Is there a better way to perform multiple substitutions to a string
than this?
string = ‘/…/…/…//…////…/…/etc/passwd’
while string.gsub!(/..//,’’)
end
it’s working as is, but seems odd to me to have an empty loop… I’m
just playing with the TCPServer class…
#!/usr/bin/ruby
require ‘socket’
port = 80
listen = ‘0.0.0.0’
header = “HTTP/1.1 200/OK\r\nContent-type: text/html\r\n\r\n”
httpd = TCPServer.new(listen, port)
while session = httpd.accept
request = session.gets
address = session.addr[3]
puts “#{address} #{request}”
askfile = request.scan(/GET (.*) HTTP/).to_s
while askfile.gsub!(/…//,’’)
end
reqfile = ‘/var/www’ + askfile
reqfile += ‘index.html’ if reqfile == ‘/var/www/’
if File.exists?(reqfile)
file = File.new(reqfile, ‘r’)
output = file.readlines
file.close
else
output = ‘Not Found’
output += “
Unfortunately, “#{askfile}” does not exist on
this server…
”output += ‘
perhaps you need more fortune:
’output += “
#{/usr/games/fortune}
”
output += ‘’
end
session.print header
session.print output
session.close
end
