The Debug (debug information) log is a particular log which can be used to monitor certain kind of information — especially for problem-solving.
Too much information could be confusing and impractical if displayed at the same time. Usually, administrators only need to view the information relating to a particular service or function.
Besides, displaying too much information slows down the performance of Kerio Control. Therefore, it is strongly recommended to monitor an essential part of the information and during the shortest possible period only.
Logs maintain the information records of selected events that occurred in or detected by Kerio Control. This article serves as a reference guide to know the available options within the Debug log.
The context menu for the Debug log window includes further options for advanced settings of the log and a one-click one-time view of status information.
The following options are available only to the users with full administration rights for Kerio Control:
Format of Logged PacketsFor logging network traffic, a template is used, which defines what information will be recorded and what format will be used for the log. This makes the log more transparent and reduces the demands on disk space.
- This function enables the monitoring of IPv4 or IPv6 packets according to the user-defined log expression.
- Logging of IP traffic can be canceled by leaving or setting the Expression entry blank.
Show StatusThis function provides a single overview of status information regarding specific Kerio Control components. This information can be helpful, especially while solving problems with Kerio Technologies' technical support.
Packet Dump To File
- This function enables the monitoring of IPv4 or IPv6 packets according to the user-defined log expression and saves the Debug log to the select file.
- You can download and save the packet dump on your computer and open it through Wireshark.
If the expression is too general, the packet dump file gets large and exhausts free disk space.
The network traffic is continuously dumped, even after the administrator logs out of the administration interface.
Sometimes, for these reasons, after the recording starts, a warning notification appears in the administration interface.
MessagesThis feature allows advanced monitoring of the functioning of individual Kerio Control modules. This information would be helpful when solving issues regarding the Kerio Control components or certain network services.
WAN/Dial-Up messages Provides information about dialed lines (request dialing, auto disconnection down-counter). Kerio Control services Provides information about protocols processed by Kerio Control services (DHCP server, the DNS module, web interface, UPnP support, and IPv6 router advertisement). Decoded protocols Provides the logs of specific protocols (HTTP and DNS). Filtering Provides the logs proving information on the filtering of traffic passing through Kerio Control (antivirus control, website classification, detection and elimination of P2P networks, intrusion detection and prevention, dropped packets, etc.). Accounting Provides details about user authentication and monitoring of their activities (protocol recognition, statistics, and reporting, etc.). Miscellaneous Provides additional data (e.g., packet processing Bandwidth Limiter, switching between primary and secondary internet connection, HTTP cache, license use, update checker, dynamic DNS, the system configuration in Appliance and Box, etc.). Protocol Inspection It contains reports from individual Kerio Control's protocol inspectors (sorted by protocol). Kerio VPN Provides detailed information on traffic within Kerio VPN — VPN tunnels, VPN clients, encryptions, exchange of routing information, etc. IPSec
This contains detailed information about the IPSec traffic:
- Choose General for general information about the IPSec tunnel.
- Choose Charon output for solving problems with ciphers (the same cipher must be used on both endpoints).
- Choose L2TPD output/PPPD output for solving problems with L2TP/PPP tunnels.
