3716.0. "Can't register a Bridge" by ZUR01::FRICKER () Thu Sep 10 1992 14:55

env:

VAX 4000-300
VMS 5.5-1
Mem 64KB

The installation of the MCCBMS012, ELMSAM012 and ELMSFM012 finished successfully
without any error.

I can create a DOMAIN, I can register a NODE4
but I can't register a BRIDGE. The window crash with following Error:



$ mana/enter

    Are you using DNS or the local MIR as your namespace?
3716.2Check you PrivilagesGWTEAL::WOESTEMEYERWhy??...Why not!!!Thu Sep 10 1992 17:489
    Well,
    
    I have seen similar crashes, it happens every time you try to access
    the RBMS protocol with out having the proper privilages enabled. LOG_IO
    and PHY_IO are required to use the Bridge AM.  It is odd that the
    Accvio is not trap to a correct error message, but then I'm just a
    support person and user.

    Yes, please check your privileges and see if this problem still occurs
    if you turn on LOG_IO and PHY_IO.  I'm pretty sure we have an existing
    QAR about ACCVIOs without privileges (yes, it used to give an error
    message about insufficient privilege).

    [You forgot your smiley!]  It confused me the first time I saw it
    happen too, and I'm an engineer. :-)

    I'll follow up on this and make sure this QAR gets addressed.
3716.4All Priv. and local MIRZUR01::FRICKERMon Sep 14 1992 07:446
    
    
    we use local MIR. I use the  "SYSTEM" acccount and have all
    Privileges enabled.

3716.5Request for more infoQUIVER::HAROKOPUSMon Sep 14 1992 14:1615
    Hi Kurt,
    
    Please post the results of the following commands:
    
    mcc>show mcc 0 bridge_am all char
    mcc>show mcc 0 bridge_am all status
    
    and with the bridge you are trying to register:
    
    mcc>test bridge <addr>
    mcc>show bridge <addr> all id
    
    Thanks,
    
    Bob

    >>> I had not full priv.(only TMPMBX, NETMBX) , because I started the 
    FCL via "File-view". But the window shouldn't crash, should it?
    With all privileges enabled I can register all bridge's.
    
    Thank's

3716.7Problem has been QARedQUIVER::HAROKOPUSWed Sep 16 1992 14:3713
Hi Kurt,

As Ed mentioned in .4  not having log_io and phy_io privs. may cause mcc to
crash.   It used to print an error message saying insufficient privs.
or something like that.  

The folks that did the Ethernet Access routines know about this problem
and it has been QARed.

Just to confirm.  You are able to register bridges and use the bridge AM
as long as your privs are set?

3716.8with privs I can use the bridge AMZUR01::FRICKERThu Sep 17 1992 07:0710

Yes, with all privs enabled I can register bridges and use the bridge AM

--> Yes, with all privs enabled I can register bridges and use the bridge AM

    You don't need all privileges, only LOG_IO and PHY_IO.  It's probably a
    better idea to enable only the privileges you actually need.
