Description Need Real Name 2001-01-12 21:43:09 UTC
xinetd cannot wait for tftpd to finish the transfer because xinetd does a
select on a wait for process tftpd but tftpd does a fork() (version 0.15
was doing an execve()) and doesn't wait for its child (which does the
transfer). An 'strace -fp `cat /var/run/xinetd.pid`' shows the bug.

/etc/xinetd.d/tftp:
# default: off
# description: The tftp server serves files using the trivial file transfer
\
#	protocol.  The tftp protocol is often used to boot diskless \
#	workstations, download configuration files to network-aware printers, \
#	and to start the installation process for some operating systems.
service tftp
{
	socket_type		= dgram
	wait			= yes
	user			= nobody
	log_on_success		+= USERID
	log_on_failure 		+= USERID
	server			= /usr/sbin/in.tftpd
	server_args		= /tftpboot
#	disable			= yes
}
