• Finding users near other user

  - by Bunny Rabbit

  what algorithms should I explore to implement a feature which lets a user find other user located near him , the latitude and the longitudes of all the user are known in advance and are fixed [not dynamic]. Also i believe that there should be a better way to store such data then simply storing the lat , long of the user against his user id in a database.What are the efficient ways to handle this ?

• how to extract all permissions that a domain user have on the network

  - by Alexandre Jobin

  I would like to know all the permissions a windows domain user have in my network. Is there a way, with a script file or a tool, that can extract this kind of information by checking all the servers and computers in my network? I'm on a Microsoft network with Windows Server 2008 R2, Windows XP, Windows 7. The report should include these kind of informations: report all permissions that the domain user have (read, write, etc...) if the domain user is in a domain group, tell me the permissions that this group have in my network so the report could be something like this: Permissions for USER_A in the DOMAIN.COM the user is part of theses domain groups: GROUP_A GROUP_B SERVER_A W:\wwwRoot (R/W inherited from GROUP_A) W:\sharedFolder (R) SERVER_B c:\projects (R/W) c:\projects\project_a (R/W) c:\projects\project_b (R/W) c:\dumpfolder (R/W inherited from GROUP_B) COMPUTER_A LOCAL\Administrator c:\ (R/W)

• Creating Limited User Accounts on Ubuntu Server

  - by LonnieBest

  Using Ubuntu server, I need to create some user accounts that have the following limitations: (1) User may only view and manipulate files in their home directory. (2) User may only execute commands related to rsync and sftp. I want users to be able to backup files using rsync, and I want them to be able retrieve files using an sftp client like FileZilla. Other than this, I don't want users to be able to view other files on the system, or execute any commands that might mess with the system. I'm more of an Ubuntu Desktop user, and have very little experience administering a linux server. Most tutorials I've found assume I know things that I don't know. So I'm having difficulty setting this up.

• Active Directory, Linux, and User Private Groups

  - by larsks

  We're in the process of moving from NIS on our Linux systems to binding everything to Active Directory. The NIS environment follows the common standard used by many Linux distributions that a user's primary group is a group of the same name as the user (and of which the user is typically the only member). I have been informed that in the Active Directory environment, you may not have a group name with the same name as a user (specifically, that no two AD security objects may have the same name). This would seem to complicate the process of moving our group definitions into AD. It looks like we could maintain the NIS group information in AD using only POSIX attributes (e.g., not an actual AD security object), but that seems like a suboptimal fix (because we do really want to have the same view of group membership in both the Unix and AD worlds). Have you moved a large legacy NIS environment into Active Directory? How did you handle this situation?

• OpenSSH SFTP server with chroot() + user with chroot exception

  - by HannesFostie

  I am currently setting up an SFTP server but there is one detail I can't seem to figure out. When I add a user, I would like him to connect using his client and be able to write in his "root dir" right away. My Match case for the SFTP-users group currently has ChrootDirectory set as "/home/%u", and inside that directory I have to have a subdirectory owned by the user, while /home/%u itself is owned by root. Next to that, the "root dir" also has a couple files, .bashrc to name one. Is it possible to put these files somewhere else, remove them, or at least make them invisible to the user? Thanks EDIT: One more little thing I'd like to implement is for one account to have read (or rw, not sure yet) access to all other users' home directories. What is the easiest way to implement this? EDIT 2: Basically, having one user be an exception to the chroot rule would get me started.

• Set up FTP user with ProFTPD on Ubuntu

  - by kidrobot

  I want to set up a user "ftp" so they can upload and download files in my /home/httpd/mysite/public_html directory. All files in public_html are owned by user ftp and in group www-data so the ftp user looks like so: uid=108(ftp) gid=33(www-data) groups=33(www-data),65534(nogroup) When I try to connect via an FTP client I get 530 Login incorrect. ftp: Login failed. What do I need to uncomment/add to the proftpd.conf file to make this work?

• Why do weekly tasks created via PowerShell using a different user fail with error 0x41306

  - by Danny Tuppeny

  We have some scripts that create scheduled jobs using PowerShell as part of our application. When testing them recently, I noticed that some of them always failed immediately, and no output is ever produced (they don't even appear in the Get-Job list). After many days of tweaking, we've managed to isolate it to any jobs that are set to run weekly. Below is a script that creates two jobs that do exactly the same thing. When we run this on our domain, and provide credentials of a domain user, then force both jobs to run in the Task Scheduler GUI (right-click - Run), the daily one runs fine (0x0 result) and the weekly one fails (0x41306). Note: If I don't provide the -Credential param, both jobs work fine. The jobs only fail if the task is both weekly, and running as this domain user. I can't find information on why this is happening, nor think of any reason it would behave differently for weekly jobs. The "History£ tab in the Task Scheduler has almost no useful information, just "Task stopping due to user request" and "Task terminated", both of which have no useful info: Task Scheduler terminated "{eabba479-f8fc-4f0e-bf5e-053dfbfe9f62}" instance of the "\Microsoft\Windows\PowerShell\ScheduledJobs\Test1" task. Task Scheduler stopped instance "{eabba479-f8fc-4f0e-bf5e-053dfbfe9f62}" of task "\Microsoft\Windows\PowerShell\ScheduledJobs\Test1" as request by user "MyDomain\SomeUser" . What's up with this? Why do weekly tasks run differently, and how can I diganose this issue? This is PowerShell v3 on Windows Server 2008 R2. I've been unable to reproduce this locally, but I don't have a user set up in the same way as the one in our production domain (I'm working on this, but I wanted to post this ASAP in the hope someone knows what's happening!). Import-Module PSScheduledJob $Action = { "Executing job!" } $cred = Get-Credential "MyDomain\SomeUser" # Remove previous versions (to allow re-running this script) Get-ScheduledJob Test1 | Unregister-ScheduledJob Get-ScheduledJob Test2 | Unregister-ScheduledJob # Create two identical jobs, with different triggers Register-ScheduledJob "Test1" -ScriptBlock $Action -Credential $cred -Trigger (New-JobTrigger -Weekly -At 1:25am -DaysOfWeek Sunday) Register-ScheduledJob "Test2" -ScriptBlock $Action -Credential $cred -Trigger (New-JobTrigger -Daily -At 1:25am)

• Postfix - How to alias some [email protected] to another user, but only for certain values of "host.com"

  - by Rory McCann

  I have a Postfix email setup. It's handle a few domains (i.e. I have them in my mynetworks in my main.cf). I have a normal unix account and use that to log in, and get my mail. My personal email account is of the form [email protected]. I have a new domain new.com, and I want to forward [email protected] to [email protected], however I don't want to forward [email protected]. Someone has suggested just forwarding all 'info' to 'user', and then using procmail on my user@ account to remove the [email protected] The server is Ubuntu.

• copSHH how to restrict user from going back from there main root

  - by minus4

  I have installed SFTP on a windows servers using copSSH and all is good and it works well however you can go back from the main root. For example when i use C:\copSSH\home{username} as that user i can go back into copSSH and into them directories too. And I have a user setup to actually be C:\inetpub\wwwroot but that user can go into the system and everything i have this set as my path /cygdrive/c/inetpub/wwwroot It would be ideal if the user could only go forward from the start directory, rather than out and about there is no write ability but there is read and download....... thanks

• Create a new Plesk CLI user

  - by mattdwen

  I am trying to create a user which has rights to the Panels (v11) CLI tools. I've added the user to the psaadm group, as the documentation indicates, as well as the swkey-data group, as I was getting access denied for that dir. I am using sudo to run the command as that user: sudo -u mcp /usr/local/psa/bin/subscription --info test.com But I am receiving this error: Unable to connect to database: get_admin_password() failed: file_get_contents() failed: Suggestions?

• Large Users Profile - Windows 7 - Machine running slowly

  - by Richard

  I have the MD of a client of ours who has a Windows 7 Profile that is currently 14GB thanks to Videos/Music and Documents. The first thing we did was to switch from roaming to local. What I need to know is now the profile is local am I wasting my time by reducing it any further? Does it really make a difference to performance having a large local user profile? Only the 4GB outlook ost that talks to the network frequently. Thanks in advance.... Richard

• Consequences of changing a password in Windows

  - by Borek

  I'm having 2 machines on my home network where I have the same account name but different passwords. I believe there should be advantages to having a single one (I hope :) but also think that changing it on one of the machines will do something - I'm just not sure what exactly. Will my stored passwords in IE and Chrome still work? Scheduled tasks? Etc. I'm looking for a list of things that I should watch out for after I change the user password.

• None of my bash commands work

  - by Kevin

  I have an Ubuntu 9.10 netbook. I has always run great. Two days ago, I was running as root for a while (~30), and when I moved back to my user account (only other account one this machine), all the commands in ~/bin stopped working. If I try ls, it comes up with "cannot execute binary file". Same with ln, mv, mkdir, clear, cp, etc. They all run as root(which makes sense, different files), but I have no idea why this happened. I don't want to stay as root to move around easily. Any idea?

• how to limit disk space per user in a PHP web application & CentOS

  - by solid

  we have a web application written in PHP and we want all our users to be able to upload images for e.g. 50MB. We will create a directory structure so that every user has its own folder like app/user1/images app/user2/images ... Now everytime a user uploads an image, we need to check if this is still allowed or not but we don't want 1000 users to continously scan our hard drive counting file sizes in their directory. So writing a script that counts all file sizes in a user directory is not an option I guess? Is there an easier way to calculate used up space per user and limit our app accordingly?

• Mod_security questions and on User-Agent types

  - by Tiffany Walker

  Very new to mod_sec I want to block a UA string and I noticed there are a few types: SecRule HTTP_User-Agent SecRule REQUEST_HEADERS:User-Agent What is the real difference between them? My block: SecRule REQUEST_HEADERS:User-Agent "perl" "phase:2,pass,msg:'Perl based user agent identified'" Do I need to set a SecDefaultAction phase:2,deny,status:403,log,auditlog before that? Then any SecRule below that follows that action right?

• User directive in nginx generates error despite running as UID root

  - by Joost Schuur

  I'm running nginx on a MacOS X machine, installed with brew, and when I launch nginx, even with sudo, I get the following warning in my log file over and over again: 4/21/11 2:03:42 AM org.nginx[3788] nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /usr/local/etc/nginx/conf/nginx.conf:2 From nginx.conf: user jschuur staff; I'm already launching nginx with sudo, since I want the thing to listen on port 80. Shouldn't that be enough to give it the proper super user privileges? The nginx binary as it's installed: jschuur@Glenna:sbin ? master ls -la total 4544 drwxr-xr-x 3 jschuur staff 102 Apr 12 20:53 . drwxrwxr-x 15 jschuur staff 510 Apr 12 15:25 .. -rwxr-xr-x 1 jschuur staff 2325648 Apr 12 20:39 nginx FWIW, I recompiled the binary to set passenger up and moved it around from it's original location into /usr/local/sbin. Update: As it turns out MacOS X was restarting nginx after I'd stopped it, because the launchd plist in ~/Library/LaunchAgents had set it to 'KeepAlive'. However, because I installed this plist into my local user's LaunchAgents folder as opposed to /Library/LaunchAgents (or better yet /Library/LaunchDaemons, which run before you even log on), it wasn't executed as root. Because of an error about not having permissions to use port 80, it actually exited right away, but still wrote to the same log file as the nginx process I started with sudo. I had thought the errors stemming from the automatic restart were actually coming from my manual restart via sudo. So, bottom line, problem solved. The real problem here was the homebrew instructions specifically asking you to install the plist file into an area that wouldn't allow a local site to use port 80.

• Login problems on SQL EXPRESS using a user

  - by meep

  Hello Serverfault. First time I set up a SQL server, so I hope you can help me out. I have a problem regarding logging in using SQL auth on my SQL EXPRESS 2008. I have added a user though the management interface as you can see on the image below. But as soon as I try to login using SQL auth I get an error the login failed for the user. The server log says: Login failed for user 'zebisgaard'. Reason: Could not find a login matching the name provided. [CLIENT: <named pipe>] Error: 18456, Severity: 14, State: 5. Do you have an idea why? I have triple checked that the username/password is correct, tried to recreate the user and so much more. And all this is localhost.

• Change desktop background at school

  - by Nano8Blazex

  On school computers, I can log in with a user account stored on the school network (something like that, I have no experience in networking and this sort of stuff). Everything is fine and dandy and totally works as it should, but there is one thing that I find annoying. Apparently for some reason I can't change my background to anything more than a couple of different solid colors with our school's logo still stuck in the middle. (the original background is a white logo on black background. If I change it to a different color, the central 6x6 inch black/white logo still remains, only the surrounding color is changed.) It may have been set by school administrators or something, I don't really know. I find this really ugly. Is there any way to change a setting so that I can set the background to any picture I wish? (like on a home pc...) Thanks.

• MySQL: "UPDATE command denied to user ''@'localhost'"

  - by Uncle Nerdicus

  For some reason when I installed MySQL on my machine (a Mac running OS X 10.9) the 'root' MySQL account got messed up and I don't have access to it, but I do have access to the standard MySQL account 'sean@localhost' which I use to log into phpMyAdmin. I am trying to reset the 'root' password by starting the mysqld daemon using the command mysqld --skip-grant-tables and then running the following lines in the mysql shell. mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass') -> WHERE User='root'; mysql> FLUSH PRIVILEGES; Problem is when I try to run that MySQL string the daemon spits back a ERROR 1142 (42000): UPDATE command denied to user ''@'localhost' for table 'user' as if I didn't use the -u argument when I started the mysql shell, either though I did. Any help is muchly appreciated as I am lost at this point. :/
