I think I did something dumb. I was trying to increase the space allocation to my /home virtual disk on my wubi installation of Ubuntu. I ran the wubi-add-virtual-disk utility (as I had done before the first time I increased my space), but I received the message "The target virtual disk /host/ubuntu/disks/$virtual_disk already exists, aborting." So, thinking that all my data was in a different path and that the file home.disk was probably just some configuration file of little importance (I should've checked and I should've made a backup of it myself), I browsed to /host/ubuntu/disks and ran "rm home.disk", then reran the wubi-add-virtual-disk utility (stored in my still existing /home/cportiz/Downloads directory), and I thought I had successfully increased my space.
To my horror, upon restarting my computer, my desktop was empty and basically unusable as there is nothing to click on. I rebooted on recovery mode and logged on in terminal mode, then browsed to /home and found an EMPTY folder. I ran locate home.disk and found a file at /host/ubuntu/disks with the size that I specified when I ran the virtual disk utility, but I don't know where my old contents are. I didn't just delete all that stuff. it is still somewhere on my hard drive and that all I need to do is modify the home.disk file in this or that way or hit restore. There is not a home.backup file at /host/ubuntu/disks/.
Anyhow, if indeed I've lost everything, I can probably restore most of the work I'd done (only a couple of weeks worth) pretty quickly. Some of the files were backed up in other computers, etc... How to restore my wubi installation to a functional one? I would prefer not to have to reinstall ubuntu altogether since I believe the majority of the packages I've installed were housed on /opt meaning I can get back up and running compiling certain programs from source fairly quickly and most of the recovery effort is in rewriting some of the files that were stored in /home.

Recently I setup a system for a non-technical user. He is only using Firefox, Pidgin and OpenOffice for about 2 hours a day. I have created a folder "/home/jim/myFiles" where he can save his document files. But Jim has accidentally deleted his myFiles folder on 2 occasions. He had intended to delete a file in that folder. Is there a way to lock the folder so that the user and create/read/write documents in that folder but not delete the folder itself?

3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?

I am having a problem with my login labeled "mysql" with the command # groupadd mysql# useradd -g mysql is is of course all within the confines of being super user. What I am having trouble with is that I cannot delete the user through the terminal using the command userdel but to no avail, it states that the user mysql is still logged in even though I have restarted the computer and logged in only to my root account.Whenever I try to log into mysql account it gives me multiple error messages something about the ICE authority and nautilus and when i get past these and onto the home screen, there is nothing, the wallpaper is there but there are no icons and no tool-bars, I cannot shutdown or get to a terminal while on the dysfunctional user. I cannot delete the user because it states I am logged in even though I am not.

Ever since I upgraded from karmic to lucid my user account has been really buggy. The other profiles on the computer are acting normal but I believe mine is acting strangely because of the way I had my desktop set up before I upgraded (conky and a terminal on my desktop, compiz). Is there a way to reset my account to the default settings? I figured if I could delete my account and recreate it everything would be okay but I can not delete the account.

I accidentally chmodded my entire /etc/ folder to 755 privileges.
It's not completely critical because my system is a home server.
My biggest problem is that MySQL is pitching a start-up message saying that I have 'unprotected key file', clamav is stating that it won't start until it has owner permissions...
I did chmod 600 /etc/passwd just in case.
"How do I see all the start-up complaints in a text file?"

way to automate adding and removing users from 10 different Fedora 7 servers. We use them as print servers and our users have a user name and password to authenticate with when printing. We also use Samba to talk to a W2k3 server that tracks and charges the users for what they print. The set up was done by a vendor and after 6 months of being in production the scripts they created has flaws.
I need a way for a script to run as often as possible that will remove, change, or delete user accounts from the servers and from Samba. how to most effectively achieve this?
It would be ideal to have a file that gets written to when a change needs to be made then a script to make these changes?

I run a server where multiple people can access it via SSH and have access to the same folder. Someone recently decided to stop using my server so I deleted their login account inside the User and Group GUI inside gnome. I accidentally selected delete files owned by this user. I didn't think much of it because the user didn't actually own any of the files since it was shared among all of them. Anyway, ALL the files in that shared home directory vanished, including the home directory. How can I recover this? It didn't move all the files to the root trash or my local user's trash folder. Are the permanently deleted?

Any program that has a web interface and has a features such as adding, deleting users as well as changing password. If none, does anyone knows a program that can interact with a script. A java page or apache+php perhaps? I can create script for those features but my problem is how can I integrate it to a GUI.

I just erased +200GB worth of photos, documents, music and videos on my external hard drive.I wanted to try the new Ubuntu Lucid Lynx Alpha 2, so I downloaded the .iso, launched the live USB disk creator and tried to format my 1GB pendrive to make room for the OS. Somehow, I ended formatting my 320GB external USB hard drive. The hard drive had to partitions (one EXT3 and one NTFS), but now it only has a FAT partition that spans the whole drive.I understand that the new FAT partition may have erased the EXT3 data structures at the beggining of the partition, making file recovery next to impossible.A confirmation dialog on the live USB disk creator wouldn't have hurted either.

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 accidentally deleted all the files from file system in my hard drive (thankfully not my /home since it resided on a separate hdd). I did this from another system while I had connected that hdd to look at some files since my system was not booting correctly. The problem is that I deleted everything (manually while I was in nautilus) including the .Trash file. I have not formatted this drive so the partition table remains the same, nor have I written anything to it since the deletion, and, this drive is using ext4. What is the best way to restore this drive to how it was (say yesterday at 4:30PM)? (I have a lot of programs installed and I have been upgrading Ubuntu there since 9.04 to now 10.04). If I am not mistaken when data is deleted in ext4 it is simply flagged as usable space, and if that is so, is it possible to just simply unflag this data to get every file back the way it was yesterday at 4:30PM?

I have been working on this script and I just made a ridiculous error. I tried to move my script out of my home directory and for some reason I put in "mv myscript .bashrc" Now my .bashrc file has nothing but my script in there... I think I may have overwritten some important info. Is running cp /root/.bashrc ~

I just wanted to post this in case it helps anyone else. I have all my personal files (photos, documents, etc.) saved on a separate ext3 partition (so I don't have to worry about them on new installs, etc.). When I tried to delete files, however, I always received the message: "Cannot move file to trash, do you want to delete immediately?".
After much searching and failed fix attempts (mostly unnecessary messing with fstab), I found this post, which is now archived (or I would have replied there):ttp://ubuntuforums.org/showthread.php?t=759544. And frediE's solution, with a couple tiny modifications, finally solved the problem! (So huge thanks to frediE! ). irst, I found my user id, which is 1000, by going to the System > Administration > Users and Groups menu, selecting my user name (e.g. jnewm), clicking "Properties", andselecting "Advanced".
Second, I created a folder on the root of my partition called ".Trash-1000". (I may have needed to use "gksu nautilus" from a terminal to create the folder, I don't recall.)Third and last, I navigated to the root of the partition in my terminal and ran: sudo chown -R jnewm:jnewm .Trash-1000. Followed by: sudo chmod -R jnewm .Trash-1000 (I doubt this second step was necessary, but I'm listing it just in case). (confirmed unnecessary)

We are looking to monitor and log selected application file systems for file create/modify/delete changes that will also include, user account that changed/deleted the file, file name and date and time of event. Everything I have looked at does not seem to provide all of the information that we need.Inotify seems to monitor modify/create/delete but does not seem to provide the user account. Auditd seems to monitor modify/create/append with user account, but not deletes.We need to provide this information to auditing for Sarbane Oxley compliance.

There's a physical problem with my Microsoft mouse (and from what I've heard many other Microsoft and Logitech mice) where it accidentally double clicks during what is intended to be one click from me. I was thinking that surely some software that ignores the next click input from the mouse if it is within say 50ms (At a guess) as the last click would solve this problem and increase the longevity of these mice. Is there an option for this somewhere? Perhaps it would be easy to program a simple script or something for this?
