This week Rich tackles SSL virtual hosts--if you think it's not possible to run them in Apache, think again.
Running Name-Based SSL Virtual Hosts in Apache

s_client - SSL/TLS client program openssl s_client [ -connect host:port ] [ -verify depth ] [ -cert filename ] [ -certform DER|PEM ] [ -key filename ] [ -keyform DER|PEM ] [ -pass arg ] [ -CApath directory ] [ -CAfile filename ] [ -reconnect ] [ -pause ] [ -showcerts ] [ -debug ] [ -msg ] [ -nbio_test ] [ -state ] [ -nbio ] [ -crlf ] [ -ign_eof ] [ -quiet ] [ -ssl2 ] [ -ssl3 ] [ -tls1 ] [ -no_ssl2 ] [ -no_ssl3 ] [ -no_tls1 ] [ -bugs ] [ -cipher cipherlist ] [ -starttls protocol ] [ -engine id ] [ -tlsextdebug ] [ -no_ticket ] [ -sess_out filename ] [ -sess_in filename ] [ -rand file(s) ] The s_client command implements a generic SSL/TLS client which connects to a remote host using SSL/TLS. It is a very useful diagnostic tool for SSL servers.
Si vous gérez votre propre serveur, vous possédez forcement une connexion SSH pour y accéder à distance. SSH est indispensable car en plus de fournir un accès en ligne de commande à votre serveur, il permet de se passer complètement de serveur FTP et de déposer vos fichiers en SFTP (SSH File Transfer Protocol). Je ne suis pas un grand guru de l'admin linux mais je me débrouille, donc si ça vous intéresse, voici un petit tuto ssh pour paramétrer convenablement votre serveur SSH et le sécuriser un minimum. Vous allez voir, ça peut aller assez vite et vous éviter bien des emmerdements.
