General :: SSH And Stop Password Being Shown In Clear Text?
Jan 6, 2011
I have a headless server running Centos and I often login in remotely to administer it. I have passwordless login and sometimes run commands remotely via ssh from a client machine. I've tried to shut the server remotely but have come across a small problem. Here is the output of the command I use to shutdown :Code:unclec@linux-desktop $ ssh centos 'sudo /sbin/shutdown -h now 'PASSWORD : 123ABCAs passwordless login is set up I do not need to enter a password to ssh BUT as I am running sudo on the server I am asked to enter my centos unclec password and this is shown in clear text on my local machine terminal. Is there a way to prevent this or should I edit the sudoers file on centos so it does not ask me to enter the password when "sudoing" ?

I am using an internal toy svn server, and svn client seems to be configured to store passwords in gnome-keyring by default. How can I disable it or at least switch to kwallet?I am using Debian Testing.

I've been meaning to ask about this since Ubuntu 10.10 launched. How come clicking the "Post message..." text box in the Me Menu doesn't auto-clear the text? You have to highlight the text, press Backspace and then post your message. Not very nice or intuitive. No biggie, just surprised it wasn't patched by someone within a day or two of launch as these things often are!

I'm running openSUSE 11.2 kde on msi wind u123. Everything runs fine except that whenever i try to shutdown or restart system i see both splash background and the rolling text. I think i should only see the splash with the progress bar until shutting down finishes. But for no apparent reasons i see both which is very annoying.
It might help that i changed the splash screen to a custom one. Here is the one i use and i followed every single instruction.

The ubuntu installation came with my ubuntu (it does not matter which version etc.) Contains sshd_config file with this interesting lines:
# Change to no to disable tunneled clear text passwords
#PasswordAuthentication yes
The same lines are seen in many Ubuntu-related internet pages. This is quite surprising to see.
This seem to contradict to the fact that ssh was created specially to provide authentication (with passwords, of couse) but without sending them by internet as clear text like previous programs did. But I could not find any clear confirmations of that neither in Kubuntu-related documents no anywhere else. I put below fragment of a document from RedHat. This seem to imply that if one will use two "yes", the passwords will be passed in encripted form (and this is what is recommended by RedHat). Is that true? Is this true for Ubuntu too? Is the quoted line from sshd_config wrong? Or incomplete?
[URL] RSAAuthentication yes
The option RSAAuthentication specifies whether to try RSA authentication. This option must be set to yes for better security in your sessions. RSA use public and private key pairs created with the ssh-keygen1utility for authentication purposes.
PasswordAuthentication yes
The option PasswordAuthentication specifies whether we should use password-based authentication. For strong security, this option must always be set to yes.

When I'm logged in, physically on the server as root and logout the lines doesn't get cleared like when you logout as a normal user. This could be a bug and if it is, it could be a security problem. The last actions done shows.

RAM: 1GB
Server used as: webserver, database, gaming server.

I installed wine and photoshop cs2. After that Adobe bridge hijacked all my plain text files and shows the adobe bridge workspace icon and Thunar File Manager shows the type as adobe bridge workspace file. It will still open with text editors in the GUI or CLI, but it's still a little irritating.

I've been using empathy to chat on MSN. The problem is I can't erase my password when I want to log off. Theres just one user on this machine, I know it would be easier to create diffrent profiles. But I just want to be able to tell empathy that it should ask my pw to log on to my account.
Is this possible?

I'm trying to install Gnome Nanny [url]
I installed it using Synaptic and when I restart, the Nanny daemon appears to be working.
However, when I try to access to the Parental Control (System - Administration - Parental Control) and after writing my password, it does not shown anything. Nor any windows not any configuration.
I am using Lucid Lynx I386.
Do you know any parental control which could block programs execution (like games, instant messengers, browsers...), could have web filtering and could have spending time control?

we are using linux email server axigen past few years. we keep port open ssh and pop,smtp webmail etc. ssh use for remote trouble shooting. so through firewall it is globally accessable. we notice many attacks coming to our machine, also some people try to enter in our system but failure. as example see below a log come in messages file
Mar 17 09:19:50 sa1 sshd(pam_unix)[21231]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=210.51.13.120 user=root how we can secure more. as per my understanding only good long strong password can stop to prevent from attacks.

I just reinstalled Ubuntu Lucid Lynx and an old problem has come back. For some reason I couldn't fix it even in my previous installation. The problem is the top gnome panel. See the photo below: As you can see, the network icon is not shown properly while the Me menu is being shown twice. I can't even restart or log out or shut down at this situation without pressing the keystroke to turn the power off.

I feel sure there must be an easy solution, but Im damned if I can find it. Im sure I've looked everywhere. Even when Im watching ....., the screen goes dark and when I touch the mouse, Im asked for my password again. It really is very very annoying. I go and make a drink, come back, and there it is again - I have to type my password again.

Whenever I turn on my computer, asks, (after I enter my login password) for the password for my "default keyboard settings" (or something like that) 4 times and my WEP 128 (whatever that is) password. I just hit "cancel" or the little "x" in the corner, but it's a bit of a nuisance to do it each time I turn on my computer.
How do I get Ubuntu to stop asking me for my password for so many things?

I'm the only one who uses or has access to my computer, so I don't need the password security that others might. Frankly, it pisses me off to have to enter my password every time I leave the computer for a few minutes, or want to make the many tweaks that are necessary to get a system going, whether it's installing software or anything else. How do I stop it?

I recently set up an Ubuntu computer for a friend who is new to Ubuntu and who is complaining that very often, Ubuntu's Update Manager pops up and asks for password to install updates. How could we make the Update Manager install updates quietly in the background without interrupting and asking for password? Maybe this should even be set as default in forthcoming versions of Ubuntu!

I've set up a Lucid system with software RAID and encryption, with three encrypted partions - swap (/dev/md1), the root filesystem (/dev/md2), and /home (/dev/md3). The unencrypted /boot partition is /dev/md0.
This works well but the passphrase had to be entered three times at bootup. Obviously it would be preferable to enter the passphrase once to unlock the root partition, then have the others unlocked via key files. So I added key files to the swap and home partitions and modified /etc/crypttab to use them:
Code:
md1_crypt UUID=8066adbc-584c-4766-b188-bc2a7b61a2f0 /root/keys/swap-key luks,swap
md2_crypt UUID=bac82294-f3b9-45e4-89ad-407cf8b19b7b none luks
md3_crypt UUID=7d82a0b7-c811-4cc3-9fe7-1961c74b5ff2 /root/keys/home-key luks
The key files are owned by root and have 0400 protection. (The /root/keys
[Code].....
Since the swap partition is no longer referenced in fstab or crypttab, why is there still a bootup password prompt for it? What else needs to be done to stop it?

When I installed Ubuntu (Lucid) on my new computer, As well as the login password I was asked for a keyring password. I gave one, but I am not sure exactly why I need this password. It seems that it was required to let me access the wifi - even though this has its own security code. I found I could stop the system asking for it every time I tried to connect to the internet using wifi by checking a button in the network setup, but when I registered for Ubuntu One, I was again asked for it - twice, once when I registered and again when I set up Tomboy notes sync. Now I get asked for it again every time I switch on.
I would like to know why the keyring passwords are needed in addition to the login password for a single user computer, which mine is and also how I can stop it asking for this password when I switch the computer on. One suggestion I have seen is to make the keyring password the same as my login password. If that is the case, then how do I change the keyring password?
