tftpd does not work in QNX Neutrino 6.5.0   
Hi QNX Support,

I am using QNX Neutrino 6.5.0, and the tftpd does not work.
I have inetd running on my Neutrino 6.5.0 target, and the /etc/inetd.conf has following tftp setting:

# ps -ef |grep inetd
    0     344112          1  - Jan01 ?        00:00:00 inetd /etc/inetd.conf

# cat /etc/inetd.conf |grep tftp 
#tftp   dgram udp       wait    root    /usr/sbin/tftpd in.tftpd
tftp   dgram udp   wait    root    /usr/sbin/tftpd  tftpd -s /tftoboot

Since the tftp daemon in Neutrino 6.5.0 is "tftpd" (not in.tftpd), so I replace the "in.tftp" with "tftpd" in "/etc/
inetd.conf".

On my Neutrino 6.5.0 target, I have following files under /tftpboot:
# ls /tftpboot/
SDMA_MUTEX     inetd.pid      sshd.pid       test.txt

When I try to tftp download the "test.txt" file from my Neutrino 6.5.0 target to my Linux PC, I got the tftp timeout:

Linux PC$ tftp -v 172.17.16.1
Connected to 172.17.16.1 (172.17.16.1), port 69

Any suggestions?

If you work from Linux machine, try to kill iptables.

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

Try to invoke this commands from Qnx machine. 


tftp localhost
tftp> get test.txt
tftp> quit 

All it normal??????

And ......... your computers in the LAN?????? Or you try to connect to Qnx machine over Internet?????????

Your IP  = 172.17.16.1. You work over NAT????????

Re: tftpd does not work in QNX Neutrino 6.5.0   
The following tftp command on my QNX target also fails:

# tftp localhost
tftp> get test.txt
Transfer timed out.

My Linux PC (IP=172.17.1.1) connects directly to my QNX target (IP=172.17.16.1), they are not on the real network.
I was able to ping QNX target from my Linux PC, and ssh login to QNX target from my Linux PC.
I was also able to tftp download a file from Linux PC to QNX target, but not the other way around.
So it seems like only the tftp client works on my QNX target, but not the tftpd server.

Try to start tftpd daemon by hand (therefore you must comment string in the inetd.conf which start tftpd).

Re: tftpd does not work in QNX Neutrino 6.5.0   
By the way , you can find tftpd sources and then find string with error you have. This solve all your problems))))

Try to remove "-s" option. Your string in inetd.conf must be as:

 tftp   dgram udp   wait    root    /usr/sbin/tftpd  tftpd /tftoboot

Typo:

tftp   dgram udp   wait    root    /usr/sbin/tftpd  tftpd /tftpboot

Re: tftpd does not work in QNX Neutrino 6.5.0   
Hi Oleg, 

Yes, you are correct. 
After taking out the '-s' option in /etc/inetd.conf, the tftpd on my QNX target works fine now.

tftp   dgram udp   wait    root    /usr/sbin/tftpd  tftpd /tftpboot

Thank you very much for all you help and great support.
You may close this support ticket now.

Thank you and Best Regards,
Jane
