dns issues
(cont.)
• single-token hostname? I.e.
uname –n returns “jazz”?
• domain name in
/SYS/NET/RESLVCNF? I.e.
“domain external.hp.com”?
• one or more nameserver entries
in RESLVCNF?
• fully-qualified domain name has
a DNS “A” record specifying the
IP address of the local machine?
• IP address has a DNS “PTR”
record specifying the fully-
qualified domain name?
• if no to any of the above,
sendmail may hang, refuse to
start, be unable to recognize the
local host, and generally fill up
syslog with interesting msgs
