  • How to launch a Windows service network process to listen to a port on a localhost socket that is vi

    - by rwired
    Here's the code (in a standard TService in Delphi): const ProcessExe = 'MyNetApp.exe'; function RunService: Boolean; var StartInfo : TStartupInfo; ProcInfo : TProcessInformation; CreateOK : Boolean; begin CreateOK := false; FillChar(StartInfo,SizeOf(TStartupInfo),#0); FillChar(ProcInfo,SizeOf(TProcessInformation),#0); StartInfo.cb := SizeOf(TStartupInfo); CreateOK := CreateProcess(nil, PChar(ProcessEXE),nil,nil,False, CREATE_NEW_PROCESS_GROUP+NORMAL_PRIORITY_CLASS, nil, PChar(InstallDir), StartInfo, ProcInfo); CloseHandle(ProcInfo.hProcess); CloseHandle(ProcInfo.hThread); Result := CreateOK; end; procedure TServicel.ServiceExecute(Sender: TService); const IntervalsBetweenRuns = 4; //no of IntTimes between checks IntTime = 250; //ms var Count: SmallInt; begin Count := IntervalsBetweenRuns; //first time run immediately while not Terminated do begin Inc(Count); if Count >= IntervalsBetweenRuns then begin Count := 0; //We check to see if the process is running, //if not we run it. That's all there is to it. //if ProcessEXE crashes, this service host will just rerun it if processExists(ProcessEXE)=0 then RunService; end; Sleep(IntTime); ServiceThread.ProcessRequests(False); end; end; MyNetApp.exe is a SOCKS5 proxy listening on port 9870. Users configure their browser to this proxy which acts as a secure-tunnel/anonymizer. All works perfectly fine on 2000/XP/2003, but on Vista/Win7 with UAC the service runs in Session0 under LocalSystem and port 9870 doesn't show up in netstat for the logged-in user or Administrator. Seems UAC is getting in my way. Is there something I can do with the SECURITY_ATTRIBUTES or CreateProcess, or is there something I can do with CreateProcessAsUser or impersonation to ensure that a network socket on a service is available to logged-in users on the system (note, this app is for mass deployment, I don't have access to user credentials, and require the user elevate their privileges to install a service on Vista/Win7)

    I'm using a WPA2 EAP network. I'm sitting next to the access point. The connection keeps dropping and taking ~10 seconds to reconnect. My other devices are staying online.

  • Oracle Social Network Developer Challenge: Bezzotech

    - by Kellsey Ruppel
    Originally posted by Jake Kuramoto on The Apps Lab blog. I’ve covered all the entries we had for the Oracle Social Network Developer Challenge, the winners, Dimitri and Martin, HarQen, TEAM Informatics and John Sim from Fishbowl Solutions, and today, I’m giving you bonus coverage. Friend of the ‘Lab, Bex Huff (@bex) from Bezzotech (@bezzotech), had an interesting OpenWorld. He rebounded from an allergic reaction to finish his entry, Honey Badger, only to have his other OpenWorld commitments make him unable to present his work. Still, he did a bunch of work, and I want to make sure everyone knows about the Honey Badger. If you’re wondering about the name, it’s a meme; “honey badger don’t care.” Bex tackled a common problem with social tools by adding game mechanics to create an incentive for people to keep their profiles updated. He used a Hot-or-Not style comparison app that poses expertise questions and awards a badge to the winner. Questions are based on whatever attributes the business wants to emphasize. The goal is to find the mavens in an organization, give them praise and recognition, ideally creating incentive for everyone to raise their games. In his own words: There is a real information quality problem in social networks. In last year’s keynote, Larry Elison demonstrated how to use the social network to track down resources that have the skill sets needed for specific projects. But how well would that work in real life? People usually update that information with the basic profile information, but they rarely update their profiles with latest news items, projects, customers, or skills. It’s a pain. Or, put another way, when was the last time you updated your LinkedIn profile? Enter the Honey Badger! This is a example of a comparator app that gamifies the way people keep their profiles updated, which ensures higher quality data in the social network. An administrator comes up with a series of important questions: Who is a better communicator? Who is a better Java programmer? Who is a better team player? And people would have a space in their profile to give a justification as to why they have these skills. The second part of the app is the comparator. It randomly shows two people, their names, and their justification for why they have these skills. You will click on one of them to “vote” for them, then on the next page you will see the results from the previous match, and get 2 new people to vote on. Anybody with a winning score wins a “Honey Badge” to be displayed on their profile page, which proudly states that their peers agree that this person has those skills. Once a badge is won, it will be jealously guarded. The longer your go without updating your profile, the more likely it is that you will lose your badge. This “loss aversion” is well known in psychology, and is a strong incentive for people to keep their profiles up to date. If a user sees their rank drop from 90% to 60%, they will find the time to update their justification! Unfortunately, during the hackathon we were not allowed to modify the schema to allow for additional fields such as “justification.” So this hack is limited to just the one basic question: who is the bigger Honey Badger? Here are some shots of the Honey Badger application: #gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } Thanks to Bex and everyone for participating in our challenge. Despite very little time to promote this event, we had a great turnout and creative and useful entries. The amount of work required to put together these final entries was significant, especially during a conference, and the judges and all of us involved were impressed at how much work everyone was able to do. Congrats to everyone, pat yourselves on the back. Stay tuned if you’re interested in challenges like these. We’ll likely be running similar events in the not-so-distant future.

  • Can't connect to DeploymentShare$ from PC attempting to MDT, but can other PCs on the network

    - by Moman10
    I am in the process of setting up MDT and have run across a problem. MDT is installed on a Windows 2012 server, MDT version 6.2.5019.0. Using WDS as well. Active Directory domain, the server is up to date and on the network. I boot up the PC, it gets an address from DHCP, pulls down the LiteTouchPE_x64.wim image and goes into the MS Solution Accelerators screen, the Processing Bootstrap Settings box comes up and processes for a couple of seconds, then goes away, it sits there for another minute or so and then gives the error: A connection to the deployment share (\\Acme-MDT\DeploymentShare$) could not be made. Can not reach the DeployRoot. Possible Cause: Network Routing error or Network Configuration Error." I can then retry or cancel. I have seen this error online but so far nothing that helps fix it, but seems to be an issue with the FQDN. I verified that I am getting an IP address and that I can successfully ping the MDT server if I use the FQDN, but can not just by it's A record of Acme-MDT. I tried manually mapping the network share using net use and it works if I use the FQDN, but it fails with an error code 53, "Network path not found" if I just use the A record of Acme-MDT. Here is the net use command I'm using: net use * \\Acme-MDT\DeploymentShare$ /u:Domain\Administrator It gives the error System Error 53, Network path not found (and doesn't prompt for a password), but if I use the FQDN of \\Acme-MDT.domain.com\DeploymentShare$ it works fine to map the drive. I guess the problem is, when it tries to load the image, it is trying to start from \\Acme-MDT\DeploymentShare$ and I need it to start from \\Acme-MDT.domain.com\DeploymentShare$, but not sure how to get it to do that. I've put the fully qualified path in CustomSettings.ini and bootstrap, updated the deployment share, regenerated the boot image and replaced the boot wim in WDS. Or, if someone has an idea as to why it's acting this way and knows a way around it. The end result is what matters! :) I did verify in DNS that Acme-MDT is there, with the proper IP, and I can successfully use the net use command to map this drive from a couple other computers that are already on the network. I am assuming it has something to do with that computer not already being part of the domain, but I'm honestly at a loss as to how to fix it. Any ideas are appreciated, thanks in advance for your help!

  • tc rules block traffic from some hosts at network

  • Network switching issues with MacOS 10.7?

    - by Denis
    I'm having a wired problem and hope somebody can tip me, what way should I dig to. I'm using MacBookPro with Lion 10.7.3 both at my working place & at home. At working place, we have a domain-based network with 802.1x authorization (more than 400 computers) and to connect it I'm using Ethernet cable. IP range is 10.10.2.*. All network settings are setup automatically by DHCP. Also, in settings, I have Network Account Server setup in the User&Groups Settings for my work Domain server - and it is available only from corporate network. At home, I have an ADSL router, that shares Internet connection by WiFi in NAT mode. I'm using WiFi to connect it. Router gives out addresses from 192.168.1.* range and all settings are also set up by router's DHCP. So, my problem is the following. When I come back home from the office, I open my MacBook and AirPort automatically connects my WiFi network. After this, for about 1 minute I'm able to browse sites & ping hosts successfully. But after this minute, network connection is broken down. All pings return time-out. trace route to google.com stops on 192.168.1.1 (which is my router). This lasts for 3-4 minutes. After that network connection is automatically repaired and all pings go smoothly again. At the same time, when my MacBook return timeouts, I can successfully ping any host from my wife's MacBook - so this doesn't look like router issue. When I come to the office, I don't have any issues and Internet connection is available & stable moments after ethernet cable plugged in. Do anybody has any clues about this? What should I monitor & what settings look for resolving this issue? Please, ask, what additional information should I provide. Hoping for good advice & thanks in advance!

  • Week 21: FY10 in the Rear View Mirror

    - by sandra.haan
    FY10 is coming to a close and before we dive into FY11 we thought we would take a walk down memory lane and reminisce on some of our favorite Oracle PartnerNetwork activities. June 2009 brought One Red Network to partners offering access to the same virtual kickoff environment used by Oracle employees. It was a new way to deliver valuable content to key stakeholders (and without the 100+ degree temperatures). Speaking of hot, Oracle also announced in June new licensing options for our ISV partners. This model enables an even broader community of ISVs to build, deploy and manage SaaS applications on the same platform. While some people took the summer off, the OPN Program team was working away to deliver a brand new partner program - Oracle PartnerNetwork Specialized - at Oracle OpenWorld in October. Specialized. Recognized. Preferred. If you haven't gotten the message yet, we may need an emergency crew to pull you out from that rock you've been hiding under. But seriously, the announcement at the OPN Forum drew a big crowd and our FY11 event is shaping up to be just as exciting. OPN Specialized was announced in October and opened our doors for enrollment in December 2009. To mark our grand opening we held our first ever social webcast allowing partners from around the world to interact with us live throughout the day. We had a lot of great conversations and really enjoyed the chance to speak with so many of you. After a short holiday break we were back at it - just a small announcement - Oracle's acquisition of Sun. In case you missed it, here is a short field report from Ted Bereswill, SVP North America Alliances & Channels on the partner events to support the announcement: And while we're announcing things - did we mention that both Ted Bereswill and Judson Althoff were named Channel Chiefs by CRN? Not only do we have a couple of Channel Chiefs, but Oracle also won the Partner Program 5 Star Programs Award and took top honors at the CRN Channel Champion Awards for Financial Factors/Financial Performance in the category of Data and Information Management and the and Xchange Solution Provider event in March 2010. We actually caught up with Judson at this event for a quick recap of our participation: But awards aside, let's not forget our main focus in FY10 and that is Specialization. In April we announced that we had over 35 Specializations available for partners and a plan to deliver even more in FY11. We are just days away from the end of FY10 but hope you enjoyed our walk down memory lane. We are already planning lots of activity for our partners in FY11 starting with our Partner Kickoff event on June 29th. Join us to hear the vision and strategy for FY11 and interact with regional A&C leaders. We look forward to talking with you then. The OPN Communications Team

  • recommendations for disk -> usb backup software

    - by TWood
    Recently I lost a tape drive and rather than repair the unit I decided that backups to usb external drives would be cheaper. In the past I used NTBackup and figured that the new server 2008 R2 backup wbadmin utility would be able to meet my needs. It does not. I am looking for recommendations for another utility that i can use. My requirements are: -backup local disk in addition to files on a network share -scheduled task integration (or some gui options to manage schedule) -non-incremental backup Basically I could do this all with WBAdmin if it just supported network shares. I saw some links that described attaching a vhd pointed to a network share but I am trying to avoid hacks like that. If i'm going to do all that trouble I'd just as well manually copy the directories over myself. If anyone has any software suggestions that might make this task easier for me let me know please. I am considering BackupAssist but can only find a few reviews here and there for it.

  • OSX: How to get a volume name (or bsd name) from a IOUSBDeviceInterface or location id

    - by LG
    Hi, I'm trying to write an app that associates a particular USB string descriptor (of a USB mass storage device) with its volume or bsd name. So the code goes through all the connected USB devices, gets the string descriptors and extracts information from one of them. I would like to get the volume name of those USB devices. I can't find the right API to do that. I have tried to do that: DASessionRef session = DASessionCreate(kCFAllocatorDefault); DADiskRef disk_ref = DADiskCreateFromIOMedia(kCFAllocatorDefault, session, usb_device_ref); const char* name = DADiskGetBSDName(disk_ref); But the DADiskCreateFromIOMedia function returned nil, I assume the usb_device_ref that I passed was not compatible with the io_service_t that the function is expecting. So how can I get the volume name of a USB device? Could I use the location id to do that? Thanks for reading. -L FOO_Result result = FOO_SUCCESS; mach_port_t master_port; kern_return_t k_result; io_iterator_t iterator = 0; io_service_t usb_device_ref; CFMutableDictionaryRef matching_dictionary = NULL; // first create a master_port if (FOO_FAILED(k_result = IOMasterPort(MACH_PORT_NULL, &master_port))) { fprintf(stderr, "could not create master port, err = %d\n", k_result); goto cleanup; } if ((matching_dictionary = IOServiceMatching(kIOUSBDeviceClassName)) == NULL) { fprintf(stderr, "could not create matching dictionary, err = %d\n", k_result); goto cleanup; } if (FOO_FAILED(k_result = IOServiceGetMatchingServices(master_port, matching_dictionary, &iterator))) { fprintf(stderr, "could not find any matching services, err = %d\n", k_result); goto cleanup; } while (usb_device_ref = IOIteratorNext(iterator)) { IOReturn err; IOCFPlugInInterface **iodev; // requires <IOKit/IOCFPlugIn.h> IOUSBDeviceInterface **dev; SInt32 score; err = IOCreatePlugInInterfaceForService(usb_device_ref, kIOUSBDeviceUserClientTypeID, kIOCFPlugInInterfaceID, &iodev, &score); if (err || !iodev) { printf("dealWithDevice: unable to create plugin. ret = %08x, iodev = %p\n", err, iodev); return; } err = (*iodev)->QueryInterface(iodev, CFUUIDGetUUIDBytes(kIOUSBDeviceInterfaceID), (LPVOID*)&dev); (*iodev)->Release(iodev); // done with this FOO_String string_value; UInt8 string_index = 0x1; FOO_Result result = FOO_SUCCESS; CFStringRef device_name_as_cf_string; do { if (FOO_SUCCEEDED(result = FOO_GetStringDescriptor(dev, string_index, 0, string_value))) { printf("String at index %i is %s\n", string_index, string_value.GetChars()); // extract the command code if it is the FOO string if (string_value.CompareN("FOO:", 4) == 0) { FOO_Byte code = 0; FOO_HexToByte(string_value.GetChars() + 4, code); // Get other relevant information from the device io_name_t device_name; UInt32 location_id = 0; // Get the USB device's name. err = IORegistryEntryGetName(usb_device_ref, device_name); device_name_as_cf_string = CFStringCreateWithCString(kCFAllocatorDefault, device_name, kCFStringEncodingASCII); err = (*dev)->GetLocationID(dev, &location_id); // TODO: get volume or BSD name // add the device to the list break; } } string_index++; } while (FOO_SUCCEEDED(result)); err = (*dev)->USBDeviceClose(dev); if (err) { printf("dealWithDevice: error closing device - %08x\n", err); (*dev)->Release(dev); return; } err = (*dev)->Release(dev); if (err) { printf("dealWithDevice: error releasing device - %08x\n", err); return; } IOObjectRelease(usb_device_ref); // no longer need this reference }

  • Ubuntu 12 crashed and took down network

    - by Leopd
    We recently set up a new Ubuntu 12.04LTS server on our network. It's not fully configured so it's not doing much beyond sshd and a default apache2 install. But this evening it appears to have crashed. It wasn't responding to the network or the keyboard. But the worst part is, it took down the entire network. My knowledge of the network stack below OSI layer 3 is very limited, so the rest confuses me. When this machine was physically connected to the network, no other machine could connect to the outside internet. When things were broken, running arp showed that our gateway's IP address (10.0.1.1) was listed as "invalid." Unplugging the server from the network fixed the problem, and plugging it back in broke it again. So the crashed server was advertising itself as owning the gateway's IP address? There's nothing at all in syslog during the time when it was causing problems. Any ideas about how to figure out what went wrong or what we can do to prevent it from happening again? I'm hesitant to even put the machine back on the network right now. Update ** It crashed again, and I ran tcpdump -penn arp (thanks bahamat!) for several minutes and got this...

  • Multiple network installs with cached downloads

    - by popey
    I tend to do lots of Ubuntu installs, and I'd like them to be up to date from the moment I do them, and not have to install a bazillion updates as soon as the install finishes. I'd also like to cache those packages somewhere on a machine on my LAN, so I don't re-download all the packages every time. How easy is this to achieve? Is there a guide somewhere to making this happen? Bonus points if I don't have to burn any CDs or use USB sticks! Edit: I have noticed a lot of guides for PXE booting and would be tempted to set this up but every time I find one they seem to be old/outdated and broken. My home server runs 10.04 LTS.

  • Proper network configuration for a KVM guest to be on the same networks at the host

    - by Steve Madsen
    I am running a Debian Linux server on Lenny. Within it, I am running another Lenny instance using KVM. Both servers are externally available, with public IPs, as well as a second interface with private IPs for the LAN. Everything works fine, except the VM sees all network traffic as originating from the host server. I suspect this might have something to do with the iptables-based firewall I'm running on the host. What I'd like to figure out is: how to I properly configure the host's networking such that all of these requirements are met? Both host and VMs have 2 network interfaces (public and private). Both host and VMs can be independently firewalled. Ideally, VM traffic does not have to traverse the host firewall. VMs see real remote IP addresses, not the host's. Currently, the host's network interfaces are configured as bridges. eth0 and eth1 do not have IP addresses assigned to them, but br0 and br1 do. /etc/network/interfaces on the host: # The primary network interface auto br1 iface br1 inet static address 24.123.138.34 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 gateway 24.123.138.33 bridge_ports eth1 bridge_stp off auto br1:0 iface br1:0 inet static address 24.123.138.36 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 # Internal network auto br0 iface br0 inet static address 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 bridge_ports eth0 bridge_stp off This is the libvirt/qemu configuration file for the VM: <domain type='kvm'> <name>apps</name> <uuid>636b6620-0949-bc88-3197-37153b88772e</uuid> <memory>393216</memory> <currentMemory>393216</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='cdrom'> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='file' device='disk'> <source file='/raid/kvm-images/apps.qcow2'/> <target dev='vda' bus='virtio'/> </disk> <interface type='bridge'> <mac address='54:52:00:27:5e:02'/> <source bridge='br0'/> <model type='virtio'/> </interface> <interface type='bridge'> <mac address='54:52:00:40:cc:7f'/> <source bridge='br1'/> <model type='virtio'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain> Along with the rest of my firewall rules, the firewalling script includes this command to pass packets destined for a KVM guest: # Allow bridged packets to pass (for KVM guests). iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT (Not applicable to this question, but a side-effect of my bridging configuration appears to be that I can't ever shut down cleanly. The kernel eventually tells me "unregister_netdevice: waiting for br1 to become free" and I have to hard reset the system. Maybe a sign I've done something dumb?)

  • Two network interfaces and two IP addresses on the same subnet in Linux

    - by Scott Duckworth
    I recently ran into a situation where I needed two IP addresses on the same subnet assigned to one Linux host so that we could run two SSL/TLS sites. My first approach was to use IP aliasing, e.g. using eth0:0, eth0:1, etc, but our network admins have some fairly strict settings in place for security that squashed this idea: They use DHCP snooping and normally don't allow static IP addresses. Static addressing is accomplished by using static DHCP entries, so the same MAC address always gets the same IP assignment. This feature can be disabled per switchport if you ask and you have a reason for it (thankfully I have a good relationship with the network guys and this isn't hard to do). With the DHCP snooping disabled on the switchport, they had to put in a rule on the switch that said MAC address X is allowed to have IP address Y. Unfortunately this had the side effect of also saying that MAC address X is ONLY allowed to have IP address Y. IP aliasing required that MAC address X was assigned two IP addresses, so this didn't work. There may have been a way around these issues on the switch configuration, but in an attempt to preserve good relations with the network admins I tried to find another way. Having two network interfaces seemed like the next logical step. Thankfully this Linux system is a virtual machine, so I was able to easily add a second network interface (without rebooting, I might add - pretty cool). A few keystrokes later I had two network interfaces up and running and both pulled IP addresses from DHCP. But then the problem came in: the network admins could see (on the switch) the ARP entry for both interfaces, but only the first network interface that I brought up would respond to pings or any sort of TCP or UDP traffic. After lots of digging and poking, here's what I came up with. It seems to work, but it also seems to be a lot of work for something that seems like it should be simple. Any alternate ideas out there? Step 1: Enable ARP filtering on all interfaces: # sysctl -w net.ipv4.conf.all.arp_filter=1 # echo "net.ipv4.conf.all.arp_filter = 1" >> /etc/sysctl.conf From the file networking/ip-sysctl.txt in the Linux kernel docs: arp_filter - BOOLEAN 1 - Allows you to have multiple network interfaces on the same subnet, and have the ARPs for each interface be answered based on whether or not the kernel would route a packet from the ARP'd IP out that interface (therefore you must use source based routing for this to work). In other words it allows control of which cards (usually 1) will respond to an arp request. 0 - (default) The kernel can respond to arp requests with addresses from other interfaces. This may seem wrong but it usually makes sense, because it increases the chance of successful communication. IP addresses are owned by the complete host on Linux, not by particular interfaces. Only for more complex setups like load- balancing, does this behaviour cause problems. arp_filter for the interface will be enabled if at least one of conf/{all,interface}/arp_filter is set to TRUE, it will be disabled otherwise Step 2: Implement source-based routing I basically just followed directions from http://lartc.org/howto/lartc.rpdb.multiple-links.html, although that page was written with a different goal in mind (dealing with two ISPs). Assume that the subnet is 10.0.0.0/24, the gateway is 10.0.0.1, the IP address for eth0 is 10.0.0.100, and the IP address for eth1 is 10.0.0.101. Define two new routing tables named eth0 and eth1 in /etc/iproute2/rt_tables: ... top of file omitted ... 1 eth0 2 eth1 Define the routes for these two tables: # ip route add default via 10.0.0.1 table eth0 # ip route add default via 10.0.0.1 table eth1 # ip route add 10.0.0.0/24 dev eth0 src 10.0.0.100 table eth0 # ip route add 10.0.0.0/24 dev eth1 src 10.0.0.101 table eth1 Define the rules for when to use the new routing tables: # ip rule add from 10.0.0.100 table eth0 # ip rule add from 10.0.0.101 table eth1 The main routing table was already taken care of by DHCP (and it's not even clear that its strictly necessary in this case), but it basically equates to this: # ip route add default via 10.0.0.1 dev eth0 # ip route add 130.127.48.0/23 dev eth0 src 10.0.0.100 # ip route add 130.127.48.0/23 dev eth1 src 10.0.0.101 And voila! Everything seems to work just fine. Sending pings to both IP addresses works fine. Sending pings from this system to other systems and forcing the ping to use a specific interface works fine (ping -I eth0 10.0.0.1, ping -I eth1 10.0.0.1). And most importantly, all TCP and UDP traffic to/from either IP address works as expected. So again, my question is: is there a better way to do this? This seems like a lot of work for a seemingly simple problem.

  • NetworkManager Applet shows no networks

    - by Kkelk
    I am "the friend" referred to in the questions here and here. I decided to come and ask a question myself, as I can still not connect to the wireless network. I downloaded Keryx, as suggested here, and managed to download the necessary package and its dependencies. When I attempted to install the packages on Ubuntu using Keryx, Keryx just closed. Following this, I installed the packages manually using dpkg, and as far as I can tell, this was successful: kieran@ubuntu:~$ cd /host/wifi/Keryx/keryx/projects/Kieran/packages kieran@ubuntu:/host/wifi/Keryx/keryx/projects/Kieran/packages$ sudo dpkg -i *.deb [sudo] password for kieran: Selecting previously deselected package bcmwl-kernel-source.

  • Why did my flash drive become "read only" and (how) can I fix it?

    - by Bob
    I have a brand new flash drive (one week old) that has become marked as read only, by Windows, Kubuntu and a bootable partitioner. Why did this happen? Is it fixable? If it is, how can I fix this? The problem Firstly, this drive is new. It's certainly not been used enough to die from normal wear and tear, though I would not discount defective components. The drive itself has somehow become locked in a read only state. Windows' Disk management: Diskpart: Generic Flash Disk USB Device Disk ID: 33FA33FA Type : USB Status : Online Path : 0 Target : 0 LUN ID : 0 Location Path : UNAVAILABLE Current Read-only State : Yes Read-only : No Boot Disk : No Pagefile Disk : No Hibernation File Disk : No Crashdump Disk : No Clustered Disk : No What really confuses me is Current Read-only State : Yes and Read-only : No. Attempted solutions So far, I've tried: Formatting it in Windows (in Disk management, the format options are greyed out when right clicking). DiskPart Clean (CLEAN - Clear the configuration information, or all information, off the disk.): DISKPART> clean DiskPart has encountered an error: The media is write protected. See the System Event Log for more information. There was nothing in the event log. Windows command line format >format G: Insert new disk for drive G: and press ENTER when ready... The type of the file system is FAT32. Verifying 7740M Cannot format. This volume is write protected. Windows chkdsk: see below for details Kubuntu fsck (through VirtualBox USB passthrough): see below for details Acronis True Image to format, to convert to GPT, to destroy and rebuild MBR, basically anything: failed (could not write to MBR) Details (and a nice story) Background This was a brand new, generic, 8GB flash drive I wanted to create a multiboot flash drive with. It came formatted as FAT32, though oddly a little larger than most 8 GIGAbyte flash drives I've come across. Approximately 127MB was listed as "used" by Windows. I never discovered why. The end usable space was about what I normally expect from a 8GB drive (approx 7.4 GIBIbytes). I had thrown quite a few Linux distros on, along with a copy of Hiren's. They would all boot perfectly. They were put on with YUMI. When I tried to put the Knoppix DVD on, YUMI added an odd video option to its boot comman which caused Knoppix to boot with a black screen on X. ttys 1 through 6 still worked as text only interfaces. A few days later, I took some time to take that odd video option off, making the boot command match the one that comes with Knoppix. On the attempt to boot, Knoppix reported some form of LZMA corruption. Leading up to the current issue I was thinking the Knoppix files may have been corrupted somehow, so I tried reloading it. The drive was nearly full (45MB free), so I deleted a generic ISO that also was not booting. That went fine. I then went through YUMI to 'uninstall' Knoppix, i.e. delete files and remove from the menus. The files went first, then the menus were cleared successfully. However, the free space was stuck at about 700MB, same as it was before removing Knoppix. In the old Knoppix folder, there was a 0 byte file named KNOPPIX that could not be deleted. I tried reinserting the drive to delete this file - without safely removing, if that made a difference (hey, first time for everything). Running the standard Windows chkdsk scan without /r or /f reported errors found. Running with /r just got it stuck. I decided to give fsck a shot, so I loaded up my Kubuntu VM and attached the drive to it with VirtualBox's USB 2.0 passthrough. I umounted it (/dev/sda1) and ran a fsck. There are differences between boot sector and its backup. I chose No action. It told me FATs differ and asked me to select either the first or second FAT. Whichever I selected, I got a notice of Free cluster summary wrong. If I chose Correct, it gave a list of incorrect file names. To try to fix something, at least, I ran it with the -p option. Halfway through fixing the files, the VM froze - I ended its process about ten minutes later. Cause? My next attempt was to use YUMI, again, to rebuild the whole drive. I used YUMI's built in reformat (to FAT32) option and installed a Kubuntu ISO (700MB). The format was successful, however, the extract and copy of Kubuntu (which YUMI uses a 7zip binary for) froze at about 60% done. After waiting for about fifteen minutes (longer than the 3.5GB Knoppix ISO took last time), I pulled the drive out. The drive at this point was already formatted, SYSLINUX already installed, just waiting on the unpacking of an ISO and the modifying of the boot menus. Plugging it back in, it came up as normal - however, any write action would fail. Disk management reported it as read only. On reconnect, it would come up as normal but a write operation would cause it to go read only again. After a few attempts, it started coming up as read only on insertion. Attempts to fix This is when I ran through the attempts listed above, to try and reformat it in case of a faulty format. However the inability to do so even on a bootable disk indicated something more serious is wrong. chkdsk now reports nothing is wrong, and fsck still reports MBR inconsistencies, but now always chooses first FAT automatically after telling me FATs differ. It still does the same Free cluster summary wrong afterwards. I cannot run with -p anymore because it is now marked as read only. It also managed to corrupt my VM's disk somehow on the first attempt (yes, I'm sure I chose sda, which is mapped to a 7.4GB drive - I triple checked). Thank god for snapshots? I'm just about out of ideas. To my inexperienced mind it looks like something in the drive's firmware set it to read only "permanently" somehow - is there any way to reset this? I don't particularly care about keeping data, considering I've reformatted it twice. Also, fixes that keep me in Windows are better; it reduces the risk of me accidentally nuking my main hard drive. Update 1: I pulled apart the drive out of curiosity. As you can see, there are no obvious write protect switches. There is an IC on the other side, ALCOR branded labelled AU6989HL, if that matters. If there appears to be no way to fix this, I'll probably pull out the (glued down) card and put it in a card reader to check if it's the card or the controller that died. Update 2: I've pulled the card off, Windows detects the drive as a card reader now. The contacts on the card don't appear to be used, and there are several rows of holes on the card itself. Putting it into the card reader only detects about 30MB total, RAW. It's probably either the reader incorrectly reporting the card as faulty (as if a real SD card's write protect was switched on) or a bad contact somewhere. If nothing else, I have a spare 8GB Micro SD card now... as soon as I figure out how to format it as 8GB.

  • Software Diagnostics Tool recommendations for Debugging a Windows 8 freeze

    - by Stuart
    I've had my HP Pavillion dv6 laptop since last November - and it has had 8GB RAM and a 256GB Crucial M4 SSD installed since the start. I use it for software development and it's had a Windows 8 RTM installation since early September. Yesterday I had to give a presentation at a customer site - so used Powerpoint for the first time since installing Win8... since that point my machine has 'frozen' every 2 hours or so after startup. There doesn't seem to be any easy to see reason behind the freeze - the system just freezes, even if I have left it idle with just a desktop there. My immediate suspicion is that the SSD is the mostly likely cause of the problem. I've looked at some of the questions on here - e.g. How do I troubleshoot hardware issues related to a computer freeze/crash? - but don't really want to start taking my laptop apart. Another suspicion is that this might be related to the WiFi adapter (Broadcom 802.11n) since I have noticed that this doesn't seem to play perfectly with things like Hyper-V in Win8. Can anyone recommend any software diagnostic tools that I can run in order to evaluate the health of the SSD or of other parts of the system? Thanks Stuart P.S. I doubt Powerpoint is the cause of this, but I may use it as an excuse never to use it again... More realistically perhaps something got damaged during travel to the customer site?

  • Laptop battery holds charge, but won't charge any more.

    - by Jeff
    Ok, I'm sure I will need to replace either my battery or my AC adapter, but would rather not buy one if the other is the problem. My problem is. I have a Sager laptop that gets quite a bit of use. The charging has always been a little bit odd. If I was in the process of using it, it would charge just fine and stay On AC power. If I left it alone, however(power settings to ONLY turn off the monitor) in either Ubuntu or Windows 7 it decides that it didn't want to use AC power anymore and would just start draining the battery until it died. Now, suddenly, it won't charge at all. The capacity was great up to this point which happened in an instant. It will recognize the battery but won't see the AC power if plugged in while the battery is in. I can power up the laptop without the battery and it works fine. If I plug in the battery while powered up it will claim it's charging it, but it stays at the same percentage. If I unplug the power, it will switch over to Battery fine, but I have to power down and unplug the battery to get it back on AC power. I've had dying/dead batteries before but they typically won't hold a full charge anymore but it still winds up to 100% then drops quickly when unplugged. This seems more like a chip problem in the battery to me, but I'm not sure. Any ideas?
