Plowshare

Introduction

Plowshare is a set of command-line tools (written entirely in Bash shell script) designed for managing file-sharing websites (aka Hosters).

Plowshare is divided into 6 scripts:

• plowdown, for downloading URLs
• plowup, for uploading files
• plowdel, for deleting remote files
• plowlist, for listing remote shared folders
• plowprobe, for retrieving information of downloading URLs
• plowmod, easy management (installation or update) of Plowshare modules

Plowshare itself doesn't support any websites (named module). It's just the core engine. Concerning modules, few are available separately and must be installed in user directory (see below).

Features

• Small footprint (few shell scripts). No java, no python. Run fast on embedded devices.
• Few dependencies and portable. Bash and cURL are enough for most hosters.
• Modules (hoster plugins) are simple to write using Plowshare API.
• Support for automatic online captcha solver services.
• Cache mechanism: hoster session or cookie reuse (to avoid relogin).

Install

See INSTALL file for details.

Usage examples

All scripts share the same verbose options:

• -v0 (be quiet, alias: -q)
• -v1 (errors only)
• -v2 (infos message; default)
• -v3 (show all messages)
• -v4 (show all messages, HTML pages and cookies, use this for bug report)

Getting help:

• --help
• --longhelp (additionally prints modules command-line options)

Exhaustive documentation is available in manpages.

All examples below are using fake links.

Plowdown

Download a file from Rapidshare:

$ plowdown http://www.rapidshare.com/files/86545320/Tux-Trainer.rar

Download a file from Rapidgator using an account (free or premium):

$ plowdown -a 'myuser:mypassword' http://rapidgator.net/file/49b1b874

Note: : is the separator character for login and password. Enclosing string using single quotes ensure against shell expansion.

Download a list of links (one link per line):

$ cat file_with_links.txt
# This is a comment
http://depositfiles.com/files/abcdefghi
http://www.rapidshare.com/files/86545320/Tux-Trainer_25-01-2008.rar
$ plowdown file_with_links.txt

Download a list of links (one link per line) commenting out (with #) those successfully downloaded:

$ plowdown -m file_with_links.txt

Note: Files are consecutively downloaded in the order read from input text file.

Download a file from Oron with Death by Captcha service:

$ plowdown --deathbycaptcha='user:pass' http://oron.com/dw726z0ohky5

Download a file from Rapidshare with a proxy (cURL supports http_proxy and https_proxy environment variables, default port is 3128):

$ export http_proxy=http://xxx.xxx.xxx.xxx:80
$ plowdown http://www.rapidshare.com/files/86545320/Tux-Trainer.rar

Download a file with limiting the download speed (in bytes per second):

$ plowdown --max-rate 900K http://www.rapidshare.com/files/86545320/Tux-Trainer.rar

Note: Accepted prefixes are: k, K, Ki, M, m, Mi.

Download a file from Rapidshare (like firefox: append .part suffix to filename while file is being downloaded):

$ plowdown --temp-rename http://www.rapidshare.com/files/86545320/Tux-Trainer.rar

Download a password-protected file from Mediafire:

$ plowdown -p 'somepassword' http://www.mediafire.com/?mt0egmhietj60iy

Note: If you don't specify password and link requests it, you'll be prompted (stdin) for one.

Avoid never-ending downloads: limit the number of tries (for captchas) and wait delays for each link:

$ plowdown --max-retries=4 --timeout=3600 my_big_list_file.txt

Retrieve final url (don't use plowdown for download):

$ plowdown -q --skip-final --printf %d http://oron.com/dw726z0ohky5 | xargs wget

Note: This will not work if final url (remote host) requires a cookie. For anonynous users, generated link has limited access in time and you can usually download file only once.

Plowup

Upload a single file anonymously to BayFiles:

$ plowup bayfiles /tmp/foo.bar

Upload a bunch of files anonymously to 2Shared (doesn't recurse subdirectories):

$ plowup 2shared /path/myphotos/*

Note: * is a wildcard character expanded by Bash interpreter.

Upload a file to Rapidshare with an account (premium or free)

$ plowup -a 'myuser:mypassword' rapidshare /path/xxx

Upload a file to Mirrorcreator changing remote filename:

$ plowup mirrorcreator /path/myfile.txt:anothername.txt

Note: : is the separator character for local filename and remote filename.

Upload a file to MegaShares (anonymously) and set description:

$ plowup -d "Important document" megashares /path/myfile.tex

Upload a file to Oron anonymously with a proxy:

$ export http_proxy=http://xxx.xxx.xxx.xxx:80
$ export https_proxy=http://xxx.xxx.xxx.xxx:80
$ plowup oron /path/myfile.txt

Abort slow upload (if rate is below limit during 30 seconds):

$ plowup --min-rate 100k mediafire /path/bigfile.zip

Modify remote filenames (example: foobar.rar gives foobar-PLOW.rar):

$ plowup --name='%g-PLOW.%x' mirrorcreator *.rar

Remark: cURL is not capable of uploading files containing a comma , in their filename, but plowup will temporarily create a symlink for you.

Use cache over sessions to avoid multiple logins:

$ plowup --cache=shared -a 'user:pasword' 1fichier file1.zip
$ plowup --cache=shared 1fichier file2.zip

On first command line, login stage will be performed and session (token or cookie) will be saved in ~/.config/plowshare/storage/module-name.txt. On second command line, plowup will reuse the data stored to bypass login step. You don't have to specify credentials.

Note: Only few hosters currently support cache mechanism. Have a look to Plowshare legacy modules matrix for more information.

Custom results, print upload time, link and filename in HTML format:

$ plowup 1fichier -v0 --printf '<li>%T: <a href="%u">%f</a>%n' 5MiB.bin 10MB.bin
<li>11:12:42: <a href="https://1fichier.com/?52jwehc851">5MiB.bin</a>
<li>11:12:46: <a href="https://1fichier.com/?bn1jdvtpqi">10MB.bin</a>

Plowdel

Delete a file from MegaShares (delete link required):

$ plowdel http://d01.megashares.com/?dl=6EUeDtS

Delete files (deletes are successive, not parallel):

$ plowdel http://d01.megashares.com/?dl=6EUeDtS http://depositfiles.com/rmv/1643181821669253

Delete a file from Rapidshare (account is required):

$ plowdel -a myuser:mypassword http://rapidshare.com/files/293672730/foo.rar

Plowlist

List links contained in a shared folder link and download them all:

$ plowlist http://www.mediafire.com/?qouncpzfe74s9 > links.txt
$ plowdown -m links.txt

List two shared folders (first link is processed, then the second one, this is not parallel):

$ plowlist http://www.mediafire.com/?qouncpzfe74s9 http://www.sendspace.com/folder/5njdw7

Remark: Some hosters are handling tree folders, you must specify -R/--recursive command-line switch to plowlist for enabing recursive lisiting.

List some Sendspace web folder. Render results for vBulletin BB syntax:

$ plowlist --printf '[url=%u]%f[/url]%n' http://www.sendspace.com/folder/5njdw7

List links contained in a dummy web page. Render results as HTML list:

$ plowlist --fallback --printf '<li><a href="%u">%u</a></li>%n' \
      http://en.wikipedia.org/wiki/SI_prefix

Plowprobe

Gather public information (filename, file size, file hash, ...) about a link. No captcha solving is requested.

Filter alive links in a text file:

$ plowprobe file_with_links.txt > file_with_active_links.txt

Custom results as shell format, print links information (filename and size):

$ plowprobe --printf '#%f (%s)%n%u%n'  http://myhoster.com/files/5njdw7
#foo-bar.rar (134217728)
http://myhoster.com/files/5njdw7

Custom results as JSON format, print links information (filename and size):

$ plowprobe --printf '{"url":"%U","size":%s}%n' http://myhoster.com/files/5njdw7
{"url":"http:\/\/myhoster.com\/files\/5njdw7","size":134217728}

Custom results: print primary url (if supported by hosters and implemented by module):

$ plowprobe --printf='%v%n' http://a5ts8yt25l.1fichier.com/
https://1fichier.com/?a5ts8yt25l

Use - argument to read from stdin:

$ plowlist http://pastebin.com/1d82F5sd | plowprobe - > filtered_list.txt

Configuration file

Plowshare looks for ~/.config/plowshare/plowshare.conf or /etc/plowshare.conf files. Options given at command line can be stored in the file.

Example:

###
### Plowshare configuration file
### Line syntax: token = value
###

[General]
interface = eth1
captchabhood=cbhuser:cbhpass

rapidshare/a = matt:4deadbeef
mediafire/a = "matt:4 dead beef "
freakshare/b=plowshare:xxxxx

[Plowdown]
timeout=3600
#antigate=49b1b8740e4b51cf51838975de9e1c31

[Plowup]
max-retries=2
mirrorcreator/auth-free = foo:bar
mirrorcreator/count = 5

[Plowlist]
verbose = 3

#[Plowprobe]

Notes:

• Blank lines are ignored, and whitespace before and after a token or value is ignored, although a value can contain whitespace within.
• Lines which begin with a # are considered comments and ignored.
• Double quoting value is optional.
• Valid configuration token names are long-option command-line arguments of Plowshare. Tokens are always lowercase. For modules options, tokens are prepended by module name and a slash character. For example: rapidshare/auth is equivalent to rapidshare/a (short-option are also possible here). Another example: freakshare/b is equivalent to freakshare/auth-free.
• Options in general section prevail over PlowXXX section. Options given on the command line prevail over configuration file options.

You can disable usage of Plowshare config file by providing --no-plowsharerc command-line switch. You can also specify a custom config file using --plowsharerc switch.

Use your own captcha solver

It is possible providing plowdown or plowup with --captchaprogram command-line switch followed by a path to a script or executable.

Script exit status

• 0: solving success. Captcha Word(s) must be echo'ed (on stdout).
• $ERR_NOMODULE: external solver is not able to solve requested captcha. Let plowdown continue solving it normally (will consider --captchamethod if specified).
• $ERR_FATAL: external solver failed.
• $ERR_CAPTCHA: external solver failed. Note: this exit code is eligible with retry policy (-r/--max-retries).

Examples

Understanding example:

#!/bin/bash
# $1: module name
# $2: path to image
# $3: captcha type. For example: "recaptcha", "solvemedia", "digit-4".

declare -r ERR_NOMODULE=2
declare -r ERR_CAPTCHA=7

# We only support uploadhero, otherwise tell Plowshare to solve on its own
if [ "$1" != 'uploadhero' ]; then
    exit $ERR_NOMODULE
fi

# You can print message to stderr
echo "Module name: $1" >&2
echo "Image: $2" >&2

# Use stdout to send decoding result
echo "5ed1"
exit 0

Captcha emailing example:

#!/bin/bash
#
# Sends an email with image as attachment.
# Requires heirloom-mailx and not bsd-mailx.
#
# Here is my ~/.mailrc:
#
# account gmail {
# set from="My Name <[email protected]>"
# set smtp-use-starttls
# ssl-verify=ignore
# set smtp=smtp://smtp.gmail.com:587
# set smtp-auth=login
# set [email protected]
# set smtp-auth-password="xxx"
# }

declare -r ERR_FATAL=1
declare -r MAILTO='[email protected]'

# Image file expected
if [ ! -f "$2" ]; then
    exit $ERR_FATAL
fi

BODY="Hi!

Here is a captcha to solve; it comes from $1."

mailx -A gmail -s 'Plowshare sends you an image!' \
    -a "$2" "$MAILTO" >/dev/null <<< "$BODY" || {
        echo 'mailx fatal error, abort' >&2;
        exit $ERR_FATAL;
}

echo 'Please check your email account and enter captcha solution here:' >&2
IFS= read -r
echo "$REPLY"
exit 0

Captcha FTP example:

#!/bin/bash
#
# Uploads the image to an FTP server in the LAN. If the server is not available
# (i.e. my computer is not running) or no CAPTCHA solution is entered for
# 15 minutes (i.e. I am occupied), let Plowshare try to handle the CAPTCHA.

declare -r MODULE=$1
declare -r FILE=$2
declare -r HINT=$3
declare -r DEST='192.168.1.3'
declare -r ERR_NOMODULE=2

# Prepend the used module to the image file name
curl --connect-timeout 30 -T "$FILE" --silent "ftp://$DEST/${MODULE}__${FILE##*/}" || \
    exit $ERR_NOMODULE

echo "Captcha from module '$MODULE' with hint '$HINT'" >&2
read -r -t 900 -p 'Enter code: ' RESPONSE || exit $ERR_NOMODULE
echo "$RESPONSE"

exit 0

Database using image hash as key:

#!/bin/sh
#
# Back to February 2009, Megaupload was using 4-character rotation captchas.
# For example:
# $ sqlite3 captchas.db
# sqlite> CREATE TABLE mu (md5sum text unique not null, captcha text not null);
# sqlite> INSERT INTO mu VALUES('fd3b2381269d702eccc509b8849e5b0d', 'RHD8');
# sqlite> INSERT INTO mu VALUES('04761dbbe2a45ca6720755bc324dd19c', 'EFC8');
# sqlite> .exit

if [ "$1" = megaupload ]; then
  DB="$HOME/captchas.db"
  MD5=$(md5sum -b "$1" | cut -c-32)
  if VAL=$(sqlite3 "$DB" "SELECT captcha FROM mu WHERE md5sum=\"$MD5\""); then
    echo "$VAL"
    exit 0
  fi
fi
exit 2

Plowdown advanced use

Hooks

It is possible to execute your own script before and after call to module download function. Related command-line switches are --run-before and --run-after.

Possible usage:

• (before) Check (with plowprobe) if a file has already been downloaded (same filename, same file size/hash)
• (before) Inject your own cookie
• (after) Unrar archives
• (after) Add --skip-final command-line switch and do your custom final link download

Example 1: Skip all links coming from HotFile hoster

$ cat drophf.sh
#!/bin/bash
# $1: module name
# $2: download URL
# $3: cookie (empty) file given to download module function
# You can print messages to stderr. stdout will be trashed
declare -r ERR_NOMODULE=2
if [ "$1" = 'hotfile' ]; then
    echo "===[Pre-processing script skipping $2]===" >&2
    exit $ERR_NOMODULE
fi
exit 0

$ plowdown --run-before ./drophf.sh -m list_of_links.txt

Example 2: Use wget for final download (with possible required cookie file for last download)

$ cat finalwget.sh
#!/bin/bash
# $1: module name
# $2: download URL
# $3: cookie file fulfilled by download module function
# $4: final download URL
# $5: final filename (no path: --output-directory is ignored)
# You can print messages to stderr. stdout will be trashed
echo "===[Post-processing script for $1]===" >&2
echo "Temporary cookie file: $3" >&2
wget --no-verbose --load-cookies $3 -O $5 $4

$ plowdown --skip-final --run-after ./finalwget.sh \
    http://www.mediafire.com/?k10t0egmhi23f

Example 3: Use multiple connections for final download (usually only for premium account users)

$ cat finalaria.sh
#!/bin/bash
aria2c -x2 $4 >/dev/tty

$ plowdown -a user:password --skip-final --run-after ./finalaria.sh \
    http://depositfiles.com/files/fv2u9xqya

Miscellaneous

Additional cURL settings

For all network operations, Plowshare is relying on cURL. You can tweak some advanced settings if necessary.

For example (enforce IPv6):

$ echo 'ipv6' >>~/.curlrc

Use Plowshare with a SOCKS proxy:

$ ssh -f -N -D localhost:3128 [email protected]
$ echo 'socks5=localhost:3128' >>~/.curlrc

Note: As Plowshare is dealing with verbose, be sure (if present) to have these cURL's options commented:

#verbose
#silent
#show-error

Known limitations

For historical reasons or design choices, there are several known limitations to Plowshare.

1. You cannot enter through command-line several credentials for different hosts. It's because the modules option -a, --auth, -b or --auth-free have the same switch name. But you can do it with the configuration file.
2. Same restriction for passwords (also a module option). Only one password can be defined with -p, --link-password switch name.

Implement your own modules

Plowshare exports a set of API to help text and HTML processing. It is designed to be as simple as possible to develop new modules. A module must be written in shell with portability in mind; one module matches one website.

• New module documentation
• API list

A common approach is to read existing modules source code.
