Server :: System Files Delete By Typo - /bin/ Gone _ Recover It?
Jan 23, 2010
I had some bad luck today when I was trying to fix an account that had trouble with FTP. I decided to remove the user and add him again and reset all configuration. Anyhow, to make things short, I accidently typed rm /* -R -f and without looking hit the enter button, as soon as I realised what I wrote I hit ctrl+c. Too bad the /bin/ folder was gone by this time and standard commands like ls didn't execute anymore.
My question is if there is any way to recover these files by a system repair or something? The server is used to host a heavy loaded site which can't afford any downtime, and silly me didn't make a backup of the whole HDD, just the important folders (not the system files).
Currently I don't have the balls to restart the server as I know this will probably turn into a dissaster. I also don't have straight access to this server since it is located in a datacenter (I can go there if absolutely necessary but I rather don't).

before i proceed,I'll like to say that I'm a complete newbie, but enjoying my time with Ubuntu.
Recently, due to hard disk failure, some of the System files got corrupted, I have no idea to which files, but booting Ubuntu from the latest kernel is not working, instead I have to select the previous version from the grub screen.
How to recover these files? Is there a way by which Ubuntu automatically scans and repairs the system files.

My main hard disk died and I replaced it. After installing windows in a small partition in /dev/sda, I thought I will try linux mint and went for it. (I need windows to play AOE, but ubuntu is my primary OS)I didnt see the options properly or some distraction, I choose the "install alongside windows" option probably expecting it to install it in the unallocated partition next to the windows installation. I had completely forgotten my second internal drive /dev/sdb which has the backup data. Linux mint went and installed itself on that drive.
Is there a way to recover individual files from the second harddrive. Now if I boot or open it through live cd, all I see in the linux mint file systems. I want to aleast recover my CV/resume from the second drive. The second drive is a single ext4 file system The old drive is completely dead, it doesnt even get recognized when I attach it to SATA.

When I boot up my Ubuntu system I get the following error message:Install Problem The configuration defaults for Gnome Power Management have been installed incorrectlyI found the following posting and this describes what also happesystemhttps://answers.launchpad.net/ubuntu...uestion/111256I've created a recovery disk by using a memory stick from which I can boot. I can mount the old filesystem (HD). When I navigate, with the file browser, into one of the folder on the the HD and try to delete messages I get the following error message - 'Error removing file: Permission denied'.I guess I need to log / tell those files the root password from the system installation as per the version on the HD. But how do I do this?

I have an external hdd which is formatted with fat for use by both on linux and windows. The issue is that I can't delete some of the files I have which show up with size 0. Also, the modification timestamp (as detected by Krusader, the file manager I am using) is 1935. How can I delete these kind of files without affecting the running fs?

I have some very confidental files on my computer that I store such as credit reports, and other things. I always encrypt them with GPG, but there still is that original non-encrypted file left that needs to be deleted. I looked into tools like wipe, and shred but they all say that it really doesn't help on journaling filesystems directly on their man page.
I am not asking how to wipe the whole drive with dd or anything, but I am simply asking if there is a tool that'll delete a single file securely.

I use Ubuntu 9.04 exclusively on my own machines, but I have a couple of flash drives that got infected by some corrupt windows executable (*.exe) files, probably by somebody's trojan (they are Cruzer 4GB so came with installed fancy programs that I dont need but didnt remove and Windows keeps installing unwanted ini files and other trash every time I use them in somebody elses machine or in an internet cafe). I deleted quite a few files, but some are stubborn.
$ sudo chmod +w-X doesnt seem to work. How do I unprotect and remove them? The filesystem is vFAT.
I suspect the files were created by some kind of a trojan as my work requires my flash to be pretty promiscuous.
When I 've backed up all the good files I need, I'd be happy to reformat the flash drives as straight vanilla data storage and retrieval, provided I can still use them on a variety of machines running MS windows as well as on my Linux machines. Any guidance on reformatting?

I have the cowon iAudio7 music player with vfat file system and increasingly running into permission problems when I try to delete files. Unsurprisingly I am now running out of space. I am figuring if I could somehow mount it onto a folder in my home partition I will have full permissions. The problem is the drives name which is exactly with space: So even if try to delete files in the terminal I don't know how to cd into:
Code:
/media/I AUDIO7
note the space between I & AUDIO7.

Allright, I made a simple script that tarballs my SQL databases weekly and saves them to a backup harddrive.If possible, I would like to have the backups uploaded to a remote server for storage. But, I must have the script delete the previous upload for size contraints.I can only use rsync, scp or sftp. Haven't used any of them really before... Here's my basic tarball-backup script:
Code:
#/bin/sh
# Dates the new tarballs of current builds.
DATE=`date +%m_%d_%Y`

I did something really dumb and accidentally removed the e2fsprog package. Now it deleted all these executables (openssh,scp, yum, etc). If I could just recover the /usr/bin direcotry I was thinking I can reinstall the e2fsprog package. Trying to scp over these executables from other servers won't do because scp and ssh is gone. I still have a sesssion opened right now.

I run 5GBFree.com a free hosting site. As you can imagine, it gets quite a few people signing up to abuse the service.Recently I've found a LOT of people setting up sites with a particular script that floods forums and IRC chat rooms. The names of the files are as follows:
peindom1.php
peindom2.php
peindom3.php
peindom4.php
Is there a command I can run to remove files with these filenames ANYWHERE on the server (so basically, a command to go through all folders on the server and remove instances of that name

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?

I experienced a full hard drive yesterday due to a massive error_log. We took care of the errors, but later found out we were missing files, including a MySQL database table. Having a shopping cart and ecommerce stuff on the site, we found that some of those files were missing, too.Does RHEL 5 have some sort of feature for automatically deleting files when the partition is full? If it does, I want to turn it off.

I am trying to use an old box as backup server. I have tried a couple of possibilities along the lines of:
Quote:
rsync -a --delete --progress --log-file=/home/$USER/info.txt -e ssh /home /etc root@192.168.0.106:/mnt/back
The problem is it does not delete files that has been removed from my local system?
I run the command as root on the local system.
(I realize I should properly not ssh into the server as the server's root but I'm having trouble with the permissions and I want to make sure everything else works before messing around with it)

I have set up a simple find and delete script for files older than X days. The problem is that some of the files that are send in this share are transfered from an archive server and creation/modified date remains the same when copied and the age of them could be a year ago or older and they get deleted over night by the script.For performance reasons the raid is mounted with noatime in fstab.Do you see any solution to this problem except enabling atime?I'm thinking at some more advanced script that writes the list of added files once a day and marks them for deletion after some time.

I just can't stand knowing that there's a slight problem with my PC.I have roughly 12.5 Gigs of files, mostly movies that are multiple clones of a particular movie (which was an entirely different problem altogether) and I CANNOT DELETE THESE THINGS! There has to be a simple way to do it from terminal, problem is, I can't seem to find the trash directory in terminal.

I have (had) Debian Testing running on a 250GB IDE hard drive, partitioned normally.
I also have 4x 1TB drives in a raid 5 using mdadm, and 2x 500GB drives in a raid 1 also with mdadm.
I put the two arrays in lvm using:
I then used "lvcreate" to make storage/backup 300GB, and the rest went to storage/media (approx. 2TB usable). I put an xfs filesystem on both and mounted them.
All was working fine until the system drive shorted out and died on me this morning. As far as I can tell, all my other drives and everything else is fine. I do a daily rsnapshot of the filesystem, which of course is residing on storage/backup (stupid, I know). So I have full backups of everything, but I'll have to put a new hard drive in and reinstall Debian before I can restore everything.
I've reinstalled before and simply reassembled mdadm arrays and remounted them before with no problems, but this is the first time I've used lvm, so I'm not sure what I have to do to restore everything. Is it as simple as reinstalling the system then doing a:

I have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?

There seems to be a typo on Slackware.com security advisory webpage for the updated ssl packages (but not for the actual packages on ftp.slackware.com). The webpage says this:
openssl-0.9.8m-i486-1_slack12.2.tgz
openssl-solibs-0.9.8m-i486-1_slack12.2.tgz
The package in the ftp.slackware.com/12.2/patches/packages repository is:
openssl-0.9.8n-i486-1_slack12.2.tgz
openssl-solibs-0.9.8n-i486-1_slack12.2.tgz
I am guessing its a typo on the webpage because I already have an 'm' installed.

we know that /etc/passwd - is a replica of /etc/passwd file and acts as a backup in any damage done to /etc/passwd file..i have observed a strange thing in RHEL 5.4....for example... if /etc/passwd has 100 accounts.. then /etc/passwd - is having only 99 accounts....when i add 101 useraccount with "useradd" then /etc/passwd has 101 accounts and /etc/passwd is having the 100th account of /etc/passwd - ..when i delete /etc/passwd and recover it with /etc/passwd - from runlevel 1 the lastly created user is not having his account after recovery.. what is the solution? this is same case even with /etc/shadow and /etc/shadow -
