put it in one line might help, but make sure seahawk is the machine name
of master server and show by resolvable( see ping seahawk)
or try to use FQDN like "seahawk.your_domain.com", if yopu do not have
working DNS server you can put it to /etc/hosts file like following
your_ip seahawk.your_domain.com seahawk
good luck
