Can't seem to do it, wondering if anyone knows how? Normally there's something in sshd_config that can be switched to true or yes to allow root login but I can't see it in fedora 12.I can login via root at a terminal no problem, just not via ssh, I get access denied every time. Also, I need to login using password authentication.I've done: 227169 but that's just for GUI which I don't really need since I rarely ever log into the GUI.I have also searched through here and mostly only found info such as above, how to enable root login for GUI, or billions of posts about how logingin as root is bad but I cannotswer to my question.DISCLAIMER: Please do not reply to this thread if all you can contribute is the question of why I need root or to put some message telling me I can do everything using su, etc, etc. Please only contribute if you can answer my question. A: My machine and a valid quesiton. B: Spirit of Linux is open, not restrictive

I want to secure this using a logon page.allow login Only for the successful authentications by entering the predefined username and password But after get authenticate book marking the above URL still can access anyone since it didnt prompt username and password again In eachtime executing the above url it should direct to authenticate page
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.
I have a rather difficult problem. Every time I need root privileges and I am asked to authenticate (i.e. Update Manager, mounting a partition, etc), the password window comes up, shakes and immediately closes, leaving me with no chance to enter a password. What to do?edit: this is NOT the login window, just the little dialog that pops up when you need elevated privileges.

View 3 Replies View RelatedI 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?

View 2 Replies View RelatedI 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!

View 4 Replies View RelatedI know this has probably been asked too many times here but I need to secure my emails. Personal matters of course. But yeah. I use the program "Password and Encryption Keys" to generate a key to sign my emails with but I do not know what to do. To be blunt, I'm stupid when it comes to this. IF not, steps in creating a key? and giving it (my public key) to the significant other? Finding where both keys are? Implementing it into Thunderbird? If it helps any here's some extra information: Ubuntu distro: Ubuntu 10.04 Email client: Thunderbird

View 6 Replies View RelatedI've been using the Ubuntu desktop for a couple of years now, but I don't have much experience using the terminal.
I've just set up a home server using Ubuntu-server 64bit which will be headless and its main function will be a Mythtv backend.
I've worked out how to use VNC to send a desktop from the server to my laptop, but when I try to use any programs which require root privileges such as synaptic or the user/groups manager, the pop-up asking for authentication refuses to accept my password.
Is there a setting I need to change on the server which prevents remote users from getting root privileges on the desktop?
I have a weird problem with ssh, I am trying to ssh to a solaris server (sparc) running solaris 10 from my Ubuntu box and as soon as it authenticates the password it closes the connection. The box is located on a internal network in a wiring closet with no ability for me to access console but i still have a working ssh session from 2 days ago with what i'm trying to comb through settings and trying to resolve the issue. It also has 2 NIC's and I cannot connect to the either ruling out hardware problem. I checked if there is a limit of the number of active connections and the was no limit. I was able to connect mitiple session till 2 days ago (at one point i had on my machine 8 active ssh sessions to the same server).

I recently upgrade to Fedora 14 from 13. It was an in-place upgrade. I can't recall for sure, but I do believe I had these problems in F13 before the upgrade. The F13 install was from a Live CD. Anyway, I have a three drive RAID 5 array setup - 3x 750GB. For some very annoying reason, each time I reboot my F14 system, it hangs with an error about not being able to find a superblock on /dev/md126 and /dev/md127. I have tried to stop and remove /dev/md126 and /dev/md127 but they always seem to come back. I have also noticed in the output of fdisk -l that drives sda and sdd like to swap places sometimes for an unknown (to me) reason. Any other output that is needed, please ask. I recreated the array just yesterday with:
Code:
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1
I would cat mdadm.conf in /etc, but I removed it previously to try to figure out the problem and it was not

View 5 Replies View RelatedPAM time restrictions - changing Time.conf so it gets time from a sql table. I was wondering with the PAM authentication module (pam_time) that I can grab time from a server using sql/postgress which uses TIMEDATE function to get the time of logging out into pam_time? So basically I want to insert sql statements into Time.conf which would get the time from a table.
View 1 Replies View RelatedSo after tinkering for a while, I was able to configure ssh for private/public key authentication and disabled Password-Authentication.

View 2 Replies View RelatedI have a Ubuntu 10.10 installed on my HP Mini 210, and is having a problemth authentication dialogs when applications requests for elevated permissions. As far as I concern, there are two types of them, one is the kind when you run anything with gksu where the background dims and a dialog pops up. Another type is when you try toinstall software through Synaptic and a dialog box requests for your password. I am having problems with the later one.
Whenever the authentication dialog box pops up, after typing my password and presses enter, or the Authenticate button, the password field disappears while leaving the authentication dialog on the screen. The Authenticate and Cancel buttons are still clickable, but they are not bringing any actions by clicking them. I would have to let the application to continue with elevated permissions by manually closing the dialog. There are very very rareoccasions where the dialog disappears after I click on authenticate, which I can say is 1 in every 100 times
When I am upgrading, installing something or doing something that requires me to be Authenticated by using my password I just type it in and hit enter. However, each time I just click return after typing in the password it does not work. The window accepts my password but thats it and the window just sits there until it times out a few mins later. For this to work properly I have to type the password and then use the mouse to click the Authentication button. Why is this? Is there a way to solve this so I can just type in my password and click return like I do with everything else?

Then it stopped working and i can't make any changes because i don't know what word the blasted system wants. Am i locked out forever? Should i re-re-install v10 and everything else? or how i can change my authentication password without knowing what the computer wants?
View 9 Replies View RelatedI have installed Ubuntu 8.04 inside windows and every time I go to the terminal and type "su" it asks me for a password. Well the password I set before the install doesn't work, it gives me an authentication failure. I thought that since it was inside windows it didn't set me as a root user. I go to user groups and I see my name there and then "root" above it, but its grayed out. Is there a default root password I can enter?

View 6 Replies View RelatedI am trying to set up remote login via SSH from my Mac to an Ubuntu desktop. Here is the error i am getting:
Code: Permission denied (publickey,password). I'll give background:
- Both computers are on the same network
- I'm not using the default port 22
- I have successfully logged in using password authentication, so it isn't a firewall/iptables issue i don't think. I've already worked through those issues!
- I haven't set up any tcp wrappers on the server yet, so nothing is being denied
- I believe the server sshd_config file is setup correctly. I can post it if needed.
