Yadda za a gyara "Babu wata hanyar da za ta ɗauki bakuncin" Kuskuren SSH a cikin Linux

SSH ita ce mafi aminci hanyar haɗi zuwa sabobin Linux daga nesa. Kuma ɗaya daga cikin kuskuren da aka saba yayin amfani da SSH shine\"ssh: haɗi zuwa tashar tashar mai karɓar tashar 22: Babu hanyar da za a bi zuwa". A wannan gajeriyar labarin, za mu nuna yadda za a magance matsala da kuma gyara wannan kuskuren.

Ga hoton kuskuren da muke magana akansa. Lura cewa tashar jiragen ruwa bazai iya zama tashar tashar jiragen ruwa ta 22 ba, ya danganta da abubuwan daidaitawar ku akan mahaɗan nesa. A matsayin ma'aunin tsaro, masu gudanar da tsarin zasu iya saita SSH don samun dama ta wata tashar daban.

Akwai dalilai daban-daban da yasa wannan kuskuren ya bayyana. Na farko shi ne al'ada cewa uwar garken nesa zai iya zama ƙasa, don haka kuna buƙatar bincika ko yana sama da aiki ta amfani da umarnin ping.
