Network ports

[oga83]

I open this thread to share about network ports on BD units.
If you have any info or idea about the ports below, please post here.

My BD-E8300 has the following opened ports :

Code: Select all

PORT      STATE SERVICE
6000/tcp  open  X11
7676/tcp  open  unknown
9090/tcp  open  zeus-admin
9900/tcp  open  unknown
52345/tcp open  unknown
55000/tcp open  unknown
55001/tcp open  unknown

I also saw ports 80,443,4443 once (after running 'Upgrade' and 'Remote Management' in Assistance menu), but t was not able to reproduce it.

* Port 6000 : [EDIT] X11 server for screen replication (smartphone to TV) ?
* Port 7676 : ???
* Port 9090 : ???
* Port 9900 : Supports HbbTV protocol, probably for multi screen (http://www.etsi.org/deliver/etsi_ts/102 ... 10101p.pdf). Don't know how to use it...
* Port 52345 : Well known for Samsung Remote
* Ports 55000 : Used for DLNA
* Ports 55001 : Used for DLNA

The followings UDP ports can also be opened (but are closed by default - don't know how to have them opened)

Code: Select all

PORT     STATE  SERVICE
16967/udp closed unknown
34953/udp closed unknown

* Port 16967 : DSG / CM
* Port 34953 : DSG / CM Data
Both of them are used for Docsis Set-top Gateway (http://www.scte.org/documents/pdf/stand ... 202010.pdf)

On my BD-E6100 I found opened ports:
21, 80, 110, 143, 443, 585, 993, 995, 3128, 7676, 8080, 55000, 55001

It's surprising ! Did you check connection with FTP, HTTP, HTTPS, POP, IMAP ?

[greenhorn]

yes, I did, but nothing really happens there. I found in the BD player settings a remote control option by samsung operator. Maybe there is a trick to do a terminal connect to one of these ports.

[greenhorn]

I also tried telnet and ssh connection to any of ports, with no success. I found when I try to do https connection on port 80 and 8080 the browser make some reconnects (3-4 times), maybe it looks for some script or information on my browser to do appropriate access.

I though ssh was not enabled on any D or E series? Wouldnt you have to try netcat?

[oga83]

Port 22 is not opened => No ssh
Ports 20, 110 and 143 are the most surprising here. They are closed on both my BD-D8900 and BD-E8300
Ports 80, 443 and 4443 are opened when you enter the "assistance menu"

did not try nc.....no linux machine around. Will check tonight. Maybe have to open the player and try serial connection. Hope we can root the player.

[chaosmaker]

What I meant was that the linux flavour used in D and E series doesnt include an ssh compatibility at all.
If you are short of a linux system why not use cygwin, there is a netcat package there.

[oga83]

Netcat is also available for Windows (without cygwin) :
