Is there a way to disable password authentication completely? The command line is the following:
ssh -o KbdInteractiveAuthentication=no -o PasswordAuthentication=no machine"
it STILL asks for a password. Of course I would like to do this without touching the server, if possible.
I set up a debian lenny in vmware on my windows machine. The network interface is set to bridged, so the virtual machine is connected directly to the university network i am connected to. I want to be able to ssh into the vm.I installed sshd via "apt-get install ssh", generated a key pair with puttygen and copied the public part to "/home/user/.ssh/authorized_keys", set rights to 600 and then tried to disable password authentication completely, following the "securing debian" documentation.this is how my /etc/ssh/sshd_config looks now:
# Package generated configuration file
# See the sshd(8) manpage for details
# What ports, IPs and protocols we listen for
[code]...
I have a problem with ssh.I followed this guide:and no matter what I try, I still can't disable password authentication. I want users to require a private key to prevent from brute force hackers.
View 6 Replies View RelatedSo after tinkering for a while, I was able to configure ssh for private/public key authentication and disabled Password-Authentication. In the past I had some issues with people brute force trying passwords/usernames so I want to avoid this, but I need some form of secure FTP that now doesn't work due to the aforementioned setting.

How can I edit the files present in the patrician filesystem?
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.

I think in previous version there was an option in one of the System->Preferences->Appearance dialogs to enable 3D effects partly fully or not at all for GNOME 2. However, I cannot find this dialog any more in version 11.04. Where has it gone?
I would like to make sure that all 3D mumbo-jumbo is completely disabled with ubuntu classic.
Is there any way to disable password masking in Linux - specifically Linux Mint 9?
Ideally I'd like to be able to choose whether to mask or unmask password fields on-the-fly, as is possible when entering passphrases in TrueCrypt.
Sometimes masking is useful (say, on a laptop in public), but often it's totally unnecessary - there's no-one looking at the screen but me, so there's no point to it.

I've got 5 users who share a bunch of virtual Windows XP guests via VRDP (VirtualBox RDP access), and I'm having some problems with managing their NumLock state. They all use rdesktop to access the Windows XP machines. This works very well, as long as all of them have NumLock enabled. If one of them disables it by mistake, and then logs into one of the Windows XP machines, NumLock is disabled and some of the programs they use start to act really weird. This is causing us some grief.
So I'd like to be able to enable NumLock on all the computers (they are all running Slackware 12.2) before X, while X runs and while KDE is running. And when NumLock is enabled for the entire system, thenI'd like to remove the ability to disable NumLock altogether. NumLock should always be enabled for these users, no matter what. It would be really nice if Linux/X/KDE/whatever just honored the BIOS setting, but I haven't been able to figure out how to do that. Oh, and I'd really like if the NumLock LED was ON, so everybody are made aware of the fact that they have NumLock turned on.
ps. I've tried remapping the keys on the numeric pad with xmodmap, but that doesn't solve the problem. The actual NumLock state must be set to avoid problems with the troubled Windows programs.

View 5 Replies View Relatedhaving 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:

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 am trying to download programs from the Ubuntu software Centre and keep being asked for an authentication password.The only passwords I have are for this site, default keyring and the terminal. How do I set up this password and where?
I have found the answer. It is my Terminal Password that is required to enter the Ubuntu Software centre.
I'm dual booting Ubuntu 9.10 and win7. I have an NTFS partition on my disk and whenever i want to browse files on that partition I'm required to enter my password. my problem is that my music folder is located on that partition, and as a result, whenever I open rhythmbox, it cant access the files on that partition and begins to remove them from the library. in order to prevent this i must browse to that partition manually and enter my password upon request, prior to opening rhythmbox.
on a side note - shouldn't the spell checker on the Ubuntu forums recognize "Ubuntu" as a legit word ?
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?

View 2 Replies View RelatedI am running Ubuntu 11.04 which I like very much (except for Unity - so I am using Ubuntu Classic).

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!
I was hoping that someone could point me in the right direction. I just did an install and the os is up and running. During install, I set a root password and also set up a regular user account. The only option at login is the regular user acct. Needless to say, the os asks me to provide the root pw for just about everything I need to do.get an authentication failure. (I assume that this is the same as permission). I can find plenty of info on how to restrict access but nothing relevant to my problem. Just to rule out an install problem, I installed the os a 2nd time. I am very sure I have my passwords correct. One other thing to note is that on the 1st install, I used a different pw for root and regular user. On the 2nd, just to keep is as simple as possibl I used the same pw for root and reg user account. I am new to debian, but the distro that I have been using (slackware)

I'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?
