ok suricata is obvious



can be done as unbound config too…



another dumb idea of mine is a smtp server u put on mx weight 100 and also listens on 53 as a rbl server…ur weight 0 smtp simply has this guy in his main.conf as smtpd restriction or something..


and so i still dunno why postfix dun have built in blackhole address.. i specify a specific email address, u send to it…ill block u…as in. ill add u to a blacklist that none of my users will ever receive mail from again…
its like when u monitor for connections at port 70 n drop their ip…
is this a antivirus?!?!?! i m so lost

  • SIZE – This parameter defines how much space you want to allocate in the RAM to store log files. The default value is 40M.
  • USE_RSYNC – If you want to synchronize the contents of RAM using rsync program, just set this parameter value as true. By default, Log2ram uses “cp” command to copy contents of tmpfs to disk.
  • MAIL – This parameter is used to notify error messages. You can also disable the error system mail if there is not enough place on RAM. To disable it, simply set its value as false.
  • ZL2R – This parameter enables zram compatibility in your system. It is disabled by default. To enable this option, check this link.

  3. he say something like 40% of concrete is pre cast now. how about use industrial waste water for casting n curing? once my man-made rock forms, the toxic shit is locked inside forever?
