PXE-E32 tftp open timeout

efilnei · 04-27-2009, 05:03 PM

Hi, i'm configuring a LTSP server with CentOS 5.3

I have all installed (dhcp, tftp, nfs and xdmcp). I have to run the clients with PXE.This is my dhcpd.conf:

Code:

# dhcpd.conf

ddns-update-style             ad-hoc;

option subnet-mask            255.255.255.0;
option broadcast-address      192.168.0.255;
option routers                192.168.0.132;
option domain-name-servers    192.168.0.132;
option domain-name            "your_domain.org";   # You really should fix this
option option-128 code 128 = string;
option option-129 code 129 = text;


get-lease-hostnames           true;

next-server                   192.168.0.132;
option root-path              "192.168.0.132:/opt/ltsp/i386";

subnet 192.168.0.0 netmask 255.255.255.0 {
    range   192.168.0.100   192.168.0.199;
    if substring (option vendor-class-identifier, 0, 9) = "PXEClient" {
        filename "/lts/2.6.9-ltsp-3/pxelinux.0";
    }
    else{
        filename "/lts/vmlinuz-2.6.9-ltsp-3";
    }
}

I think is all ok. When i run the clients, they get a IP from the DHCP server, but when they try to get the kernel, TFTP fails and give this error:

PXE-E32 tftp open timeout

I have tftp installed, and when i run "ltspcfg" i can see tftp is running, but i don't know what's the problem

Please help

Thanks! Sorry for the english, is not very good, hehe

Hi,
Yesterday, I am also faced the same problem and found solution.
* Be ensure that your tftp is running before you boot your client.
I found that $/etc/init.d/tftpd-hpa start has no effect until I modified the file /etc/default/tftpd-hpa. Just replace YES instead of NO in the first line. It should be like, RUN_DAEMON="yes"

* Now run $/etc/init.d/tftpd-hpa start. You will get the response.
* Now check your client.
Hint : Try "cat -f /var/log/syslog" in ur terminal. You will get the info like,
Apr 29 11:30:15 rtlinux-desktop dhcpd: DHCPDISCOVER from 00:1c:c0:6e:da:4a via eth2
Apr 29 11:30:16 rtlinux-desktop dhcpd: DHCPOFFER on 192.168.1.49 to 00:1c:c0:6e:da:4a via eth2
Apr 29 11:30:18 rtlinux-desktop dhcpd: DHCPREQUEST for 192.168.1.49 (192.168.1.1) from 00:1c:c0:6e:da:4a via eth2
Apr 29 11:30:18 rtlinux-desktop dhcpd: DHCPACK on 192.168.1.49 to 00:1c:c0:6e:da:4a via eth2
Apr 29 11:30:18 rtlinux-desktop in.tftpd[32186]: connect from 192.168.1.49 (192.168.1.49)

-Prakash.

Hi. Thanks for answer. I was trying that you say but:

i don't have script "/etc/init.d/tftp-hpa"
i don't have script "/etc/init.d/tftp

And

i don't have file /etc/default/tftpd-hpa

I have CentOS 5.3 :S ¿What's the problem? I have installed tftp package

Hi again. I be searching (again) from Google the same problem. I have found to many posts, but no luck...

Too many people said that the problem is the firewall, and i had to open some ports (69); maybe tftp was blocked, but no is the problem...

On CentOS systems the tfpt daemon is called xinetd. You need to configure the tftp file inside /etc/xinetd.d and change to NO in the conf file where it says DISABLE.

Once you do that, your tftp server will be working fine.

Good luck!
