Hi all,
I have a centos 5 box I have setup, current with updates. (I have done
this many times on centos 4).
I did the yum install tftp-server, changed the /etc/xinetd.d/tftp file
as shown.
# 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 = -v -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
Did the service xinetd restart.
Now from another computer on the network I am trying manually "tftp IP
-c get myfile"
and nothing happens.
/tftpboot permissions are: drwxr-xr-x 4 root root 4096 Oct 2 16:26
tftpboot
the myfile is also world readable in that directory.
I have disabled the iptables "service iptables stop".
I ran "tcpdump port 69" to show me all tftp traffic an I see NOTHING
when I manually
run the tftp command above on another computer.
The second computer can ssh into the server no problem.
I can, on the server, to tftp localhost -c get myfile and that works fine.
What or HOW can I determine why I cannot tftp from that machine?
This seems so straight forward.
Thanks, frustrated me...
Jerry
Do you have any networkr device between your client and your server ? When running tcpdump, do you see any packet when runing "telnet localhost 69" ? Do you have multiple NIC on your server ?

What does tcpdump port 69 show on _client_ when you try tftp'ing? I get: server tcpdump port 69: 14:33:28.366478 IP mk.crc.dk.34258 > server1.crc.dk.tftp: 20 RRQ "test.dat" netascii client tcpdump port 69: 14:33:28.366884 IP mk.crc.dk.34258 > server1.crc.dk.tftp: 20 RRQ "test.dat" netascii Mogens -- Mogens Kjaer, Carlsberg A/S, Computer Department Gamle Carlsberg Vej 10, DK-2500 Valby, Denmark Phone: +45 33 27 53 25, Fax: +45 33 27 47 08 Email: mk at crc.dk Homepage: http://www.crc.dk
