• Host name resolution on a home network

  - by Kris

  Hi, I have several machines (both virtual and physical) in my internal network at home. Currently I have to connect via 1P addresses. The one main machine I connect with to all the other machines is running Windows Vista. Is there a way I can have some sort of DNS capability inside my network as well so I can refer to these machines with a name? I think this would be a common problem in most households (running a few computers) and I think there might be some simple solutions out there. This would be something most routers should support out of the box - but why don't they? Can anyone recommend some of these or an easy way to accomplish this?

• Filezilla/Puttygen doesn't recognize private key file

  - by devzoner

  I have generated a key for an Ubuntu Virtual Machine running on Azure Cloud Services http://www.windowsazure.com/en-us/manage/linux/how-to-guides/ssh-into-linux/ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout myPrivateKey.key -out myCert.pem When loading the private key into Filezilla, it asks me to convert the format, however, when converting the key it fails, the same happens with puttygen from linux console, using this: puttygen myPrivateKey.key -o myKey.ppk In both cases I have the following error: puttygen: error loading `myPrivateKey.key': unrecognised key type By the way, this key doesn't have a passphrase. I found an old thread about it, but I'm using 0.6.3 version which is newer than what this thread recommends: http://fixunix.com/ssh/541874-puttygen-unable-import-openssh-key.html I've managed to solve this issue by using another gui client Fugu for Mac, but one of my co-worker uses windows and I still have to figure this out. Since Filezilla is the de-facto ftp client, I thought it would be easier to solve it there. Thanks

• Recover OffScreen Window in Windows 8

  - by Jason McD

  Someone asked a very similar question in regards to window recovery for windows xp: Similar Recovery I'm using windows 8 (or 8.1 now). I run Dual Monitors. On Monitor 2 I sometimes have the input switched to something else other than the windows display (Mac or PS3). If there was a program that was displaying on Window #2 that does not have 'move' where I could potentially alt-space-m arrow keys. Is there another way to get that program to display on Window #1? I tried right click on the program and doesn't seem to be anything there. I tried Windows Key and Arrows. I Tried right click toolbar and cascade. I'm hoping this is a DUP or Softball question because this annoys the crap out of me. Thanks!!

• Postfix virtual_alias stealing emails from virutal_mailbox

  - by drewag

  I am trying to setup a "catchall" address. In my virtual_mailbox table I have emails setup like so: select * from virtual_users; id | domain_id | password | email ----+-----------+---------------------------------------------- 3 | 1 | ***************** | [email protected] 4 | 1 | ***************** | [email protected] That works great on its own. When I try to add a virtual alias for the catchall: select * from virtual_aliases; id | domain_id | source | destination ----+-----------+-------------------+--------------------------- 1 | 1 | @domain.com | [email protected] Once I add that virtual_alias, all email is going to catchall and I can send any to [email protected]. Is there something I need to do to shift around the priority? This is what I am getting in my postfix logs: Oct 20 23:24:26 localhost postfix/qmgr[8002]: C23A711DF9: from=<[email protected]>, size=1712, nrcpt=1 (queue active) Oct 20 23:24:26 localhost postfix/lmtp[8148]: C23A711DF9: to=<[email protected]>, orig_to=<[email protected]>, relay=domain.com[private/dovecot-lmtp], delay=0.42, delays=0.4/0.01/0.01/0.01, dsn=2.0.0, status=sent (250 2.0.0 <[email protected]> 8V9DA4q6ZFLVHwAA0J78UA Saved) Oct 20 23:24:26 localhost postfix/qmgr[8002]: C23A711DF9: removed

• How do I set "MaxPermSize" for Atlassian Fisheye/Crucible running as service on Win2k3?

  - by Jeremy

  I have been trying to setup Atlassian Fisheye/Crucible as a service on Win 2K3 R2 for two weeks. I keep getting various "java.lang.OutOfMemoryError: PermGen space" errors, which crash Fisheye and force me to restart the service. I've followed the example on the Atlassian support site to configure MaxPermSize within the service wrapper. However, when I check SysInfo inside the Fisheye Admin pages and the debug log, I don't see any confirmation. The Java Heap info is in both places, so I'd expect the MaxPermSize setting to show up in both places. The error is persisting and Atlassian support has been little help. I appreciate any help.

• network issue ubuntu 8.04 in vmware esx

  - by hoberion

  ok, this is really pissing me off I have one ubuntu 8.04 instance running on vmware (esx) which decided after a reboot to stop resolving dns requests, I also cant connect to it using ssh although I can ping the server and its really that server (when I shutdown the server the ping also stops) stuff I tried: - reboot again :) - nslookup - serverip - setting networking to dhcp - offering some cute kittens to lucifer - removing the virtual nic and adding another (to get a different mac) - migrating the instance to another esx host - drinking 20 cups of espresso - stopped all services - running dnsmasq on another server and connecting to that dns - tcpdumping - disabling ip6 symptoms: cant resolve anything nslookup just says "no servers found..." although I can ping the servers traceroute to gateway doesnt work (even with traceroute -4 -n gatewayip) collegues laughing at me any thoughts

• Nexenta/OpenSolaris filer kernel panic/crash

  - by ewwhite

  I've an x4540 Sun storage server running NexentaStor Enterprise. It's serving NFS over 10GbE CX4 for several VMWare vSphere hosts. There are 30 virtual machines running. For the past few weeks, I've had random crashes spaced 10-14 days apart. This system used to open OpenSolaris and was stable in that arrangement. The crashes trigger the automated system recovery feature on the hardware, forcing a hard system reset. Here's the output from mdb debugger: panic[cpu5]/thread=ffffff003fefbc60: Deadlock: cycle in blocking chain ffffff003fefb570 genunix:turnstile_block+795 () ffffff003fefb5d0 unix:mutex_vector_enter+261 () ffffff003fefb630 zfs:dbuf_find+5d () ffffff003fefb6c0 zfs:dbuf_hold_impl+59 () ffffff003fefb700 zfs:dbuf_hold+2e () ffffff003fefb780 zfs:dmu_buf_hold+8e () ffffff003fefb820 zfs:zap_lockdir+6d () ffffff003fefb8b0 zfs:zap_update+5b () ffffff003fefb930 zfs:zap_increment+9b () ffffff003fefb9b0 zfs:zap_increment_int+68 () ffffff003fefba10 zfs:do_userquota_update+8a () ffffff003fefba70 zfs:dmu_objset_do_userquota_updates+de () ffffff003fefbaf0 zfs:dsl_pool_sync+112 () ffffff003fefbba0 zfs:spa_sync+37b () ffffff003fefbc40 zfs:txg_sync_thread+247 () ffffff003fefbc50 unix:thread_start+8 () Any ideas what this means?

• Setup NTPD in Ubuntu to sync Windows AD

  I am setting up my Ubuntu 10.0.4 server to sync clock with a Windows 2008 AD.

• How can I troubleshoot Windows Media Player being unable to play videos?

  - by Billy ONeal

  I have a Windows Media Player installation which is behaving strangely. I know I have the correct codecs installed for a piece of video, because it is Windows Media Video because the Zune software plays it just fine this is a recent problem; this type of video played just fine a week ago, but I have been unable to isolate the change that borked things (and I have System Restore disabled because the space on this SSD is cramped as it is) When I try to view any video in Windows Media Player, the video does not play, and I just get this: and none of the media buttons have any effect. I have already tried the following: Uninstalling and reinstalling the KLite Codec Pack Uninstalling and reinstalling Windows Media Player via "Add or Remove Windows Features" Removing and allowing WMP to rebuild it's media library by erasing the %LOCALAPPDATA%\Microsoft\Windows Media directory. sfc /scannow How can I troubleshoot this problem?

• What does NT_STATUS_BAD_NETWORK_NAME mean in Samba?

  - by Neil

  I set up a share like this: [global] security = user map to guest = Bad Password usershare allow guests = yes [vms] comment = VirtualBox Virtual Machines path = /home/neil/VirtualBox/HardDisks guest ok = yes read only = yes And when I access the share as myself, and type in my password, it works fine: $ smbclient //neil-ubuntu/vms -U neil Enter neil's password: Domain=[SHUTTERSTOCK] OS=[Unix] Server=[Samba 3.4.0] smb: \> But when I access it as guest, it doesn't work: $ smbclient //neil-ubuntu/vms -U guest Enter guest's password: Domain=[SHUTTERSTOCK] OS=[Unix] Server=[Samba 3.4.0] tree connect failed: NT_STATUS_BAD_NETWORK_NAME Regardless of what password I type in.

• Why did my Cisco router hang?

  - by Mike Pennington

  We have a Cisco 1841 in our storage IDF that was originally running a 12.4(1) IP-BASE image; I wanted to upgrade to an advancedservicesk9-mz image, but the flash did not have enough space, so I deleted the running image. Later I tried inserting a larger CF from a Catalyst4500, which crashed the 1841 router (now without a bootable image). Using another 1800 series router, I loaded the 12.4(25g) advancedservicesk9 image and verified the image checksums. I set the confreg to 0x2102 from rommon and booted the new image; however the 1841 now hangs indefinitely after printing the IOS export control banner. I have tried four other images, all with the same results. What is wrong with this router? UPDATE 1: I tried loading images from a FAT16-formatted USB, but this didn't work either. I also tried tftpdnld from rommon, but got a get_mac_address(): Search T_IDPROM_MACADDR (0xc3) failed Illegal MAC address. error and the file would not load.

• Vertical alignment problem in textbox in Microsoft Word 2007

  - by Surjya Narayana Padhi

  I pardon as its not a programming question at all. But if anybody can answer this it will be usefull for me. In MS word 2007 I drew a textbox and entered some text. Then I right clicked on textbox and went to format shape Then went to TextBox tab and reduced the top internal margin to 0.1 cm. But still it seems there is too much space at the top inside the textbox. I am not able to position the text exactly at the vertical middle of textbox. If I choose the auto-rezide option in format Shape, the textBox size is increases automatically but the text remains exactly at vertical and horizontal middle of textbox. but anyhow I need the textbox to be small. This is very minor but annoying problem. Can anybody help?

• Redirect example.com to www.example.com VPS & Apache2

  - by Thomas Buckley

  I have a VPS and a domain name registered with the provider. When I enter www.example.com my site is displayed correctly, but entering example.com does not work. I am able to ping www.example.com. I added the following line to my apache2 default vhosts file: ServerName example.com ServerAlias www.example.com But this did not work. The VPS is a Debian5 OS. Any ideas? Note: There is no option via a provided control panel to add this, it's a basic package I purchased I know this post answers it but there are no extra comments and I'd like to know if it's the best way: way to redirect page to www using virtual host configuration in sites-available for apache2? Thanks

• Connectivity good between VMs, but no connectivity between host and VM

  - by Greg Sansom

  I have a strange situation where connectivity (ie ping, access shared folders and services) is fine between virtual machines, but not between the host and the virtuals. I've been using Hyper-V almost every day for years and have never had a problem like this. Note the following: The host machine and all virtuals are running Windows Server 2008 r1. All machines can connect to the web, and the gateway router. Subnet mask and gateway reported in ipconfig are identical for all machines. I can access virtuals via the Hyper-V snap-in only. Doea anyone have suggestions about what might be wrong, or what diagnostic steps I can take?

• USB Thumb Drive not recognized in Hyper-V Manager

  - by Vazgen

  I have the free, standalone core Hyper-V Server 2012 running on my physical machine. I set up remote management from my Windows 8 client. When I proceed to create a virtual machine I would like to install the OS from a usb thumb drive but it is not recognized in Hyper-V Manager on my client (when the USB is plugged into the physical server) nor is it recognized in Server Manager under File and Storage Services Volumes Is there a role needed to recognize external usb flash drives? Because I think this standalone version is just core Hyper-V role and that's it... but this is such a basic functionality. Can anybody comment.

• linux ssh -X graphical applications will not start when system load is high

  - by Chrisv

  So I am using ssh -X to access a server. I am at a Xubuntu desktop accessing a Ubuntu server that is in the next room. Usually everything works fine, but when the system load gets high, any graphical applications I have freeze and fail to be restarted. This happens even if the process that is causing the high load has been niced to a low priority with "nice -n 19". And even though the system load is high, the command line works fine with no delay, and other applications I have running on the server (e.g. virtual machines) run fine. But any graphical application running through X dies. When the graphical applications fail they usually give out an error message that suggests a time-out. It seems that something connected to X has a low priority and times out. But what is it, and how does one fix it?

• Cannot add VMDK to VM that was cloned with FlexClone

  - by Daniel Lucas

  I have a virtual machine called VM-A with two VMDK's on volume VOL-A. Call these VMDK-1 (system) and VMDK-2 (data). I want to clone VMDK-2 and attach that clone to VM-A as a new disk, but I'm getting an error. Here are my steps: I use the following command to clone : clone start /vol/VOL-A/VMDK-2 /vol/VOL-A/VMDK-3 Run clone status which shows successful and I can see the new file in the volume In vCenter I edit the settings of VM-A and try to add VMDK-3, but get the following error: Failed to add disk scsi0:4, Failed to power on scsi0:4 I've tried adding this cloned disk to other VMs and get the same error. What could be the issue? My specs are below. NetApp FAS 2040 Data ONTAP 8.0.1 vSphere ESXi 4.1 vCenter Server 4.1 Thanks, Daniel

• Wired and Wireless USB Network Adapter

  - by Evan M.

  Does anyone know if there are any USB network adapters out there that have both wired and wireless networking capability? Far-fetched, I know, but thought I'd ask. Background: Some of our users have locked down laptops that we also include unlocked virtual machines running on VMware Player. Sometimes the users have a need for network connectivity with their VMs where NAT and bridged networking from the host won't work. To supplement this, we want to supply them with adapters that they can use VMware USB pass through capabilities to provide appropriate connectivity. They will need both wired and wireless capability. Rather than carrying around 2 adapters, was hoping we could get a combination unit so that we can reduce it to 1. Thanks

• mkisofs - Floppy Image to Disk Image

  - by CommunistPancake

  I'm trying to compile MikeOS on windows. I've successfully (I think) created a floppy (.flp) image of the operating system. I want to convert it to a disk image (.iso) so I can run it in virtual box. I've tried mkisofs -quiet -V 'MIKEOS' -input-charset iso8859-1 -o disk_images/mikeos.iso -b mikeos.flp disk_images/ Which is the command in the Linux build script. It does create an ISO image, but when I try to run in in VirtualBox, I get a black screen. What am I doing wrong? Here's my build script.

• Static route in conflict with a default route

  Hi guys, I have a default route configured. 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.1 I'd like to add a static route to pass traffic destined for 192.168.1.51 via a load balancer's redundant virtual interface at 192.168.1.2. ip route add 192.168.1.51 mask 255.255.255.255 via 192.168.1.2 When I try to add the static route I get this error. Error: either "to" is duplicate or "default" is garbage." It doesn't want to add the static route because it's in conflict with the default route. Is there a way around this? Regards Ossan

It all works well on a fresh install of Windows 7 without the Intel Chipset drivers installed.

I have a lot of Virtual PC's on the drive and when I start them the disk somewhat disconnects. What could cause this?

• Can / should I prevent my domain controller doing forward lookups for remote users?

  - by markmnl

  I have a Windows Server 2003 server in the office. I VPN into the LAN remotely. My VPN has a virtual NIC with the Windows Server as the primary DNS since it is a domain controller. When connected to the VPN and I do a nslookup or simply browse the web my VPN's DNS (the office's Windows Server) provides the DNS answers - I beleive becuase it has DNS forwarders so queries it cant answer it forwards and then relays the answer. This is the desired behaviour for workstations in the office (they should query their domain controller first). However for remote VPN users this is not desirable - I do not want my remote office's server to answer DNS queries it is not the authority of (which happends to be 192.168.x.x). Is there any way I can configure this?
