Hampir di semua pertanyaan ssh tunnel ke oracle yg gw dptin dari mbah google menanyakan masalah ssh tunnel ke oracle server yg memiliki ssh server disana

tp gw punya masalah yg agak beda

Web Server(port80) and SSH Server(port 212) and Oracle client with sqlplus (192.168.137.2)

||

||

SSH client (192.168.137.1/128.21.31.111)

||

||

Oracle Server (port 1521) (128.21.31.112)

program php gw harus mengakses oracle server
trus gw lakuin

ssh -p 212 [email]user@192.168.137.2[/email] -R 1521:128.21.31.112:1521

yg gw baca ssh tunnel ini seharusnya

every connection => (in)192.168.137.2:1521 on ssh server => (out) 128.21.31.112:1521 on ssh client

laku gw coba:

[user@192.168.137.2]$ sqlplus64 user/passwd@192.168.137.2:1521/sid

hasilnya :

SQL*Plus: Release 11.2.0.3.0 Production on Wed Jul 24 09:30:17 2013
