Fog was working fine until a power outage
-
This may sound really odd, but can you try tftp from your fogserver with:
[code]cd
yum -y install tftp
tftp -4 localhost
get
pxelinux.0
exit[/code]Does this work?
-
This is also going to sound a bit odd, I think, but is there a firewall running on the FOG Server? Is iptables disabled?
To find out run:
[code]iptables -L -n[/code]If you get the text such as:
[code]Chain INPUT (policy ACCEPT)
target prot opt source destinationChain FORWARD (policy ACCEPT)
target prot opt source destinationChain OUTPUT (policy ACCEPT)
target prot opt source destination[/code]Then chances are it’s already disabled. If you get anything more than that run:
[code]chkconfig iptables off; service iptables stop[/code]

[quote=“Tom Elliott, post: 18113, member: 7271”]This is starting to make some sense.
The files that you’re working with are all currently 666, or rw-rw-rw- try chmoding all folders as 755 with:
[code]chmod -R 755[/code]Then perform:
[code]find /tftpboot -type f -exec chmod 744 {} ;[/code]This should put all files as rwxr–r-- which is what my system looks like. It will also place all the directories as their natural state of rwxr-xr-x[/quote]
Do I need to restart any services?
-
No, you shouldn’t have to restart any services that I’m aware of, is there a reason you ask?

I get the following:]# tftp -4 localhost
tftp> get
(files) pxelinux.0
Error code 0: Permission deniedI am running as root.

The firewall is off.

what is the output of the command:

Okay,
When you performed the install, did you have any special parameters involved. Such as:
[LIST]
[]Is your tftpboot folder in a location other than /tftpboot?
[]Is your tftpboot folder hosted on another filesystem?
[/LIST]
Has your system performed a filesystem check and/or is your filesystem on a RAID setup? Is it possible one of the drives has failed? -

The system as far as I know has not performed a filesystem check and I am not on a RAID setup. -
I’m going to ask that you reboot the server, if that’s okay with you?
But before you reboot type:
[code]touch /forcefsck
shutdown -rF now[/code]The shutdown -rF now command will force the system to shutdown and ensure that, if for some other reason, forcefsck will work on next reboot.

Rebooting now.

Maybe this fixes it fingers crossed lol.

had fingers and toes crossed but no luck.
When running tftp on the server I am still getting Error code 0: Permission denied

Can you show me the contents of:
[code]/etc/xinetd.d/tftp[/code]

can you perform
[code] tail -f /var/log/messages[/code]Then, in another terminal or tty (CTRL+ALT+[1-6]) try your tftp command.
NOTE: [1-6] is a representation of a number, so type the individual tty you want access to. 1 is the one you usually first see.
You should see the access hopefully.
Display the output of that here for clarity.
