mPower - Read-only file system about mpower-tools

[Basicek1]

Thank you very much for a quick response to my problem. It was really just not setting up a DNS server ...
Thank you for your project

[magcode]

That is very strange!

could you please execute some commands manually?

LOCALDIR="/var/etc/persistent/mqtt"
echo "my localdir is $LOCALDIR"
ls -la $localdir

also please post the contents of your (downloaded) install-client.sh

[Basicek1]

Thank you for the answer, I immediately tried:

MF.v2.1.11# LOCALDIR="/var/etc/persistent/mqtt"
MF.v2.1.11# echo "my localdir is $LOCALDIR"
my localdir is /var/etc/persistent/mqtt
MF.v2.1.11# ls -la $localdir
drwxrwxrwx 2 admin admin 60 Jan 1 1970 .
drwxr-xr-x 7 admin admin 160 Jan 1 1970 ..
-rwxr-xr-x 1 admin admin 3106 Mar 31 09:01 install-client.sh
MF.v2.1.11#

[magcode]

please do a cat install-client.sh and post the output

[Basicek1]

I copied content from install-client.sh and saved in to mPower via the "vi" editor:

`#!/bin/sh

LOCALSCRIPTDIR=$LOCALDIR/client

I'd recommend to download it using the provided script

wget --no-check-certificate -q https://raw.githubusercontent.com/magcode/mpower-tools/master/mqtt/client/install-client.sh -O /var/etc/persistent/mqtt/install-client.sh;
chmod 755 /var/etc/persistent/mqtt/install-client.sh;

[Basicek1]

I made a restart of mPower and tried the recommended:

BusyBox v1.11.2 (2015-04-06 14:24:36 PDT) built-in shell (ash)
Enter 'help' for a list of built-in commands.

MF.v2.1.11# wget --no-check-certificate -q https://raw.githubusercontent.com/mag
code/mpower-tools/master/mqtt/client/install-client.sh -O /var/etc/persistent/mq
tt/install-client.sh;
MF.v2.1.11# chmod 755 /var/etc/persistent/mqtt/install-client.sh;
MF.v2.1.11#

[magcode]

Good. Now execute the install script again!

/var/etc/persistent/mqtt/install-client.sh

[Basicek1]

if I look at install-client.sh is empty - it is zero size

MF.v2.1.11# ls
bin data mqtt
cfg log rc.poststart
MF.v2.1.11# cd mqtt
MF.v2.1.11# ls
install-client.sh
MF.v2.1.11# ls -l
-rwxr-xr-x 1 admin admin 0 Mar 31 10:47 install-client.sh
MF.v2.1.11#

[magcode]

Your device has internet access?

Please post the output of

wget --no-check-certificate https://raw.githubusercontent.com/magcode/mpower-tools/master/mqtt/client/install-client.sh -O /var/etc/persistent/mqtt/install-client.sh;

Ok. That's it then. Seems like a DNS issue.
You need to fix that and afterwards you can try the installation again.

Ammended the docs:
