  • Oracle Solaris 11.1 Announced at Oracle OpenWorld

    - by glynn
    One of the highlights for me at Oracle OpenWorld was our announcement of the next update version to Oracle Solaris 11, named Oracle Solaris 11.1. Since November 2011, we've done a lot of work not only to polish existing features and fix literally hundreds of bugs, but also add many new features that give yet more reasons for using Oracle Solaris as the deployment platform for Oracle workloads - particularly the Oracle database. Over the last few years since the Sun Microsystems acquisition, we've had our developers sitting in Redwood Shores with the Oracle database team figuring out how to best optimize that combination and provide a level of integration that no other vendor (or solution) can match. Oracle Solaris 11.1 is often the first release many customers will adopt due to perceived instability of '.0' releases. In reality, however, we've seen incredible adoption already and all our existing customers are loving the new technologies like Image Packaging System (IPS), Automated Installer and ZFS Boot Environments, consolidated network management and network virtualization, and of course the existing features that are so critical to creating private, hybrid or public cloud environments like the Oracle Solaris ZFS file system and Oracle Solaris Zones server virtualization. If you haven't already gotten on board, there's plenty chance to catch up. More importantly, Oracle Solaris 11.1 really provides a platform that is significantly easier to manage than any previous Solaris releases - to the extent that it should be relatively straightforward for any experienced Linux administrator to get up to speed (if they're struggling, we have ways to help). So take a look at what's new in Oracle Solaris 11.1 and start planning your deployment now! If you missed the announcement, you can see the full video of John Fowler's keynote at Oracle OpenWorld here:

  • How to automate an Amazon EC2 instance startup, execution of some commands and shutdown?

    - by Howiecamp
    I need to download 100 GB of files (it’s in about 150 files) within a 7 day period before they expire. The download is rate-limited by the host so it takes MUCH longer than the theoretical transfer rate based on normal Internet speeds. I have a script of curl http://curl.haxx.se/docs/manpage.html commands - one line per file. I had the idea of automatically spinning up n EC2 instances, executing the command and FTPing the files to a central location, then shutting down the machines. How would I do this? I don't care whether it's Linux or Windows.

  • Amavis-new whitelist

    - by pigeon
    Hi to the Linux community. I'm coming from a Windows Server background so have mercy. I'm attempting to whitelist some domains and although I know this isn't the best way of doing so its just a one off for a couple of domains so I thought it would be the quickest way of doing so. Current setup: Amavis is used to pass emails off the ClamAV and SpamAssasin, currently I make changes in /etc/amavis/conf.d/50-user, as this will overide other settings. Have created a whitelist file that looks like this: .domaintowhitelist.com .domain2towhitelist.com In the 50-user config file: Have tried variants like this: read_hash(\%whitelist_sender, '/etc/amavis/whitelist'); read_hash(\%virus_lovers, '/etc/amavis/whitelist'); And restarting amavis after making those changes. Am I going about this the wrong way? Any help is appreciated.

  • Multiple computers on Ubuntu One

    - by L R Bellmore Jr
    I have added files from 4 computers to Ubuntu One. One computer failed. What happens to the files that I uploaded. Are they still on Ubuntu One? How come when I upload a file from computer A, computer B with the same Ubuntu One account does not sync and load that file into computer B - That has created this question.. what happens to files from computers from which I uploaded documents when those computers are no longer active or failed, or no longer have Ubuntu One on that computer from which the files were uploaded... Have I lost the files? The followup question is how come files from Computer A uploaded to Ubuntu One don't sync to Computer B. That is a related question. I need to shut down a computer, reformat the hard drive and install Linux on the entire harddrive instead of a dual boot with Windows XP as I am going to use Virtual Machines instead.. what happens to the files from the Windows Dual Boot that were uploaded to Ubuntu One? Are they removed from Ubuntu One and then have I lost those files if I don't backup to another service first.

  • Multiple Ubuntu Server SSH Connections

    - by Craig Smith
    I'm trialing a ubuntu server 12.04 LTS to replace a Windows Server that I use but I have got a little stuck with SSH I'm currently able to SSH into the server but I need to have multiple persistent SSH connections as I have at least 3 applications that need to run in the server and still be able to access their terminals to issue commands to the applications. At the moment this is fine if I use the physical terminals of the machine as I can just jump between the three terminals I use but remotely doing this is the issue. As I'm not entirely familiar with this side of linux I'm not sure if this is even possible to do or how to even get around this issue.

  • How do I add a broadcast IP to the loopback interface under os/x using ifconfig when my machine has no network?

    - by bandodeotarios
    I'm new to advanced network administration and I would like to do some testing with UDP broadcasting, so I need a broadcast address on my loopback interface. The machine is offline, in other words, there is no network. How can I accomplish that through ifconfig without having to buy a switch as one user in the comments suggested. In Linux all i have to do is use 127.255.255.255 and broadcasts work fine without any network or any switch. If I have a network i can just use 255.255.255.255, obviously.

  • Better Embedded 2013

    - by Valter Minute
    Originally posted on: http://geekswithblogs.net/WindowsEmbeddedCookbook/archive/2013/07/30/better-embedded-2013.aspx On July 8th and 9th I had a chance to attend and speak at the Better Embedded 2013 conference in Florence. Visiting Florence is always a pleasure, but having a chance to attend to such an interesting conference and to meet Marco Dal Pino, Paolo Patierno, Mirco Vanini and many other embedded developers made those two days an experience to be remembered. I did two sessions, one on Windows Embedded Standard and “PCs” usage in the embedded world and another one on Android for Embedded devices, you can find the slides on the better embedded website: www.betterembedded.it. You can also find slides for many other interesting session, ranging from the .NET microframework to Linux Embedded, from QT Quick to software licenses. Packing many different resources about embedded systems in a conference was not easy but the result is a very nice mix of contents ranging from firmware development to cloud-based systems. This is a great way to have an overview of what’s new or interesting in embedded systems and to get great ideas about how to build your new device. Don’t forget to follow @Better_Embedded on twitter to not miss next year conference! Thanks to the better embedded team for having allowed me to use some of the official pictures in this blog post. You can find a good selection of those pictures (just to experience the atmosphere of the conference) on its Facebook page: http://dvlr.it/DHDB

  • Using tshark to generate traffic logs every X seconds

    - by Sridhar Iyer
    I'm trying to use tshark to maintain a running history of all the packets that are going through an interface, for say 30 seconds. I want it to be human readable. This is a linux machine, and without mucking too much into the netstack source (which I can do if push comes to shove), I was wondering if I can use tshark to this. tshark has a -b duration:10 -b files:2 which I can use to generate a rotating set of 2 files, but I don't know which format it is printing the file in or how to read it.

  • mkisofs - Floppy Image to Disk Image

    - by CommunistPancake
    I'm trying to compile MikeOS on windows. I've successfully (I think) created a floppy (.flp) image of the operating system. I want to convert it to a disk image (.iso) so I can run it in virtual box. I've tried mkisofs -quiet -V 'MIKEOS' -input-charset iso8859-1 -o disk_images/mikeos.iso -b mikeos.flp disk_images/ Which is the command in the Linux build script. It does create an ISO image, but when I try to run in in VirtualBox, I get a black screen. What am I doing wrong? Here's my build script.

    Hi, A friend has managed to set up their new Windows 7 Home Premium Dell Inspiron and forgot the password they have used. I have tried the following password reset software to no avail: UBCD OHPCrack Offline NT Password & Registry Editor *Trinity Kon Boot I have also tried to do a system restore but this asks for the password. The user does not have any data they need to save. Is there anyway I can get access to the restore partition using Linux to create a recovery disk or do I have to purchase a recovery disk from Dell? Any help is greatly appreciated.

  • Wrong perspective is showing in Eclipse plugin project [closed]

    - by Arun Kumar Choudhary
    I am working in Eclipse Modeling Framework (Eclipse plugin development) in my project the tool(project i am working) provides three perspectives. 1.Accelerator Analyst perspective 2.Contract Validation and 3.Underwriter rules Editor...

As all perspective (Class, Id and Name) is define only inside Plugin.XML as it is the task of org.eclipse.ui.perspective that that perspective name should be come forefront.

  • How should I start with Lisp?

    - by Gary Rowe
    I've been programming for years now, working my way through various iterations of Blub (BASIC, Assembler, C, C++, Visual Basic, Java, Ruby in no particular order of "Blub-ness") and I'd like to learn Lisp. However, I have a lot of intertia what with limited time (family, full time job etc) and a comfortable happiness with my current Blub (Java). So my question is this, given that I'm someone who would really like to learn Lisp, what would be the initial steps to get a good result that demonstrates the superiority of Lisp in web development? Maybe I'm missing the point, but that's how I would initially see the application of my Lisp knowledge. I'm thinking "use dialect A, use IDE B, follow instructions on page C, question your sanity after monads using counsellor D". I'd just like to know what people here consider to be an optimal set of values for A, B, C and perhaps D. Also some discussion on the relative merit of learning such a powerful language as opposed to, say, becoming a Rails expert. Just to add some more detail, I'll be developing on MacOS (or a Linux VM) - no Windows based approaches will be necessary, thanks. Notes for those just browsing by I'm going to keep this question open for a while so that I can offer feedback on the suggestions after I've been able to explore them. If you happen to be browsing by and feel you have something to add, please do. I would really welcome your feedback. Interesting links Assuming you're coming at Lisp from a Java background, this set of links will get you started quickly.

  • How to specify file permission when putting a file using OpenSSH sftp command

    - by Adi Roiban
    I am using various SFTP clients for uploading files to an SFTP server and I have a problem with default permission used when putting files. When requesting to put a file, SFTP client like WinSCP or Filezilla will send the SSH_OPEN command without requesting any explicit file permission. On the other side, it looks like the OpenSSH sftp command on Linux (Red Hat and Ubuntu) is pending the SSH_OPEN command together with the '640' mode. How can I configure the OpenSSH command to not explictly set the file mode or how can I configure it to send a mode, other than 640? Many thanks! Update: I checked the OpenSSH sftp client source code and it looks like OpenSSH sftp will always tries to preserve file mode even if -P is not set: http://www.koders.com/c/fidD3B20680F615B33ACCB42398FAAFEE1C007DF942.aspx?s=rsa#L986 To solve this problem I used Putty SFTP client.

  • Copy/Paste (Clipboard like) functionality from a VNC desktop

    - by goldenmean
    I use TightVNC, RealVNC to access the Remote Linux(CentOS,Ubuntu) desktops by running a vncserver on the remote machine. When I connect to those servers from my Windows host: Can I use the Copy/Paste functionality on the VNC client desktop window. i.e. Copy some text on some terminal open inside the VNC client desktop window and paste it into some text file on my local windows machhines and vice-a-versa? I checked TightVNC options but did not see anything. Can it be done by a)Running vncserver on the remote machine with some options or b)By running some configuration on remote machine to enable this. How could I get it done? Also is this kind of Copy/Paste functionality possible in Microsoft Windows Remote Desktop connection/Terminal session protocol?

  • PXE boot very slow when PXE server is virtualbox

    - by sqrtsben
    As I read in questions here and on the Internet, PXE and Virtualbox don't seem to like each other too much. My problem is the following: I have a virtualized machine which hosts the DHCP and PXE server for 10 native clients. They are rebooted roughly every 10 mins and on each reboot, they need to boot a small linux (the initrd is ~4MB). Before, I had a native machine running and booting via PXE was very fast. Now, looking at the output of nload, I only get 500kbit/s whenever one machine is booting. The machines are connected via a GBit switch, so that can't be it. Also, when testing the connection speed to the outside, I have the full bandwidth available. Is VBox just unable to deal with large amounts of UDP packets? Can anyone point me in the right direction here?

  • How to add authentication to ssh dynamic port forwarding?

    - by Aalex Gabi
    I am using ssh as a SOCKS server by running this command on the server: ssh -f2qTnND *:1080 root@localhost There is one problem: anybody can connect to the server and use it's internet connection. Options: To use iptables to filter access to the server, but I connect to the server from various non-statically allocated IP addresses so I would have to edit very frequently those filters which can be annoying. To install a SOCKS server on the remote. Ultimately this is the last option if there is no other simpler way to do it. (I am very lazy) Launching the same command on clients machines. The problem here is that some clients don't run on Linux and it is awkward to set up the tunnel (Windows + Putty). Is there a way to add authentication to a SOCKS server made using ssh? Bonus question: How to add encryption between the client and the server (made using ssh)?

  • What is the best/easiest way to use scripts to analyze network traffic?

    - by yungin
    I'm looking to analyze packets via scripts. I'd like to use something high level. I'm in a mac/linux environment. I'm currently looking at different python+libpcap libraries. Perhaps lua+wireshark too. Maybe tcpdump+bash (but not sure that has a lot of info i can use). I also heard good things about scapy. Not sure. I'm wondering if you have any recommendations? There's quite a few of them out there. What have you found that works best? I'd definitely want something scriptable not something that I need to compile (like c/c++, etc)

  • Simple Workstation Imaging Solution?

    - by user23087
    I need a fairly cheap imaging solution for Windows XP corporate desktops. Ideally, I'd be able to set up a desktop exactly as we want it, create an image, deploy this image to a server, then boot a new desktop to a CD/USB Drive/Network and quickly set up the workstation. Ideally, each computer would also have a unique workstation name. Any ideas? Right now I'm using a custom built Linux DD solution, but it's slow, not network-based, can't image multiple computers at the same time as there's only one copy on a USB drive, and can't uniquely name the computers. Thanks, Will

  • SSH tunnel over http proxy with blocked 443 (SSL)

    - by Evgeny Zhulenev
    Is it possible to create an SSH tunnel over http-proxy when https access is denied? I had such configuration in .ssh\config Host home User root Hostname *my-home-pc-with-ssh-access-allowed* Port 8090 ProxyCommand corkscrew db-isa-01 8080 %h %p ~/.ssh/.corkscrew-db-isa-auth IdentityFile ~/.ssh/id_rsa Where db-isa-01 is my corporate proxy server. Today the admins blocked all https access and allowed it only for few servers on the white list. I used this command to create a tunnel: ssh -D 7070 -o 'GatewayPorts yes' -A -q -g -t root@home and now it doesn't work. As I can understand, that's because our proxy denies all https connections Proxy could not open connnection to ***: Proxy Error ( The specified Secure Sockets Layer (SSL) port is not allowed. Forefront TMG is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. ) P.S. I use Windows 7, and corscskrew with cygwin, so Linux solutions not suitable for me.

  • Problem with tomcat and getLocalHost exception

    - by xain
    I'm running a Linux server named S1 in a "cloud" server, and when tomcat 6.0.24 starts, I get the exception: org.apache.catalina.connector.Connector pause SEVERE: Protocol handler pause failed java.net.UnknownHostException: S1: S1 at java.net.InetAddress.getLocalHost(InetAddress.java:1353) at org.apache.jk.common.ChannelSocket.unLockSocket(ChannelSocket.java:485) Which then leads to: ERROR ehcache.Cache - Unable to set localhost. This prevents creation of a GUID. Cause was: Sjira1: S1 java.net.UnknownHostException: S1: S1 at java.net.InetAddress.getLocalHost(InetAddress.java:1353) at net.sf.ehcache.Cache.<clinit>(Cache.java:143) My hosts file is: 127.0.0.1 localhost localhost.localdomain (valid-ip-address) S1 S1.(valid domain name) ping S1 and S1.(valid domain name) return valid ip address nslookup S1.(valid domain name) returns valid ip address nslookup S1 throws ** server can't find S1: NXDOMAIN Any ideas about how to fix this ? Thanks
