My first post. I've been using Ubuntu Server edition (Hardy) happily for some time now.
I use sudo regularly during configuration of new services. It always works/authorises within seconds, however, it recently became very slow, to the point of being nearly unusable.
In /var/log/auth.log I noticed a regular working pattern like this code...
A rather new user here, was messing with the preferences on a user folder of mine on Karmic, looking for a way to make the folder invisible to users (like the old windows option). Set it to 'none', then closed it, returned to the directory finding the folder with a box with an 'x' on it.
Went to open it, it says 'access denied'. So I think 'okay, how do I undo that', go back to see if I can restore it back to 'read & write' with no sucess.
Seached the forums for a solution to this issue, most of solutions revolve around 'gksudo nautilus' which I attempted to open via command-line. Nothing seemed pop open after I entered my password in responce to entering said command-line, probably because I really don't know how to use Nautilus.
I posted this yesterday, but my post completely disappeared (I looked high and low -- nothing.)
I am using Ubuntu Server 10.04, all the latests updates.
For an FTP Server, I use ProFTP.
One specific directory, and it's subdirectories on my server will not download at a reasonable rate. They move at about 17-50KBPS.
All other folders work fine, at around 1.5-2.5MBPS.
What is going on? I have no idea how to troubleshoot this. The files being transfered are in a directory under home. They should have no permissions issues (I reapplied the permissions I want already), I tried restarting ProFTP, the files vary in sizes (from a few kilobytes to about 120 megabytes).
I use Webmin for most web management.
I am not having overload issues with my network card or CPU utilization while downloading these files. They are being accessed from the local network.
This issue is taxing because the files in question are backup files.
Accidentally I changed the ownership of all the directories under / to my own instead of root:root. Now I am unable to use sudo and many bad things are happening. Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?

I want to do the exact opposite, I want to make Ubuntu's sudo command act more like the sudo command from another distribution. ie I want there to be one root password
View 8 Replies View RelatedI've been having a problem with administrative apps all the way from last years' distros, and in 10.04-x64 it's still here.
When i launch an application that needs gksu, it simply hangs waiting for a gksu window that never shows up.
If i launch another administrative app, it hangs as well.
When i look at the process list, i get a lot of gksu instances, all sleeping.
if i kill those processes, the mentioned apps resume with an authentication error
But if i use a terminal and type sudo <app>, it hangs for a few seconds, then prompts for password and it works fine.
I don't know why it works so badly, but it needs to be fixed soon, many new users will surely find this very frustrating.
I run ubuntu 10.04-64bit on a AMD-Athlon-x2
So installing a programm is a problem. I like to install Aqualung. "/.configure" works. But "make" seems to be not installed. "checkinstall" seems to be not installed "sudo apt-get make" does not work. I have no internet connection with linux, because I have no idea how I install the network card. I guess this sudo command use internet? Is there another way to compile that program? (And just by the way, why must this be so difficult?
View 3 Replies View Relatedfter using Ubuntu and finding it way too unstable, Opensuse and finding it bloated, Arch and finding it confusing, I have finally settled on Fedora 11.The problem that I am having is a minor annoyance. I found that my default user couldn't use Sudo, so I added the following to the sudoers file:Quote:USER_NAME ALL=(ALL) ALL -- Where User_Name is the the name of my default user.The problem is that I can now use sudo but it is incredibly slow. For example if I type sudo yum install _____It'll ask me for my password and then pause for a minute or two literally before proceeding. It isn't the network causing this problem because it does the same thing if I issue commands that are specific to files only on my computer. Interestingly enough I don't have this problem if I use tty, only in Konsole.

View 2 Replies View RelatedI've enabled root under Ubuntu (i know frowned upon), I'd like to change the default behaviour of sudo so that rather than requesting my password (the password I logon with), it requires the root password.
Have searched the forums but can't find the answer.
I changed my hostname by running sudo gedit /etc/hostname and changing the word there. Then I discovered that hadn't done anything so I used sudo hostname newname. My hostname was changed then but I tried to run sudo gedit /some/thing/else.txt and it said:
Code:
sudo: unable to resolve host newname
No protocol specified
(gedit:5512): Gtk-WARNING **: cannot open display: :0.0 and it says the same with sudo or gksudo for any program that has a gui including synaptic. I can run vi but I have no idea how to use it. I think the problem lies in the lines in /etc/hosts which still say

with the problem being that it still says localhost and my local IP address are ubuntu instead of newname. So if you could tell me how to edit that with vi or some other command line program
How I can make sudo Ubuntu 10.04 session an hour and not few minutes?
Now I have to write my password for sudo commands every few minutes.
On my HTPC/Server unbuntu box I have installed logwatch in order to get a daily look on my computer activity.
And I often have this line in the report :
Quote:

/usr/bin/gconftool - 3 Times.
The corresponding line in auth.log are :
Quote:

./auth.log:Jan 28 07:59:32 sweetBox sudo: root : TTY=unknown ; PWD=/ ;

When I run sudo as a normal unprivileged user, it asks for my password, not the root password. That's often convenient, but it reduces the amount of information someone would have to have in order to run commands as root. So how can I make sudo ask for the root password instead of the invoking user's password? I know it'd be done with a line in /etc/sudoers, but I can never seem to properly parse the BNF grammar in the man page to figure out exactly what to write.

View 5 Replies View RelatedWhat are the differences if I build (./configure, make, make install) an app when log in as root vs a "regular" user other than I have to use sudo for make install? If an app is built from a non-root account, will it be available to every other user on the system?
View 4 Replies View RelatedI've setup the .ssh/authorized_keys and am able to login with the new "user" using the pub/private key ... I have also added "user" to the sudoers list ... the problem I have now is when I try to execute a sudo command, something simple like:
$ sudo cd /root
it will prompt me for my password, which I enter, but it doesn't work (I am using the private key password I set)Also, ive disabled the users password using
$ passwd -l user
I am trying to harden my system ... the ultimate goal is to use pub/private keys to do logins versus simple password authentication. I've figured out how to set all that up via the authorized_keys file.Additionally I will ultimately prevent server logins through the root account. But before I do that I need sudo to work for a second user (the user which I will be login into the system with all the time).
For this second user I want to prevent regular password logins and force only pub/private key logins, if I don't lock the user via" passwd -l user ... then if i dont use a key, i can still get into the server with a regular password.But more importantly I need to get sudo to work with a pub/private key setup with a user whos had his/her password disabled.
1) I've adjusted /etc/ssh/sshd_config and set PasswordAuthentication no This will prevent ssh password logins (be sure to have a working public/private key setup prior to doing this
2) I've adjusted the sudoers list visudo and added
root ALL=(ALL) ALL
dimas ALL=(ALL) NOPASSWD: ALL
3) root is the only user account that will have a password, I am testing with two user accounts "dimas" and "sherry" which do not have a password set (passwords are blank, passwd -d user)
The above essentially prevents everyone from logging into the system with passwords (a public/private key must be setup). Additionally users in the sudoers list have admin abilities. They can also su to different accounts. So basically "dimas" can sudo su sherry, however "dimas can NOT do su sherry. Similarly any user NOT in the sudoers list can NOT do su user or sudo su user.
I'm using Debian and openSUSE 11.2 and the sudo-ing is a bit different in Debian. It actually makes more sense to enter your own password like in Debian to achieve sudo status than have to use the root password for sudo status. If I for example would like to give someone on my system sudo rights, I can't give them the root password. Thats just like giving them root access. Or is there a way to change that behavior, or just change sudo password, in openSUSE? Or maybe any other best practice for giving users sudo rights?

View 2 Replies View RelatedI 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.

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.
Code:
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
Code:
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
[code].....
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....

View 1 Replies View RelatedMy disk is very slow after I installed ubuntu 10.04 over my old 9.04. Doing some tinkering helped a little code...
But it is still far too slow. On the other version, I had a custom partition setup, with the home partition with 100GB, and ext3 (and other partitions for swap, boot, root folder and space for a windows partition I never cared to install ).
This time I am using a standard Lynx setup (2 partitions, the swap and the main one with almost 250Gb, using ext4).
Some applications I develop, that use disk for some unit tests, are now very slow to work with. Is there a way to making it faster? Going back to 9.04? Waiting for 10,10? Gparting and making partitions smaller on ext3? I don't know if any of these will work.
I worry about mounting properly an external USB hard disk.
It is a sata 1To NTFS formatted
It works perfectly with a XP SP3.
With xuxbuntu 10.10 , with ntfs-3g installed , it is VERY long to transfer data:it took almost 3 days for 360Go.
When I connect to the station , it automatically mount by itself on /media/disk without any option;I suspect bad options are used and no use of NTFS-3G.
How to oblige it to mount with good options?
