Got reports that users are unable to send mail to usda.gov sites using our
campus SMTP server (where we have usda.gov sites on campus.)
The users have said they were able to send using other servers like Google
and Microsoft.
When I look at my system, its unable to resolve the domain name. Doing a
trace, yields:
dig +trace usda.gov
; <<>> DiG 9.9.4 <<>> +trace usda.gov

/usr/local/bin/dig: couldn't get address for 'ns1.usda.gov': no more
Though it did work from the first place I had tried it....my FreeBSD
workstation, but it also fails this way on other servers around campus and
other workstations in the same subnet as my FreeBSD workstation. I do have a
ports install of 9.9.4 on here that I've been playing with (though my
resolv.conf doesn't list it first.)
Okay its some kind of fluke with this particular FreeBSD system, it doesn't
work on my home FreeBSD systems or the FreeBSD server in our datacenter or
the USDA lab here.
Would this be an error of no glue for ns1.usda.gov/ns2.usda.gov?
