新規でOpenSSH-3.2.2p1を入れたのだが、何故かパスワードの認証は駄目・・・ ＲＡＳ認証は通るのに何故でしょう？ 手順は以下 OpenSSL 0.9.6ｃを./configure make make install zlib1.1.4を./config make make install OpenSSH-3.2.2p1を./configure --with-pam make make install した。 cp contrib/redhat/sshd.init /etc/rc.d/init.d/sshd chmod +x /etc/rc.d/init.d/sshd /sbin/chkconfig --add sshd cp contrib/redhat/sshd.pam /etc/pam.d/sshd
