Port number Info

[s sl]

Hi

We are implementating firewall rules on our servers. For this want to have information about follwoing :

1) We have HP UX 10.2 severs where DCE is runnign our clients are using Win NT and access tha pplication by using PC-DCE which does dce_login , etal.
What is the port numbers on Unix servers that get assigned / invoked on Unix servers for PC-DCE ( product from Entegrity)

2) Also sometimes we invoke 'cdsbroswer' on HP Unix machines where the seesion is thrown to Win NT machine. In this case the communication is done with what port on Unix machine.

Hi sl,

According to the IANA docs:

http://www.iana.org/assignments/port-numbers

DCE endpoint resolution uses 135/tcp & 135/udp

As to cdsbrowser, unless you have a special http.conf file specifying a unique port, http traffic is on port 80 by default.

HTH,
Jeff

All communications to dce is done via 135 port. Dced listens at this port and maintains an endpoint mapper which is used by the Security server and cds advertiser.

The same 135. May be little more details can find a solution to your problem

Hi,


DCE end points use port 135 tcp/udp

whereas http uses port 80 by default
