The commands to issue to update your 1.5j server's LINKSWT FILE are:
 
TELL LISTSERV AT CEARN GET LINKSWT FILE
 
RECEIVE it, and insert the following file on record 1:
 
PUTALL LINKSWT FILE CONTROL NODIST PW=xxxxxxx
 
Don't forget the NODIST or you'll end up inundated with angry mail from the
other servers :-)
