Networking :: Run The Job Under A Root Account And Deny Read/write Access To A Normal User?
Jan 18, 2010I'm setting up Ubuntu Karmic on my sister's old computer for my nephew, he's quite young so my sister asked to install some content filtering. I'll first setup an OpenDNS account and I've installed and managed to get dansguardian and squid working on a virtual machine to try it out. so far it's working pretty well, but I need to secure it form the inside out.
I was thinking of blocking specific outbound ports so he could not bypass the proxy. because by default the firefox configuration can be easily changed. so I have a couple of questions.
1. is it possible to block outgoing ports on Ubuntu?
2. is that the best method?
3. is there anything else I should be aware of to prevent subversion?
lastly, this question is probably unrelated to this board but I've set up a cron job to update a dynamic ip with OpenDNS, the problem is that the password is in clear text in the user's crontab, can I play with permissions? is it possible to run the job under a root account and deny read/write access to a normal user?
General :: Limit "su" Usage To Only 1 User Account?
Apr 29, 2011I've noticed that "su" can be run from any user account so long as the user knows the root password.What if I want to limit the ability to "su" to only 1 user account? For example: Pretend my desktop has 4 different user accounts. Currently each user account could run "su" for root access if the person sitting in front of the screen knows the password.
1) Could I somehow make only 1 of the 4 user accounts able to "su" into root mode?
2) If yes, then would doing so have any side-effects?

Networking :: In PPTP Server - Limit Bandwidth Per User & No. Of Connection Per Account?
Apr 2, 2010recently i rent a xen vps intended to setup a PPTPD vpn server for me and my friends. so we can by-pass the great firewall in china and get back on ....., facebook and stuff. i have already setup the server and i can connect to it without any problem. but i still want to do some further configuration the server:
1. i want to limit the bandwidth to 400k/s per connection.
2. i also want to limit the max connection per user a/c
i have some thoughts on the 2nd requirement. in the user configuration file of /etc/ppp/chap-secret, you can specify the range of ip the user can get, does it limit the max connection per user a/c? or they can connect anyway, just every now and then a box pop up says conflict in IP address?

Oct 2, 2010On a Fedora Core box, I have a normal non-privileged user and I also have sole access to the root account. Because I am the only administrator of this box, I frequently su over to root for administrative tasks. The problem is that many of the user configuration I've become accustomed to are only configured on my day-to-day account (.vimrc, .bashrc, .screenrc, etc). Other than giving my day-to-day user account privileges to perform administration tasks, how would I go about sharing configuration between these two accounts?

View 1 Replies View RelatedGeneral :: Disable - Non-root Shell Command To Find If A User Account Is Enabled Or Not?
Aug 10, 2011Is there a non-root shell command that can tell me if a user's account is disabled or not? note that there is a fine distinction between LOCKING and DISABLED:
LOCKING is where you prepend ! or * or !! to the password field of the /etc/passwd file. On Linux systems that shadow the passwords, this marker flag may be placed in /etc/shadow instead of /etc/passwd. Password locking can be done (at a shell prompt) via password -l username (as root) to lock the account of username, and the use of the option -u will unlock it.
DISABLING an account is done by setting the expiration time of the user account to some point in the past. This can be done with chage -E 0 username, which sets the expiration date to 0 days after the Unix epoch. Setting it to -1 will disable the use of the expiration date.
The effect of locking to to prevent the login process from using a supplied password to hash correctly against the saved hash (by virtue of the fact that the pre-pended marker character(s) are not valid output character(s) for the hash, thus no possible input can ever be used to generate a hash that would match it). The effect of disabling is to prevent any process from using an account because the expiration date of the account has already passed.For my situation, the use of locking is not sufficient because a user might still be able to login, e.g. using ssh authentication tokens, and processes under that user can still spawn other processes. Thus, we have accounts that are enabled or disabled, not just locked. We already know how to disable and enable the account - it requires root access and the use of chage, as shown above.To repeat my question: is there a shell command which can be run without root privileges which can output the status of this account expiration info for a given user? this is intended for use on a Red Hat Enterprise 5.4 system.The output is being returned to a java process which can then parse the output as needed, or make use of the return code.

View 3 Replies View RelatedUbuntu :: Root User Account Is All Messed Up?
Oct 8, 2010A while back I don't know what I did but I messed up my root user account and now the password that I think is supposed to be for the account doesn't work anymore.In an attempt to fix it I rebooted and went into recovery mode and then edited the sudoers file. This appears to have been good enough to be me by but now I'm running into problems installing or changing configurations in gnome. For example, I just installed Asterisk via the terminal the other day and had no problems because I could use sudo. But just now I tried installing Gastman via the Ubuntu Software Center and of course it asked for the root password.I entered my usual root password when I use sudo and it doesn't work.
I then went to the terminal and entered sudo apt-get install gastman and it worked fine becuase I used my sudo password for my account. So it seems I can do things just fine via the terminal but when in gnome it doesn't work. I went into the Users and Groups section in Gnome to attempt to set or change the root password but of course I have to unlock the application which requires the root password.

I'll call it 'masterskop' as it is my forum name here, but not on my computer.Would it look like this in the sudoers' file?My purpose is to get access to all the folders and files in the 'File System'. The root and lost+found folders have 'Xs' on them...No access! And for example, under properties of the 'var' folder it states that 'you are not the owner, so you cannot change these permissions.' How can I get access to all of it everytime I login as the main user of my computer? I do not have anyone else using this computer.I did edit this file and used my real user name ... logged out and logged back in and still I do not have access/edit these folders and files.

General :: How To Give User Same Access Level As Root - Fedora 14 - KDE
Apr 9, 2011First, I am new to linux I just finished installing Fedora 14 on a different PC which I will be using solely to explore Linux. However the first annoying problem I encountered was that I can't do a lot of things without Linux asking me for the root password. This has become really annoying, I want to stop fedora from asking for root authentication every time I want to explore something here and there.
Among the work-arounds that I've tried and didn't quite work for me are:
1. login as root on the kdm - I can login as root but because I am also encouraging my sister to explore fedora 14 she needs the same access as root too. We have our own preferences so we both need individual accounts that have same access level as root.
2. change userid to 0 (same as root) and modify groups to be exactly the same as root's groups - very bad solution, what it did was make my user a sort of "alias" for the root. It basically uses the same /root/ folder, same settings and all that stuff. Again, my sister and I need separate accounts for a more personal feel.
3. use terminal and go sudo, sudoers, etc - very bad idea, I want to explore using the kde gui. And again I want to eliminate the inconvenience of having to type things over and over again. I'd rather type the password over and over again than having to use terminal and sudo everything.
4. beesu, gksu - anyone knows how to make linux automatically wrap everything with beesu/gksu?
since we are just exploring, we are willing to trade the systems, integrity and security for the convenience of having freedom to explore everything in it. I don't care, it could blow up the pc for all I care (it's old and for experiment anyway).
This exploring linux of ours is a make or break for us to using linux. If there is no solution to this problem, we'll probably scrap the whole "migrate to linux" idea.
I thinking of making Linux recognize our user id the same way it recognizes uid 0 but I have no idea how to do this.

OpenSUSE Install :: Cannot Log In To Any User Account Including Root After Logging Out In 11.4
Apr 17, 2011My install of 11.4 has been running perfectly for for several weeks now. But- (always a but) today it started acting up. I cannot log in to any user account including Root after logging out. After a cold boot I can log in again anywhere but after logging out I have to reboot again then I can get back in to any account once. After logging out any attempted log in causes the splash screen to blank for a few seconds and then it comes back with the previous successful user name log in but typing in the password blanks the screen a few seconds again. Clicking on a user account also blanks the screen a few seconds and then it again comes back with the previous log in users name.
