• Sudo Non-Password access to /sys/power/state

  - by John

  On my computer, pm-hibernate appears to be broken, however using the command echo disk > /sys/power/state appears to work perfectly. Now I just need regular user access to it, using sudo. How do I do this? The command sudo echo disk > /sys/power/state simply returns bash: /sys/power/state: Permission denied. Also, I need this in a regularly used script, how can I make it so that I don't have to type in my password for it to work???

• Sharing samba-folder with root access

  - by Industrial

  Hi everyone, I have a staging server in my network running Ubuntu server 10.10, being my main development area. As I need to access the files in the Apache root from other computers in the network, I have setup samba with the following settings: [www] comment = Apache root www path = /var/www writable = yes force user = root force group = root On the host computer, running Ubuntu 10.10 desktop, I am trying to mount the drive with a bash file looking like below: #!/bin/bash sudo mount -t cifs //192.168.1.5/www /media/www/ -o username=myusername,password=mypassword,rw,iocharset=utf8,file_mode=0777,dir_mode=0777 What happens is that I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) thrown in my face whilst trying to execute the mount. I've done exactly the same, with exactly the same smb.conf & mount-bash file on another computer in my network, but this just wont work. What am I doing wrong? I am running out of ideas.

• "Can't open display" even after access with xhost

  - by Yann

  I'm trying to run a graphical program remotely, without using ssh. I've set the display variable on the server (let's say server.com, Linux, not ubuntu, and no su rights) to point to my workstation (workstation.com, ubuntu 10.04) setenv DISPLAY workstation.com:0 Then on my workstation I've tried both xhost +server.com and xhost + Then I ssh into the server (to test things): ssh [email protected] and try to run xclock, and get the following error: Error: Can't open display: workstation.com:0 I've looked at /etc/ssh/ssh_config on the workstation and I should be forwarding correctly: X11Forwarding yes. How do I go about troubleshooting this? What logs on the workstation document these failed attempts? To explain why I'm doing this: I want to run a batch job on a server to debug an MPI-based parallel program. I want to run xterm as the batch job executable, per the instructions provided by the system admins. This setup use to work. I reinstalled things on my workstation and since then I frequently get one-time message along the lines The authenticity of host 'hostname (XXX.XXX.XXX.XX)' can't be established. My attempt to fix the above was to move my ~/.ssh/known_hosts file to a back up on both server and host, and then to ssh from each to the other with the flag -o StrictHostKeyChecking=no. I no longer get that message, but I was wondering does this play a part in why X11 forwarding is not working?

• how to add programs to ubuntu without internet access

  - by captainandcoke

  I don't have internet access at my home and it takes me about a half hour to ride my bike to the library. I have downloaded .deb files to try to install at my home computer but everyone I have downloaded says it can't install because it depends on package X. The next day I will download package X and it will require package Y. Is there anyway to find out what ALL the sub-dependencies are for deb files? I have tried to boot from USB or External Hard drive on the library computers but the security settings prevent this. Also, I do not know anyone with a Linux computer.

• Installing Ruby on Rails without access to command line

  - by Darwin

  I'm VERY new to this whole web dev thing but I can program and I liked Ruby when I used it before. Now, I've got web hosting and a domain and a site on there that's currently ran under Joomla but I'd like to experiment with Rails. The most access I can get to the server is FTP and maybe a setting here and there in the control panel. Definitely no command line. Is there a way to just, I don't know, upload ruby on rails to a folder and run it in a browser? That's how Joomla works I think. Literally every article I read about this starts with "you just do sudo get..." mumbo jumbo.

• Deleting a game object causing an access violation

  - by Balls

  I tried doing this but it cause an access violation. void GameObjectFactory::Update() { for( std::list<GameObject*>::iterator it=gameObjectList.begin() ..... (*it)->Update(); } void Bomb::Update() { if( time == 2.0f ) { gameObjectFactory->Remove( this ); } } void GameObjectFactory::Remove( ... ) { gameObjectList.remove( ... ); } My thoughts would be to mark the object to be dead then let the factory handle it the on next frame for deletion. Is it the best and fastest way? What do you think?

• Outlook Calendar Attachments to have limited access to just Required attendees

  - by Jason Pearce

  The management team at my company often attaches documents (Word, Excel, PDFs) to their Outlook Calendar meeting requests. The meeting requests are sent to the managers, but also to their assistants. The desire is to have everyone be able to view the full meeting request and its content, but limit the ability to open the attachments to just the managers. Is there a way in Outlook 2003 and/or 2007 to limit access to attachments that accompany meeting requests? Ideally, can access to the attachments be controlled by the "Select Attendees and Resources" window when selecting individuals from the Global Address List. Can those in the Required field have access to the attachments while those in the Optional or Resources fields not have access? My suggestion was to simply place all meeting attachments in a shared network folder that has read/write access limited to managers. They would then just place fully qualified links to those files in the body of the Meeting Request. While everyone would receive and see the links, only a few would have access. This, however, wasn't easy enough for them, so I'm looking for some other ideas.

• SSH access failure from Ubuntu 12.04 LTS VM

  - by begueradj

  I installed 2 VMs on VirtualBox. VM 1: Windows XP with FreeSSHd and PuTTY installed.IP address: 10.0.0.2 VM 2: Ubuntu 12.04 LTS Server Edition with OpenSSH installed.IP address: 10.0.0.3 From VM 1, I run PuTTY with the IP address of VM 2 (10.0.0.3) and port number 22. I get prompted to input the username and password of VM 2 and everything works fine.From VM 2, I run on the terminal (Ubuntu): ssh [email protected] , I get prompted to enter the password of VM 1. I do so, but it says my password is invalid (while it is the correct one). I even deactived the Firewall on VM 1, but still the problem is here: my password is not accepted from VM 2. Is this due to some settings maybe I must do on VM 1 (Windows XP) so as I can access it with SSH ? Maybe it has something to do with the Firewall of Windows XP ?Important information: ping 10.0.0.2 from VM 1 and ping 10.0.0.3 from VM 2 are working successfully.

• How to access a Windows share from Ubuntu?

  - by Cyberscooty

  In Ubuntu 12.04 and previous versions, I can easily install smbfs and running smb://server/share from Nautilus works! But, in 12.10, I can't install smbfs. Trying to install it from the terminal, I see this that the package is obsolete: Reading package lists... Done Building dependency tree Reading state information... Done Package smbfs is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: cifs-utils E: Package 'smbfs' has no installation candidate How can access my Windows share easily in 12.10?

• ddwrt client brigde acces point lost

  - by llazzaro

  Ok I have an AP with ddwrt firm (i know its not the best, but continue reading!) AP is configured to work like a wifi "transparent" brigde, also it had a virtual wifi network card to expand radius of wifi signal in that same AP. The brigde is working, computers behind AP gets ips from main routers which shares internet....BUT! I cant access webgui of the bridge AP... Main problem : AP is lost, but its working as brigde. I cant find it in the network (it didnt have any ip!) so I cant change any configuration... First solution : Reset AP, but it cannot be done. Reset button dont works due to a bug in ddwrt micro firm that mi linksys WAP54g had installed (I really hate this firmware I like more openwrt that my main router has) Second Solution : arp -a from main router , from computers behind AP...It dont appears in the list. Any more ideas, the router at some level must be there, the brigde is working. I know its possible that the AP is with an ip like 192.168.100.2 , my subnect actually is 172.16.X.X. :) thanks!

• Need to setup and access web disk for a hosting account

  - by mtk

  I am on linux(ubuntu 12.04) and have purchased a hosting space. In the cpanel, I selected nautilus for accessing web-disk and I was given a note: Note: In order for the Web Disk to work, you will need to allow port 2078 (SSL) or 2077 (non-SSL) on your computer's firewall. As, I am unable to connect to this, i.e. on entering the given url in Nautilus address bar, it says 'Connection closed'. So, I believe the above this quoted is not correctly configured. Please let me know, how to configure this? How to allow the given port access?

• access to site owner not working

  - by Daveo

  I made a website it works for everyone except for the site owner, who cannot access the site. He gets a server could not be found error. I went to his house and the issue occurs for all of his devices (PC, laptop, iPhone using WiFi) when I turn WiFi off the iPhone it works. So I thought it was a problem on his router so I reset is router to default factory settings but it still does not work, I have flushed his DNS cache and his browser cache. But nothing seems to help. He cannot even PING the server using the domain name. However when he uses the IP address he can see the site fine. I looked in cpanel for an blocked IP addresses but cannot see anything. What could be stopping just him from accessing the site via domainname and not the IP address? Site details are: PHP, osCommerce it is hosted by site5 on my reseller account.

• Storing large array of tiles, but allowing easy access to data

  - by Cyral

  I've been thinking about this for a while. I have a 2D tile bases platformer in XNA with a large array of tile data, I've been running into memory problems with large maps. (I will add chunks soon!) Currently, Each tile contains an Item along with other properties like how its rotated, if it has forground / background, etc. An Item is static and has properties like the name, tooltip, type of item, how much light it emits, the collision it does to player, etc. Examples: public class Item { public static List<Item> Items; public Collision blockCollisionType; public string nameOfItem; public bool someOtherVariable,etc,etc public static Item Air public static Item Stone; public static Item Dirt; static Item() { Items = new List<Item>() { (Stone = new Item() { nameOfItem = "Stone", blockCollisionType = Collision.Solid, }), (Air = new Item() { nameOfItem = "Air", blockCollisionType = Collision.Passable, }), }; } } Would be an Item, The array of Tiles would contain a Tile for each point, public class Tile { public Item item; //What type it is public bool onBackground; public int someOtherVariables,etc,etc } Now, Most would probably use an enum, or a form of ID to identify blocks. Well my system is really nice just to find out about an item. I can simply do tiles[x,y].item.Name To get the name for example. I realized my Item property of the tile is over 1000 Bytes! Wow! What I'm looking for is a way to use an ID (Int or byte depending on how many items) instead of an Item but still have a method for retreiving data about the type of item a tile contains.

• URL subfolder rewrite without server access

  - by Duke03

  I am having trouble with the following. I have a site in development that has every link on the site pointing to the wrong folder. Example: example.com/en/home/, a site link goes to example.com/en/, which throws a 404. Now the way the system is setup requires server access but I do not have that and I/S is backlogged with requests and will take a week. But I still need to develop the site. So is there a way to have the browser recognize when example.com/en/ is clicked then automatically redirect it to example.com/en/home so it bypasses the 404 and I can actually work. Im looking for anything that gets the job done. I am considering developing a Chrome app to do this but that would mean a shit ton of overtime and more work I don't want to do. Is there a easier way of doing this?

• Can't access computer

  - by Pudica

  I'm running Ubuntu 14.04 on an Intel NUC and it won't boot! The last successful boot was earlier today but now each time I try it gets stuck on the Grub menu where it prompts for memory check etc. This is not a dual boot system, so this screen shouldn't ever appear, and it never has before. It's GRUB version 2.02~beta2-9, which is a little disconcerting, as I'm on the stable sources. Unfortunately the keyboard (I've tried 2 keyboards just in case) is not responding at this point in the boot process, so I can't select the "Ubuntu" menu option in Grub. The keyboard works during the bios stage, so I can configure it to boot from USB, and I tried a flash drive with 14.04 on it. The flash drive works in my laptop but is completely ignored by the NUC (I tried all 3 USB ports!). It seems that I have no way of getting into the machine at all! The Intel support site was my first option, but the site is down. I expect it's a long shot, but if anyone has any ideas I'd be very grateful.

• Need private personal access to ~three PHP pages

  - by Roger

  I would like secure access to the text output by three PHP scripts (the text output is JavaScript and html) . The security level is much less then financial data but important none-the-less. I have considered purchasing AND studying https and SSL certificates. Hostgator charges an extra $2/month for a private ip plus $50+ anually for a certificate. This is more then I want to spend for this project (time + money). Is there a simpler solution that is: less expensive easier to implement. I'm open to different approaches.

• Organizing your Data Access Layer

  - by nighthawk457

  I am using Entity Framework as my ORM in an ASP.Net application. I have my database already created so ended up generating the entity model from it. What is a good way to organize files/classes in the data access layer. My entity framework model is in a class library and I was planning on adding additional classes per Entity(i.e per database table) and putting all the queries related to those tables in their respective classes. I am not sure if this is a right approach and if it is then where do the queries requiring data from multiple tables go? Am I completely wrong in organizing my files based on entities/tables and should I organize them based on functional areas instead.

• How to access variables of uninitialized class?

  - by oringe

  So I've gone with a somewhat singleton approach to my game class: #include "myGame.h" int main () { myGame game; return game.Execute(); } But now I need to define a class that accesses variables in the instance of myGame. class MotionState { public: virtual void setWorldTransform (...) { VariableFromMyGameClass++; //<-- !? ...} }; I'm trying to integrate this class into my project from an example that just uses globals. How can I access variables of myGame class in the definition of new classes? Should I give up on my singleton approach?

• Revoke directory access for a particular user in Solaris

  - by permissiontomars

  I have a need to allow directory access to a particular user on my file system. I want this user to be unable to access any other directory in my file system (initially anyway. It may need access to some directories later). For example: I have a directory called /opt/mydir. - I want my dedicated user to only be able to access this directory, and nothing else. - I want all other users to be able to access this directory as normal. I'm new to Linux and its permissions. I've read a fair bit of background material but I'm a little confused. Is there anyway to revoke permissions to /opt/mydir for a single dedicated user? A possible flawed method would be to only allow access to /opt/mydir and exclude every other user. This won't work because I want all other users to work as normal; accessing the directory. I'm working on Solaris 10. Any suggestions are appreciated.

• How to setup complete file access and control on a network

  - by user96270

  I have a media server running ubuntu 12.04 and I want it setup so that any PC on the network (windows etc) has complete access to all files, folders etc with read, write, edit, copy to, copy from permissions. No need for security (IE no password or user name, just select it on the network and start editing). I have samba installed and personal file sharing is enabled but my windows PC cannot see it on the network. I already set up another server as I described but unfortunately I can't remember how or where I found the guides for it. Any on know of a guide that covers what I want?
