tak s tim experimentuji, pro inetd procesy to funguje dle ocekavani (zkousel 
jsem in.telnetd), ale pro sendmail nejak ne.

do /etc/hosts.deny jsem dal zkusebne i adresu 212.71.138.15, ze ktere jsem 
zkousel posilam maily, ktere mely byt odmitnuty:

sendmail : UNKNOWN , 212.71.138.15 : twist /bin/echo "550 5.0.0 Access 
denied (you need correct reverse-DNS entry)"


a dopadlo to spatne:

Jan 22 18:52:59 linux sm-mta[29463]: twist snail.infocity.cz to /bin/echo 
"550 5
.0.0 Access denied (you need correct reverse-DNS entry)"
Jan 22 18:52:59 linux sm-mta[29463]: warning: /etc/hosts.deny, line 16: 
twist_op
tion: dup: Bad file descriptor

asi by to chtelo echo nekam jinam nez na stdout, ale kam ? Dle manualu by to 
melo byt takto spravne:

       twist shell_command
              Replace  the  current process by an instance of the
              specified  shell  command,  after  performing   the
              %<letter>     expansions     described    in    the
              hosts_access(5) manual  page.   Stdin,  stdout  and
              stderr  are  connected  to the client process. This
              option must appear at the end of a rule.


nevedel byste jeste co s tim ?
