hpa-tftp with xinetd

Good day,

Just a quick question- could someone please confirm that this is the correct
xinetd configuration (or not) for hpa-tftp?

We've noticed that, when under moderate load hpa-tftpd resides in memory,
even after there are no connections or even if xinetd is shut down. Under
light load the server goes away after each connection, as desired.

Thanks in advance!

service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/hpa-tftpd
server_args = -s /tftpboot
disable = no
}

don't know too much about xinetd, but seems correct.

tftp-hpa (in recent versions) uses the short daemon mode. So the server
remains for some minutes (default: 15 minutes) while no
tftp request arrives. Try '-t 30' and the server process will exit
after 30 seconds.

Maybe you also have some hanging tftp connections, and you see some
leftover connections that try to deliver the next packet. These should
quit after the tftp timeout, and usually they'll do. These only
handle this specific transfer, so there won't be any interaction with
different tftp transfers.

Regards,

Josef

Good day,

Thanks for your reply. I didn't see this option in the documentation, but,
it seems to be behaving as expected now. =)
