• Monitor HTTP usage on network from Linux free

  - by David

  I manage a small office network. I am looking to start monitoring/logging internet usage (website requests) for each user on a small network. All the windows clients are running through a switch to a BT router. I also have a linux (centos) machine which is connected as a client to the BT router as well. Is there any free software I can install on the linux box (or my own machine) to allow me to log and monitor websites requested by users kind of like browser history. Ideally, something that would collect each client's browser history in 1 place. Thanks

• OpenVPN Push DNS Not Working Correctly On Windows

  - by woodsbw

  I currently have OpenVPN server setup on an Ubuntu machine, as well as DNSMasq. I am wanting to push DNS to the client (road warrior setup.) I had the push "dhcp-option DNS x.x.x.x" where x.x.x.x was an open OpenDNS server, for testing, and everything was working when I connected from my Windows client But now that I have DNSMasq setup, and I changed the "dhcp-option DNS x.x.x.x" to the DNSMasq server, but when they client connects it still receives the old, OpenDNS DNS server IP. I'm at a bit of a loss here, I have tried flushing DNS on the client, rebooting the server, and I even grep'd the entire server to see if the OpenDNS IP was in some other config I was missing...it wasn't. One other note, when connect to the VPN and explicitly run nslookup against against the DNSMasq IP, the addresses resolve correctly, so it isn't a DNSMasq issue.

• When trying to copy a virtual disk in VMware vSphere client, I get an errror.

  - by Zak

  I'm pretty new to all the VMware world, so this is probably mainly a question about the right set of documentation to look at. I'm trying to clone/copy a VM that I installed on an ESXi installation. I was trying to follow along with the top example here: http://serverfault.com/questions/16320/is-there-a-way-to-clone-an-existing-vm-on-an-esxi-server-without-having-to-re-imp However, I'm using the vSphere client to connect to the ESXi box and manage it, and the vSphere client is telling me it won't let me rename the vmdk file. The real answer I want is how do I clone the VM I installed if I want to spin up 5 copies. Is there another utility I can use to copy the vmdk file, then create a new virtual machine using it? Any idea why they nerfed the feature in vSphere client?

• How do I serve only internal intranet requests for a site with Apache?

  - by purpletonic

  I have an externally facing web server on our domain that we use for testing multiple sites. I have a site on this server that I want only people from within our intranet to view. How do I prevent requests originating from outside the intranet from seeing this website? I tried the following in my apache config file, but I get a 403 error. <Directory /> Options FollowSymLinks Order Deny,Allow Allow from domain.com Allow from 10.0.0.0/10.255.255.255 Deny from All AllowOverride None </Directory> <Directory /var/www/sitename/public> Options Indexes FollowSymLinks MultiViews Order Deny,Allow Allow from domain.com Allow from 10.0.0.0/10.255.255.255 Deny from All AllowOverride None </Directory>

• Should EC2 server self register or have admin server

  - by hortitude

  I'm creating AWS servers using chef. I am also planning on enabling auto-scaling. While we have automatic monitoring setup already (server density or nagios etc), I was also going to setup the cloud watch alarm for the status check on the server. This led me down the path of trying to decide whether to install the ec2-command-line tools on the server itself (which then requires me to install java on the servers -- despite no other need for Java in our environment) or to possible have an "admin" box that will check periodically for servers and make sure they have their alarms set. I expect this paradigm to carry over to other things we want to configure (perhaps ensuring that termination protection is setup on production servers?). Any thoughts as to why to go one direction or another?

• How to detect hard disk failure?

  - by Devator

  So, one of my servers has a hard disk failure. It's running software RAID, the system locked up and according to /proc/mdstat (and /var/log/messages), it's really down: Personalities : [raid1] md2 : active raid1 sdb2[1] 104320 blocks [2/1] [_U] md5 : active raid1 sdb5[1] 2104448 blocks [2/1] [_U] md6 : active raid1 sdb6[1] 830134656 blocks [2/1] [_U] md1 : active raid1 sdb1[1] 143363968 blocks [2/1] [_U] and Nov 5 22:04:37 m38501 smartd[4467]: Device: /dev/sda, not capable of SMART self-check However when I do smartctl -H /dev/sda, it passes the test. It also passes the test with smartctl --test=short /dev/sda. So, is smartctl a broken testing tool, or am I doing something completely off?

• Running Excel 2007 as admin on Win7 causes “There was a problem sending the command to the program”

  - by Flack

  I am running Excel 2007 on Windows 7 64bit. I need to run Excel as administrator so I have the "Run as Administrator" box in the Excel shortcut checked. Now, when I try to open an Excel file by double clicking, I get the following error: There was a problem sending the command to the program Excel opens fine after that, and I can open the file fine through Excel's File/Open menu. Why can't I open the file by double clicking? Some sites suggest changing a specific Excel option. I tried while checking/unchecking Excel's "Ignore other applications that use Dynamic Data Exchange (DDE)" but that didn't help. The issue goes away if I uncheck "Run as Administrator" but I want to be able to leave that checked. Any ideas?

• On boot firmware request for intel GMA 3100 chipset timing out

  - by Yannick M.

  I am currently in the process of installing a Gentoo linux box with a Vanilla 2.6.29-r5 kernel with gentoo-xen-kernel patches in order to run the Xen Hypervisor. After rebooting with the new kernel, the booting process seemed to hang on: [ 0.863005] platform microcode: firmware: requesting intel-ucode/06-0f-07 [ 60.863442] Microcode Update Driver: v2.00-xen <[email protected]>, Peter Oruba Apparently the firmware request times out after 60 seconds (/sys/class/firmware/timeout) and booting just continues. I have done some research and have found that on RHEL-4 this problem was related to the mount of /sys changed and the firmware.agent hotplug script couldn't parse the line correctly. However I am having some difficulty tracking down how to fix this on Gentoo. Any and all ideas are greatly appreciated! Thanks

• CentOS listen to everything on the wire

  - by Poni

  I know there's a native command on linux that will output (to stdout) every "event" related to a certain network interface (be it eth0 etc'). Like there's tail -f <file> to listen on file changes.. I just can't find it. I want to see all events, incoming packets, even dropped ones. At lowest level possible. In every protocol (TCP, UDP etc'). I think WireShark is a bit too big for this as I need something very simple just to see the events, it's for testing. What's the command?

• Why does NetworkManager take so long to connect to the wireless network?

  - by spoulson

  I have a Dell Mini9 that came with Ubuntu 8.10. Out of the box, Wifi configuration was done under System settings - Network and worked straightforward. Then, after some update patches, NetworkManager was installed to replace this functionality. Initially, it did not carry over my settings and I had to figure out how to redo it. After lots of bumbling with it, it finally works. However, after bootup the NetworkManager icon waits about 2 minutes before even attempting to connect to the wireless network. Then, about a minute later, it connects and I'm on my way. The Mini9 boots up within 30 seconds from SSD, so opening Firefox and then waiting 3+ min for wireless networking is a bit of a pain. Can anything be done?

• Keyboard Navigation of File Open Dialog in Windows 7

  - by dkusleika

  In Windows XP standard File - Open dialog, the top has a "Look In" box. I can press Alt+I to drop down a tree of the disks folders and easily navigate to other folders or network shares. In Windows 7, I can't seem to navigate the File - Open dialog as easily. The best I've been able to muster is to tab 5 times (in Excel 2007, but I assume it's a windows standard), then use arrow keys or use Alt+arrow keys like a browser to get around. It's simply not as good because I can't see the whole tree at once. Is there a way to see the whole folder tree? If not, do you have any other tips for keyboard navigation of the file open dialog in Windows 7?

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks

• download speed is fast but transfer rate is slow

  - by Ieyasu Sawada

  I've just changed ISP and I'm pretty disappointed with the transfer rate. My previous connection has a download speed of 1.08 Mb/s as seen from this site: http://speedtest.net and the download transfer rate is about 100kb/s for sites that doesn't limit their bandwidth. Now my connection has about 2Mb/s download speed but the transfer rate is dancing from 20-50kb/s . I was expecting a speed much higher than this because of the download speed that I'm getting when I'm testing. The question is what's the difference between transfer rate and download speed, is it normal to have a high download speed but low transfer rate, should the download speed be proportional to the transfer rate?

• AutoHotKey - change mouse position and click a specific key every time window comes up

  - by John

  I'm a newbie to AHK, learning the basics. I'm using Notepad as an example - I want to hit the Cancel key every time I close Notepad and it asks if I want to Save/Don't Save/Cancel. I've come up with the script below and it works once but then I have to reload the script to do it again. I want it to hit Cancel every time the question box comes up. I thought Loop would work but am doing something wrong. Any ideas why, anyone? Loop IfWinExist Notepad, { WinWait Notepad WinActivate Click 312, 109 return }

• How should I remotely manage Dell Poweredge 2850 running Ubuntu server?

  - by Saul

  First I've got to say I'm a Linux / Ubuntu novice, so go gentle on me as I'm on day 3. I've managed to get Ubuntu server Ubuntu 8.04 LTS installed and running on the Poweredge 1850 I bought off ebay. The box will go in a rack at my office but I want to be able to work on it and power on and off from home and I gather that (maybe) IPMI over LAN might be the way to do this, or maybe its something to do with BMC or something? I want to be able to administer/manage from a client PC at home running XP. I will be configuring the office router to port forward port 80 and 443 to the Ubuntu server running Apache2, and I'm puzzled about how the remote management works (unless it comes on a different port forwarded to a different internal IP) Thanks for any help

• Reduce the I/O priority of Windows Backup (Windows Server 2008 R2)

  - by HelloSam

  I have a PostgreSQL running on Windows Server 2008 R2 x64 box. And I have scheduled a backup everyday from the RAID 1 DB disk to a dedicated standalone disk. They are SAS 15k on Dell PERC 6i. I am using the built-in Windows Server Backup for purpose. The problem is, whenever the backup process is kicked in, the database performance is hogged. I would say almost a 10x of performance reduction. From the resource monitor, the disk queue is in the double digit range when backing up, and less than 1 during the day. The disk activity is like ~30-50MB/s during backup, so I guess the hardware is acting normally, though wbengine.exe takes up most of the portions. I think reduce the IO priority of the backup process would be an answer, but I couldn't find a way to. Tuning process CPU priority does not seems to help.

• Git Daemon on linux?

  - by bwawok

  Trying to set up a simple git-daemon on a linux server, and talk to it from a windows box. On linux server: Make a folder /home/foo/bar CD to /home/foo/bar do a git --bare init here Do a touch git-daemon-export-ok CD to /home/foo Run the command git-daemon --verbose --reuseaddr --base-path=/home/foo --enable=receive-pack On Windows Client w tortoise Git Do git.exe clone --progress -v "git://servername/bar" "C:\source\myFolderName" (works) Create file a.txt, add it to git, and commit (works) Do a git.exe pull "origin" master and then get fatal: Couldn't find remote ref master (makes sense, master isn't there yet) Do a git.exe push "origin" master:master and tortoise hangs forever without do anything I realize why I can't pull from master yet on the remote branch.. but why can't I push my first commit into the remote repo? #4 really should work. Tried it both with tortoise and the mysysgit command line, both cases I hang forever. What am I missing? Server has no useful log

• Why is my FTP output file blank?

  - by Nathan Long

  From the Windows command prompt, I have FTPd to a Windows web server. I can get a file, and I can see a directory listing with dir, but I want to save that list locally. I tried dir > c:\somefile.txt, and the file is created, but it's blank. Same thing if I do ls > c:\somefile.txt. The result is the same when I FTP from a Linux box. FTP sends back the following: 200 PORT command successful 150 Opening ASCII mode data connection for /bin/ls 226 Transfer complete

• UPS recommendations for three grey boxes?

  - by Margaret

  Hey all We have a series of grey-box style computers acting as servers at my workplace (rather than rack-mount). We were looking to get Uninterruptible Power Supplies for them. However, I'm not sure how many at what capacity are required. I'd assume it would be a good idea to hook the peripherals in as well - there's a 18.5" LCD monitor with a KVM, along with a couple of USB hard drives that require power. I currently have the most vital machine hooked up to a cheap (temporary) UPS, but it's probably close to worse than nothing. I'm looking for reasonable value for money, though I can probably negotiate with my boss on price range. I recognise that I may well need to buy two (or even three) UPSs to support the three machines. Any recommendations?

• Dell Vostro 1000 w/fresh XP Pro installation running very slow

  - by Ssvarc

  I'm working on a Dell Vostro 1000 laptop. It was running slowly and hanging, antivirus scans turned up nothing and the same with the Dell diagnostics (DFT hung - but Dell's diagnostics gave the HD a pass) so I imaged the HD and installed XP Pro on it. The laptop is still slow! (It takes a noticeable delay to enter words into the Google search box in IE and the computer hangs every time it enters the XP screensaver.) What are the likely possibilities at this point and how would I go about checking for them?

• How to recover Virtual Machines in Virtualbox?

  - by Bruce Connor

  For some reason, all of a sudden, all virtual machines are gone from the User Interface in virtual box. I suspect CCleaner has something to do with it, but that's not the point. Both the virtual hardisks and the .xml files for the machines are still in their respective folders. How can I use them to get my virtual machines back into virtualbox? I tried simply creating a new machine from the old virtual hardisks, and it worked with the ubuntu guest, but not with the windows one. Plus, it'd be nice to get my old machines back instead of having to create new ones, that would keep me from having to fix some shortcuts as well as reconfigure shared folders and other stuff. Thanks EDIT:Running Windows. [Solved]

• Internal USB A Female to motherboard 4-pin that mounts internally

  - by rockinthesixstring

  I'm wondering if anyone knows of a product like this but that is physically mountable internally rather than on a cable? I'm planning on building a super low profile "gateway" pc that is dedicated to handling internet traffic in my home. I have a great 1U rackmountable chassis for an ITX motherboard, but I need the hard drive real estate for the additional NIC required to run a gateway (one onboard and one PCI). So the plan is to use a small 8GB USB Jump Drive for the OS inside the box (as to not have one hanging out the back. And although it's racked, I still don't want the jump drive flopping around internally, so I want it fixed somehow. I have an alternative idea where by I use a flush mount zap strap saddle and a zip tie to hold it in place, but that seems kind of like a hack.

• Linux router and firewall with IP accounting

  - by Andrew

  I'm working on a project to replace my organisation's aging Slackware gateway/router/firewall machine in our colo rack. Previously we used rc.firewall but we are now looking for something more modern and easily configurable. The requirements are: Act as a gateway router & firewall Port forwarding to a Terminal Server in the colo IP/traffic accounting, preferably accessible via SNMP (already using cacti for other servers) Possibility of acting as a PPTP server & routing these connections Is not an out-of-the-box Cisco product (don't have the finances or support to maintain it) I'd prefer to use Ubuntu or some other Debian-based distro but something that integrates everything we're looking for is certainly an option if it offers all the desired features and is easy to configure. Is there a simple set of packages that will provide me with the Firewall & Accounting features, or am I best served with a custom-built distro / other solution?
