Ubuntu Servers :: Sudo No Longer Prompting For Password / Resolve This?

Aug 16, 2011

I am suddenly not prompted for my password when I run any command as sudo on a few of my Ubuntu servers.

if I run sudo -K, the session is cleared, and I am prompted again for my password, however it saves/caches it until I run sudo -k again even if I log out and back in. I want it to prompt me for my password, as it should (and did) by default, for security.

Any ideas what could be causing this?

Here's my /etc/sudoers file code...

I have 4 servers that I got at auction and they now have ubuntu running with gnome interface.I installed apache2 and tried to edit the conf file but i am not sure if it is a router issue a dns or the config.I am trying to figure out how to set the server to hold the domain from a dynamic ip address and also how to create some test page to see if i can acess from the internet.

I have purchased some books on the command lines and how ubuntu works, I am understanding it so far, but dont know how to have a directory for the dns request to point to for the sitewhat i want to do with the servers...voipeb server for about 4 websites - one is for a volunteer rescue organization, another for a test auction site and 2 portfolio sitesremote file access- if possiblealso on a side note, is it possible to have a message relay from one cell phone or transmit to the server and have it send sms message to cell phones? - this will be used for the rescue group as well.

Ubuntu :: Sudo Doesn't Keep Environment Variables

Jul 19, 2010

When I execute something with sudo, the environment that it executes in doesn't have all the environment variables from /etc/profile{,.d/} defined. I googled around and found that there is a way to get the environment variables from the calling environment to be carried over to sudo's own environment, but that's not exactly what I want. I just want sudo to read the /etc/profile and /etc/profile.d/ before executing commands.

Ubuntu :: Can't Run Firefox - Thunderbird Without Sudo / Resolve This?

Jan 19, 2010

I just migrated into Ubuntu 9.10 from Windows and moved my mail profiles and also my bookmarks to Thunderbird and Firefox.

I can't see the Mail profiles and messages unless I run "sudo thunderbird" and I can't save or edit bookmarks in Firefox unless I run "sudo firefox".

Probably it's best if I don't run Firefox or Thunderbird as root, eh?

I've tried changing the file permissions for bookmarks.html, but no luck. And haven't even tried to tackle the Thunderbird issue yet.

Ubuntu :: Sudo: Unable To Resolve Host / Setting Up Network Sharing With Samba?

May 21, 2010

I am having a problem with Ubuntu 10.04. I was setting up network sharing with Samba. Set up went fine, then I decided to change the hostname.

Following instructions I found on the web, I edited etc/samba/samba.conf to reflect my desired hostname.

Now I have to use superuser to run synaptic or update center. I don't know what else I have "broken".

I would like to change my hostname, if I did it incorrectly for 10.04 please enlighten me.

Ubuntu Servers :: OpenERP And Drupal Environment Don't Get Along

May 20, 2011

I had OpenERP completely installed and running just fine. All basic install instructions just worked out of the box on Ubuntu 11.04. Now, we also are going to develop our own web site. For that we needed a web development environment. Due to the small size of our home business, we have to do it all on one PC. So I went ahead and installed everything needed to get Drupal going, among which I had to install:


and other packages.It all works like a charm, but now my openerp-web crashes when I start it with the following message:


[20/May/2011:16:17:19] ENGINE Bus STARTING
[20/May/2011:16:17:19] ENGINE Started monitor thread '_TimeoutMonitor'.
[20/May/2011:16:17:19] ENGINE Started monitor thread 'Autoreloader'.


For those that do not know it: it is a module that interfaces with the OpenERP server software to allow people to access the system through their web browser, effectively eliminating the use to install a client on their PC. Very practical for our light weight laptop that we use in combination with my PC.

Normally one would connect by browsing to [URL] and automatically get connected with the OpenERP environment.Now, however, that does not work anymore with the above error as a result. Do you guys have any idea if I have to configure something in Apache to get this working again? Possibly with instructions, otherwise I'd get lost again in no time.

Ubuntu Servers :: Samba In Large Scale Environment.

Is there a way to add a wildcard like $(USER) (that's logged in)//fileserver/ students/classof2011/Bill_Gates? Or would a directory path have to be created for each student?Either way is fine. I'm just curious what the proper protocol is for completing that task.

Ubuntu Servers :: PSSH - How To Use Sudo

Oct 24, 2010

I have a set of servers that I have to manage and I thought that pssh (parallel-ssh) would be a great tool for the job. Except that I can not see how to use that with 'sudo'. I can set password-less ssh between multiple servers for a given user. But I cannot see how to do administrative work if I cannot call SUDO as it requires a password to be entered firstly.

Ubuntu Servers :: 10.10 - Can't Sudo Apt-get Update

Mar 16, 2011

I wanted to installed transmission on my buntu server box 10.10 tonite so from my laptop top i ssh'd into it...which took an unordinary amount of time.. went to type in sudo apt-get install transmission half way through each word at the terminal prompt it would just hang...had to wait then it would recognize my typing and i could continue....pressed enter waited a long time; then noticed i coulnd't connect to the repos?

Ubuntu Servers :: Can't Sudo When X Forwarding

Jul 13, 2011

I'm trying to set up my mythtv backend on a headless box. The many tutorials out there tell you to run mythtv-setup from a machine with a display by x forwarding through ssh.


ssh -X username@ipaddress /usr/bin/mythtv-setup

The x forwarding works fine except that the first part of the mythtv-setup requires you to stop the mythtv-backend process which you have to do as root. It brings up a box asking for your password (much like is would if you just typed sudo xxxxxxx in the terminal) but it won't accept the password. Looking in the auth log it seems that it can't authenticate


Jul 13 11:21:08 server su[21869]: pam_unix(su:auth): authentication failure; logname= uid=1000 euid=0 tty=/dev/pts/1 ruser=administrator rhost= user=root
Jul 13 11:21:10 server su[21869]: pam_authenticate: Authentication failure


Now I know that my account (administrator) can have root privileges because I can sudo xxxx to my hearts content via ssh in the terminal, but it seems to not work when it's being requested from a forwarded X window....

Ubuntu Servers :: WAN IP Address Wont Resolve?

Feb 18, 2010

Ubuntu Server 9.10, with apache, proftpd, mysql and the goodies.

I have wordpress installed and setup under /var/www/

The LAN IP address resolves perfectly to the index.php

However I can not get my WAN IP to resolve. My ISP blocks port 80, so I have my router setup to forward port 81 externally to port 80 of my server. I know the port forwarding is setup correctly and working, because I can go to websites like url and test that port 81 is indeed open.

I also have DynDNS setup on my router and through an account with them, to update my IP address with any changes, to a host name. But because port 80 is blocked I have to access it with, host.name.org:81. Ive had this system up and running before with no issues. Now I can not get the host.name.org:81 to resolve.

Neither can I get my ip address xx.xxx.xx.xxx:81 to resolve.

Ubuntu Servers :: Can't Resolve Hostname From Windows

Mar 3, 2010

I have two computers.

Computer A = windows 7.
Computer B = Ubuntu Server 9.10

Computer B automatically receives an IP address from my router.

I can ping computer B from computer A using the IP address. I cannot ping computer B from computer A using its hostname.

My router did not show a hostname under it's active clients table. After some searching I found a threat where somebody suggested modifying /etc/dhcp3/dhclient.conf and adding 'send hostname "blahblah"' This allowed me to see the hostname in my router but I still cannot resolve it from my windows box.

Ubuntu Servers :: Create Secure Shell Environment For Users?

I was planning on using my VPS to grant some of my friends shells. The problem though is that I don't want them doing crazy stuff on it, like using up all my RAM or disk space. I would like to limit them to a very small 25 mb disk space, and allow them only certain application in /usr/bin like python perl irssi screen etc. I do NOT want them to be able to cd out of their home directory. I really want this to be setup like the shell provider SHellium. I can setup the FTP and SSH stuff myself.
