Hello my friends,

Today i saw a weird message in /var/log/messages into my centos 4.8 system:

Feb 16 07:06:37 localhost in.tftpd[13156]: tftpd: read(ack): No route to host
Feb 16 07:06:49 localhost in.tftpd[13176]: tftpd: read(ack): No route to host
Feb 16 07:06:57 localhost in.tftpd[13172]: tftpd: read(ack): No route to host

What could be happening here? when i make a service tftpd satus it says unrecognized service, i have a tftp service up to provisioning some ip phones...

Thanks in advance

Regards

That's because the tftp server you are using works through xinetd and not as a service of its own. Is the tftp service working for the clients? Have you tried temporarily disabling the firewall?

yes, it is working for the clients, that's why i'm courious about this messages:

The firewall of my server is off

Googling[code]localhost in.tftpd read ack No route to host[/code]it appears that the clients are not responding to the ACK from the server. It is suggested that the problem is on the client side. If things are working I'd be prone to let well enough alone, particularly as you are relaxed enough to run your server without a firewall.
