Hello everyone.

I'm having a probelm getting my tftp server to work at the moment. I'm using RedHat 9.0 and have installed tftp-server-0.32-4.i386.rpm and tftp-0.32-4.i386.rpm that I got from

I've configured:

[root@amsterdam /]# cat /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 = -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4

[root@amsterdam /]# cat /etc/hosts.allow
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.

and restarted xinetd. port 69 is listening:
[root@amsterdam /]# netstat -na | grep 69
udp 0 0*

and I made sure to allow it in my iptables:

ACCEPT udp -- anywhere udp dpt:tftp

The directory has the right permission:

drwxr-xr-x 3 root root 4096 Apr 21 10:09 tftpboot

as well as the file I'm trying to get:

-rwxr-xr-x 1 root root 1197084 Apr 21 10:09 oper.52.enet

The problem I'm having is that when I try to tftp that file (either from the machine itself or from a remote machine) all I get is:

Apr 21 14:10:03 amsterdam in.tftpd[13955]: tftpd: read(ack): Connection refused
Apr 21 14:10:08 amsterdam in.tftpd[13956]: tftpd: read(ack): Connection refused
Apr 21 14:10:13 amsterdam in.tftpd[13957]: tftpd: read(ack): Connection refused
Apr 21 14:10:18 amsterdam in.tftpd[13958]: tftpd: read(ack): Connection refused
Apr 21 14:10:23 amsterdam in.tftpd[13960]: tftpd: read(ack): Connection refused

Any/all help would be VERY much appreciated.

I havent' used tftp in linux, but are there error logs created that may tell you why the connection is refused? Maybe try to telnet to port 69 to see if it is actually listening for other hosts.

Hope this can get you going in the right direction.

I had similar problems using TFTP on Fedora Core 1. Couldn't copy images to or from any Cisco device. I had to do two things. First make sure iptables isn't running.

You can stop it with:
service iptables stop
as root user.

Next edit the /etc/xinetd.d/tftp file and rem out the line that reads
flags = IPv4

and restart the services with

service xinetd restart

again as root user.

Hope this helps.
