• Socksify TCP connections reaching a gateway IP -- preferably without iptables

  - by Alexandra Neagu

  I have Virtualbox installed on Debian with a few virtual machines. I can't install anything in the guests, and I use host only networking, vboxnet0. The host IP in the host network is 192.168.56.1, and the guests have static IPs in 192.168.56.0/24. I access Internet with a SOCKS proxy (without authentication) and I would like the Virtualbox guests TCP connections to be sent through the SOCKS proxy. This would also be useful for socksifying external TCP reaching a gateway network card or wireless access point. I looked at transocks, tun2socks, with dante-client, etc., but I don't know how can I achieve this without enabling IP forwarding in the host and using iptables. Maybe to attach somehow the Virtualbox vboxnet0 network to the tunnel tun0 used by tun2socks? Or maybe there is a way to do NAT to tun0 in Virtualbox? I only need TCP traffic and I don't need UDP, not even for DNS.

• Squid 3 reloading makes it stop serving requests

  - by coredump

  So, we use Squid 3 here (3.0.STABLE8-3+lenny4), pretty standard configuration (no dansguardian or similar) + NTLM authentication with LDAP background, circa 1000 users on a busy day, and our acls reference some external files (allowed/blocked sites/ip addresses). On Squid 2.X we used to be capable of reloading it's configuration (to add or sites or addresses to rules, etc) and squid would not stop serving during the reload. Since we changed to 3.0, that seems to be impossible: everytime we use reload (or -k reconfigure) it stop serving requests for as long as 2 minutes, and clients receive a Configured proxy is not accepting connections message. I checked the documentation and got nothing about it, does anyone else suffer from this problem or is it a isolated case on my setup? Also, if you have Squid 3.0 and doesn't suffer from this problem, how is your squid configured?

• Update twitter profile image using OAuth

  - by sjobe

  I'm trying to get twitter update_profile_image to work using OAuth. I was using curl with regular authentication and everything was working fine, but I switched to OAuth using this library, and now everything except update_profile_image works. I read something about twitter OAuth having problems with multipart data, but that was a while ago and the plugin is supposed to have dealt with that issue. My working regular authentication with curl code $url = 'http://api.twitter.com/1/account/update_profile_image.xml'; $uname = $_POST['username']; $pword = $_POST['password']; $img_path = 'xxx'; $userpwd = $uname . ':' . $pword; $img_post = array('image' => '@' . $img_path . ';type=image/jpeg', 'tile' => 'true'); $format = 'xml'; //alternative: json $message = 'Test update with a random num'.rand(); $opts = array(CURLOPT_URL => $url, CURLOPT_FOLLOWLOCATION => true, CURLOPT_RETURNTRANSFER => true, CURLOPT_HEADER => true, CURLOPT_POST => true, CURLOPT_POSTFIELDS => $img_post, CURLOPT_HTTPAUTH => CURLAUTH_ANY, CURLOPT_USERPWD => $userpwd, CURLOPT_HTTPHEADER => array('Expect:'), CURLINFO_HEADER_OUT => true); $ch = curl_init(); curl_setopt_array($ch, $opts); $response = curl_exec($ch); $err = curl_error($ch); $info = curl_getinfo($ch); curl_close($ch); My current OAuth code [I had to cut it down, so do not minor look for syntax errors] include 'EpiCurl.php'; include 'EpiOAuth.php'; include 'EpiTwitter.php'; include 'secret.php'; $twitterObj = new EpiTwitter($consumer_key, $consumer_secret); $twitterObj->setToken($_GET['oauth_token']); $token = $twitterObj->getAccessToken(); $twitterObj->setToken($token->oauth_token, $token->oauth_token_secret); try{ $img_path = 'xxx'; //$twitterObj->post_accountUpdate_profile_image(array('@image' => "@".$img_path)); $twitterObj->post('/account/update_profile_image.json', array('@image' => "@".$img_path)); $twitterObj->post_statusesUpdate(array('status' => 'This is my new status:'.rand())); //This works $twitterInfo= $twitterObj->get_accountVerify_credentials(); echo $twitterInfo->responseText; }catch(Exception $e){ echo $e->getMessage(); } I've been trying to figure this out for a while, ANY help would be greatly appreciated. I'm not in any way tied to this library, so feel free to recommend others.

• Should I install an AV product on my domain controller?

  - by mhud

  Should I run a server-specific antivirus, regular antivirus, or no antivirus at all on my servers, particularly my Domain Controllers? Here's some background about why I'm asking this question: I've never questioned that antivirus software should be running on all windows machines, period. Lately I've had some obscure Active Directory related issues that I have tracked down to antivirus software running on our domain controllers. The specific issue was that Symantec Endpoint Protection was running on all domain controllers. Occasionally, our Exchange server triggered a false-positive in Symantec's "Network Threat Protection" on each DC in sequence. After exhausting access to all DCs, Exchange began refusing requests, presumably because it could not communicate with any Global Catalog servers or perform any authentication. Outages would last about ten minutes at a time, and would occur once every few days. It took a long time to isolate the problem because it was not easily reproducible and generally investigation was done after the issue resolved itself.

• .htpasswd under IIS - does it work?

  - by Cyrcle

  I'm trying to password protect a directory on a server that's running IIS. I've put the following in the .htaccess file in that directory - AuthName "Restricted Area" AuthType Basic AuthUserFile /path/.htpasswd AuthGroupFile /dev/null require valid-user I've tried a whole bunch of different paths and although it's asking for a username and password it won't take it. I've tried using the path provided by _SERVER["PATH_TRANSLATED"] but that's no help either. Is this a problem with my path, or does IIS just not support .htpasswd?

• Decent simple SQL Server client

  - by John

  Hi, does anyone know of a very simple SQL Server client tool - that does the same basic functions as Management Studio (i.e. choose a database and run a query - doesn't need an Object Explorer, or anything fancy)? Ideally it would be great to have a single exe or zip file version that I could take around on a USB key - anything to avoid installing the full set of SQL Server client tools all the time! Thanks, John

• Widgets and .mobi sites, is this possible?

  - by Roland

  I have a couple of concerns, I'm busy building a normal .mobi site for a client, so basically how I understand this is keep it simply since most phones do not support JavaScript and have a small screen etc. So I build a mobi site using only content and basic links. Now my question is how do mobi widgets work on a mobile site? I've googled and could not find a answer? Is this possible at all?

• Is Session Replication ColdFusion 9 still not recomended?

  - by Tom Hubbard

  Is seems that Session Replication in ColdFusion servers less that 9 was considered not something to do on high scale apps. Instead the basic path would be to use round-robin and sticky sessions. Is this still the case for CF9 or has Session Replication been improved.

• IIS7 folder permissions

  - by Eanna

  I build a basic WCF service that I now want to host in IIS7 under Windows Server 2008 R2. I added the service as an application under the default web site but whenever i try to run the application I get the following error: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Config Error - Cannot read configuration file due to insufficient permissions The only way I can get this service working is if i choose to "connect as" the server Administrator when adding the service. the "application user (pass-through authentication)" option does not seem to work. Could anyone help me out, I've just started using IIS7 and have no idea what to do... Thanks

• Failed reverse DNS and SPF only when using Thunderbird!

  - by TruMan1

  I have a reverse DNS and SPF records correctly setup for my mail server. Sending webmail from it works perfect. The problem is when Thunderbird sends out emails, it is using the client's IP address for the hostname. I have SMTP authentication and specified my mail server's as the outgoing SMTP. Mail is being sent, but it is not "signing" the email with the mail server's IP address.. it is using the client's. Is there any way to fix this? This is the spam error I get when sending from Thunderbird: Spam: Reverse DNS Lookup, SPF_SoftFail

• CNTLM issue with intranet (maybe DNS)

  - by htorque

  On my Linux box I need to use an ISA proxy that requires authentication to reach the internet. I therefore installed CNTLM and configured it to point to the proxy address and listen on port 4321. I then configured my GNOME distribution to use localhost:4321 as global proxy for HTTP and HTTPS. The result: I can connect to the internet. I can ping intranet IPs, I do receive name resolution for intranet sites, yet I cannot ping them or open any intranet site in a browser (configured to use the distributions proxy) unless I use the site's IP address. I tried blocking the intranet IP range in the CNTLM config file without luck.

  - by z3a

  I'm trying to extend the basic user registration form and profile included in satchmo store, but I'm in problems with that.

Maybe some one can show me the correct way to do this?

• Using regexkitlite with strings containing % signs

  - by David Liu

  So I'm using RegexKitLite in my iPhone app, and I'm basically grabbing out a bunch of URLs and names from within a web page. The problem is that whenever it comes across a URL with URL encoded characters like %22 for a double quote or %27 for a single quote, the captured string basically gives me a jumbled overflowed string, containing garbage and even method names. I'm really not doing anything particularly special within the regex, just your basic "startdelimiter(.*)enddelimiter" regex.

• ReadyNAS issue with Google Apps?

  - by Jauder Ho

  The power went out (again) in my house today so I decided to set up some alerting. Since I have a ReadyNAS and the latest version of Raidinator seems to have SMTP TLS support, I figured I would try setting things up to email to a domain I have hosted on Google Apps. At this point, I have everything working IF I use a Gmail account but as soon as I switch to a Google Apps email address, it stops working and complains with smtpstatus=535 smtpmsg='535-5.7.1 Username and Password not accepted. Learn more at \n535 5.7.1 http://mail.google.com/support/bin/answer.py?answer=14257 30sm16076226wfd.23' errormsg='authentication failed (GNU SASL, method PLAIN)' exitcode=EX_NOPERM I'm wondering if anyone else has encountered this. Google's extremely aggressive captcha does not help but I am able to log in now without a captcha from a browser so I'm open to any ideas why the simple switch of a user/password combo that is supposed to work does not. I'm also attaching my config so that others can see how to set things up.

• SSH keys fail for one user

  - by Eli

  I just set up a new Debian server. I disabled root SSH and password auth, so you've gotta use a key file. For my primary user, everything works exactly as expected. I used ssh-keygen -t dsa and got myself a public and private key. Put one in authorized keys, put the other in a pem file locally. I wanted to create a user that I can deploy things with, so I did basically the same process. I addusered it, made a .ssh folder, ran ssh-keygen -t dsa (I also tried RSA), put the keys in their appropriate locations. No luck. I'm getting a Permission denied (publickey) error. When I use the exact same keys as the account that works, same error. When I enable password authentication, I can log in via SSH with the password. How do I debug this?

• Trouble with cross network permissions for an image through iis7 in an asp.net virtual directory

  - by EdenMachine

  I have load balanced web servers My web application has a function that allows the user to upload their company logo to display in the application header obviously, when they upload the logo image file, it needs to be in a central location or otherwise, the file will not be accessible to the other server on the load balancer. in order to be able to upload the image through the application other on one of either servers and then display it on both servers I need a virtual directory in IIS on both servers that point to a third "file server" (this is the "AcctData" directory shown below with a sub folder "images") the problem is that no matter what I do, I run into a permissioning issue If I use pass-through authentication I get a 401 error. If I use a specific user that's set up on both boxes, I get a 500 error. The "Default" application under "CP" (shown in the image below) uses an AppPool that is a Domain Account that has admin permissions on all the servers. I've also tried sticking a Web.config file in the "AcctData" directory allowing anonymous access. Nothing is working though.

• PHP: Proper way of using a PDO database connection in a class

I currently don't understand the basic of this (In GWT, i think it implement Comet), so is there anyone can give me a term or definition for this? so I can get it on Google for more information?

• Getting EOFException while trying to read from SSLSocket

  Hi, I am developing a SSL client that will do a simple request to a SSL server and wait for the response. The SSL handshake and the writing goes OK but I can't READ data from the socket.

Am I doing something wrong with the socket or with the SSL authentication? Thank you.
