Nagios Support Forum

Hi,

when trying to load a custom MIB via the Web gui - i am getting the error message below:

MIB could not be installed - directory permissions may be incorrect

I have looked around the forum and found some suggestions to run the following

chown root:nagios /usr/share/snmp/mibs
chmod g+w /usr/share/snmp/mibs

Unfortunatly this has not solved the problem - does any one know of a fix ?

currently runing

NagiosXI v5.2.8

Thanks

What is the full output of these commands?

output below

Many thanks

Try changing the permissions to the following and see if that works for you.

unfortunately it still the same result when i attempt to upload a custom MIB

its also the same if i try to load a custom Plug in from the web GUI - i get the same message

Plugin could not be installed - directory permissions may be incorrect

Can you post the MIB file you are trying to upload and the /etc/php.ini file from the XI server?

please see attahed ..
The MIB attachment above is actually a .mib file extension - the forum does not allow upload of .mib file extensions
many thanks

Found it, it is the max upload size setting in the php.ini file
Edit the /etc/php.ini file and change this lime from to Save the file and run this to restart Apache. This will allow you to upload files to the server with the max size of 20 Meg.
This should be large enough for most files, if not, you can increase it again.
