Hello everyone,
I am trying to setup a PXE server on a computer on which I've just
installed Debian 9.2.
So I've installed tftpd-hpa, and left the configuration as it was:
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/srv/tftp"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure"
But, I can't connect to port 69, from other computers. I'm getting a timeout
This seems very strange, since I can see the tftp service in netstat:
:~$ sudo netstat -tulpn
Active Internet connections (only servers)

The firewall was left with its defaults on this computer:
:~$ sudo iptables -L -nv
Chain INPUT (policy ACCEPT 968 packets, 96829 bytes)
pkts bytes target prot opt in out source
destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source
destination
Chain OUTPUT (policy ACCEPT 525 packets, 129K bytes)
pkts bytes target prot opt in out source
destination
However, if I check the ports from other computers, it seems that nothing's
listening there:
:~$ nc -vz lab 69
lab.home.org [192.168.1.179] 69 (?) : Connection refused
:~$ nc -vz lab 22
lab.home.org [192.168.1.179] 22 (ssh) open
But, if I try to connect from localhost, I can get a test file that I've
created in /srv/tftp/:
:~$ echo "get hello.txt" | tftp 192.168.1.179
tftp> Received 7 bytes in 0.0 seconds
tftp>
Does anybody know what's happening here? What I should check?
Please help me with any suggestions or ideas you might have.
Thank you,
