$openssl s_client -connect xxx.xxx.xxx.xxx:443 -ssl3 -cipher EDH-RSA-DES-CBC-SHA
短い暗号鍵を使ってるのを確認したい場合に使います。
まぁほとんどの人は使う必要がありません。
sshの接続でタイトルのエラーがでた場合の対処法
１.まず/var/log/auth.logを確認
Sep 16 17:10:10 system sshd[3194]: pam_unix(sshd:session): session opened for user xxxxxx by (uid=0)
こんなメッセージが出てたら、sshd_configのAllowUsersを編集
２.sshd_config編集
$sudo nano /etc/ssh/sshd_config
AllowUsers xxxxxxx ← xxxxxxの部分にユーザ名を半角空白区切りで入力
３.設定のリロード
$sudo /etc/init.d/ssh reload
なんだかんだでたまにやるとはまります。
