• Using m0n0wall in a VM for testing.

  - by tombull89

  I'd like to use m0n0wall inside a (VirtualBox) VM to play about with and see what it can do. Ultimately the goal is to have a number of virtual machines connected to a internal virtual network which goes through to the m0n0wall VM, and then the m0n0wall box connected to the internet through NAT or a bridged addaptor on my host machine. I can find out how to set the LAN and WAN addresses, but this seems to be only for using m0n0wall as a router intead of attached to another router. Let's see if I can diagram this: [Virtual Machine]---Internal (VM Only) Network ---[m0n0wall VM]---Bridged/NAT Addaptor---["real" router]---Internet. Can anybody suggest how I should do this or am I thinking m0n0wall isn't meant to be used like this?

• Finding day of week in batch file? (Windows Server 2008)

  - by Daniel Magliola

  I have a process I run from a batch file, and i only want to run it on a certain day of the week. Is it possible to get the day of week? All the example I found, somehow rely on "date /t" to return "Friday, 12/11/2009", however, in my machine, "date /t" returns "12/11/2009". No weekday there. I've already checked the "regional settings" for my machine, and the long date format does include the weekday. The short date format doesn't, but i'd really rather not change that, since it'll affect a bunch of stuff I do. Any ideas here? Thanks! Daniel

• Good SEO - Why is Good SEO Better Than Its Evil 'Black Hat' Brother?

  With the rise of today's technology, a number of bad and dodgy practices have come into play that can seriously put your website at risk from being banned in the search engines - no questions asked. The constant shift of techniques and 'state of flux' the search engines remain in makes it difficult to differentiate between good and bad SEO.

• Permission denied when trying to execute a binary burned to a CD-R

  - by user16654

  On an Ubuntu 9.10 (Karmic Koala) machine, I burned a CD from the command prompt using: cdrecord -v speed=16 dev=0,1,0 /FPS.iso The CD now contains an executable and some files. I tested the CD by loading it onto another machine (Red Hat 5.3) and when I try to run the program I get the following message: bash: ./FPS1_1: Permission denied I can open other files like text documents (the executable also comes with shared libraries). I realized I had burned the CD as root so I burned another one as another user but I still have the same problem. How can I remove this permission or what is the problem? P.S. the image was in / if that helps

• Recovering database files from a corrupted VHD

  - by Apocalypse9

  We have a SQL server hosted on a virtual machine. Our hosting company updated/restarted the server and for some reason the virtual machines became unbootable. We've spoken to Microsoft and used a few higher level tools to attempt to recover the virtual machines but were unsuccessful. In browsing the file system the database folder doesn't even appear. I'm wondering if there are any lower level tools that might be able to find and copy the database files. As far as I know the physical hard drive is ok, so I'm hoping there may be some way to recover the files themselves even if the rest of the virtual machine file-system is a loss. Obviously we're in a bit of a bind, and any help/ suggestions are very much appreciated.

• Dell Inspiron 1501 battery no longer "recognized"

  - by mwalling

  My parents were on vacation last weekend and franticly called me saying that they couldn't get their Inspiron 1501 to boot anymore without the BIOS whining about the battery. Before this happened, they said the "battery went dead with negligible pre-warning". On bootup, the computer says: WARNING: The battery cannot be identified. This system will be unable to charge this battery. With options to enter the BIOS or continue booting. I got to look at the machine last night. The battery still holds a charge, and will recharge. Windows detects it as a DellPY9617 battery manufactured by "DynaPack". I didn't get the BIOS revision, but the machine's ship date was 7/21/2007. The recommendations I could find on the internet varied from "discharge the battery completely" to "your computer is too old" to "update the BIOS", and wanted a more specific answer before doing something drastic.

• Network Path not found while joining Active Directory

  - by Chiggins

  So I have an Amazon EC2 box running Windows Server 2008 with Active Directory installed on it. I also have a Windows 7 virtual machine, which is set to use the Active Directory box as its DNS and WINS server. I'm trying to join the virtual machine to the domain, and I'm asked for authentication. I give authentication, wait a minute, and I get an error saying: The following error occurred attempting to join the domain "ad.chigs.me": The network path was not found. How can I fix this so that I'll be able to join the domain? Thanks!

• Duplicate Name Exists error from virtual PC with NAT network configuration

  - by Phred

  Whenever I change the network configuration to NAT for a virtual machine running under Virtual PC 2007, I get "A duplicate name exists on the network." error. There is no other machine on my network with this name and running the VM in any other network configuration doesn't cause this error. This seems to be a common problem with Virtual PC 2007 based on a google search but no-one seems to have a solution to it. So far, I've discovered that turning off NETBIOS over TCP causes the problem to go away but I need to join this VM to a domain and you can't do that if NETBIOS over TCP is turned off.

• what is the meaning of *this* crontab setting?

  - by aXqd

  * */1 * * * sh foo.sh I found this setting on one production machine. And foo.sh was executed every one minute. I am guessing that the original author of this setting wants it to be executed every one hour. And I cannot find the official meaning of this setting in the crontab man page. Hence please help. UPDATE: I extracted these logs from that machine, however I cannot find the law out of them. 2013-06-29 20:47:01 2013-06-29 20:50:02 2013-06-29 20:51:01 2013-06-29 20:53:01 2013-06-29 20:54:01 2013-06-29 20:57:01 2013-06-29 20:58:01 2013-06-29 21:00:01 2013-06-29 21:05:02 2013-06-29 21:10:02

• Centrally manage Windows 7 computers without Active Directory

  - by Sean W.

  I manage three Windows PCs at home using the principle of least privilege. This means that practically every other day when a new version of Java is released, I have to manually install the update using my administrative credentials on each machine. This is starting to become more work than I had expected. I would love to set up an active directory domain at home, but Microsoft has discontinued Windows home server; its replacement, Windows server 2012 essentials is much more expensive (about $500). Are there any free (preferably as in speech) that would allow me to centrally manage the software installed on each machine in a manner similar to that of active directory? I'd also like to find a way to centrally manage security settings, but I doubt there's an equivalent of group policy. Samba 4 would be an ideal solution, but according to its own developers, it is not yet stable enough for production use.

• using wbadmin to backup and recover

  - by g7rpo

  HI I am using wbadmin to perform backups of a specific folder, primarily to backup my VHD files this is working fine but I tried to recover the files today using a different machine to the one which created the backup and couldnt get the machine doing the recovery to 'see' the backups. Is there a way to do this as my worry is that if I have a failure on the host which is perfmorming the backups I need to be able to install hyper-v on another host and recover the backed up VMs to there until I can rebuild the host. It appears that this isnt possible, I am hoping I am missing something. Any help would be greatly appreciated.

• Is it common in companies that non-techs are doing analyzes

  - by Kubi

  It's been 2 months since I started working at an international big consulting company. I like my colleagues personally but it's like a joke since my first day. Analysts (people who has no idea about the tech. background) are planning the workflow and functions. In my case, none of my friends here even wrote even a single line of html. When I say Html, I doubt if they know what I mean. But they are deciding about really key decisions in a web system implementation project. Is this always like this?

• iptables: separate clients from each other

  - by Florian Lagg

  Hello, is there a way to separate clients in a subnet so that they cannot reach each other? The infrastructure currently looks like this: 192.168.0.1/24 Gateway, a CentOS box with iptables. 192.168.0.10-20 Some clients which may reach each other 192.168.0.30 A single client which should not be able to reach the hosts 192.168.0.10-20 should be able to reach the gateway and the internet I don't know if it is possible, maybe you could give me your ideas how it could be done. I cannot influence the machine 192.168.0.30 because it is a virtual machine I want to rent to someone. Thanks.

• Cannot flush the DNS on Snow Leopard 10.6.8

  - by Andy Woggle

  I have an absolutely bizarre problem and it has STUMPED me.. I cannot seem to flush the DNS on my Snow Leopard 10.6.8. I have tried sudo dscacheutil -flushcache , i've tried dscacheutil -flushcache and it hasn't worked. I'm building a website, and changed the directories yesterday. Now when I check it on my other machine, it works fine. When I get somewhere from distance to check, it works fine, but it's seemingly stuck in the DNS on this machine as the CSS is not showing. Is there a hard-flush method (if that makes sense)? The two above did not work.

• WSUS moved how to reset the database and check the folders?

  - by Matthew Zielonka.co.uk

  I have a bit of a problem with a WSUS box, I backed up the WsusContent folder (about 180 gig) to a second machine, wiped the first machine then realized I don't have the database folder! I can not find any articles / guidance on this, I have re installed WSUS however it does not find the other files which where previsously downloaded (I guess the database being the reason). If I do a reset it will force it to download the ones it has again I guess and does not check what is still to be downloaded? Sigh... love / hate WSUS at the moment with a passion :) Thanks for any help.

• Is there a suitable chain for iptables when eth is in Promisc mode?

  - by user1495181

  I have a fron-end machine. Machine have2 eth cards. I want to use netfilter queue to do some checks on the packets. I set eth like this: ifconfig eth0 0.0.0.0 promisc up ifconfig eth1 0.0.0.0 promisc up I want to have an iptable rule like this(only example): iptables -A INPUT -i eth0 -j LOG --log-prefix " eth0 packet " but the packet is no passed through the iptables ,because it dosnt target to this MAC. Promisc mode didnt help. I saw that there is a way to add iptables chain for PROMISC, but need compilation... Is there any simplier way to have iptables rule when packet is not target to this eth. Currently i bypass this by creating a bridge between 2 eth and put rule on the FORWARD, but i done want to create bridge.

• Getting started with VNC

  - by Stephen

  I have subscribed to a VPS service for the purpose of running some remote applications. To do this I'm going to need a remote desktop of one sort or another. With this in mind it was suggested that I try Ubuntu. The installation that was prepared for me was Ubuntu 11.10 64 bit (Ubuntu 11.10 (GNU/Linux 2.6.18-348.4.1.el5.028stab107.1 x86_64)) From here I used apt-get install ubuntu-desktop which completed successfully. I rebooted the machine and reconnected via ssh. When I attempt to connect from TightVNC on my Windows machine I get a message about the session being actively refused. What should I do to confirm the service is running? Do I need to setup a firewall rule to allow the ports to pass through? (I am a linux newb so explicitness is appreciated)

• iTunes Home Sharing with VPN

  - by Philip Crumpton

  I'm trying to set up a VPN on a Windows machine that contains my iTunes library, then connect my iPhone ot it, wirelessly, using Home Sharing (remotly). I have read that this can easily be set up if the iTunes library is on a Mac (Network Beacon and YazSoft ShareTool are two products I found). I can't find anyone who has had success on a Windows machine, though. In my thinking, there are a few options to getting this done. Find a utility that takes care of this for me (like the Mac-only options listed above) and is compatible with iPhone (Hamachi is NOT compatible with iPhone VPN). Manually configure a VPN to allow Bonjour multicast (I'm not sure what this really is...) Emulate a Mac on my Windows PC. FYI my router is a Linksys WRT54GL running Tomato 1.28 Note question is related to this

• What are some ways of making manageable complex AI?

  - by Tetrad

  In the past I've used simple systems like finite state machines (FSMs) or hierarchical FSMs to control AI behavior. For any complex system, this pattern falls apart very quickly. I've heard about behavior trees and it seems like that's the next obvious step, but haven't seen a working implementation or really tried going down that route yet. Are there any other patterns to making manageable yet complex AI behaviors?

• Mapped network drive missing from My Computer and Explorer

  - by matt wilkie

  On a Windows XP Pro SP3 machine one network drive refuses to show up in My Computer or Explorer. The missing drive letter is G:, if that matters. Other mappings work fine. Other profiles one the same machine have no problem seeing G:. I can access the G: just fine typing it into the address bar or in CMD shell. I've used TweakUI to toggle hide/show G: with no difference. TweakUI says G: should be visible. I've logged off,on between toggles to make sure the settings are taking effect. I've looked at reg key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and made sure it's zero'd.ref We've limped along with this broken setup for some time, just working around it, but some applications do not allow typing in a path when choosing a place to save files and it's reached the point where it's intolerable. So, anyone have any idea why XP won't show this drive letter? or how to fix it?

• UTF-8 locale portability (and ssh)

  - by kine

  I spend a lot of my time sshed into various machines, all of which are different (some are embedded, some run Linux, some run BSD, &c.). On my own local machines, however, i use OS X, which of course has a userland based on FreeBSD. My locale on those machines is set to en_GB.UTF-8, which is one of the available options: % echo `sw_vers` ProductName: Mac OS X ProductVersion: 10.8.2 BuildVersion: 12C60 % locale -a | grep -i 'en_gb.utf' en_GB.UTF-8 Several of the more-capable Linux systems i use appear to have an equivalent option, but i note that on Linux the name is slightly different: % lsb_release -d Description: Debian GNU/Linux 6.0.3 (squeeze) % locale -a | grep -i 'en_gb.utf' en_GB.utf8 This makes me wonder: When i ssh into a Linux machine from my Mac, and it forwards all of my LC_* variables with that 'UTF-8' suffix, does that Linux machine even understand what is being asked of it? Or is it just falling back to some other locale? In either case, what is the mechanism behind its behaviour, and is it dependent on any particular set-up (e.g., will i see the same behaviour on a BusyBox-based system as on a GNU-based one)?

• Mark packets across computers?

  - by eudemo

  I use Transmission on Ubuntu and I'm having this issue, which basically says that QoS is broken because there is no way to limit which outgoing ports uses. I was thinking of doing a dirty and ugly hack and create an interface alias and define QoS based on source address, but was wondering if is there another way. Is it possible to mark the packets on the original machine in some way, using the owner and mark modules of iptables and sending this to the router who does the QoS? From what I understand, mark on iptables only applies to the local machine, so this will not work, but is there another way?

• Client PC not booting when certain TFT plugged in - TFT or graphics card failure?

  - by Chake

  here comes something quite strange: On a client machine (DELL Vostro 420) we experienced problems when booting: when turning on the machine beeps normal but doesn't display anything and doesn't boot. After some testing I found out, that this only happens if one (of the two) monitors (Iiyama ProLite E2472HDD) is plugged in while booting. If the other monitor (TFT 2) is plugged in everything is fine. Here a small illustration, TFT 1 is the bad guy: TFT 1 | TFT 2 | failure x | x | x x | | x | x | After BIOS-Phase I can safely plug in TFT 1 and everything works just fine. The question is, what can be done to avoide this behavior: Change monitor? (Iiyama ProLite E2472HDD) Change graphics card? (GeForce 9800 GT) Other suggestions?

• can't run binaries or shell scripts

  - by hyperboreean

  I am running Debian testing and I am not able to run any binary or shell script. I keep getting "No such file or directory". The umask is the default one and I haven't fooled around with the paths. Also, I am aware of this question, but it doesn't work out for me - I compiled my code on this machine and trying to run it on the same machine. Also, all of my shell scripts have the correct shebang. Any advices?
