Ruby FTP sendcmd error - ruby

ftp = Net::FTP.new(IPAddress)
ftp.login(UserName, Password)
ftp.sendcmd("prompt")
ftp.sendcmd("mget filename*")
This code returns the following error.
/usr/lib/ruby/1.9.1/net/ftp.rb:261:in `getresp': 500 'PROMPT': command not understood (Net::FTPPermError)
from /usr/lib/ruby/1.9.1/net/ftp.rb:269:in `voidresp'
from /usr/lib/ruby/1.9.1/net/ftp.rb:292:in `block in voidcmd'
from /usr/lib/ruby/1.9.1/monitor.rb:190:in `mon_synchronize'
from /usr/lib/ruby/1.9.1/net/ftp.rb:290:in `voidcmd'
Why is Ruby converting my command to UPPERCASE while I am giving it in lower case.

i don't think sendcmd is used this way. Try this alternative
require 'net/ftp'
user="user"
pass="password"
server="server"
Net::FTP.open(server) do |ftp|
ftp.login(user,pass)
ftp.nlst("filename.*").each do |file|
ftp.getbinaryfile(file,file)
end
ftp.close
end

How to use Icescrum with Dashing (widget)?

I am trying to create a widget on Dashing that will extract data from Icescrum and update a specific widget.
The thing is I found info on how to program jira, so i've been trying to mess around with it to make it work with icescrum, but with no luck.
I tried this one:
require "uri"
require "net/http"
require "json"
SCHEDULER.every '2s', :first_in => 0 do |job|
uri = URI.parse("http://website.ca:8080/icescrum")
http = Net::HTTP.new(uri.host, uri.port)
req = Net::HTTP::Get.new("uri.request_uri")
req.basic_auth username, password
response = http.request(req)
issuesinProgress = JSON.parse(response.body)["total"]
send_event('synergy', value: issuesinProgress)
end
but I got this error:
scheduler caught exception:
undefined local variable or method `username' for main:Object
/home/administrator/dashboard/jobs/sample.rb:27:in `block in <top (required)>'
/var/lib/gems/1.9.1/gems/rufus-scheduler-2.0.24/lib/rufus/sc/jobs.rb:230:in `call'
/var/lib/gems/1.9.1/gems/rufus-scheduler-2.0.24/lib/rufus/sc/jobs.rb:230:in `trigger_block'

/var/lib/gems/1.9.1/gems/rufus-scheduler-2.0.24/lib/rufus/sc/scheduler.rb:430:in `call'
/var/lib/gems/1.9.1/gems/rufus-scheduler-2.0.24/lib/rufus/sc/scheduler.rb:430:in `block in trigger_job'
Your code has a line:
req.basic_auth username, password
It's expecting two variables, "username" and "password", but neither look to be defined in your code, here. If they aren't defined you'll get an error that looks an awful lot like what you're getting.
So finally I just used a cURL function to get the information. I'll leave it here if anyone else needs it. It also sends the results to an xml file (if you don't want that then just remove the last part)
.rb file:
%x{curl -v -H "Content-Type: application/xml" -X POST --data "#filename.xml" -u username:password http://website.ca:8080/icescrum/ --output result.xml}
Remember to change these dummy names with your links:
filename.xml
username
password
website.ca:8080/icescrum/
result.xml
a complete set up of the widget is also available here :

How to parse XML with Mechanize and XMLSimple in ruby?

I'm trying to fetch a remote XML file with Mechanize to get icecast status information. But I'm having problems to pass the XML file from Mechanize::File format to string or some XML format which XMLSimple can work with.
The XML document looks like that:
<icestats>
<admin>donschoe#stackoverflow.com</admin>
<!-- ... -->
</icestats>
My code looks like that right now:
require 'mechanize'
require 'xmlsimple'
server = 'example.net'
port = 8000
user = 'stackoverflow'
password = 'hackme'
agent = Mechanize.new
agent.user_agent_alias = 'Linux Firefox'
agent.add_auth("http://#{server}:#{port}/admin/status.xml", user, password)
agent.get("http://#{server}:#{port}/admin/status.xml")
xml = agent.current_page
status = XmlSimple.xml_in(xml)
puts status['admin']
This should output: donschoe#stackoverflow.com
But it throws:
/home/user/.gem/ruby/1.9.1/gems/xml-simple-1.1.2/lib/xmlsimple.rb:191:in 'xml_in': Could not parse object of type: <Mechanize::File>. (ArgumentError)
Now, I understand the XMLSimple needs a string and therefore I tried to convert the Mechanize::File format to string, replacing the second last line with:
status = XmlSimple.xml_in(xml.to_s)
But this throws an even more weird exception:
/usr/lib64/ruby/1.9.1/rexml/parsers/baseparser.rb:406:in `block in pull_event': Undefined prefix Mechanize: found (REXML::UndefinedNamespaceException)
from /usr/lib64/ruby/1.9.1/set.rb:222:in `block in each'

from /home/user/.gem/ruby/1.9.1/gems/xml-simple-1.1.2/lib/xmlsimple.rb:203:in `xml_in'
from debugging.rb:16:in `<main>'
What's wrong with my approach? When I download the XML file and use the local XML file the code above works as desired.
I'm especially looking for solutions with Mechanize rather than Nokogiri.
Try changing:
xml = agent.current_page
to:
xml = agent.current_page.body

Ruby Spreadsheet: Bad file descriptor - test.xls (Errno::EBADF)

I have problem with script that makes simple .xls file and writes data to one cell. Here is simple code:
require 'spreadsheet'

def filter
#excel = Spreadsheet::Workbook.new
#sheet = #excel.create_worksheet
#sheet[0, 0] = "test"
#excel.write 'test.xls'
end
end
f = Filter.new
f.filter
But it raises error:

because ruby-ole 1.2.11.5 doesn't support windows platform,
more detail: ruby-ole issue
you can use ruby-ole 1.2.11.4 to avoid this problem.
require 'rubygems'
gem 'ruby-ole','1.2.11.4'
require 'spreadsheet'
I've seen these before. First verify that you can write to that file's location.
My guess is either the file is already open in Excel or your antivirus is blocking the 'threat'.

Ruby Net::FTP gettextfile not able to save files locally

I am trying to retrieve files (.csv) from an ftp site and save them all locally in the same folder. My code looks like this:
#! /usr/bin/ruby
require 'logger'
require 'fileutils'
require 'net/ftp'
require 'rubygems'
require 'mysql2'
require 'roo'
require 'date'
# logging setup
log = Logger.new("/path_to_logs/ftp_log.log", 10, 1024000)
log.level = Logger::INFO
export_ftp_path = '/Receive/results/'
export_work_path ='/Users/pierce/results_exports/'
Net::FTP.open('host', 'username', 'password') do |ftp|
log.info("Logged into FTP")
ftp.passive = true
ftp.chdir("#{export_ftp_path}")
ftp.list.each do |file|
log.info("Found file #{file}")
new_file = file[56..115] #take part of the file name and remove spaces and periods
new_file = new_file.gsub(/[.]+/, "")
new_file = new_file.gsub(/\s/, "0")
ftp.gettextfile(file,"#{new_file}")
log.info("Downloaded file #{new_file}")
end
end
And here is the error I receive:
/Users/pierce/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/net/ftp.rb:560:in `initialize': No such file or directory - (Errno::ENOENT)

from /Users/pierce/.rbenv/versions/1.9.2-p290/lib/ruby/1.9.1/net/ftp.rb:116:in `open'
As suggested, here are the values I have for puts file and puts new_file.
file = -rwxr-xr-x 1 1130419 114727 9546 May 17 08:11 results_Wed. 16 May 2012.csv
new_file = results_Wed0230May02012csv
Any suggestions on what to change in gettextfile or within my script to get the files saved correctly?
You should use nlst instead of list when you just need a list of files in a directory. The output of list needs to be properly parsed otherwise.
When you request the file it has to be the original filename, including all spaces. When you save the file it can be anything you want (including spaces or not). The error was because you were requesting the wrong file. Use nlst in your case instead. It will make it much easier (no conversion or parsing needed).

Using Ruby to fuzz FTP Server

Hey, I'm new to Ruby and trying to learn by porting some progs from one language to another. Right now I'm working on an FTP fuzzer in Ruby that mirrors this perl script:
use Net::FTP;
$target = "192.168.37.128";
$buffer = "A\x20";
$buffer .= "A" x 512;
$ftp = Net::FTP->new($target, Debug => 0, Timeout => 5)
or die "Cannot connect to $host: $# \n";
$ftp->login("anonymous",'anonymous#nowhere.com')
or die "Couldn't log in: $#\n";
$ftp->list($buffer);
$ftp->quit;
This is my Ruby equivalent:
require 'net/ftp'
buffer = 'A\x20'
buffer = (buffer + ('A'*512))
ftp = Net::FTP.open('127.0.0.1','anonymous','anonymous')
ftp.login
ftp.list(buffer)
ftp.quit
When I run the program I get the following error:
C:/Ruby192/lib/ruby/1.9.1/net/ftp.rb:241:in `readline': end of file reached (EOF
Error)

from C:/Ruby192/lib/ruby/1.9.1/net/ftp.rb:682:in `list'
from ftpcrash.rb:10:in `<main>'
I've traced the issue to the ftp.list(buffer) line, but can't come up with a Ruby solution that will accomplish what $ftp->list($buffer) does in the perl one.
Suggestions?
The buffer is unnecessary. #list takes an optional argument like '*n', not a buffer, and it returns an array.
require 'net/ftp'
ftp = Net::FTP.open('ftp.gnu.org','anonymous','')
puts ftp.list
ftp.quit
Judging by net/ftp.rb source code this exception is raised when ftp library is trying to get a response from the server and response is empty.
You should wrap this command in begin/rescue/end (or just rescue) and handle the error accordingly.
Here What you want dude
#!/bin/ruby
require 'socket'
buffer = "A" * 512
host = 'xx.xx.xx.xx'
port = 21
s = TCPSocket.open(host, port)
s.recv(1024)
s.send("USER anonymous\r\n", 0)
s.recv(1024)
s.send("PASS anonymous\r\n", 0)
s.recv(1024)
s.send(buffer + "\r\n", 0)
sleep 0.3
s.close
Stay Secure ;)
