    - by Pomario
    I would like to transfer files between my Ubuntu 12.04 and Nexus 7 (Android 4.2) I have followed another post carefully. BUT upon... mount /mnt/nexus7 I get... Android device detected, assigning default bug flags.Listing File Information on Device with name: (NULL) and even doing an "ls" in "/mnt" generates... ls: cannot access nexus7: Transport endpoint is not connected Ideas why that is happening???

  • Enum types, FlagsAttribute & Zero value – Part 2

    - by nmgomes
    In my previous post I wrote about why you should pay attention when using enum value Zero. After reading that post you are probably thinking like Benjamin Roux: Why don’t you start the enum values at 0x1? Well I could, but doing that I lose the ability to have Sync and Async mutually exclusive by design. Take a look at the following enum types: [Flags] public enum OperationMode1 { Async = 0x1, Sync = 0x2, Parent = 0x4 } [Flags] public enum OperationMode2 { Async = 0x0, Sync = 0x1, Parent = 0x2 } To achieve mutually exclusion between Sync and Async values using OperationMode1 you would have to operate both values: protected void CheckMainOperarionMode(OperationMode1 mode) { switch (mode) { case (OperationMode1.Async | OperationMode1.Sync | OperationMode1.Parent): case (OperationMode1.Async | OperationMode1.Sync): throw new InvalidOperationException("Cannot be Sync and Async simultaneous"); break; case (OperationMode1.Async | OperationMode1.Parent): case (OperationMode1.Async): break; case (OperationMode1.Sync | OperationMode1.Parent): case (OperationMode1.Sync): break; default: throw new InvalidOperationException("No default mode specified"); } } but this is a by design constraint in OperationMode2. Why? Simply because 0x0 is the neutral element for the bitwise OR operation. Knowing this singularity, replacing and simplifying the previous method, you get: protected void CheckMainOperarionMode(OperationMode2 mode) { switch (mode) { case (OperationMode2.Sync | OperationMode2.Parent): case (OperationMode2.Sync): break; case (OperationMode2.Parent): default: break; } This means that: if both Sync and Async values are specified Sync value always win (Zero is the neutral element for bitwise OR operation) if no Sync value specified, the Async method is used. Here is the final method implementation: protected void CheckMainOperarionMode(OperationMode2 mode) { if (mode & OperationMode2.Sync == OperationMode2.Sync) { } else { } } All content above prove that Async value (0x0) is useless from the arithmetic perspective, but, without it we lose readability. The following IF statements are logically equals but the first is definitely more readable: if (OperationMode2.Async | OperationMode2.Parent) { } if (OperationMode2.Parent) { } Here’s another example where you can see the benefits of 0x0 value, the default value can be used explicitly. <my:Control runat="server" Mode="Async,Parent"> <my:Control runat="server" Mode="Parent">

  • Why are my scene's depth values not being written to my DepthStencilView?

    - by dotminic
    I'm rendering to a depth map in order to use it as a shader resource view, but when I sample the depth map in my shader, the red component has a value of 1 while all other channels have a value of 0. The Texture2D I use to create the DepthStencilView is bound with the D3D11_BIND_DEPTH_STENCIL | D3D11_BIND_SHADER_RESOURCE flags, the DepthStencilView has the DXGI_FORMAT_D32_FLOAT format, and the ShaderResourceView's format is D3D11_SRV_DIMENSION_TEXTURE2D. I'm setting the depth map render target, then i'm drawing my scene, and once that is done, I'm the back buffer render target and depth stencil are set on the output merger, and I'm using the depth map shader resource view as a texture in my shader, but the depth value in the red channel is constantly 1. I'm not getting any runtime errors from D3D, and no compile time warning or anything. I'm not sure what I'm missing here at all. I have the impression the depth value is always being set to 1. I have not set any depth/stencil states, and AFAICT depth writing is enabled by default. The geometry is being rendered correctly so I'm pretty sure depth writing is enabled. The device is created with the appropriate debug flags; #if defined(DEBUG) || defined(_DEBUG) deviceFlags |= D3D11_CREATE_DEVICE_DEBUG | D3D11_RLDO_DETAIL; #endif This is how I create my depth map. I've omitted error checking for the sake of brevity D3D11_TEXTURE2D_DESC td; td.Width = width; td.Height = height; td.MipLevels = 1; td.ArraySize = 1; td.Format = DXGI_FORMAT_R32_TYPELESS; td.SampleDesc.Count = 1; td.SampleDesc.Quality = 0; td.Usage = D3D11_USAGE_DEFAULT; td.BindFlags = D3D11_BIND_DEPTH_STENCIL | D3D11_BIND_SHADER_RESOURCE; td.CPUAccessFlags = 0; td.MiscFlags = 0; _device->CreateTexture2D(&texDesc, 0, &this->_depthMap); D3D11_DEPTH_STENCIL_VIEW_DESC dsvd; ZeroMemory(&dsvd, sizeof(dsvd)); dsvd.Format = DXGI_FORMAT_D32_FLOAT; dsvd.ViewDimension = D3D11_DSV_DIMENSION_TEXTURE2D; dsvd.Texture2D.MipSlice = 0; _device->CreateDepthStencilView(this->_depthMap, &dsvd, &this->_dmapDSV); D3D11_SHADER_RESOURCE_VIEW_DESC srvd; srvd.Format = DXGI_FORMAT_R32_FLOAT; srvd.ViewDimension = D3D11_SRV_DIMENSION_TEXTURE2D; srvd.Texture2D.MipLevels = texDesc.MipLevels; srvd.Texture2D.MostDetailedMip = 0; _device->CreateShaderResourceView(this->_depthMap, &srvd, &this->_dmapSRV);

  • OpenSSL in C++ email client - server closes connection with TLSv1 Alert message

    - by mice
    My app connects to a IMAP email server. One client configured his server to reject SSLv2 certificates, and now my app fails to connect to the server. All other email clients connect to this server successfully. My app uses openssl. I debugged by creating minimal openssl client and attempt to connect to the server. Below is the code with connects to the mail server (using Windows sockets, but same problem is with unix sockets). Server sends its initial IMAP greeting message, but after client sends 1st command, server closes connection. In Wireshark, I see that after sending command to server, it returns TLSv1 error message 21 (Encrypted Alert) and connection is gone. I'm looking for proper setup of OpenSSL for this connection to succeed.

  • Can my machine run Ubuntu( kubuntu | xubuntu | mint ) 12.04 WELL?

    - by Steve
    I have a 9 year old computer packing the hardware listed below. My question is, can I run 12.04 ( Ubuntu, Kubuntu, MINT or Xubuntu ) WELL? I was running Ubuntu 10.10 and I upgraded to 12.04 by going through each release via the update manager: 11.04 - 11.10 -12.04 During the installation process for 12.04 I saw an error message that there was an error installing and setting up part of the kernel. Later, when I tried installing a package in synaptic, I got another error message mentioning the kernel. When I rebooted, I got told somehting about my video and graphics was not configured properly and that I would have to do it manually ( like I know ). It gave me the option to enter the system in low graphics mode, but it just hanged. I had an old livecd of Xubuntu 10.10 around so I used that to get into my computer and copy data over to an external hard drive. I think tried to install Xubuntu 10.10 from the livecd, with the option "download updates" checked. The install process moved along a bit, then halted for about 5 hours. I rebooted my machine and tried the Xubuntu 10.10 installer WITHOUT the option to "download updates". The install completed in about 15 minutes. So, all of that is making me wonder if there is someting about 12.04 that does not like my hardware. I'm willing to try again, but only if I know I will not have to spend hours just to get to an error message and a hosed up system like I did last night. I also think I have a lot more RAM than is being reported in the output below. I had extra ram installed last year. I'm not good with the command line readouts, but there seems like there should be a lot more. I wasn't thrilled with Unity. I am willing to try Kubuntu 12.04. Will I run into the same problems? What is the highest version of a *ubuntu can I upgrade to?

  • Saving project (build) settings in Eclipse CDT [migrated]

    - by Mike Valeriano
    Is there an option somewhere in CDT (Juno) where I can set customized "Release" configurations for my projects? All I want to do for now is to be able to create a new C++ project and have by default the -std=c++11 and -std=gnu11options for the compilers and -s for the linker, and maybe a few other optimization flags. It's not a big hassle to do it every time for every new program, but I was just wondering, since I've been creating a lot of small programs to get to know C++ better.

  • SEO FAQ For Small Business 7 of 10 - How Long For SEO Results? (SEO Results Time Frame)

    The hours and effort needed to increase the visibility of your small business website depend greatly on your marketing plan and which keyword you're going after. A year-long optimization campaign is not unheard of for a large site. If your site is less than three or four months old, or the domain is expiring in less than a year, you may have issues with high rank despite your best efforts as these are 'red flags' to the search engines.

  • How can I recover data from a dmg that cannot mount?

    - by Benjamin Lee
    I backed up a hard drive in a dmg, then reformatted the hard drive. (I had deleted the efi partition before which was preventing me from reinstalling the operation system). When I tried use the restore function in disk utility it gave an input/output error. I get this error with anything I do to the image including mounting, converting, attaching, verifying, scanning, and getting info through hdiutil imageinfo. I have run all of these with hdiutil and the -noverify, -nomount, and -ignorebadchecksums flags. When I copy the image onto another disk/partition I get a different error: something like "No filesystem". I cannot repair the image with disk utility or asr, which both throw the I/O error. When I put the -verbose flag on the command I actually get a different error: "hdiutil: attach failed - No child processes". I have output from both the -verbose and -debug flags but it is fairly long so I had to attach a link to avoid the 3000 character limit. No recovery system can get the data because it is both compressed and unmountable. How can I get the data back, and what has gone wrong? -debug -verbose

  • How can I fix my corrupted RAID1 ext4 partition on a Synology DS212 NAS?

    - by Neil
    I have two identical 3 TB disks that were in a RAID1 array, where one disk crashed. I replaced the failed disk, but not after the RAID partitions got messed up. I need to figure out how to restore the RAID array and get at my ext4 partition. Here are the properties of the surviving disk: # fdisk -l /dev/sda fdisk: device has more than 2^32 sectors, can't use all of them Disk /dev/sda: 2199.0 GB, 2199023255040 bytes 255 heads, 63 sectors/track, 267349 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 267350 2147483647+ ee EFI GPT # parted /dev/sda print Model: ATA ST3000DM001-9YN1 (scsi) Disk /dev/sda: 3001GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 131kB 2550MB 2550MB ext4 raid 2 2550MB 4698MB 2147MB linux-swap(v1) raid 5 4840MB 3001GB 2996GB raid I replaced the failed drive, and cloned the surviving drive to it so I have something to work with. I cloned the drives with dd if=/dev/sdb of=/dev/sda conv=noerror bs=64M, and now /dev/sda and /dev/sdb are identical.

The Inbox sits at the following location /home/admin/MyLibrary/MyVideos/Inbox /home/admin/MyLibrary/MyVideos/Movies The system is a Netgear Stora NAS box that I have root access to. The /home/ folder is mounted as an smb share on various computers around the house. The folder /Inbox cannot be opened on any of those machines (they all connect as 'admin'). When I ssh into the box using the 'admin' credentials I am also unable to access the folder. The folder was created via a Web Admin page hosted on the NAS. The user/group for the Inbox folder was previously apache:www (expected as this folder was created by the web application), but I chmod/chowned the folder as the root user in an attempt to grant the admin user (therefore the rest of the connected machines) access to the files. Sorry for not including this earlier, I wasn't sure if it was relevant and didn't want to confuse the situation. -Thanks 3rd Edit Sorry again - It looks like this NAS is running some custom version of Red Hat, not Debian as previously stated - I'm not sure if this makes a difference

  • Problem setting command-line console resolution. vbeinfo in grub2 does not report all resolutions

    I have a Asus EEE PC 1005P which I installed a Command-line system on using the Alternate Installer CD of Ubuntu Lucid Lynx. Altough I think this is a general linux and grub2 question. I do not have (or want) the X Window System installed. I want to change my console screen resolution (not inside X) to 1024x600.

  • missing network usage through iptables

    - by Purres
    I inserted a rule to iptables to track the input usage to a certain ip address. The vps server's IP is 192.168.1.5 and the guest os's IP is 192.168.1.115. I ran 'yum update' inside the guest OS to get some network traffic. Then I ran iptables -vnL from the hypervisor. However it only showed network usage to the host, but not to the guest. Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target source destination 0 0 0.0.0.0/0 0.0.0.0/0 destination IP range 192.168.1.115-192.168.1.115 1853 114K 0.0.0.0/0 0.0.0.0/0 destination IP range 192.168.1.5-192.168.1.5 I ran tcpdump and the log showed that there're data packets to the guest os. 16:17:43.932514 IP mirrordenver.fdcservers.net.http > 192.168.1.115.34471: Flags [.], seq 17694667:17696115, ack 1345, win 113, options [nop,nop,TS val 1060308643 ecr 1958781], length 1448 16:17:43.932559 IP 192.168.1.115.34471 > mirrordenver.fdcservers.net.http: Flags [.], ack 17696115, win 15287, options [nop,nop,TS val 1958869 ecr 1060308643], length 0 Why the guest OS network usage couldn't be tracked? iptables -L will return the INPUT chain as following: Chain INPUT (policy ACCEPT) target prot opt source destination all -- anywhere anywhere destination IP range 192.168.1.115-192.168.1.115 all -- anywhere anywhere destination IP range 192.168.1.5-192.168.1.5 all -- anywhere anywhere

  • VMware virtual machine network devices malfunctioning

    - by sheepz
    I'm running Ubuntu 10.04 LTS and VMvware workstation 7.0.1 build-227600. The virtual machine i'm running in VMware is a custom distribution built on Debian Linux version 3.1. I'm still pretty much a beginner with UNIX administration. After having messed around with the vmware (changed only the name of the folder, the vmx and and other .v* files accordingly in which the .vmx was situated, and the configuration in the vmx file accordingly), the network devices on the virtual machine do not work anymore. The virtual machine is used for securely sending messages. The virtual machine: As far as I know, this perl file called proxy-gen-ifalias eth0 is responsible for properly setting up the two virtual network devices eth0 and eth1. The Virtual machine comes with a GUI interface in which I have set up two ethernet network devices, one internal, the other external. Now, after having messed around with this, the UI gives me this error message: perl proxy-gen-ifalias eth0 /etc/modprobe.d/alias-eth0 /sbin/update-modules perl proxy-gen-ifalias eth1 /etc/modprobe.d/alias-eth1 /sbin/update-modules ifdown eth0 ifdown: interface eth0 not configured ifdown eth1 ifdown: interface eth1 not configured perl proxy-gen-netcfg /etc/network/interfaces ifup eth0 SICCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device eth0: ERROR while getting interface flags: No such device Failed to bring up eth0. ifconfig eth0 eth0: error fetching interface information: Device not found make: *** [/etc/network/interfaces] Error 1 ~ Here are the contents of the two perl files referred to in the message: paste.pocoo.org/show/2AMzAYhoCRZqlGY7wUFk/ proxy-gen-netcfg

    My machine is running off of a AMD Sempron(tm) X2 190 Processor. According the marketing copy, it should be running at around 2.5 Ghz. Why is the cpu speed being reported as something lower?

  • Mac OS X Client With Static DHCP Assignment Requests Wrong IP via Option 50

    - by Starchy
    I have a number of Mac (and a few Linux) laptops getting DHCP from a Force10 layer 3 switch, the only DHCP server on the subnet. There's a global dynamic pool, and for each full-time employee's laptop I have a single IP static pool set by MAC address. One and only one of the clients, running OS X 10.7.5, consistently fails to get a static assignment. The MAC address in the static pool definition has been carefully re-checked. Running tcpdump on a mirrored port when the laptop connects, I see that it is specifically requesting 10.100.0.252 (a dynamic address): 11:32:10.108280 IP (tos 0x0, ttl 255, id 28293, offset 0, flags [none], proto UDP (17), length 328) 0.0.0.0.bootpc > broadcasthost.bootps: [udp sum ok] BOOTP/DHCP, Request from 3c:07:54:xx:xx:xx (oui Unknown), length 300, xid 0x1399da89, Flags [none] (0x0000) Client-Ethernet-Address 3c:07:54:xx:xx:xx (oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Request Parameter-Request Option 55, length 9: Subnet-Mask, Default-Gateway, Domain-Name-Server, Domain-Name Option 119, LDAP, Option 252, Netbios-Name-Server Netbios-Node MSZ Option 57, length 2: 1500 Client-ID Option 61, length 7: ether 3c:07:54:xx:xx:xx Requested-IP Option 50, length 4: 10.100.0.252 Lease-Time Option 51, length 4: 7776000 Hostname Option 12, length 10: "host-name" END Option 255, length 0 PAD Option 0, length 0, occurs 8 I haven't been able to find any extra system prefs or unusual software on the laptop. Disabling the interface and rebooting or temporarily setting the IP manually both fail to make any difference. Any suggestions appreciated.

  • NFSv3 + ACL: mask is gone on clients

    - by Jorge Suárez de Lis
    I'm sharing a NFS folder among a user group. The default umask on the clients is 0700, and this is a problem because newly created files won't be readable/writable by another users. So, I'm using ACLs to force the umask 0770 on the shared folder, and this works OK on the server, but not on the clients. server # getfacl /export/proyectos getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:mask::rwx default:other::r-x server # getfacl /export/proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx mask::rwx other::--- default:user::rwx default:group::rwx default:mask::rwx default:other::--- As you see, the default (and also a specific on the second directory) mask ACLs are being applied. I mount the whole share on the client: 172.16.54.56:/export/proyectos on /proyectos type nfs (rw,noatime,rsize=131072,wsize=131072,acregmin=10,acl,nfsvers=3,addr=172.16.54.56) But the mask and default:mask ACLs are gone. client $ getfacl /proyectos/ getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/ # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:other::r-x client $ getfacl /proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx other::--- default:user::rwx default:group::rwx default:other::--- It lacks the default:mask and mask ACLs, the only ones that I've setted. So the proposed solution to enforce umask won't work for me. Why is happening this?

  • Centos 6.2 Fresh 'Basic Server' install networking issues

    - by RWC
    I've had a /29 provisioned on a network port for a server and am trying to at least configure the machine so I can ssh into it. It's Centos 6.2 x64 with the Basic Server install. Currently not able to ping gateway or any address for that matter. For reference: Default Interface: em2 Network ID: 66.*.*.0/29 Gateway: 66.*.*.1 Broadcast: 66.*.*.7 Please see my following configs: /etc/sysconfig/network-scripts/ifcfg-em2 DEVICE=em2 NM_CONTROLLED=yes ONBOOT=yes HWADDR=Not Important TYPE=Ethernet BOOTPROTO=none IPADDR=66.*.*.2 PREFIX=29 DNS1=8.8.8.8 DNS2=8.8.4.4 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System em2" NETMASK=255.255.255.248 USERCTL=no $: route -n Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface 66.*.*.0 0.0.0.0 255.255.255.248 U 0 0 0 em2 169.254.0.0 0.0.0.0 255.255.0.0 U 0 1003 0 em2 0.0.0.0 66.*.*.1 0.0.0.0 UG 0 0 0 em2 $: route Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface 66.*.*.0 * 255.255.255.248 U 0 0 0 em2 link-local * 255.255.0.0 U 0 1003 0 em2 default 66.*.*.1 0.0.0.0 UG 0 0 0 em2 $: cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=excalibur.domain.com GATEWAY=66.*.*.1 Keep in mind that I cannot even currently ping the gateway which is quite confusing for me. My /etc/hosts are configured correctly with the *.2 address. I'm not concerned with getting all of the addresses on the /29 up and running yet, just one so I can at least ssh in. Thanks!

  • server and user directly connected no pinging...

    - by jtzero
    I have a server(fedora 12) with two nics on it, directly connected to say 192.168.1.0 and 192.168.2.0 the route table looks like this Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 192.168.1.1 255.255.255.0 U 0 0 0 eth0 192.168.2.0 * 255.255.255.0 U 0 0 0 eth1 eth0 = 192.168.1.15 eth1 = 192.168.2.1 and a directly connected user (Mythdora) on the 192.168.2.0 network with ip 192.168.2.2 and route table like so Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.0 * 255.255.255.0 U 0 0 0 eth0 the cable is a crossover and it works all three nics work -- connected my laptop to either end and assign it a valid 192.168.2.0 ip the pings will work. In fact if I disconnect the server side and plug the eth cable into the laptop and have thte box ping the laptop continually remove the eth cable and plug it back into the server both sides ping... unfortunately the box realizing it's connected to a different pc wipes its route table after say ten minutes or so. if I do a trace route from a box on the 1.0 network to the servers 192.168.2.1 interface never get a reply from it. as a note at one point I could ping the server from the 192.168.2.2 box but the server couldnt ping the 192.168.2.2 box.
