• When pointing to new DNS servers is there any chance of E-mails being lost if the old E-mail hosting service is still up?

  - by LaserBeak

  I am changing webhosts and will be using the new hosts mail servers instead of the old ones. I have created all the correctly named mailboxes on the new service but have also not yet cut ties with the old webhost. I am expecting that even if the new DNS values which point to the new hosts DNS servers and respective SOA\zone file with the new MX values have not yet propagated and an E-mail is directed at the old hosts mail servers as per the mx records in the SOA\zone records which the old hosting provider holds, the E-mail would still come through to the mailbox that's on the old host providers mail servers. So I am just trying to reaffirm if I got this right and it's essentially impossible for me to loose an E-mail since it will hit either the old hosts mail servers or the new ones ? Also is it possible to configure the same E-mail account to check and collect mail from different mail servers by entering multiple pop3 addresses ? And if I choose to keep the old web hosts mail hosting services as a backup by specifying the mx records for it with a lower priority in the SOA records hosted by the new webhost, is it possible to have any incoming E-mails sent to both servers by the mail daemon so I have two copies? Or is my only option having the primary mail server forward the E-mail somehow to the old mailserver ?

• Noting happens when I connect my Iphone 3G to my laptop

  - by Allwar

  Hi, how do i connect my iphone to my laptop (ubuntu 10.04) so that i can sync music and be able to look at it as a usb stick? (this is what I want to do but there is a problem.) When i connect it to my laptop nothing happens, it doesn't show up as an ikon or as a mass storage device. My Iphone runs 4.2.1 it's an Iphone 3G and it's not jailbroken for the moment, is that a problem? My laptop is an Asus 1201n ubuntu 10.04 (64-bits) Bus 002 Device 005: ID 05ac:1292 Apple, Inc. iPhone 3G I connected my Ipod Video (30 gb) and that one doesn't appear as well So I'm kind of stuck now. The problem probably lies in the system, because the usb port is working. Bus 002 Device 006: ID 05ac:1209 Apple, Inc. iPod Video

• Ports do not open after rules appended in iptables

  - by user2699451

  I have a server that I am trying to setup for OpenVPN. I have followed all the steps, but I see that when I try to connect to it in Windows, it doesn't allow me, it just hangs on connecting, so I did a nmap scan and I see that port 1194 is not open so naturally I append the rule to open 1194 with: iptables -A INPUT -i eth0 -p tcp --dport 1194 -j ACCEPT followed by service iptables save and service iptables restart which all executed successfully. Then I try again, but it doesn't work and another nmap scan says that port 1194 is closed. Here is the iptables configuration: # Generated by iptables-save v1.4.7 on Thu Oct 31 09:47:38 2013 *nat :PREROUTING ACCEPT [27410:3091993] :POSTROUTING ACCEPT [0:0] :OUTPUT ACCEPT [5042:376160] -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE -A POSTROUTING -o eth0 -j MASQUERADE -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE -A POSTROUTING -j SNAT --to-source 41.185.26.238 -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE COMMIT # Completed on Thu Oct 31 09:47:38 2013 # Generated by iptables-save v1.4.7 on Thu Oct 31 09:47:38 2013 *filter :INPUT ACCEPT [23571:2869068] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [27558:3656524] :vl - [0:0] -A INPUT -p tcp -m tcp --dport 5252 -m comment --comment "SSH Secure" -j ACCEPT -A INPUT -p icmp -m icmp --icmp-type 8 -m state --state NEW,RELATED,ESTABLISHED -$ -A INPUT -i lo -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -m comment --comment "SSH" -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -m comment --comment "HTTP" -j ACCEPT -A INPUT -p tcp -m tcp --dport 8080 -m comment --comment "HTTPS" -j ACCEPT -A INPUT -p tcp -m tcp --dport 443 -m comment --comment "HTTP Encrypted" -j ACCEP$ -A INPUT -i eth0 -p tcp -m tcp --dport 1723 -j ACCEPT -A INPUT -i eth0 -p gre -j ACCEPT -A INPUT -p udp -m udp --dport 1194 -j ACCEPT -A FORWARD -i ppp+ -o eth0 -j ACCEPT -A FORWARD -i eth0 -o ppp+ -j ACCEPT -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -s 10.8.0.0/24 -j ACCEPT -A FORWARD -j REJECT --reject-with icmp-port-unreachable -A OUTPUT -p icmp -m icmp --icmp-type 0 -m state --state RELATED,ESTABLISHED -j A$ COMMIT # Completed on Thu Oct 31 09:47:38 2013 and my nmap scan from: localhost: nmap localhost Starting Nmap 5.51 ( http://nmap.org ) at 2013-10-31 09:53 SAST Nmap scan report for localhost (127.0.0.1) Host is up (0.000011s latency).

• Send raw data to USB parallel port after upgrading to 11.10

  - by zaphod

  I have a laser cutter connected via a generic USB to parallel adapter. The laser cutter speaks HPGL, as it happens, but since this is a laser cutter and not a plotter, I usually want to generate the HPGL myself, since I care about the ordering, speed, and direction of cuts and so on. In previous versions of Ubuntu, I was able to print to the cutter by copying an HPGL file directly to the corresponding USB "lp" device. For example: cp foo.plt /dev/usblp1 Well, I just upgraded to Ubuntu 11.10 oneiric, and I can't find any "lp" devices in /dev anymore. D'oh! What's the preferred way to send raw data to a parallel port in Ubuntu? I've tried System Settings Printing + Add, hoping that I might be able to associate my device with some kind of "raw printer" driver and print to it with a command like lp -d LaserCutter foo.plt But my USB to parallel adapter doesn't seem to show up in the list. What I do see are my HP Color LaserJet, two USB-to-serial adapters, "Enter URI", and "Network Printer". Meanwhile, over in /dev, I do see /dev/ttyUSB0 and /dev/ttyUSB1 devices for the 2 USB-to-serial adapters. I don't see anything obvious corresponding to the HP printer (which was /dev/usblp0 prior to the upgrade), except for generic USB stuff. For example, sudo find /dev | grep lp produces no output. I do seem to be able to print to the HP printer just fine, though. The printer setup GUI gives it a device URI starting with "hp:" which isn't much help for the parallel adapter. The CUPS administrator's guide makes it sound like I might need to feed it a device URI of the form parallel:/dev/SOMETHING, but of course if I had a /dev/SOMETHING I'd probably just go on writing to it directly. Here's what dmesg says after I disconnect and reconnect the device from the USB port: [ 924.722906] usb 1-1.1.4: USB disconnect, device number 7 [ 959.993002] usb 1-1.1.4: new full speed USB device number 8 using ehci_hcd And here's how it shows up in lsusb -v: Bus 001 Device 008: ID 1a86:7584 QinHeng Electronics CH340S Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x1a86 QinHeng Electronics idProduct 0x7584 CH340S bcdDevice 2.52 iManufacturer 0 iProduct 2 USB2.0-Print iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 32 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 96mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 7 Printer bInterfaceSubClass 1 Printer bInterfaceProtocol 2 Bidirectional iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Device Status: 0x0000 (Bus Powered)

• Help me classify this type of software architecture

  - by Alex Burtsev

  I read some books about software architecture as we are using it in our project but I can't classify the architecture properly. It's some kind of Enterprise Architecture, but what exactly... SOA, ESB (Enterprise Service Bus), Message Bus, Event Driven SOA, there are so many terms in Enterprise software.... The system is based on custom XML messages exchanges between services. (it's not SOAP, nor any other XML based standard, just plain XML). These messages represent notifications (state changes) that are applied to the Domain model, (it's not like CRUD when you serialize the whole domain object, and pass it to service for persistence). The system is centralized, and system participants use different programming languages and frameworks (c++, c#, java). Also, messages are not processed at the moment they are received as they are stored first and the treatment begins on demand. It's called SOA+EDA -:)

• Force usb to use same device id, instead of new one

  - by m s kumar

  I am having some trouble in automating the task. I am testing some android based mobiles in linux machine. The automation script uses the device id under "/dev/bus/usb/001/"053" it will be always under bus 001 only.. But the dev is will be random like if i insert one mobile then the dev id will be 053, if remove and insert it again then the dev id will be 054.. The problem is, when some tests runs on the device and if device gets rebooted then new dev id is showing for the rebooted one and my scripts failing due to new dev id.. Is there any way to force usb devices to use same dev id instead of new one. So that there will be no issues to my tests even after device reboots. Thanks in advance.

• Correcting color-shifted mirrored i915 driver in 12.04?

  - by Will Martin

  I was called in to fix a friend's malfunctioning HP Pavilion. She's not sure exactly which model, but the sticker on the bottom says "G60". The problem was a failed upgrade to 12.04. I was able to mostly repair it with sudo apt-get -f install, which ran setup and configuration for several hundred packages. The biggest problem at the moment is Xorg. The login screen (lightdm) loads normally but at a reduced resolution (1024x768 instead of 1366x768). But once you log in, it looks like this: Observe that the colors of the dock on the left and the bar at the top are normal. But the background is filled with bizarro color-skewed ghost images of the desktop. In all cases, the actual contents of any programs you run is a totally illegible mess, except that the bar at the top of any program windows looks and acts normally. And the ghost images are interactive! For example, if you click the icon in the top right corner to get the "shut down" menu, the same menu will appear in the ghost images below. Starting a terminal will start a terminal window in both the real desktop and the ghost images, and moving it around updates both the real and ghost desktops. I suspect Xorg is using some kind of wrong driver and/or parameter for the graphics hardware. Here is the graphics-relevant portion of the lspci -v output: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information: Len=0a <?> Kernel driver in use: agpgart-intel 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at d0000000 (64-bit, non-prefetchable) [size=4M] Memory at c0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5110 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 3 Kernel driver in use: i915 Kernel modules: i915 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) Subsystem: Hewlett-Packard Company Device 360b Flags: bus master, fast devsel, latency 0 Memory at d2500000 (64-bit, non-prefetchable) [size=1M] Capabilities: [d0] Power Management version 3 I'm not sure what to check next. I would ordinarily check xorg.conf to see what it says, but that apparently doesn't exist any more, and my googling has not yielded any useful techniques for getting Xorg to tell me what settings it decided to use. The weird part is that it works fine on the login screen. It's only when you actually log in as a user that the display gets screwed up. Suggestions?

• Atheros Wireless card shows up as two different models?

  - by geermc4

  Hi I've been fighting these wireless drivers for a few days and just recently i noticed that the model the Wireless controller appears in lspci is different sometimes. This is the data i have after installing Ubuntu Server 64 bit ~# lspci -k .... 04:00.0 Network controller: Atheros Communications Inc.

• USB Mouse sleeping after 5 seconds when on battery

  - by yurividal

  My usb mouse sleeps after 5 seconds of inactivity when running on battery power. It wakes uo again when i press any button on the mouse. This is really annoying. I have made lsusb, and I noticed my mouse is Bus 001 Device 012: ID 04d9:2083 Holtek Semiconductor, Inc. I have checked my /sys/bus/usb/devices/usb1/power/autosuspend but it is already set to 0, and the directory usb1 has many subdirectories which also have autosuspend files, and i dont know how to edit them. Also, I would like a permanent solution, which would work for any mouse, on any of my 3 usb ports. Any ideas? Using: Ubuntu 12.04 64bit

• How to disable integrated webcam and still be able to use an external one

  - by alikasundara

  I am looking for a way to disable the webcam that is integrated into my laptop. The webcam is using uvcvideo module but I do not want to blacklist it since it is also being used by an external webcam I have. Is there any way of disabling the device itself without touching the modules list? This is how the webcams are listed by lsusb. The first one is an integrated one (It is identified by some apps as BisonCam NB Pro), the second one is the external Logitech C525: Bus 002 Device 004: ID 5986:0361 Acer, Inc Bus 003 Device 002: ID 046d:0826 Logitech, Inc. I have already checked BIOS - there is no way of disabling the webcam from there. Besides I would love to learn how to disable the device by ID anyway. Thanks!

• Send raw data to USB parallel port after upgrading to 11.10 oneiric

  - by zaphod

  I have a laser cutter connected via a generic USB to parallel adapter. The laser cutter speaks HPGL, as it happens, but since this is a laser cutter and not a plotter, I usually want to generate the HPGL myself, since I care about the ordering, speed, and direction of cuts and so on. In previous versions of Ubuntu, I was able to print to the cutter by copying an HPGL file directly to the corresponding USB "lp" device. For example: cp foo.plt /dev/usblp1 Well, I just upgraded to Ubuntu 11.10 oneiric, and I can't find any "lp" devices in /dev anymore. D'oh! What's the preferred way to send raw data to a parallel port in Ubuntu? I've tried System Settings Printing + Add, hoping that I might be able to associate my device with some kind of "raw printer" driver and print to it with a command like lp -d LaserCutter foo.plt But my USB to parallel adapter doesn't seem to show up in the list. What I do see are my HP Color LaserJet, two USB-to-serial adapters, "Enter URI", and "Network Printer". Meanwhile, over in /dev, I do see /dev/ttyUSB0 and /dev/ttyUSB1 devices for the 2 USB-to-serial adapters. I don't see anything obvious corresponding to the HP printer (which was /dev/usblp0 prior to the upgrade), except for generic USB stuff. For example, sudo find /dev | grep lp produces no output. I do seem to be able to print to the HP printer just fine, though. The printer setup GUI gives it a device URI starting with "hp:" which isn't much help for the parallel adapter. The CUPS administrator's guide makes it sound like I might need to feed it a device URI of the form parallel:/dev/SOMETHING, but of course if I had a /dev/SOMETHING I'd probably just go on writing to it directly. Here's what dmesg says after I disconnect and reconnect the device from the USB port: [ 924.722906] usb 1-1.1.4: USB disconnect, device number 7 [ 959.993002] usb 1-1.1.4: new full speed USB device number 8 using ehci_hcd And here's how it shows up in lsusb -v: Bus 001 Device 008: ID 1a86:7584 QinHeng Electronics CH340S Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x1a86 QinHeng Electronics idProduct 0x7584 CH340S bcdDevice 2.52 iManufacturer 0 iProduct 2 USB2.0-Print iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 32 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 96mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 7 Printer bInterfaceSubClass 1 Printer bInterfaceProtocol 2 Bidirectional iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Device Status: 0x0000 (Bus Powered)

• Can't control connection bit rate using iwconfig with Atheros TL-WN821N (AR7010)

  - by Paul H

  I'm trying to reduce the connection bit rate on my Atheros TP-Link TL-WN821N v3 usb wifi adapter due to frequent instability issues (reported connection speed goes down to 1Mb/s and I have to physically reconnect the adapter to regain a connection). I know this is a common problem with this device, and I have tried everything I can think of to fix it, including using drivers from linux-backports; compiling and installing a custom firmware (following instructions on https://wiki.debian.org/ath9k_htc#fw-free) and (as a last resort) using ndiswrapper. When using ndiswrapper, the wifi adapter is stable and operates in g mode at 54Mb/s (whilst when using the default ath9k_htc module, the adapter connects in n mode and the bit rate fluctuates constantly). Unfortunately, with this setup I have to run my processor using only one core, since using SMP with ndiswrapper causes a kernel oops on my system. So I want to lock my bit rate to 54Mb/s (or less, if need be) for connection stability, using the ath9k_htc module. I've tried 'sudo iwconfig wlan0 rate 54M'; the command runs with no error but when I check the bit rate with 'sudo iwlist wlan0 bitrate' the command returns: wlan0 unknown bit-rate information.

• Event Aggregator.. not getting a response, how to determine completion?

  - by Duncan_m

  I'm rewriting a vehicle tracking application, a google maps based thing.. The users are able to search for a vehicle by typing a few characters of the vehicles "callsign". My application is based around a sort of "event bus" within Backbone.. when a search occurs I send a message on the bus saying something like "does anyone match this?".. If a marker matches the search term it responds with a sort of "yes, I match!".. My challenge arises when no-one matches, I get no response.. it feels a little hacky to "wait a little while" and check if a response has been recieved.. The application is based around Backbone.js and using the Event Aggregator pattern described in the answer to this question on Stack Overflow: http://stackoverflow.com/questions/7708195/access-function-in-one-view-from-another-in-backbone-js Is there a well defined design pattern that might assist me here? Sending a request for a response and not getting any responses?

• Problems with shutting down JBoss in Eclipse if I change JNDI port

  - by Balint Pato

  1st phase I have a problem shutting down my running JBoss instance under Eclipse since I changed the JNDI port of JBoss. Of course I can shut it down from the console view but not with the stop button (it still searches JNDI port at the default 1099 port). I'm looking forward to any solutions. Thank you! Used environment: JBoss 4.0.2 (using default) Eclipse 3.4.0. (using JBoss Tools 2.1.1.GA) Default ports: 1098, 1099 Changed ports: 11098, 11099 I changed the following part in jbosspath/server/default/conf/jboss-service.xml: <!-- ==================================================================== --> <!-- JNDI --> <!-- ==================================================================== --> <mbean code="org.jboss.naming.NamingService" name="jboss:service=Naming" xmbean-dd="resource:xmdesc/NamingService-xmbean.xml"> <!-- The call by value mode. true if all lookups are unmarshalled using the caller's TCL, false if in VM lookups return the value by reference. --> <attribute name="CallByValue">false</attribute> <!-- The listening port for the bootstrap JNP service.

The crash happens in the following code, when method str() returns: class JniString { std::string m_utf8; public: JniString(JNIEnv* env, jstring instance) { const char* utf8Chars = env-GetStringUTFChars(instance, 0); if (utf8Chars == 0) { env-ExceptionClear(); // RPF throw std::runtime_error("GetStringUTFChars returned 0"); } m_utf8.assign(utf8Chars); env-ReleaseStringUTFChars(instance, utf8Chars); } std::string str() const { return m_utf8; } }; Simultaneous usage of the two C++ implementations could likely be a reason for the crash, but that should not be happening. Any ideas?
