Ubuntu :: Fix For Virtualbox Key Authentication?
May 20, 2010
Just thought I'd post this in case anyone else is experiencing the same problem. For awhile now, I have been running VirtualBox which was installed by adding the virtualbox.org repository to my apt sources. Starting sometime yesterday, the Update Manager started complaining about key authentication problems, namely:
Code: W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://download.virtualbox.org karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 54422A4B98AB5139[URL]..
W: Some index files failed to download, they have been ignored, or old ones used instead. Apparently VirtualBox 3.2 just got released, and it's the first release under the Oracle name (since Oracle's acquisition of Sun). As such, you need to get a new key:
Code:
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -
Problem solved. I then promptly upgraded to 3.2...

On Ubuntu server 10.10, with a relay smtp server with authentication via postfix; I keep getting 535: Incorrect authentication data. I'm sure my username and password is correct. Heres how I set up postfix: I created a file called smarthosts.conf in my /etc/postfix/ directory that contains the following:

my server uses plain text authentication on port 25. I would like to use security like SSL, but this particular server is unsecured.

If I am running a script, let's say a install script. Is there a way to make Su repeat authentication rather then just returning "Authentication failed" and continuing the script?

I 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.

Observed on two host systems both with openSUSE 11.3 32 bit using ext4: When a big files, in this case a 1.2 GB and a 1.7 GB is copied from DVD, usb harddrive or shared folder into a Windows 7 32 bit guest system, the copied file is corrupted. The md5sum has changed and until the guest system has been rebooted successive md5sum tests on the same file comes up with various results... After a reboot md5sum tests show consistent results, but a sum different from the original file.

I was trying to install VirtualBox through the YaST > Software Management but it is not working, someone in the forum told me that I have to download the OSE version and do it manual way. Finally I am able to start up VB but not able to use the network connection. Thus I am trying to do this:
/etc/init.d/vboxdrv setup. I get this error:
[code]...
When I type dmesg, it shows me a bunch of info which I don't know what should look for. When I type modprobe vboxnetflt, I get the error: FATAL: Error inserting vboxnetflt (/lib/modules/2.6.37.1-1.2-default/updates/vboxnetflt.ko): Invalid module format. what should I do in order to get my VB to be able to connect to the internet?

I am running a small ubuntu-server headless machine at home. It is configured with sshd so that I can connect from anywhere (if I have Internet access.)However, there is a thing: I'd like to have good security and disable password authentication, but I also want to be able to connect from a PC that I've never touched before. And no, I'm not prepared to type a 256 bytes password every time I type "sudo ..."
Here is what I thought: I could have a login (pieroxy) that has a moderately strong password and another user (pieroxy-ext) that has a very strong password (100+ chars.) I would use my regular account (pieroxy) whenever I have a key-based authentication and the other one (pieroxy-ext) whenever I have a password-based authentication to do. Then, I'll just su to "pieroxy" and I'm done typing the 100 chars pwd. In order to do that, I would need to be able to configure my machine so that password-based authentication is disabled for all accounts but enabled for my account that has a strong password (pieroxy-ext). Is it possible to disable password-based authentication on a user basis?

At my workplace the wireless connection is open but once you connect you first need to authenticate on your browser to be able to use the internet.On Windows as soon as I open whatever page I get the login request.On Linux I open firefox but nothing happens, just get the usual error page like if I had no connection. The IP's I get as well as DNS seem ok, I even tryed to match them up with windows.I tried a lot but can't get to the login page.

I have an issue with Adobe AIR, which I use to run Tweetdeck. It keeps on asking me to authenticate for my proxy server - every time Tweetdeck tries to load someone's avatar, for instance, which is making it pretty unusable right now.
I'm not sure why it's doing this, other than that I've just upgraded to 9.10 (well, to Mint 8, actually, but I would think the issue is the same). I've got all my proxy settings working, and indeed AIR seems to be able to read the settings from somewhere (it autocompletes the authenticate box with the correct details), but it just doesn't seem to be able to authenticate once and then be done with it, like it had done previously.

My first post here. I've been using Ubuntu to run our internal mail server for a while now on Ubuntu server 9.04 and ISPconfig 2. I've read a lot of threads on poeple that have difficulty connecting to their server using SSH from outside the LAN and it is not the same problem I have. Well, not entirely the same.
My problem is that my authentication fails from outside the LAn, but I can connect to the SSH port from outside my LAN. The other threads pointed towards checking the router port forwarding etc, but I can see my SSH log in asking for my username and password. So, at this stage I know the port forwarding worked, otherwise I wouldn't even see the log in prompt.
Has anyone see this before where you can connect, but the authentication fails? I can use the correct username and password from inside the LAN, but using the same credentials from outside fails.

I try to install a server based on Ubuntu. It will provide many different services as SMTP, IMAP, Jabber, SVN(via Apache),maybe a groupware and some other web applications.I'm looking for a way of authenticating the same set of users (a user essentially has a username, a domain it is belonging to and some passwords) against all of the services.What is the most flexible and elegant way? I need a method which is not too bloated (mysql or ldap would be okay) and is easily applyable to all those services and all services which maybe will come later.
I've read some documentation about sasl, mysql-authentication, ldap-authentication, pam, cyrus, apache, ... and i'm somewhat confused now about the proper way.For now I suspect MySQL to be the best method for that, but i'm not sure about the flexibility for embedding it into all the services.

I am trying to allow my freshly installed ubuntu 10.04 to authenticate with ldap. I did follow the doc https://help.ubuntu.com/community/LD...Authentication and some other hints with no success.My needs is just to use an ldap existing server (active directory in my site, but i wish to use it via ldap, not via samba/ winbind) to validate users on services using pam modules.After the package installation the command getent passwd retrieve just local users and I don't understand if my ubuntu client is not querying the server or the server reply with some message.

One I cant figure out is a problem of authentication. I'm using open ldap server and try to authenticate a groupware (simple groupware) against it. As it fails, I tested with a ldap client to understand things better. Using GQ ldap client, I 'm able to browse my ldap tree successfully and to search some args from the base DN i specified. but when entering the exact uid as a search string iI got no answer whereas searching the cn returns the correct entry (and display its related entry including the uid I can't find ..) Here is the only thing I can trace in logs (syslog) when trying to seach firstname.lastname (= uid)

I am running Ubuntu 11.04 which I like very much (except for Unity - so I am using Ubuntu Classic).
Whenever I try to use "su - " I get Password Authentication Failure. I have checked Caps Lock (obviously) and have also tried resetting the password using "passwd" - but with no success.
If I use "sudo ...." with a command the password is accepted.
I have the same software installed on two computers but the problem only occurs on one - the other is OK!

su doesn't work in terminal. i found one (click), and tried it, but it didn't fix it. Everything else works. Sudo, Software manager, synaptic package manager... I know i'm putting the right password in. Heres a picture, ignore everything except the last 4 lines.
Everything before it was me trying a proposed fix in the thread mentioned above.
Quote:
sudo dpkg --configure -a
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
I've tried changing my password as well. I got the same error. Also, "sudo su" works fine. I'm not sure if theres a difference as i'm new to ubuntu....linux in general. Can you explain the difference between sudo and su, and sudo su? Also, can you explain what any commands you need me to do are? that way, i'm not just leaching.i'm trying to do is install Java!

On a laptop I have Windows 7 installed, and ubuntu 11.04. Now. A while ago the HDD died and I replaced it. with some data loss but nothing much to worry. Now I thought that it would be useful if I somehow could manage to direct the Documents, Music etc. etc. folders located /home/[user] to somewhere on a different partition HDD. I managed to make new folders on the partition and link them with the documents and music folders etc.. the problem now is is that you have to unlock it every time by either opening the partition and insert your password. I know that the password problem can be evaded by simply changing some settings, but. I want to evade the whole process of clicking on the partition. It is for security reasons that that have to sort of activate the partition, but I find it becoming a bit annoying.
So, has anyone a clue of how to activate the driver right at the start? something automatic stuff. Or does someone know how to disable this ?
