TFTP Open Timeout
-
sounds like a problem I’ve encountered before (when I upgraded my Ububntu to 13.04) appears to be the the tftp service starts when the network isn’t up and can’t bind to any interfaces( anybody let me know if I’m wrong) by changing the start up script you can delay the service initializing until the network is up.
edit (nano or vi) " /etc/default/tftpd-hpa " and add “sleep 30” on the top line so it looks like :
[I][B]sleep 30[/B][/I]
[I][B]# /etc/default/tftpd-hpa[/B][/I]
[I][B]# FOG Modified version[/B][/I]
[I][B]TFTP_USERNAME=“root”[/B][/I]
[I][B]TFTP_DIRECTORY=“/tftpboot”[/B][/I]
[I][B]TFTP_ADDRESS=“0.0.0.0:69”[/B][/I]
[I][B]TFTP_OPTIONS=“-s”[/B][/I]will have to restart the service or reboot
let me know how you get on - should work though
also confirm that option 66 & 67 on your dhcp scope/server option points to your sog server (option 66) and “pxelinux.0” ( zero, for option 67)
-
Yup, my DHCP options 66 and 67 are set correctly. I can try to “sleep 30” and see what happens but if that was the case (that TFTP starts too early), wouldn’t I not be able to PXE boot into Fog at all?
I can PXE boot into Fog if I’m on the same subnet as the Fog server.
I cannot PXE boot into Fog if I’m on a different subnet as the Fog server.Either way, I’ll try in the morning and post how it went!
Thanks!
-
pxe from different subnet is ok - one way to quickly confirm is do a ps -A |grep tftp to see if its running if it is running but no process id then certainly try the sleep - let me know in the morning… will be evening for me
-
I just remoted in and ran “ps -A | grep tftp” and I get back nothing. I guess I’ll try the “sleep 30” tomorrow.
I’ll keep you posted!
-
Well, unfortunately the sleep 30 did not make a difference. Instead of waiting until morning, I remoted into my work PC, which remoted into an old imaging server, which remoted into a computer on a different subnet that had VMware Workstation on it.
Even with the sleep 30, Fog is still not working for other subnets outside of its own.
-
just check to see if the process is running again on the linux box “ps -A |grep tftp” if still not running check the logs /var/log on ubuntu
:$ ps -A |grep tftp
1184 ? 00:00:00 in.tftpd -
The service is still not running. ps -A|grep tftp comes back with nothing.
I tried to find a log in /var/log that looked like tftp but I could not find one.
-
nothing in syslog … can you post the syslog ?

Syslog says this:

so it is proceesing the requests ok - try adding a simple task like mem test or inventory - should all work ok but to get it to boot local have a look at this [url]http://www.fogproject.org/wiki/index.php/Boot_looping_and_Chainloading[/url] - can you post the default file /tftpboot/pxelinux.cfg/default

just try updating PXELINUX as described [url]http://www.fogproject.org/wiki/index.php/Boot_looping_and_Chainloading[/url]
-
I did. It had no effect.
-
On the subnet where I have my Fog server setup, it PXE boots just fine. On any other subnet, it will not get a DHCP address which leads it to be unable to PXE boot.
-
so if that subnet isn’t getting dhcp - is there a scope set on the windows box for that subnet with a pool set - is the pool exhausted ? check to see if the pool isn’t exhausted …
-
i was under the impression it was getting an ip address ??? you syslog post [B]“sent /tftpboot/fog/bg.png to 10.120.100.41” [/B]
right ?[B][/B]
-
also check to make sure you are able to route to your fog server …
-
firewall rules ???
-
The pool is definitely not exhausted. If it boots to Windows, it gets its DHCP address.
Yes (to your second post).
In my internal network, there is no firewall whatsoever.
-
tftp on fog ok - running confirmed
dhcp - giving addresses options 66&67 set ok
routing ok
firewall rules (any,any) nothing should be blocked …ok
try from the windows box (10.120.100.x subnet right?) command prompt tftp [I]foghost[/I] get pxelinux.0 ?
