vm debian + eibd + linknx + knxweb : Error in config: MysqlPersistentStorage

[chitloft]

bonsoir,
je re sèche sur ma vm debian dédiée linknx.
voici mon nouveau message

srv-domotique:~# linknx -c/var/www/knxweb/linknx.xml
2010-11-01 20:19:02 [ INFO] XmlInetServer: Starting on port 1028
2010-11-01 20:22:11 [ERROR] main: Error in config:
MysqlPersistentStorage: error connecting to 'knx' on host
'192.168.0.17' with user 'knx', error was 'Can't connect to MySQL
server on '192.168.0.17' (110)'

Error in config: Connection timed out


Mon fichier de config :
<smsgateway />
<knxconnection url="ip:192.168.0.17" />
<xmlserver type="inet" port="1028" />
<exceptiondays />
<persistence type="mysql" host="192.168.0.17" user="knx" pass="xxxxx"
db="knx" table="persist" logtable="log" />

Eibd tourne.
dans /etc/mysql/my.cnf ; j'ai bien bind-address = 192.168.0.17

etc/network/interfaces controlé:
address 192.168.0.17
netmask 255.255.255.0
gateway 192.168.0.254

Quelque idée ?
Merci
Arnaud
