1.  Introduction

This month in the GMN

Welcome to the July issue of the Gentoo monthly newsletter!

As usual, you can discuss any aspect of this issue of the GMN in the corresponding forum thread. We look forward to hearing from you!

2.  Gentoo News

2008.0 Released!

Since our last issue, Gentoo Linux 2008.0 has been released. Remember, releases are mostly made to satisfy new users. Existing Gentoo users don't need to reinstall; your system can be kept up-to-date just by running emerge --sync && emerge -avtuD world.

Security Meeting Summary

The Gentoo Security Team held a meeting on July 14, 2008. The meeting included a short overview of the security project's status, what can be improved, how to handle delays in GLSA publication and bug resolution, and the supported status of games. The project is actively seeking help; if you have an interest, please contact the team.

Trustees Meeting Summary

The Gentoo Trustees held its monthly meeting on July 13.

Council Meeting Summary

The Gentoo Council held its monthly meeting on July 10, 2008. The items put up for discussion were:

  • GLEP 54: There were numerous questions that apparently were not brought up on the mailing list in advance or were not addressed.
  • GLEP 55: On hold pending a concrete requirement for it. GLEP 54 may be, but that's unclear until it's been revised.
  • GLEP 56: Approved. Cardoe will get repoman changes made, followed by a server-side script to generate use.local.desc from metadata.xml.

Coming Up

  • Bugday: Looking for a way to help out Gentoo without investing a lot of time? Join us on August 02 for our monthly bugday, and help us squash some bugs.
  • Council Meeting: The Gentoo Council meets twice every month to discuss important technical issues that affect Gentoo as a whole. The next meeting is scheduled to be held on August 14, and everyone is welcome to participate - #gentoo-council on irc.freenode.net at 2000UTC.
  • Trustees Meeting: Scheduled for August 19 (agenda). Updated bylaws have also been posted, and public discussion is solicited on the gentoo-nfp mailing list.

3.  Heard in the Community

Gentoo at Peel Fresco Music Lounge

Peel Fresco Music Lounge is a bar in the heart of SoHo, Central, Hong Kong. This bar is different from others -- it uses lots of open source software, and Gentoo Linux lies at the heart of the software stack.

Peel Fresco has set up a page listing their OSS, and how they use Gentoo.

4.  Tips and Tricks

Recovering Deleted Files

Have you ever accidentally deleted a file or files and wanted to bring them back? If so, this guide will show you a method for trying to recover just about any deleted file.

First, we need to consider a number of factors:

  1. Size of the partition where the file was deleted. If your partition is very large and you can't copy the entire thing to another partition, then you will have to risk losing data on the partition with the deleted file. If you decide to take this risk, then skip the second step that follows.
  2. The type of file you deleted, e.g. a vital file needed to follow this guide or something on your thumb drive. If you deleted something like /usr/bin/dd or /usr/bin/cat as well as /bin/dd and /bin/cat, then you will probably need to boot from a LiveCD or another Gentoo installation. You can try to copy these vital files over (or you can just follow this guide), but manually install all of the programs Portage will want to install.
  3. The filesystem of the partition. If your partition's filesystem is anything other than FAT, Ext2/3, NTFS, UFS, or ISO 9660, you will not be able to use the tool covered in this guide.

After considiring these factors, let's make a block-for-block copy the of the partition:

Code Listing 4.1: Making a block-for-block copy

(Replace part with the partition from with you want to recover the file)
# dd if=/dev/part of=/var/tmp/recovery-img

Let's install sleuthkit:

Code Listing 4.2: Installing sleuthkit

# emerge sleuthkit

Next, create a small script, reconstruct.sh:

Code Listing 4.3: Creating reconstruct.sh

#!/bin/bash
# reconstruct.sh -- reconstruct lost but not overwritten FAT data

cat $1 |
  while read line; do
    filetype=`echo "$line" | awk {'print $1'}`
    filenode=`echo "$line" | awk {'print $3'}`
    filenode=${filenode%:}
    filename=`echo "$line" | cut -f 2`

  echo "$filename"

  if [ $filetype == "d/d" ]; then
    mkdir -p "$filename"
  else
    icat -f $2 -r -s $3 "$filenode" > "$filename"
  fi
  done

Now let's make sleuthkit give us a list of files that were deleted:

Code Listing 4.4: Listing deleted files

# fls -f ext -d -p -r /dev/part

Note: If you are working with a FAT-formatted partition, replace ext with fat. Likewise with NTFS, replace ext with ntfs. In this case, the guide assumes the filesystem is either ext2 or ext3. Replace part with your partition.

You should get a list of files like this:

Code Listing 4.5: Deleted files

# fls -f ext -d -p -r /dev/part
r/r * 24590:    whoops_im_a_deleted_file

Warning: If you deleted a file and have not unmounted your partition yet, fls will not show you that file. Unmount the partition first.

Assuming we want to recover whoops_im_a_deleted_file, we do the following:

Code Listing 4.6: Using reconstruct.sh to recover a file

# fls -f ext -d -p -r /dev/part | grep "whoops_im_a_deleted_file$" > recover_files_list
# sh reconstruct.sh recover_files_list ext /var/tmp/recovery-img

You may also do without the grep command and modify the files list yourself. Once again, replace ext with the filesystem that you are working with.

You don't have to use the script; you can also simply run the following:

Code Listing 4.7: Recovering a file without reconstruct.sh

# icat -f ext -r -s  /var/tmp/recovery_img 24590 > whoops_im_a_deleted_file_recovered

Note: icat is not guaranteed to work all the time. It will try various recover techniques, but none of them might work. Nevertheless, this guide presents a "first-try" method for getting your lost files back.

This edition of Tips and Tricks was inspired by this forum post by der bastler.
