Can I connect to remote DB using psql?

[mrflibble]

I've got a postgres db running on a windows mc. I've set it up to accept remote connections. Can I use psql from another machine (*nix) to connect to it?

I've tried this:

psql MYDB -U postgres -h 192.168.1.20

but I get the error

missing or erroneous pg_hba.conf file

which I don't understand.

The pg_hba.conf file is a configuration file residing on the host, isn't it? Why is the client asking for it?

I've figured it out. The message was coming from the server (so successful connection made) but the server had a mis-configured conf file.
