Ubuntu Security :: Internet Security Status Feeds Via Conky?
Mar 29, 2010
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'm trying to set up Conky to show a number of RSS feeds, and while I can get it to show the raw titles of items how would I trim these titles down to a given number of characters (say, 40) and add an ellipsis to the end if text has been cut off? The length of titles by default can vary wildly, so if only for the sake of organisation it'd be nice to have a maximum title length imposed.
I found this thread that does something kind of similar for Transmission torrents, but I have no idea how I'd adapt it for RSS feeds. As it stands, the code (well, a sample at least) is simply:
Code:
SLASHDOT$hr
${rss http://rss.slashdot.org/Slashdot/slashdot/to 5 item_title 0}
${rss http://rss.slashdot.org/Slashdot/slashdot/to 5 item_title 1}
${rss http://rss.slashdot.org/Slashdot/slashdot/to 5 item_title 2}
${rss http://rss.slashdot.org/Slashdot/slashdot/to 5 item_title 3}
${rss http://rss.slashdot.org/Slashdot/slashdot/to 5 item_title 4}

In the Release Notes for Jessie, it is stated that webkit browsers do not receive security updates in a timely manner and so are not secure. It is recommended that one uses a gecko-based browser or Chromium for 'general' web browsing. Yet I haven't read anything about this elsewhere and I'm guessing a lot of people don't read the Release Notes, so perhaps it's only something I would only need to worry about if I worked for MI6?
Anyway, Chromium and Iceweasel are becoming far too sluggish for my computer. I would want to experiment with Konqueror, Midori, Epiphany and Opera, but don't want to do anything insecure. I'm of the understanding that without Mandatory Access Control, exploits in applications often allow attackers to access all of the user's files; I want to avoid that.
On the Opera page on Debian Wiki, it says 'Opera is a non-free (proprietary) software. It isn't supported by Debian. It's probably wiser to use a supported web browser ! '.

See system logs and 'systemctl status' for details [FAILED]"and in the application "services" in the applications menu,t shows an exclamation warning and says that "This unit has failed"

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?

CentOS5.x We have a auto backup system that rsyncs all our vital data to a backup server over our network. The final step in this is to get the backup server to rsync with one of our remote sites for the off site backup. We have lately been visited by the boys from .ru and .ro due to good passwords we have managed to keep the visitor out of the network, we also changed out ssh port away from the default for better security.
We would like the backup system to be totally automatic, when I was reading up on the bruteforce attacks I read recommendations that we should have ssh that need passwords to be manually inserted for extra security. How secure is sharing NFS folders over the internet. we would configure only one host to have access to the share is this enough for us or should we think deeper here.

I am running UFW, which is set to deny everything but SSH on port 22, OpenVPN on port 1194 and HTTPS on port 443. SSH is set to only allow private key logins, and the root account is disabled. I have AppArmor running for all of my daemons (OpenVPN, Apache2, OpenSSH) and I have Fail2Ban running.
Is there anything else I can do to secure my server from the Internet (it is directly connected, there is no NAT between the Internet and my server).

Today I noticed my Desktop was being controlled remotely from over the Internet even though I had it set for 'local network only'. Foolishly I relied on this setting and hadn't specified a password or other security. The remote user had opened my Firefox passwords page and was perusing this when I pulled the plug.
All external checks confirmed that my router/firewall is actively blocking correctly. How could this happen? How can I prevent this in the future? I had recently install the Firefox extension for Weave Sync and wonder if that had anything to do with it?

I administer a desktop computer with ubuntu 8.04 in an university library. Since it works almost all night, to enable students to study, after some time I noticed some misuses of the computer during the evening, when there isn't many students. My goal was to disable users from accessing internet from 7pm to 7am, but also enable it if certain user was logged in (I use that user for torrent, and I seed on that computers from time to time). So I created a script that's being called by root's crontab, and here is the script's code:
Code:
#!/bin/bash
NUM=`who|grep myuser|wc -l`
#echo $NUM
if [ $NUM -le 0 ]; then
/sbin/ifconfig eth0 down
else
/sbin/ifconfig eth0 up
fi
Since I created the script, I actually never seeded anything, so I'm wondering now if that's going to work at all, and (also) is there a better solution for this.

I was hoping to set up a Kubuntu 10.04 Chroot on a PC with no internet access (I only have dialup anyway, not Broadband). All the information I have been able to find refers to downloading debootstrap in order to do this.I purchased a set of DVDs with all of the Ubuntu packages on them and created a single repository of them on my harddrive.Is there some way that I can create the Chroot using the packages on my hard drive without having to access the internet to download stuff as I do it?

I use vpntunnel.se and followed their tutorial for OpenVPN and it connects and assigns an IP. However, once the sequence is initiated and I open my browser I cannot connect to a webpage and get a "cannot resolve" error. I e-mailed their support and they suggested I change the DNS of my network settings. I did that but the same problem. Once I close OpenVPN my internet works again. It works in windows, so I know it is not my router...I use a wireless connection with my router. I don't know if this has something to do with anything...

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.

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.
