Ubuntu Security :: IPBLock Operated Before Or After?
Nov 9, 2010
Does anyone know if IIPBlock does it's operation before IPTables completes or after? I'm using a KVM as a Router and GuideDog is Forwarding all HTTP/HTTPS to my KVM Web Server. When looking at my web access.log I see CHINA doing it's stuff, but IPBlock is not blocking that IP (58.218.199.147) on the KVM Router.Before doing the KVM Router and just receiving HTTP to mu KVM Web Server, I always had logs of CHINA, but now I don't. So I'm assuming GuideDog is rendering IPBlock useless.Can anyone let me know if your able to connect to my web server at I would like to check even if this setup is working. Because I have a seperate access-thegardenofedenblessing.log for my domain then I do for my localhost (access.log) and CHINA is showing up on my localhost log.

I was looking for a similar program to PeerBlock on Windows, as most/some might know it's the project that took over after PeerGaurdian halted. So I have installed IPBlock and was having issues with updating the lists so i removed them, re-added them and still cannot. I can't import lists from URL's either without getting the same error. Kinda seeming like a waste of time right now...
Code:
ipblock[7147]:error:update of badpeers.gz failed
ipblock[7147]:error:update of level1.gz failed
ipblock[7147]:error:update of level2.gz failed
ipblock[7147]:error:update of Primary failed

I have totally exhausted my search to find IPBlock. I use it on my other Ubuntu machines but for some strange reason I cannot find it anywhere for my Ubuntu 10.10 Maverick. I know where the iplist is but not the actual file IPBlock download

Never done it before, don't know how but its due next week. I am a computer systems student and have been required to built a hardware that will be operated by a program in G++ through the parallel ports. The hardware, thats a piece of cake, the software, now that's were the real problem is. I don't even know were to start.

If I'd added blocklists from [URL] the same ones used by IPBlock (bar a few) would it be futile to use IPBlock too?

Im running ubuntu 10.04 and I cannot get ipblock to update its lists. I've checked the ipblock.lists and the urls listed are working. When I go to update it gives me a different error code each time for the lists. Ipblock will load up and work but not with updated lists,

Just as the title says. Why am I required to input my user password to launch this program? I am using 10.04 Ubuntu and this requirement does kind of annoy me. I like making a second account that can admin the system, and my main account has the admin option disabled in the 'Users & Groups'. I read it's secure to do this, but I see other downsides. Firestarter too requires a password to load it's GUI. Is there any work around because I don't like leaving admin privileges enabled especially when I'm not at the computer.

System responds (i'm translating from Italian):
"Unable to run the command '/usr/sbin/ipblock start_gui"
I checked directory /sbin, but there is no track of this "Ipblock star_gui". I have a Suse 11.4 updated system.

To avoid having to input a password for the keyring each time I connect to the net via wireless, I enabled the 'Available to all users' option in Network Manager. Now, my question is this. Are the 'users' it refers to just those created on this machine? Would a drive-by be able to use my network without entering the password?

1. I understand you can protect your files or directories in your website by setting file/directory permissions. The meaning of r w x is clear to me, but I'm not sure how to proceed... Starting with the index.html file, if I wanted to make it so that anyone in the world can read it but can't modify it, do I set its permissions to rwxr-xr-x? If I set it to rwxr--r--, would that mean the file couldn't be served? I mean, what does the x setting do on a .html file, how can a .html file be executable?
2. If file permissions work on the lines of owner-group-others, in the context of a website, who is 'group'? As far as I can tell, there's only the owner, which is me, and others, which is the world accessing the site. Am I correct in thinking that by default, say when creating a website on a shared hosting server, there is no group unless I specifically set one up?
3. My ISP allows the DynDNS.org service, meaning that I could serve a website from my home. It's too early to go that route just yet, but for future reference, I would like to ask about the server software called Hiawatha. It is said to be secure, but having read some evaluations of it, it doesn't seem to offer anything that couldn't be accomplished with Apache or Cherokee, it's just that its security settings are simpler and easier to configure. Am I right about this? Or does Hiawatha truly offer something that the other major server packages don't?

Conky can be used to display a variety of information on the users desktop. I wanted to use Conky instead to display the current status of security as reported by:
SANS Internet Storm Center
IBM Internet Security Systems
Symantec Threatcon
McAfee Threat Center
I therefore created 4 small scripts which download the current status from these sites, and set the colour of those status's depending on the current value.The conky configuration allows for a semi-transparent background - though this is optional.Attached is an example image showing the 4 different colours.Also attached is an archive with the 4.sh files, .conkyrc and draw_bg.lua (from here http:[url].....

I just installed Ubuntu on a desktop. Can anyone give me some guidance on installing basic security software? In particular, I'm looking for a firewall, antivirus, and anti-spyware/malware utilities.

I already posted a topic similar to this concerning the Desktop OS version, but this deals with the Netbook because unlike the Desktop, the Netbook is less cooperative. Allow me to elaborate: Today (or rather yesterday since it's not after midnight where I am), I changed my password because I was hopelessly confounded about how to get my Wireless Network card up and running after it had been installed and I was allowing my dad to use it. This issue has since been resolved, however...
When I chose my password during the original installation, there was no mention of it being "too simple." This is where the Desktop OS and the Netbook OS differ. The desktop will let me change it in the terminal without any errors. The Netbook will not. When I've attempted to revert it back to the original, it will not let me do so in the User Profile or in the Terminal. The Passwords and Encryption Keys application also does not appear to help.
So now even after I've changed it to a different "complicated" password I am still prompted to insert two different passwords since I changed my user password but I am unable to change the password I input during the installation. A bit screwy methinks. This is extremely important. I'd like to know how to change the original installation password.
If I can't change the main password on my laptop then this is a serious potential security breach just waiting to happen (especially since it's on a laptop and I will be hauling it around with me) and I will most likely install a different OS if this isn't resolved --- It would be very unfortunate since I spent the whole day fixing it and I really enjoy the interface. Luckily I can live with this on my Desktop since I'm not going to be hauling it around with me everywhere when the school year starts.

As it stands I have a small home network operating behind my modem/router. Some of the ports on this are forwarded to my PS3 for gaming but I was looking at forward some for my file server.
At the moment I've forwarded port xxx22 to port 22 on my server for SSH for instance. ANd similarly 21 for FTP (although it doesnt seem to want to connect for any more than a few seconds using that). What I was thinking of doing was placing a small website for a handful of ppl to use on the server too and port forward again - xxx80 to 80. It works just fine but I'm a little concerned on the security front.
As I've moved the port to something different from the outside world I'm presuming I will have already cut the potential for malicious folks to wander in but is there anything else I should be doing? At the moment there's no firewall operating on the server, usually as its hidden behind the modem/router. But if I open this thign up more permanently what should I be doing? I've read a few articles on it but I'm always left with the overwhelming thought of "Thats if theres no firewall in my router" as they just seem to do the same.

When posting results from ifconfig, it shows the hardware address of etho, etc. Would you consider that to be a security risk ?

I'm concerned about security of having a LAMP server on my laptop as having any server makes the system less secure. However, if I were to create a new partition and install a lamp server on that and only use it when offline, would the security of my main partition be affected at all?

The default Firewall ufw is not enabled by default at the time of installation and it has to be enabled by the user.Isn't this a security risk or is the user whether ufw is enabled or not secured from external threats?I am not much knowledgeable about network security But I am trying to understand the Ubuntu mentality behind this default setting.

I've recently been running a game server from my desktop, as well as a web page to accompany it.I use the ports 80/8123(HTTP)/5900(VNC)/50500(GAME)/5839(ADMINISTRATION).What's the best solution to protect my server from security threats? On a side note, I plan on adding a MySQL server later, but I want to keep it local only.

Having read on the forums about some of the dangers of running Wireshark as root, I would like to know if anyone can suggest some alternative packet sniffers/network analyzers which will offer similar results but without the security issues. I am using Karmic Koala on a Fujitsu Siemens laptop with wireless router (firewall enabled)

So yesterday I receive a copy of the SANS @RISK security vulnerability newsletter, and, lo and behold, Mozilla's Firefox and Thunderbird are on it yet again. (Yeah, I know, shocking, isn't it?)So I quickly check what versions I have installed. Yup: Vulnerable.I check whether updates are available.These are pretty serious "remote code execution" vulnerabilities and the status is "vendor confirmed, updates available." So why isn't my 9.10 desktop's update manager telling me updates are available?

I have read that to improve security in Ubuntu a good fix is to make the /home folder tree non-executable by default. This would mean that malware could not run in the /home tree without changing the setup.Is this a viable change, or is it just icing on the cake, any one any thoughts on this.

I always use VNC to check my server for updates, and this morning I started the xvnc4viewer to vnc into my server and it keep asking for a password. I never setup a password because I do this local from my laptop, and I am the only one who uses my laptop. I had to go to my server and check the setting in System > Preferences > Remote Desktop and found them all changed. There was a password setup and there was a check mark in the you must confirm each access to this machine there some security update that changed all these setting? Sometimes when I do updates I don't know what is being changed on my server

I'm new to server admin, so my question is based on what may be a bad assumption. With a server, my assumption is "if it ain't broke, don't fix it". In other words, I'm not really interested in upgrading the software to the latest and greatest if I already have stuff working on the server.
However, the one place where I DO want to constantly have upgrades is for security patches. How do I apply security updates to Ubuntu Server... and ONLY security updates?

just migrated to Lucid from Jaunty and noticed that the login startup screen looks more like windoze (shows all authorized users).One of the endearing security checks with Unix was that if you had access to a console you had guess both userid AND password - the system wouldn't tell you which was wrong.I feel that we have lowered security by making the list of authorized users visible on a console. Is there any way to turn it off and force users to enter both userid and password?

Or do you just use Ubuntu feeling safe enough without them? If you do use AppArmor and other security measures, what do you use them for? Obviously Firefox and Chrome would be two things. But what else?
