"Connection refused" means it was refused at the kernel level; if the
postmaster had rejected the connection the message would be different.
So you need to be looking for OS-level issues.  Given that you seem to
be running a rather hoary kernel (2.6.9 is a ways back no?), maybe an
update there is indicated.  Firewall problems are a possibility too.
