Network-Related Error Messages
This table lists common errors in network configurations that might cause the setup to fail. You might
need to ask a system administrator for help.
Error Message Description Solution
Gateway
unpingable This typically means that the gateway
or IP or netmask values were entered
incorrectly during the initial software
configuration for the search appliance. Ensure that the correct values are entered
on the configuration screens. Consult your
system administrators to verify the correct
values.
Cannot ping
the DNS, NTP,
mail, or
content
server. The message is displayed on the
configuration screen and indicates
which type of server is unpingable.
The message can apply to a DNS
server, NTP server, content server, or
mail server. You are encountering one
of these problems:
• You specified the wrong
hostname or IP address
• The server is down
• The server is protected by a
router policy or a firewall.
Ensure that the hostname or IP address is
correct. Ensure that the DNS, NTP, mail, or
content server is running and start the
server if it is not running. Ensure that the
network or router policies allow the search
appliance access to the server.
DNS:
connection
timed out The search appliance established a
connection to the DNS server, but the
connection timed out. The DNS server
is busy or network traffic is interfering
with the connection. Increase the capacity of the DNS server
and monitor network traffic to correct any
traffic problems.
Cannot
resolve server
(SMTP,
SYSLOG, NTP
servers, test
URLs) The hostname you specified is not
known to the DNS servers. Ensure that you entered the server name
correctly and correct any typographical
errors.
Unable to
contact NTP
server The search appliance cannot contact
the NTP server. Ensure that you correctly identify an NTP
server on the configuration screens and
that the NTP server is running. Review the
network configuration and any firewalls to
ensure that they do not block network
traffic to and from the search appliance.
Do not attempt to operate the search
appliance without identifying at least one
NTP server.
