Security :: Using Sudo Instead Of Root Be Safer?
Apr 5, 2011Consider: [URL]
In security terms, would using sudo instead of root be safer? I'd actually prefer to use this if so; I like sudo an awful lot. (It's Mark Shuttleworth's fault)
General :: Safer No Password Sudo?
Nov 22, 2010This is on my host machine. I'm the only one using it so it's fairly safe, but I have a very complex password that is hard to type over and over. I use the console for moving files around and executing arbitrary commands a LOT, and I switch terminals, so sudo remembering for the console isn't enough (AND I still have to type in my terrible password at least once!) In the past I have used the NOPASSWD trick in sudoers but I've decided to be more secure. Is there any sort of compromise besides allowing no password access to certain apps? (which can still be insecure) Something that will stop malware and remote logins from sudo rm -rf /-ing me, but in my terminals I can type happily away? Can I have this per terminal, perhaps, so just random commands won't make it through? I've tried running the terminal emulations as sudo, but that puts me as root.

View 9 Replies View RelatedUbuntu Security :: How To Make A Transparent Firewall
Apr 14, 2010I'm involved in a project to students set up a network security training lab using vmware. I want to simulate (in a very rough way) scanning through a poorly configured router or firewall. The easiest way I can think of to simulate this is to use a linux vmware image with two virtual nic cards to act as a firewall with the attacker on the outside network and a domain controller, web server, and database server on the inside network.
I would like to start students off with a firewall script that exposes everything on their internal network to the attacker. Is there an easy way to (mis)configure iptables to do this?. The model I'm trying to replicate is something like this. Attackers were on a 10.10.x.x network, defenders were on a 192.168.x.x network. As an attacker I could nmap 192.168.x.x and see every machine and every service on the defenders side even if they moved a service to an unexpected location. how I can implement a similar configuration using a linux image as firewalls/routers in vmware?
Ubuntu Security :: Can't Change Password / Make It Possible?
Jul 21, 2010When I go the the Change Password dialog box and type my new password, the box seems to stall forever when I try to change my password. The Authenticate and Change password buttons are grayed out but the Close button still works and when I click on it the box will close without changing my password.

May 3, 2011I got BT's repo's set and ready to install, tho I haven't installed them all just yet cause I not wanna crash the system, so I guess what I am asking has anyone sucecfully done this and what are the specific risks here. I have uploaded crunch and that works fine if I do it manually from the command line. the kernal seems to be update-able as well to BT's Kernal, I am not sure if I should do this or not in fear it might crash the Ubuntu system somehow. I guess what I might do next is install everything but the Kernal and install the executable links to the drop down menu by hand per the menu structure.
What I would ideally want is to have all the functionality of BT in Ubuntu which is pretty close to where I am at. Also, when I am done I want to make a live CD of this system so that I not have to do this ever again as it is very time consuming. What program would be used for that? Would any of my user data transfere? I don't want my user data to be transferred to the live CD just the raw system data etc. Anyone done this and would like to chat via skype? that would be best, but I'll take any help I can get at this point. I am using Ubuntu 9.10 for all this.

Ubuntu Security :: Way To Make Sure That Samba Is Turned Off On Laptop?
Sep 26, 2010I have Ubuntu 10.04 installed on my laptop which is wirelessly connected to the router. I have a PC which is Windows XP that is connected wired to the router.Now - I understand that Ubuntu is secure out of the box and so there is no need to worry about configurations. However, a past couple of updates in Ubuntu and I am seeing updates for Samba.I understand that Samba is used for file transfer between Windows and Linux.
Is Samba turned off by defult when Ubuntu is installed - despite having a WinXP computer connected to the router? Is there any way to make sure that Samba is turned off on my Ubuntu laptop?I don't want to transfer any files between my laptop and WinXP. If Samba is enabled, then a Firewall is needed to be configured (I assume), and to me that is sort of pointless with Ubuntu.For arguments sake, if Samba was enabled on my Ubuntu laptop - what would happen to my security?
Ubuntu Security :: PGP - Make The Tarball Available For Other Users To Download
Dec 20, 2010Got PGP 6.5.8 for Linux working with Ubuntu 10.10.

I put the two .deb files in a tarball (tar.gz) and would like suggestions as to how to make the tarball available for other Ubuntu users to download.

Apr 26, 2011I'm a little security paranoid, there are a lot of times that my terminal is available to prying eyes and listless fingers. As a security minded individual, I would like to make sure to lock down my Ubuntu (11.04b3) install in one of the best ways I can think of, and require a dongle to access my box. Is this something any of you other security minded people have done?
What are other great ways to lock my terminal? I would like to make sure that not only the "average" user, but also the ABOVE average user will not be able to penetrate my system without a key. Let me know what you think, and other measures I can take.
Security :: How To Make A Unified Login
Mar 24, 2010Running this software:
Linux 2.6 on a hacked LaCie NetworkSpace
installed SSHd 5.4
installed Samba 3.4
installed lighttpd 1.4
installed ProFTPD 1.3
I want:
Login with my account and same password on all of those. When i use passwd, the change should be reflected on all of them.
I have:
Samba uses encrypted passwords, and i must change passwords for samba with smbpasswd.
lighttpd uses separate password file, must change by hand.
ProFTPD and SSH use system login (/etc/shadow).
So far i found two possible solutions, but can't tell if i understood them right or how to achieve them: use LDAP as auth backend If i could make LDAP my auth backend, provided this is possible at all, lighttpd would use this directly, and PAM would use it for system login. Nevertheless, actually this can't work as Samba uses encrypted passwords. Correct? use Samba password backend, then make LDAP use that If passwd, login, etc would use Samba, i would work everywhere with MD4 hashed stuff. Lighttpd would send plain passwords (HTTP basic auth), and query LDAP, which in turn makes an MD4 hash, and tests for Sambas passwd. Will this work?

Ubuntu Security :: Make Smart PDF Submission Form Work With TOR?
Jul 29, 2010One of my friends wants to make a submission in the following Smart PDF online submission form:
[URL]
But whenever he loads the url it opens Adobe acrobat reader which I assume will bypass TOR because the form requires Javascript to be enabled. The form will not submit unless javascript is enabled.
So how can my friend submit the adobe smart pdf form with javascript enabled while still being anonymous with TOR?
If it's not possible with TOR, what other free services could my friend use?
Ubuntu Security :: Install A Firewall GUI And Make Special Settings?
Aug 19, 2010I just erased WinXp and installed Ubuntu on old laptop. I intend to use it later ot connect to public Wi-Fi. Do i need to install a firewall GUI and make any special settings? I didn't encrypt home folder during installation. I probably should have done it. But i am already low on system resources (224MB ram, 1.2Ghz CPU). Would that use up any additional resources? Would it make computer run slower? Can i still encrypt the home folder after i installed the system?

Oct 24, 2010I'm sure most of you know that making a file or folder hidden is simple in the Linux world: Add a period (.) before the name. However, if you were to save such a file or directory to a flash drive, it would only be hidden on Linux systems. If you plug the flash drive into a Windows machine, Windows will happily show the file.Is there a way to make cross-platform hidden files?

In ubuntu there is a usefull button "start guest session"..but here in fedora I can't find it...So, I create a new user and I called it "Guest" and I eliminated the password, so they can access also without me... but I have some problem:a) I set the home directory of this guest in /tmp/guest thinking that in this way everytime the home directory will be clean... but this doesn't work...b) is there a way to prevent in all cases this account to autenticate as root? So, if they try to install something it hasn't to show the box "autenticate as root", it has to say only "you can't"

View 6 Replies View RelatedUbuntu :: Make Computer Accessible Without Opening Gaping Security Hole?
Mar 4, 2010my son is 15, autistic and mentally retarded. he is moderate-low functioning and loves to watch barney the dinosaur, thomas the tank engine and other young children's programming on videos on his computer. he can talk in a limited way and can read out loud at about the first-grade level, though he seems to have little or no comprehension of what he's read (hyperlexia).i'm having problems with viruses and spyware because he lacks the judgment that keeps the rest of us from clicking on every window that pops up. we've had a particularly nasty crop of ad-ware viruses lately that pops up graphic porn ads even when the browser is closed. i've had enough of this.
the computer is an ancient dell dimension 4600 desktop (circa ~2002) running windows xp. i've run ubuntu from a live cd and installed flash as a test. videos videos play fine, so that's not a problem. i don't really want to replace the computer becasue it still works and is only used by him to run firefox. i am willing to buy a new computer if that turns out to be the only option.i've been using ubuntu exclusively on my laptop for several years and i would like to remove windows from his computer and replace it with ubuntu. i'm wondering how i can make his computer as accessible as possible to him while not sacrificing too much security.my son has very poor fine motor control over his hands. he can use a mouse with some difficulty, but using a keyboard is out of the question. he can use the mouse to click on the shortcuts to his favorite videos, but i can't think of how he would be able to enter a password for his account. not only does he have the fine motor problem, but he is not able to remember any usefully secure password.
does anyone have any ideas about how to make his computer accessible to him without opening a gaping security hole? two ideas that i've kicked around are creating a user with absolutely the minimum privileges required to use firefox and no password or finding some way to enter a password that doesn't require a keyboard. i haven't come up with how to implement either of those ideas successfully.
