  • mod_security: How to allow ssh/http access for admin?

    - by mattesque
    I am going to be installing mod_security on my AWS EC2 Linux instance tonight and need a little help/reassurance. The only thing I am truly worried about right now is making sure my (admin) access to the instance and webserver is maintained w/o compromising security. I use ssh (port 22) and http (80) to access this and I've read horror stories from other EC2 users claiming they were locked out of their sites once they put up a firewall. So my question boils down to: What settings should I put in the mod_security conf file to make sure I can get in on those ports? IP at home is not static. (Hence the issue) Thanks so, so, so much.

  • Remote connect to mysql server?

    - by LF4
    I've been trying to figure out why I keep getting this error when I try to connect to the MySQL server with the following commands. $~ mysql -u username -h SQLserver -p Enter password: ERROR 1045 (28000): Access denied for user 'username'@'myIP' (using password: YES) I've done the following: Port is open in the firewall other wise I wouldn't get the error it'd just timeout. MySQL server not running with skip-networking or bind-address username has host as '%' and I can connect locally so the password is correct.

  • Citrix has issues resolving network shares

    - by George
    We are having this weird issue with our Citrix (version 4.5) server (sitting on Windows 2003 r2), where a couple users have issues resolving single shared network drive. We use a logon script to map all shared drives. The weird part is that of 3 shared drives, users can access 2, but the 3rd one goes to the old server (even though the logon script points to the new server). And that issues is limited to a few users. I had them log off and re-loggin to no success. It happens just in Citrix. The file server, that is being accessed, is Windows 2008 R2. Like I said we use a logon script to map the network drive. I understand I might be a little confusing, I will gladly reword the post.

  • Redirect websockets to port?

    - by DigitalMan
    So, I've got a WebSocket server in C++, that is a completely stand-alone entity - handles header parsing, receiving, sending, all of it on its own, listening directly to the port. Problem is, it needs to run on a server alongside Apache, and that's a bit of a problem. Now, there was a solution here to a similar issue involving mod_proxy, but I'm hoping I can intercept and redirect WebSocket communication before Apache even knows about it, possibly with iptables. So the question is, is it possible to direct traffic bound for chat.mysite.net to a WebSocket server on, say, port 8080, while anything else headed to mysite.net proceeds as expected to Apache?

  • How to use filegroups for DB split?

    - by Robin Jain
    In my project I have one DB used for everything. I want it to break into two databases. Static tables having look up values are to be stored in one DB and another DB would be having tables with dynamic data. My problem is that how would I use foreign key constraint in between those two DBs. Can someone help me out and suggest a way to proceed, better if I'm provided an example for the same. I thought of using synonyms for tables and then constraints on synonyms. but later I came to know that synonyms couldn't be used for constraints. I need to maintain relationships among the tables from both DB as the issue is with update, with a new release I just want to update look up tables and for the same I want to split my DB. I want to know how FileGroups could be used for this.

  • Problems using "at" with Apache

    - by Alex Padgett
    I'm trying to use a PHP script to create at jobs, but when it comes time to execute the jobs, nothing seems to be happening. I've tried to output any errors to log files, but have had no luck. It seems obvious that it's a permissions issue, because when I set apache to run as my personal user, everything works fine. However, when I exec wget directly from PHP, everything works fine so it seems that apache has the correct permissions to use it. The problem appears to be when using at in conjunction with apache. So I need to find a way to make this work with apache running as its own user. Here is the command I'm using: echo "wget -qO- http://example.com/" | at now + 1 minute 2>&1 Any ideas? EDIT: Apache can create the at jobs, it just seems that when they execute nothing is happening.

  • Is my htaccess setting hurting SEO?

    - by Ramanonos
    I have a site that I have redirecting to https. I do this to leverage wildcard SSL for my password protected pages. Everything seems to work fine with testing. For example, whether you type in http or www, you always get redirected to the SSL https... That said, I have about 200-300 external backlinks -- many high quality, yet google webmaster (along with SEOMoz), shows I have just 4... Huh? I'm embarrassed to say I just discovered this. This has led me to hypothesize that maybe my settings in htaccess is messed up, so google isn't recognizing a link because it's recorded on another site as http, instead of https. Maybe? At any rate, here is my simple htaccess setting for 301 www to http, and from http to https. RewriteCond %{SERVER_PORT} !443 RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] RewriteRule ^(.*)$ http://example.com/$1 [L,R=301] RewriteCond %{SERVER_PORT} 443 RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] RewriteRule ^(.*)$ https://example.com/$1 [L,R=301] Like I said, everything works fine for redirect over https, so I'd rather not screw up what works. On the other hand something is very wrong with google finding all my back links, so I need to fix something... I'm just wondering that maybe google isn't picking up a my backlinks from other websites recording me as http because I'm at https. Maybe google doesn't care and it's some other issue. Am I barking up the right tree? If so any quick fixes? Thanks as always!

  • How to remove permanent map of a network drive on OS X Lion?

    - by Flijfi
    Some time ago I mapped a network drive on my Snow Leopard Mac, which was upgraded to Lion. The network drive is not active any more and I receive popups all the time with the error: There was a problem connecting to the server XXXX. I have no idea how I configured at the time. I may have included a mount command, in a config file but I don't know any more where I did it. I reviewed the Preferences/Account/Login items and there is no permanent mapping there. OSX is updated as Nov 27,2011 and the issue is not related to the upgrade to Lion itself but to a misconfiguration. Any help will be greatly appreciated. (If you have the opposite problem, here is the link to solve it: Permanently map a network drive on Mac OS X Leopard)

  • How to know or change the size of the Windows Event Log from a program under Windows XP? [closed]

    - by ahmd1
    I ran into a weird problem on a Windows XP system. My local service app logs its diagnostic messages into the Windows Event Log, so at some point those messages stopped being logged. I thought that the issue was in my code, but then I discovered that other processes can't log messages either. So I was wondering, is there a limit on the Windows Event Log size? PS. I guess I need to write this specifically -- I need to know/change the size from a command line or an API.

  • Recommended Free DNS hosting for my webserve on a dynamic IP? [closed]

    - by JSchwartz
    I have finished a webserver project (for school) and the professor wants to be able to "test it" from home whenever he is free - this means I need to provide his with the URL to my webserver (which is fine). The only issue is that my IP-Address is dynamic (changes almost everyday) and I would rather not have to email him everytime - nor do I want him to try when it isn't working ... So I was looking into alternative solutions like DNS hosting (I hope that is the right terminology), so I could provide something static for him to connect to ... problem is I have never done this before... Are there any recommeneded free ones? Does Google or someone provide something good? I found http://www.no-ip.com/ which seems like it does what I want... Any feedback would be appreciated. Thanks,

  • How can I make windows not mount a drive when it is plugged in?

    - by heavyd
    Due to my employer's IT policy, I'm not allowed to have any kind of MP3 playing software on my computer. I do however like to plug my iPod into my computer to keep the battery charged during working hours. Normally, I plug the iPod in, Windows mounts the drive, then I have to go in and eject the drive so I can run my iPod normally while still keeping it charged. Is there anyway I can keep Windows from mounting the drive (and this drive only, I still use my USB flash drive a lot) from auto-mounting? Update: Maybe this is more of an iPod issue, but specifically I would like for the iPod to not display the "Do not disconnect" message when plugged in.

  • Efficiency of iterators and alternatives? [migrated]

    - by user48037
    I have the following code for my game tiles: std::vector<GameObject_Tile*>::iterator it; for(int y = 0; y < GAME_TILES_Y; y++) { for(int x = 0; x < GAME_TILES_X; x++) { for (it = gameTiles[x][y].tiles.begin() ; it != gameTiles[x][y].tiles.end(); ++it) {}}} tiles is: struct Game_Tile { // More specific object types will be added here eventually vector<GameObject_Tile*> tiles; }; My problem is that if I change the vector to just be a single GameObject_Tile* instead and remove the iterator line in the loop I go from about 200fps to 450fps. Some context: The vector/pointer only contains one object in both scenarios. I will eventually need to store multiple, but for testing I just set it to a single pointer. The loop goes through 2,300 objects each frame and draws them. I would like to point out that if I remove the Draw (not seen int he example) method, I gain about 30 frames in both scenarios, the issue is the iteration. So I am wondering why having this as a vector being looped through by an iterator (to get at a single object) is costing me over 200 frames when compared to it being a single pointer? The 200+ frames faster code is: std::vector<GameObject_Tile*>::iterator it; for(int y = 0; y < GAME_TILES_Y; y++) { for(int x = 0; x < GAME_TILES_X; x++) { //gameTiles[x][y].tiles is used as a pointer here instead of using *it }} tiles is: struct Game_Tile { // More specific object types will be added here eventually GameObject_Tile* tiles; };

  • Keeping shortcuts in Windows XP current (automatically)?

    - by NT
    Hello, In Windows XP Pro (SP2), there seems to be no way to have shortcuts automatically updated so they can stay connected to their target files or folders after the latter have been moved or renamed. So I'm looking for more efficient ways of reconnecting broken shortcuts with their moved or renamed targets than manually deleting them and re-creating new ones (this can be quite a chore if you reorganize your files and folders often, resulting in a lot of shortcuts to fix); and I'd like to find out if there are any PC programs that can monitor shortcuts on Windows XP and automatically fix them when their target files or folders get moved or renamed. Any suggestions on this issue will be greatly appreciated. Thank you, NT

  • dell E6500 laptop will not hibernate/standby

    - by Mark Schultheiss
    I am using a Dell E6500 laptop with windows XP on it, it was originally tagged/installed with Windows Vista. My issue is, when I close the lid, it will not either Hibernate or Standby. If I close the lid with either of these options, I then have to startup from scratch, and anything I had open is not open. I just want to close the lid, have it keep what I have running, not use power util I open the lid again and start it up (with the stuff still open I had open of course). Suggestions?

  • Websites not working with Opera 11.00, major bugs

    - by s hanley
    Sites like ebay and even superuser stop working properly when I use opera 11.00. Menus stop working everywhere from ebay to godaddy. Hovering on a menu item doesn't expand it, no sub menu slides out. This makes a large number of very popular websites unusable. Am I right in assuming this is a javascript issue? I use opera for the turbo feature (I have tested opera with and without turbo so it's not turbo's fault) because I'm on mobile broadband until I get my phone line sorted out. Turbo helps me save money, as well as allowing me to surf at a sane speed. Is there a firefox or chrome equivalent to opera turbo that doesn't cost money? I'm using Opera 11.00, build 1156.

  • Rotate camera with mouse? [closed]

    Once again, using tutorial 10 at NeHe. I want the code if (keys[VK_RIGHT]) // Is The Right Arrow Being Pressed? { yrot -= 1.5f; // Rotate The Scene To The Left } if (keys[VK_LEFT]) // Is The Left Arrow Being Pressed? { yrot += 1.5f; // Rotate The Scene To The Right } and if (keys[VK_PRIOR]) { lookupdown -= 1.0f; } if (keys[VK_NEXT]) { lookupdown += 1.0f; } to be done with the mouse instead of left/right arrow and Page Up/ Page Down. I tried everything I could think of. Can anyone help? EDIT: I tried using WM_MOUSEMOVE message. I just could not figure it out. EDIT2: I am using pure OpenGL to do this. No window management system or other libs such as GLUT, GLFW, SDL, SFML etc. Just OpenGL. OpenGL and GLEW. EDIT: Issue has been solved.

  • Ubuntu 11.10 Random reboots how to find root cause?

    - by Indigo42
    All, This issue started with 11.04, I upgraded to 11.10 this week in hopes it would correct it, but after a few days it happened again.. A few times a day, randomly, my monitors will go black and the machine will come back in the post screen and boot up again. Sometimes it boots up properly, sometimes it boots to disk scan (I understand why...the machine just died with a bunch of stuff open) and sometimes it takes several cycles of this to come up. I connected to the system with my laptop and tailed dmesg, syslog, kern.log, and Xorg.0.log. I also ran a cat /proc/kmesg. Nothing is showing up in any of these log files when it happens..it's just like someone has pulled the plug. I just got through running 4 hours of the memory test with no errors. I have a AMD Phenom 9850 Quad-Core Processor and Nvida 9500GT graphics card. This system has been stable for like 4 years. I'm thinking it might be a hardware problem, but how do I find out? Thanks,

  • Maxivista vs. Synergy vs. hardware KVM switches [closed]

    - by GetFree
    I have 2 PCs on my desk, each one with its own screen, mouse and keyboard. And it's a pain moving from one PC to the other (even though they are one foot away from each other). So, it's time to change to different approach: KVM switches. What would you recommend for a setup like mine? I dont need to change monitors since they are both in front of me. I just need a way to change mouse and keyboard. I use Windows on both PCs and money is not an issue if it worth it. What would be the best option for a seamless integration of the two PCs? Edit: What about other software similar to Synergy, like Input Director? What's more convenient in your experience?

  • Setup of Citrix-Client (xenapp) doesn't work on Windows Vista Utimate

    - by Ice
    I have a notebook with a fully patched Vista Ultimate and there was a Citrix ica-client installed for access on our citrix-server(s). Once the client couldn't access the server – it took so much time ( 5 min) and everything froze. I did an uninstall und cleaned up the registry. But now it's not possible to reinstall a xenapp-client even the newest directly from www.citrix.com. What could be the reason? How to fix this issue? PS: At the moment I start a vm with an XP and the citrix-access runs like a charm, but that only could be a work-a-round.

  • How do I get any number of links to space evenly? [migrated]

    - by Aerodynamo
    Alright, so here is the situation... Say I have a navbar for a site, and I allow users to change the number of links they want on this navbar. This means they could have 3, 5, 10, etc. What I want to do is make it so that if one link is up, it only takes up, say, 1/5th of the space on the navbar. If I weren't using borders, I might do something like: width: 18%; padding: 0 1%; However, I have two problems with this: 1) For 4 buttons, that's fine that it doesn't fill up the whole row. It would look ugly if the links were too wide... but when I have 6 or 7 buttons, it's got huge overflow! 2) Since I have borders, I can't use a percentage value for the borders or the widths, because I can't properly estimate how much of the percentage it will be. Now, I know I don't have to use percentage values, but what I would ideally prefer is that the first button is the smallest possible size necessary for all the other buttons to fit properly, meaning that if I have 950px and 6 links, the first link can be about 150px while the others are 160px... that's fine. I want all the other buttons on the navbar to be equally sized, regardless of how many links there are. I also need for it to accept a border... I figure the way to do this is to put a border in the nested div, so that way it doesn't effect the overall width of the button? This is all well and good, but I'm still plagued by the issue of not being able to design a dynamic site using the style I want if I can't get all the nav buttons to fit the width properly. Are there some js tricks I could use? I don't even know... Thanks

  • Apache: multiple domains handling

    - by cache
    So I use following schema to handle multiple sites on my apache: <VirtualHost 192.168.1.100:80> # get the server name from the Host: header UseCanonicalName Off VirtualDocumentRoot /var/www/%0/docs VirtualScriptAlias /var/www/%0/cgi-bin </VirtualHost> Therefore, if a client go to www.example.com, it will actually point to /var/www/www.example.com/doc/, which is good. However, what if the client go to example.com? It will point to /var/www/example.com/doc, which is not what we want. So my question is: is there any better schema for that? Or what should I do to fix the issue? Thanks!
