example is generated when a host on the private network accesses a DNS server on the public network
in type-A query mode. In this mode, the host queries an IPv4 address by domain name.
<Sysname> debugging alg packet
*0.418080 Sysname ALG/8/PACKETS: Receive a DNS query packet.
// The ALG module received a DNS query packet.
# Enable ALG packet debugging on the device with NBT ALG enabled. Output similar to the following
example is generated when a host on the private network pings the hostname of another host on the
public network.

Received a NBT NAME QUERY REQUEST.
// The ALG module received an NBT query request.
# Enable ALG packet debugging on the device with SQLNET ALG enabled. Output similar to the
following example is generated when an Oracle client on the public network tests the database
connection in its network configuration wizard.

•
The RTSP client is RealPlayer software on the private network.
•
The URL contains the IP address of an RTSP server and the name of the media file.
