Apply Config fails with Unknown Error. Please Run: fwconsole reload --verbose

sgseidel · March 23, 2021, 5:37am

FreePBX 15.0.17.24 / Asterisk 16.15.1 / all modules up to date

As the subject line states, when I run Apply Config, the dialog says:
"Error! There was an error during reload: Unknown Error. Please Run: fwconsole reload --verbose

$ sudo fwconsole reload --verbose
Reload Started

In PJSip.class.php line 502:

[Exception]
Asterisk will crash if sip_server is blank!

I have tried running:

$ sudo yum update
$ sudo fwconsole ma upgradeall

and rebooting FreePBX, but the issue is the same.

I deleted two chan_pjsip trunks, ran Apply Config again, and this time it completed without an error.

When I log in to FreePBX, whether via the console or ssh, the following warnings are shown:

If I log out and then log back in, the same warnings appear.

How can these warnings be addressed?

Well, that looks better.
(If I remember correctly, I’ve done this once or twice before. Let’s see how long it will last.)

Run as root

sgseidel · March 25, 2021, 5:21am

@jfinstrom Thanks for your reply.

You say “run as root.” I’ve been a UNIX system admin for (too) many years, and as a matter of policy I’ve learned to try to avoid running things as root unless absolutely necessary. If you check the commands that were run above, everything was run as sudo.

Can you explain why you recommend running these commands as root instead of sudo, and why running on CentOS would be any different than on other UNIX or Linux systems?

sgseidel · March 25, 2021, 5:51am

Absolutely no changes were made to the OS, nor were any permissions changed by me (and I’m the only one authorized to use this computer). However I see when I logged in again today, the problem re-surfaced:

Anyone have advice?

jfinstrom · March 25, 2021, 4:24pm

fwconsole has to be run as root. If you don’t it won’t work. Fearing root is a very debian thing to do. I’ve been in and out of systems for 20 years as root and almost nobody has died. Seriously though it is just how it works.

jerrm · March 25, 2021, 4:37pm

I don’t know where the sudo dogma originates, but I’ve had to fix more systems from “sudo” admins than those logged in as root.

If you don’t trust yourself at the root prompt, you probably shouldn’t trust youself with sudo either.

Too many folks just start automatically prefixing commands and might as well be logged in as root.

dicko · March 25, 2021, 4:41pm

If you insist on using sudo, do sudo -i to get the same environment as root, the relevant sudoer has effectively logged in as a root login without knowing root’s password, without an argument, sudo -i starts a root login $SHELL (from root’s environment).

This works even on RH based systems

sgseidel · April 18, 2021, 2:51pm

@jerrm I don’t want to start a flame war here, but I can tell you where the “sudo dogma” originates, at least from my point of view. It’s in response to the “cowboy root” dogma, where someone less qualified than they think (sometimes “the boss”) demands the root password and proceeds to log in every single time as root. (Cue rolling eyes and groans from the rest of the technical staff.) I’ve seen this happen a few times, and is one reason all UNIX-like systems I’ve worked on, Solaris, HP-UX, Linux, FreeBSD, SCO UNIX, macOS, and dozens more, are designed to limit the use of root with the sudo command, or even better, prevent someone from logging in directly as the root user.

I have no problem if someone with proper skills wants to log in or "su - " as root. But log in, do your work, and don’t forget to log out.
