  • How do I bridge a connection from Wi-Fi to TAP on Mac OS X? (for the emulator QEMU)

    - by penx
    I'm trying to setup a bridge between my Wi-Fi connection and an emulator (QEMU). I need a virtual machine to be on the same LAN as the host, with its own IP address. QEMU requires using a TAP (virtual network device) so I have installed tuntaposx, have it running, and can open up QEMU using a TAP: qemu-system-arm -kernel zImage.integrator -initrd arm_root.img -m 256 -net nic -net tap,ifname=tap1 -nographic -append "console=ttyAMA0" I have a script that configures the bridge once QEMU has opened up the TAP interface: sysctl -w net.link.ether.inet.proxyall=1 sysctl -w net.inet.ip.forwarding=1 sysctl -w net.inet.ip.fw.enable=1 ifconfig bridge0 create ifconfig bridge0 addm en1 ifconfig tap1 0.0.0.0 up ifconfig bridge0 addm tap1 ifconfig bridge0 up If I manually set an IP on the VM, I can ping from the VM to the host, but not from the host to the VM. Also, I can't access the rest of the network from the VM - including not being able to set an IP over DHCP. Any ideas?

  • Why does the Internet WI-FI connection of my laptop disconnect when I connect the ethernet cable to the LAN?

    - by Joey Hammer
    Why does the Internet WI-FI connection of my laptop disconnect when I connect the ethernet cable to the LAN? These are two separate networks, the LAN is without Internet, I just use it to connect the tablet to the laptop and smart phone in my home network. The WI-FI is owned by the landlady and connects to the Internet. I know it should be possible to be connected both to the Internet through WI-FI and to my other computers and gadgets through the LAN because sometimes it works, but sometimes when I connect the ethernet cable the WI-FI disconnects and I wonder why? Pongy OS: Windows 7

  • Is it possible to detect that a database connection is to a copy rather than to the original database?

    - by user149238
    I have an application that needs to know if it is connected to the original database that it was installed with or if the connection is to a copy of that database. Is there any known method to know if the database has been cloned and the application is no longer connected to the original? I am specifically interested in MS SQL Server and Oracle. I was kicking ideas around for a stored procedure but that most likely doesn't have access to the hardware to confirm unique hardware information that would somewhat guarantee that the database is the one that it was originally connected to during installation. I'm trying to prevent/detect cloning of a database so that there is only 1 "true location of truth". Thanks!

  • What can I do to configure my SSH such that it pauses for a flaky connection?

    - by kfmfe04
    I run ssh from OSX to a Ubuntu box - under home WIFI, everything works perfectly. However, when I ssh from certain external networks, ssh may be working fine for a minute or two and then drop due to a flaky network (diagnosed by pinging 8.8.8.8). How can I set up ssh so that it simply waits/pauses rather than drop (when dropping, I have to setup my development environment from scratch - a big hassle). EDIT When I say a bad connection, I mean, for example, ping 8.8.8.8 will work fine for a while, and then fail for 40-50 pings, and then come back on again.

  • Frequent connection drops when playing online games (StarCraft 2, Battlefield 3) and behind NAT - how to diagnose?

    - by Moshev
    I am having some trouble with (I suspect) my wireless router. It's connected to the internet with a regular lan cable and has a static, public IP address. Our two home PCs connect to the router with regular lan cables, plus there's a laptop which connects over wifi. diagram: Internet | | <- isp-supplied cat5 ethernet cable | D-Link D300 ...wifi... laptop / \ / <- cable -> \ PC1 PC2 The PCs and laptop are behind NAT and share the router's public IP. The router is a D-Link D300. PC1 is used for online gaming and I'm experiencing frequent "connection dropped" errors when playing Battlefield 3, StarCraft 2 and the Diablo 3 beta; but not with TeamFortress 2 or the Tribes Ascend beta. The issue goes away when I remove the router and connect PC1 directly to the ISP's cable. I have also tried disconnecting PC2 and the laptop, leaving PC1 as the only machine connected to the router - doesn't help. How can I diagnose what precisely the issue is?

  • What antivirus software supports updates without an internet connection?

    - by Michael Gundlach
    I'm putting antivirus software on Windows 7 computers in the middle of Africa. The computers don't have internet access, but still need to be protected against viruses from CDs and thumbdrives. Separate from these computers is one computer that does have extremely spotty internet access. What's the best AV software for this situation? The important part, as I see it, is that we need to keep the computers up to date, but can't let the AV software suck down updates at its leisure: the computers are disconnected, and getting emails onto the connected computer is a challenge enough. We thought we might transfer update files to the connected computer using a protocol that can handle repeated connection drops (e.g. FTP with resume.) Then we'd manually apply the update files to the disconnected computers. Does any AV software support this? Is there a better solution?

  • Connection between Windows Web Server in DMZ and Windows Application Server and MS SQL Database Server within LAN [closed]

    - by user1345260
    Excuse me for being naive. But I'm a newbie. We have a Windows Web Server within DMZ and a Windows Application Server and MS SQL Database Server. What ports do we open for connection between them? For example: Someone opens the Data Driven Website on the Web Server and they should be able see the data that the website is trying to access from the Database. Currently, I'm planning to open the following ports on the Web Server to establish the access, 80 HTTP 443 HTTPS 21 FTP 3389 RDP 53 DNS 1433 MS SQL Server Please validate my assumption. I would highly appreciate your help. Also, please provide me any articles on this topic so that I can read.

  • Why does my ethernet connection keep re-connecting, only with Windows?

    - by Nick Bolton
    I'm using Windows 7, and I have several computers on my network. For some reason, the network connection keeps disconnecting and immediately re-connecting. Infact, it may just be refreshing the DHCP lease... but I'm not sure. I've tried changing the network card, and ethernet cable, but the issue is still happening. I can only imagine that the issue is with the ethernet switch, but this doesn't happen on my other desktop which uses the same ethernet switch. Any ideas?

  • How do I automatically download files to a Kindle 2 whenever its USB connection is plugged into a Windows 7 machine?

    - by Bob Cross
    The inspiration of this question is the Gadget Lab article How To Make Your Kindle Into an Automatic Instapaper. In that article, they describe an implementation of an Automator workflow that: Detects the connection of a portable disk (which the workflow assumes is the Kindle 2). Downloads the Instapaper mobi file containing the text version of the articles marked for "Read Later" to the computer. Downloads the mobi file from the computer to the Kindle 2. All of this is straightforward in terms of functionality but it is not immediately obvious how to do step 1 on a Windows box. Is the Task Scheduler the first step? If so, which event should be the trigger for the rest of the task?

  • How to get stable WIFI connection between phone and router when thousands of irrelevant phones are around?

    - by Karl
    I want to use Android phones to check tickets at the gate of an event. These phones are connected to a password protected router (WPA2) and a PC to validate. That all works nicely in a test setting, but I'm worried it might collaps if there are many other competing phones around. How can I get a stable WIFI connection between my phones and my router when thousands of irrelevant phones are around? Do the other phones clogg the router with requests even when the router is password protected? Shall I hide the SSID?

  • How can I use my Windows 7 computer to share WiFi connection with PCs that don't have wireless?

    - by Tom Auger
    Long story short: modem and wireless router are downstairs and we're having a LAN party where some visitors don't have wireless. There's no way to run the length of cabling required, so looking for options. My Windows 7 Home Premium PC has a wireless-n connection, and I'd like to see if I can use it as a "hub" or switch of sorts, running an ethernet cable out of the back and into a switch, then splitting off to the other PCs. Is this an option? I know with Internet sharing, you can set up your PC as a wireless access point, but I want to do the opposite.

  • WIFI connection interfering with Windows Server 2003 Active Directory domain. (How to debug?)

    - by Vinko Vrsalovic
    RELATED: This question has led me to ask this one. I had to change our unnamed crappy ADSL router to a crappy Comtrend CT-5361 WiFi router, now every WiFi connection to the domain doesn't work correctly: Joining the domain is impossible (see related question) Logging into the domain takes ages Authentication usually fails Question: How to debug this and pinpoint the exact problem? I have no enough knowledge on either WiFi networks or on Active Directory to know which connections are made at which stages nor how to check what's happening at the wireless level to compare what should happen to what is happening. I'm looking for resources to learn what should be happening and tools to detect what is actually happening (I expect a sniffer should be enough, but if there are better, more specialized tools, that'd be great).

  • How can I limit the amount of messages SendMail will recieve in a single incoming connection?

    - by Mike B
    Is there a way to limit how many messages can be received by SendMail in a given SMTP session? I have a SendMail server and an upstream application server is trying to send dozens (potentially hundreds) of messages to it in a single SMTP session (ehlo... mail from... rcpt to... data... rset... mail from... etc). This is causing resource strain on the box since the traffic isn't effectively load balanced. I'd like to implement a policy to have sendmail only allow up to X number of messages in a given SMTP session after which it will require the remote host to reconnect again. I noticed that there's a confCONNECTION_RATE_THROTTLE option but that seems to protect more against multiple connections occurring at once - not a single connection sending a bunch of emails.

  • SSAS processing error: Client unable to establish connection; 08001; Encryption not supported on the client.; 08001

    - by Kevin Shyr
    After getting the cube to successfully deploy and process on Friday, I was baffled on Monday that the newly added dimension caused the cube processing to break.  I then followed the first instinct, discarded all my changes to reverted back to the version on Friday, and had no luck.  The error message (attached below) did not help as I was looking for some kind of SQL service error.  After examining the windows server log and the SQL server log, I just couldn't see anything wrong with it.After swearing for some time, and with the help of going off and working on something else for a while.  I came back to the solution and looked at the data source.  Even though I know I have never changed the provider (the default setup gave me SQL native client), I decided to change it and give OLE DB a try.This simple change allows my cube to process successfully again.  While I don't understand why the same settings that worked last week doesn't work this week, I don't have all the information to say with certainty that nothing has changed in the environment (firewall changes, server updates, etc.).SSAS processing error:<Batch >  <Parallel>    <Process xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ddl2="http://schemas.microsoft.com/analysisservices/2003/engine/2" xmlns:ddl2_2="http://schemas.microsoft.com/analysisservices/2003/engine/2/2" xmlns:ddl100_100="http://schemas.microsoft.com/analysisservices/2008/engine/100/100" xmlns:ddl200="http://schemas.microsoft.com/analysisservices/2010/engine/200" xmlns:ddl200_200="http://schemas.microsoft.com/analysisservices/2010/engine/200/200">      <Object>        <DatabaseID>DWH Sales Facts</DatabaseID>        <CubeID>DWH Sales Facts</CubeID>      </Object>      <Type>ProcessFull</Type>      <WriteBackTableCreation>UseExisting</WriteBackTableCreation>    </Process>  </Parallel></Batch>                Processing Dimension 'Date' completed.                                Errors and Warnings from Response                OLE DB error: OLE DB or ODBC error: A network-related or instance-specific error has occurred while establishing a connection to SQL Server.

  • Is there anyway to make a Rails / Rack application tell the web server to drop the connection

    - by dasil003
    There are many security reasons why one would want to drop an HTTP connection with no response (eg. OWASP's SSL best practices). When these can be detected at the server level then it's no big deal. However, what if you can only detect this condition at the application level? Does Rails, or more generally Rack, have any standard way of telling the server to drop the connection without a response? If not, are there some standard headers to pass in that will accomplish that in common web servers (I'm thinking Nginx or Apache)? Even if there is not a standard header is there a reasonable way to configure that behavior? Is this a fool's errand?

  • How to add an Interbase connection pool to glassfish?

    - by kgrad
    Hi, I am attempting to add an Interbase connection pool to GlassFish v3 to use EJB 3.1 in a project. The glassfish log appears to be connecting to my database properly, it spits out all my table names and indices. However, I get an error INFO: fetching database metadata SEVERE: could not complete schema update java.lang.NullPointerException at interbase.interclient.ResultSet.local_Close(Unknown Source) ... And when I ping the connection pool from within Glassfish I receive "Ping failed Exception - null". I have the following properties set with my connectionpool: resource type: javax.sql.DataSource Datasource Classname: interbase.interclient.DataSource portNumber: 3050 as well as my database info. I can't seem to find information elsewhere. This question is similar but did not receive an answer. thanks.

  • Data Access Layer in ASP.Net: Where do I create the Connection?

    - by atticae
    If I want to create a 3-Layer ASP.Net application (Presentation Layer, Business Layer, Data Access Layer), where is the best place to create the Connection objects? So far I used a helper class in my Presentation Layer to create an IDbCommand from the ConnectionString in the web.config on each page and passed it on to the DAL classes/methods. Now I am not so sure, if this part shouldn't also be included in the DAL somehow, because it obviously is part of the Data Access. The DAL is in a separately compilated project, so I dont have access to the web.config and cannot access the connection string (right?). What is the best practice here?

  • Is re-using a Command and Connection object in ado.net a legitimate way of reducing new object creat

    - by Neil Trodden
    The current way our application is written, involves creating a new connection and command object in every method that access our sqlite db. Considering we need it to run on a WM5 device, that is leading to hideous performance. Our plan is to use just one connection object per-thread but it's also occurred to us to use one global command object per-thread too. The benefit of this is it reduces the overhead on the garbage collector created by instantiating objects all over the place. I can't find any advice against doing this but wondered if anyone can answer definitively if this is a good or bad thing to do, and why?

  • How to Grab MAC Address of Active Ethernet Connection in Bash Script?

    - by Huy Tran
    Simple Question: How do I grab the MAC address of the active Ethernet connection in a bash script? I currently have: set - `/sbin/ifconfig eth0 | head -1` MAC=$5 Which outputs the MAC address of the eth0, but if it's eth1 that's active, I want that instead. Could I beforehand execute ifconfig | grep inet but that wouldn't tell me which interface is active, just that one is active. I need to grab the line above it to tell me which one is the active connection. Any help would be much appreciated. Thank you!

  • How to complete a git clone for a big project on an unstable connection?

    - by LaPingvino
    I am trying to git clone the LibreOffice codebase, but at the moment I have an internet connection by mobile phone of about 300kbps and it's just anything but stable. I can get the connection back any moment, but then the git clone process already stopped working, and no way to get it running again. Is there some way to have a more failure-resistant git clone download? One option I considered myself is to download someone else's .git directory, but that is overly dependent of others and doesn't seem like the best possible solution to me.
