I have a tftpd server S running on centos 7 and managed by systemd It is not respoding to A server which is sending the tftp read request RRQ.
I do see the RRQ packets coming from A to S, but S never responds back from a different port Y to A So this part is working fine https://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol#/media/File:Tftp-rrq.svg But I do not see any attempts to even send a data packet back in my packet capture running on S So this event is not occuring, as if my tftpd server is dead. I have the firewalld turned off on S to eliminate the possibility that firewalld blocking those packets from reeaching to tftpd daemon. I also turned off selinux to eliminate any permission issue. https://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol#/media/File:Tftp-dat1-dwn.svg I do have tftpd running and managed by systemd $ systemctl status -l tftp ● tftp.service - Tftp Server Loaded: loaded (/etc/systemd/system/tftp.service; indirect; vendor preset: disabled) Active: active (running) since Wed 2018-03-28 18:57:42 UTC; 1min 44s ago Docs: man:in.tftpd Main PID: 1685 (in.tftpd) Memory: 136.0K CGroup: /system.slice/tftp.service └─1685 /usr/sbin/in.tftpd --verbose --verbosity 10 --secure /tftpboot --port-range 4069:4169 Mar 28 18:57:42 S.example.net systemd[1]: Started Tftp Server.
