  • Using a portable USB monitor in Ubuntu 13.04 (AOC e1649Fwu - DisplayLink)

    Having access to a little bit of IT hardware extravaganza isn't that easy here in Mauritius for exactly two reasons - either it is simply not available or it is expensive like nowhere. Well, by chance I came across an advert by a local hardware supplier and their offer of the week caught my attention - a portable USB monitor. Sounds cool, and the specs are okay as well. It's completely driven via USB 2.0, has a light weight, the dimensions would fit into my laptop bag and the resolution of 1366 x 768 pixels is okay for a second screen. Long story, short ending: I called them and only got to understand that they are out of stock - how convenient! Well, as usual I left some contact details and got the regular 'We call you back' answer. Surprisingly, I didn't receive a phone call as promised and after starting to complain via social media networks they finally came back to me with new units available - and *drum-roll* still the same price tag as promoted (and free delivery on top as one of their employees lives in Flic en Flac). Guess, it was a no-brainer to get at least one unit to fool around with. In worst case it might end up as image frame on the shelf or so... The usual suspects... Ubuntu first! Of course, the packing mentions only Windows or Mac OS as supported operating systems and without hesitation at all, I hooked up the device on my main machine running on Ubuntu 13.04. Result: Blackout... Hm, actually not the situation I was looking for but okay can't be too difficult to get this piece of hardware up and running. Following the output of syslogd (or dmesg if you prefer) the device has been recognised successfully but we got stuck in the initialisation phase.

A quick and dirty research on the net gave me some hints towards the udlfb framebuffer device for USB DisplayLink devices. By default this kernel module is blacklisted $ less /etc/modprobe.d/blacklist-framebuffer.conf | grep udl#blacklist udlblacklist udlfb and it is recommended to load it manually. So, unloading the whole udl stack and giving udlfb a shot: Oct 12 08:22:31 iospc2 kernel: [70126.642809] usbcore: registered new interface driver udlfb But still no reaction on the external display which supposedly should have been on and green. Display okay? Test run on Windows Just to be on the safe side and to exclude any hardware related defects or whatsoever - you never know what happened during delivery. I moved the display to a new position on the opposite side of my laptop, installed the display drivers first in Windows Vista (I know, I know...) as recommended in the manual, and then finally hooked it up on that machine. Tada! Display has been recognised correctly and I have a proper choice between cloning and extending my desktop. Testing whether the display is working properly - using Windows Vista Okay, good to know that there is nothing wrong on the hardware side just software... Back to Ubuntu - Kernel too old Some more research on Google and various hits recommend that the original displaylink driver has been merged into the recent kernel development and one should manually upgrade the kernel image (and both header) packages for Ubuntu. At least kernel 3.9 or higher would be necessary, and so I went out to this URL: http://kernel.ubuntu.com/~kernel-ppa/mainline/ and I downloaded all the good stuff from the v3.9-raring directory. The installation itself is easy going via dpkg: $ sudo dpkg -i linux-image-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb$ sudo dpkg -i linux-headers-3.9.0-030900_3.9.0-030900.201304291257_all.deb$ sudo dpkg -i linux-headers-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb As with any kernel upgrades it is necessary to restart the system in order to use the new one. Said and done: $ uname -r3.9.0-030900-generic And now connecting the external display gives me the following output in /var/log/syslog: Oct 12 17:51:36 iospc2 kernel: [ 2314.984293] usb 2-4: new high-speed USB device number 6 using ehci-pciOct 12 17:51:36 iospc2 kernel: [ 2315.096257] usb 2-4: device descriptor read/64, error -32Oct 12 17:51:36 iospc2 kernel: [ 2315.337105] usb 2-4: New USB device found, idVendor=17e9, idProduct=4107Oct 12 17:51:36 iospc2 kernel: [ 2315.337115] usb 2-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3Oct 12 17:51:36 iospc2 kernel: [ 2315.337122] usb 2-4: Product: e1649FwuOct 12 17:51:36 iospc2 kernel: [ 2315.337127] usb 2-4: Manufacturer: DisplayLinkOct 12 17:51:36 iospc2 kernel: [ 2315.337132] usb 2-4: SerialNumber: FJBD7HA000778Oct 12 17:51:36 iospc2 kernel: [ 2315.338292] udlfb: DisplayLink e1649Fwu - serial #FJBD7HA000778Oct 12 17:51:36 iospc2 kernel: [ 2315.338299] udlfb: vid_17e9&pid_4107&rev_0129 driver's dlfb_data struct at ffff880117e59000Oct 12 17:51:36 iospc2 kernel: [ 2315.338303] udlfb: console enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338306] udlfb: fb_defio enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338309] udlfb: shadow enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338468] udlfb: vendor descriptor length:17 data:17 5f 01 0015 05 00 01 03 00 04Oct 12 17:51:36 iospc2 kernel: [ 2315.338473] udlfb: DL chip limited to 1500000 pixel modesOct 12 17:51:36 iospc2 kernel: [ 2315.338565] udlfb: allocated 4 65024 byte urbsOct 12 17:51:36 iospc2 kernel: [ 2315.343592] hid-generic 0003:17E9:4107.0009: hiddev0,hidraw5: USB HID v1.10 Device [DisplayLink e1649Fwu] on usb-0000:00:1d.7-4/input1Oct 12 17:51:36 iospc2 mtp-probe: checking bus 2, device 6: "/sys/devices/pci0000:00/0000:00:1d.7/usb2/2-4"Oct 12 17:51:36 iospc2 mtp-probe: bus: 2, device: 6 was not an MTP deviceOct 12 17:51:36 iospc2 kernel: [ 2315.426583] udlfb: 1366x768 @ 59 Hz valid modeOct 12 17:51:36 iospc2 kernel: [ 2315.426589] udlfb: Reallocating framebuffer.

The external USB display works out-of-the-box with a Linux kernel > 3.9.0. Despite of a good number of resources it is absolutely not necessary to create a Device or Screen section in one of Xorg.conf files. This information belongs to the past and is not valid on kernel 3.9 or higher. Same hardware but Windows 8 Of course, I wanted to know how the latest incarnation from Redmond would handle the new hardware... Flawless! Most interesting aspect here: I did not use the driver installation medium on purpose. And I was right... not too long afterwards a dialog with the EULA of DisplayLink appeared on the main screen. And after confirmation of same it took some more seconds and the external USB monitor was ready to rumble. Well, and not only that one... but see for yourself. This time Windows 8 was the easiest solution after all. Resume I can highly recommend this type of hardware to anyone asking me. Although, it's dimensions are 15.6" it is actually lighter than my Samsung Galaxy Tab 10.1 and it still fits into my laptop bag without any issues. From now on... no more single screen while developing software on the road!

  • Ubuntu 10.04 & IBM DS3524 with FC multipath, inactive path is [failed][faulty] instead of [active][ghost]

    - by Graeme Donaldson
    OK, this is my setup: FC Switches IBM/Brocade, Switch1 and Switch2, independent fabrics. Server IBM x3650 M2, 2x QLogic QLE2460, 1 connected to each FC Switch.

I assume that once I can get that right then the spam in my syslog will end as well. One final thing worth mentioning is that the IBM redbook doc targets SLES 11 so I'm assuming there's something a little different under Ubuntu that I just haven't figured out yet. Update: As suggested by Mitch, I've tried removing /etc/multipath.conf, and now the output of multipath -ll looks like this: root@db06:~# multipath -ll sdg: checker msg is "directio checker reports path is down" sdh: checker msg is "directio checker reports path is down" xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxdm-1 IBM ,1746 FASt [size=4.9T][features=0][hwhandler=0] \_ round-robin 0 [prio=1][active] \_ 5:0:2:0 sde 8:64 [active][ready] \_ round-robin 0 [prio=1][enabled] \_ 5:0:1:0 sdd 8:48 [active][ready] \_ round-robin 0 [prio=0][enabled] \_ 6:0:1:0 sdg 8:96 [failed][faulty] \_ round-robin 0 [prio=0][enabled] \_ 6:0:2:0 sdh 8:112 [failed][faulty] So its more or less the same, with the same message in the syslog every 5 minutes as before, but the grouping has changed.

  • Why is my machine unable to mount my SMB drives ("CIFS VFS: Error connecting to socket. Aborting operation", return code -115)?

    - by downbeat
    I have a machine running Precise (12.04 x64), and I cannot mount my SMB drives (I have 3, we'll call them public, private and download). It used to work (a week or two ago) and I didn't touch fstab! The machine hosting the shares is a commercial NAS, and I'm not seeing anything that would indicate it's an issue with the NAS. I have an older machine which I updated to Precise at the same time (both fresh installed, not dist-upgrade), so should have a very similar configuration. It is not having any problems. I am not having problems on windows machines/partitions either, only one of my Precise machines. The two machines are using identical entries in fstab and identical /etc/samba/smb.conf files. I don't think I've ever changed smb.conf (has never mattered before). My fstab entries all basically look like this: //10.1.1.111/public /media/public cifs credentials=/home/downbeat/.credentials,iocharset=utf8,uid=downbeat,gid=downbeat,file_mode=0644,dir_mode=0755 0 0 Here's the dmesg output on boot: [ 51.162198] CIFS VFS: Error connecting to socket. Aborting operation [ 51.162369] CIFS VFS: cifs_mount failed w/return code = -115 [ 51.194106] CIFS VFS: Error connecting to socket. Aborting operation [ 51.194250] CIFS VFS: cifs_mount failed w/return code = -115 [ 51.198120] CIFS VFS: Error connecting to socket. Aborting operation [ 51.198243] CIFS VFS: cifs_mount failed w/return code = -115 There are no other errors I see in the dmesg output. Originally when I ran 'testparm -s', the output contained these lines ERROR: lock directory /var/run/samba does not exist ERROR: pid directory /var/run/samba does not exist Here's the samba related programs I have installed: $ dpkg --list|grep -i samba ii libpam-winbind 2:3.6.3-2ubuntu2.3 Samba nameservice and authentication integration plugins ii libwbclient0 2:3.6.3-2ubuntu2.3 Samba winbind client library ii nautilus-share 0.7.3-1ubuntu2 Nautilus extension to share folder using Samba ii python-smbc 1.0.13-0ubuntu1 Python bindings for Samba clients (libsmbclient) ii samba-common 2:3.6.3-2ubuntu2.3 common files used by both the Samba server and client ii samba-common-bin 2:3.6.3-2ubuntu2.3 common files used by both the Samba server and client ii winbind 2:3.6.3-2ubuntu2.3 Samba nameservice integration server $ dpkg --list|grep -i smb ii dmidecode 2.11-4 SMBIOS/DMI table decoder ii libsmbclient 2:3.6.3-2ubuntu2.3 shared library for communication with SMB/CIFS servers ii python-smbc 1.0.13-0ubuntu1 Python bindings for Samba clients (libsmbclient) ii smbclient 2:3.6.3-2ubuntu2.3 command-line SMB/CIFS clients for Unix ii smbfs 2:5.1-1ubuntu1 Common Internet File System utilities - compatibility package $ dpkg --list|grep -i cifs ii cifs-utils 2:5.1-1ubuntu1 Common Internet File System utilities ii libsmbclient 2:3.6.3-2ubuntu2.3 shared library for communication with SMB/CIFS servers ii smbclient 2:3.6.3-2ubuntu2.3 command-line SMB/CIFS clients for Unix I originally noticed that my other machine had "libpam-winbind" and "nautilus-share" installed and the machine with the issue did not. Installing those two packages solved my errors with 'testparm -s', but did not fix my issue. Finally, I tried to purge and reinstall these packages smbclient smbfs cifs-utils samba-common samba-common-bin Still no luck. Again, it used to work; now it doesn't. Very similarly configured machine works (but some packages are out of date on the working machine). The NAS has only one interface/IP address, nmblookup works to find it's IP from it's hostname (from the machine with the issue) and it responds to a ping. Please any help would be great. I've been searching on AskUbuntu, SuperUser, ubuntuforums and plain old search engines for a week now and it's driving me crazy!

  • Ubuntu 12.04 lightdm dumps to tty. Cannot start GUI interface when booting off harddrive, but can when booting off usb

    - by user72681
    When booting, lightdm dumps to tty. No GUI interface works- this is after a fresh install of Ubuntu 12.04 where the GUI interface works when running off the USB.

  • How to reduce RAM consumption when my server is idle

    - by Julien Genestoux
    We use Slicehost, with 512MB instances. We run Ubuntu 9.10 on them. I installed a few packages, and I'm now trying to optimize RAM consumption before running anything on there.

Quite disapointing! 2 questions arise : Where is all this memory? How to take some of it back for my own apps?

  • virtual host not working in windows7 xampp

    - by K.B Panamaldeniya-littletipz
    hi i am using windows7 and xampp , i want to create a virtual host . so i added 127.0.0.1 myawesomeproject to my C:\Windows\System32\drivers\etc\hosts like this # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. 127.0.0.1 localhost 127.0.0.1 myawesomeproject ::1 localhost and i added some lines to C:\xampp\apache\conf\extra\httpd-vhosts.conf like this # # Virtual Hosts # # If you want to maintain multiple domains/hostnames on your # machine you can setup VirtualHost containers for them. Most configurations # use only name-based virtual hosts so the server doesn't need to worry about # IP addresses.

  • Converting a PV vm back into an HVM vm

    - by wim.coekaerts
    I have been doing some Oracle VM benchmark stuff in the last week or 2 in my off hours and yesterday I wanted to convert one of my VMs that was based on a paravirt kernel into a vm that just boots as a regular hardware virt VM with a standard x86-64 kernel. It took me a little while to figure out the fastest way so now that I have it pretty much down I wanted to share the steps. A PV kernel uses pygrub and a paravirt kernel image that lives on the vm image virtual disk. since this disk image does not have to be bootable it doesn't contain a boot sector and if you just restart the VM in hvm mode the virtual bios will just not do much as it can't start the boot process from disk The first thing I do is make a backup of my vm.cfg file :-) and then edit it as follows : the original file contains : bootloader = '/usr/bin/pygrub' I replace that with : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' kernel = '/usr/lib/xen/boot/hvmloader' then changing the disk files. I change my xvd disks to hd disks and I copy over the iso image of my instal lDVD. In the case of my VM template it was based on OL5U4 So I downloaded Enterprise-R5-U4-Server-x86_64-dvd.iso and added it as a cd device. disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,xvda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,xvdb,w', ] to disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,hda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,hdb,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Enterprise-R5-U4-Server-x86_64-dvd.iso, hdc:cdrom,r', ] boot='d' for the network devices (vifs) I change : vif = ['bridge=xenbr2,type=netfront'] to vif = ['bridge=xenbr2,type=ioemu'] That should do it. Next, inside the VM, I copy over the regular kernel rpm that I want to end up running in hvm mode. In this example case it was : kernel-2.6.18-164.0.0.0.1.el5.x8664.rpm. I will use that later on in the process. I put this kernel simply in /root At this point I just start the vm with xm create vm.cfg and start my vnc console to the vm console. Oracle Linux will boot from the iso image, I just go through the install steps and click on UPgrade existing (not re-install). Because the VM is the same as the ISO the install won't actually do anything and it will run through instantly. When the "Reboot" button pops up, don't reboot. Switch to the command prompt console. hi alt-f2 to go to the shell prompt. Now it's easy : umount /mnt/sysimage/boot cd /mnt/sysimage chroot . mount /dev/hda1 (if that was your /boot partition) export PATH=/sbin:$PATH (just to clean that up) edit /etc/modprobe.conf and comment out the xen modules (just put a # in front) Install grub. if your /boot is hda1 then that is (hd0,0) $ grub root (hd0,0) setup (hd0) exit grub now you have a good bootsector, grub installed and you have your grub.conf file Install the new kernel cd root (this is your old /root in your pv image) rpm -ivh remove (or comment out) boot='d' in your vm.cfg restart the VM and you should be good to go, regular grub should start and load your environment. Caveats : this assumes you used labels for your filesystems. if /etc/fstab were to have devices listed then you would have to rename these device before rebooting as well. If you had a /dev/xvda disk then this would be /dev/hda or /dev/sda. All in all it is a relatively short and simple process.

  • Ubuntu 10.04 and fedora 14 grub conflict

    - by sawren
    I tried to triple boot Windows xp, Fedora 14 and Ubuntu 10.04. I first installed Windows xp, then fedora followed by Ubuntu. The problem is that i don't get option to boot Ubuntu while Xp boots fine. It seems Ubuntu was unable to replace Fedora's grub with its own at MBR. Looking at their grub conf file, Fedora and Ubuntu identifies same harddisk as two different devices and i do have another 80 GB harddisk which doesn't have any OS.

    Originally posted on: http://geekswithblogs.net/Aligned/archive/2014/05/30/notes-from-a-short-presentation-on-nodejs.aspxI volunteered myself to give a short 30 minute presentation at a work lunch and learn on NodeJs. With my limited experience I see using Node as a great tool for build process improvement, scaffolding with yeoman, and running tests with Karma. I haven’t looked into using as a full server or development stack. I guess I’m too stuck on IIS and Visual Studio :-).

"Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

  • disks not ready in array causes mdadm to force initramfs shell

    - by RaidPinata
    Okay, this is starting to get pretty frustrating. I've read most of the other answers on this site that have anything to do with this issue but I'm still not getting anywhere. I have a RAID 6 array with 10 devices and 1 spare. The OS is on a completely separate device. At boot only three of the 10 devices in the raid are available, the others become available later in the boot process. Currently, unless I go through initramfs I can't get the system to boot - it just hangs with a blank screen. When I do boot through recovery (initramfs), I get a message asking if I want to assemble the degraded array. If I say no and then exit initramfs the system boots fine and my array is mounted exactly where I intend it to. Here are the pertinent files as near as I can tell. Ask me if you want to see anything else. # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default (built-in), scan all partitions (/proc/partitions) and all # containers for MD superblocks. alternatively, specify devices to scan, using # wildcards if desired. #DEVICE partitions containers # auto-create devices with Debian standard permissions # CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR root # definitions of existing MD arrays # This file was auto-generated on Tue, 13 Nov 2012 13:50:41 -0700 # by mkconf $Id$ ARRAY /dev/md0 level=raid6 num-devices=10 metadata=1.2 spares=1 name=Craggenmore:data UUID=37eea980:24df7b7a:f11a1226:afaf53ae Here is fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

I just can't seem to figure out how to change the boot process so that mdadm waits until the drives are ready to build the array. Everything works just fine if the drives are given enough time to come online. edit: changed title to properly reflect situation

  • How to fix: Ubuntu 12.04 reboots after loading with elilo

    - by Casey
    I have an HP p6-2120 with CPU: AMD A6-3620 APU with Radeon Graphics RAM: 6GB BIOS: HO2_710.ROM v7.10 [AMI v7.10 4/19/2012] Disk: SATA1 (/dev/sda) - 1 TB (windows) Disk: SATA2 (/dev/sdb) - 1 TB partitioned using "parted -a optimal /dev/sdb" as follows: .. 1049KB 201MB FAT32 boot flag set .. 201MB 60GB ext2 (/) .. 68GB 78GB linux-swap(v1) (swap) .. 78GB 790GB ext4 (/home) .. - rest is "free" space reserved for other purposes (eventually) ubuntu: 12.04.1 LTS [specifically: Release 12.04 (precise) 64-bit] kernel: linux 3.2.0-29-generic I created a bootable EFI USB from the ISO (64-bit) which I downloaded. I can run and install from the USB without any problems. The BIOS is an EFI bios that appears to be capable of booting in either EFI or Legacy mode. Initially, I did the "standard" install with NOTHING on disk2, and let the installer configure everything. The net result of this was that when I started the computer and forced it into "boot" menu mode, it DOES NOT recognize SATA2 as an EFI drive, and when I attempt to "legacy" boot from it, I get the message "ERROR: No Boot Disk has been detected." The "standard" install created one large partition that consumed the entire disk. At that point, I manually partitioned the disk (using sudo parted -a optimal /dev/sdb) as described above. I selected the "other" install, and changed the /dev/sdb1 to "bios_grub", /dev/sdb2 as "/" (ext4), /dev/sdb3 as swap, and /dev/sdb4 as "/home". [Note: fearing that possibly elilo did not recognize ext4, I switched /dev/sdb2 to ext2 and re-insalled] The net result was that the install appeared to trash the /dev/sdb1 partition so that it was NOT readable by anything. I re-formated /dev/sdb1 as FAT32 and set the boot flag. I repeated the install ignoring the messages about no bios_grub partition. After several attempts to get GRUB2 to work, I switched to elilo. I downloaded the most recent version and copied it (elilo-3.14-ia64.efi) to /dev/sdb1/efi/boot/bootx64.efi. (The BIOS boot loader did not recognize it either as elilo-3.14.ia64.efi or as elilo.efi. Based on the advice in one of the web-pages I found, I renamed it to bootx64.efi. This worked.) In that same directory (/efi/boot), I copied the file pointed to the link in /dev/sdb2/vmlinuz to /efi/boot/vmlinuz, and the file pointed to the link in /dev/sdb2/initrd.img to /efi/boot/initrd.img. I created an elilo.conf file as follows: timeout=5000 prompt default=linux-boot image=vmlinuz label=linux-boot read-only initrd=initrd.img root=/dev/sdb2 The /efi/boot directory contains 4 files: bootx64.efi elilo.conf vmlinuz initrd.img When I power-cycle the computer and force the boot menu, drive2 shows up as an EFI bootable drive. When I select it, I get the elilo prompt. Pressing , it appears to load the kernal (I have tried it with verbose=5, and there is a long string of messages with the final one a command line to load the kernel and a series of several dots that fly by) then the screen goes blank, and it reboots the computer. [Note: I have also tried substituting the UUID as found in the /etc/fstab of the installed system for the root directory. This had no effect.] This is a brief synopsis of several nights of fiddling with this. I would deeply appreciate any help you can give.

  • DNS resolution problems; dig SERVFAIL error

    - by JustinP
    I'm setting up a couple of dedicated servers, and having problems setting up my nameservers properly. One of these is a LEMP server (LAMP with nginx in place of Apache), and the other will function solely as an email server, running exim/dovecot/ASSP antispam (no Apache). The LEMP server is CentOS 5.5, with no control panel, while the email server is CentOS 5.5 as well, with cPanel/WHM. So, I've had problems getting DNS set up properly. I have two domains, each one pointing to one of these servers. The nameservers are registered correctly with the domain registrar, and the nameserver IPs are entered correctly as well. I've spoken to tech support at the registrar and they confirm that everything is set up on their end. Not knowing much about DNS, I googled nameservers and DNS until I nearly went blind, and spent hours messing with the configuration. Eventually, I got the LEMP server's DNS working properly (no cPanel). Pleased with this triumph, I'm trying to mimic that configuration and repeat the process with the email server, and it's just not happening. The nameserver starts and stops, but the domain doesn't resolve. Things I have tried Going through standard procedures to set up DNS in WHM Clearing all DNS information, uninstalling BIND, then reinstalling all of that and again going through WHM procedures for setting up DNS Clearing all DNS information, and setting up BIND via shell (completely outside of cPanel) by using my config and zone files from the LEMP server as a template named runs just fine, but nothing is resolving. When I "dig any example.com" I get a SERVFAIL message. Nslookups return no information. Here are my config and zone files. named.conf controls { inet 127.0.0.1 allow { localhost; } keys { coretext-key; }; }; options { listen-on port 53 { any; }; listen-on-v6 port 53 { ::1; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; // Those options should be used carefully because they disable port // randomization // query-source port 53; // query-source-v6 port 53; allow-query { any; }; allow-query-cache { any; }; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; view "localhost_resolver" { match-clients { 127.0.0.0/24; }; match-destinations { localhost; }; recursion yes; //zone "."

Tech support is very responsive, and largely useless. Hours go by with them asking me questions to narrow down what could be wrong, then they pass the ticket to the tech on the next shift, who ignores everything that's happened already and spend his whole shift asking all the same questions the last guy asked. So, in summary: *Nameservers, with IPs, are correctly registered with domain registrar *named is configured and running *...and must not be configured correctly, because nothing resolves. Any help would be great. I changed domains and IPs in the files to generics, but let me know if you need to know the domain in question. Thanks! UPDATE I found that I didn't have 127.0.0.1 in /etc/resolv.conf, so I added it, along with my two public IPs that I have named listening on. resolv.conf search www.example.com example.com nameserver 127.0.0.1 nameserver 7.8.9.10 ;Was in here by default, authoritative nameserver of hosting company nameserver 1.2.3.4 ;Public IP #1 nameserver 1.2.3.5 ;Public IP #2 Now when I DIG example.com from the host, it resolves. If I try to DIG from my other server (in the same datacenter), or from the internet, it times out or I get SERVFAIL.

  • svn: unknown hostname for hostname that does indeed exist

  • How can I run BitchX when I don't have ssh or shell access?

    I just installed an IRC bot, B****X (Don't ask, I don't know - the real name is not censored). I did all of the configuration and chmod'ed the pl files to 755, but running it won't work.

  • django+uploadify - don't working

    Hi, I'm trying to use an example posted on the "github" the link is http://github.com/tstone/django-uploadify. And I'm having trouble getting work. can you help me?

  • apache: cgi links lead to a "you have chosen to open foo.cgi", although scriptalias is set

    - by Xiong Chiamiov
    Following this guide on CentOS 5.2, just getting nagios set up for the first time. The main page shows up just fine, but when I try to view any of the pages that should be generated by a cgi process, firefox prompts me to save the .cgi instead, so apache's obviously not understanding that it needs to run the cgi and get back some html from it. The odd thing is, though, that, as far as I can tell, apache should be running these files as cgi. nagios.conf: # SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER # Last Modified: 11-26-2005 # # This file contains examples of entries that need # to be incorporated into your Apache web server # configuration file. Customize the paths, etc. as # needed to fit your system. ScriptAlias /nagios/cgi-bin/ "/usr/lib/nagios/cgi/" # SSLRequireSSL Options +ExecCGI AddHandler cgi-script .cgi AllowOverride None Order allow,deny Allow from all # Order deny,allow # Deny from all # Allow from 127.0.0.1 AuthName "Nagios Access" AuthType Basic AuthUserFile /etc/nagios/htpasswd.users Require valid-user Alias /nagios "/usr/share/nagios/" # SSLRequireSSL DirectoryIndex index.php Options None AllowOverride None Order allow,deny Allow from all # Order deny,allow # Deny from all # Allow from 127.0.0.1 AuthName "Nagios Access" AuthType Basic AuthUserFile /etc/nagios/htpasswd.users Require valid-use Either the ScriptAlias directive or ExecCGI option should be triggering this, but neither of them seems to have any effect. This config file is being parsed by apache, because if I move it out of conf.d, /nagios gives a 404. The .cgi files are indeed in the /nagios/cgi-bin/ directory, so I didn't specify the incorrect directory. Searching seemed to only provide people who had difficulty with permissions, which is not the issue here. This seems to me to be a pretty basic thing, but even with the excellent apache documentation, I'm at a bit of a loss (been using cherokee too much lately :) ).

  • Finding JNP port in JBoss from Servlet

    - by Steve Jackson
    I have a servlet running in JBoss (4.2.2.GA and 4.3-eap) that needs to connect to an EJB to do work. In general this code works fine to get the Context to connect and make RMI calls (all in the same server). public class ContextFactory { public static final int DEFAULT_JNDI_PORT = 1099; public static final String DEFAULT_CONTEXT_FACTORY_CLASS = "org.jnp.interfaces.NamingContextFactory"; public static final String DEFAULT_URL_PREFIXES = "org.jboss.naming:org.jnp.interfaces"; public Context createContext(String serverAddress) { //combine provider name and port String providerUrl = serverAddress + ":" + DEFAULT_JNDI_PORT; //Set properties needed for Context: factory, provider, and package prefixes. Hashtable<String, String> env = new Hashtable<String, String>(3); env.put(Context.INITIAL_CONTEXT_FACTORY, DEFAULT_CONTEXT_FACTORY_CLASS); env.put(Context.PROVIDER_URL, providerUrl); env.put(Context.URL_PKG_PREFIXES, DEFAULT_URL_PREFIXES); return new InitialContext(env); } Now, when I change the JNDI bind port from 1099 in server/conf/jboss-service.xml I can't figure out how to programatically find the correct port for the providerUrl above. I've dumped System.getProperties() and System.getEnv() and it doesn't appear there. I'm pretty sure I can set it in server/conf/jndi.properties as well, but I was hoping to avoid another magic config file. I've tried the HttpNamingContextFactory but that fails "java.net.ProtocolException: Server redirected too many times (20)" env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.HttpNamingContextFactory"); env.put(Context.PROVIDER_URL, "http://" + serverAddress + ":8080/invoker/JNDIFactory"); Any ideas?

  • RapidXML, reading and saving values

    - by Layne
    Hello, I've worked myself through the rapidXML sources and managed to read some values. Now I want to change them and save them to my XML file: Parsing file and set a pointer void SettingsHandler::getConfigFile() { pcSourceConfig = parsing->readFileInChar(CONF); cfg.parse<0>(pcSourceConfig); } Reading values from XML void SettingsHandler::getDefinitions() { SettingsHandler::getConfigFile(); stGeneral = cfg.first_node("settings")->value(); /* stGeneral = 60 */ } Changing values and saving to file void SettingsHandler::setDefinitions() { SettingsHandler::getConfigFile(); stGeneral = "10"; cfg.first_node("settings")->value(stGeneral.c_str()); std::stringstream sStream; sStream << *cfg.first_node(); std::ofstream ofFileToWrite; ofFileToWrite.open(CONF, std::ios::trunc); ofFileToWrite << "<?xml version=\"1.0\"?>\n" << sStream.str() << '\0'; ofFileToWrite.close(); } Reading file into buffer char* Parser::readFileInChar(const char* p_pccFile) { char* cpBuffer; size_t sSize; std::ifstream ifFileToRead; ifFileToRead.open(p_pccFile, std::ios::binary); sSize = Parser::getFileLength(&ifFileToRead); cpBuffer = new char[sSize]; ifFileToRead.read( cpBuffer, sSize); ifFileToRead.close(); return cpBuffer; } However, it's not possible to save the new value. My code is just saving the original file with a value of "60" where it should be "10". Rgds Layne
