tftp server failed

Problem solved http://wiki.systemimager.org/index.php/HOWTO_Net_Boot_with_SystemImager_3.4.1


Hi, I'm stuck on this one error for the last 6 hours and I desperately need help. Help please!
I've found one other thread and there was no solution posted. Here's what everything looks like

[[root@localhost ~]# cat /etc/xinetd.d/tftp
# default: off

# protocol. The tftp protocol is often used to boot diskless
# workstations, download configuration files to network-aware printers,

socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot -r blksize
disable = no
}

So that's what's going on so far i've heard some things saying that its bugged and you have to hack it a bit. Please i'm lost!

[hunter123]

i was told to start tftp manually and go through and make sure tftp was working but i think that there;s a bug with systemimager. Can someone help me ?

[falko]

What's the output of netstat -tap? Did you start xinetd?

[hunter123]

i did start xinetd

heres the output

[root@localhost ~]# netstat -tap

Can you also post the output of
netstat -uap?

[hunter123]

[falko]

udp 0 0 *:tftp *:* 6327/xinetd
It's running. What's the output of iptables -L?

right now im trying to get the tftp server to connect to the localhost. I've done

chkconfig tftp on ; service xinetd start ; cp /etc/services /var/lib/tftpboot ; cd /tmp ; tftp localhost ; get services

and it's timing out!

so anyways i need some help ive disabled the firewall using /etc/init.d/iptables stop and setenforce0 to no avail please help!

[falko]

What happens when you stop vsftpd and set protocol = tcp in /etc/xinetd.d/tftp and restart xinetd?

[hunter123]

falko, I've just done about everything i can be told to do... Had a linux system admin walk me through it today and after 4 hours still couldn't find the problem. when I do tftp -v localhost -c get test, I get

[root@localhost ~]# tftp -v localhost -c get test
Connected to localhost.localdomain (127.0.0.1), port 69
getting from localhost.localdomain:test to test [netascii]
Transfer timed out.
[root@localhost ~]#


And my system logs say

Jul 9 07:53:51 localhost xinetd[9350]: FAIL: tftp address from=127.0.0.1
Jul 9 07:53:51 localhost xinetd[9175]: START: tftp pid=9350 from=127.0.0.1
Jul 9 07:53:51 localhost xinetd[9175]: EXIT: tftp status=0 pid=9350 duration=0(sec)

So i've edited just about everything and anything I can do. BTW your message before didnt do anything and the system admin told me to change it back to udp. Here's what my tftp file looks like

service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot -vv
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}

Any help?

[hunter123]

So Falko here's an update ive made a little but of progress. The Tftp server finally works but this time when i run si_mkbootserver instead of in the system logs saying that the connection was refused it now says


Jul 10 01:45:41 localhost xinetd[4672]: xinetd Version 2.3.14 started with libwrap loadavg labeled-networking options compiled in.
Jul 10 01:45:41 localhost xinetd[4672]: Started working: 1 available service
Jul 10 01:45:41 localhost in.tftpd[4682]: RRQ from 127.0.0.1 filename test9

[hunter123]

ok so falko heres probably my last post about this and it includes all the data ull probably need

for anyone who has this problem... I thought it's been solved however its the same thing again... the problem ive found out is that the script is making the file in tftpboot and tftping it to a local folder. Then its checking to see if the file it created is the same as the one in the local folder and its returning that its not.... maybe i should just remove the check, because i currently already know that the tftp works...
