Mysql pres SSH problem

[Ing. Martin Hankovec]

Zdravim,
mam takovy problem: rozchazim na novem serveru pripojeni k mysql databazi ze vzdaleneho klienta na server pres SSH tunel. Vygeneroval jsem rsa klice, z klienta se na server muzu nalogovat (pres ssh), ale nejde mi vytvorit SSH tunel (respektive se vytvori, ale nechodi).
Tunel jsem vytvoril z klienta pomoci (adresa serveru byla nahrazena xxx):

ssh -v -fNg -L 3307:127.0.0.1:3306 replikace na xxx.xxx.xxx.xxx

coz by mi melo presmerovat port 3307 na klientu na port 3306 na serveru. Prikaz vypise:

debug1: Local forwarding listening on 0.0.0.0 port 3307.
debug1: fd 4 setting O_NONBLOCK
debug1: channel 0: new [port listener]

Pokud zkusim na klientu:
# mysql -h 127.0.0.1 -P 3307 -u ... -p
debug1: Connection to port 3307 forwarding to 127.0.0.1 port 3306 requested.
debug1: fd 5 setting O_NONBLOCK
debug1: channel 1: new [direct-tcpip]

A ceka dlouho, dlouho az spadne na timeout. Podle vypsanych zprav bych rekl, ze autentizace je OK, ale bude asi nejaky problem na serveru s MySQL. Kdyz se zkusim pripojit bez SSH klasicky na port 3306, tak vse chodi. Kdyz zkusim vytvorit tunel na port sendmailu (25) a pripojit se k nemu telnetem, tak to take chodi.
Kdyz zkusim to same na jinem serveru, tak vse chodi vcetne mysql pres SSH. Uz jsem prohledl snad vsechno a nenapada me, co jeste zkusit.

Nemate prosim nekdo nejaky napad, co jeste vyzkouset? V logu mysql ani jinde jsem nic nenasel.

Diky moc
Preji pekny den
