Tema<\/h2>\r\n

Ponekad se dogodi da mre\u017ene usluge ra\u010dunala (RDP, mre\u017eni printer, skener, …) nisu vi\u0161e dostupne nakon Windows Updatea.<\/p>\r\n

Ovaj postupak mo\u017ee pomo\u0107i i kada ESET-ovi programi javljaju poruku “ARP Cache Poisoning attack” (“Napad one\u010di\u0161\u0107enjem ARP predmemorije”).<\/p>\r\n

 <\/p>\r\n

\r\n

Uzrok<\/h2>\r\n

ESET tijekom instalacije i temeljne konfiguracije namjesti svoj firewall da preuzme postavke Windowsa. No, ponekad Windows Update promijeni postavke filtriranja mre\u017enog prometa koje onda utje\u010du i na postavke ESET-ovog program koje treba a\u017eurirati. Tako\u0111er, ESET tijekom instalacije preuzima neke postavke Windows Firewalla, pa ovisi i o toj konfiguraciji.<\/p>\r\n

 <\/p>\r\n

\r\n

Rje\u0161enje<\/h2>\r\n

Na jedan od sljede\u0107ih na\u010dina mo\u017eete svoju lokalnu mre\u017eu proglasiti sigurnom, pa se blokade ubudu\u0107e ne bi trebale odnositi na nju.<\/p>\r\n

Opisane postupke treba obaviti na ra\u010dunalu koje ima scanner ili printer koji trebaju biti dostupni (svima) u mre\u017ei ili na ra\u010dunalu kojemu putem RDP-a pristupaju korisnici s lokalne mre\u017ee.<\/p>\r\n

 <\/p>\r\n

Va\u017eno<\/strong>: prije primjene pravila iz ovog \u010dlanka provjerite \u017eelite li zaista dopustiti pristup ba\u0161 svima iz svog LAN-a; mo\u017eda se na neka ra\u010dunala treba (smije) pristup dopustiti samo odre\u0111enim ure\u0111ajima s mre\u017ee, pa ograni\u010dite sukladno popisu.<\/p>\r\n

 <\/p>\r\n

Prvi korak<\/h3>\r\n

Prvo morate dobiti podatke o svojoj mre\u017ei \u0161to je najlak\u0161e putem Powershella za Windows:<\/p>\r\n

Get-NetIPAddress | Where-Object { $_.AddressFamily -eq \"IPv4\" -and $_.PrefixOrigin -ne \"WellKnown\" } | Select-Object IPAddress, PrefixLength, InterfaceAlias<\/pre>\r\n
..ili Basha za Linux:<\/p>\r\n
ip -o -f inet addr show\u00a0<\/pre>\r\n
