[note that at least one other fellow has suggested that i just hire somebody to maintain my connectivity.] but i've been doing this for a while, and until i was away for five days, everything had been going fine for over a month. oh:: one power-out. the UPS saved the server, but everything else needed to be reinitialized. > >=20 > > The *BASIC* tools for that start with 'traceroute'.

It's too much = of a PITA. When I quit doing my own DNS my issues revolving around that = ended.=20 i dont want to sound like a goodie two-shoes, but i've been running a web site for a builder friend hereabouts. gratis.=20 tiny business; guy and two others, and since builders are hurting, why not. everything runs off my own ./master and=20 named.conf are the only file i had to bother with. that took=20 several days to get right since i've only been on-the-net since '01. some guy in Dallas saved my ancient system from collapse in jan '08 by some voodoo. how his DNS was set up was around 2/3rds different than the nutshell setup i learned from the Cricket Liu's book. it really was a superb read. cricket thought i was being a smart alec when i said that his book read like a novel. maybe i'm geekier than i thought. =20 > I use DynDNS to run my primary domain and all the others run through GoDaddy's free DNS manager. This is because I use the primary domain's hostname as my MX record on all the others. While GD's DNS is = functional, it's also cumbersome, too cumbersome to update on a semi-regular basis. > I highly suggest that you do the same. $20/year for DynDNS' full = domain service is worth the price. ok, here's just the fax, man:: since i finished me m.a. in ethics, i have a truckload of philosophical-type mumblings continually ooozing forth. at the same time, i want to finish my key-click project in C++, and add that to my speech-computer. (i talked to whoever at the OLCP in '09 and learned that there at 100million disabled children in the world. 10m or 100million, (?), something implausible from where i am... . my typing-to-speech with keyboard click would be a win on the OLPC. but most kids can learn to press the membrane keyboard hard and most watch the screen. i keep my eyes on the keyboard.) nutshell, when that project is done, i can make use of my philosophy degree. =20 i'm to the point where letting somebody else handle the dns-and-outward side sounds better by the day. i'v got more question if you care to answer them. i've been using gkg.net for a few years--8 or 9 anyway. but if switching to=20 dyndns saves a lot of my flubs, hey. gaary >=20 > My two bits (and a nibble). > -- > Ryan --=20 Gary Kline kline@thought.org http://www.thought.org Public Service = Unix Journey Toward the Dawn, E-Book: http://www.thought.org The 8.51a release of Jottings: http://jottings.thought.org Hello.
