The behavior of the functions implemented in Nuklei can be altered through environment variables:

• NUKLEI_LOG_LEVEL influences how verbose Nuklei is. If undefined, Nuklei assumes NUKLEI_LOG_LEVEL=0, which disables all messages from the library. NUKLEI_LOG_LEVEL can takes values between 0 and 6, which correspond to the following log levels:

  • 0: none
  • 1: fatal
  • 2: error
  • 3: warn
  • 4: info
  • 5: log
  • 6: debug

  Defining NUKLEI_LOG_LEVEL=X will enable all messages that have a level smaller or equal to X.

  Note: NUKLEI_LOG_LEVEL=0 disables messages in the Nuklei library. Messages will still be printed when using the nuklei program.

• NUKLEI_RANDOM_SEED: if set to a value greater than zero, Nuklei will seed its random generators and the libc random generator with that value. If equal to -1, Nuklei will seed the random generators with a value based on time() and the process ID. If NUKLEI_RANDOM_SEED is not set, Nuklei seeds its own random generators with 0, and does not seed the libc generator.

If you are using the BASH shell, environment variables are defined with

export NUKLEI_VAR=value

Subsequent calls to Nuklei will see that NUKLEI_VAR is defined to value.
