Plugin could not be installed - directory permissions may be

[ecarrasq]

When I try to add a Plugin using the "Admin > Manage Plugins" I get the following error message:

Plugin could not be installed - directory permissions may be incorrect.

Info of my system:
**NagiosXi 2011R1.3
**Linux Distribution and version: CentOS 5.4 32bit
**VMware Image: yes
**No special configurations on the system.

I've added numerous plugins about 3 weeks ago with no problems, but not able to now.
Note: I ssh into my Nagios server and looked at the owners for /usr/local/nagios and it was "apache". Apache was also owning most the configuration files along with some directories such as /usr/local/nagios/etc

Don't know if this is related, or how it happened.

Please help, thank you.

What plugin are you trying to install in particular?
Are you having issues with this plugin only or now you get "Plugin could not be installed - directory permissions may be incorrect" every time you try to install a plugin?
Run in terminal (as root):
# /usr/local/nagiosxi/scripts/reset_config_perms
# service nagios restart
# service httpd restart
Try again installing the plugin again. If you are still having issues, run in terminal:
# ls -l /usr/local/nagios
# ls -l /usr/local/nagios/libexic
Post the output of these two commands, so we can take a loot at it.

check_ssh_faillogin.tar.gz but happens with other plugins I try to install as well.

Unsuccessful with the first suggestion:

Run in terminal (as root):
# /usr/local/nagiosxi/scripts/reset_config_perms
# service nagios restart
# service httpd restart

OK. Run in terminal:

# /usr/local/nagiosxi/scripts/fixperms.sh

This command will fix your permissions, but after this you have to run:

# chown root.nagios /usr/local/nagiosxi/scripts/reset_config_perms
# chmod u+s /usr/local/nagiosxi/scripts/reset_config_perms
# chown root.nagios /usr/local/nagiosxi/scripts/reset_config_perms.sh
# chmod u+s /usr/local/nagiosxi/scripts/reset_config_perms.sh

And finally:

# service nagios restart
# service httpd restart

Try this and let us know if it worked.

SUCCESS!!!!
New plugin was installed successfully.
THANK YOU!!!

I did what you suggested below and all works well now:

# /usr/local/nagiosxi/scripts/fixperms.sh

This command will fix your permissions, but after this you have to run:

# chown root.nagios /usr/local/nagiosxi/scripts/reset_config_perms
# chmod u+s /usr/local/nagiosxi/scripts/reset_config_perms
# chown root.nagios /usr/local/nagiosxi/scripts/reset_config_perms.sh
# chmod u+s /usr/local/nagiosxi/scripts/reset_config_perms.sh

And finally:

# service nagios restart
# service httpd restart
