netstat -an | grep -i listen
From 'man netstat' "netstat -i | -I interface [-abdnt] [-f address_family] [-M core] [-N system] Show the state of all network interfaces or a single interface which have been auto-configured (interfaces statically configured into a system, but not located at boot time are not shown). An asterisk (``*'') after an interface name indicates that the interface is ``down''. If -a is also present, multicast addresses currently in use are shown for each Ethernet interface and for each IP interface address. Multicast addresses are shown on separate lines following the interface address with which they are associated. If -b is also present, show the number of bytes in and out. If -d is also present, show the number of dropped packets. If -t is also present, show the contents of watchdog timers."

what nottings said. If lsof isn't in the machine, I'd grep -w LISTEN; grep -i listen will get you stuff that's LISTENING, which is a different state than LISTEN
