I'm trying to "repair" two Debian Lenny servers a friend of mine had installed and working fine, all of a sudden he calls and tells me the servers don't boot. He's getting this error messege on both, weird:
/bin/sh: can't access tty; job control turned off (initramfs)
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) ...
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.

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?
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.
View 6 Replies View RelatedThe 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)

and, as expected, shows (when the switch is turned off)

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.

After trying to do something with Windows 2000 which was installed on the machine, I decided to put Linux without keeping windows on the machine. First I try with Xubuntu (latest version) which was working but slowly, then I found that Debian could work fine on that machine. I have installed latest version 5.08 and was surprised how goodly old machine can work. I solved problems with screen resolution (change from 800x600 to 1024x768) but I couldn't find solution how to fix problem with sound.
Actually I don't have sound on the machine. I looked for a linux driver for that sound card and Dell is only providing windows drivers. Then I found that I can solve the problem with ALSA drivers but I couldn't find the easy way (or any way at all) to install drivers and to get back the sound. When I click on 'Volume Control' (top right corner of the screen) I get the message: '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.'

I'm just completing an upgrade from wheezy to jessie and get the following error
Code: Select allProcessing triggers for initramfs-tools (0.120) ...

E: intel-microcode: unsupported kernel version!
With a message like this I'm wondering if it's safe to reboot as well as how to resolve.
Is this somehow related to the change to only update the microcode on boot as reported earlier in the upgrade?
Code: Select allintel-microcode: microcode will be updated at next boot
When I run update-initramfs -u I get this error?

I am not sure if this is the correct section but it has to do with a faulty HD. So, the datacenter confirmed that the HD needs to be changed. They put it back and asked me when they should replace it. I told them to wait a bit.

My touchpad stopped working, most likely I have accidentally turned it off by some Fn-key combination (Fn-F4 on my laptop). Since then I was unable to turn it back again. What I've tried:
0. Same keycombo does not work. Actually, when checking with xev, Fn-F4 does not even toogle any KeymapNotify event. Some other Fn-combos result in KeymapNotify (e.g. screen brightness), some others (e.g. keyboard backlight) do not give event, but still do what they should do, and finally some do not do anything
1. Total power-off, also removing battery. This has usually solved touchpad problems on my other Fujitsu laptop, but not on this.
2. Checked xinput: it says, that touchpad is enabled
3. Also tried this trick: adding "options psmouse proto=imps" to appropriate config file. [URL] ....
4. Further playaround with psmouse, as described here:[URL] ....

View 3 Replies View RelatedFairly new to debian and linux and general. I have an install of debian wheezy (to run LinuxCNC). I went in the graphical interface to the 'monitor' section and changed the screen resolution. I had two monitors, one labeled monitor and another (I think) Lenovo Monitor.
There was a check box in the screen monitor window that said something like, "Don't use this display." I figured it might turn off the lenovo and default to the generic monitor listed. I clicked it and my monitor turned OFF!! I tried another monitor (Dell in this case) and same thing, no video output.
I asked on the LinuxCNC forum and googled, but I just dont' seem to be able to figure out what or how to get to the solution.
I have been able to Ctrl-Alt-F1 to open a terminal. But, I can't find any the right files and found that the xrandr command 'should' work, but doesn't.
Whenever I issued the xrandr command (other than man xrandr), I get "Can't Open Display"
I did find two outputs VGA1 and LVDS1 in this file /var/log/Xorg.0.log and this coincides with what I saw in the monitor window. These are the 'output' types and if the xrandr command worked I'd issue something like : xrandr --ouptut LVDS1 --auto
I read about xorg.conf, but I could not find any xorg.conf files in the etc/X11 folder. In some of the info I found, the xorg.conf was replaced in this or a recent version of Debian by something else and confuses me.
One person had a similar issue and he got to this directory: $HOME/.e/e/config/standard" and found files such as:
"e_randr.cfg" plus "e_randr.1.cfg" thru "e_randr.9.cfg"
But, I can't get to that folder. How to turn on my monitor display?
Debian, Squeeze, Gnome. Laptop AJP7521P. I had it on for a few daysThen i decided to close the lid (hibernate). When i turned it back on, it did not load. It has a black screen with GRUB written on the top left. I think that grub does not load.My /(root) partition is sda4.Would update grub fix it? (I am worried whether it will find sda4).
View 10 Replies View RelatedOn my laptop, I have stable installed. The original install was about two years ago, and I've just been keeping up with all of the stable updates. It is now an up to date Lenny. Over the months and years I have added several new icon themes to Gnome. I have noticed over time that several of the icon themes' icons have turned up missing. To see what I'm talking about take a look at the screen shots here: [URL]
Screenshot-2 is a closeup.
As you can see, icon themes Amaranth, Crux and Dropline Etiquette are missing their respective theme icons. The icon themes work, when selected, but the icon theme icon in the "Customize Theme" window never appears. Several of the other icon themes are the same. I have tried uninstalling and reinstalling the icon theme packs, but that doesn't fix it. I also have a desktop system of Debian stable with some of the same icon themes as on the laptop, but it does not have this problem. However, it is a much newer installation.
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'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.

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.
Am using Suse 10.2 for internet and e-mail server. currently all my users have access to the internet if they know how to setup their web browsers. how do i deny some users internet access so that a user can only access his/her e-mail but not internet.
