I have just upgraded to the newest distro v14 and purchased End Point Manager to auto provision my yealink t46g phones. It appears their is no port 69 listening for tftp. The firewall is turned on but I have tftp set for local and internet and have tried even adding a custom port opening in the firewall so I believe it is a problem with the service itself not listening.
tftp server works as expected in Distro 14. Make sure it’s enabled in System Admin, Provisioning protocols.
Maybe I have the same problem, I upgraded to 14 and now tftp provisioning isn’t working anymore.
I tried to dig a little deeper but don’t now what to do now.
Configuration is as follows: /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -vvv -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
firewall doesn’t seem to be the problem, I disables it completely and had the same results.
when I try tftp freepbxip -c get aastra.cfg on the freepbxhost it downloads the file without error.
journalctl -u xinetd -b says Aug 10 18:44:58 myfreepbxdnsname in.tftpd[26554]: RRQ from <localaddress> filename aastra.cfg one time
If I try tftp freepbxip get aastra.cfg on my windowsmachine I get connection failed (in german it is “Verbindungsanforderung fehlgeschlagen”, don’t know the exact original translation for that).
Journalctl -u xinetd -b says exact the same as for the local freepbx but eight times.
tcpdump says (.110 is freepbx, .124 the windows client, netmask is /16, so that isn’t the problem, I can ping each other host just fine):

The problems weren’t there before the upgrade to SNG7.
So, any idea what could be wrong here?
Thanks
It actually is a big. The person that responded is mistaken. I spoke with a guru on the forums and he told me it was a bug and that tftp service is disabled at install of the distro.
Edit the etc/xinetd.d/tftp file. Your looking for "disable = yes"
Change it to “disable = no” and restart the service
Service xinetd restart
TFTP for security reason is disabled by default. You can enable it in Sysadmin module.
