Ubuntu :: Cant Access Tty Job Control Turned Off?
Jul 22, 2010
I am getting the following error after booting my Ubuntu machine. Worked fine recently and after I upgraded some stuff when I rebooted the machine I got a green screen then hit an arrow key and got the following error message:Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
[code]....

I recently bought the book Hacking: The Art of Exploitation, and it came with a live cd of Ubuntu. I run it on my Mac, but I get this in the console screen whenever I try to load it:

due to low disk space there arose a problem. Now I re-installed Debian along with winXP as dual boot. XP works as it was before. but i can't open Linux. When i select Debian on boot-select page, Debian starts but stuck at a point as shown below:
check root= boot arg cat/proc/cmd line
or missing modules,devices:cat/proc/modules ls/dev
ALERT!/dev/sda3/doesnot exist. Dropping to shell;
Busy Box v1.1.3(Debian 1:1.1.3-4) built-in shell(ash)
Enter 'Help' for a list of built-in commands.
/bin/sh: Can�t access tty; job control turned off.
(intramfs)
i hv searched a lot but couldn't come up with a correct solution.i tried editing the grub by pressing 'e' when grub is displayed and added the line acpi=off irqpoll and then start booting. but the result was same.

"/bin/sh: can't access tty : job control turned off(initramfs)"This comes when I boot.Hi, I tried to netinstall Debian testing on my brother's computer and only selected the "Standard system". I think it installed Grub 2.The Grub boot menu is also not showing the Windows 7.Also, I have this new terminal as (initramfs) and do not know what to do. I am stuck with (initramfs) which I have no clue about.

Although I'm a linux user, I don't know much about the whole booting process myself. I normally have a friend that I can consult when things don't go the way I expected. But here's the thing: he updated my computer and went away. And of course I can't reach him and I really need it to work. And moreover, I want to be able to sole things myself.
The booting process stops halfway. The last thing it says is: can't access tty: job control turned off (initramfs) ...

This is the difference in the output of a port scan using Zenmap on the same system with UFW turned off and then with it turned on. It is obvious that UFW works.

The wireless connection works fine. The wireless switch automatically turns itself on every time I start the computer. However, after turning it off, I can't ever turn it on again unless I restart the computer. And because of this, the wireless connection is disabled until the next time I start the computer.I don't think this is a hardware problem because the switch can be turned on and off, although not in the way I expect.
I'm using ubuntu 9.10 on an Acer Aspire 4740G. The command [lspci | grep Network] shows Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01). the [rfkill list] command shows (when the switch is on)
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
and, as expected, shows (when the switch is turned off)
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
I just want to be able to turn the switch on or off at any time I want as long as the computer is still on.

We have a sipmle office network set up that we also use use to connect to the internet, however of late the number of users has increased thus slowing internet access. Bandwidth upgrade is not an option thus i have to do bandwidth shaping on our linux router. The question is how do set the squid configs to allow certain IP's range a certain percentage bandwidtheg 60% and furthe divide the rest. Alternatively how can allow certain IPs to have higher bandwidth access.

I have a personal laptop and a work laptop. personal is running ubuntu 10.4(which im planning upgrade to 10.10 soon) and Win-Xp on work laptop. I would like to run ubuntu on work machine, but i need to use vmware vsphere client regularly as half my work is related to it.
Is there an alternative available for vmware vsphere client? How can i have ubuntu on work laptop and have access to VMs via the control center? Is running Windows-XP on ubuntu via vitual box a resolution? If yes, I have 3GB of RAM on my work laptop, is that enough?

I'm using squid for proxy server in FC6. I'm also using squidGuard for web-site access restriction. I want to do some exception now for website access. For example, squid user1 with ip 192.168.7.10/32 shoud not access facebook.com while all other squid users with ip 192.168.7.11/32, 192.168.7.9/32 and so on... can access facebook.com since facebook.com is not listed in squidGuard .db files

I've managed to setup Ubuntu Server 9.10, and created folders/files toview/edit/execute with Windows and Mac.
Now here is my dilemma, this is for a home server, and I will have 4 users(1 for myself, one with "admin" rights, my fiance(mac user), media pc, and a "guest" account for the computer or 2 that are out in the public(they don't need access to my taxes ).
I'd like to have it so that on my laptop, I can access the whole server, but some files/folders would even need me to put in a password. I want to do this because my fiance gets delete happy and deletes things, so if she goes on my computer she won't delete important info. I'd like her to have access to music, photos, and videos, as well as her having her own folder that she can treat as her hard drive.
The question is, do I need to setup a domain for this, or can I get away with a workgroup?

I have won my fight and my father in law accepted to give gnu/linux a try as his server and to run on the computer of the new company he is starting. One feature he would like is to be able to access his work desktop (graphicaly) from home. On my side, I would like to be able to control his desktop from home if I need to show him things. I already can SSH in terminal to install and maintain stuff but, to move the mouse around and point him where to click or what to use would be invaluable.

I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage.
Services like proftpd have:
AllowGroup ftpgroup
sshd have
AllowGroups sshgroup
And samba have
valid users = @smbgroup
But I can't find the correct option in Dovecot (/etc/dovecot/dovecot.conf) Do anyone have the magic option or a workaround thats doesn't envolve maintaining seperate user databases and password?

I'm using Sun One LDAP server, (Soon to be moving to openldap). I have one Master server, no slaves, about 60 user accounts.
I'd like to add an attribute to each of the users DN's to restrict there ability to login to specific hostnames. I.e. I have hosts A, B and C. Dev staff can access A and B, but not C, and support staff need to access all of them.
I found a link at [url] which talked about using 'hostsallowedlogin' and 'hostsdeniedlogin' attributes but I'm presuming these are bespoke. If they are, how do you configure the ldap.conf to take note of these attributes when authorizing access?

I am using Debian Lenny on a cluster. If I log in as a regular user and try to adjust the volume on the top right panel (Using Gnome), I get the following message"The volume control did not find any elements and/or devices to control. This means either that you don't have the right GStreamer plugins installed, or that you don't have a sound card configured.You can remove the volume control from the panel by right-clicking the speaker icon on the panel and selecting "Remove From Panel" from the menu."or ifenter "gstreamer-properties" in the terminal and do a test I get the following message"Autodetect: Could not open resource for writing."
if I become the root user and enter "gstreamer-properties" in the terminal and do a test, the test works. Alsamixer works as root, but not as a user.My user error for alsamixer i"alsamixer: function snd_ctl_open failed for default: No such file or directory"I am not sure what setting I need to change to which all users can adjust the volume. Problem 2:When I put in a usb stick I get the following error as a user.Cannot mount volume

Quick explanation about what this thread is: by way of an article featured on linuxtoday, I learned about what appears to be an actively managed IP blacklist: [URL]
# This is a compiled list of dirty hosts associated with
# bruteforcing attempts, spam, botnets, RBN and the list
# continues to grow. The data is comprised of information
# compiled from Arbor Networks, Project Honeypot, FIRE
# (maliciousnetwork.org), Host Exploit, Shadowserver and
# a variety of other similarly based sites.
Quick explanation about what this thread is not: this is not intended to be a discussion about default deny vs. default allow (i.e. whitelists vs. blacklists), nor is this a call for enumerations of your own sshd hardening strategy. Please try to keep on point. That said, can anyone speak to the quality of the blacklist information noted above? And/or are there any suggestions for a readily available blacklist of "known better" quality? I plan to try including an actively maintained blacklist like this into a multi-layered approach for hardening an sshd bastion host.

I have configured squid proxy on centos 5.5 and some of my squid.conf file has following lines
Code:
http_access allow ncsa_users office
There are 3 users called "user034, user035 and user050" in the /etc/squid/squid_passwd file need to restricted access to internet except sites www.abc.com form anywhere in the lan. Once they logged in any ip, rule should apply.(that means no ip related acl, only user name related) How can I configure this in squid.

I have a shared folder that has it's access restricted to certain users on a file server at work. Currently when I try to add a user I follow this process:
Right click the Folder, go to Properties
Click the "Access Control List" tab
Select a user from the "Participants List"
Click Add
For most users this process works fine but with one of them I get the following error:
"Could not add ACL entry: Invalid Argument"
I also tried a script that a former employee created which seems to employ this command:
setfacl -m u:<USER>:rw- <PATH>
Running the command with the correct user and path returns a similar "Invalid Argument" error.
We're using OpenSuse 10.2.

I have ubuntu based web server running in home which I use for varying purposes. Now I have ran to situation that I would like ton set "access control" for my server so that on main page user can login and then he/she sees that what sites on server he can access.
Basically this would be simple to do with .htaccess protection, but it would be per directory solution and this is not so easy to manage. However what I wish to get done here is that there would be access control check and an login prompt on webserver document root which would require to authenticate if heading to non public section of webserver.
currently I got my server root like this
/var/www (server root, no website and here would come access control point)
/var/www/site1 (primary website on my server to where most of visitors are going to)
/var/www/site2 (secondary site for specific things on my server)
/var/www/directory1/site3 (site which I do wish to have for closed group only)
/var/www/directory2/site4 (my online education and studying portal which I wish to control)
And I would want to allow everyone to access site1 and site2 without any restriction
Now what kind of solution would work here ? I am not sure and I don't have full techical knowledge of making this reality, There probably is multiple ways to do this and one could be .htaccess control, however what I wish to have is an easy to manage system which is also expandable.

I don't know how this happened, but my keyboard copy and paste functions have stopped working. Oddly enough, I discovered that I can only copy and paste by using the third mouse button. Pressing down on the scroll wheel after highlighting text copies the text, pressing it again pastes it Ican still use the Edit-copy and Edit-paste menu functions.
I'm sure it has something to do with all the tinkering I have been doing with my desktop. I have been experimenting with CompizConfig and Cairo dock, changing my themes and things of this nature.

I cannot get any fan information from 'lm-sensors' or 'sensors', I tried to run 'pwmconfig' and got this:
Code:
Code:
But I have no tools to control the fan speed from 'acpi'. in particular '/proc/acpi/fan' is an empty directory.
There are no fan info/controls in BIOS either.
I believe the fans do not work as fast as they should and I am trying to find a way to fix this before the cpu cores are melted down from overheating.
