Error during command authentication.

Error - unable to initiate communication with LISTSERV (errno=10061, phase=CONNECT, target=127.0.0.1:2306). The server is probably not started. LISTSERV - MACSCRPT Archives - LISTSERV.DARTMOUTH.EDU

Years ago I saw some file with commands in it that all began with a period.

Does anyone know what that was? I've been googling tcl/tk, tex, 
pashua, and can't seem to find any clues.

Who's got a good memory? My brain hurts. lol
