@TheGreatDoc When I go to settings, I don’t see Discovery. The other tab options are Alert Settings, External Settings and Webui Settings.
Thanks.
I must be on an old version, I only see the options I listed above, only 4 tabs.

What version are you running? You should update your install 
I am trying to update it, right now. I’m getting a warning stating that ./daily.sh should be manually ran, and when I run sudo ./daily.sh I still see the same warning after I run validate.php.
Also, I need to update PHP, but I think I ran into an issue last time I ran this on my other LibreNMS install. What is the best way to update PHP? Is it a simple command I can run?
current librenms version is - 1.48.1-25-g21192a9
daily must be run as librenms user. If you run it with sudo, you’ll break your install…
(I seem to have got in a bit of a situation here, with validate.php and daily.sh unable to complete)
Ok, I was not running those commands with the librenms user, as you stated. I am trying to use the command ‘su - librenms’ to switch to the librenms user and when it asks for the password I’m using the password for my admin user, which isn’t working. I’m not sure which password it needs. If there is a default password for the librenms, I’ll have to try to find that password. I’m getting authentication failure when I attempt to switch to librenms.
Part of the problem I have is that I have multiple librenms servers. One for production and one on a personal network, not affiliated in any way with the production librenms server. They were installed at different times with different OS versions and I didn’t realize there were this many differences between my two systems (which is nobody’s fault, just a note). I am updating my documentation to reflect respective changes in both servers. I bring this up because I’ve asked similar questions, but never really indicated that they were for different systems.
Thanks.
To get to user “librenms”, you can start from root and then type “su - librenms”.
Ok, I typed:
sudo -s to get me into root, I see root@severname:~#
Then I typed:
su - librenms and all I see now is $ with the cursor flashing. I haven’t seen this before and I know I’ve successfully ran ./daily and ./validate properly, in the past.
I think I am missing something.
Thanks.
su - librenms doesn’t work, well, it works, but it takes me to a $ prompt.
Typing ‘su librenms’ does switch the prompt to ‘librenms@servername:/root$’ but I think it is running with root permissions based on the googling I’ve been doing. I don’t think I want to proceed in this mode.
Not sure how to proceed.
Thanks.
You get $ console coz librenms doesnt have the bash shell. You can change it to bash
chsh --shell /bin/bash librenms
Thanks @TheGreatDoc this gets me a bit further, but now I’m seeing PAM: Authentication Failure. I tried with no password and I also tried with the only password I use for my admin account. Thanks.
The command I posted is to be run by root (or sudo if ubuntu) that way you change the librenms user shell to bash.
Apart from that, you can also configure your install directly in config.php
https://docs.librenms.org/Extensions/Auto-Discovery/#allow-duplicate-sysname
Hope that helps
When I run the command using sudo, it brings me back to the same prompt I am already in, which is my admin username@servername, shouldn’t that change to reflect the librenms user?
I don’t think I want to mess with config.php, yet, and that will only solve the duplicate name issue. It seems that I’m not fully up to date/having issues with daily.php because of the user name issue.
If I can’t get past this, I’ll need to leave this server as is since it won’t update, which isn’t a desired outcome.
Thanks.
After running that command, if you sudo su - librenms should get the normal bash shell for the user
Ok, good news, one system is fully up to date and I see the duplicate name option in the settings section, that you pointed out. (ubuntu 18)
Bad news, my second system is receiving two warnings. Both warnings are under the update section. One fix is to run ./daily.sh by hand, which I am, and I am not receiving any errors.
The other is to update PHP, which I’m not sure how to do, yet. I’d like to solve the ./daily.sh error before tackling the PHP update. (ubuntu 16)
Thanks.
What error do you get?
No error, just the two warnings I posted above.
Thanks.
