Ubuntu Servers :: Restrict Access To Particular IP?
Oct 7, 2010I'm running Ubuntu Server 10.04 32-bit.I'm looking to find if there is anyway I can lock down ubuntu so that remote access, whether it be SSH, ftp, apache.etc can be only accessed from a certain IP range, or a certain set of IPs?Essentially, we'll say the Server IP is 192.168.1.32, and I want the IP addresses 192.168.1.33-50 to be able to access the server, but no other IPs.I am in a switched environment, router's are not allowed to be placed on the network, and I do not have access to a DNS or DHCP server.Is there a way to do this in on the server via a configuration of some sort?

General :: Restrict Web Access So *only* Firefox Can Access The Web
Nov 15, 2010I'm a terrible procrastinator, it's awe-inspiring annoying and stressful. This in combination with being a information-holic makes the Internet fairly lethal to me; I risk failing my college course because of it, so trust me when I say I'm deadly serious about this.
However, I think you guys may be able to help out, and maybe this will also help some people here with similar problems:
Because so much of my time is taken up with Interwebz, I thought to carefully restrict my internet use. It's not prefect, but it's part of a solution.
To date: I have Firefox and the ProCon extension which uses a whitelist of websites I can access. The extension cannot be uninstalled/disabled and I use a long hex password split into 3 parts, two of which my friends have (so I have to ask my friends for the password parts in order to update the whitelist, hence making it socially awkward to fritter away time online).
So far, it has worked a treat and I'm really pleased with it.
However, this is the problem:
I need to restrict web access so *only* Firefox can access the web. That way I cannot use Chrome/Opera, or even (shudder) use wine to run Internet Exploder.

Jul 28, 2011I'm running Natty and have made two logins on the system. One for myself and family and one for the kids (teens 14-15yr) to play in without Internet access via Admin "Users and Groups". I have hidden the Internet software icons on their screen amongst others i don't want them to see on the menus. On our screen I use a Firefox addon called "Web Of Trust" that can be configured easily for the kids and another addon called 'Blocksite' that I can selectively use for them and myself etc.
I have found out that they have still been able to get on to the net somehow under their login. Will have to observe again!! In the users settings for the kids the tick box for 'Internet'and 'use modem' access is un-ticked so I presumed that would be enough! Not so!!

View 1 Replies View RelatedUbuntu Servers :: Restrict Users To Only SSH Tunnel - No Shell?
Jul 21, 2011I have an Ubuntu 11.04 instance running on Amazon EC2. I am currently using it as an SSH tunnel/SOCKS proxy. Most of my Net activity is on a Windows 7 machine running PuTTY. This setup is working very well. So well that a few of my friends have expressed interest in accessing it. Question is, how do I share this proxy, without giving away my private key and root access? I would like to limit users to only being able to set up an SSH tunnel/SOCKS proxy, with no shell access. What other security measures would you recommend for such a setup? I googled a bit and saw references to rbash and chroot. I have already changed the SSH port, and set the EC2 firewall to allow inbound SSH only from my ISP's address range. My friends use the same ISP. They would probably be running Windows 7/Vista, and PuTTY too.
View 4 Replies View RelatedSecurity :: IPTABLES - Restrict Internet Access Based On Time Of Day And MAC Address
Feb 6, 2010I am trying to configure my Linux router to restrict Internet access for one computer on my LAN. It needs to be restrictive based on the time of day and the days of the week. I am using the MAC address of the computer to single out the one computer that needs to be blocked. However, this is my first attempt at making any rules with iptables, and I am not sure if I am doing this right. If some one can take a look at this I would greatly appreciate it. This is what I have done so far.
Here is my thinking. Create a new target. Check the MAC address, if it is NOT the offending computer return to the default chain. If it is the offending computer check that we are between the allowed hours and dates and ACCEPT. If we are not within the time/date range then drop the packet.
Code:
Here I am trying to route all packets regardless of the computer on the LAN into the blocked_access chain for checking.
Code:
Is it a good idea to route all traffic through the blocked_access chain? I do run other servers that are accessible from the Internet, so I am not sure how this setup will affect that. I also use shorewall on the router to setup iptables for me. How would I integrate this with shorewall?
I am using squid to block access when he is using the web browser. However, he is still able to play games(World of Warcraft) and the like.
I am using Debian sid, iptable(1.4.6), shorewall(4.4.6), kernel 2.6.32-trunk-686.

Ubuntu :: Write Access On Raid5 Mount And Network Access
Apr 22, 2010I'm running ubuntu 9.10, and created a softraid5 with no problems. Now i need it to automount with user read/write access, and i need to make some network share folders. My fstab has the following line for the raid:
Code:
/dev/md0 /media/raid auto rw,user,auto,exec 0 0
After i mounted it, i changed the permission with:
Code:
sudo chmod 777 /media/raid/
So now i can create folders and files on it.
Then i created some shares, one with guest access and other with no guest access.
Now the questions:
1) If i access the guest shared folder via WinXP, i create files and folders, but they appear locked on ubuntu, so i cant access them until i change the permissions. If i go to proprieties/Permissions, the owner is "nobody".
2) What password do i need to use on WinXP, and i try to access the non-guest shared folded? Do i need to create a user just for that?
