Thread: consulting the question about the usage about SSH Tunnel settings

dear all

i have realized the SSH Tunnel function in the PostgreSQL.i did some work as follow:

at the server side:

1.setup and configure the openssh

2.start opensshd

3.setup and deploy PostgreSQL

 

at the client side:

1.setup openssh

2.execute command：ssh -L5555:localhost:5432 Administrator@XXX.XXX.XXX.XXX(the server IP)

3.use psql or pgAdmin to connect the server.(dont configure ssh tunnel settings of pgAdmin)

i succeed.

but i have a question:

if i configure ssh tunnel settings of pgAdmin as follows:

172.16.9.102 is the remote server ip,i connect the server failed,i get error:

 When should i  use these settings?can anyone make an example for me?
