  • How to set up a wireless AP with a linux box and SOCKS proxy

    - by user50455
    I've got: (1) Linux box (Arch linux to be precise, but that doesn't really matter) (2) Ethernet connection on it (say, eth0) (3) Socks proxy on a remote site (say, remote :port), which can be accessed through (2) (4) Wireless card on local linux box (say, eth1) So, the task is: create a wireless access point using (4) on local site (1) in such a way that all connections from it will go through proxy (3). E.g., when one simply connects to that AP (well, there should be DHCP or something for that) and goes to serverfault.com, all the traffic goes through that SOCKS proxy. I'm just asking for the digging direction and some references, not step-by-step tutorial. Thanks in advance

  • DFS-R (2008 and R2) 2 node server cluster, all file writes end in conflictAndDeleted

    - by Andrew Gauger
    Both servers in a 2 server cluster are reporting event 4412 20,000 times per day. If I sit in the conflictAndDetected folder I can observe files appearing and disappearing. Users report that their files saved by peers at the same location are overriding each other. The configuration began with a single server, then DFS-R was set up using the 2008 R2 wizard that set up the share on the second server. DFSN was set up independently. Windows users have drives mapped using domain based namespace (\domain.com\share). Mac users are pointed directly to the new server share created by DFS-R. It is PC users indicating most of the lost files, but there has been 2 reports by Mac users about files reverting.

  • Ubuntu Laptop as a wireless hotspot on bridge mode

    - by nixnotwin
    I have a wired router to which my ubuntu laptop connects via ethernet. The wierless NIC of the laptop acts as a wireless hotspot on master mode. I use hostapd fo this. I have bridged eth0 and wlan0, so my wireless clients that connect to my laptop over wifi get ip from the wired router via dhcp, so the devices get registered at the wired router ( and the laptop is just an access point). I use the following commands to get my laptop+accesspoint working: sudo brctl addbr br0 sudo brctl addif br0 eth0 sudo hostapd /etc/hostapd/hostapd.conf & sudo dhclient -d br0 & sudo ifconfig wlan0 192.168.1.15 netmask 255.255.255.0 up sudo brctl addif br0 wlan0 These commands enable me to access internet on my wireless clients and also on the laptop which is acting as wireless accesspoint. But if I reboot the wired router (without rebooting the laptop that is acting as accesspoint), Internet access on the laptop+accesspoint gets lost, but on wireless clients it works fine. Even I have not been able to figure out a command which will reset the laptop interfaces to default settings, so everytime the router reboots, I have to reboot the laptop too to get into default settings so that I can re-enter the above mentioned commands. My first question is How can I have my bridge+accesspoint up and running even-though the router reboots? And is there a command to set the interfaces to a default state? (ifdown -a doesn't work, after issuing the command the bridge still remained).

  • finding the best network latency between two countries

    - by Yoav Aner
    I know there are many tools to test for bandwidth and latency, but they all rely on having at least one host from which you can run those tests. I wonder whether there's an online source or some other way to guestimate the latency or speed between two countries (in general). For example, would a customer in Japan get lower latency if the server is located in Singapore or Australia? Is a user in India likely to get higher download speed from a server in the UK or in the US? Are there any online resources or some clever ways to answer those questions with a reasonable degree of accuracy? [UPDATE]: Thanks for the great suggestions from Raffael Luthiger. I didn't know about those looking glass servers. The submarine cable maps were also really cool to discover (Thanks to Jesper Mortensen). Also seems really wise if I could ask those network professional in the area for their experience, but obviously I don't have access to those. At least some of them are on SF :) However, I'm still a little unsure how to combine those resources to give me some measurements. This is the information I have: Two countries (A,B). I do have IP addresses of customers in country A (I can obtain those from the web server log files for example). Presumably I can find some looking glass servers in country B and run a trace to those IPs. What's the best measurements to use? Are there any scripts that help automate at least some of this process?

  • Network Load Balancing, intermittent port problem on Windows Server 2008

    - by Jimmy Chandra
    Trying to troubleshoot an intermittent problem on a Windows Server 2008 NLB. I think it might be related to an NLB issue. We are using Windows Network Load Balancing to balance load for our multiserver SharePoint front ends. Say... Web Front End 1 IP is 192.168.1.100 and Web Front End 2 IP is 192.168.1.101, the NLB is setup to load balance both WFE servers on any incoming traffic to the IP 192.168.1.200. Sometimes we got an intermittent issue where when we try to access the SharePoint site using 192.168.1.200:8080 (say the site is set up to run on port 8080) from a remote client, it will display page not found. Pinging the 192.168.1.200 will give responses, but when trying to telnet to 192.168.1.200:8080 it just won't connect. However, browsing the SharePoint site directly on individual WFE (192.168.1.100 and 192.168.1.101) show no problem whatsoever. My guess also (we didn't get a chance to try it yet, but I think it should work), if I try connecting remotely to individual server, it will respond just fine. But any attempt on trying to connect using the virtual IP (192.168.1.200) will fail miserably. Funny thing is, after a while it will return back to normal. Anyone had similar experience with this type of problem while implementing NLB before? We are doing this in a virtual environment.

  • Windows Media Center HDMI Capture Cards

    - by RSolberg
    I'm working on a new software application that utilizes windows media center to play recorded TV shows in the center of the screen. We can get this to work with standard coax or RCA input TV Tuner/Capture cards. My question is this... Are there any TV tuner / capture cards out there that allow you to use Windows Media Center with an HDMI input of some kind?

  • How passively monitor for tcp packet loss? (Linux)

    - by nonot1
    How can I passively monitor the packet loss on TCP connections to/from my machine? Basically, I'd like a tool that sits in the background and watches TCP ack/nak/re-transmits to generate a report on which peer IP addresses "seem" to be experiencing heavy loss. Most questions like this that I find of SF suggest using tools like iperf. But, I need to monitor connections to/from a real application on my machine. Is this data just sitting there in the Linux TCP stack?

  • Temp files created in every folder in Windows Server 2003

    - by i.h4d35
    So we have some folders which are shared over the AD Domain (Windows Server 2003). It was just noticed that in 2 of those folders (which contain only Excel and Word files), whenever a file is opened and closed, the temp file which was opened corresponding to that file still remains. Apparently, this's been going on for the past couple of years (which has led to an insane amount of temp files in each folder/subfolder under those shared folders). These shared folders are under the D:drive and not C: drive. There is only one group (containing 2 users) who access the said folders. I cannot understand if this has to do with the settings/permissions for the User/Group/Individual Client machine. For now, I have manually deleted all the temp files from each folder/subfolder. While this is not critical at the moment, I'd still like to clear this up. Also, it takes an additional fraction of a second to open folders that contains more than 10,000 temp files. Thanks in advance.

  • Roughly cutting Fibre Cables

    - by Bryan
    I recently asked a question about which type of Fibre optic cable to use for my installation. We have now found a cable type and supplier and I'm about to order the cable (OM3, Tight Buffered, 12 Core), however I have a further question: We are shortly moving in to a new building (still being constructed) and we are about to get a window in which we will be able to run any cabling that we need. How should I roughly cut the fibre? Can I just use some heavy shears to cut through the cable? I'm aware that doing so will damage the ends, but will the damage be limited to the ends, or could the cracks/fractures continue up the length of the cable? p.s. I have already allowed for several metres of extra cable at each end, and I am going to get a specialist in to terminate the fibres.

  • Using local proxy to specify used NIC on Windows 7?

    - by Nico
    I'm running Windows 7 and have 2 NIC installed, both are connected to the Internet (nic#1 LTE, nic#2 DSL). Windows 7 will only allow me to specify a binding order and a metric on which interface to chose but i can't specify this on an application level. My Idea was to use a local proxy server and use the proxy server whenever i want to use nic#2. I tried wingate and free proxy, both applications will let me chose the interface i want to use but this setting seems to have no effect? This is how i configured the applications: http://imageshack.us/photo/my-images/69/freeproxysettings.jpg/ http://imageshack.us/photo/my-images/811/wingateproxysettings.jpg/ Is what i'm trying to do in anyway possible?

  • Samba 'include' a per user config script

    - by cb0
    It is possible to use the include = /somepath/%u.smb.conf in the global section to call a script /somepath/cb0.smb.conf if the user cb0 connects to the samba server. Unfortunately this does not wotk for me because testparm alway gives me Can't find include file /somepath/.smb.conf When I connect to the server I can enter a username and pass but it alway rejects the connection. I'm using Samba Version 3.2.5 How can I achieve to load a custom user script depending on the user that is connecting ?

  • AFP / Apple Filling Protocol aka Netatalk access over Internet

    - by PJJ
    I got a simple cloud server and thought it would be nice to have mac native afp Volumes accesss. Installed Netatalk and this seems to work pretty nice. No sensitive data or something but I don't like to wake up someday and have my www docs rm-rfed by some kid h4x0r. Q1: Is afp encrypted? Q2: How can I make it (semi)secure? Q3: Does VPN makes sense for this? Q4: What would you do to get afp working over net? Opening any service meant for Lan only is a basic flaw, i know - but me be ignorant about it. According to Apple Dev only the authentication is encrypted or am I mssing something?

  • How can I enable anonymous access to a Samba share under ADS security mode?

    - by hemp
    I'm trying to enable anonymous access to a single service in my Samba config. Authorized user access is working perfectly, but when I attempt a no-password connection, I get this message: Anonymous login successful Domain=[...] OS=[Unix] Server=[Samba 3.3.8-0.51.el5] tree connect failed: NT_STATUS_LOGON_FAILURE The message log shows this error: ... smbd[21262]: [2010/05/24 21:26:39, 0] smbd/service.c:make_connection_snum(1004) ... smbd[21262]: Can't become connected user!

Should it not be trying to "become guest user"?

  • Write permission when mounting Windows shares from Ubuntu

    - by Ola Tuvesson
    I think I'm close to having my dev environment set up exactly the way I want, but one final snag remains. I'm running VirtualBox on a Windows 7 64bit host, with my dev enviroment inside a Ubuntu 12.04 guest. I want to keep the files for my projects on the host filesystem - partly so I can access them when the Ubuntu guest is not running, but also so I can use Tortoise and other Windows based tools (cough Photoshop), and it also eases my backup scheme somewhat. So I've got a folder "Rails" on my NTFS drive, which I've shared from the host with a user specifically created for the Ubuntu guest. The mount point has been set up and an entry added to fstab (cifs), using a credentials file and the options iocharset=utf8,file_mode=0777,dir_mode=07??77 This mounts fine and my Ubuntu user has both read and write permissions to the contents, but when I try to start my Rails app I get permission errors on any files the app needs to write to (e.g. the log file). What gives?

  • Test site speed

    - by Elad Lachmi
    I am test driving an Akmai CDN architecture and before committing to buy, I would like to gauge the real performance gain from the acceleration feature. What would be the best MO for doing speed tests from different locations around the world? I would like to test the page load speed and not just the server response time. I would like to test speed from as many edge locations as possible. I do not mind a paid service as well, if it is optimal. Thank you!
