Ruby Checking to see if website exists -

ok checking see if server running. works long port correct. if cange port 1 know not excepted skips if routine. example below works fine. change port number 99 , skips if. think should fall else section.

url = uri.parse("http://www.google.com/") url.port = 80 req = net::http.new(url.host, url.port) res = req.request_head(url.path)  if res.code == "200"     #do else     #do else end

you should provide timeout , rescue socketerror , timeout::error:

require "net/http" def check_server(server, port)   begin     http = net::http.start(server, port, {open_timeout: 5, read_timeout: 5})     begin       response = http.head("/")       if response.code == "200"         # fine       else         # unexpected status code       end     rescue timeout::error       # timeout reading server     end   rescue timeout::error     # timeout connecting server   rescue socketerror     # unknown server   end end

if want check if server up, can simplified:

require "net/http" def up?(server, port)   http = net::http.start(server, port, {open_timeout: 5, read_timeout: 5})   response = http.head("/")   response.code == "200" rescue timeout::error, socketerror   false end

it returns true if / returns 200 status code , false otherwise, i.e. other status codes, timeouts , typical error conditions.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
