thanks for your replies to my confusion. now that the 'check message length ' button has been pointed out to me , the window's content no longer seems inappropriate-only that it appeared when i clicked the 'Submit reply' button (yes, that,s what i hit, no question, hence the reinforcement of the idea it was a warning). taken together with the nytimes thing(to which i had recently posted a link on lq), i got to realizing how little i know about how things were operated and that i'd better pay some attention. time is always an issue, and there's only so much of it for my computing knowledge(a speck in the cyber cosmos); so i take one thing at a time,usually as necessity dictates. what started out as a desire to control a telscope(12" reflector homemade; the sky on a clear frigid night from the top of a isolated mountain is heady stuff) has brought me to a fascinating otherworld of interesting people and cool devices.
so, i'll chalk this up to an inadvertancy of some sort, not an alien takeover(governmental interference remains on the suspect list) and i thank you, jeremy, for taking time to point out a simple possibility. my thanks also to Thoreau, to whom i might better have phrased the question, "what is sunprc and why is it on port 111?"
i now believe it is part of jdk which i put on here for the plugins and a robotic programming thing sun had going on a while back. feel free, however to enlighten me at any moment, on any issue, as time marches on and i have many miles to go before i sleep. thanks.
