close open ports
 

Hi @ll,
i got a N800 and its pretty cool...
Whatfor are the open ports 53 and 9000 ?
Do i need them ?
And HOWTO close them ?
THX

I believe 9000 is X/VNC and 53 is DNS/Bind. You don't have to worry about too much about closing them, in all honesty. This isn't Windows.

Hmmm....,found from the Internet Assigned Numbers Authority database; port 53 tcp and udp Domain Name Server.Do i need it? port 9000 seems to be a cslistener.
I am not shure what these things are about, but howto close them?
Thx again

I would take zerojay's advice and forget about it (but that's me). If you mess with access to your Domain Name Server, you will lose the ability to connect to the internet. Also, there are references in this forum to port 9000 being used by media players/servers.

i cant see why i should run a server...ok maybe realplayer needs it, but port 53 ?
a dns SEVER just for surfing is funny---not needed

Re: close open ports
 

A lot of linux machines have a local copy of dnsmasq running for faster/cached DNS resolving.

Again, you're better off just leaving it as is.

Yep, leave it, this is "linux land", not "windows world". You can set aside your paranoia and just enjoy your new gadget. ;)

okay.. but we shouldn't get too complacent, either :) Linux has flaws, too.

it's still good practice to ensure any ports that you don't need open are closed. Why port 53 is open, I don't know. I don't see why the n800 needs to run a DNS *server*?

Because I know you guys would never connect to an untrusted network you should be safe... port 9000 I guessing is used for UPnP

Re: close open ports
 

This was already answered in this thread. The N800 is running dnsmasq to do its DNS queries and cache the results. If you open up an xterm and do an nslookup, you will see that it is configured to resolv DNS names from localhost...
