Hi guys.

cannot get a client to get anything from 'in.tftp' server?

Connection seems to get established, _tcpdump_ shows:
...
13:13:08.331277 IP 10.3.1.100.35176 > whale.mine.priv.tftp: TFTP, length 19, RRQ "zabbix.zip" octet
13:13:13.331324 IP 10.3.1.100.35176 > whale.mine.priv.tftp: TFTP, length 19, RRQ "zabbix.zip" octet
...
journal log for tftp.service, so on the servers, shows:
...
tftpd: read(ack): No route to host
...

any & all thoughts on how troubleshoot & fix this are much appreciated.
many thanks, L.
