A company using NetBSD on their servers installed a new firewall. This
firewall blocks all identd queries (it just eats the packets). Now, when
someone tries to telnet/ftp/smtp into a NetBSD box through the firewall,
NetBSD sends out an identd query, gets no response, sends out another
packet in 5 seconds, gets no response, and proceeds to login after a 10
second (total) delay.
What should the firewall do? Is it ok to just drop the packets or should
some ICMP packet (or something) be returned? I was told that the firewall
can not be configured to do this.
Is it possible to disable the identd query in ftpd, telnetd, sendmail, and
whatever daemons use it?
