cat tgtd_isns.te
module tgtd_isns 1.0;
require {
type tgtd_t;
type isns_port_t;
class tcp_socket name_connect;
}
#============= tgtd_t ==============
allow tgtd_t isns_port_t:tcp_socket name_connect;
Any other ports it should be allowed to connect to ? 45c585c5b76bdd00d11b7beaf2ef31985b548526 fixes this in git I believe this is the only port, unless the user decides to use a port that is not the default one... We only care about defaults.
