5933.0. "%MCC-E-PROTOCOLINUSE, when NET$MOP process is running" by UTRTSC::BEEKMAN (Ton Beekman - NL/MCS - 7838-2345) Wed Apr 06 1994 05:46

%MCC-E-PROTOCOLINUSE, when NET$MOP process is running.


Following configuration: DECmcc station with VMS V6.0 and DECnet/OSI V5.7

I'm unable to use the Ethernet Access Module if the NET$MOP process 
is running. 
If I want to access an already registered station, DECmcc will hang for a 
long time and produces the following error.

MCC> sho station w all attr

Station LOCAL_NS:.w
AT  6-APR-1994 09:54:11 All Attributes

The requested operation cannot be completed
                      MCC Routine Error = %MCC-E-PROTOCOLINUSE,  protocol is in
                                          use and not available.

                              Text File = -- Attribute Not Available
    

If the NET$MOP process is stopped then everything works well.

So, what do I have to do to run NET$MOP and DECmcc at the same time on the
same system?

5933.1The protocol is indeed "in use"AZUR::ANTEUNISLost Software Rescue TeamWed Apr 06 1994 07:069
What You are facing is that there are 2 consumers of the same protocol. 
You need to interpret the word protocol as the value found in the ethernet packet's
protocol field.

What happens is that the NET$MOP process tells the ethernet controller: "give me all
packets with protocl == nnn". Then MCC comes along, and it says the same thing. So the
Ethernet controller anwers "protocol already in use"

5933.2No can do...BIKINI::KRAUSEEuropean NewProductEngineer for MCCThu Apr 07 1994 05:254
And the bottom line is: you can't run both on the same machine. I 
believe this restriction is documented somewhere (release notes?).
