• Is there a tool that can test what SSL/TLS cipher suites a particular website offers?

  - by Jeremy Powell

  Is there a tool that can test what SSL/TLS cipher suites a particular website offers? I've tried openssl, but if you examine the output: $ echo -n | openssl s_client -connect www.google.com:443 CONNECTED(00000003) depth=1 /C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA verify error:num=20:unable to get local issuer certificate verify return:0 --- Certificate chain 0 s:/C=US/ST=California/L=Mountain View/O=Google Inc/CN=www.google.com i:/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA 1 s:/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA i:/C=US/O=VeriSign, Inc./OU=Class 3 Public Primary Certification Authority --- Server certificate -----BEGIN CERTIFICATE----- MIIDITCCAoqgAwIBAgIQL9+89q6RUm0PmqPfQDQ+mjANBgkqhkiG9w0BAQUFADBM MQswCQYDVQQGEwJaQTElMCMGA1UEChMcVGhhd3RlIENvbnN1bHRpbmcgKFB0eSkg THRkLjEWMBQGA1UEAxMNVGhhd3RlIFNHQyBDQTAeFw0wOTEyMTgwMDAwMDBaFw0x MTEyMTgyMzU5NTlaMGgxCzAJBgNVBAYTAlVTMRMwEQYDVQQIEwpDYWxpZm9ybmlh MRYwFAYDVQQHFA1Nb3VudGFpbiBWaWV3MRMwEQYDVQQKFApHb29nbGUgSW5jMRcw FQYDVQQDFA53d3cuZ29vZ2xlLmNvbTCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkC gYEA6PmGD5D6htffvXImttdEAoN4c9kCKO+IRTn7EOh8rqk41XXGOOsKFQebg+jN gtXj9xVoRaELGYW84u+E593y17iYwqG7tcFR39SDAqc9BkJb4SLD3muFXxzW2k6L 05vuuWciKh0R73mkszeK9P4Y/bz5RiNQl/Os/CRGK1w7t0UCAwEAAaOB5zCB5DAM BgNVHRMBAf8EAjAAMDYGA1UdHwQvMC0wK6ApoCeGJWh0dHA6Ly9jcmwudGhhd3Rl LmNvbS9UaGF3dGVTR0NDQS5jcmwwKAYDVR0lBCEwHwYIKwYBBQUHAwEGCCsGAQUF BwMCBglghkgBhvhCBAEwcgYIKwYBBQUHAQEEZjBkMCIGCCsGAQUFBzABhhZodHRw Oi8vb2NzcC50aGF3dGUuY29tMD4GCCsGAQUFBzAChjJodHRwOi8vd3d3LnRoYXd0 ZS5jb20vcmVwb3NpdG9yeS9UaGF3dGVfU0dDX0NBLmNydDANBgkqhkiG9w0BAQUF AAOBgQCfQ89bxFApsb/isJr/aiEdLRLDLE5a+RLizrmCUi3nHX4adpaQedEkUjh5 u2ONgJd8IyAPkU0Wueru9G2Jysa9zCRo1kNbzipYvzwY4OA8Ys+WAi0oR1A04Se6 z5nRUP8pJcA2NhUzUnC+MY+f6H/nEQyNv4SgQhqAibAxWEEHXw== -----END CERTIFICATE----- subject=/C=US/ST=California/L=Mountain View/O=Google Inc/CN=www.google.com issuer=/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA --- No client certificate CA names sent --- SSL handshake has read 1777 bytes and written 316 bytes --- New, TLSv1/SSLv3, Cipher is AES256-SHA Server public key is 1024 bit Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : AES256-SHA Session-ID: 748E2B5FEFF9EA065DA2F04A06FBF456502F3E64DF1B4FF054F54817C473270C Session-ID-ctx: Master-Key: C4284AE7D76421F782A822B3780FA9677A726A25E1258160CA30D346D65C5F4049DA3D10A41F3FA4816DD9606197FAE5 Key-Arg : None Start Time: 1266259321 Timeout : 300 (sec) Verify return code: 20 (unable to get local issuer certificate) --- it just shows that the cipher suite is something with AES256-SHA. I know I could grep through the hex dump of the conversation, but I was hoping for something a little more elegant. I would prefer Linux tools, but Windows (or other) would be fine. This question is motivated by the security testing I do for PCI and general penetration testing. Update: GregS points out below that the SSL server picks from the cipher suites of the client. So it seems I would need to test all cipher suites one at a time. I think I can hack something together, but is there a tool that does particularly this?

• Need help merging 2 AHK scripts

• Why does setting a geometry shader cause my sprites to vanish?

  - by ChaosDev

  My application has multiple screens with different tasks. Once I set a geometry shader to the device context for my custom terrain, it works and I get the desired results. But then when I get back to the main menu, all sprites and text disappear. These sprites don't dissappear when I use pixel and vertex shaders. The sprites are being drawn through D3D11, of course, with specified view and projection matrices as well an input layout, vertex, and pixel shader. I'm trying DeviceContext->ClearState() but it does not help. Any ideas? void gGeometry::DrawIndexedWithCustomEffect(gVertexShader*vs,gPixelShader* ps,gGeometryShader* gs=nullptr) { unsigned int offset = 0; auto context = mp_D3D->mp_Context; //set topology context->IASetPrimitiveTopology(m_Topology); //set input layout context->IASetInputLayout(mp_inputLayout); //set vertex and index buffers context->IASetVertexBuffers(0,1,&mp_VertexBuffer->mp_Buffer,&m_VertexStride,&offset); context->IASetIndexBuffer(mp_IndexBuffer->mp_Buffer,mp_IndexBuffer->m_DXGIFormat,0); //send constant buffers to shaders context->VSSetConstantBuffers(0,vs->m_CBufferCount,vs->m_CRawBuffers.data()); context->PSSetConstantBuffers(0,ps->m_CBufferCount,ps->m_CRawBuffers.data()); if(gs!=nullptr) { context->GSSetConstantBuffers(0,gs->m_CBufferCount,gs->m_CRawBuffers.data()); context->GSSetShader(gs->mp_D3DGeomShader,0,0);//after this call all sprites disappear } //set shaders context->VSSetShader( vs->mp_D3DVertexShader, 0, 0 ); context->PSSetShader( ps->mp_D3DPixelShader, 0, 0 ); //draw context->DrawIndexed(m_indexCount,0,0); } //sprites void gSpriteDrawer::Draw(gTexture2D* texture,const RECT& dest,const RECT& source, const Matrix& spriteMatrix,const float& rotation,Vector2d& position,const Vector2d& origin,const Color& color) { VertexPositionColorTexture* verticesPtr; D3D11_MAPPED_SUBRESOURCE mappedResource; unsigned int TriangleVertexStride = sizeof(VertexPositionColorTexture); unsigned int offset = 0; float halfWidth = ( float )dest.right / 2.0f; float halfHeight = ( float )dest.bottom / 2.0f; float z = 0.1f; int w = texture->Width(); int h = texture->Height(); float tu = (float)source.right/(w); float tv = (float)source.bottom/(h); float hu = (float)source.left/(w); float hv = (float)source.top/(h); Vector2d t0 = Vector2d( hu+tu, hv); Vector2d t1 = Vector2d( hu+tu, hv+tv); Vector2d t2 = Vector2d( hu, hv+tv); Vector2d t3 = Vector2d( hu, hv+tv); Vector2d t4 = Vector2d( hu, hv); Vector2d t5 = Vector2d( hu+tu, hv); float ex=(dest.right/2)+(origin.x); float ey=(dest.bottom/2)+(origin.y); Vector4d v4Color = Vector4d(color.r,color.g,color.b,color.a); VertexPositionColorTexture vertices[] = { { Vector3d( dest.right-ex, -ey, z),v4Color, t0}, { Vector3d( dest.right-ex, dest.bottom-ey , z),v4Color, t1}, { Vector3d( -ex, dest.bottom-ey , z),v4Color, t2}, { Vector3d( -ex, dest.bottom-ey , z),v4Color, t3}, { Vector3d( -ex, -ey , z),v4Color, t4}, { Vector3d( dest.right-ex, -ey , z),v4Color, t5}, }; auto mp_context = mp_D3D->mp_Context; // Lock the vertex buffer so it can be written to. mp_context->Map(mp_vertexBuffer, 0, D3D11_MAP_WRITE_DISCARD, 0, &mappedResource); // Get a pointer to the data in the vertex buffer. verticesPtr = (VertexPositionColorTexture*)mappedResource.pData; // Copy the data into the vertex buffer. memcpy(verticesPtr, (void*)vertices, (sizeof(VertexPositionColorTexture) * 6)); // Unlock the vertex buffer. mp_context->Unmap(mp_vertexBuffer, 0); //set vertex shader mp_context->IASetVertexBuffers( 0, 1, &mp_vertexBuffer, &TriangleVertexStride, &offset); //set texture mp_context->PSSetShaderResources( 0, 1, &texture->mp_SRV); //set matrix to shader mp_context->UpdateSubresource(mp_matrixBuffer, 0, 0, &spriteMatrix, 0, 0 ); mp_context->VSSetConstantBuffers( 0, 1, &mp_matrixBuffer); //draw sprite mp_context->Draw( 6, 0 ); }

• Please Help with ATI Radeon 4250 and Xinerama

  - by Luis Enrique

  I am using ubuntu 11.10 fresh install and I am having problems making the second screen to work, I remember before I was able to do it by extending the desktop to a larger number like 3840 X 1080 but since I am new I completely forgot how to do it, Now I have a philips 230 E monitor full 1920 X 1080 and a Toshiba tv HDMI and I want to activate the second monitor to be able to use Xinerama but I don't know how to go about this, I want to keep the Phillips as a primary monitor since it's the smaller one and use the TV from time to time to play videos movies and presentations. I installed all the additional drivers and don't know what else to do. I would prefer if I can use a list of exact commands to copy and paste onto the terminal since that is all I know how to use LOL . Thank you so much for your help. If you need more details of my mother board or video card or cpu just ask thank you. Luis

• Homepage 301 Redirect to SSL Homepage

  - by user33692

  I'm hoping somebody might be able to provide a bit of advice on an issue I am having. I have 1 site where we implemented a 301 redirect on the homepage from http to https. We have links on the homepage to other parts of the site that are not under SSL (in fact there is only one other page under SSL). When I go to our webmaster account I notice that we are not being provided with any webmaster information (search queries, backlinks) related to our homepage under SSL. I performed a Fetch Google on the homepage and the information it returned is: HTTP/1.1 301 Moved Permanently Date: Fri, 08 Nov 2013 17:26:24 GMT Server: Apache/2.2.16 (Debian) Location: https://mysite.com/ Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 242 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Content-Type: text/html; charset=iso-8859-1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="https://mysite.com/">here</a>.</p> <hr> <address>Apache/2.2.16 (Debian) Server at mysite.com</address> </body></html> I am worried that the fact that Google Fetch is not getting the correct Title Tags and Meta information from our homepage and that this is hurting our search results. Additionally, I am worried that we need to do something specific with the SiteMap to ensure that Google is correctly indexing all our pages and being able to flow from the https to the http without issues. Does anybody have any advice on how we can correctly set this up or be sure that Google is fetching the correct information?

• How do I do an exact whois search?

  - by brianegge

  When I execute the following whois command on my Ubuntu server, I get all sorts of other domains which contain google.com in the name, but clearly aren't owned by google. As this appears to be some sort of spam, I won't paste the output here. I'd like to check for exactly the name I typed in. I thought the following would work, but it doesn't. What is the proper way to do an exact match? whois -Hx google.com

• Is this SPF record correct for me?

  - by DT

  I'm completely new to Stack Overflow, so Hi! I need to add an SPF record to my site "main.com" (not the real address) to allow an email publishing company "emailpublishers.com" (not the real address) to send emails on my behalf. However, I'm nervous about adding an SPF record because of the havoc it could wreak if done incorrectly. I use Google Apps. I also use "auxiliary.com" to send mail from "main.com." And, of course, I use "main.com" to send mail as well. "auxiliary.com" doesn't have an SPF record. I used Microsofts' and OpenSPF's wizards to generate the following SPF entry. Does it seem to be correct for me? "v=spf1 a mx ip4:55.55.555.55 mx:alt1.aspmx.l.google.com mx:alt2.aspmx.l.google.com mx:aspmx.l.google.com mx:aspmx2.googlemail.com mx:aspmx3.googlemail.com mx:aspmx4.googlemail.com mx:aspmx5.googlemail.com a:auxiliary.com include:_spf.google.com include:auxiliary.com mx:auxiliary.com include:emailpublishers.com mx:emailpublishers.com ~all" However, my host MediaTemple says in a knowledge base article to use: v=spf1 a:main.com/20 ~all So that added to my confusion. Thanks a lot!

• Easy solution to monitoring & blocking connections to non-malicious services, IP's, and tracking companies

  - by binarybunny

  Our family lives in the middle of nowhere, so the only high-speed internet available is Verizon's 3G mobile broadband. We have the highest package available, yet continually go over the 10GB limit and get charged $10 every 1GB we go over. We run a business from home, so stopping when we hit the limit is not an option. I've found the majority of connections are to Google, Microsoft, Akamai, Facebook, and other web service companies (mainly google). I know these are harmless connections, but when it costs money for them to monitor our web activity it becomes a serious problem. Here's some things I've done, but I'm sure there's something else that could help before blocking a huge set of IP ranges: stopped using windows (on my machine) use MVPS host file on all computers use firefox on all computers (with don't track me option) ad block plugin on all browsers blocking google updates blocking windows updates block images in browsers (when possible) use comodo (paranoia-level style of blocking..) virus-free computers with ESET NOD32 bought router and installed dd-wrt in attempt to block connections more diligently (and throttle bandwidth if it comes to that) Anything I'm missing? I know Google analytics is on almost all websites, as well as FB like buttons but I would like to be able to stop these connections without blocking use of google services like gmail, etc. Any ideas?

• Listen to Local FM Radio in Windows 7 Media Center

  - by DigitalGeekery

  If you have a supported tuner card and connected FM antenna, you can listen to your favorite local over-the-air FM stations in Windows 7 Media Center. Before the FM radio option will be available in Windows Media Center, you’ll need to have a TV or Radio tuner card installed and configured. If you have a TV tuner card installed, you may already have a Radio tuner as well. Many TV tuner cards also have built in FM tuners. Open Windows Media Center, scroll the “Music” and over to “Radio.” Click on “FM Radio.”   The radio will turn on and you’ll see the current station number listed in the white box. Just below are standard “Seek” and “Tune” buttons, as well as “Preset” options. Tuning works just like a typical FM radio. Click on the (-) or (+) buttons to “Tune” or “Seek” up and down the dial. If you already know the frequency of the station, enter the numbers using the numeric keypad on the remote control or keyboard. To save the current station you’re listening to as a preset, click on the “Save as Preset” button. Type in a custom name for your preset station and click “Save.”   Once you set your presets, they will also be available on the main FM Radio screen. The transport controls at the bottom of the screen also allow you to control Volume, Pause, Play, Skip back, and Skip forward. Fast Forward and Rewind, however, are not supported.   This is a nice option if you’d like to listen to your local FM favorites on your computer, especially if those stations aren’t available online. If you don’t have an FM tuner and want to listen to thousands of online radio streams, check out our article on RadioTime in WMC.

• DVI+HDMI out, at startup only HDMI is available

  - by Alasjo

  I have my computer next to my hdtv. The main screen is connected via DVI while the tv is connected via HDMI. If I start the computer without the HDMI plugged in, everything is ok: I see the login screen and sound is output through analog out. But if the HDMI is plugged in before I start the computer, only the tv gets an image (the login screen), the main screen is black or at some times purple, but even after login the main screen is black. Also sound is still output through analog out. Not sure whether it's a hw issue, or an Ubuntu issue, or a combined hardware/Ubuntu compatibility issue (Sandy Bridge). This is my setup: Ubuntu 11.10 Oneiric Ocelot (64bit) ASUS P8H67-M LE Intel Core i3-2100 I don't have any custom video settings, my main screen is recognized properly when HDMI is not plugged in at startup. Cheers.

• Blocking 'good' bots in nginx with multiple conditions for certain off-limits URL's where humans can go

  - by Glenn Plas

  After 2 days of searching/trying/failing I decided to post this here, I haven't found any example of someone doing the same nor what I tried seems to be working OK. I'm trying to send a 403 to bots not respecting the robots.txt file (even after downloading it several times). Specifically Googlebot. It will support the following robots.txt definition. User-agent: * Disallow: /*/*/page/ The intent is to allow Google to browse whatever they can find on the site but return a 403 for the following type of request. Googlebot seems to keep on nesting these links eternally adding paging block after block: my_domain.com:80 - 66.x.67.x - - [25/Apr/2012:11:13:54 +0200] "GET /2011/06/ page/3/?/page/2//page/3//page/2//page/3//page/2//page/2//page/4//page/4//pag e/1/&wpmp_switcher=desktop HTTP/1.1" 403 135 "-" "Mozilla/5.0 (compatible; G ooglebot/2.1; +http://www.google.com/bot.html)" It's a wordpress site btw. I don't want those pages to show up, even though after the robots.txt info got through, they stopped for a while only to begin crawling again later. It just never stops .... I do want real people to see this. As you can see, google get a 403 but when I try this myself in a browser I get a 404 back. I want browsers to pass. root@my_domain:# nginx -V nginx version: nginx/1.2.0 I tried different approaches, using a map and plain old nono if's and they both act the same: (under http section) map $http_user_agent $is_bot { default 0; ~crawl|Googlebot|Slurp|spider|bingbot|tracker|click|parser|spider 1; } (under the server section) location ~ /(\d+)/(\d+)/page/ { if ($is_bot) { return 403; # Please respect the robots.txt file ! } } I recently had to polish up my Apache skills for a client where I did about the same thing like this : # Block real Engines , not respecting robots.txt but allowing correct calls to pass # Google RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0\ \(compatible;\ Googlebot/2\.[01];\ \+http://www\.google\.com/bot\.html\)$ [NC,OR] # Bing RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0\ \(compatible;\ bingbot/2\.[01];\ \+http://www\.bing\.com/bingbot\.htm\)$ [NC,OR] # msnbot RewriteCond %{HTTP_USER_AGENT} ^msnbot-media/1\.[01]\ \(\+http://search\.msn\.com/msnbot\.htm\)$ [NC,OR] # Slurp RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5\.0\ \(compatible;\ Yahoo!\ Slurp;\ http://help\.yahoo\.com/help/us/ysearch/slurp\)$ [NC] # block all page searches, the rest may pass RewriteCond %{REQUEST_URI} ^(/[0-9]{4}/[0-9]{2}/page/) [OR] # or with the wpmp_switcher=mobile parameter set RewriteCond %{QUERY_STRING} wpmp_switcher=mobile # ISSUE 403 / SERVE ERRORDOCUMENT RewriteRule .* - [F,L] # End if match This does a bit more than I asked nginx to do but it's about the same principle, I'm having a hard time figuring this out for nginx. So my question would be, why would nginx serve my browser a 404 ? Why isn't it passing, The regex isn't matching for my UA: "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.30 Safari/536.5" There are tons of example to block based on UA alone, and that's easy. It also looks like the matchin location is final, e.g. it's not 'falling' through for regular user, I'm pretty certain that this has some correlation with the 404 I get in the browser. As a cherry on top of things, I also want google to disregard the parameter wpmp_switcher=mobile , wpmp_switcher=desktop is fine but I just don't want the same content being crawled multiple times. Even though I ended up adding wpmp_switcher=mobile via the google webmaster tools pages (requiring me to sign up ....). that also stopped for a while but today they are back spidering the mobile sections. So in short, I need to find a way for nginx to enforce the robots.txt definitions. Can someone shell out a few minutes of their lives and push me in the right direction please ? I really appreciate ANY response that makes me think harder ;-)

• Different nginx rules based on referrer

  - by juana

  I'm using WordPress with WP Super Cache. I want visitors who come from Google (That inlcudes all country specific referrers like google.co.in, google.co.uk and etc.) to see uncached contents. There are my nginx rules which are not working the way I want: server { server_name website.com; location / { root /var/www/html/website.com; index index.php; if ($http_referer ~* (www.google.com|www.google.co) ) { rewrite . /index.php break; } if (-f $request_filename) { break; } set $supercache_file ''; set $supercache_uri $request_uri; if ($request_method = POST) { set $supercache_uri ''; } if ($query_string) { set $supercache_uri ''; } if ($http_cookie ~* "comment_author_|wordpress|wp-postpass_" ) { set $supercache_uri ''; } if ($supercache_uri ~ ^(.+)$) { set $supercache_file /wp-content/cache/supercache/$http_host/$1index.html; } if (-f $document_root$supercache_file) { rewrite ^(.*)$ $supercache_file break; } if (!-e $request_filename) { rewrite . /index.php last; } } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html/website.com$fastcgi_script_name; include fastcgi_params; } } What should I do to achieve my goal?

• Is meta description still relevant?

  - by Jeff Atwood

  I received this bit of advice about the meta description tag recently: Meta descriptions are used by Google probably 80% of the time for the snippet. They don’t help with rankings but you should probably use them. You could just auto generate them from the first part of the question. The description tag exists in the header, like so: <meta name="Description" content="A brief summary of the content on the page."> I'm not sure why we would need this field, as Google seems perfectly capable of showing the relevant search terms in context in the search result pages, like so (I searched for c# list performance): In other words, where would a meta description summary improve these results? We want the page to show context around the actual search hits, not a random summary we inserted! Google Webmaster Central has this advice: For some sites, like news media sources, generating an accurate and unique description for each page is easy: since each article is hand-written, it takes minimal effort to also add a one-sentence description. For larger database-driven sites, like product aggregators, hand-written descriptions are more difficult. In the latter case, though, programmatic generation of the descriptions can be appropriate and is encouraged -- just make sure that your descriptions are not "spammy." Good descriptions are human-readable and diverse, as we talked about in the first point above. The page-specific data we mentioned in the second point is a good candidate for programmatic generation. I'm struggling to think of any scenario when I would want the Google-generated summary, that is, actual context from the page for the search terms, to be replaced by a hard-coded meta description summary of the question itself.

• PHP Mail() to Gmail = Spam

  - by grantw

  Recently Gmail has started marking emails sent directly from my server (using php mail()) as spam and I'm having problems trying to find the issue. If I send an exact copy of the same email from my email client it goes to the Gmail inbox. The emails are plain text, around 7 lines long and contain a URL link in plain text. As the emails sent from my client are getting through fine I'm thinking that the content isn't the issue. It would be greatly appreciated if someone could take a look at the the following headers and give me some advice why the email from the server is being marked as spam.

• Where does Picasa store albums?

  - by Dan

  For people searching, the question might also be phrased: How do I restore Picasa albums from backup? When I reinstalled my computer and restored my photos from backup, some of my albums showed up, but many didn't. I've found the following info: Picasa on Windows stores (stored?) album info in these places: Vista: C:\Users\<myaccount>\AppData\Local\Google\Picasa2Albums\ XP: C:\Documents and Settings\<myaccount>\Local Settings\Application Data\google\Picasa2Albums\ I restored that folder and was still missing many of my albums. That folder also contained a folder of backups, but the most recent one was from a long time ago and I've created albums since then. According to https://support.google.com/picasa/bin/picasa.google.com/support/bin/static.py?hl=en&page=release_notes.cs, since the Dec 8, 2011 build, Picasa saves album info in .ini file(s). This probably explains the albums that I do see. http://katelharrison.blogspot.com/2012/01/how-to-restore-picasa-albums-mac.html has some great info on restoring albums on Macs, but the folder structure seems to be different there than on Windows.

Is there any way to contact Google and ask them what causes this? Update: I have set up openDKIM on my server, everything works, gmail message headers say that dkim=pass, which means everything is set up correctly. Messages still end up in Spam folder.

  Hi, I am using Solr (1.4) AutoSuggest feature using termsComponent. Currently, if I type 'goo' means, Solr suggest words like 'google'. But I would like to receive suggestions like 'google, google alerts, ..' . ie, suggestions with single and multiple terms.

• SPF record for Gmail?

  - by Chris

  I have DNS, with a SPF TXT record, configured for a domain name. The primary user of the domain name now needs to be able to send both from our SMTP servers, and also from her GMail account. I've seen all the information about adding "include:_spf.google.com" to the SPF TXT record, but, as I look into it, it appears that record is outdated. In particular, I had the user send me a test message, and note that it was: Received: from mail-la0-f50.google.com (mail-la0-f50.google.com [209.85.215.50]) However, _spf.google.com doesn't list that IP address: $ dig +short _spf.google.com txt "v=spf1 ip4:216.239.32.0/19 ip4:64.233.160.0/19 ip4:66.249.80.0/20 ip4:72.14.192.0/18 ip4:209.85.128.0/17 ip4:66.102.0.0/20 ip4:74.125.0.0/16 ip4:64.18.0.0/20 ip4:207.126.144.0/20 ip4:173.194.0.0/16 ?all" (Note that a 209.85.21*8*.0 network is listed, but not 209.85.21*5*.0.) Is there a better way to enable sending from GMail? This user sends to at least one recipient with a strict SPF policy that bounces mail not from a designated host... Many thanks!

• Acer Revo (ION platform) + Maverick + 5.1 surround over HDMI

  - by Oli

  I've had a turbulent relationship with my media centre box. Every upgrade I perform on it seems to bring a brand new set of audio issues (the opposite of my desktop where things seem to get better and better). It's a Acer Revo 3600. That's basically an low-end Intel Atom chip with a Nvidia 9400M onboard. On paper that's perfect for something like a media centre. But having just upgraded to Maverick, the sound properties box only wants to offer me stereo sound over HDMI. The exact setup goes: Revo - Onkyo AV receiver - LG TV. The Onkyo box strips off the audio (supporting 7.1 -- though we're only using 6 speakers) and feeds the video onto the TV. I'd like to get to a point where Ubuntu thinks it's doing 5.1 over HDMI, upmixing stereo to 6ch and supporting DTS/AC3 (through Boxee). I've had this working before but it's frankly been a bit of a hacktastrophe. The audio chip is recognised as Nvidia MCP79/7A HDMI in alsamixer if that helps.

• DNS zone file SPF configuration to support sending mail from multiple servers and gmail

  - by Tauren

  I want to configure SPF on a domain to allow mail to be sent from: the x.com website server (x.com and www.x.com - both at same IP) it's MX servers (smtp.x.com, mx.x.com, mail.x.com) another server that isn't listed as an MX server (somehost.x.com) via gmail using an account that has authenticated use of [email protected] Will this zone file work? If not, what are the problems with it? $ttl 38400 @ IN SOA ns1.x.com. hostmaster.x.com. ( 201003092 ; serial 8H ; refresh 15M ; retry 1W ; expire 1H ) ; minimum @ NS ns1.x.com. @ NS ns2.x.com. @ MX 10 mx.x.com. @ MX 20 smtp.x.com. @ MX 30 mailhost.x.com. ; SPF records @ IN TXT "v=spf1 a mx a:somehost.x.com include:_spf.google.com ~all" mx IN TXT "v=spf1 a -all" smtp IN TXT "v=spf1 a -all" mailhost IN TXT "v=spf1 a -all" Questions: Is _spf.google.com the right thing to include for gmail.com, or is it only for Google Hosted Apps? If only for Google Apps, what should I include to send from gmail.com? If mail shouldn't be sent from anywhere else, is it safe to use -all instead of ~all? Does it make sense to add specific SPF records for each of the mail servers? Any other problems with the zone file? I want to confirm these things before making changes to my zone file. The file has SPF configured basically the same now, just without google.com and somehost, but I want to make sure I won't break things when I change it.

• Multi language site - use of canonical link and link rel="alternate"

  - by julia

  I keep reading everywhere that if you have a multilanguage site, where the same page appears in, say, French and English, then this is considered as duplicate content by google. It is written that using canonical link is the solution, but I do not understand how to use it in this case. Should I: Choose either French URL or English URL to be the canonical (main) one, and where I will place the canonical link? If so, how do I decide which of the two URLs must be canonical? both languages are important to me and I want the content under both languages to be indexed by google and served to the user, depending on the language in which he searches. OR should I place a canonical link on both French and English URLs? If so, then I do not understand the meaning of using the canonical link? In this case would both URLs be indexed, are both of them considered as "important" by google and not duplicates? Also I read that link rel="alternate" can be used to indicate to google that, for example the French URL is the French-language equivalent of the English page. This makes sense and I understand how to use such links, but how are they combined with canonical links? Should I define both the canonical URL AND specify rel="alternate" in both URLs? Could someone help me to clarify this, cause I'm stuck with this and can't seem to find a good-enough explanation in different sources.
