문제: ssh 접속 안되는
error: grantpt: 사용 권한이 거부됨 error: session_pty_req: session 0 alloc failed
해결방안: http://www.sunmanagers.org/pipermail/summaries/2005-April/006356.html This was caused by my finish script removing the setuid bit from /usr/lib/pt_chmod. Once I added the setuid bit, non root users can login.
