Nem vagyok kezdo ezen a teren, de most valamit nem tudok megoldani, ezert kerem a tisztelt kozosseg segitseget.
A routeremen uzemel egy dropbear szolgaltatas, amihez egy kliensrol szeretnek csatlakozni automatizaltan, jelszo nelkul. A kliensen letrehoztam a kulcsokat (root es backupuser fiokok alatt) es a pubkey-t elhelyeztem a router authorized_keys fajljaban, aminek a tulajdonosai es a hozzaferesi beallitasai rendben vannak.
A szindroma, hogy root-tal gond nelkul tudok csatlakozni, viszont a backupuser el sem jut a hitelesitesig.
root@Floor:/etc/dropbear# logread -f

Van valakinek otlete, mit rontok el? (az adatokat nemileg modositottam)

ilyet ssh -vvv akarki@akarhol stb stb stb módszerrel érdemes nézni.
Koszi! Kliens oldali log (-v):

Kozben rajottem, hogy talan a szerveren kellene a sajat .ssh/authorized_keys-t letrehozni es tolteni a belepo user-hez? Huh... talan nem voltam eleg korultekinto. Megprobalom ezt a modszert.
Mukodik - bocs a forum-post-ert, user error.
Feltételezem, hogy jelszóval megy a belépés... :)
ahogy már előttem is írták:
kliens oldalról -v kapcsoló, abból ki kéne derülni miért nem sikerül...
szerk: lassú voltam.
