나는 달리고 있다OpenSSH_6.5UsePAM yes
내 보드 와 함께 .
UsePAM no
in 을 사용할 때 /etc/ssh/sshd_config
이전 sshd
보다 느리게 실행되는 것을 관찰했습니다 .
어떻게 이럴 수있어? 내가 이해하는 바는 pam이 없으면 sshd
pam이 있는 것보다 더 빠르게 수행되어야 한다는 것입니다.
이것은sshd_config
$ cat /etc/ssh/sshd_config

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.

# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
