  • Ubuntu with KVM guest VM and broken bridges

    - by MadPsy
    I have an Ubuntu box with a KVM guest VM running. They use bridging so the guest VM attaches to the physical network of its host. The guest VM has 2 NICs in 2 different bridges. First NIC of the VM is tap5 and is in bridge br0 br0 8000.46720f5c572e no eth0.500 tap5 Second NIC of the VM is tap2 and is in bridge br100 br100 8000.76ad2fc96661 no eth0.100 eth0.101 eth0.103 eth0.104 eth0.105 tap2 On the host, br0 has an IP and br100 does not 21: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 46:72:0f:5c:57:2e brd ff:ff:ff:ff:ff:ff inet 192.168.100.4/24 brd 192.168.10.255 scope global br0 inet6 fe80::d6ae:52ff:febe:777/64 scope link valid_lft forever preferred_lft forever On the guest, its eth0 and eth1 interfaces both have IP addresses 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:3e:61:fb:7a:da brd ff:ff:ff:ff:ff:ff inet 192.168.100.6/24 brd 192.168.100.255 scope global eth0 inet6 fe80::23e:61ff:fefb:7ada/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:3e:61:fb:7a:ea brd ff:ff:ff:ff:ff:ff inet 172.16.50.129/25 brd 172.16.50.255 scope global eth1 inet6 fe80::23e:61ff:fefb:7aea/64 scope link valid_lft forever preferred_lft forever On the guest VM, a tcpdump of its eth1 interface (tap2) shows traffic from its eth0 interface (tap5), as if the 2 bridges are themselves bridged. This means any interface on br100 is now bridged across to br0 - which is completely broken. root@chillispot:~# tcpdump -c 1 -n -v -i eth1 net 192.168.100.0/24 tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 16:31:24.175583 IP (tos 0x0, ttl 64, id 48054, offset 0, flags [DF], proto TCP (6), length 148) 192.168.100.6.22 > 192.168.100.4.59505: Flags [P.], cksum 0x6c2b (correct), seq 1056321648:1056321744, ack 398642983, win 1700, options [nop,nop,TS val 197473436 ecr 200655363], length 96 What could be bridging the 2 bridges, except the guest VM (which is a stock Ubuntu install)? I am at a complete loss! Thanks.

  • SAPPHIRE HD 7770 no audio on HDMI TV display

    - by zeroconf
    I have SAPPHIRE HD 7770 and cannot get work audio over HDMI. http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1159&lid=1&pid=1452&leg=0 I use Ubuntu 12.04 LTS 64-bit version with all current updates. I tried at /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" ... it didn't help. It's probably I use proprietary driver -this seems to be open source driver. I use the driver, what jockey-gtk (additional drivers) offered me: ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER <---- I installed that one ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER (post-release update) So - I installed the first one, because installing second version failed. Everything went fine but no sound at TV display by HDMI. Even Gnome sound mixer doesn't show HDMI choice. Using 32" Samsung B530 LCD TV - http://www.lcdbesttv.com/2010/02/samsung-b530-series-lcd-tv/ I have Asus P8Z77-M motherboard - http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z77M/ - there is also HDMI integrated. When I put HDMI cord to that plug, then even Gnome sound mixer showed HDMI audio but it didn't work. I have set from BIOS, that I use that SAPPHIRE HD 7770 from PCIe.

  • Oracle Java Embedded Client 1.1 Released

    - by Roger Brinkley
    Yesterday an update release of Oracle Java Embedded Client (OJEC) 1.1 quietly slipped out door for general availability. Until last year it was pretty difficult to get your hands on either a Connected Limited Device Configuration (CLDC) for small devices or a Connected Device Configuration (CDC) for medium devices java implementation without a substantial initial commitment. But with the the release of OJWC (CLDC) and OJEC (CDC) last year that has changed. OJEC 1.1 is a binary distribution designed for installation on medium configurations which is a mid range processor requiring a  slow startup time, seamless upgrades, in a cost sensitive hardware environment  anywhere from 3.5mb to 8 mb. There are headless as well as headed versions available. It is intended for devices, such as Blu-­-ray Disc players, set-­-top boxes, residential gateways,VOIP phones, and similar. From a software point of view, OJEC is the Java runtime platform implementation of Connected Device Configuration (CDC v1.1, JSR-­-218), Foundation Profile (FP v1.1, JSR-­-219), and Personal Basis Profile (PBP v1.1, JSR-­-217)  and includes optional packages RMI (JSR 66), JDBC (JSR 169) and XML API for Java ME (JSR 280), and Java TV (JSR-­-927). New to this release is support for the XML API (JSR 280) and a number of bug fixes and performance enhancements, including an improved Just-in-Time (JIT) compilation for the x86 chipset architecture. The platforms supported include ArmV5, ArmV6/ArmV7, MIPS 32 74K, and X86 in headless mode. For embedded developers there are number of advantages to using Java and if you have shied away from the JavaME edition in the past I would encourage you to look into the updated version of OJEC 1.1.

  • Access a mounted Windows share from the command line

    - by Bryan
    Hello All, I use the "Connect to Server..." option under the "Places" menu to connect to a Windows share in my work environment. When I do so, I can access the Windows share via Nautilus, but I can't figure out how to access the share from the command line without using smbclient. For example, the share isn't mounted under /mnt or /media. Is it possible to access the mounted Windows share from the command line without using smbclient?

    I am working with some USB and Serial micro-controllers. Everytime I plug a device I have to do the following command to give it write access, and also my password: sudo chmod 666 /dev/ttyUSB0 Can I set my Ubuntu to automatically give write access to pluged in devices? If not, how can I make a batch file that I can easily give the access to port I want for example if I run the following command it does the job: giveaccess -usb0

  • Using the Java SE 8 Date Time API with JPA 2.1

    - by reza_rahman
    Most of you are hopefully aware of the new Date Time API included in Java SE 8. If you are not, you should check them out right now using the Java Tutorial Trail dedicated to the topic. It is a significantly leap forward in processing temporal data in Java. For those who already use Joda-Time the changes will look very familiar - very simplistically speaking the Java SE 8 feature is basically Joda-Time standardized. Quite naturally you will likely want to use the new Date Time APIs in your JPA domain model to better represent temporal data. The problem is that JPA 2.1 will not support the new API out of the box. So what are you to do? Fortunately you can make use of fairly simple JPA 2.1 Type Converters to use the Date Time API in your JPA domain classes. Steven Gertiser shows you how to do it in an extremely well written blog entry. Besides explaining the problem and the solution the entry is actually very good for getting a better understanding of JPA 2.1 Type Converters as well. I think such a set of converters may be a good fit for Apache DeltaSpike as a Java EE 7 extension? In case you are wondering about Java SE 8 support in the JPA specification itself, Nick Williams has already entered an excellent, well researched JIRA entry asking for such support in a future version of the JPA specification that's well worth looking at. Another possibility of course is for JPA providers to start supporting the Date Time API natively before anything is formalized in the specification. What do you think?

  • Recent Ubuntu update prevents MySQL root access

    - by Rhys
    I recently updated my Ubuntu (10.04 LTS) server (apt-get update, apt-get upgrade), and everything works fine, apart from the root access to my MySQL database. phpMyAdmin, CakePHP, and essentially all connections return similar access errors. For example, PMA returns 'Connection for controluser as defined in your configuration failed.' I have tried to find similar examples of this instance, but cannot find assistance in what configuration I should be changing to restore root log in access. The same issue has occurred on two servers. One has additional users so I could get around it, but the other is a new development server with only root MySQL access, so I am stuck on how to resolve this.

  • Java SE 8 (with JavaFX) Developer Preview Release for ARM

    - by Roger Brinkley
    In an effort to get ARM developers testing Java SE 8 before the scheduled release later this year a Java SE 8 Developer Preview Release for ARM has been made available. This release has been tested on the Raspberry PI but should work on other ARM platforms. In addition to the new Java SE features, this release provides specific support of hard float GPU on the Raspberry PI. The support for hard float GPU has been anticipated by a number of developers.

  • Why can't I open my Access application in design mode?

    - by mmyers
    I have been given an Access 2007 application (mainly VB code) that I need to modify. It has been locked down for production, so the toolbars and so forth are not visible. However, it is a .mdb file, not .mde, so in theory it should be possible to get into design mode by holding Shift while opening it. But that method has only worked a total of three times out of the (probably) 60 or 70 times I've tried. I realize now that I should have enabled the toolbars while I had it open, but unfortunately hindsight doesn't get me anywhere now. Does anyone know what might be causing the problem? Is it my own fault, or the application's, or Access's?

    - by Morgeh
    Anyone got any ideas how to set up a wireless network bridge between the routers mentioned above? I have a router connected to the internet in one part of the house (BTVoyager) but the wireless range doesnt reach to the other end of the house :-( I also have two spare wireless routers(Belkin G+ Mimo and D-Link DSL-G604T) but as far as I can tell neither of them support wireless bridging.

  • Access Control Lists for Roles

    - by Kyle Hatlestad
    Back in an earlier post, I wrote about how to enable entity security (access control lists, aka ACLs) for UCM 11g PS3.  Well, there was actually an additional security option that was included in that release but not fully supported yet (only for Fusion Applications).  It's the ability to define Roles as ACLs to entities (documents and folders).  But now in PS5, this security option is now fully supported.   The benefit of defining Roles for ACLs is that those user roles come from the enterprise security directory (e.g. OID, Active Directory, etc) and thus the WebCenter Content administrator does not need to define them like they do with ACL Groups (Aliases).  So it's a bit of best of both worlds.  Users are managed through the LDAP repository and are automatically granted/denied access through their group membership which are mapped to Roles in WCC.  A different way to think about it is being able to add multiple Accounts to content items...which I often get asked about.  Because LDAP groups can map to Accounts, there has always been this association between the LDAP groups and access to the entity in WCC.  But that mapping had to define the specific level of access (RWDA) and you could only apply one Account per content item or folder.  With Roles for ACLs, it basically takes away both of those restrictions by allowing users to define more then one Role and define the level of access on-the-fly. To turn on ACLs for Roles, there is a component to enable.  On the Component Manager page, click the 'advanced component manager' link in the description paragraph at the top.   In the list of Disabled Components, enable the RoleEntityACL component. Then restart.  This is assuming the other configuration settings have been made for the other ACLs in the earlier post.   Once enabled, a new metadata field called xClbraRoleList will be created.  If you are using OracleTextSearch as the search indexer, be sure to run a Fast Rebuild on the collection. For Users and Groups, these values are automatically picked up from the corresponding database tables.  In the case of Roles, there is an explicitly defined list of choices that are made available.  These values must match the roles that are coming from the enterprise security repository. To add these values, go to Administration -> Admin Applets -> Configuration Manager.  On the Views tab, edit the values for the ExternalRolesView.  By default, 'guest' and 'authenticated' are added.  Once added, you can assign the roles to your content or folder. If you are a user that can both access the Security Group for that item and you belong to that particular Role, you now have access to that item.  If you don't belong to that Role, you won't! [Extra] Because the selection mechanism for the list is using a type-ahead field, users may not even know the possible choices to start typing to.  To help them, one thing you can add to the form is a placeholder field which offers the entire list of roles as an option list they can scroll through (assuming its a manageable size)  and view to know what to type to.  By being a placeholder field, it won't need to be added to the custom metadata database table or search engine.

  • How can I display images on a MS Access 2007+ form with a hyperlink source?

    - by Yaaqov
    I am looking improve the efficiency of an Access 2010 database by using a web server with images and only storing the hyperlink source (i.e, http://www.images.com/images/image1.jpg) in the table. I know that one can save images as "attachements", using a "blob" object type, but when you're dealing with thousands of images, queries are bogged down, and performance suffers. So in short, is there are relatively simple way of displaying images on MS Access forms with a source that is a hyperlink address (storing files locally and using filepaths is not preferable). Thanks.

  • How can I access a Web server in a VM from an iPad?

    - by Nick Haslam
    I have a virtual machine (running Windows Server 2012, if it's relevant), on VMware Workstation. It is running an Apache Tomcat web server, and I'm wanting to access that webserver from an iPad. Is this feasible, or even possible ? I have tried running Connectify Hotspot on the host machine, but that only gets me as far as being able to access a webpage on the host machine. It doesn't look to pass the connection through to the VM as they are on different subnets. Any thoughts are gratefully received.
