External Parameter fail for agent daemon mode

[xatteg]

Hi All,

I'm using external parameters in nxagentd.conf file, one of them:

ExternalParameter = CF2PRIVATEMEM:privatemem.sh

If I launch nxagentd -f -D 9  it executes and reads the parameter correctly

[12-Aug-2016 14:30:59.404] [DEBUG] [session:0] Received message CMD_GET_PARAMETER

However if I launch in daemon mode nxagentd -d -D 9  then I get the following

[12-Aug-2016 14:29:31.930] [DEBUG] [session:0] Received message CMD_GET_PARAMETER

Which is wrong. Current version of server and agent is 2.0.5 and it does not work here.
When I had version 1.2.17 it worked correctly.

I figured out that agent in daemon mode reacts with pain on sudo command in external script.
E.g. if script contain something

#!/bin/bash
echo 300

Than it works, but if we add sudo

sudo -u someuser echo 300

It does not. Did anyone run into this?

Try to remove "Defaults requiretty" from /etc/sudoers

This worked!

Many thanks!
