I'm trying to do an online security check on my Linux system.I would like to do a Firewall/Antivirus test. What free online sites do you know?For instance, I use ShieldsUp to test some firewall's components.Does someone recommend anything else?I still can't find a site that tests for the presence of virus/malware installed.Are there any?
View 8 RepliesI am writing my own anacron script that backs up my most important files from my laptop to my office pc regularly using rsync. However, sometimes my laptop is on when anacron starts the back-up job but my laptop is offline, so that it cannot rsync with my desktop. Is it possible to tell anacron to re-schedule the task to either the next time I'm online again or to some later date (preferably not the next scheduled time, but some time before)?
View 4 Replies View RelatedI'm new to Linux(Ubuntu 11.4), just installed it two weeks ago. I've been a member of Linuxquestion for about 2 or 3 years mostly lurking.I have building/buying computers for 30 years, first DOS,Windows 3.1, then Windows 95 through all to Win7.My question is for security of online banking and other financial things. Everything.I've been reading on here indicates that no Antivirous/Malware is needed. Being new to Linux, I can't tell if ClamAV is working or if is even needed.I had thought about doing banking on my wife's machine(Windows only) rebooting to a Ubuntu LiveCD. Does this sound like a more secure idea? Our two other machines are both dual boot with Ubuntu alongside of Windows XP & Windows 7.

Im trying to make a script that will test the suitability of a password. I understand that all the features I want are in the /etc/pam.d/common-password file. From here I can change the length of a password, what characters must be in a password, if the words are in the dictionary, etc... but I don't know how to change these values by using a script. I want it in a script because I want to be able to suggest a more suitable password if the original password doesn't meet the criteria.
View 3 Replies View RelatedI have been forbidden to enable automatic updates on our Ubuntu servers, for both security and regular packages.When I log into any of my four Ubuntu servers, the welcome message contains this:
39 packages can be updated.
26 updates are security updates.
However, when I run the Nagios plugin that monitors APT, I get:
% /usr/lib/nagios/plugins/check_apt
APT WARNING: 33 packages available for upgrade (0 critical updates).
I need to know how to properly detect that there are pending security updates, and regular updates. Once I can do that, I plan to write a Nagios script that will return WARNING for pending regular updates, and CRITICAL for pending security updates.
Is there a way to to check if the system has the available security updates installed? Specifically, I am looking to do this programmatically.

I'd like this distro or config not to be writable and its only purpose being to make financial transactions via a web browser. All other services or applications would need to be stopped or locked down.I've seen some threads on here from a few years back and wanted to know if there is anything new out there that can assist with this.

- Laptop with Ubuntu solely.
- Calibre installed
This post [URl].. by No Bugs! is what has me hoping. Can I install Android: [URL].. Then install the Android version of Overdrive: [URL]..
To get books from: [URL].. with my library card. And install those books on to an eReader (probably Sony505) via Calibre? Not trying to steal the books or illegal download I just want the same "check out" capabilities as the rest of the computing public.
Currently using linux mint.While it's nice I have the feeling all those bells and whistles must be exposing a large attack surface. What is the most secure distro known to man, but which is still capable of making payments to amazon and ebay?

View 3 Replies View RelatedI have Ubuntu 10.04 and I used my ssh to connect to a webserver. This is the version that I have installed.
Quote:
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009
Apparently the server was hacked using my user and the server admin suggested the my ssh can be tainted.
do a checksum of the ssh, but I cannot find this file on my system.
Code:
md5sum /usr/sbin/sshd
And I will need a md5 hash from a good untainted version and I cannot find that as well on the openssh website.
having a slow internet connection, I bought the all maverick repository on DVDs, copied the files on a usb drive and modified the apt sources file to consider the local repository only:
Code:
# deb file:/var/www/ubuntu_local/ ./
deb file:/var/www/maverick/dvd1/ maverick main universe restricted multiverse
deb file:/var/www/maverick/dvd2/ maverick main universe restricted multiverse
deb file:/var/www/maverick/dvd3/ maverick main universe restricted multiverse
[code]....
Even though I am reasonably sure it is safe, this local repository is not authenticated and I can only install package through the command line or synaptic, the Ubuntu Software Centre giving an error message "Requires installation of untrusted packages"...I thus would like to disable the apt authentication check for this local repository.

I was recently connecting securely to the website where I have my mail account, and I connected through Tor. When doing so firefox presents me with the screen saying that the connection is untrusted and it can't verify the certificate. So I cancelled. I'm using torbutton and I turned torbutton to off and connected again with no problem. Then with torbutton on again, same thing (untrusted).
Is it possible the exit node I was going through is doing a man in the middle attack? However later when connecting through tor I did NOT get the warning about the site being untrusted. I really don't know what exit node I was using when I got the certificate warning and what exit node I was using when I did not recieve the warning. I don't know how long I stay on the same node or how/when it changes.

View 4 Replies View RelatedI have set up a user to login remotely to our Red Hat 5 server via SSH. A rule in our department firewall enables this user to login from a single static ip address. The ssh port on our server is 22. I am able to login to port 22 from locations within our department firewall. Our administrator says the firewall configuration is unchanged. The remote user had been successful logging in. But now the remote user gets a Connection Timed Out message, before being asked to authenticate by the server.
I regenerated security keys, but the remote user still gets the connection timed out message. (I can login locally with the new keys). I suspect either a firewall or an authentication problem--inclining a firewall problem. Am I correct? Is there a Linux command to check whether port 22 is available or blocked, prior even to authentication, for login from the user's remote location?
