Why is port 1033 open?

[jeb1138]

When I a port scan on myself using Network Utility port 1033 is open. Can anybody tell me what this might be? Does everybody else have this port open? I tried to search for info on port 1033 on the internet and come up with a bunch of information about some netspy trojan, but it sounds like something that's only for windows boxes.
Can anybody give me a little direction?

First off, that's the netinfod daemon; if you have a port you're curious about, use lsof:

sudo lsof -i :1033

(or replace 1033 with a different port). If you look at netstat:

netstat -an |grep 1033
tcp        0      0  127.0.0.1.1033         127.0.0.1.872          ESTABLISHED
tcp        0      0  127.0.0.1.872          127.0.0.1.1033         ESTABLISHED
tcp        0     60  127.0.0.1.1033         127.0.0.1.806          ESTABLISHED
tcp        0      0  127.0.0.1.806          127.0.0.1.1033         ESTABLISHED
tcp        0      0  127.0.0.1.1033         *.*                    LISTEN
udp        0      0  127.0.0.1.1033         *.*

you'll see that, fortunately, it's bound to only localhost (127.0.0.1), so other machines on the network can't hit it. If it looks like (for example) ssh's listen:

tcp        0      0  *.22                   *.*                    LISTEN

(*.22, so all network interfaces, port 22) then it could be a bad thing, since it'd be visible to other machines.
