does pinging a device indicate if a firewall is present on the device?

[rookie1010]

Hello

I have got a wireless media player(Philips SLM5500), i wanted to find out if it had a built in firewall. i tried pinging it and all the packets returned.

Is the ping done at layer 2?

does a perfect response to a ping mean that a firewall is not present on the media player
is there any way to ping a device and find out which ports are blocked?

you have another post about this same issue on the front page, no need for another one. regardless...

ping uses ICMP and is located on Layer 3. A successful response means nothing, and port scans are more likely to show what services are running on a box.

if you're worried about one built into the box, look at the specs of it and its network card. they arent going to "sneak" one on.

if you're having a related issue dealing with open/closed ports, please post the root problem instead of having us assist YOUR troubleshooting.

thanks for the reply,

apologies for the incovenience i will keep all my questions in one post.

i read an article which states that the SLM5500 has a built in firewall when i called phillips they say it does

i was trying to stream pictures/videos from the nokia N95 to the SLM5500, both connected through a netgear wireless router. they are both upnp enabled.

the slm5500 can see the N95 and can pull the content while the N(5 can not see the slm5500, i was hence wondering if there was some sort of firewall blocking port 1900 for the N95, this would explain why the N95 could not see the SLM5500.

only one way to find out, get your favorite port scanner (nmap, hping) and scan the range.

thanks for the response,

i have installed nmap but when i click on it, it displays the command prompt for 1/2 second and then goes away.

should i continue on this thread or on the thread where i have posted the entire problem?

if youre using the windows version, its a command line tool *only* and youll need to run it from a command line directly, and then with the appropriate switches or arguments
