  • SAMBA and Linux ACLs -- "Permission denied" on write to share but file written nevertheless

    - by MCH
    I set up a writable share directory "/home/net/share" with acl like this: sudo mkdir -p "/home/net/share" sudo setfacl -m "u:localuser:rwx,u:remoteuser:rwx,g:users:rwx" "/home/net/share" My /etc/samba/smb.conf looks like this: [global] workgroup = w server string = server security = user load printers = no log file = /var/log/samba/%m.log max log size = 50 dns proxy = no printing = bsd printcap name = /dev/null disable spoolss = yes encrypt passwords = true invalid users = nobody root follow symlinks = yes wide links = yes [share] comment = Writable by localuser and remoteuser path = /home/net/share valid users = remoteuser read only = no public = no printable = no Locally, localuser and remoteuser have user accounts and smbpasswds and can both read, create and delete files in /home/net/share. But when I log on from a different machine (like this: sudo mount -t cifs //server/share mountpoint/ -o username=remoteuser ), I get "Permission denied" both when trying to create directories and files, oddly though, it does create files (not directories!) despite these messages! How can I get this working?

  • Remove Content-Length header in nginx proxy_pass

    - by Luc
    I use nginx with proxy path directive. When the application to which the request is proxied return a response, it seems nginx add some header containing the Content-Length. Is that possible to remove this additional header ? UPDATE I have re-installed nginx with the more_headers module but I still have the same result. My config is: upstream my_sock { server unix:/tmp/test.sock fail_timeout=0; } server { listen 11111; client_max_body_size 4G; server_name localhost; keepalive_timeout 5; location / { more_clear_headers 'Content-Length'; proxy_pass http://my_sock; proxy_redirect off; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; } }

  • How can I send a Wake on Wireless LAN (WoWLAN) / Wake on Demand request manually?

    - by pioto
    This is similar to, but not the same as, http://serverfault.com/questions/1721/is-wireless-wake-on-lan-possible. I know it is supposed to be possible. The question is, how do I do whatever the AirPort Basestation will do? All I can find so far is that supposedly I need to send something with Wireless Multimedia Extensions (WMM): Basically, I want to be able to wake up my Mac Mini remotely, probably using my Linux laptop. Does anyone know of a tool to do this? Basic Wake on LAN tools do not seem to be the right thing. I don't need the Sleep Proxy Service bit, because I already know the MAC address of the system I want to wake up.

  • iPhone: Add background button to view when UITableView has no cells

    - by Nic Hubbard
    I have a UITableViewController, when there is no data to populate the UITableView, I want to add a button, which uses an image. So, rather than the user seeing a tableview with no records, they will see an image that says, "No records have been added, Tap to add one", then they click and we create a new one. I assumed I would just hide the UITableView, then create the button, but I never see the button. Here I am using: if ([[fetchedResultsController sections] count] == 0) { self.tableView.hidden = YES; // Create button w/ image UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(0, 0, 100, 50); [btn setImage:[UIImage imageNamed:@"no-rides.png"] forState:UIControlStateNormal]; [self.view addSubview:btn]; } Ideas on why I would never see the button? When I show this view, it seems to have a transparent background for a second, then changes white...

  • Limiting and redirect port access with useragent

    - by linuxcore
    I'm trying to write iptables string match rule To block http://domain.com:8888 and https://domain.com:8888 when it matches the supplied string in the rule. And another rule to redirect the ports also from 8888 to 7777 I tried following rules but unfortunately didn't work iptables -A INPUT -p tcp -s 0.0.0.0/0 -m string --string linuxcore --algo bm --sport 8888 -j DROP iptables -t raw -A PREROUTING -m string --algo bm --string linuxcore -p tcp -i eth0 --dport 8888 -j DROP iptables -t nat -A PREROUTING -p tcp --dport 8888 -m string --algo bm --string "linuxcore" -j REDIRECT --to-port 7777 iptables -A INPUT -t nat -p tcp --dport 8888 -m string --algo bm --string "linuxcore" -j DROP I want to do this from iptables not the webserver because the server may not have a webserver and those ports are working on internal proxy or something like ..etc

  • why Apache with ssl but back end weblogic without ssl works?

    - by huangli
        Hello everyone. my question is very simple . The link below is a picture about my architecture. https://docs.google.com/open?id=0BxSXbpgYIZVOR212RVk4ZDN1Sm8.      The pic above shows the architecture right now and it works correctly ! which means I could visit apache with url https//apchehost:8080, could not visit the web app with https served by weblogic but I could visit these app with https served by Apache(Apache is proxy server).      My question is why the Apache is configured with ssl but weblogic without ssl works ? I think weblogic should also configured with ssl . If this works , what about security level ? Is the ssl really works if only Apache configured with ssl but Weblogic without it ? Thanks . condition: Apache 2.2.17 with weblogic module mod_wl_22.so Weblogic: 10.3 OS: Windows server 2003

  • Squid3 not working. Access denied

    - by Nitish
    I installed SQUID3 on a Linux machine with two ethernet interfaces (eth0 and eth1). I used the default settings in the squid.conf file and uncommented the two lines acl localnet src 192.168.0.0/16 and http_access allow localnet. eth0 is connected to a router, which provides Internet access. It is assigned an IP 192.168.1.2 by the router. I manually configured eth1 to have an IP address 192.168.5.1. It is connected to a switch. Systems having IP addresses 192.168.5.x are connected to this switch. I ran these two commands for NAT: iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.5.1:3128 iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128 But when I try to access internet from a system having IP 192.168.5.2 through the proxy I get an error that says "Access denied". What is wrong with my configuration?

  • custom UIButton with skewed area in iPhone

    - by sugar
    I want to have a button on a screen with this image. this image is transparent from its corners as you can see here. UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom]; [btn setFrame:CGRectMake(xCo, yCo, kImageSizeWidth, kImageSizeHeight)]; [btn setImage:[UIImage imageNamed:@"aboveImg.png"] forState:UIControlStateNormal]; [btn addTarget:self action:@selector(btnTapped:) forControlEvents:UIControlEventTouchDown]; But the button tap is recognized out side image & i don't want that kind of functionality. I mean tap must be recognized only when it is tapped within image not outside image. How is that possible ? Thanks in advance for sharing your great knowledge. Sagar.

  • Using an image as a border

    - by Tempname
    I am working on an custom container and I need a border for this container. I have a 15x15 image that I am creating a 9-slice border skin with. The issue that I am having is that the border skin does not appear the way that I had hoped it would. Here is a ss of the skin in place. Ideally I should have a transparent box with a 5 pixel border around it. Here is my current testing code: CSS Code: Box { borderSkin: Embed(source="15x15.png", scaleGridLeft="5", scaleGridTop="5", scaleGridRight="10", scaleGridBottom="10"); } MXML Code: <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Style source="MainTest.css"/> <mx:Box id="tw" width="400" height="400"> </mx:Box> </mx:WindowedApplication>

  • Is OpenGL required for my iPhone game?

    - by Ben X Tan
    On an iPhone: If I am writing a game that has multiple levels, with multiple animations (image sequences), jpg and png (transparent), some full screen and some not, some looped and some played once only. What is the best way of doing it? Each level might have up to 10MB of images. Add on to this music, and video (cut scenes). All 2D graphics, no 3D models. Is OpenGL required? Or can this be achieved with Quartz or Core Animation?

  • Why are the external IP of my router not the same as the external IP of my computer

    - by Martin
    I have a standard network setup where all my network devices, both WIFI and ethernet, are connected to the same router. Lately, however, I've been experiencing some very strange behavior. It started as a simple connecting error, when I tried to reach an FTP server using the external IP. Of course I went right into one of those CheckMyIP sites, to double check the IP and it turned out to be correct. Then I went into my router setup, which is through a tool called aiport-tool, because I have an Apple Aiport Extreme router. Turns out the router displays a different external IP, and for some reason that external IP works when I try to access the FTP server. Can anyone explain what is going on? Why are the devices connected to the router displaying an incorrect external IP? BTW i have no VPN/proxy setups on any of my devices.

  • gwt not showing the right image

    - by arinte
    I have a gwt image object . In my code I set my visibleRect like this: btnSearch.setVisibleRect(-64,-80,16,16); So when I run my code with firebug the html looks like this: <img border="0" style="width: 16px; height: 16px; background: url(&quot;http://tempest/deltaflow/Content/Images/icon.png&quot;) no-repeat scroll 64px 80px transparent;" src="http://127.0.0.1:8888/trunkui/clear.cache.gif"> Why is the '-' left off? When I edit it with firebug to have the '-' it works fine.

  • Performance of Managed C++ Vs UnManaged/native C++

    - by bsobaid
    I am writing a very high performance application that handles and processes hundreds of events every millisecond. Is Unmanaged C++ faster than managed c++? and why? Managed C++ deals with CLR instead of OS and CLR takes care of memory management, which simplifies the code and is probably also more efficient than code written by "a programmer" in unmanaged C++? or there is some other reason? When using managed, how can one then avoid dynamic memory allocation, which causes a performance hit, if it is all transparent to the programmer and handled by CLR? So coming back to my question, Is managed C++ more efficient in terms of speed than unmanaged C++ and why?

  • Weird Behavior with Jquery image slideshow... Help!

    - by Thomas
    I built a jquery slideshow based on the tutorial found here: http://www.queness.com/post/152/simple-jquery-image-slide-show-with-semi-transparent-caption It seems to be working perfectly fine, except that it behaves strangley right at the beginning when it displays the first image. The first image appears like normal and then flashes, fades to white and disappears completely. After that, the first slide reappears and behaves normally, transitioning to the next image. The slideshow in question is center page on the right: http://www.loftist.com/ I am not a JS developer, so I am not sure how to troubleshoot this problem. Any help would be greatly appreciated, thanks!

  • nginx caching per user agent

    - by Tuinslak
    I'm currently using nginx as reverse proxy with caching enabled. However, the main site has two different layouts, depending on the user-agent (mobile or not). I've tried something similar to this: # mobile users if ($http_user_agent ~* '(iPhone|iPod|mobile|Android|2.0\ MMP|240x320|AvantGo|BlackBerry|Blazer|Cellphone|Danger|DoCoMo|Elaine/3.0|EudoraWeb|hiptop|IEMobile)') { set $iphone_request '1'; } if ($iphone_request = '1') { proxy_cache mobile; } if ($iphone_request = '') { proxy_cache site; } proxy_cache_key "$scheme://$host$request_uri"; proxy_pass http://real-site.tld; However, nginx gives an error, stating proxy_cache can't be used in an if-structure. Any other way to serve from a different cache depending on the browser? Thanks, Tuinslak

  • Trouble with creating WPF window extended on the title area (like Office 2007/2010)

    - by Rikker Serg
    I want to make WPF window extended on the title area (like Office 2007/2010). I implemented DwmWindow (see DwmTest.zip) where I put required stuff. Commonly, it works fine except one disgusting thing: the window appears as white rectangle (see DwmIssue.png) and after a few second this rectangle disappears and the content of the window is shown (see DwmIssueCorrect.png). This bug is essential only for my window. If I remove this lines it works fine (without it aero will not showed on title): HwndSource mainWindowSrc = HwndSource.FromHwnd(handle); if (mainWindowSrc != null) mainWindowSrc.CompositionTarget.BackgroundColor = Colors.Transparent; NativeMethods.MARGINS margins = new NativeMethods.MARGINS(0, 50, 0, 0); NativeMethods.DwmExtendFrameIntoClientArea(handle, margins); How can I eliminate this white rectangle? (To run a sample DwmTest.zip WinVista/7 with DWM enabled and .NET 4.0 is required. To compile sample you will need Visual Studio 2010)

  • How to manage configuration software installations of non-domain Windows XP machines?

    - by Digi
    I have a large set of unattended Windows XP machines who are not connected to a domain or even to each other. I am struggling to find any tools out there that I can use to deal with them in one application. I am hoping to find software that I can perhaps install a client on each machine, then have it essentially proxy out configuration information and possibly commands (install, uninstall, stop service, etc) across the whole network. The closest I've come is Nagios and its client, but it cannot be used to push files through and run commands remotely. Any suggestions?

  • Resizing an image with alpha channel

    - by Hafthor
    I am writing some code to generate images - essentially I have a source image that is large and includes transparent regions. I use GDI+ to open that image and add additional objects. What I want to do next is to save this new image much smaller, so I used the Bitmap constructor that takes a source Image object and a height and width, then saved that. I was expecting the alpha channel to be smoothed like the color channels, but this did not happen -- it did result in a couple of semitransparent pixels, but overall it is very blocky. What gives? Using img As New Bitmap("source100x100.png") ''// Drawing stuff Using simg As New Bitmap(img, 20, 20) simg.Save("target20x20.png") End Using End Using Edit: I think what I want is SuperSampling, like what Paint.NET does when set to "Best Quality"

  • Styling a list as tabs with a background overflowing into content

    - by Litso
    I couldn't think of any better way to name this question, but I'll explain. I have a mediawiki website with a background pattern (like parchment) behind the articles. At the top of each article I want to have tabs like wikipedia does (with page | talk | edit etc links). The problem is, the tabs should seamlessly fit with the article's background and I can't figure out if this is actually possible. The way I was trying to do it was positioning the list inside the actual content div and give the <li items a transparent background, but as far as I can see there's no way to color the rest of the <ul's background black without affecting the <li's in there. Anyone have an idea? (example url: http://dev.mansonwiki.com/wiki/Sandbox )

  • Network Block Device (NBD) clients for Windows or similar solutions

    - by przemoc
    Are there any NBD clients for Windows? Strangely, I cannot find any, or I am searching for them in a wrong way. Such client should be possibly a driver with front-end tool (may be a command-line one) allowing to create virtual drives and associate them with given hosts (or simply localhost) and ports where NBD servers are listening. From user perspective virtual drive should be close to what physical drive is, so it should be accessible as something like \\.\PhysicalDriveX (maybe \\.\VirtualDriveX?), be visible in Disk Management (diskmgmt.msc) and mountvol tools at least. (The only thing I found remotely close to NBD on Windows is ImDisk's proxy mode and companion tool devio, but AFAIK ImDisk only works at partition level (so no virtual drive) and devio uses different protocol.) Secondary question is: Are there any (preferably simple) Windows-specific solutions allowing creation of virtual drive delegating read/write request to user-space via some explicit way (like via TCP, IPC, DLL implementing given API, etc.)?

  • email tracking image duplicate requests

    - by DEH
    I am embedding tracking images within emails that are being sent from a custom-built opt-in CRM system. The image src is an encoded .gif, such as src="12_34_675.gif". The image is served by an ASP.NET httphandler that decodes the src encoding and serves a transparent image. Everything works fine, but some email clients request the image multiple times, creating duplicate entries. Some clients make three calls all within one second, and some seem to make tens of calls over a day or so. Mostly email clients make single calls, but these few duplicates are very perplexing. I know I can code around them, but I'd really like to understand what's going on. I've checked the IIS log files, which show that the duplicate requests are coming from the client machines. I can't think what might be causing these duplicate http requests. Help!

  • Connect iPad to windows 7 VPN

    - by Linuz
    My iPad keeps spitting out the error: "A connection could not be established to the PPP server." I am trying to connect it to a VPN I set up with Windows 7 as an incoming connection. On the iPad, I went into the VPN settings, added a new PPTP VPN with the following information Server: Windows 7 Computer's IP RSA SecurID: OFF Account: Account Username Password: Account Password Encryption Level: Auto Send All Traffic: ON Proxy: Off Now I know that it is making some connection to the Windows 7 Computer because whenever I intentionally put in the wrong VPN password on the iPad, it makes me put in the correct one before trying to connect again. All the ports are forwarded on my router for PPTP, and my Windows 7 Firewall is even off to try to get this to work. Any help would be greatly appreciated, thanks.
