• USB MFP print server that works with Windows x64?

  - by hangy

  Right now, we are using the Longshine LCS-MFP101-2 to connect to our MFP device (printer/scanner combo) over LAN. However, the required driver (RMVUSB, Remote Virtual USB) cannot be installed on 64 bit Windows operating systems such as Windows XP x64 or Windows 7 x64. Since the distributor lists the product as "phased out", I do not expect any updated 64 bit drivers any time soon. :/ Because of that, I am searching for a relatively cheap SOHO MFP print server (1 USB port should be enough) which can be used with 32 bit and 64 bit versions of Windows. Do you have any ideas or recommendations? Thanks!

• Where is Amazon Linux AMI Test Page EC2?

  - by fuzzybee

  I have set up my websites as directories directly under /var/www/html/ and they are working just fine (the websites are mapped to virtual hosts). So, this is mainly out of curiosity for the moment. Furthermore, being able to customise this might bring some benefits in the future e.g. branding the elastic IPs my computer use temporarily. Notes I can always create a index.html page under /var/www/html/ and modify it but that's not my goal here. I can also map the elastic IP address to a directory /var/www/html/default/ and do my stuffs there but that is not also my goal here My goal is the find the Amazon Linux AMI test page I've tried running Linux command to find it but it takes too long obviously

• QoS / PBR Routing Questions

  - by Bernard

  I have a 50Mbs Satellite link and a 10Mbs Microwave link supplying a very remote location. Behind these links, I have a 6,400 seat network - with about 3,000 signed in at any one time. My goal is to send all of the Voip traffic (Google Chat, Magic Jack, Skype, Speakeasy, Vonage, Vonage PC, Yahoo) through the microwave link which has 100ms latency. The rest of the traffic can utilize any remaining bandwidth of the microwave link with excess being diverted to the higher latency (600ms) satellite connection. The problem I've had so far is that most automatic routing configurations weigh the bandwidth heavily for preference - and I'm only wanting latency considered. Additionally, I don't know if this can even be handled with the routing hardware I have at my disposal (Cisco 3640, 3745, & 3845). Any recommendations (or really good starting points) would be greatly appreciated.

• 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

• KVM online disk resize?

  - by Eil

  We're evaluting KVM for Linux virtualization on a few projects. All is going well so far. But one of our requirements is the ability to add disk space to a running guest without rebooting or taking it offline. Is this possible with KVM? The only thing I've found so far (but have not tested yet) is the ability to hotplug disks into the machine. If I go this route, then I could always add the new disk to an LVM volume group on the guest and then extend the chosen logical volume. The biggest downside to this approach is that over time we might end up with guests having variable numbers of virtual disks. The "real" disk space would be provided to the host over a SAN, so we can always add more space to the host whenever.

• Sonicwall networking

  - by Syed

  My Sonicwall LAN subnet is 192.168.1.0/24 X0: LAN IP 192.168.1.253 I also have intranet router 192.168.1.108 routing to 192.168.2.0/24 network. Internet is through WAN (X1) is all working fine. My LAN PC's can connect to intranet 192.168.2.0/24 via static route from LANsubnet to 192.168.2.0/24 as 192.168.1.108 as gateway. Now I have LAN2 10.2.1.254 (10.2.1.0/24)on X4 port. I can access Internet from LAN2, now I want to allow intranet from LAN2. What static routes do I need to make this work?

• Cannot access Tomcat application remotely, but can access Apache applications

  - by David Keaveny

  I am installing Atlassian's Confluence 4.2 on a clean Ubuntu 12.04 server. Confluence runs on Tomcat 6, and uses PostgreSQL 9.1 as its datastore. I've installed and configured phpPgAdmin to manage PostgreSQL, and Zentyal to manage the server generally. Both these applications use Apache. The problem that I am experiencing is that while I can access phpPgAdmin and Zentyal without problem from a remote PC, I can only access Confluence when running locally (either specified by localhost, IP address or host name). Instead I get an HTTP 502 Connection Failed error. By way of experimentation, I also installed Ajenti, which appears to use lighttpd rather than Apache or Tomcat, and it too works fine when connected to locally, but gives me the same HTTP 502 error when connected to remotely. So applications served from Apache work fine, but applications served from other services do not - does that ring a bell with anyone? It's been over 10 years since I last sysadmin'ed a Linux box, so I'm more than a little rusty!

• Static route in conflict with a default route

  - by Ossan Sokiv

  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

• Core Audio sound driver has an error

  - by Raj More

  I have been using Virtual DJ on my machine. The setup is where I want audio to play over the headphones and use a USB sound card to play audio into my headphones so I can listen to music before I play it for everybody. However, the last time I tried, I got an error message saying "Error in the sound driver of Core Audio. Your sound card is probably not connected, or the settings are incorrect". If I use the headphone by themselves, the USB sound card by itself, or my speakers by themselves, they all work individually. How do I go about figuring out what's wrong here?

• OpenVPN on Android TCP retransmissions after OpenVPN server reboot

  - by anogaki

  I raised OpenVPN on server for the first time. It worked fine until the server rebooted. The firewall configuration is unchanged. When I tcpdump from tun interface on the server, I always get TCP retransmissions on all TCP packets larger than a few bytes in Android. Using a similar(read: same) configuration on my Linux box from where I'm posting this message now works just fine; no retransmissions, no loss. It did work just fine before the server rebooted. What could possibly cause this? I already tried rebooting Android, it didn't help. Client configuration, used on both Linux PC and Android tablet: dev tun client remote 192.168.0.1 persist-key persist-tun nobind pkcs12 user.p12 mssfix 1480 cipher AES-256-CBC verb 3 1480 is below the mtu of uplink connection on server which is 1492. I tried adding tun-mtu 1480 to Android but that didn't help either.

• How to get headphones and speakers working at the same time?

  - by Borek

  I have a Gigabyte P55-UD3 motherboard which comes with a Realtek sound card and audio header for the front panel. My headset is permanently connected to the front panel (mic in, headphones in) and I also have speakers connected at the rear of the computer. What I want to achieve is that both the headphones and the speakers work at the same time. On my old PC with Realtek, I was able to do this by clicking "Device advanced settings" in the Realtek HD Audio Manager and then clicking "Make front and rear output devices playback two different audio streams simultaneously" and then doing some reassigning of front/rear settings in the Realtek Audio Manager (can't remember the details). But that doesn't seem to be working now - either the speakers play sounds or the headphones, not both at the same time. To pose the question differently, Windows plays the sounds on the "default device". I'd like to make both headphones and the speakers kind of like the default devices.

• 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

• Add linux user with restricted access

  - by Dominik Str

  I need to create a user on linux with access rights only to one folder. Background: I have installed git on my virtual server (Debian). I also created a user for the repository. There is a lot of private data on the server. But all folders have read-access for others, because it's needed for the applications which run on the server. So the git-user can see all the data. I would like to restrict the git user only to the folder where the repository is installed. I also tried ACL, but it didn't work. Is there a better way to do this? Thanks in advance!

• 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.

• 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?

• Installing Intel Rapid Storage Drivers makes my eSATA Drives act weird

  - by Filip Ekberg

  I have a HP 8530w Elitebook this Laptop got an eSATA port which I want to plug my LaCie d2 Quadra V2 1TB harddrive into. It all works well on a fresh install of Windows 7 without the Intel Chipset drivers installed. However when I install the Intel Rapid Storage drivers or the Intel Matrix software my drive seems to "disconnect" when I use it to much. I have a lot of Virtual PC's on the drive and when I start them the disk somewhat disconnects. What could cause this?

• Resolving DNS queries for two disconnected, private, networks

  - by Mikeage

  I'm trying to setup two PCs (one Windows, one Linux, but my understanding is that this problem is more DNS and less OS) as follows: Home network: 192.168.1.0/24 VPN (via OpenVPN server not within the home network): 192.168.2.0/24 . I would like a PC on both networks to be able to access three different types of site: Internet addresses Addresses on the home network Addresses on the vpn However, I'm not sure how/which DNS servers to use. If I prioritize my home DNS server, I can resolve (1) and (2), but not (3). If I prioritize my VPN DNS server, I can't resolve addresses of type (2). Of course, looking up addresses via nslookup and explicitly setting the correct server works, so I know my local DNS servers are OK. Is there any way I can set up my PCs to fallback on the second DNS server if there is no response? Alternatively, is there any way I can tell different queries to go to different servers [maybe by setting up different subdomains; foo.local.something vs. bar.vpn.something]? Thanks

• IIS will not install on Windows 7 Pro 64 bit

  - by Paul

  I have a new PC running Windows 7 Professional 64 bit. I have an issue installing IIS - it goes through the install process, but at the end tells me "not all components could be installed", with no additional information given. There is no sign of an error in the install log or in event viewer. However, at this point, IIS is installed and working! I can run IIS manager, browse to localhost and see the default page, but at the next reboot the system rolls back and th einstall vanishes. I have tried installing II using the Windows Components section in Add/Remove Programs, I have also tried the Web Platform Installer and using the command line, all with the same end result.

• What is this jumper for on my new motherboard?

  - by jasondavis

  I am building a new PC, I just got my motherboard in the mail today. It is a ASRock X58 Extreme 3. I am reading over the manual for it and one of the jumpers says this. There is a 3 pin jumper labeled 1 2 3, with pins 1 and 2 shorted by default it is "+5v" If I manually change it to short jumper pins 2 and 3 instead of 1 and 2 then it will be "+5vSB (standby) for PS/2 or USB wake up events. So I am confused as to exactly what this is for. Can someone explain what it means, why I would want one other the other?

• How to monitor CPU usage and performance on a Hyper-V server with several VM's

  - by Bjørn

  Hello, I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system. I have set up three Virtual Machines, all running Windows 2008 32 bit. Build server, running Team City Staging server SQL Server, running SQL Server 2005 I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.) So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

• ESXi 4.1 CentOS 6.X eth0 unnavailable

  - by L.K.

  I don't usually ask for help so directly, usually google have all i need but this time i'm seriously lost. Hope you can help me .s The thing is, i have a server with Vmware ESXi 4.1 and 5 already running and configured virtual servers, but whenever i try to make a new one on CentOS 6.X it leaves me without eth0 to be activated in any way. When installing CentOS, in the screen of localhost.localdomain i try by the button in the left down corner of the screen to make eth0 connect automatically but it tells me a NetworkManager Error: cannot start eth0. So...in command line once the CentOS is already installed, i have configured ifcfg-eth0 and manually tried to take up the eth0 but when i restart network service "Bringing up eth0: Failed" and sometimes even "shutting down eth0: Failed" Thanks in advance

• Citrix XenServer iSCSI shared disk?

  - by chsguy

  I am running Citrix XenServer Essentials 5.5, with VMs stored on an EqualLogic iSCSI shelf, using XenServer's StorageLink. I would like to create a "virtual disk" that can be attached to multiple VMs. This would be used for a cluster file system like OCFS2 or GFS. This doesn't seem possible using the XenCenter GUI and I can't find anything online about how to do it. I realize I could simply expose the iSCSI network to the VM and have the VM initiate its own iSCSI, but that creates a lot of security challenges. This was pretty easy to do on Oracle VM Server, which is Xen based, so I know it's not a limitation of Xen itself. Maybe there is an "xe-" command for this? Thanks for any suggestions you can provide.

• Can't figure out how to make Slitaz USB persistent

  - by Dennis Hodapp

  I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent. One told me to add "slitaz home=usb" to the syslinux.cfg file like this: append initrd=/boot/rootfs.gz rw root=/dev/null vga=normal autologin slitaz home=usb but it didn't work for me. http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically. custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008) does anyone know the best way to make the USB automatically persistent?
