I have xinet tftp running on centos 5.1 It seems to be running on the local network eht0 fine. My box has 2 nics. however when I connect to eth1 for tftp I get: in.tftpd[5084]: tftpd: read(ack): Connection refused How can I get tftp working on BOTH eth0 and eth1 for my phone config files. man page for in.tftpd says it automatically runs for all local networks on port 69. Is eth1 not a local network? How do I get tftp to response on eth1? Thanks, Jerry

Xinetd may have bound the service to a particular IP address. Look at your Xinetd.d config. ________________________________ From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Jerry Geis Sent: Monday, April 28, 2008 12:12 PM To: asterisk-users at lists.digium.com Subject: Re: [asterisk-users] tftp issue On Mon, Apr 28, 2008 at 11:07 AM, Jerry Geis <geisj at pagestation.com <http://lists.digium.com/mailman/listinfo/asterisk-users> > wrote: > I have xinet tftp running on centos 5.1 > > It seems to be running on the local network eht0 fine.

The netstat show 0.0.0.0
netstat -anp | grep :69

service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -v -v -v -v -s /tftpboot

}
I dont see any specific binding.
I have not been able to find a way to get tftp to work on both eth0 and
eth1.
Thanks,

Looks good to me... Also Both networks start at boot.

Try this: after doing the service iptables stop do the following and see if there are any rules left: iptables -L iptables -t nat -L iptables -t mangle -L if there are any rules at all listed, replace the -L with -F and re-run the commands. -Brent

How do I get tftp to response on eth1?Which networks are connected to each card? What is the IP/subnet of the client? You could be connecting through eth1 to tftpd, but the server is sending the packet back out eth0. The client would then refuse the connection as its coming from the IP address of eth0.
