I was trying to build up a pxe based booting system on my network which has a dhcp server. I am trying setting up a pxe server which would have tftp service and pxelinux.0 file

On running the client i found the following error :
PXE-T01: file not found
PXE-E3B-TFTP Error file not found
PXE-M0F exiting Intel boot agent

I have checked the tftp service that runs fine on the system , what could be the probable error , the dhcpd.conf also seems to be OK.

The problem is solved, i made a few changes in my dhcp.conf file and it worked , my dhcp conf file now looks like this

1 option domain-name "cse.iitk.ac.in cc.iitk.ac.in iitk.ac.in junta.iitk.ac.in";
2 #option domain-name "cse.iitk.ac.in";
3 option domain-name-servers dns.cse.iitk.ac.in, dnsbak.cse.iitk.ac.in, 172.31.1 .1;
4 option routers 172.27.16.254;
5 option subnet-mask 255.255.240.0;
6 option netbios-name-servers 172.27.16.7;
7 option nis-domain "cse";
8 option smtp-server 172.27.16.2;
9 default-lease-time 600;
10 max-lease-time 7200;
11 next-server 172.27.17.48; # this was the address of my PXE server
12 use-host-decl-names on;
13 filename "linux-install/pxelinux.0"; # this line made the diff my earlier file name was /tftpboot/linux-install/pxelinux.0

14
15 subnet 172.27.16.0 netmask 255.255.240.0 {
16 }
Thus a minor correction in line 13 made all the difference

I have been looking all over the web for a solution to this issue.

Thanks, this fix did the trick.

I agree: THANK YOU! This fixed my problem too!

Thanks.... This fixed my problem....

I get this exact same error on FC10 running FOG 0.26. I've checked dhcp conf, and it is simply "filename=pxelinux.0". I assume this is correct because I don't have the "linux-install" subdirectory. I am using a windows server for DHCP and I have configured items 066 and 067 properly in Scope Options.

Has anyone run into this problem and had success with another solution?

...it was caps lock. HAH I actually had "PXEBOOT.0" on my windows server. I feel like a doof. Good thread anyway!

Hi Guys,

Where is my DHCP.conf located?

I've tried sudo nano /etc/dhcp.conf

Thanks,

Jed

Metaljed,

First the system must be setup as a DHCP server. Then the file you will need to edit is /etc/dhcpd.conf.

I was sooooo... happy to see this error
In F12 KDE live I ended up using the bundled dnsmasq server - (a lightweight combination dhcp/bootp/tftp server)
only for the bootp/tftp server part (dnsmasq 2.48-4.fc12 i686 (281k).

The yum installed tftp-server (0.49-5.fc12 i686) I just could NOT get to send the bootfile along -
some firewall iptables inserts helped it get a little farther -
but I spent days in snort and tcpdump figuring out what ports were the holdup - yada yada yada.

When I very first tried this dnsmasq server by itself I didn't get the config right to get the DHCP offer
yet the service dnsmasq status was definitely running . . .
(to a Sharp AL27 MobileAMD 64 laptop using Intel UNDI, PXE-2.0 build 082) . . .
so I turned on the F12 dhcpd server (4.1.0p1-13.fc12 i686 (2.1M) just to do the dhcp offer part . . . and to my amazement

. . . Voila ! . . . I see this beautiful error!

So, my very last LAN boot error message . . . a double posting of /ploplinux/ in the path -
a simple fix !

Good thread anyway!

Hi,

I am using Debian as my OS. My tftp server is running fine. The pxelinux file actually present on server X but served via NFS to a server Y which is my tftp server. I get this error while pxe booting another client. Is there any way I can get rid of this error?

Thanks,
Cheers,
Swati

Hi,

Also, I wanted to ask, what is the correct syntax of providing the path of the pxelinux file in the dhcp.conf file? Does it have to be the absolute path of the file. For example, in my case the path is

/srv/tftp/fai/pzelinux.0

Does that mean, the entry in the dhcp file must be

filename /srv/tftp/fai/pxelinux.0 ?

Thanks a ton!
Cheers,
Swati

Hello,

I have got the same problem:

PXE-T01: file not found
PXE-E3B-TFTP Error file not found
PXE-M0F exiting Broadcom PXE ROM.

my dhcpd.conf is located in: "/etc/dhcp3/dhcp3.conf"
my pxelinux0 is located in: "/tftpboot/pxelinux.0"

I´m a Linux-Newb and tried to google myself through this problem but I´m some kind of stuck at this point.

I hve already tried the following entrys:

filename "pxelinux.0"; <-- I also copied the file to the directory of the dhcp3.conf

filename "/tftpboot/pxelinux.0";
filename "/../../tftpboot/pxelinux.0";
filename "../../tftpboot/pxelinux.0";
filename "/~/tftpboot/pxelinux.0";
filename "~/tftpboot/pxelinux.0";

After I edited the config, I always used "sudo/etc/init.d/dhcp3-server restart"
I hope this enought to load the whole file again and use the changes.

What am I doing wrong?

vision2, Check /etc/default/tftpd-hpa

and make sure TFTP_DIRECTORY is set to the directory with pxelinux.0


hope this helps.

I dont want to hijack anyones thread, but I'm also having the same problem and was wondering if I can post here, or should I start another thread?
