Running a Linux PXE Administrating TFTPBoot Question

So folks how do you administer TFTPBoot on a PXE? This is probably a basic question but I cannot find the binary. It does not show up as a service in the /etc/rc.d dirctory

Also I cannot find a tftpdboot binary using the find. Also I do not see in binarys in the /tftpdboot directory nor is anything running with that name when I do ps -ef |grep ftp

Any thoughts, thanks in advance

It is usually part of xinetd.

In the configuration file /etc/xinet.d/tftp you should have

disable         = no

Open in new window

RPMS to install:

tftp-server-0.49-7.el6.x86_64
tftp-0.49-7.el6.x86_64

Open in new window

Starting Service

service xinetd start

Open in new window

Checking the service

netstat -nulp | grep 69

Open in new window

You will see something like
udp 0 0 0.0.0.0:69 0.0.0.0:* 28979/xinetd

Thanks for the suggestion that configuration file is configured that way already. Is there a way to manually kick xinet.d in the but to makes sure tftpdboot is started?

Thanks guys port 69 is open.

udp 0 0 0.0.0.0:69 0.0.0.0:* 2564/xinetd

Also the port of NFS is open

tcp 0 0 *:nfs *:* LISTEN

And disable is configured as well

[root@pxeserver xinetd.d]# cat tftp

disable = no

Here is a screen shot to show where it getting hung up on. It hangs out at "Booting the Kernel" for a while than boots back up with no new OS on it.

Actually here is some new data that may help. I telneted to the serial console on a client that was trying to load the PXE image. It looks like there is an error message that is missing a file. This happens on all the images on the box (there are three of them) so I am not sure which file it could be referring too

What Linux distro are you using?

You should have some messages in your log files, on the server side. They may help understanding the issue.
