J'ai essayé de faire en sorte que rsyslog transmette par TLS, sans succès jusqu'à présent.
Il semble y avoir un problème dans ma configuration, mais je n'arrive pas à le localiser.
Voici le fichier de configuration de mon serveur :
# rsyslog v5 configuration file
# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html
#### MODULES ####
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imklog # provides kernel logging support (previously done by rklogd)

# Provides TCP syslog reception
$ModLoad imtcp

J'ai créé les certificats en suivant ce guide : http://kb.kristianreese.com/index.php?View=entry&EntryID=148
Mon environnement de test ne comporte pas de FQDN, j'ai donc laissé en blanc les champs DN et FQDN et j'ai rempli le champ IP.
