Pentru cei care nu \u015ftiu, leg\u0103tura \u00eentre dou\u0103 calculatoare care se afl\u0103 la o distan\u0163a a\u015fa mare nu se poate face printr-un singur ISP (Internet service provider). Adic\u0103, dac\u0103 RDS-ul garanteaz\u0103 un minimum de \u00a02 mbps la upload, transferul cu serverul din Rusia se poate face la o vitez\u0103 mult mai mic\u0103, din cauza intermediarelor care trec, adesea, prin alte ISP-uri.<\/p>\n<h3>De ce nu sunt relevante testele de vitez\u0103 gen speedtest.net sau speedtest.nl<\/h3>\n<p>Cei de la RDS au prostul obicei de a face teste de vitez\u0103 folosind unul dintre aceste site-uri &#8222;profesioniste&#8221;. Pentru client nu este tocmai relevant, mai ales dac\u0103 d\u00e2nsul dore\u015fte ca serverele sale s\u0103 comunice cu un anumit server dintr-o anumit\u0103 \u0163ar\u0103. Unul dintre motive ar fi c\u0103 difer\u0103 ISP-urile \u015fi ruta pe care este aruncat IP-ul. De exemplu, prin UPC, conexiunea cu Rusia se poate face prin Kiev \u015fi Moscova, iar prin RDS, conexiunea se face prin Chi\u015fin\u0103u, Done\u0163k, Sankt Petesburg, Moscova. Al doilea motiv ar fi c\u0103 ISP-urile din speedtest.nl sau speedtest.net nu coincid cu cele cu care ar trebui s\u0103 comunice serverul clientului, implicit cu cele pe care se afl\u0103 serverul dedicat. Iar\u0103\u015fi va fi o alt\u0103 rut\u0103, iar testele devin irelevante.<\/p>\n<h3>Server de FTP: Filezilla vs IIS<\/h3>\n<p>Recomand \u00een special filezilla ca server de FTP. Instalarea se face pe un program host, de preferat s\u0103 fie serverul dedicat. Se creeaz\u0103 un cont \u015fi o parol\u0103 \u015fi se d\u0103 un folder pe o parti\u0163ie, la care utilizatorul s\u0103 poat\u0103 crea, \u015fterge \u015fi muta fi\u015fiere. Pentru c\u0103 intermediarele te arunc\u0103 adesea pe alte rute c\u00e2nd se stabile\u015fte conexiunea \u00eentre cele dou\u0103 calculatoare, viteza poate fi limitat\u0103 la per conec\u0163ie. O instan\u0163\u0103 de filezilla permite 2 conexiuni simultane, de aceea se pot deschide mai multe instan\u0163e pentru a vedea, exact, dac\u0103 ISP-ul client sau serverul au limit\u0103ri de l\u0103\u0163ime a benzii.<\/p>\n<h3>PCATTCP &#8211; \u00a0testare l\u0103\u0163imii de band\u0103 folosind o comand\u0103 DOS<\/h3>\n<p>PCATTCP este un progr\u0103mel care se descarc\u0103 \u015fi se pune direct pe ambele calculatoare. Este bine s\u0103 fie a\u015fezat direct \u00een r\u0103d\u0103cina unei parti\u0163ii pentru a fi accesat mai u\u015for din linia de comand\u0103. Astfel, PCATTCP poate face un test de upload, a\u015fa c\u0103 unul dintre calculatoare trebuie setat s\u0103 trimit\u0103, iar cel\u0103lalt s\u0103 primeasc\u0103:<\/p>\n<p>comanda pentru setarea calculatorului care va primi datele:<\/p>\n<blockquote><p>C:&gt; <strong>pcattcp -r<\/strong><\/p><\/blockquote>\n<p>comanda pentru setarea calculatorului care va trimite datele:<\/p>\n<blockquote><p>C:&gt; <strong>pcattcp -t [ip_calculator_care_primeste]<\/strong><\/p><\/blockquote>\n<p>Dup\u0103 executarea instruc\u0163iunii de trimitere, programul va afi\u015fa o statistic\u0103 precis\u0103, bazat\u0103 pe limita de conec\u0163ie a unuia dintre ISP-urile intermediare.<\/p>\n<p>sursa foto: <a href=\"http:\/\/www.cyberie.qc.ca\" target=\"_blank\">www.cyberie.qc.ca<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cazuri concrete: s\u0103 zicem c\u0103 cineva se hot\u0103r\u0103\u015fte s\u0103 cumpere un server dedicat \u00een Rusia, pentru a g\u0103zdui un site, \u015fi ar vrea s\u0103 vad\u0103 cu ce vitez\u0103 maxim\u0103 se poate desc\u0103rca o pagin\u0103 sau un fi\u015fier.
