 site. 1. Install SharePoint in another server WFE Two (you can follow the steps in my last post), but instead of choosing create new Farm, you need to select “connect to existing farm” this time. 2. Click next then click retrieve database names button and select the farm configuration database. 3. Click next and enter the passphrase you specified when you first installed the SharePoint Farm. 4. Click the advanced settings and select Use this machine to host the web site. 5. Click OK to finish the configurations 6. Next, Install NLB in the two WFE (web front end) SharePoint servers 7. Configure NLB to create the cluster. Go to Start—Administrative Tools—Network Load Balancing Manager 8. Right-click the Network Load Balancing Clusters Node and select New Cluster. 9. Type in the host name that is to be part of the new cluster. 10. Type in the IP address for the cluster. 11. Select the Multicast for this cluster.(The default one is Unicast) 12. You can configure the Port Rules for the clustering , but I will leave the default here. 13. Add another WEF to the cluster. 14. Type in the host name that is to be part of the new cluster. 15. Set the Priority to 2. 16. Click Next to complete the cluster setup. 17. Create an entry in the DNS for the new cluster. 18. Add the binding to the IIS site in the IIS Manager 19. Change the Alternate access mapping for you default site collection from http://sp2010wefone to http://team 20. Browse to http://Team , you will be redirected to the SharePoint site.

• Reading a ZFS USB drive with Mac OS X Mountain Lion

  - by Karim Berrah

  The problem: I'm using a MacBook, mainly with Solaris 11, but something with Mac OS X (ML). The only missing thing is that Mac OS X can't read my external ZFS based USB drive, where I store all my data. So, I decided to look for a solution. Possible solution: I decided to use VirtualBox with a Solaris 11 VM as a passthrough to my data. Here are the required steps: Installing a Solaris 11 VM Install VirtualBox on your Mac OS X, add the extension pack (needed for USB) Plug your ZFS based USB drive on your Mac, ignore it when asked to initialize it. Create a VM for Solaris (bridged network), and before installing it, create a USB filter (in the settings of your Vbox VM, go to Ports, then USB, then add a new USB filter from the attached device "grey usb-connector logo with green plus sign")  Install a Solaris 11 VM, boot it, and install the Guest addition check with "ifconfg -a" the IP address of your Solaris VM Creating a path to your ZFS USB drive In MacOS X, use the "Disk Utility" to unmount the USB attached drive, and unplug the USB device. Switch back to VirtualBox, select the top of the window where your Solaris 11 is running plug your ZFS USB drive, select "ignore" if Mac OS invite you to initialize the disk In the VirtualBox VM menu, go to "Devices" then "USB Devices" and select from the dropping menu your "USB device" Connection your Solaris VM to the USB drive Inside Solaris, you might now check that your device is accessible by using the "format" cli command If not, repeat previous steps Now, with root privilege, force a zpool import -f myusbdevicepoolname because this pool was created on another system check that you see your new pool with "zpool status" share your pool with NFS: share -F NFS /myusbdevicepoolname Accessing the USB ZFS drive from Mac OS X This is the easiest step: access an NFS share from mac OS Create a "ZFSdrive" folder on your MacOS desktop from a terminal under mac OS: mount -t nfs IPadressofMySoalrisVM:/myusbdevicepoolname  /Users/yourusername/Desktop/ZFSdrive et voila ! you might access your data, on a ZFS USB drive, directly from your Mountain Lion Desktop. You might play with the share rights in order to alter any read/write rights as needed. You might activate compression, encryption inside the Solaris 11 VM ...

• Will you share your SQL Server configuration?

  - by Bill Graziano

  I regularly visit client sites and review their SQL Server configurations.  I come across all kinds of strange settings.  I’ve been thinking about a way to aggregate people’s configurations and see what’s common and what’s unique.  I used to do that with polls on SQLTeam.com.  I think we can find out more interesting things if we look at combinations of settings in relation to size and volume. I’ve been working on an application for another project that is similar.  It will be fairly easy to use that code for this.  I can have something up and running in a few days – if people are interested in it.  I admit that I often come up with ideas that just don’t make sense.  This may be one of them.  One of your biggest concerns has be how secure your data is.  My solution is not to store anything identifying.  The instance name and database names can both be “anonymized” and I don’t store the machine name or IP address or anything to do with logins. Some of the questions I’m curious about are: At what size database does the Enterprise Edition become prevalent? Given the total size of the databases how much RAM is common? How many people have multiple data files?  At what size does that become prevalent? How common is database mirroring?  Replication?  Log shipping? How common is full recovery mode?  At what data size does it become prevalent? I think those are all questions that are easy to answer -- with the right data.  The big question is whether or not people will share their SQL Server configurations.  I understand that organizations in regulated or high security environments can’t participate.  But I think that leaves many, many people that can.  Are you willing to share your configuration and learn about others?  I have a simple sign up form here.  It’s actually a mailing list signup that also captures your edition, number of servers and largest database.  The list will only be used for this project.  Is your SQL Server is configured correctly?  Do you wonder what the next step is as your data grows?  Take a second and sign up.

• Best way to remote restart Ubuntu from Windows machine

  - by robsoft

  Background: I'm looking to put a series of Ubuntu machines into retail locations, they're being used as dumb kiosks to show a series of slides onto large LCD panel TV screens. Once installed, they won't have a keyboard or mouse connected but will have a fixed IP on the local network. Everything is configured to auto-start, no automatic updates, no power saving etc - I think we're pretty-much good to go apart from one thing. I need the retail staff to be able to restart the boxes if a problem arises. We have VNC running (now that we've turned off desktop enhancements!) so that we can remotely get into the machines if we need to, but that's not something we would allow the retail staff to do. The machines are going to be physically 'out of the way' (probably in the ceiling space) so the power button is not easily accessible!. I'd like to have some means of allowing the retail staff to restart the Ubuntu machine, from the desktop of one of their Windows terminals. I don't really want to give them some kind of raw terminal access (the command line will frighten them!) and I don't want them to use VNC (as stated above). Ideally there would be an icon on the Windows desktop, they double-click it, reply to a simple 'are you sure?' prompt, and then the Ubuntu box is told to restart. The Windows side of that won't be a problem, we can write something using Delphi, Python & Qt4, whatever - it's the Ubuntu side of it I'm stuck with. Out of sight/view, could I have a Windows program open a terminal across the network and tell Ubuntu to restart? Is this what SSH could be used for (I have never set that kind of thing up). The Windows programming side isn't really an issue, it's just that I'm a total Ubuntu noob and don't know where to start from the platform point of view. The other thing we considered is also having the machine automatically restart itself at a set time each day (obviously out of store hours!). To me, that seems a bit unnecessary (though forcing a restart once a week/month might be worthwhile). Any thoughts or suggestions? Being able to restart the box on demand across the network is my prime requirement.
