Hi folks,

for learning purposes of PXE boot environment I started to configure TFTP server:
sudo dnf install tftp-server tftp

sudo chmod 777 /var/lib/tftpboot

sudo systemctl start tftp

sudo systemctl enable tftp

sudo firewall-cmd --zone=public --add-service=tftp --permanent

sudo firewall-cmd --reload

sudo touch /var/lib/tftpboot/file1.txt

echo "Hello File 1" | sudo tee /var/lib/tftpboot/file1.txt




Now, on the same machine I can retrieve the file:

tftp myserver.mydomain.local -m binary -c get file1.txt /dev/stdout
Hello File 1



On another machine I can connect to the tftp server but the transfer of the file fails:

tftp myserver.mydomain.local -m binary -c get file1.txt /dev/stdout
Transfer timed out.



And then 


tftp myserver.mydomain.local
tftp> mode binary
tftp> trace
Packet tracing on.
tftp> literal
Literal mode on.
tftp> status
Connected to myserver.mydomain.local.
Mode: octet Verbose: off Tracing: on Literal: on
Rexmt-interval: 5 seconds, Max-timeout: 25 seconds
tftp> verbose
Verbose mode on.
tftp> get file1.txt
getting from myserver.mydomain.local:file1.txt to file1.txt [octet]
sent RRQ <file=file1.txt, mode=octet>
sent RRQ <file=file1.txt, mode=octet>
sent RRQ <file=file1.txt, mode=octet>
sent RRQ <file=file1.txt, mode=octet>
sent RRQ <file=file1.txt, mode=octet>
Transfer timed out.


What can I do to further analyse the problem ?
