I've dealt with mdmdum files before but never ones that ended in .rpm.mdmdum. 
I went back to the same same page and tried the download again and it came
across as a regular .rpm.  It may very well have been that the .rpm.mdmdsumas
in fact a check sum type of file but I never saw it again and it didn't even
appear in FCFCs download manager.  And I wasn't smoking any cigarette type
things :-)

I'm not running any type of server but the above is interesting.

Right you are I take it the syntax would be #/sbsbinervice network stop.  Is
that correct?

Uh Oh!  My router only has the ssh port forwarded.  Come to think of it I don't
know how ftp,  hthttpnd possibly others are able to communicate as they have
not been forwarded by my router.  Is there a place to look to see if LDLDAPnd
SQSQLan be disabled?  I assume that they are not needed unless I am running
LDLDAPnd SQSQLhich I don't think I am running?

I've been to Grateful Dead concerts,  done  skydiving once and way back when
took an assembly language course on punch cards for an IBM 370.  I've hand
assembled code for a Motorola 6809 on a TRTRS0 color computer and written
programs in C.  However I'm scared to death of IPIPtablesnd fifilewalls If you
know of a site about momonmothaor dummies/(network impaired) newbies let me
know and alallthough can't prpromise'll try it I do prpromise will read it or
at least read it until I get too scared :-)

Thanks for your response to my problem.
