DNS names managed within Chemistry IT and Physics IT

Enable DNS naming authority to IT staff as appropriate. For example, including <ad.cornell.edu>. One can look through current staff's to see which may be appropriate.

DNSdb batch

The DNSDB batch interface is great if you want to do large amounts of DNS changes and it is always needed if you are working with a IP address that isn’t yours to own ( for example, Amazon ).

The DNSDB batch language help page:

The DNSDB batch interface:

Example two sets of commands used by Michael Hint Oct. 2016, each of which can be run all at once. The first:

delcname nmr.chem.cornell.edu

delcname nmrscheduler.chem.cornell.edu

addcname nmr.chem.cornell.edu nmr-prod.us-east-1.elasticbeanstalk.com

addcname nmrscheduler.chem.cornell.edu nmr-prod.us-east-1.elasticbeanstalk.com

chgcnamettl nmr.chem.cornell.edu 300

chgcnamettl nmrscheduler.chem.cornell.edu 300

NOTE: Make sure to check at the bottom the boxes for verbose and for allow things to point to subnets we don’t own.

The second: The following commands should be run with the DNSDB Batch Processor at least 24 hours after we know everything is moved. They can be run all at once, too.

delhost nmrschedulerold.chem.cornell.edu

delcname nmrschedulertest.chem.cornell.edu
