Ubuntu Security :: 9.10 - SSH Askpass Dialog Missing
Jan 13, 2010
I have 9.10 at work and at home. At home it was installed from scratch. At work it's upgraded from 8.10->9.06(?)->9.10
- At work, when I do something over ssh, like subversion, and I have a key for that host, i am presented with a nice dialog box for my ssh key. and that's it. for the rest of my uptime, i can ssh to places without any hassle.
- At home, I'm presented with the key input prompt on the terminal. Even If I manually start ssh-agent, it still happens.
What package am I missing? I have the ssh-askpass-gnome on both.

how do I make ssh-add use ssh-askpass-gnome instead of default ssh-askpass? System is OpenSuSe 11.3, both packages installed.

When I write the command "sudo apt-get install dialog". I get this:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package dialog is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package dialog has no installation candidate

I am running an Ubuntu Server 10.10. I have installed Apache2, I put my perl script in /var/lib/cgi-bin. When I run this perl script from the terminal it works fine. When go to a web browser it doesn't. When I look at Apache's error log, I see this line :"sudo no tty present and no askpass program specified"I tried editing the sudoers file, with the user www-data ALL=(ALL) NOPASSWD:/path_to_my_script. But nothing changed. What am I doing wrong?

I have a problem with Opennebula that I have been trying t o solve for weeks, I have tried many options and have got nowhere. I have two HP ML115 servers configured to act as opennebula cluster nodes named opennebula01 and opennebula02. I have also installed the Front-end opennebula management deamon on node opennebula01. To use opennebula I have created a paswordless oneadmin user which seems to be ok because I can ssh to localhost and both nodes without a password. Using the onehost command I have created two hosts both tehse hosts are running correctly.
See Example1.
Periodically the opennebula monitoring system will fail, the problem I am having is that the logs keep showing the message:
"sudo: no tty present and no askpass program specified"
See example2
I have used the visudo command to change the sudoers Defaults visiblepw option but I just get a "root's password:root's password:sudo: pam_authenticate: Conversation error" error.
See Example 3 and Example 4.
Example1
========
oneadmin@opennebula01:/srv/cloud/images/ttylinux> onehost list
ID NAME RVM TCPU FCPU ACPU TMEM FMEM STAT
0 opennebula01 0 0 0 100 0 0 on

I seem to be missing a secure.log or security.log file. I have Ubuntu 10.04 and can't find this file. I looked in the /var/log and ran a search command to no avail. Does anyone know where this file is or is it called something else. I'm looking for a file that logs any change to the security settings of the system.

In Ubuntu Customization Kit I get this error: sudo: no tty present and no askpass program specified So, I read up and found I could try oem-config-remaster which I installed through the USC (Ubuntu Software Center). I couldn't find the software in any menu so I tried to open it through the terminal. Here's the intel:

I am doing a honeypot project, and after I install nepenthes: $ sudo apt-get install nepenthes
$ nepenthes
I find that there are no configuration files in /etc/nepenthes/, and only a signatures document.
I searched in the internet, all the install guides do not mention this problme, just say that if updating the nepenthes, the /etc/nepenthes/*.conf will not automaticly update.

I want to monitor a part of my filesystem for changes, including file opening and attempts to open files/dirs without necessary permissions.Since every read/write/open is run by syscalls i figured that running the auditd would be the simplest way to do this. I installed auditd and added a rule:
Code:
auditctl -w /srv -p warx
However I do not get any writes reported via ausearch -i. As a simple example, if I run

CentOS 5.6 Server patched to latest, multiple name-based apache virtual hosts. SELinux OFF Everything was working fine until the other day. I've been making quite a lot of changes so it may well be something I've done, but I can't find out what! Last night I got the following in my logwatch : -
Requests with error response codes

The problem is that NONE of my logs, secure, httpd, messages, NONE of them, show any trace of these hacking attempts. They used to show up in secure and apache error logs, but no longer.

I installed Startup Manager but the appearance and security tabs are missing. I really want to be able to change the resolution of the splash screen cause it looks all pixelated and I want to have the splash screen that 9.10 had.
I tried reinstalling and restarting but the issue remains. I know its somewhat functional because I am able to change the seconds that grub takes but when I try to change the resolution of the purple ubuntu startup screen it looks like it tries to change it but it fails.

I have now been trying to find an answer for the following for a while and can't seem to get anything.On previous linux distros we had the option available "passwd -e" which allowed us to force the user to change their passwords upon the next login.s functionality however seems to be excluded from latest linux distros (currently using RHEL 5.4)...Does anybody know how the same effect can be achieved and perhaps any idea on why this option was removed as it was great for securing passwords

I am having trouble starting up Ubuntu (Karmic). Bascially I get to the bit where the log in dialog is supposed to appear, but it doesn't.
Is there a hot key of some sort to force the login dialog to appear?

When I use a little helper window (like the find and replace dialog) in OOo 3.2 on 10.04 UNR it always comes up maximized, which is kind of irritating, because I have to restore it before it's usable. It's weird that such a window should even have a maximize button, but there you go. No biggie, clearly, but if anyone knew of a workaround that would be great! I'm using the clearlooks theme, although I tried with the new black shiny one and it seems to exhibit the same problem.

I am a total novice to Ubuntu OS. I am running 10.10 on a Eee PC 4g.
Some dialog boxes are too big for my monitor. I have tried re-sizing using mouse's middle button but there seems to be a limit to the amount you can reduce, which leaves them still too big??
I have hidden both top/bottom bars.
I am prevented from setting up a wireless connection. 1. Because the 'Editing Wirelss Connection' box/window is too long to be able to click apply?? 2.Because all the tuts I find are for older versions and don't seem to apply now?
I starting to think maybe Ubuntu is not for me, I am not a programmer?

How do I open an app from a dialog box? Eg the download db in FF in which you have options to Open or Save. I want to be able to navigate to a folder containing app folders which I can then open to find an icon to double click so as to launch an app. Much like in Windows navigating to Program files (I think it is called). How do you do this in Linux?

the application that is giving me the most grief, as far as the dialog box being over-sized for the screen is KDE BasKet - how do I adjust it?

On 8.04 when I connect to the internet for work, it normally asks me for proxy authentication. When I type in the correct credentials, it allows me access to the web. For some reason, when I use 10.04 to access the web via firefox or chromium, I do not get the proxy authentication dialog box, so I cannot access the web.

My girlfriend has a Toshiba Satellite Athlon64 laptop, and she can't get it to go past the user list dialog before it logs all the way in. We've tried her username and password, but every time we enter it, the screen blanks for a moment and then returns to the user list dialog. I've reset the password by booting to terminal, but it still won't let us past the dialog. I'd hate to have to reinstall her system. Is there any way we can get past this? And, why is it not accepting the password? I couldn't find an open bug on this issue.
Also, we had just installed OpenShot Video Editor during the same session. She said she got it from the Synaptic Package Manager. I'm not sure if this messed with her video settings. We can see X trying to start after we put the password in, but it keeps going back to the user list dialog. Actually, I uninstalled OpenShot and gnome-screensaver from the root prompt, just in case they were causing the issue. I had noticed that the laptop was buggy coming in and out of hibernation. I wonder if that's causing X not to start properly? I did check the startup logs and I didn't see any errors there either.

I can't seem to run Evolution. Whenever I try to open it, I get a box asking for the password for my email account as well as a box asking whether I want Evolution to be the default mail client. The answer in either box is not acknowledged, and the only was I can figure out to close it is to "killall evolution". I'm having a hard time searching for bug reports--nothing seems to come up with the terms that I have used.
How can I reset this? I kind of want to try out the Contacts manager feature and the MS Exchange compatibility, but I use Thunderbird for my main email and I don't want Evolution to be the default. Incidentally I'm actually using Fedora 13 but I imagine most of the commands I might need are the same.
