Re: tftpd does not work in QNX Neutrino 6.5.0
Thank you very much for your prompt reply.
Yes, I have disabled the iptables on my Linux PC.
On my QNX target, the /etc/services has tftp port 69 enabled:
# cat /etc/services |grep tftp
tftp 69/tcp
tftp 69/udp
The netstat shows that tftp is enabled:
# netstat -a |grep tftp
udp 0 0 *.tftp *.*
But the tcpdump on QNX target shows the error of "udp port tftp unreachable":
# tcpdump -vvv -xx -e -i fec0

Any other suggestions that I can try?
