Ubuntu Servers :: Prompt Root Password When Attempt To Manage Users And Groups Through The GUI
Mar 20, 2010
So i have a fresh install of the server edition of Karmic, i'm running the Xfce desktop. When I attempt to manage users and groups through the GUI, I am prompted for what I think is the root password, the reason I say this is because the account I am currently logged in has sudo privileges and it does not accept that password at all, but I read that by default the root account is 'locked,' (to be honest it was so long ago since I last installed Ubuntu I completely forgot if it is or isn't, my current desktop installation has su access) is it asking for the root password? why doesn't my current user account password work if the root account is 'locked'? I can perform all other administrative tasks with sudo no problem.
the funny thing is, I have the exact same setup in a virtual machine, the same problem happens, except for some strange reason after changing the password on the only account (besides root), the password required to administer users and groups stayed the same after the change. (at the time of installation I just put both the user and root password the same and now that it is setup), i'm now ready to change the passwords. except now I read that the root account is locked by default, but this strange problem occurs.

I'm running 10.10 64-bit and have configured it for root graphical login for administration of the system. When I log in as root, I can run all menu items in System -> Administration with the exception of Users and Groups. When I try running this, the application starts, but I only get an animated spinning disk that doesn't stop, can't modify the users properties and I can't close the application unless I go to System -> Administration -> System Monitor -> Processes tab , highlight users-admin and click End Process.

I recently was able to network 2 computers at home and I wanted to make my password more secure. When I try to edit my password via System>Administration>Users and Groups, it doesn't workI am able to edit my user settings. When I change my password I enter my old one and it accepts my new one. Problem is when I try to install programs, login and do other things it only accepts my old password. How can I change my password?

I'm currently running a small server using 9.10 and I wondered if using groups was a possible route in order to keep users away from the bulk of the file system and keep them in locked their home directories.
What I planned to do is use a group named 'allowsystemfiles' to be added to admin accounts, then to set parts of the file system to that group, along with the permissions 0760 to keep non-admin users out.
Is is a good idea or will this hose my system?

I successfully configured a VPN using IPSec(Openswan) and xl2ptd. While roughly following this guide (among countless others): [URL]
The VPN-Connection works fine, connecting to it is also a swirl, I can reach all that I want in the network, and also the gateway to the Internet works - everything being routed through that VPN.
Now my problem is actually the next steps, and I didn't succeed finding the right result on any possible search:
a) I want to limit, that the VPN-Connection is only used for distinct connections to hosts, that aren't in a "company subnet", but the IP's are publicly available. (Example: The Target-IP 8.8.8.8 allows per iptables, that only my VPN-Host 1.2.3.4 accesses it via SSH, and thus I only can access that Target-IP via SSH when I'm on the VPN). When actually browsing to the ubuntu-website, I want, that NOT the VPN-Connection is used but rather my normal connection (as a reference: i'm on a Windows-Client - not my choice, btw.)
b) I want to have several such "limitations" grouped, and give users 'access-rights' to certain hosts (Examples: Admin gets access to all on all ports Testers get access to some machines on distinct ports CEO gets access only to the mailserver via POP3 or IMAP

I have Apache up and running and have a few virtual sites enabled. All these sites belong to the same user and group and the directory root for each site is in /home/{same-user}/www/{site-name}/htdocs/
I use Samba to connect from Windows to these directories and by default, files and directories are saved as the {same-user} and {same-group}. My question is, would it cause a problem if I changed the user and group in the virtual server directives in /etc/apache2/sites-available/site.conf files, giving apache permission to write to these files and directories. In the past I have changed the user and group to www-data (the default) but this seems inefficient an cumbersome compared to what I intend to do.
I use the server mostly for development, although at times I have a small site or two available to the public. Before I do this I want to be sure I'm not leaving a gaping security hole by changing these things. If this is all wrong, what is the standard way of running virtual hosts from apache and what is the standard document root for virtual sites?

I have Ubuntu 10.04.2 (Linux 2.6.32-33-server on x86_64) with OpenLDAP 2.4.21 and Webmin1.550. I converted my ldap database from another system with the older style schema (OpenLDAP 2.3.3 with slightly older Webmin version 1.480) and no longer use slapd.conf, but the newer slapd.d format.
It all works fine except for one thing. When I add a new user, it lets me type in the additional LDAP fields:
But when I click the Create button, all the fields get jumbled together in the Title/Position box with a diamond question mark delimiting the fields:
Modifying existing users (which have the Additional fields displaying correctly) also has the same result - it moves the fields all into the one Title/Position box with the diamond shapes with question marks inside between each entry. Is it a problem with my schema files? I tried reverting to the older shema files and slapd.conf and it still did the same thing on the new system. I am really at a loss.
Here is also the output of ldapsearch for that user (host and samba ids are sanitized):
Previously added users that show the fields properly have "description:" and then the field listed for each Additional LDAP field. Also shouldn't the "title" be visible in plain human readable text here? - it looks like it encrypted it somehow - similar to a password hash. The older system works fine and the fields are all readable and in their proper locations. But the new system just doesn't work right.

The question is, as far as I know Ubuntu distro adds a user created with useradd to supplementary groups automatically. For instance, I want to enable sudo for all newly created users on my LiveCD and want them to be added to the group 'wheel' on creation. I'm sure it is possible to do it in Fedora, but how?

I followed instructions to enter single user mode by adding single at the end of kernel line but after that it doesn't ask for root password but brings up the sh# prompt. Isn't that supposed to be insecure? I understand for this the grub password can be applied but even after adding "single" it should ask for root password..or it should not..??

I already know of a work around to fix this problem, but I guess my question is why is this not working as expected? I am using a Windows Server 2008 R2 Active Directory for authentication.
I have run auth-client-config for the ldap profile and pam-auth-update. When running getent passwd, I get a list of both the local users and the users in the active directory (with populated information in the Unix schema extension). When running getent group I get a list of both the local groups and the groups in the active directory (with populated information in the Unix schema extension).
Interestingly enough, though, when I run su DOMAINUSER, after the prompt for the password I get an authentication error. In /var/log/auth.log I can see an entry with pam_ldap: missing "host" in file "/etc/ldap.conf". The SRV records in the DNS servers resolve correctly. I've checked this with nslookup and I have seen the records within my zone file. Obviously if the ldap.conf file is working with getent and the ldap server is resolving from the SRV records, it is working fine.
The interesting part is that the Windows Server 2008 R2 AD machine shows in the event viewer that there was a successful authentication, yet the Ubuntu box says no. When I add the host within the ldap.conf file, everything works...getent and the actual authentication, either initial login or su.

I am currently trying to set up a Samba domain server. In the Samba-HOWTO-Collection I found an
example file.(Point 3.3.3.1) In the explanations of the example below, the author says I need to map UNIX Groups to NT Groups. He writes a shell-script of how one could do it, but when I copy it and then execute it, I get the error:
Bad option: rid=512
Bad option: rid=513
Bad option: rid=514
The other groups do get mapped, just the Domain Admins, Domain Users and Domain Guests dont. This is the shell from the HOWTO:
#!/bin/bash
#### Shell-Skript f ̈r sp ̈tere Verwendung aufbewahren
net groupmap modify ntgroup="Domain Admins" unixgroup=ntadmins rid=512
net groupmap modify ntgroup="Domain Users" unixgroup=users rid=513
net groupmap modify ntgroup="Domain Guests" unixgroup=nobody rid=514

On startup - prompt asking for apache certificate password doesn't accept input. Can switch to another tty but can't restart apache due to the port already being bound (suppose I could change ports for apache config after startup but that's pretty ugly and clearly not the right way to address the problem.

I recently installed vsftpd on my server. I noticed that users on the machine can login into vsftpd with their username and password on the machine and go to their root dir "/home/username".Now, I want to give some people a vsftpd username and password so they can upload and download files and folders to their folder, but this folder has to be in the "/var/www/(username)" folder. I don't want them to be able to go to any other folder than their own folder like "/var", "/etc" or "/home" etc. Also I don't want them to be able to login on the machine as a user, through putty for example. They should only be allowed to acces their folder with vsftpd, nothing else.

Ive always had luck doing any kind of updates to my system. I let it auto install the security updates lastnight. Today when I rebooted the machine it just hangs. I would like to attempt to boot only to a command prompt so that I can atleast use vi to edit files and fix the system. Do I have to edit grub to do this or is there keys I can press during boot up?

I have forgotten my root password for MySQL, what can I do to recover it, I've found a few guides but they don't work on the newer versions of Ubuntu.I am running on Ubuntu 10.04 server so MySQL is an upstart job so the methods I've seen with launching it without the access checks haven't worked for me

I have forgotton my root password for mysql. I followed some instructions on a website and now I am not sure what i have done?Basically, when I now try and start mysql I get a notification that i have converted the init script to an upstart. I dont know what this means.
Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start( utility, e.g. start mysql mysql start/running, process 20301.

Using 11.04, and just installed mysql 5.1.54 using synaptic
I was following the instructions here and the installation when fine,
except that I never got a screen to set the root password.
When I try to set the password using these instructions, following either
"If you have never set a root password for MySQL" $ mysqladmin -u root password NEWPASSWORD
OR, since the first method failed me, then: "However, if you want to change (or update) a root password, then you need to use following command" $ mysqladmin -u root -p'oldpassword' password newpass
Either way, it fails. Question:
1) why am I not being prompted to set a root password during installation?
2) what can I do now to fix this??
I am trying to learn Mysql, so don't presume I know anything about command syntax (cookbook instructions) For example, the first command above,I tried with with NEWPASSWORD in quotes, and then without. Likewise for the second command.

Imported users and groups (UIDs 500 and above) from Redhad to Ubuntu 9.10 by appending users to the passwd, shadow and group files. Users and groups appear to work, but they do not show in the Users/Groups GUI. Is that because they do not start at a UID 1000 and up? What are my options to make them visable?

I upgraded from 8.04LTS to 10.04LTS desktop. I can do sudo as root at the terminal, but I can't pass authentication trying to add a user (System->Administration->Users and Groups).
Here is what I got: An error occurred while checking for authorizations: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. You may report this as a bug.
