(i noted that udp was the the problem since the udp network statistics showed udp ports were talking to the suns that were not booting. udp appears related to tftp). both of our machines run the tcp/ip package. one is an LX system and it is this one that causes the above mentioned problem. the other, a normal explorer it is also in the habit of talking to suns via udp, but does not seem to cause any problems. i am told that sun considers this their problem but a fix that was obtained by the sun administrator did not solve the problem. thus, what i need is a means to make the ti not respond to booting suns. manually arresting the udp processes is a viable temporary fix. a better fix would be to arrest the offensive processes at boot time, or better yet, not start the processes. certainly the best fix would be to fix the running ti software to not respond to booting suns. any ideas? second...... printer problems. how might one print from a symbolics or a unix box to a printer on a ti? how might one print from a ti to a printer on a unix box or a symbolics? in all cases the printers are postscript devices. the ti printer is as omnilaser 2115. the printers on other systems vary, but are all postscript ready. our namespace server is a symbolics. it defines three printers. one is the ti, one on a pyramid unix box, and one on a symbolics. i have figured out how to make both of our tis use the one ti printer. the symbolics can use the other two. both tis however fail in using the other printers. similarly, symbolics users can not use the 2115. this is silly. is there a known configuration that will allow for sharing this resource? it would also be nice to be able to print postscript files from other systems on the ti. any of a variety of unix utilities create postscript files. these files can be copied to the ti and examined. i have however not been able to get them to produce the proper output when printed. i either get nothing or the ascii source. is this something that is doable and if so how? any help would be much appreciated. my net address is schmidt@flash.bellcore.com Robert Schmidt
