Ngokufanayo, kumele amisiwe PC kanye iseva hardware oyilawulayo.

Izinhlelo ukusebenza Telnet

Emva egijima wonke amasevisi edingekayo Telnet kungaba ngokuphepha uqale nge esakhelwe-Windows ithuluzi - umugqa wemiyalo. Walibiza ngokuthi kusukela "Qala" imenyu, noma chofoza nto ezifanele, noma ukudayela okusheshayo (cmd). Kungcono njalo ukusebenzisa umugqa wemiyalo nge amalungelo umsebenzisi "Admin" (noma amadivayisi lendawo lapho usebenza, noma isizinda). Kulokhu, ungenawo ukuba uqale kabusha uhlelo lokusebenza, uma kudingeka ephakeme.
