Fog was working fine until a power outage

[quote=“Tom Elliott, post: 18114, member: 7271”]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?[/quote]
I get the following:]# tftp -4 localhost
tftp> get
(files) pxelinux.0
Error code 0: Permission deniedI am running as root.

[quote=“Tom Elliott, post: 18116, member: 7271”]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]
The firewall is off.

what is the output of the command:
[code]umask[/code] -

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.

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.

Same error message as well?

is selinux running per chance?

Yes sir. same error Permission Denied.
Should I try Percussive Maintenance?

sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 24
Policy from config file: targeted -
Lol, no!
Can you verify that SELINUX is enabled/disabled? To do so, what’s the output of:
[code]cat /etc/sysconfig/selinux[/code]It should, hopefully, look like this:
[code]# This file controls the state of SELinux on the system.SELINUX= can take one of these three values:
enforcing - SELinux security policy is enforced.
permissive - SELinux prints warnings instead of enforcing.
disabled - No SELinux policy is loaded.
SELINUX=disabled
SELINUXTYPE= can take one of these two values:
targeted - Targeted processes are protected,
mls - Multi Level Security protection.
SELINUXTYPE=targeted[/code]
Especially with the SELINUX=disabled line!
-
Ah ha!
Does your system need SELINUX running?
