Our system is based on RH4 and is using pam_tally and faillog to record failed attempts and to lock users out after 5 attempts. We have a requirement to provide a normal (non-root) user logging onto our system, with information regarding the number of failed logon attempts made on their account before the current successful logon (similar to the functionality provided by HP Protect Tools on Windows). My first idea was to add 'faillog -u $USER' to the bashrc, however by the time the bashrc is run - the user has been successfully authenticated and the faillog has been reset back to zero.

I have a fileserver running debian 6 and I would like to be able to remote control it over VNC. I have enabled Remote Desktop in Gnome and it works, however I have to be logged into Gnome for it to work. Gnome doesn't enable vino before a user is logged in for some reason. This presents a problem as there is no keyboard or mouse connected letalone a screen.
I looked up the issue on google and found this: [URL] Long story short, I have to edit /etc/gdm/Init/Default and insert "/usr/lib/vino/vino-server &" just before 'exit 0' at the end of the file, and change "KillInitClients" to "false" in /etc/gdm/gdm.conf. I edited the first one as it says, but I can't find gdm.conf anywhere. I did however find a 'daemon.conf' in the /etc/gdm directory, and added the line there.
When I try to connect after doing the above, my vnc viewer (client) just disappears - no errors, message, sound - nothing. It doesn't even ask for a password. I checked the comments in the link, and the second to last comment suggests it's because of some negotiating-issue which should be an easy fix:
Turned out I had to enable connections to vino not related to my user account. To do this run sudo vino-preferences and duplicate the settings instructed here

I have been running Lenny with the non-free nVidia drivers for a while now, but decided to run testing RC2.When I was done my monitor had a solid blue-gray background and the mouse pointer, but none of the GUI parts displayed (blank). After a couple of checks I went back to the gdm logon screen and opened 'sessions' to _not_ find Gnome as one of the choices. So I logged into Gnome(failsafe) and got my full GUI.Console (F1) and xterm also work fine.Trying to get my Gnome Desktop back. GDM is working and I have the session choice for TWM, but with Gnome(failsafe) working I haven't tried it yet to see if it works.

I've been a Linux user for 11 years. I'm not new to the ways of live cd's. I am unable to get past the logon screen in Debian Live.
I have tried "live" for the user name without a password - and with root as a password. NOTHING I've tried works.
Anybody got an idea?

I have a Debian etch system I haven't fired up for about a year because the mobo went bad.I had one user setup, I hammered it with all my normal passwords and finally got a prompt that said 'Access Denied'So my understanding is that I figured out my PW, but for some reason this user doesn't have access anymore.Is there a workaround for this? I am just trying to retrieve some files from the drive I don't have a problem formatting it.
Also I tried hooking it up to a windows machine:I loaded Ext2 IFS, it recognizes the drive, but says it can't load it - something to do with the headers being closed out improperly, and basically said I would have to boot it in linux then try it in windows.I tried this after I got to the linux logon prompt (the bootloader had scanned the drive because it hadn't been scanned for x amount of days), this didn't help Ext IFS read the drive.

This all started when I had no sound being detected by my laptop's mic. I also have an external USB sound card and it was not detecting mic sound either. I had previously done recording with Audacity (it could have been back in Ubuntu 8.04).
Now, I had a feeling that I was going to break something trying to get the mic to work. Sure enough, I'm at the point now where I cannot logon to the GUI (gdm).
I made a number of changes before my last reboot.
Here's a summary of what I think is the primary cuase (pulseaudio!):
At one point, I had lost sound altogether (I believe this was a result of having installed pulseaudio Volume control, which someone used to unlock and configure their mic).
So, things were starting to degrade. Being the persistant and stubborn one that I am, I decide to trudge on.
I had read enough suggestions (and desite enough "didn't fix" responses), I decided to try removing pulseuadio altogether. After rebooting, I was not able to log on.
Let me try to describe this logon situation as clearly as possible: When the laptop boots up, it shows the Ubuntu logo with the colored dots below moving from right to left (orange/white).
When I get to the user logon screen, it's not as fancy as it normally is. The logon window which allows me to select the user is a little more basic and the background is a simple black/purple color. The day and time is displayed on the task bar below as well as a power icon with options to suspend, restart and shut down.
This is how the logon screen used to look:[url]
I've been unable to find a screenshot of the current state and I don't think I'll be able to post one due to my technologically limited situation.
When I select my user and enter the password, The screen goes blank (or displays what appears to be the console for CTRL+ALT+F1) and then I'm back at the user selection as described above as if I hadn't even tried to log on.
At this point, I'm not positive which distro I'm using, nor which kernel, but survey says:
My laptop is a Pavilion zd8000.
lspci shows I have: VGA compatible controller: ATI Technologies Inv M22 [Mobility Radeon X300]
I'm not sure if this is proper. When I run /etc/init.d/gdm stop, I get: Rather than invoking init scripts through /etc/init.d, use the service( utility, e.g. service gdm stop.
Probably not, because when I try sudo service gdm stop, it returns: stop: Unkown instance.
OK. Maybe it's OK, because running sudo service gdm start, I returned back to the logon screen. (But, I'll include this because it may indicate something, but I think it may be the way the "service" works now...)
(I do have networking enabled, so I can run apt-get and what not)
I find this interesting. I installed kdm. I started it after stopping gdm (through the service command as noted above). I was able to log on through kdm, but I'm not brought to a desktop, only a black background and a terminal window in the upper-left corner, without any window frames (I can't min/maximize/close). There doesn't appear any way to log out...
I'm not exactly sure where to go from here. I'm getting more interested in a backup/reinstall, but I may not have the ability to do that on hand, so I'd like to try to get things working. At the very least, I'd like to be able to log on and do work. Sound would be nice and a working mic would also be nice, but I can do without either of those two for now.
Most of the solutions I've been able to find in terms of not being able to log on has been a result of:
- Bad usernames/passwords
- Insufficient drive space to allow logon
While I haven't tried creating any new users and logging on with them, I'm confident it wouldn't do any good. df -a shows: /dev/sda1 Available = 6324296. Should be enough for basic operations.
My plan at this point is to start woking on the kdm angle. Since I am able to log on, but only to a terminal window, perhaps I can find some info on why that happens...

I have 6 disks (partitions) combined into one lvm volgroup in my server. The server have been online for a year.
And today, suddenly it hangs. At first, I thought it's caused by network lag, because after a couple minutes the server is responsive again. But then I felt something very wrong. I can't access any file that stored on the lvm.
After some dmesg, fdisk -l and a peek at /etc/lvm/archive/*, I found that one of the partitions used for lvm volgroup is missing. Tried a reboot, and the suspected disk is undetected even in BIOS. Must be caused by bad block on the disk's sector zero or something. I think missing one pv makes the volgroup failed to initiate. So, no volgroup, no logical volume. And I can't access the files on it for sure.
Is there a way I can save/rescue data from other non-damaged disks? I have no luck finding similar situation (and solution) by searching on google.

I was trying to delete a logical drive in windows xp and the damn disk management tool in windows not only deleted my other windows partition but also my linux /data ext3 partition. Now I have a unallocated space in place of these partitions. The data is still there but the entries in the partition table have been removed. So how do I recover my partition. I was trying to use the following tutorial. [URK]
I used the sudo parted /dev/sda -- and then rescue START END command and could get back the /data partition. But it gives me the following error while mounting the partition. mount: wrong fs type, bad option, bad superblock on /dev/sda7, missing codepage or helper program or other error. In some cases useful info is found in syslog - try dmesg | tail or so.
What does this mean. How to I fix this? Also when I try to recover my windows partition using parted it scans for a while and then does nothing. It doesnot ask for writing the lost partition in the partition table. What do I do?

I use an android app (Exif4film) for recording EXIF data (only aperture, shutter speed) when shooting an old analog full-manual film camera.
Everytime i take a shot, i dial in the app the shutter speed and aperture settings. Later i want to see if my settings were right.
The app exports an xml file. What software should i use to extract the exposure settings and to put them on the corresponding picture?

I've installed F15 but due to the old age of my tablet (HP TC1100), I cannot logon to Gnome 3. It say something like "Opps, sorry something went wrong..." and then puts me back to the logon prompt. Is there any way I can logon to Gnome using the old layout? I installed KDE during install but couldn't find anything that would allow me to change how I logon to Gnome.

#!/bin/sh
ifconfig eth0 | grep "inet addr:" | awk -F'inet addr:' '{print $2}'
which is located in the /etc/init.d directory. changed the permissions to make it executable: chmod +x displayip then ran update-rc.d displayip defaults which ran successfully. Upon boot it doesn't show up with anything.

Hey currently running Lucid x64. After installing tex-common due to there being errors on all app installations (the apps all seemed to work fine though). I am unable to proceed past the GUI logon, the screen just goes black and returns back to the logon screen. I should also note that the PC was setup to automatically login, so it shouldn,t ask me to logon any way.
I had installed many updates earlier that day and also the nvidia graphics driver (before updates), rgba gtk+ module, gnome-color-chooser and upgraded nautilius. All which where working fine at the point before tex-common installation.

I recently decided to get back into Ubuntu and installed 10.10 on my Acer Aspire 7741Z. The live USB worked great but the installed OS won't load the GUI. The loading screen does not show but instead there is a ton of text. The logon is the 'standard' logon (Ubuntu 10.10 -computer name- tty1). I can logon using the account information that the graphical installation asked for. After awhile, the screen goes blank. Pressing the power button, the text comes back and Ubuntu the message "ppdev: user-space parallel port driver" has appeared. Using "startx" causes the screen to go blank, and the screen comes back when the power button is pressed before shutting down.

This afternoon, I tried to change the password, for the windows access via Samba, but I goofed.
While logged in with a Putty session, I typed code...
It asked me for the new password after the first line, then again after the second line as expected.
In retrospect I probably should not have typed the first line.
Now, however, I can't log in via putty. When I attempt to, it asks for my password, but neither the new nor old password works.
I DO have access to the Samba shares from other windows machines using the new password so that is OK.
It is a non GUI 10.04 server with one user, mark.
Help, please, how do I fix it?
Ideally, I guess I want the old password for the log in, but the new password for Samba shares.

I put in my root username peter and the password that I use for mysql which I also used when I setup phpmyadmin. I get an error message: "#1045 - Access denied for user 'Peter'@'localhost' (using password: YES)"Do I need to add something to a config file somewhere?

I have been using Wheezy for two years, and everything was OK, so I decided to upgrade to Jessie. In fact i decided to perform a clean install of jessie, so I formatted the partition where Wheezy was installed, and the /boot partition, and I installed jessie in those partitions.
As I had done with Wheezy, I installed jessie in an encrypted LVM, and the installation was ok (well, almost everything was OK, because grub and plymouth were not working, but I will open another topic about it).
First thing I did after installing Jessie was editting sources.list in order to download a few programs (plymouth, firmware linux non free, libdvdcss2, gufw, menulibre). Moreover, I downloaded a few progrmas from the Debian install DVD (flashplugin, VLC, chromium, clamav). i did not perform a dist upgrade because i was not at home, and where I was I did not have a Wifi connection (so I was using my mobile connecion -USB ethernet with an android phone-. BTW I had just performed a hard reset I had not installed any apps after that, so that mobile phone was "clean").
After that, I created a desktop user account, and I rebooted the laptop . When i rebooted, I started to tweak my user account: I edited dconf, and the gnome shell theme; and I started my mobile connection to download three extensions for gnome shell (window list, simple dock and activities configurator. I had used those extensions with Wheezy, and I had never had any problems). Ten minutes after I started the mentioned mobile connection, I reveived a SMS as I had used over 300 MB. Gnome monitor showed that I have downloaded 300 MB, and the android native data usage app showed the same. I did not download any video or music neither watch any videos on youtube, dailymotion..., I did not visit any suspicious web
I had a look at the apt logs and I din not find anything significant (I was using a no sudo user account, so i was not able to perform a dist.upgrade), I had a look at the download, video, music, picture folders and i din not find anything. I tried to check the iceweasel cache folder, but there were so many subfolders I could not check everything.
