Sto eseguendo un contenitore Ubuntu 16.04 con Proxmox 5.2-11. Dopo aver applicato l'ultimo round di patch 1 non riesco ad accedere alla console o tramite ssh.
Ho montato il container root FS sull'hypervisor e l'ho aggiunto pts/0
a /etc/security/access.conf
(eseguiamo pam_access
) e questo ha permesso l'accesso root alla console. Abbiamo root : lxc/tty0 lxc/tty1 lxc/tty2
in access.conf
cui pensavo fosse sufficiente, quindi il motivo per cui avevo bisogno pts/0
ora è sconcertante.
Ho notato che ssh non era in esecuzione, quindi ho provato a avviarlo manualmente ( /usr/sbin/sshd -DDD -f /etc/ssh/sshd_config
) e ho ricevuto questo errore:
Missing privilege separation directory: /var/run/sshd
Ho creato la directory a mano, avviato ssh
e ho potuto finalmente accedere, ma dopo un riavvio il problema persiste. La directory non viene creata. Solo i bit utili journalctl
e l'unica parte interessante riguarda qualcosa "operazione non consentita" ma nessuna ulteriore informazione.
Non ho familiarità con il 16.04, quindi mi chiedo come posso scoprire di più sul problema. Io non ho /var/log/syslog
o /var/log/messages
solo kern.log
così gentile di Lost.
