Hi, I found that i could strace an already running process with -p. So i looked for the process id of the uml and tried to strace the process id. I logged the output to file but i didn't see anything related to entropy, random or anything else. In the logs on the uml i found this: ... /var/log/syslog.0:Jun 25 05:25:38 rngd[1035]: stats: entropy added to kernel pool: 216384 /var/log/syslog.0:Jun 25 05:25:38 rngd[1035]: stats: Time spent starving for entropy: (min=4390460997; avg=4902365224.400; max=5376244640)us /var/log/syslog.0:Jun 25 06:25:39 rngd[1035]: stats: entropy added to kernel pool: 246144 /var/log/syslog.0:Jun 25 06:25:39 rngd[1035]: stats: Time spent starving for entropy: (min=4390460997; avg=4902365224.400; max=5376244640)us ... /var/log/daemon.log:Jun 25 07:25:39 rngd[1035]: stats: Time spent starving for entropy: (min=4390460997; avg=4902365224.400; max=5376244640)us /var/log/daemon.log:Jun 25 08:25:39 rngd[1035]: stats: entropy added to kernel pool: 306144 /var/log/daemon.log:Jun 25 08:25:39 rngd[1035]: stats: Time spent starving for entropy: (min=4390460997; avg=4902365224.400; max=5376244640)us /var/log/daemon.log:Jun 25 09:25:39 rngd[1035]: stats: entropy added to kernel pool: 336384 /var/log/daemon.log:Jun 25 09:25:39 rngd[1035]: stats: Time spent starving for entropy: (min=4390460997; avg=4902365224.400; max=5376244640)us ... var/log/auth.log:Jun 25 10:03:42 sshd[1640]: fatal: Couldn't obtain random bytes (error 604389476) /var/log/auth.log:Jun 25 10:04:09 sshd[1647]: fatal: Couldn't obtain random bytes (error 604389476) /var/log/auth.log:Jun 25 10:09:04 sshd[1662]: fatal: Couldn't obtain random bytes (error 604389476) /var/log/auth.log:Jun 25 10:11:10 sshd[1669]: fatal: Couldn't obtain random bytes (error 604389476) /var/log/auth.log:Jun 25 10:19:24 sshd[1712]: fatal: Couldn't obtain random bytes (error 604389476) So even with the rngd daemon running, there aren't enough random bytes to let the sshd daemon running.
