22.8 Error Log
301
Another event is logged upon a successful connection (i.e. when the line is dialed, upon
authentication on a remote server, etc.).
5.
On-demand dialing (response to a packet sent from the local network)
[15/Mar/2008 15:53:42] Packet
TCP 192.168.1.3:8580 -> 212.20.100.40:80
initiated dialing of line "Connection"
[15/Mar/2008 15:53:53] Line "Connection" successfully connected
The first record is logged when WinRoute finds out that the route of the packet does not
exist in the routing table. The log provides:
•
description of the packet (protocol, source IP address, destination port, destina-
tion IP address, destination port),
•
name of the line to be dialed.
Another event is logged upon a successful connection (i.e. when the line is dialed, upon
authentication on a remote server, etc.).
6.
Connection error (e.g. error at the modem was detected, dial-up was disconnected, etc.)
[15/Mar/2008 15:59:08] DNS query for "www.microsoft.com"
(packet UDP 192.168.1.2:4579 -> 195.146.100.100:53)
initiated dialing of line "Connection"
[15/Mar/2008 15:59:12] Line "Connection" disconnected
The first record represents a DNS record sent from the local network, from that the line is
to be dialed (see above).
The second log item (immediately after the first one) informs that the line has been hung-
up. Unlike in case of a regular disconnection, time of connection and volume of transmit-
ted data are not provided (because the line has not been connected).
22.8 Error Log
The Error log displays information about serious errors that affect the functionality of the en-
tire firewall. WinRoute administrator should check this log regularly and fix detected problems
as soon as possible. Otherwise, users might have problems with some services or/and serious
security problems might arise.
A typical error message in the Error log could be: a problem when starting a service (usually a
collision at a particular port number), problems when writing to the disk or when initializing
anti-virus, etc.
