  • How to securely enable file sharing over PPTP on Windows 2008 Server

    - by Damage
    I have set up a Windows SBS 2003 domain (LAN) and a stand-alone Windows 2008 Server (web server) at another location (workgroup). I established PPTP VPN connection (SBS dials web server) over which users from LAN should be able to access web server. On web server I enabled TCP/IPv4 and File and Printer sharing protocol. It has a few external addresses (one of them is default) AND one local address (192.x.x.x) assigned to network adapter. Firewall allows port 445 for file sharing. There's the problem - I can not enable web server file shares to be visible to LAN users and ONLY to LAN users: From SBS I can access webserver but I cannot access webserver from LAN workstations (XP, Vista). I have had same configuration - I have just replaced old (web server) Windows 2003 server with 2008 so SBS settings are the same (static route, DNS etc.). How can I enable file sharing on web server for LAN workstations? Now I have opened File and printer sharing to the internet which is of course totaly unsecure. I tried to secure the tunnel so I moved RAS (VPN) connection (Network Center) on web server to "Private" profile and moved firewall port 445 to "Private" profile but suddenly file sharing does not work and I cannot telnet webserver on port 445. How can I secure file sharing so I do not have to open it to the internet?

  • VPN IP Routing - slow connections

    - by dannymcc
    UPDATE: Router error logs show: LCP Time-out 0 I'm not sure how to correct this. The Lan-to-Lan profiles are set to -1 Idle Timeout (for the remote branch). I have a PPTP VPN running between two Draytek 2820 routers. They are setup that one dials out to the other one. Main Practice - 192.168.1.0/24 Branch - 192.168.3.0/24 I have then set (on the Branch) router the following route: 192.168.1.0/24 If I then request a server running on 192.168.1.1 from the Branch, it correctly routes through VPN tunnel. If I request the branch server at 192.168.3.1 it correctly routes to the local server without using the VPN tunnel. I have temporarily disabled the firewall on both routers, and made sure that QoS is disabled. The Main Practice internet connection is ~30mb down / ~10mb up, and the Branch connection is ~5mb down / ~2mb up. Anything over the VPN tunnel runs pretty slowly (VNC, Remote Desktop and Terminal Emulators). However, if I dial using the Windows VPN wizard, creating a connection from the laptop to the Main Practice - everything runs quickly. I'm looking for possible causes, and/or ways of further diagnosing the issue. Any help would be greatly appreciated! UPDATE: In summary, when I connect within the Branch and try and access a host that's within the Main Practice it works, but slowly. If I then dial the VPN on my Windows 7 laptop whilst still connected to the Branch network, it's fast. Main Practice Branch Practice Routing Table from Branch Router Key: C - connected, S - static, R - RIP, * - default, ~ - private * 0.0.0.0/ 0.0.0.0 via 126.256.126.103 WAN2 C~ 192.168.1.99/ 255.255.255.255 directly connected VPN-1 S~ 192.168.1.0/ 255.255.255.0 via 192.168.1.99 VPN-1 S~ 192.168.2.0/ 255.255.255.0 via 192.168.1.99 VPN-1 C~ 192.168.3.0/ 255.255.255.0 directly connected LAN2 C 126.256.126.103/ 255.255.255.224 directly connected WAN2 Routing Table from Main Practice Key: C - connected, S - static, R - RIP, * - default, ~ - private * 0.0.0.0/ 0.0.0.0 via 81.139.64.1, WAN2 S 81.137.176.1/ 255.255.255.255 via 81.137.176.1, WAN2 * 81.139.64.1/ 255.255.255.255 via 81.139.64.1, WAN2 C~ 192.168.1.204/ 255.255.255.255 is directly connected, VPN C~ 192.168.1.0/ 255.255.255.0 is directly connected, LAN S~ 192.168.2.0/ 255.255.255.0 via 192.168.1.204, VPN S~ 192.168.3.0/ 255.255.255.0 via 192.168.1.203, VPN Connection Details (from Branch Router) Connection Details (from Main Practice Router) IPERF.exe Output

  • big speed difference on a network link with and without VPN tunnel

    - by xirtyllo
    Scenario: We have a network link between two offices. The link is provided by a third party company through a VLAN on their network, but to us it is totally transparent -as if we had a simple ethernet cable going from one location to the other-. We have one router at each side of the link, with 3 VPN tunnels in between the two. The test: When I test the speed of the network link with the routers in place, with one laptop directly connected to the router on each side, I consistently get ~30/35Mbps. But if I take out the routers and I test the link connecting the laptops directly to the ethernet cable at each side, I consistently get ~85/88Mbps. It's quite a big performance hit, and I would tend to think that the VPN tunnels are responsible for the slow down. Is it normal that this configuration (two routers with three VPN tunnels between them) takes away so much bandwidth? More info: The encryption algorithm used for the VPN tunnels is AES128. The routers model is Zyxel USG200 and Zyxel USG1000, and their CPU, memory, and storage use is well within normal limits. The nominal bandwidth of the network link is 100Mbps. The network link in question is supplied by a third party company (the building in between our two offices). Basically it passes through their network as a VLAN, but the VLAN is completely transparent to us (e.g. no configuration required on our side, just like one single cable from end to end). Unfortunately (or maybe fortunately) I cannot directly test different routers configurations as I'm not the person in charge of it.

  • WGet or cURL: Mirror Site from http://site.com And No Internal Access

    - by alharaka
    I have tried wget -m wget -r and a whole bunch of variations. I am getting some of the images on http://site.com, one of the scripts, and none of the CSS, even with the fscking -p parameter. The only HTML page is index.html and there are several more referenced, so I am at a loss. curlmirror.pl on the cURL developers website does not seem to get the job done either. Is there something I am missing? I have tried different levels of recursion with only this URL, but I get the feeling I am missing something. Long story short, some school allows its students to submit web projects, but they want to know how they can collect everything for the instructor who will grade it, instead of him going to all the externally hsoted sites. UPDATE: I think I figured out the issue. I though the links to the other pages were in the index.html page that downloaded. I was way off. Turns out the footer of the page, which has all the navigation links, is handled by a JavaScript file Include.js, which reads JLSSiteMap.js and some other JS files to do page navigation and the like. As a result, wget does not pick up an other dependencies because a lot of this crap is handled not on web pages. How can I handle such a website? This is one of several problem cases. I assume little can be done if wget cannot parse JavaScript.

  • Software to clean up photos of whiteboards and documents?

    - by Norman Ramsey
    I take a lot of photos of whiteboards, blackboards, and so on for teaching purposes (examples online through May 2010). I'm interested in cleaning them up for archival purposes, preferably using Linux. Commercial products ClearBoard and PhotoNote are priced a little aggressively for my purposes, plus my students would like to have this capability too. Does anyone know of any good, open source software for Converting photographs to images with just a few colors? Eliminating perspective distortion? Removing unwanted junk from around the edges of an image? or anything like that? I'm imagining that I start out with a picture of my whiteboard using red and black markers, and I end up with a three-color image using just white, red, and black. Or I photograph a laser-printed document and end up with a clean black-and-white image. I have tried standard tools that reduce the number of colors in an image, and they do a terrible job—probably because they are trying to reproduce the uneven illumination of the original image. Command-line Linux tools would be ideal.

  • Cisco ASA 5505 (8.05): asymmetrical group-policy filter on an L2L IPSec tunnel

    - by gravyface
    I'm trying to find a way to setup a bi-directional L2L IPSec tunnel, but with differing group-policy filter ACLs for both sides. I have the following filter ACL setup, applied, and working on my tunnel-group: access-list ACME_FILTER extended permit tcp host 10.0.0.254 host 192.168.0.20 eq 22 access-list ACME_FILTER extended permit icmp host 10.0.0.254 host 192.168.0.20 According to the docs, VPN filters are bi-directional, you always specify the remote host first (10.0.0.254), followed by the local host and (optionally) port number, as per the documentation. However, I do not want the remote host to be able to access my local host's TCP port 22 (SSH) because there's no requirement to do so -- there's only a requirement for my host to access the remote host's SFTP server, not vice-versa. But since these filter ACLs are bidirectional, line 1 is also permitting the remote host to access my host's SSH Server. The documentation I'm reading doesn't seem to clear to me if this is possible; help/clarification much appreciated.

  • Advice on Auditing VPN Connections

    - by WhiteAdam
    I've inherited a network that is truly a mess and the VPN config is amazingly long with confusing group names and very little documentation. I am curious to see how others have gone about auditing these types of connections. Are there any forms out there? What information should I collect? I assume things like Customer, Department, Technical Lead, and etc. Thanks in advance for any advice on this nightmare.

  • How to protect web site against hackers?

    - by Adi barda
    Hi Guys, Like everyone of us, I have my own dreams about developing the next cool product that will be adopted by many users and become industry standard. Surprisingly, I find that the most challenging task is to keep my website up & running. My site is being hacked again and again no matter what I do - I blocked the FTP connections, changed the Joomla (CMS) database table names, installed all latest patches and what not. The web site supports the product (over 1800 users now...) by generating licenses, support forums, documentation, galleries etc. The product which is a winforms application cannot be marketed without this web site. My question: Do you have any innovative idea about securing joomla based web sites or what is the best secured web hosting you know. currently i'm hosting my site at ixwebhosting and i like them very much but obviously i can't do any serious marketing being hacked over and over again Thank you very much, Adi Barda

  • Feasible to use a laptop as a Digital Media Receiver/Extender?

    - by philosaur
    Since the price of many dedicated hardware Digital Media Extenders is only slightly lower than that of a cheap laptop, is there any reason you couldn't use a laptop as a Digital Media Extender? I'm looking for specific reasons that might make this unworkable. For instance, would the small screen/low-power video card of the laptop prevent the movie from playing well on the TV?

  • Site monitoring tool to look for javascript errors

    - by Agile Noob
    I am currently working on a site that includes javascript code that we get from several different sources and need to run on the site I maintain. Every once and a while some of this code breaks without our knowing until its too late. Is there a monitoring tool that will crawl our site and look for javascript errors and report them or could this be incorporated into a selenium test somehow?

  • App_Offline.htm, taking site down for maintenance

    - by Vipin
    There is much simpler and graceful way to shut down a site while doing upgrade to avoid the problem of people accessing site in the middle of a content update.   Basically, if you place file with name 'app_offline.htm' with below contents in the root of a web application directory, ASP.NET will shut-down the application,  and stop processing any new incoming requests for that application.  ASP.NET will also then respond to all requests for dynamic pages in the application by sending back the content of the app_offline.htm file (for example: you might want to have a “site under construction” or “down for maintenance” message).   Then after upgrade, just rename/delete app_offline.htm file…and the site would be back to normal. Just remember that the size of the file should be greater than 512 bytes, doesn't matter even if you add some comments to it to push the byte size as long as it's of the size greater than 512 - it'll work fine.     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html http://www.w3.org/1999/xhtml"http://www.w3.org/1999/xhtml" ><head>    <title>Maintenance Mode - Outage Message</title></head><body>    <h1>Maintenance Mode</h1>     <p>We're currently undergoing scheduled maintenance.

  • https:// search results appearing on Google for purely http:// site

    - by hydrurga
    I started weeding through my site's search results from Google today, using a site: search, to determine if there are any links that cause 404s and thus need redirecting. To my amazement I noticed numerous https:// results relating to various pages. My site doesn't have a SSL certificate, doesn't serve such pages, doesn't internally link to https:// pages, doesn't include any such files in its sitemap.xml and, for all of these, never has. I decided to do a Google search for https://<my site> and found one site that incorrectly refers to the root of my site with a https:// prefix - I will try to contact them to get them to correct this. I'm not sure however how Googlebot managed to index the non-root files as https://. I can't find any external links to them and surely, without certification, Googlebot should have stalled at the first request? I've just added the following lines to the site's .htaccess (although the surfer still has to navigate through the browser's "This site is a security risk. Abandon hope all ye who enter here!" message(s) first to get there): RewriteEngine On RewriteCond %{HTTPS} on RewriteRule ^(.*)$ http://www.<my site>.org/$1 [R=301,L] replacing <my site> with my domain name. My big question is this though - I would like to use the Google Webmaster Tools Remove URLs feature to remove the https:// pages from the index. Can I be guaranteed that this will only remove the https:// versions of each relevant page and not the valid http:// versions? My thanks to anyone who can help me out with this particular question and the issue in general.

  • Need help with ColdFusion and ASP.NET site [closed]

    - by Michael Stone
    To begin, I wasn't too sure how to title this.. I've got a few questions. First off, I've got a very big site that's in ColdFusion and we've been migrating to ASP.NET C# 4.0 the last 8 months. I've got a team of 7 programmers and no one can seem to figure out these answers, not even our senior C# programmer. We're using Team Foundation Server and we can't figure out how to only push up one small change at time. Right now we're stuck to publishing the entire site and it's causing serious issues. We've currently got the site as a Project and not a Website. We're wondering if that's one issue. I actually think it might be a problem. We're also dealing with an issue where we can't access our regular folders with relative paths. So we're first developing our admin side in .NET and We've got our regular site and then we've got another site within that for our .NET admin tools. By site, I'm referring to them actually being Sites in IIS. This also creates a problem for us when we're creating tools that upload images and want to store them and access them from our parent Site. I'd very much appreciate any advice on how to go about this in the most standardized way. So what I'm hoping for is advise on: -Publishing and managing a site/project in Team Foundation Server. Being able to push up one fix at a time if needed would be GREAT! -Any help figuring out the issuing referencing folders from my .NET child site to my parent ColdFusion site using regular relative paths. "/a/images/b/" would be nice nice instead of only being able to do "/b/images/" We're using ColdFusion 8, C# Asp.NET 4.0/Entity Framework/POCO Templates, and a Windows 2008 R2 Server. Thank you in advance for any help.

  • Google Analytics on Demo Site

    Will adding the UA code of the live site to a revision site affect anything adversely? They are, technically, two different sites with different metrics. I don't want to lose the old data when I initiate the new site, of course. I would also like to work on setting up the new analytics page while the revision site is in development. Does anyone have any good workflows on setting up a revision site without losing old site data?

Godaddy's staff said there is nothing they can do to prevent that site cloning the look and feel of my site. Is there anything I can do to stop another site from effectively cloning my site? How can I keep my customers from being duped by this?

    First of I'm very sorry but this questions is not so so specific. All I am looking for is a tutorial or a resource for creating a site-to-site VPN. Actually, I not even sure if that is what I should call it. I live in China and I want to access youtube and stuff. And I don't want to buy a proxy service so I'm trying to make my own VPN or proxy with Ruby on Rails. So again, my question is where is a resource for creating site-to-site VPN with Ruby on Rails.
