Emacs in Daemon mode

When I started to use emacs as Java IDE, I have installed CEDET and JDEE. This make start time of emacs longer, even when I am not opening any Java file. Therefore, it is required to start Emacs in daemon mode. So that only one time startup is longer, and subsequent startup of emacs (emacs client to be precise) will be much faster.

I have written the following shell script (em, please place it in your $PATH), which starts the emacs daemon on first time only, and connects emacsclient to it. 
#!/bin/bash

usr=$(whoami)
emacs_daemon="emacs --daemon"
cmd="ps auxww | grep \"$usr.*$emacs_daemon\" | grep -v grep"
#echo "$cmd"
is_running=$(eval "$cmd")
if [ -z "$is_running" ]
then
    echo "Starting emacs daemon"
    eval "$emacs_daemon"
    if [ $? -ne 0 ]
    then
        echo "$0: Cannot start $emacs_daemon" >&2
        exit
    fi
fi
emacsclient -a "" -t "$@"
exit $?

First Run: 
$ em Hello.java
Starting emacs daemon

Warning: due to a long standing Gtk+ bug
http://bugzilla.gnome.org/show_bug.cgi?id=85715
Emacs might crash when run in daemon mode and the X11 connection is unexpectedly lost.
Using an Emacs configured with --with-x-toolkit=lucid does not have this problem.

Removing Empty Directories

We can remove empty directories inside a directory by using following command

$ ls -l * | grep -B1 "^total 0K" | grep -v -e "total 0K" -e "--" | cut -d: -f1 | xargs rmdir -v

The above command cannot delete recursively. Hence, using find command to delete recursively.
$ find . -type d -empty -delete

Stopping Tumblerd in XFCE


Tumbler is a D-Bus service for applications to request thumbnails for various URI schemes and MIME types. It is an implementation of the thumbnail management D-Bus specification described here.

  • Issues with Tumblerd: 
    • Using more memory and CPU
    • Preventing removable storage devices from unmounting(then, ejecting)
      • External HDD
      • USB Pendrive
      • CD/DVD 
    • Usually, locking of external devices occur with Video files
$ lsof /run/media/mitesh/PHONE\ CARD
COMMAND   PID   USER   FD   TYPE DEVICE  SIZE/OFF NODE NAME
tumblerd 1268 mitesh    9r   REG   8,17  34902492 1625 /run/media/mitesh/PHONE CARD/video/abc.mp4
tumblerd 1268 mitesh   10r   REG   8,17  69869584 1624 /run/media/mitesh/PHONE CARD/video/def.mp4
tumblerd 1268 mitesh   11r   REG   8,17  35883924 1627 /run/media/mitesh/PHONE CARD/video/ghi.avi
tumblerd 1268 mitesh   14r   REG   8,17 293435929 1629 /run/media/mitesh/PHONE CARD/video/jkl/mno.flv
tumblerd 1268 mitesh   15r   REG   8,17 240015268 1630 /run/media/mitesh/PHONE CARD/video/jkl/pqr.flv

So, in order to get rid of this blocking process tumblerd, we can kill the tumblerd commands given by lsof, as: 
 
$ lsof /run/media/mitesh/PHONE\ CARD/ | awk '{print $2}' | grep -v PID | xargs -L 1 kill -TERM

PS: Please replace /run/media/mitesh/PHONE\ CARD/ with the mount point of the removable device, which is not allowed to be umounted.


If we want to remove this tumblerd, we can give following command:
  • Fedora
    • $ sudo yum remove tumbler
  • Debian/Ubuntu
    •  $ sudo apt-get remove tumbler

Encrypt Directory in Linux

Encrypt Directory

This article describes basic usage of eCryptfs. It guides us through the process of creating a private and secure encrypted directory within our $HOME directory, where we can store all our sensitive files and private data.

In implementation eCryptfs differs from dm-crypt, which provides a block device encryption layer, while eCryptfs is an actual file-system – a stacked cryptographic file system to be exact.

Preliminary Note

In this wiki, I will encrypt a directory /home/mitesh/Private, which is located in /home partition. i.e. /home/mitesh/Private is an ordinary directory and does not use a partition of its own.

Installing eCryptfs

  • eCryptfs can be installed as following:
    • Debian
      • $ sudo apt-get install ecryptfs-utils
    • Fedora
      • $ sudo yum install ecryptfs-utils

Setup

Setup (Simple)

As a user, run the following command: 

$ ecryptfs-setup-private

and follow the instructions.

Setup (Detail)

  • First, we create private directories. 
    $ mkdir /home/mitesh/Private
$ mkdir /home/mitesh/.Private
$ chmod 700 /home/mitesh/.Private
$ chmod 500 /home/mitesh/Private
  • Let's summarize
    • Actual encrypted data will be stored in ~/.Private directory (lower directory)
    • While mounted, decrypted data will be available in ~/Private directory (upper directory)
      • While not mounted nothing can be written to this directory
      • While mounted it has the same permissions as the lower directory
  • eCryptfs can now be mounted on top of ~/Private. 
    $ sudo mount -t ecryptfs /home/mitesh/.Private /home/mitesh/Private
Passphrase: <-- some_passphrase
Select cipher:
 1) aes: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
 2) blowfish: blocksize = 16; min keysize = 16; max keysize = 56 (not loaded)
 3) des3_ede: blocksize = 8; min keysize = 24; max keysize = 24 (not loaded)
 4) twofish: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
 5) cast6: blocksize = 16; min keysize = 16; max keysize = 32 (not loaded)
 6) cast5: blocksize = 8; min keysize = 5; max keysize = 16 (not loaded)
Selection [aes]: <-- ENTER
Select key bytes:
 1) 16
 2) 32
 3) 24
Selection [16]: <-- ENTER
Enable plaintext passthrough (y/n) [n]: <-- ENTER
Enable filename encryption (y/n) [n]: <-- ENTER
Attempting to mount with the following options:
  ecryptfs_unlink_sigs
  ecryptfs_key_bytes=16
  ecryptfs_cipher=aes
  ecryptfs_sig=bd28c38da9fc938b
WARNING: Based on the contents of [/root/.ecryptfs/sig-cache.txt],
it looks like you have never mounted with this key
before. This could mean that you have typed your
passphrase wrong.

Would you like to proceed with the mount (yes/no)? : <-- yes
Would you like to append sig [bd28c38da9fc938b] to
[/root/.ecryptfs/sig-cache.txt]
in order to avoid this warning in the future (yes/no)? : <-- yes
Successfully appended new sig to user sig cache file
Mounted eCryptfs
  • Remember to take backup of /root/.ecryptfs/sig-cache.txt file, if /root partition gets reformatted 
    $ sudo cp -r /root/.ecryptfs /home/mitesh/
  • Verifying mounting of eCryptfs 
    $ mount | grep -i private
/home/mitesh/.Private on /home/mitesh/Private type ecryptfs (rw,relatime,ecryptfs_sig=e8d08163d274c68f,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs)
  • Verifying encryption 
    $ cat ~/Private/test.txt
Some secret text
is present in this file.
$ sudo umount /home/mitesh/Private
$ cat ~/Private/test.txt
cat: /home/mitesh/Private/test.txt: No such file or directory
$ cat ~/.Private/test.txt
-#@%!*^(junk characters)^*!%@#-
  • Mounting without interaction (so passphrase must be in some removable device like USB pendrive) 
    $ sudo mount -t ecryptfs -o key=passphrase:passphrase_passwd_file=/mnt/usb/.ecryptfs-pass,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_passthrough=n,ecryptfs_enable_filename_crypto=n /home/mitesh/.Private /home/mitesh/Private
$ cat /mnt/usb/.ecryptfs-pass
passphrase_passwd=ThisIsAWeakPassword

Encrypting Other Directory

  • We can encrypt multiple directories, by putting those directories into /home/mitesh/Private and creating soft-links. 
    $ mv ~/Documents ~/Private
$ ln -s ~/Private/Documents ~/Documents
  • By following the above 2 steps, we have encrypted directory ~/Documents .

Unmount

$ sudo umount /home/mitesh/Private

Auto Mounting of Debian Offline Repository ISOs

If you are not connected to internet, then still you can install packages from Debian Installer ISOs.
For example, if Debian 6.0 (Squeeze) ISOs are in directory 
/media/FreeAgent GoFlex Drive/Softwares/Debian_6_0/
directory and we want to mount these iso in 
/mnt/Debian/
directory. The following command can be used: 
$ sudo $(which mount_debian.sh) /media/FreeAgent\ GoFlex\ Drive/Softwares/Debian_6_0 /mnt/Debian
The shell script mount_debian.sh is given below.
You need to reload the debian repository (if internet repository is used before this command), to take packages from these mounted ISOs. Because the /etc/apt/sources.list is backed up and updated with these mounted ISOs.
$ sudo apt-get update

In order to, unmount the ISOs, the following command can be given: 
$ sudo $(which umount_debian.sh) /mnt/Debian/
This command will recover original /etc/apt/sources.list 
mount_debian.sh

Encrypt Partitions with dm-crypt LUKS


Encrypt Partitions with dm-crypt LUKS

These instructions use the Linux dm-crypt (device-mapper) facility available on the 2.6 kernel. In this example, lets encrypt the partition /dev/sdc1, it could be however any other partition or disk, or USB or a file based partition created with losetup. In this case we would use /dev/loop0. The device mapper uses labels to identify a partition. We use sdc1 in this example, but it could be any string.

dm-crypt with LUKS

LUKS with dm-crypt has better encryption and makes it possible to have "multiple passphrase" for the same partition or to change the password easily. To test if LUKS is available, simply type

# cryptsetup --help

if nothing about LUKS shows up, use the instructions below Without LUKS. First create a partition if necessary:

# fdisk /dev/sdc

Create encrypted partition

# dd if=/dev/urandom of=/dev/sdc1          # Optional. For paranoids only (takes days)
# cryptsetup -y luksFormat /dev/sdc1       # This destroys any data on sdc1
# cryptsetup luksOpen /dev/sdc1 sdc1
# mkfs.ext3 /dev/mapper/sdc1               # create ext3 file system
# mount -t ext3 /dev/mapper/sdc1 /mnt
# umount /mnt
# cryptsetup luksClose sdc1                # Detach the encrypted partition

Attach

# cryptsetup luksOpen /dev/sdc1 sdc1
# mount -t ext3 /dev/mapper/sdc1 /mnt

Detach

# umount /mnt
# cryptsetup luksClose sdc1

Using multiple passphrase for same partition

We can store another password in a file (say ~mitesh/temp/key_file.txt) and use it. 

# cryptsetup luksAddKey /dev/sdc1 ~mitesh/temp/key_file.txt 
Enter any passphrase: 
# cryptsetup luksOpen --key-file  ~mitesh/temp/key_file.txt /dev/sdc1 sdc1

dm-crypt without LUKS

# cryptsetup -y create sdc1 /dev/sdc1      # or any other partition like /dev/loop0
# dmsetup ls                               # check it, will display: sdc1 (254, 0)
# mkfs.ext3 /dev/mapper/sdc1               # This is done only the first time!
# mount -t ext3 /dev/mapper/sdc1 /mnt
# umount /mnt/
# cryptsetup remove sdc1                   # Detach the encrypted partition

Do exactly the same (without the mkfs part!) to re-attach the partition. If the password is not correct, the mount command will fail. In this case simply remove the map sdc1 (cryptsetup remove sdc1) and create it again.

Command Line Dictionary : meaning of

If we have only console, and we want to quickly see meaning of some word. Then we can use following perl script to get dictionary meaning of a word. It uses perl, curl and html2text.
The source code of meaning_of.pl is : 
#!/usr/bin/perl -w

## Search the dict.org

use strict;
use warnings;

sub print_usage() 
{
    print STDERR "USAGE: $0 <query>\n";
}

if (@ARGV < 1)
{
    &print_usage();
    exit(-1);
}

my $query = "$ARGV[0]";
$query =~ s/ /\%20/g;

my $cmd = "curl -# -A \"Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)\" -d \"Form=Dict1&Query=${query}&Strategy=*&Database=english\" \"http://www.dict.org/bin/Dict\" | html2text 2>/dev/null";
#system($cmd);
#exit($?);

open(MOFH, "$cmd | ") or die("$0: cannot execute: $cmd\n");

my $skip_lines = 10; # skip first 10 lines
my $line;
while ($line = <MOFH>)
{
    --$skip_lines;
    next if ($skip_lines > 0);
    chomp($line);
    print "$line\n";
}
close(MOFH);

exit(0);
Sample run of above perl script :

$ meaning_of.pl happiness 

######################################################################## 100.0%
===============================================================================
4 definitions found for happiness
From The_Collaborative_International_Dictionary_of_English_v.0.48:

  Happiness \Hap"pi*ness\, n. [From Happy.]
     1. Good luck; good fortune; prosperity.
        [1913 Webster]

              All happiness bechance to thee in Milan! --Shak.
        [1913 Webster]

     2. An agreeable feeling or condition of the soul arising from
        good fortune or propitious happening of any kind; the
        possession of those circumstances or that state of being
        which is attended with enjoyment; the state of being
        happy; contentment; joyful satisfaction; felicity;
        blessedness.
        [1913 Webster]

     3. Fortuitous elegance; unstudied grace; -- used especially
        of language.
        [1913 Webster]

              Some beauties yet no precepts can declare,
              For there's a happiness, as well as care. --Pope.

     Syn: Happiness, Felicity, Blessedness, Bliss.

     Usage: Happiness is generic, and is applied to almost every
            kind of enjoyment except that of the animal appetites;
            felicity is a more formal word, and is used more
            sparingly in the same general sense, but with elevated
            associations; blessedness is applied to the most
            refined enjoyment arising from the purest social,
            benevolent, and religious affections; bliss denotes
            still more exalted delight, and is applied more
            appropriately to the joy anticipated in heaven.
            [1913 Webster]

                  O happiness! our being's end and aim! --Pope.
            [1913 Webster]

                  Others in virtue place felicity,
                  But virtue joined with riches and long life;
                  In corporal pleasures he, and careless ease.
                                                    --Milton.
            [1913 Webster]

                  His overthrow heaped happiness upon him;
                  For then, and not till then, he felt himself,
                  And found the blessedness of being little.
                                                    --Shak.
