j'ai un problème avec ma connection via un programme en c à mon serveur dédié ovh !

Code :

mysql_real_connect(mysqlconnexion,hostname,user,password,"client",port,NULL,0)

quand je teste mon programme en local tous marche.

voici mon fichier my.cnf

je ne comprends pas pourquoi il ne veut pas se connecter!

[Bktero]

La vérification du fichier de configuration sera sûrement plus efficace si faite par les gens du forum mysql.

Tu arrives à te connecter à ton serveur avec autre chose que ton application en C (un outil de gestion de BDD par exemple) ?

[matafan]

Tu as l'option "skip-networking", qui signifie que tu ne peux te connecter à ton serveur qu'en local (avec un socket unix).

[Bousk]

Il me semble effectivement qu'OVH n'autorise pas les connexion MySQL distantes (voir selon l'offre, ou toutes les offres je ne sais plus).
