Topic: PXE boot problem

[veebr0]

Dear all, I use the pxeboot service to install some machine images in my network all in the past work find however today when I try to boot from the network   the machine does get the IP address and of course the boot machine never is loaded.

when I run the command : tail -f /var/log/messages I can see the following error
Apr 24 17:32:09 serverfp sshd(pam_unix)[3120]: session closed for user root

Note: The only now in my network is a new one firewall.

Thanks in advance,
Eviny

This has nothing to do with your problem, it is just a message that a SSH session for the root user was terminated.

Note: The only now in my network is a new one firewall.

This might be the cause of your issue. Not sure if PXE boot uses some ports you might have blocked, not do we know the network layout, but perhaps you can easily try if the firewall is causing the issue by reverting back to the old situation and seeing if it all works again. If so, you will have to investigate why your firewall is causing PXE boot to fail.

Dear Friends thanks for your prompt answer, following your addressed, I  revert all as a original, but the problem still persist, but the case is very trick, I selected a random machine to start via pxe boot the the first time it work fine, but in the second time does not work, I selected another machine and the scenery is the same.

My Original network is:
Internet---Router---Switch--SME server (Only Server), really only use SME for File and Printer Server.

I want to implement:
Internet-Firewall---Switch---SME
Into the firewall one board is connected to our wan, and the other to our LAN directly to our switch, and the sme server is connected directly to the Switch as are all machines (5), My sme server is the responsible to offer our DHCP configured to provide as a default the gateway the firewall IP, That is correct?

Note: I was investigated and the port that need to be open are: 60, 66, 67, 68, 69 and ,4011 all are opened into the fireall

I really appreciated any steps or recommendation to check some logs in order to to validate into sme if the services is running on, or how to check when the machine is requesting the DHCP via pxeboot.

Thanks in advance,
