Listmates,
How do you tell ssh to log in as machine x.y.z? With bind running a single machine may be known as:
ftp.domain.com mail.domain.com machinename.domain.com www.domain.com
When using ssh outbound from that box, how do you tell it to ssh as machinename.domain.com and not mail.domain.com?
Thanks.
Would it really matter if all requests go to the same machine/(ip address)?
No, this is just another of my anal retentive moments where I can't understand why my machine wants to ssh out to the world as mail.3111skyline.com. It's another of my inquisitively stupid "Why?" questions. I mean, what logic on the box looks to bind dns and says, "I want to be known as mail today? Hell, why not nemesis.3111skyline.com, it real name? (Ur, Umm, the name of the box is probably at fault) I should have called the son-of-a-bitch accommodating.3111skyline.com and I wouldn't have to put up with this stuff.
I know it doesn't matter, but why?
Yes... long time sysadmins know to name all machines using "meaningless" names (such as, at man universities, a scheme such asnames of instruments, which may all be related to a "master" machine named "orchestra"... or in commercial environments, letters coding for function and site, followed by a number. Example: whpcs023 = Warren Technical Center, High Performance Computing Group, server #23, or pcad0257 is Pontiac design center, CAD workstation #257)... and then make more meaningful names (such as www, smpd or pop) just aliases of the neutral names in the DNS servers. Sounds complicated, but it's actually easier, especially when migrating, say, an old mail server to a new mail server. Once everything is ready, the DNS entries for the alternate names are entered, and then the new DNS map is "pushed" (forced distribution over the network). Changeover is almost instantaneous -- even if the new mail server is physically located at a distance from the old one (preventing the old "swap network cables" trick) Once in the habit of ALWAYS naming machines with "neutral" names first, and making symbolic names only by means of aliasing, you're soon in the habit of ALWAYS keeping your alias maps up to date regarding these important machines which require these sorts of names. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
