• Suspected network performance issue on VirtualBox Ubuntu guest on Win7 host

  - by Adam

  I set up Ubuntu 12.04 in VirtualBox on the Win7 machine I was allocated on my new project. I am running Java, Eclipse, Tomcat to develop a large data-intensive application and I noticed that this application runs at half the speed of my colleague's identical machine, where he runs it all under Windows. I think I have narrowed down the performance issue to the network, after comparing and equalising all the Java VM settings with my colleague. Is there a ping test I can do or some other network diagnostic test to flag up any problems? To give some background, the network performance is confusing. Running a network speed test to my colleague's machine with iperf shows speeds of 6 Mb/s from my Ubuntu guest, and 90 Mb/s from the win7 host. Large downloads, e.g. the Java SDK, come down at about 1.2 MB/s on both the guest and the host. Pings are sub-1ms on the host, but 1.5ms on the guest. I also did a broadband speed test, and got 10Mb/s download speed on both, but the host has an upload speed of 10Mb/s but the guest only uploads at 3Mb/s. I've been trying to diagnose any MTU problems with ping -M do to identify any kind of packet fragmentation problem but it's progressing very slow because I don't have much experience in this area. From what I read on other people's networking issues with VB and Linux guests on Win7 hosts, I should be able to get the speed on the guest up to the same level as the host. I installed a fresh VM with Ubuntu again to see if I'd foobar'd it somehow, but I'm getting the same readings with iperf on the virgin installation. My setup is: Adapter 1: Intel PRO/1000 MT Desktop (NAT) Adapter 2: ditto (host-only adapter) eth0 Link encap:Ethernet HWaddr 08:00:27:0b:76:bf inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe0b:76bf/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:86236 errors:0 dropped:0 overruns:0 frame:0 TX packets:49369 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:69163946 (69.1 MB) TX bytes:3530535 (3.5 MB) eth2 Link encap:Ethernet HWaddr 08:00:27:a3:26:b8 inet addr:192.168.56.101 Bcast:192.168.56.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fea3:26b8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:59 errors:0 dropped:0 overruns:0 frame:0 TX packets:57 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:9148 (9.1 KB) TX bytes:7648 (7.6 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:701 errors:0 dropped:0 overruns:0 frame:0 TX packets:701 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:66321 (66.3 KB) TX bytes:66321 (66.3 KB)

• USB Ports In Wrong Mode, How To Use usbmodeswitch?

  - by user86872

  I haven't had access to my USB ports as media devices for a couple days now. I've been reading and researching everything I can find but I can't find a good guide for usbmodeswtich or usbms that I can decipher. The USB's are fine for power, but won't support my android phone as a media device, which is killing me because I use adb everyday, and won't support my plug and play mouse any longer. Not sure what caused the switch, though I think it may be related to the suspend issue I've read about, but the solutions in those threads I read also didn't work. Below is my system information and details.

• Ping Unknown Host on CentOS at EC2

  - by organicveggie

  Weird problem. We have a collection of servers running CentOS 5 on EC2. The setup includes two DNS servers and two LDAP servers. DNS has a CNAME pointing at the primary LDAP server. One machine (and only one machine) is giving me problems. I can ssh into the server using LDAP authentication. But once I'm on the machine, ping won't resolve the LDAP host even though DNS seems to work fine. Here's ping: $ ping ldap.mycompany.ec2 ping: unknown host ldap.mycompany.ec2 Here's the output of dig: $ dig ldap.mycompany.ec2 ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> ldap.studyblue.ec2 ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2893 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;ldap.mycompany.ec2.

• Synergy and Screensaver Sync

  - by user10107

  Hi, I've been using Synergy for some time now to sync an Ubuntu machine and a Windows XP box, and it works really great. The one issue that still lingers is screensaver syncing. Meaning, that if, for example, the Linux box's screensaver is activate or deactivated, the Windows machine's screensaver follows suite. I've tried uninstalling the Gnome screen saver and also tried a different session altogether (e.g. xfce), but nothing seems to work. I've attached my configuration bellow. What else can I try? Thank you section: screens linux-box: windows-box: end section: links linux-box: left = windows-box windows-box: right = linux-box end section: options screenSaverSync = true end

• Methodologies for performance-testing a WAN link

  - by Chopper3

  We have a pair of new diversely-routed 1Gbps Ethernet links between locations about 200 miles apart. The 'client' is a new reasonably-powerful machine (HP DL380 G6, dual E56xx Xeons, 48GB DDR3, R1 pair of 300GB 10krpm SAS disks, W2K8R2-x64) and the 'server' is a decent enough machine too (HP BL460c G6, dual E55xx Xeons, 72GB, R1 pair of 146GB 10krpm SAS disks, dual-port Emulex 4Gbps FC HBA linked to dual Cisco MDS9509s then onto dedicated HP EVA 8400 with 128 x 450GB 15krpm FC disks, RHEL 5.3-x64). Using SFTP from the client we're only seeing about 40Kbps of throughput using large (2GB) files. We've performed server to 'other local server' tests and see around 500Mbps through the local switches (Cat 6509s), we're going to do the same on the client side but that's a day or so away. What other testing methods would you use to prove to the link providers that the problem is theirs?

• Staggering java linux process startup to prevent OOM

  - by ctennis

  I am running a number of java processes on a single Linux machine. From a memory and computing standpoint, everything is fine when things are static. However, periodically we use a configuration management package up upgrade the jar or war files, and restart the java process. The problem is, that is restarts them all relatively quickly, and so we get 10 or so java VMs restarting all at the same time (we use daemontools for the service stops/starts), which wreaks havoc on the machine, in terms of OOMs or just really slow. This is because it's spawning the JVM 10x at the same time. Other than trying to stagger the startups, is there a smarter way of handling this? Maybe a sysctl tuning performance parameters, or a JVM parameter?

• How can I reroute a sub-domain to localhost + port number?

  - by urig

  I have several web applications running on my developer machine. They mimic our production web applications which are hosted on sub-domain. For example, consider: api.myserver.com - is mimicked by 127.0.0.1:8000 www.myserver.com - is mimicked by 127.0.0.1:8008 and so on... How can I make it so that, on my Windows 7 machine, HTTP calls to "api.myserver.com" (note the lack of port number) are redirected to 127.0.0.1:8000 etc? Note that this needs to apply both to client-side calls (in the browser) and server-side calls (from IIS to Python development server and vice versa). Do I need a proxy to run locally to achieve this? Can you recommend such a tool?

• Website hosted on IIS is not accessbile

  - by Tola Odejayi

  I have two sites set up in IIS on a remote machine RM; one on regular port 80, and the other on port 5773. From my local machine LM, I can access the site on 80, but I cannot access the one on 5773; I get a status code of 502 and an error code of 10060 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) when I try to do this. I can access the 5773 site via IIS when I am logged into RM (i.e. by right clicking on a page on the site and going 'Browse'). I can also access pages on the 5773 site via a browser, again when I am logged into RM. I just can't do the same via a browser when I am logged into LM. I have ensured that port 5773 is open for outgoing traffic on LM. Could the problem be that I also need to ensure that port 5773 is open for inbound traffic on RM?

• Connecting to a LDAPS server

  - by Pavanred

  I am working on a development machine and I am trying to connect to my LDAP server. This is what I do - telnet ldaps- 686 then the response is - Could not open connection to the host on port 686 : connect failed But, the strange part is when I connect to my server - telnet ldap- 389 then the connection is successful. My question is, why does this happen? Do I have to install SSL certificate on the client machine where I make the call from? I do not know much about this. I know for a fact that the LDAP server is working fine because other applications are successfully using it currently.

• what does it mean for MalwareBytes to find malicious registry keys but nothing else?

  - by EndangeringSpecies

  I have a machine that is obviously infected, and when I ran MalwareBytes it told me that it found some "malicious" registry keys (surprisingly enough these contained file path to currently non-existent javascript files). But, that's it. Full scan did not uncover any malicious files, or malicious hidden processes in memory. Like, maybe the (hidden?) process that for whatever reason periodically injects keystrokes (hotkeys?) into whatever currently open window. Then on another, not obviously infected, machine it found a "malware.trace" registry key but again no files or processes etc. How does this jive with people's experience with MalwareBytes? Does it usually find registry key symptoms of an infection but nothing else? Or is it a common thing to have no infection but some malicious registry keys in place anyway?

• Remote Desktop fails with no error

  - by Duane

  Recently, I've been having problems connecting to a remote machine via RDP. I can connect fine exactly once, but all subsequent attempts fail until the remote machine is rebooted. I seem to authenticate properly, but the RDP logon dialog disappears after showing, "Configuring remote session..." for a few seconds. No errors or other useful info is written either to my screen or the Event Logs of the two machines involved. I've tried disabling remote sound as others have suggested, with no success. I'm still investigating a solution, but would appreciate any thoughts. Fortunately, I can reboot the box remotely w/o causing any problems, but this is a less than ideal workaround.

• How to set IP address of Amazon EC2 instance to its Elastic IP?

  - by TWord

  Hi, I have an Amazon EC2 instance running and I am installing a program on it that needs to know what the machine's IP address is. Can I set the Elastic IP address to the IP address within the EC2 instance? Its okay if it reroutes data packets somewhere 'outside' and then back to itself, but the software NEEDs me to specify an IP address of the machine its on. I proceeded with the software installation using the "local IP" (10.xx.xx.xx) within the software installation. I don't know if this is the reason why the application is not visible publicly (as I'm trying to determine in the question http://serverfault.com/questions/166946/allowing-web-access-to-an-amazon-ec2-windows-server-2008-instance-running-tomcat)

• 2.5" SSD in a 3.5" desktop drive bay normal?

  - by Cory Petosky

  I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor. Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!

• Shrink system volume, create new partition, & enlarge current partitions w/o losing data?

  - by studiohack

  My machine has a 300 GB hard drive. I'm planning to reinstall Windows 7 on this machine soon. It has three partitions: a System partition, and two equal data partitions for particular types of data (music, photos, docs, etc). These data partitions are too small for the data they hold, and the system partition is large enough to be shrunk. I want to create four partitions in preparation for the fresh reinstall, a System partition, and three data partitions of varying sizes (40, 50, & 60 GB respectively). My question: Can I shrink the System volume, create another partition, and make the existing two data partitions bigger without losing any data that is currently on the hard drive? Or is it better to format the whole thing, and create partitions after (thus removing the current OS) with a partitioning tool booting from CD? Can I reformat and create partitions with the Windows 7 set up DVD?

Currently I'm using VirtualBox to manage my virtual machines in my personal computer, but I'm moving my virtualization to a Server, so I set up a Linux server with KVM. And now I'm trying to import a virtualBox vm to KVM. So far I couldn't make it work. I already convert the ova file from VirtualBox to a format more familiar to KVM (qcow2), and I try to create a new virtual machine using virt-install command and setting the new virtual machine hard drive with the .qcow2 file. There is anyone could help me? thank you!

• IE9 development tools giving "Unable to attach to the process." error

  Notice: I have now rebuilt my machine to remove this bug, so I can no longer verify any answers. I recently installed Internet Explorer 9, and activated the development tools by pressing F12; I then clicked "script" and the "start debugging" button but I got the following error: Unable to attach to the process. Another debugger might be attached to the process. I get this message regardless of the site I am on (currently I'm on google.com). I have no other applications running, and have rebooted my machine. Can anyone suggest why this may be appearing?

• How to use graphical line drawing characters with Midnight Commander on OS X under ssh?

  - by Sorin Sbarnea

  I discovered that when I do ssh to a machine using OS X 10.6 and use mc I do not see the graphical line drawing characters. This does not happen if I open terminal and start mc. I'm connecting using putty configured to use xterm-color, configuraton that works just fine if I do ssh to a linux machine. The mc from OS X is version 4.7.0 (installed using macports). What locale returns: LC_CTYPE="C" <== ssh LC_CTYPE="UTF-8" <== Terminal.app ssh: mc display bits shows: 7-bit ASCII (changing does not help, it defaults to the same value) Terminal.app: mc display bits shows: UTF-8 The environment shows TERM=xterm-color in both cases Terminal.app and ss but mc looks different. I filed a bug to mc with this information at http://www.midnight-commander.org/ticket/2339

• nodejs server hanging from time to time

  - by Johann Philipp Strathausen

  I have a node server (0.6.6) running an Express application, along with Mongoose and s3, on an Ubuntu 11.04 machine. Several times per hour, the server is hanging. That means that the application is working fine, I see the express loggings, and then all of a sudden the server stops responding. No errors, no traces, no loggings, and strangely enough the browser won't show the request even in the network debugging window. From any machine in the local network it's the same behaviour. I restart the server and it's okay again for several minutes, then again starts to hang, everytime while doing something different. The same application on Amazon on the same Ubuntu version works fine and never hangs. I know all this is kind of vague, but I don't know where to start. Has any of you seen something like this before? Any idea?

• Windows 7: How to prevent Windows from caching my desktop wallpaper

  - by rmartz

  I have a service running that renders a changing wallpaper every 5 minutes or so, and replaces the current image file with the new one automatically (That is to say, new image but same filename). On Linux, the change is detected almost automatically, and so I have the most current wallpaper. However, on my Windows 7 machine (Which syncs the image with my Linux machine over Dropbox), it appears to cache the wallpaper from the last time I manually set the wallpaper. The image never changes, even if I restart. Is there a way to make Windows detect the file change, or periodically refresh the wallpaper cache? I'd like to avoid third-party apps if at all possible.

• What is the advantage of iSCSI over SMB?

  - by sofakng

  At my house I'm running a Hyper-V server with a Windows Server 2008 R2 VM acting as a file server. Files are shared across my network using SMB. (Also, the machine is using a PERC 6/i RAID card but I don't think that's important) I'm thinking about setting up a dedicated SAN (iSCSI) machine and then switching my Hyper-V server to ESXi. What are the advantages of using iSCSI versus SMB? I think I would still need a file server OS (eg. Win 2k8) sharing files via SMB so I'm not sure the end result would be any different than my current setup...

• Mutliple VMs for Tomcat cluster vs Multiple Tomcat instances on one physical box

  - by Greymeister

  I'm working on a project that will be implemented into production using a cluster of Apache Tomcat instances and I'm looking for the best Hardware/OS solutions and VMs have come up as one option. I have run ESXi/ESX instances before for development and testing, but I'm curious for a hosting environment if having multiple VMs is actually worse than just configuring a server to host multiple instances of Tomcat. These are my guesses: Pros for VMWare Easier Maintenance/Backup for individual VMs (VMWare makes this easy) Can remote login to individual VMs without having to give host access (security?) Easier way to re-purpose machine for OS/Hardware changes Pros for running on one Physical Machine Overhead of only one OS (also no VMWare footprint) Update OS/security changes once One less administrative layer (No VM expertise required) I'm curious if anyone has any other ideas about what the benefits would be for either option.
