  • Will using Apache's ProxyPass directive on persistent Ajax connections alleviate the connection limit error?

    - by naurus
    I've got some javascript that keeps a persistent Ajax connection open for each client, and I know that this can cause some serious issues for apache, but not for lighttpd. One thing I learned from researching how to get around this was how to use the ProxyPass directive to send all requests for a certain directory to another address:port combination (without letting the user know). What I want to know is, if I put my PHP in a proxy'd (to lighttpd) directory and call that with javascript, will this still count against my apache connection limit? The reason I wonder is that apache is still serving the content, just not processing it. Seems to me that this would be a connection. Thanks

  • Blank white desktop icons on new Windows 7 install

    - by SiegeX
    I just did a fresh install of Windows 7 professional on my father's Toshiba Satellite laptop and everything went smoothly except for the fact that certain desktop shortcuts appear as a blank white page. I've tried: going in and changing the icon to many different things reloading the icon cache by deleting the IconCache.db file uninstalling his Free AVG as he heard the virus scanner might be preventing it (it wasn't and he put it back.) The one thing these icons have in common is that they are shortcuts to some very old DOS executables. One of them is Word Star 2000 to give you an idea. Does anybody have any other suggestions besides what we've tried?

  • port forwarding on windows server 2008 to Hyper-v machines

    - by This is it
    I have a host machine (win server 2008 R2) with several Hyper-V virtual machines. I want to be able to redirect certain ports of host to virtual machines. There is virtual network connection between host and virtual machines (192.168.10.xxx). Host is also attached to external network (10.10.10.123). Virtual machines have several other networks between them. E.g., I want to be able to redirect traffic from 10.10.10.123 12345 to 192.168.10.321 54321 I tried RRAS in windows server but for it to work Default gateway to 10.10.10.123 has to be set in virtual machines. Virtual machines can not be on external network.

  • Can you disable UNC paths in Windows?

    - by Evan
    We are trying to lock down a Terminal Server, and want to remove a commercial package's ability to accept UNC file paths, ie. paths in the app can then only be entered using the windows drive letters. Is there any way to do this in Windows? Can we disallow UNC paths for just the app? Can we disallow UNC paths for the entire Terminal Server session? The intention is to allow the application to only write to certain directories (as mapped in the Terminal Server session). The aim is to prevent the output of files to directories that the users have access to, but are not mapped in the Terminal Server session.

  • Associating multiple data with a single entry in Open Office Base

    - by idyllhands
    I'm trying to build a database that I can use to track prices of groceries on certain dates. My problem is that I cannot figure out how to have a single entry associate with multiple data. For example, carrots. The index would be carrots. Then, a few categorizing fields (ie, Produce|Vegetable) Then, I can enter a price, date that the price was valid, store that was selling for said price, etc. And the next time I buy carrots, I can just add a new set of pricing data that would be associated with the original carrots entry. I know very little about database building, so if anyone has something I could just modify, I would greatly appreciate it. Alternatively, a step by step tutorial would be great.

  • What influences the kind of RAM a desktop or laptop can support?

    - by Albert Iordache
    What exactly influences the kind of RAM a desktop or laptop can support? Apart from the clock speed, the maximum amount of RAM the motherboard can handle, the DDR type (1/2/3) and the shape of the module (DIMM for desktops, SO-DIMM for laptops)? I see that in certain cases, such as with the Kingston 4GB DDR3 1333MHz CL9, (and on the Kingston KTD-L3B/4G page) the page displays a set of laptop product numbers. Does the actual model of the laptop also influence the models of RAM it can support? Could, for instance, an Asus K52 work with that particular RAM module, even if it specifies Dell models?

  • forward all mail on a specified domain to script

    - by David
    Hey all! I run a disposable e-mail service that accepts all incoming mail and forwards it to a PHP script that stores it in a database for people to view. Before now, I have been on shared hosting with cPanel, which makes it easy to pipe e-mails to a script. Now, however, I got my own VPS, and it doesn't have cPanel. How do I pipe e-mails to script? Further, how do I pipe emails to any address on certain specified domains to my script? You see, aside from the main domain, there are several alternate domains that people can use if the main domain is blocked, and on each domain I want any address to be usable (xyz@domain, abc@domain, anythingelse@domain). The VPS has Ubuntu 9.04 installed, and I have been experimenting with Postfix, though I can switch to Exim or Sendmail if it is easier.

  • Synchronize pasteboard between remote tmux session and local Mac OS pasteboard

    - by bhargav
    Setup: I use iTerm2 on MacOS to connect to a remote server. The remote server runs tmux, in which I open files and edit in vim sessions. Problem: I can't copy/paste between the remote tmux session and the local iTerm client. I can use iTerm 2's alt/option + mouse selection to select text, but this copies over multiple vim panes/tmux panes - bad. Is there any elegant solution to make selections in tmux panes synchronize between the remote pasteboard and the local (MacOS pasteboard)? I've seen reattach-to-user-namespace, but I'm pretty certain it doesn't do what I want.

  • ssh through a bastion machine works on someone else's desktop but not my own

    - by Terrence Brannon
    I have to ssh into a bastion (jump) server in order to get to the final server. On the jump server, my .ssh/config says: Host * ForwardAgent yes My co-worker uses PuTTy and Pageant. When I use a putty shell to connect from his desktop to the final server as root via the jump server, it works fine. At my desk I cannot connect to the final server, only the jump server. However, if I go to his desk, and successfully log into the final server via the jump server, I can then go back to my desk and also do so.... but after a certain amount of time, my shells revert to the original behavior of not connecting to final server via jump server. The entire transcript of ssh -v -v -v final_server is here The relevant part to me is when the public key is offered but then it says 'we did not send a packet': debug1: Offering public key: /home/CORP/t.brannon/.ssh/id_dsa debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password debug2: we did not send a packet, disable method debug3: authmethod_lookup password

  • Setup VLAN agnostic ports on HP ProCurve 1810G (Ingress Filter, Trunking)

    - by Thomas
    I am wondering if it is possible to configure some ports of the web managed ProCurve Switch 1810G to participate in all VLAN traffic. Even if no VLAN with that ID has been set up inside the switch. The issue is that I have two virtualization servers that will use yet unknown VLANs of a certain range to communicate with each other. But the range is much larger than the 64 supported VLANs this switch can manage. The switch also offers static and LACP Link Trunks. But I guess there will also apply the Ingress Filter that drops packets with unconfigured VLAN IDs? A separate unmanaged switch that connects the two hosts and one ProCurve Port would work, but maybe I do not have to? Thanks

  • Using an allowed user list with VSFTPD

    - by Naftuli Tzvi Kay
    According to the Wiki here, you can only allow certain users to log in over FTP using the following configuration in your /etc/vsftp.conf file: userlist_enable=YES userlist_file=/etc/vsftp.user_list userlist_deny=NO I've configured my system to use this configuration, and I only have one user which I'd like to expose over FTP named streams, so my /etc/vsftp.user_list looks like this: streams Interestingly enough, I cannot log in once I enable to user list. If I change userlist_enable to NO, then things work properly, but if I enable it, I can't log in all, it just keeps trying to reconnect. I don't get a login failed message, it just keeps trying to reconnect when using lftp. My /etc/vsftp.conf file is available on Pastebin here and my /etc/vsftp.user_list is available here. What am I doing wrong here? I'd just like to only make the streams user able to log in.

  • Autoscale Rackspace Cloud, Scalr or DIY?

    - by Andre Jay Marcelo-Tanner
    I'm looking into creating a setup on Rackspace Cloud that will allow me to autoscale my webservers (no db) on demand. Preferably using something like response time. I've read into configuration tools like Puppet/Chef, but I'm thinking I can just launch from prepared server images that are ready to go. Is there any tool out there already that can monitor my existing node response times and then launch or scale up new ones based upon certain variables like average X load over Y time? I see there are commercial offerings like Scalr, Rightscale, but how would I do this myself?

  • Using DNS in iproute2

    - by Oliver
    In my setup I can redirect the default gateway based on the source address. Let's say a user is connected through tun0 (10.2.0.0/16) is redirect to another vpn. That works fine! ip rule add from 10.2.0.10 lookup vpn1 In a second rule I redirect the default gateway to another gateway if the user access a certain ip adress: ip rule add from 10.2.0.10 to 94.142.154.71 lookup vpn2 If I access the page on 94.142.154.71 (myip.is) the user is correctly routed and I can see the ip of the second vpn. On any other pages the ip address of vpn1 is shown. But how do I tell iproute2 that all request at e. g. google.com should be redirected through vpn2?

  • Getting apache to use ldap group and filesystem group information

    - by Angelo
    We have an Apache server which serves out of a particular directory, and just supplies a listing of files. From this directory, each subdirectory is owned by a certain group of users (at the filesystem level). User groups are determined by a posixGroup in ldap. Is there any simple way I can tell Apache to authorize access based on filesystem permissions, just like if the users were to access the filesystem from a shell? I would like to be able to simply add users/groups/directories without having to add another Directory or Location directive in Apache's conf?

  • Outlook folder structure Template

    - by Filip Ekberg
    Having a lot of different customers and a lot of different areas to work with makes it trivial to have your mail folders in order. Everytime I get a new Project / Customer I want to add a certain Folder Structure in my "Customer" / "Project" sub directory. It might look like this: Customer_name/ Bugs Documents Important Support/ Done And as it is today, I have to manually add these manually, which is harsh when you have a lot of it going on and each sub directory under the customer_name directory needs to have "display all items" since it's important to me to see all Items in Bugs / Support / Important. Makes my life easier. So, Is it possible to Automize the process somehow? Macro? Folder Templates? What are my options?

  • Issue with IIS...SERVER APPLICATION UNAVAILABLE

    - by SVI
    My web application was running absolutely fine. Just 2 days back, I got an error saying. SERVER APPLICATION UNAVAILABLE I am pretty certain that nothing was changed on IIS. Unless my automatic Windows updates screwed it up completely. My event viewer had zillions of following errors in Application category. aspnet_wp.exe could not be started. The error code for the failure is C0000005. This error can be caused when the worker process account has insufficient rights to read the .NET Framework files. Please ensure that the .NET Framework is correctly installed and that the ACLs on the installation directory allow access to the configured account. I reinstalled IIS. After installing, i ran aspnet_regiis -i for framework v2 and now it throws error saying - The application could not be initialized properly. Any ideas what going on?

  • Windows 2008R2 blocks outbound LDAP for non-admins?

    - by Jon Bailey
    I've got a Windows 2008R2 terminal server with ~30 users on it. It's joined to a Samba-based domain. During the login script, we connect directly to the LDAP server to pull out certain profile information. This used to work just fine. Now, it doesn't, but only for non-local-admin accounts. Local admins work fine. As a non-local-admin: Connection to ports 389 or 636 just terminate (wireshark on the LDAP server reveals no connection attempt) Connection to other ports on the same server work fine Same thing on multiple LDAP servers Windows firewall is disabled Can't find any other rules/policies that may block this I suspect since this used to work, it came down during an update, but for the life of me, I can't find what. EDIT: I just ran Wireshark on the machine and didn't see anything when connecting to the LDAP server in question (or any LDAP server for that matter). I can, however, see traffic when I connect to that server on another port.

  • Scratched DVD keeps freezin when copying files, even with programs.

    - by Murtez
    Hi, I have a dvd with some family photos that is scratched, the problem is that when i try to copy stuff it reaches certain points and freezes, i'm assuming its the scratches / corrupt data. I've been trying several programs that are supposed to copy corrupt files from damaged media regardless, but they keep freezing when they reach the same points, so no different when with windows. Is there a way to fix the DVD? Or a really really good program that can do that without freezing / allowing windows to freeze? Please help, I don't have any copies of the photos and they are irreplaceable.

  • Using terminal vs KDE in linux?

    - by Ke
    Hi Im used to using nautilus within centos but have recently just got a VPS and quickly realising that using a KDE is unacceptable in this environment. Although I do find it so much quicker doing things like folder permissions in KDE rather than typing it all out in the terminal? Everyone I speak to says, use the terminal and I should learn this way as opposed to using the KDE, but theres certain things I just dont get How is it possible to make quick changes to scripts and viewing them in a browser etc , without a mouse or using KDE? and only using a terminal?? I am wondering how to develop websites just using the terminal??? How can it be quicker to type out/view permissions etc in the terminal when its instant and just a few clicks in the KDE? Any thoughts are much appreciated. I would love to understand the benefits but just cant seem to see them right now. Cheers Ke.

  • .htaccess to deny access to most xml files

    - by CEich
    I recently had a Joomla site hacked, so I'm trying to harden the site a bit. There's a section in the recommended .htaccess that restricts outside access to the xml files that come with extensions. However, it also keeps my sitemap.xml file from being accessed. How do I allow a certain file whiles keeping the rest? here's the default code: <Files ~ "\.xml$"> Order allow,deny Deny from all Satisfy all </Files> and my modification that caused a 500 error: <Files ~ "(?!sitemap)\.xml$"> Order allow,deny Deny from all Satisfy all </Files>

  • VSFTPD Unable to set write permissions on folder

    - by Frank Astin
    I've just set up my first FTP server with VSFTPD on cent os . I can connect to it fine using a user in the group ftp-users but I get read only access . I've tried several different CHMOD codes on the folder (even 777) all to no avail . This is the tutorial I used to set up the server http://tinyurl.com/73pyuxz hopefully you'll be able to see something I missed. Thanks in advance .

  • PostgreSQL automatic backup

    - by Ragnar123
    I have been trying to set up a backup script on a windows server. I have used pgAgent (scheduling for pgAdmin), to run the backup script. No problems with the backup script. However, my jobs are not running like they should. I have set both the schedule, and the steps. I am fairly certain, that I am running the service under a wrong user or a user without the required permissions. I run the service like this: "C:\Program Files\pgAdmin III\pgAgent" INSTALL pgAgent -u postgres -p secret hostaddr=127.0.0.1 dbname=pgadmin user=postgres And I get an error, telling me that there was an error with the login information, though I know it's correct. When I go under services (controlpanel -- administration -- services), I am able to start the service with the local user. Can this be the problem? Where can I see or change the permissions on the postgres user?

  • Looking for Inneroffice Access Tool, Workstation to Workstation

    - by nicorellius
    This may be a simple question to answer, and I apologize if it's a duplicate. I looked through the suggestions and nothing jumped out at me as the right answer, so here goes: My office has several workstations, Macs and Windows boxes. We do have a firewall and a VPN solution, so getting in to the network from outside is easy. Likewise, we use GoToMeeting for demos and when we help our customers with their issues. But we have one workstation that has certain testing tools on it, and instead of walking across the office to this machine, I'd like to access it from my desk (and monitor it). I will need to open a command line and run commands. I could start a GoToMeeting and do it this way, but that seems overkill and clunky. Is there a simpler tool that allows pseudo-remote access within the same office/network for this kind of access?

  • Create a Windows Image for Deployment

    - by Kiranu
    In my company we have 8 laptops that we use to deploy on the field. These machines get assigned to a user for a certain time and run Windows Vista. All the machines are the same model. After the machine is returned, it is company policy to completely format the machine and go back to a predetermined configuration. Right now, what we do is we use the recovery utility in the laptop (we are a small shop so we use the OEM Windows license that the laptops come with) and manually uninstall and change the configuration in order to bring it to our baseline config. I know that there are ways to create an image that gets copied to the hard drive with a specific configuration and with specific software installed (thats what OEMs do right?). I'm looking for a tool or a tutorial or something that explains as simply as possible how to create such an image. Thanks a lot

  • AutoCAD 11 and network file shares

    - by gravyface
    Small network of perhaps half a dozen engineers, currently working on local copies of AutoCAD project files, which are then copied back up to file server (2008 Standard, 1-2 year old Dell server hardware, RAID 5 SAS disks (10k? not positive)) at end of day. To me, this sounds horribly inefficient and error-prone, however, I've been told that "AutoCAD and network files = bad idea" and this is gospel. The network is currently 10/100 (perhaps this is the reason for the "gospel") but all the workstations are within 2 years old and have GbE NICs so an upgrade of the core switch is long overdue. However, I know certain applications don't like network access, at all, and any sign of latency or disruption brings the whole thing crashing down. Anyone care to chime in?
