I am creating a new user for my son, but I don't want him to have access to M15+ games that are installed (eg Freedoom). Is there a way to deny a user's access to individual programs (or groups of programs). Also for the moment, I would really want him to only have access to a folder with his name on it and not to all of my drives and files on them. Is this possible? I couldn't find it anywhere...
View 9 RepliesIm trying to config my intranet to be accessible from inside the network (lan) without need of password and ask for a passwd for those who are viewing from Wan ....
Today my intranet can only be accessed from Lan, external access give me an Unauthorized message, I took look around, try #irc and still can get the appropriated help, I hope that someone here could help me on that...
A piece of my config:
Code:
What I need is, given a process id, list all his children without any clutter (table header, other columns than the pid) What I have is :
ps h --ppid $PID Which gives me:
26277 pts/13 S+ 0:10 cmd1
26280 pts/13 S+ 0:10 cmd2
Using h allow me to hide the table header. Is there a way to tell ps to not print the pts/13 S+ 0:10 cmd part in order to get a list of children process ids separated by carriage return?
Iv got an assignment to complete and I'm stuck at the basic level.
A part of the assigned problem is :
The main process will read the file, and will create N number of child processes (Where N is taken as input) as early as possible before all the children starts its execution. Before creation of each child, the main process should read the file to store all the required data in then corresponding data structure. Child processes should not read the file for getting their information.
As far as my knowledge about this , the child executes before the parent. How do I make the parent not pass the control to it's children before it finishes creating all the children?
I am currently programming a suite of daemons in c++ on CentOS 64. More or less all those daemons are SOAP servers, with the SOAP part handled by gSOAP.
One of the daemons is a monitor sitting on a certain server and more or less just checking if the other daemons are up and running - but also offering a SOAP interface to get the 'current situation' on the machine.
Whenever the detected situation does not correspond to the defined (i.E. a process which should be is not running) it is started up.
This part, I implemented via a system() call that starts the other process.
I was a little confused when lately often this monitoring process would not start because it could not bind its server port - the one the SOAP server is listening on.
And confusion got bigger when netstat told me that the port is assigned to one of the processes that were before started by the monitor..?
Even better: if I then kill the process of which netstat tells me it holds the port, the next netstat shows the next monitor-started process as the one listening on the port..
Only if I kill all the processes that were started by the monitor, the port is released and I am able to launch the monitor again.
Now I wonder: why does this port get 'reassigned' to the children - and most of all: how can I prevent this from happening?
I'm having all kind of problems with my ubuntu 10.04 which I updated to from the 9.10. I'm doing a clean install so I'd like to have this very clear. Right now I have three users:
1-the administrator
2-the one I use for music production
3-a general one.
The only one in which I can access synaptic is user 1. My question is: is there a way I can access to synaptic from the other users? I thought that you picked an admin password and if you were on a non admin account, by typing it you could use synaptic.

I created some users on my Ubuntu 10.0.4 machine a long time ago (whilst experimenting). Some of these users can login to the system, and others were prevented from login in. I can't remeber which ones can login. I have the following questions:
How do I find out which users may login to the machine? How may I disable an existing user account from login in? How may I re-enable a previously (login) disabled user account so it an login again?
I have a server setup with all my web development stuff in /var/www and in several sub-folders within that. (each project having it's own folder)It works great with one FTP account. But recently I've been getting help on a projects from a buddy of mine that freelances, and have made him an FTP user account as well. All is fine, except for when he tries to edit a file and gets a permissions error.
Here's the issue, I don't want us to have the same FTP login, but all the files are currently owned by my user name. So, when he logs in to edit a file, he can't because I'm the owner, and the files are set to 744. Will I cause any harm by adding both users to the same group (www-data) and chmod'ing the files to 775 so that we can both access and modify the files?
Quick question - I would like to know how to prevent users from accessing directories above the directory used for ftp. I'm running proftpd and I'm able to connect outside of my LAN, however all user accounts can click "Up to higher level directoy" and access everything, all the way up to the root directory. How can I make this unaccessable/not visible to users connecting to my server, allowing access only to the directories and subdirectories I have specified?

Is there a "correct" way to set up a shared folder between two local users using only EXT4 that will allow both users read & write access to everything in the folder?
Here's my scenario: My wife and I use the same computer. I want two separate user accounts (mine and hers), but I want ~/Music to point to the same location for both users so that I don't have to duplicate all of the files.
Too protect the innocent, I'll use Jack and Jill.
So say Jack downloads or rips an album:
"/home/jack/Music/Radiohead/Ok Computer"
I want Jill to be able to able to create a folder:
"/home/jill/Music/Radiohead/Hail To The Theif"
I know the basics of symlinks so I can get /home/jack/Music and /home/jill/Music to point to the same place. I also have Jack & Jill in the same group.
The problem I'm having with my test setup is when Jack creates "/home/jack/Radiohead", it is set up to where Jill can read, but not write. So she can play songs from Ok Computer, but if she wants to download Kid A, she has to go in and manually change the permissions on Radiohead first.
Also, while I might set up multiple directories this way, what I DON'T want is for Jack to be able to modify /home/jill/otherdir where otherdir is just a regular directory set up with default permissions.
Oh, and as an added bonus, it would be nice to set up another account (i.e. a "guest") with limited permissions that can read, but not write/modify.
I just created a 2nd user on my computer. I've got the hard drive that ubuntu runs on, and then a 2tb drive for media. If the 2tb is mounted on my desktop, it won't show up on his desktop even if I'm logged out. It won't show up on his unless I unmount on mine.
If I'm logged out I'm obviously not using it. So why doesn't it show up? He has all privileges. Is there a way to make this work without having to unmount?
I'm running karmic btw. If you need computer info let me know what to type into the terminal and whatnot and I'll paste it all here!
I've got a Samba server (CentOS)(I swear all my non-work boxes are Ubuntu) that has been working fine in our Active Directory environment for a long time, now that Windows 7 has been forced upon us, we've noticed that Win 7 users aren't able to authenticate to this server unless they access it using the IP address, e.g. \192.168.1.22. We've tried the different Windows 7 registry hacks and nothing makes a difference. We were advised to update Samba and we did to 3.3.8. However, this being a virtual machine, upgrading a clone of this machine did work, the configuration was identical, except the hostname
View 9 Replies View RelatedThe question is related to one single desktop machine, with 3 users.
1) the superuser (me)
2) My elder son

As superuser, I can access the network (internet router) via "Wicd" perfectly well.
Both Client users can't.
Do I have to give them special user priviledges? If yes, which ones?
All I want is a simple Samba installation that anonymous users/guests can access. I have modified the smb.conf file so much using 'tips' that should enable a simple folder share. Nothing works. If I share the folder using Nautilus share then the folder is accessible without any credentials from only Win7 and android ES File Explorer. XP can't see the folder, nor can any other linux device. I want to switch to linux as a main OS but without shares it's not practical. Does anyone have a stripped down smb.conf which provides guest access to a single folder?
Here's the latest testparm -s

$ testparm -s

Debian 5.02 on an AMD 64. I removed iceweasel and installed Firefox. On my account, I can access the net ok from FF, but when I login as another user, I cannot get out.
During the iceweasel removal, I suddenly got dumped out. Trying to recover I ended up restarting the box. I then again went to the root and 'aptitude remove iceweasel' and it came back ok. Then I installed FF per [url]. This worked fine on my 32 bit laptop btw. I even added a guest acct and FF worked, but not so on my 64 bit box. Any ideas on where to go?
And the reason for FF was that some media was not playing with iceweasel as it was perhaps too old? I didn't think 3.06 was that old myself, but when I installed FF, the sites that weren't playing fired right up.
I want to restrict access to certain directories to my ssh users but allow them to read files by known path from there(mostly it's meant to be done by applications).

How do I create user accounts (for our developers) that have access to the /var/www directory - do I create accounts then add them to the www-data group? Or should I make a special 'webdev' group and give it access somehow?
I am currently running Ubuntu Server 9.10 as an FTP server. It has become a necessity to allow users access via SSH terminal or sftp via WinSCP. I need to be able to monitor what users are doing at any given time and be able to pull up each users activity history. Essentially I need to be able to pinpoint who modified a file at what time. Also what is the best method to monitor things like nmap probes?
View 1 Replies View RelatedI want to configure a remote internet facing server as git server. I would like to restrict access to the server to a few systems (access is restricted to select computers, not users). I first thought of using ssh key, but the key can be copied to another system hence that alone is not sufficient. I am having a dynamic IP, so simple IP based firewall blocking is also not possible. I was thinking about the possibility of using both SSH Key and IP based access. Is it possible to update the firewall rule whenever my ip gets changed?

View 3 Replies View RelatedI find FTP server software confusing in Linux. Using ServU for Windows for an example, all I need to do is to create users via the ServU interface and choose a folder I want that user to have access to and their permissions, and viola, they can connect to that directory, and that directory only.
But in the the land of Linux, it apparently can't be managed this easy. I have a web server with multiple domains, and therefore multiple users need access to their own web root. So with that in mind, what FTP server software should I use (there are plenty out there) and how would I go about to create a user per domain, so that they can log in using FTP to manage their site, and only have access to their own web root, and nothing else?
I use this command line to add an FTP user:
useradd ftpuser1 -d /userdir
This works, but I don't want to give Shell access to the users.
I tried this:
useradd ftpuser1 -d /userdir -s /sbin/nologin
but then user can't login at all - not into FTP and not into Shell.
It looks like my web/ftp server has been hacked but I'm not sure how. I logged in tonight and found I had new mail. I read it and found some e-mails that had failed to send because I don't have mail setup (luckily). The e-mails were trying to send my user name and password to the e-mail address lostsoul2k@ymail.comI've no idea where to start, I use SSH, FTP now and then and it hosts a Wordpress site. The FTP users do not have access via SSH, only my user ID. However, the e-mails also contained another user ID that only has FTP access to the server.I've looked through the logs for rkhunter but it doesn't look like it found anything.
