Rotating log (default)

By default CHARON-VAX utilizes a so called "rotating log" mechanism. This means that a new default log file is created each time CHARON starts and can switch to another log file if the size of the log file exceeds 64Kb (this behavior can be changed with the "set session log_file_size" and "set session log_rotation_period" parameters; see more details in the "General Settings" chapter of this guide).

#set DUA container[2]="/dev/srN"
#set DUA container[3]="<file-name>.iso"

#load RQDX3 DUB address=...
