Thread: cannot connect to db from remote machine

cannot connect to db from remote machine

Hello all,
 
I have a problem connecting to the postgres database from a remote machine. I wonder if I have missed something. The java client which uses jdbc times out when connecting to the remote db. The database is running on a redhat 9 linux machine and I connect from eclipse on a windows machine. 
I changed a line in postgresql.conf to:
 
  tcpip_socket = true
and in pg_hba.conf I added a line 
 
  host    all         all         192.168.1.102     255.255.255.0     trust
where 192.168.1.102 is my windows machine. The linux machine is ...103.
I restarted the postmaster, but I cannot connect. Any ideas?
 
Regards,
 
Rein

on the running machine

try netstat -nlp | grep 5432

if that shows the connection as a tcp/ip

then try telnet <machine> 5432

I think your netmask should be 255.255.255.255.

Yes, the subnet mask needs to be 255.255.255.255 and not 255.255.255.0.
thanks,
