Ho avuto uno script che ha funzionato per un certo numero di anni su Linux (ubuntu 14.04) che ssh è sul mio iMac.
Ho impostato coppie di chiavi pubbliche private per lo script per accedere a iMac. Ho riscontrato un problema quindi ho rigenerato le coppie di chiavi pubbliche private utilizzando ssh-keygen -t rsa -b 2048 poi ho messo la chiave pubblica in ~ / .ssh / authorized_keys ho fatto in modo che le autorizzazioni di .ssh fossero impostate su 0600
Ho fatto la generazione della chiave reciproca su ubuntu e l'imac può accedere a ubuntu ho aggiornato le porte su imac.
una trascrizione di ssh -v 192.168.1.111 (imac) da (ubuntu) segue:
