Debian :: Administrative Tasks Fail To Start
Sep 4, 2010
Over the past few days, I've noticed that administrative tasks sometimes fail to start. I'm asked to enter the administrative password, "Granting rights" appears in the bottom panel for a few seconds, but then disappears. I'm using Debian Lenny. This is only an intermittent problem, and if a task does fail to start, it will start on the next attempt. Tasks which have failed to start are:
*Launching Synaptic form the System menu.
*Launching a root terminal from the Applications menu.
*Launching Nautilus with root privileges from a terminal using gksu.
After coming across the following post, I thought maybe it was an issue with kernel 2.6.32-bpo.5-686, because I'd recently upgraded to that kernel too, but I'm advised that that isn't so.It was suggested that something else from backports might be causing the problem.

I am a student at DeVry University, newly introduced to Fedora and Linux in general, and have a project whereby, we have been asked to consider some administrative tasks that we could automate via a script.I was wondering if there were any thoughts or directives from the community on what admin tasks you guys find to be of inestimable use in automating via a Linux script.
I am new to the Linux commands but have done a wee bit of programming before in C++ and others.I have also done basic DOS batch files before.

I find myself using SSH from my mobile phone to manage administrative tasks when I'm away--completing updates and the like, things that can be done during normal usage but sap my RAM and CPU to the point of frustration, given the hardware I've got to work with. It's convenient, I can do what I wish (without the benefit of an X session) while I'm at work. The issue I run into is the fact that my auth.log is littered with items like this:
Code:
May 16 12:53:17 BETA sshd[18941]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=200.111.184.180
May 16 12:53:19 BETA sshd[18941]: Failed password for invalid user lala from 200.111.184.180 port 41787 ssh2
May 16 12:53:25 BETA sshd[18943]: Invalid user master from 200.111.184.180
Which tells me that some inconspicuous person and/or botnet keeps trying to get into my system. This is generally annoying; at this point, my system isn't used for anything particularly critical; however, the fact that only failures or questionable successes--such as those from my mobile, the IP and Host of which can vary a fair bit (and the host resolution almost always fails, based on the way the IP/Host advertisement is presented to an external host is established--it's essentially manufactured)--doesn't tell me who/what has figured it out. I've done what I can to tamp down SSH access to the system, root is blocked via SSH (a moot item, since root isn't allowed locally), I've limited only my own username as allowed to connect via SSH...all it would take, though, is an alphanumeric dictionary that hits the right combination to get a password prompt, and to be able to brute-force it from there.
Overall, I know there's few, if any ways, to prevent someone attempting to get into my system via SSH; what additional steps can I take to minimize the possibility that I might end up compromised?

The title says it all. Is there a way to just click ok to administrative tasks instead of having to enter my password every time? Sort of like Windows 7's UAC.I'm using ubuntu 10.04 LTS. I don't want to log in as root

I found a similar problem. The poster used a similar title "Administrative tools fail to open - karmic" I also have karmic and four tools fail to load; Ubuntu Software Center, Hardware Drivers, System Testing, and Update Manger. Synaptic and System Monitor run. I ran update-manager and software-manger and was told module pygtk does not exist. I ran "sudo apt-get install pygtk" and it said that did not exist as a package. The terminal update and upgrade also work.
Code:
me@me-laptop:~$ update-manager
Traceback (most recent call last):
File "/usr/bin/update-manager", line 26, in <module>
import pygtk
ImportError: No module named pygtk
me@me-laptop:~$ software-center
[Code]...
Would the best solution be to reinstall the OS from fresh downloads as at least the Hardware Drivers tool works with the live USB?

I often get responses from people who first say: "Are you sure? You want your network to be exposed to the outside world?" I am not experimenting on a Production Server of NASA or any Security Concern Department. Friends, there is no harm in experimenting on your personal computer or on a test computer which is isolated from the production environment. Look at hackers! What do they do? If they don't know how security is breached then how would they come up with security measures?
If my question reads... "How to let any user perform Administrative Tasks on a Linux System irrespective of his/her privileges on that particular system?" then I would not get the right answers in the first place. They will say... "You are letting everyone destroy your system... are you sure you want to do that?" My question is: Why should we restrict ourselves from experimenting even if it sounds weird to other people?
I give you an example where it is desirable to let an unprivileged user perform certain tasks. You want to know if there are any employees in your office who are storing videos in their home directory and filling up the disk space to a great amount. You have a department called "Command Center or Data Center Operations or Help Desk" call it whatever you would, whose work is to monitor such activities, and you create an account "monitor" for them to monitor such activities but they are not able to do them:

I have a feeling this may be a bit of a stupid question as it seems like one that must have a very basic answer so for that I apologise but I have yet to come across or work out the solution. The problem I have is that I cannot do anything that requires administrator priviledges from within GNOME without doing it directly from a Terminal using the su command. The reason being is that GNOME will not allow me to log in as 'root' from the normal login screen. So therefore I cannot do something as simple as edit a text file that is not in /home/'my username' as I do not have the required permissions.

I am currently running a VPS with Ubuntu Server 10.10. I have been trying for a few days now to get some programs to run when the system starts, but with no luck. I am trying to use rc.local to do this, there is an:
/etc/init.d/rc.local - http://paste.monsterprojects.org/mpbjhwhbjzhbjrr (Was already on the system, I have not edited this)
and:
/etc/rc.local - http://paste.monsterprojects.org/mpbjhwhbkkkhwez
If i run the /etc/rc.local script manually all the programs start fine, and if i run /etc/init.d/rc.local start, all the programs start fine. But for some reason they just don't seem to be starting when the system boots.

I don't know if this is the right place to post this but here goes anyway.
System:
ASUS Pro50n Laptop
Distro: Arch Linux
WM/DE: Gnome
I've recently installed Arch linux with the gnome desktop environment, and everything is working fine apart from HAL and DBUS. I'm not sure why this problem is happening and I have no idea about any settings for HAL and DBUS all I know is what it says in the wiki.
The problem I have is that HAL and DBUS fail to start. I have tried /etc/rc.d/hal start and get the message BUSY.. then FAIL. I have tried /etc/rc.d/dbus start and get exactly the same. I have tried restart and that also fails. *EDIT* I have just tried /etc/rc.d/dbus start again without changing a thing and dbus has started successfully but HAL still fails.
The further problem, which I think is related to HAL not starting... possibly... Is that I can't watch DVD's / anything in the DVD drive. I can see it in Places >Computer as "CD/DVD Drive: 3_MEN_IN_ANOTHER_BOAT" but when I click to load it or if I open Totem and try and load it all I get is the error: Unable to mount location: Not Authorized. Is this related to HAL or is this a completely different issue?
*EDIT* fixed the HAL problem, reinstalled xf86-input-evdev package and it seemed to fix the problem. However I am still having a problem with watching DVD's

I have installed freeradius from repositories in both Debian and Ubuntu. I have built from source with 'fakeroot dpkg-buildpackage -b -uc' on both the official freeradius source code and the source provided by apt-src in both Debian and Ubuntu. On a normal install via aptitude there is no ssl-support, I understand this is because of license issues. Otherwise is works, but is of course useless in a wifi-auth setup. On a install from source code, after editing debian/rules and debian/control as recommended different places on the net, freeradius fail to start because of ssl error. Same on install via source code downloaded directly from [URL]... Anyone have a working ssl-enabled freeradius server running Debian or the likes?

As I have developed a part of my project based on crontab and now one of my team member has raised a question based on performance and load/stress, I would like to know the following limits of crontab.I assume each line in crontab file is a task; and also crontab would hold completed and pending tasks.1. How many tasks (both completed and pending) could crontab hold/handle?2. Will crontab run as expected if there are 100s of completed and less than 100 pending task?

Im running a Debian 2.6.26-2-amd64 webserver with apache2 only on a Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz that has 2GB of ram in it. I installed htop a few days ago and have been looking on it for a few days now. the server idles on about 80~ish tasks constantly with arond 20 apache tasks/connections to it all the time and the cpu usages of the 2 cores at about 1% each. but asoon as more apache2 connections/task get started and the servers tasks reach 120-140~ Apache2 timesout if you try to go to the webpage i host on the server. when it's back down to around 80~tasks you can reach the webpage once again. why is this ? what's causing this to happen ?

I have installed fedora 13 , 86_64. and was working fine until now. The problem was that JEXEC service Froze while booting. So I removed it /etc/init.d. The next time when I booted ATD service Froze, so I removed it by the same way. Next it was the turn of CROND followed by KSM , KSMTUNED. Then came ABRT-DAEMON which I had to type a #yum erase abrt* command. Finally it came to the turn of SM-CLIENT. I don't know where it is or what it is. Didn't find quality posts on the internet. What the heck should I do and I dont want to do a reinstall.

I am having a RAID5 with a spare(total 4 disk).then the steps which lead me to a problem:
1. i was doing I/O on the array.
2. i pulled out a drive manually. So the spare drive took care of the failed one and started rebuilding. then
3. in the, mean time i pulled out the power plug of my NAS box.
4. After power up i saw my array was not active(by -D command option of mdadm). then
5. i executed: mdadm --assemble --scan /dev/md0 it gave me
I checked into the linux source and found that bd_claim is a function inside fs/block_dev.c and it failing due to which lock_rdev function (calling bd_claim in md.c) is failing and we are not able to start the array.I don't know why my RAID is not live after power on.
Plese help atleast can i save my data?

After upgrading Centos 5.4 cluster nodes to 5.5 all virtual services failed to start. All virtual services are marked as 'failed'. The reason: new /usr/share/cluster/vm.sh requires 'which', but this is not reflected in rgmanager-2.0.52-6.el5.centos.
Solution: run 'yum -y install which' on all nodes, and reboot cluster. Hope that will save somebody hours of downtime.

I am new to this O/S. I have tried Mint and Ubuntu. There are some problems I would like to work out by myself before I take short-cuts, as if.I have tried to install codecs for my o/s media player and get a reply from computer "xxxx does not have sudoer rights, you will be reported."I tried to get sudoer rights and was told I had to have administrator rights first. To get administrator rights I needed sudoer rights. I decided to come to forums to ask and this is my first post.
Is there a danger in getting administrative rights? If so, I would still rather like to face the danger than not be able to play music. And how do I get real superuser rights? My root account is localhost.localdomain and my login account is XXXX. I would have access to everything rather than have a warning that the administration is receiving reports of my activity. Might anyone have help?
