Tracing Access Processes

To trace access processes, you can specify options in the traceoptions statement at the [edit access] hierarchy level. The default tracing behavior is the following:

Important events are logged in a file called accessd located in the /var/log directory.
When the file accessd reaches 128 kilobytes (KB), it is renamed accessd.0, then accessd.1 and so on, until there are 3 trace files. Then the oldest trace file (accessd2. is overwritten. For more information about how log files are created, see the JUNOS System Log Messages Reference.
Log files can be accessed only by the user who configures the tracing operation.

You cannot change the directory (/var/log) in which trace files are located. However, you can customize the other trace file settings by including the following statements at the [edit access traceoptions] hierarchy level:



[edit access]

traceoptions {


file filename {
files number;
size maximum-file-size;
world-readable | no-world-readable;
match regex;
}


flag all;
flag authentication;
flag chap;
flag configuration;
flag kernel;
flag radius;
}

These options are described in the following sections:
