It seems like to me.. Fedora 13 has a longer update interval than Fedora 12.. I remember back in Fedora 12 I get security updates like every other 12 hrs.. (I know as with security patches the less the "better"(in some way))..
But I am still concerned.. security updates has been slow for me.

View 1 Replies View RelatedI need to make a choice on what authentication protocol I want to use for Authentication and Authorization. I was looking at Radius and then literature suggested that Diameter was a better protocol. Keep in mind I need this on a hetrogeneous setup ( linux & windows together). Diameter seemed like a good fit until I discovered that the open source code no longer seems to be maintained ( C/C++).
I was also looking at Kerberos as an option though there is alot overhead with the server. SSL/TLS or EAP? I am looking for simple but secure and am new at the security protocols.
So, it is my understanding that Ubuntu's automatic updates do not install ANY updates that are not "important security updates." For example, it did not upgrade me to Firefox 4 automatically; I had to do it myself (Don't all new browser versions usually contain new security features/patches? Oh well...That is a separate question entirely).
ANYWAY, is there some way to get the latest stable versions of all of my open-source software automatically (or at least all at once, on command), instead of just security updates? It seems silly to have to install new versions for every program manually.
Also, related/side question: Now that I have installed Firefox 4 myself (via apt-get by adding the mozilla-stable PPA), will I stop getting security updates for Firefox through the standard Ubuntu update manager?
Actually, a really thorough explanation of the whole automatic update system (or a link to one) would be great too.
There is a problem with dependency resolution for the recent updates; i can't update my system even with the skip-broken, there is something to nautilus and phyton-devel and phyton, pls, take note of these.
View 3 Replies View RelatedSo 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?
View 9 Replies View RelatedI'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?
With an Ubuntu 10.10 upgraded from 10.04, under Software Sources, Updates, there is a radio button marked "Install security updates without confirmation." I have this radio button marked, but still get "Important security updates" almost daily in my update manager. I don't remember this feature actually ever working.

View 3 Replies View RelatedDoes anyone know when we'll see Firefox 3.0.19 packaged for 8.04 LTS? I'm still stuck at 3.0.18. And what will happen after this? My understanding is that after .19 Mozilla is dropping support for FF 3.0.
Upgrade policies not withstanding, I find it rather annoying when an "LTS" release doesn't keep up with the most security-critical package in the distro, the browser. 8.04 LTS should have moved to FF 3.5+ a *long* time ago. Now it seems it will be forced to do so or else just forget about browser updates for the last year of 8.04?
I know I can install the current Firefox with ubuntuzilla, I just keep wishing Ubuntu would do it for me.

How can I remove authentication completely from my pc?
How can I edit the files present in the patrician filesystem?
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.
Does anyone know if/how its possible to integrate HOTP authentication into GDM login manager? Basically what I want to do is have it ask for the password of the account, then another prompt come up asking for the code for the account.
I know how to set it up, but I'm know if modifying the PAM module for requiring OATH/HOTP authentication will make this happen or if it will just break the system...and this is one thing I don't want to have to fix.
Given that my public key is a pre-shared secret is sshd made in a way that this negates the possibility of a man in the middle attack? In other words, if the known_hosts file were to be deleted, would it be safe to ignore the fingerprint of a server that already has my public key in authorized_keys?

I'm working on a work project related to Web (Client) authentication and DOD Common Access Cards. But I'm having difficult getting the details about what happens on the CAC side of things.
I familiar with the PKI system as it applies to e-mail. (Correct me if I err, of course.) If you want to sign an e-mail (i.e., so it can be authenticated by the receiver) you use your private key to add a digital signature to the message. Then, the receiver uses your published public key to determine if the digital signature is valid, i.e., was created using your private key (even though the receiver never actually has access to your private key).
So... my questions:
1) When a person with a DOD CAC visits a CAC-enabled web site, and the server grants access after the CAC is inserted, is the authentication process fundamentally the same as what happened with the e-mail authentication?
2) If the private key is used in this process (it would have to be, correct?) is the signature created on the CA Card electronics (i.e., the private key remains on the CAC)? Or is the private key copied onto the computer, which uses it to create the signature?
if you go to Edit > prefs > security and choose to show saved passwords they are displayed without entering root pw. This seems to be a huge security hole. How do we fix this?
View 8 Replies View RelatedMy server is connected to the Internet for ssh on port 22 with root logon disabled, a single non-dictionary word user name allowed, and pki authentication only (about as secure as I can make it). I've previously run fc5 and 9 servers using the same sshd config since 2006 and had no security troubles, so I'm happy, but.. After the fc13 install and configuration, logins from a host on a remote network are taking about 1m 30s to complete! A (partial) console output for ssh -vv appears below. The lines marked with "**" were the lines after which significant pauses happen. This is fully repeatable.

I want to use AD sys accounts to logon to linux servers. What is the best and most secure way to do this. This because we want to ensure it is tracable when a server administrator makes changes to a linux server. Now we use root to make changes to the servers.
