Ubuntu :: SSH Without Password Not Working With Keys
Dec 21, 2010
I have two machines at home. I am trying to setup the ssh server on the server machine so I can connect from the client machine with no password (keys authentication).Well, that shouldn't have been too hard, but the thing is the server user account I want to be able to connect to with keys auth has no password (that is actually the reason I want to setup keys auth). I have done everything in this guide (URL...), both alternatives, but with no success, because at some time I have to ssh the server to the user account that has no password (either with scp or ssh-copy-id) and it fails.
My question is: since I have root access on the server machine, can't I copy manually the public key from the client to the server? (doing manually what ssh-copy-id actually does).Or, maybe there is another way, to change the password on the passwordless account. I have tried with # su <acct>, then passwd, but it doesn't work (asks me for the old password). I was thinking about editing /etc/shadow manually, and inserting the hash in the password field for that account (it currently has an ! ). Would that work?

I 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

What is the easiest way to encrypt plain text content with a password only? I need to encrypt client login information, but I hate dealing with all the unnecessary complexities of Linux's encryption systems.
I know I am going to get a bunch of people telling me how perfect Seahorse and whatever is, but Seahorse and the default /home directly encryption have both given me too many problems when decrypting my information. I prefer to preserve my data rather than using these methods.

I want to ssh, scp, git fetch, etc. without a password. I saw the previous questions, and closed ones regarding this issue, but the suggestion seems to be to use ssh keys. However, after setting up ssh keys, I am still asked for my password (it's not asking for my private key password; it's asking for my login password). How am I supposed to set this up so that it only uses my private key for authentication?

I thought these were the same password?In-fact, they WERE the same password on the set-up I currently have.But now, weirdly, I can log in fine but I the exact same password is not using in order to perform admin tasks.I've tried a recovery mode, console, and then "password (username)" in order to reset the password.This does reset the password I need to use to log in, but the password still does not work for performing admin tasks

My setup is Asus EEE701SD running Maverick installed off the Live CD about 6 weeks ago. Everything worked fine until yesterday when I lost most of the keys, but not Ctrl, Alt, Home symbol, Menu symbol.
Keyboard is physically fine as it works correctly in SystemrecCD and when I boot into a recovery root shell, but not when I am running Xorg under Maverick. Keyboard layout is default US (I an in Australia). I tried using Onboard, but even that wouldn't input keystrokes into anything. I tried going in with VNC and that wouldn't work either. It seems this might be an Xorg problem, but why would it happen suddenly, seemingly without any provocation; obviously something has changed, but what... I have removed and reinstalled xserver--xorg using apt-get in a root shell and have also run dpkg-reconfigure xserver-xorg, but nothing has changed.

control keys aren't working most of the time in Open Office. I can copy, cut and paste with the mouse, but Control+C/X/V/Z is not working at all. I also use intellij idea, there I have the same problem, but I can use its own defined control+alt+space. I've tried Abiword, the control keys worked at the begging but then after a while when I used control+something(C/X/V/Z), it always selected everything. Besides that, the control keys are working perfectly in nautilus, terminal, firefox, chrome, gedit. I'm using Ubuntu 9.10.

After upgrading to Lucid, Mouse Keys started working erratically. For example: If I keep pressed the 4 numpad the pointer doesn't move, however, when I press 5 the click happens where it should. In short, the mouse pointer doesn't reflect MK's movements.

On the mbp 5,3 running 10.04, I'm trying to get the screen dimming keys working. Using the tutorial [URL] I followed the instructions for the nvidia-bl-dkms package. Initially upon configuration, the dimming keys work wonderfully, but after a restart, they don't work at all.

I have a Lenovo G550 Notebook, with a US keyboard layout (dedicated Numpad on the right). Now the quirk is.. the 'Home', 'End', 'PageUp' & 'PageDn' keys on the numpad do work in Ubuntu (They double up as 7, 1, 9 & 3 respectively, when Numlock is turned on), but what doesn't is Shift + 'Home', 'End', 'PageUp' or 'PageDn'.. Is there a setting to do this? I just have gotten used to it in Windows (for say, easily removing the typed in URL on a web-browser, using the keyboard), it seems like alls' lost without it

The keys were fine till yesterday and suddenly they have stopped responding.

I'm having problems with open-office writer. back-space end all other navigation keys refuse to work...delete works fine. system runs Hardy Heron and o-office 2.4.1The problem only applies to my profile, what files should I look for concerning keyboard config? Methinks Gnome and KDE frontends kinda conflict when assigning layouts to the keyboard, but that's just my own rambling

When using nano in the terminal, I can't seem to navigate text using the arrow keys - everything I have read about nano says I should be able to do this.
My Ubuntu installation has no GUI, so I can't use the mouse for navigation.

The function keys regarding the brightness do not work on my laptop. I am using Ubuntu 10.4 Lucid Lynx LTS 32 bit version. I've looked on the internet for help regarding my laptop but I cant find any solutions regarding the brightness function keys for my laptop Sony Vaio VGN NR21S. The graphics card in my laptop is NVidia Geforce 8400M GT.
I've tried writing brightness-up and brightness down scripts along with a bash script but even those don't work. I tried Gnome Power Manager but that didn't solve any issues. The wireless and sound functions work.
Are there any solutions available for this particular laptop model?

I just bought an Apple (intl.) keyboard because of its stylish look and weight but I can't figure out how to map keys to get certain functions that I'm used to working.
Particularly Alt+Ctl+F1~6 when wanting to switch to regular terminal and print screen.
Is there a tutorial out there that explains how to map keys?

I'm having trouble with dead keys in Emacs on Ubuntu Lucid and I'm at my wits' end. Using a standard Norwegian keyboard layout, and dead keys work fine in all Gnome applications. But Emacs just spits out messages about undefined keybindings when I use dead key combinations, for instance for tilde (~): "<dead_tilde> is undefined". This is super-annoying, since I use Emacs a lot, and I need some way to fix this.
What I've tried so far: Loading the 'iso-transl' library in Emacs seemingly makes the dead keys work, but it's not consistent across modes (works for plain text, though), and I didn't need to do this before. Also, loading this breaks Emacs' latin-1-prefix input method, for some reason. Fiddling with keyboard-preferences, iBus, im-switch xim/none/ibus, etc. Removing ~/.xinput.d directory. Fiddling with various environment variables: GTK_IM_METHOD, GTK_IM_MODULES, XMODIFIERS
Of course, I'm testing this in Emacs started with '-Q' to elminiate problems that might be caused by my own rather extensive set of initialization files. Using dead keys in Emacs has never been a problem until I upgraded to Ubuntu Lucid.

I'm using Ubuntu 9.10. All of a sudden several of my function keys stopped working and several keyboard shortcuts that I had setup involving function keys stopped working as well.
For example, when I go to preferences->keyboard shortcuts and try to set "Toggle fullscreen mode" to Alt+F11, the text "XF86AudioRaiseVolume" appears where it should just say "Alt+F11". Pressing Alt+F11 does nothing.
All of my function keys somehow got mapped to XF86AudioBlahBlah and no longer work. How do I undo this? I recently installed ffmpeg and gtk-recordmydesktop but I don't think I installed anything else.

I could find on the net to fix the screen brightness keys and get them working so I could increase the screen brightness. Nothing worked.For most or many people, some of the suggestions will work fine. For those of you who can't get them to work and are stuck with Ubuntu 10.04 on the NC20 with a dimmed-out screen, I have a quick workaround:
When you boot and get to the BIOS password prompt, use the function and up-down array keys to control the brightness there. The screen brightness will be carried through to Ubuntu. You might be able to do this at the GRUB prompt. The point is that the BIOS handles the screen brightness before Ubuntu, so it just works.

Today I did the following:
Code: Select allapt-get upgradeapt-get dist-upgrade
After a reboot the multimedia keys are not working anymore.
Also Code: Select allxev doesn't give any output when pressing the multimedia keys.
I've also checked the packages that were upgraded, but none seems (to me) to be changing anything in regard to key events.
Code: Select allStart-Date: 2015-07-29 09:17:10
Commandline: apt-get upgrade -V
Upgrade: libasan1:amd64 (4.9.3-2, 4.9.3-3), gdisk:amd64 (1.0.0-2, 1.0.0-3), cpp-4.9:amd64 (4.9.3-2, 4.9.3-3), libstdc++-4.9-dev:amd64 (4.9.3-2, 4.9.3-3), libpanel-applet0:amd64 (3.16.1-3, 3.16.1-4), python-debianbts:amd64 (1.12, 1.13),
[Code] ....
I'm on the Debian testing branch. Initially I used xfce, but am now using i3.
Why there are no events after the upgrade? Maybe I should downgrade some of the above packages?

I just installed fc12 on a Dell Latitude E6500 laptop. Everything is fine except that my Left and Up arrow keys are inactive so .e.g. I can't review bash history.
In the "keyboard preferences" GUI the keyboard model is "evdev-managed keyboard" (although I have also tried without success the model specific for this laptop) and the only layout is "USA".
Have done an update of all packages without fixing this problem.

I have searched the web read every post and still i cant seem to get dual monitors working correctly. I have a notebook and a extra external screen at home. Here is my issues
1) My Desktop background stretches over both screens.
2) My Display seems to think I have dual monitors attached permanently.
3) fn + F4 only blacks out screen for a few second.
get this sorted so that when I plug-in the external monitor it works and when I unplug and reboot it goes back to one screen
