SSH into the container is exposed to the world

@wildloop

Because the Dockerfile runs EXPOSE 22 and Docker automatically modifies firewall rules, running this container means SSH gets exposed on your public IP.

The Dockerfile also enables root login over SSH (bad) and sets the root password to root (quite bad) 🤦

I recently left this running over night, and in the morning I found out that someone was mining Monero on my machine.

Is SSH really necessary? Why can't we just use docker exec instead?

Calling tesseract from ruby app gives "sh: tesseract: not found"

After using an adapted version of the docker file provided in this repo that adds my app. When i call tesseract from my ruby app i get sh: tesseract: not found. My Dockerfile looks like this and installs fine:

WORKDIR /app

ADD . /app

ENTRYPOINT ["ruby", "app.rb"]`

my app looks like this:

require 'sinatra'
require 'fileutils'
require "carrierwave"
require 'carrierwave/datamapper'
require "carrierwave/orm/activerecord"
require_relative 'models/image'
require_relative 'data_mapper_setup'

set :protection, except: [ :json_csrf ]

set :port, port
set :bind, '0.0.0.0'

CarrierWave.configure do |config|
config.root = File.dirname(FILE)
end

get '/' do
({"Hello" => "World!"}).to_json
end

post '/extractText' do
begin
path = File.dirname(FILE)
billID = params[:billID]
image = Image.new(file: params[:file])
file = File.new("#{path}#{image.file.url}")
system("tesseract #{file} --psm 6 resultsFile.txt")
results = File.read("resultsFile.txt")
rescue
status 402
return "Error reading image"
end
status 200
return resultsFile.to_json
end
`

The line where i get the error at after passing the file is system("tesseract #{file} --psm 6 resultsFile.txt")

Any help would be great

Link to test image broken in 6-test-ocr.sh

Newbie question....

Hello!
I have a virtual machine (Hyper-V) with Lubuntu installed:
(Ubuntu 21.10 "impisb" base).
I installed Docker an run scripts 1 to 6. I can do the OCR test (although I had to modify the script 6-test-ocr.sh , phototest.tif is not available anymore at the location specified in the script).
But I cannot connect to SSH / localhost at port 4022. If I understand right, it should be user root and passwort root but this connection is always refused. What could be the reason?
Kind regards,
Micha

Error: No "autobuild" file in leptonica source folder

Looks like "autobuild" file already disappeared from leptonica source, but the compile script still using it.

# ${SCRIPTS_DIR}/compile_leptonica.sh
... ...
parallel-tests: installing 'config/test-driver'
autoreconf: Leaving directory `.'
/home/scripts/compile_leptonica.sh: line 5: ./autobuild: No such file or directory
make: *** No targets specified and no makefile found.  Stop.

And check the leptonica folder:

# ls ${LEP_SRC_DIR}
CMakeLists.txt  Makefile.in  aclocal.m4    autom4te.cache  configure     lept.pc.cmake          lok.lua        make-for-local  src              version-notes.html
Doxyfile        README.html  appveyor.yml  cmake           configure.ac  lept.pc.in             m4             moller52.jpg    style-guide.txt
Makefile.am     README.md    autogen.sh    config          cppan.yml     leptonica-license.txt  make-for-auto  prog            sw.cpp

Remove the && ./autobuild command in that script should safely fix the issue.

Running update script breaks compilation

With error:

libtool: error: REVISION '00' must be a nonnegative integer
libtool: error: '4:00' is not valid version information
