ssh-add -D
První poznámka na server se hlásíte přímo jako root, je to OK a server to umožňuje (fuj :) ).Pokud tam má rootovská práva jediný člověk nebo je hlavní správce a nepotřebuje evidovat, že to byl právě on, kdo se na roota přihlásil, pak na tom není nic špatného.
Nepátrejte po důvoduTo není moc dobrá rada…

Bo diskuzi sleduji, tak mně nenapadlo nic jiného než toto…jeste bych doplnil:
"zkopiroval jsem spravny klic spravne?" - zazil jsem pouziti more id_dsa.pub a zkopirovani vypisu - klic pak nebyl jako jeden radek, ale na nekolika radcich...
"mam prava na homedir max 755?" - minimalne aix a fedora pozaduje mit pravo zapisu pouze pro usera
