22.8 Error Log
275
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.
Each record in the Error log contains error code and sub-code as two numbers in parentheses
(x y) . The error code (x) may fall into one of the following categories:
• 1-999 — system resources problem (insufficient memory, memory allocation error,
etc.)
• 1000-1999 — internal errors (unable to read routing table or interface IP addresses,
etc.)
• 2000-2999 — license problems (license expired, the number of users would break
license limit, unable to find license file, etc.)
• 3000-3999 — configuration errors (unable to read configuration file, detected a loop
in the configuration of the DNS module or the Proxy server, etc.)
• 4000-4999 — network (socket) errors
• 5000-5999 — errors while starting or stopping the WinRoute Firewall Engine (prob-
lems with low-level driver, problems when initializing system libraries, services, con-
figuration databases, etc.)
• 6000-6999 — filesystem errors (cannot open /save /delete file)
• 7000-7999 — SSL errors (problems with keys and certificates, etc.)
• 8000-8099 — HTTP cache errors (errors when reading / writing cache files, not enough
space for cache, etc.)
