NetXMS Support Forum

Hey, there. I just installed the latest version of NetXMS server and netxms agent, in this case Linux agent on Ubuntu 18.04

With this in mind I decided to add the the Sample agent's configuration file in the nxagentd.conf

I stopped the netXMS server and I restarted. However, I could not to connect to the server. The Desktop Managment tool sent back the following popup window (I attach a screenshot). I checked the status of netXMS server out. In the terminal window sent back the following error.

sudo systemctl status netxmsd

Dec 04 19:03:26 hpserver1 systemd[1]: netxmsd.service: Failed with result 'exit-code'.


Finally, I checked the netXMS server log file out. I attach the latest lines.

that's agent log file, not server.

Hi, Alex I appreciate your help. Your right.

the latest lines of the netxmsd log file

try starting netxmsd process from command prompt in foregroud mode:

netxmsd -D 6

This will start it with 6-th level or debug and will put all messages that are written to log file to the console. After it terminates, share the output.

Hi, Filipp I appreciate your sooner reply to my post.

netxmsd -D 6
Using configuration file "/etc/netxmsd.conf"
FATAL ERROR: Cannot open log file

But the netxmsd.conf file is in the /etc directory

ls -la /etc/netxmsd.conf
-rw-r--r-- 1 root root 812 Dec  4 20:00 /etc/netxmsd.conf

It's ok with /etc/netxmsd.conf - it's just printing what config file it's using. The error is "FATAL ERROR: Cannot open log file".

I can think of two reasons for that:
- you are starting it as regular user, but the log file was previously opened by netxms running under root (because systemd lauches it this way). So under regular user you don't have rights to write to same log file. Try running under root user.
- check log file configuration in /etc/netxmsd.conf. Does it point to non-existing folder?

Hi, Filipp. I ran the netXMS server under root user:

root@hpserver1:~# systemctl start netxmsd
root@hpserver1:~# systemctl status netxmsd

The first lines of the netxmsd.conf file

#DebugLevel=3

## Database configuration.

## Option #1 - SQLite (for test installations only):

#DBName=/var/lib/netxms/netxms.db

Nothing to point to the non-existing folder.

try deleting /var/log/netxmsd and running
netxmsd -D 6
again.
Wil the error be the same?

Hi, Filipp

I deleted the /var/log/netxmsd file

josemb@hpserver1:~$ netxmsd -D 6
Using configuration file "/etc/netxmsd.conf"
FATAL ERROR: Cannot open log file

You are running netxmsd as user "josemb" which does not have write access to /var/log.
Either run netxmsd as root, or change configuration file location.

According to systemctl output, netxms is installed in /usr, but it tries to load modules from /usr/local/bin - this looks like you mixed binaries from different versions.
I recommend to clean both versions, then configure and make install again.

Which distro do you use?

Hi, Alex. I am using Ubuntu server 18.04. Question: How can I clean both versions?
Thanks in advance.

I would do the following way:
apt remove "netxms*"

Then find and delete the following files on the file system:
libnx*
libnetxms*

And then install netxms again - install  netxms-release package and then netxms-server, netxms-agent and database driver package.

Hi, Filipp. Thanks for your sooner reply to my post. I have a Database question: we have a current netXMS database. With this in mind. Do I do

nxdbmgr upgrade or

nxdbmgr init

Thanks in advance
