Nginenkinga yokuxhuma enkonzweni ekude. Ngingayisusa kanjani inkinga yenethiwekhi?
Kunezinyathelo ezimbalwa ezingasiza ekutholeni umthombo wezinkinga. Okokuqala kudingeka siqiniseke ukuthi ikheli elikude lixazululwe kahle - singasebenzisa imiyalo efana nslookup & dig ukuxazulula igama lomgcini ekhelini le-IP. Uma ingaxazululwa, kudingeka sihlole ukuthi isevisi ekude ingafinyeleleka - singasebenzisa amathuluzi afana ne-ping, i-traceroute, nokunye okuhlobene nokuhlola ukuthi ithrafikhi yenethiwekhi iqondiswa ngendlela efanele. Uma ingafinyeleleki, kudingeka sihlole ukuthi ukuqondisa kuhleleke kahle yini nokuthi ayikho yini i-firewall evimbela ithrafikhi ephakathi. Uma isevisi ekude ifinyeleleka, khona-ke sidinga ukuhlola ukuthi singakwazi yini ukufinyelela echwebeni elithile lapho isevisi ilalela khona - lokhu kuvame ukwenziwa ngemiyalo efana ne-telnet, nc ne-nmap. Uma itheku lingatholakali, kuvame ukwenzeka lapho i-firewall ivimbela ithrafikhi evela kumanethiwekhi angaphandle noma ithrafikhi emachwebeni angajwayelekile.
