[quote=“Tom Elliott, post: 18128, member: 7271”]okay, thanks.
Maybe this fixes it fingers crossed lol.[/quote]
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?

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?

Not that I am aware. This machine is an old dell Optiplex 740 and only used for FOG -
Okay,
Run this command:
[code]sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/’ /etc/sysconfig/selinux[/code]Then reboot and try again!

HOLY MOTHER OF GOD! I just rebooted my laptop to try the tftp command from another machine and I forgot it is set to boot from network. And guess what!? It booted up into FOG! WOOOT! Many Thanks! If you are ever in Jackson, TN I’ll owe you a beer!
-
Glad I could be of some help.
-
Now I can head home! Thanks again!

Based on the results, my guess is somebody already had this same type of issue but disabled it with:[code]setenforce 0[/code] on the server, which is why it was working. On the next reboot, because it wasn’t disabled before, it just reset to enforcing.
