is not a problem as far as I know - my 4.39 VRPC system always shows that.

In fact I've edited the file which issues the command that causes that
response so it includes a reminder that this is normal.  The file is:

 !Boot.Resources.!Internet.!Run

and I now have the lines:

 Echo JN: !Boot.Resources.!Internet.!Run - ignore msg about invalid SWI:
 Echo                                                                       

in there just before the section which contains:

| Enable UDP checksums which are disabled by default (compatibility with
earlier stacks)

X Sysctl -w net.inet.udp.checksum=1 > null:                                 

Sysctl -w net.inet.udp.checksum=1 > null:

Sorry I can't help with the other problem.
