BTW nextcloud is available for arm, not in the software-center (jet:) still looking for a co-maintainer as i’m not a nextcloud user)
yum install nethserver-nextcloud should do the trick.

I’m curios how far you can push the RPI4, you are suggesting quite a workload… :thinking:

I am … but i am going to try and see what the rpi4 can do and stress test it, keeping in mind that if need be (or even as an eventual feature) the infrastructure could be run over more than 1 unit but would still be very cost effective.

Think of the power savings in terms of both actual running costs and cooling i see many areas it could be useful

Example lets say you have a school where they limit the amount of students to 10 per class and due to lockdowns with covid they need remote learning infrastructure for 2 classes but as many commercial solutions have a 500 user minimum per month or even having a backup that can be implemented quickly for a school who has the infrastructure but a fire destroys the server rooms.

Another reason i thought it would be good is being low powered it could be run of battery and solar i maybey expecting to much but dont know unless you try

@Shane_Treweek

A lot of people run solar / battery powered Raspberries… I know - for example - of a Bee-Keeper, who has one on each colony, reporting basics via LoRa (Longrange Radio for IoT), powered by sun / batteries. He has 4 colonies in the woods. At home he has the LoRa “Gateway” (Connector between LoRa / TCP/IP / Internet.

See here (Power) for some idea what the market provides:
(From normal power, solar cells, battery regulators & batteries)…

My 2 cents

Hi @Shane_Treweek for lasso: this is my development repo > BE WARNED, not all packages are tested!!

how would i go about installing the nethserver-lemonldap-ng pakage for configuration

17

You should be able to install it from my repo just like you do on x64. It’s a .noarch RPM.

Trying other mirror.

One of the configured repositories failed (DanB35 repository for nethserver 7 - armhfp),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:

 1. Contact the upstream for the repository and get them to fix the problem.

 2. Reconfigure the baseurl/etc. for the repository, to point to a working
    upstream. This is most often useful if you are using a newer
    distribution release than is supported by the repository (and the
    packages for the previous distribution release still work).

 3. Run the command with the repository temporarily disabled
        yum --disablerepo=danb35 ...

 4. Disable the repository permanently, so yum won't use it by default. Yum
    will then just ignore the repository until you permanently enable it
    again or use --enablerepo for temporary usage:

        yum-config-manager --disable danb35
    or
        subscription-manager repos --disable=danb35

 5. Configure the failing repository to be skipped, if it is unavailable.
    Note that yum will try to contact the repo. when it runs most commands,
    so will have to try and fail each time (and thus. yum will be be much
    slower). If it is a very temporary problem though, this is often a nice
    compromise:

        yum-config-manager --save --setopt=danb35.skip_if_unavailable=true

failure: repodata/repomd.xml from danb35: [Errno 256] No more mirrors to try.
https://repo.familybrown.org/nethserver/7/repodata/repomd.xml: [Errno -1] repomd.xml signature could not be verified for danb35

28 
yum clean all
yum --enablerepo=danb35 makecache

and try again?

unfortunatley the same problem i ran

i ended up downloading the rpm and trying manualy

 rpm -i nethserver-lemonldap-ng-0.2.0-6.ns7.noarch.rpm
warning: nethserver-lemonldap-ng-0.2.0-6.ns7.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID 2d55864b: NOKEY
error: Failed dependencies:
	lasso-perl is needed by nethserver-lemonldap-ng-0.2.0-6.ns7.noarch
	lemonldap-ng is needed by nethserver-lemonldap-ng-0.2.0-6.ns7.noarch

so i guess even if i get it working ill need lasso-perl although if thats all not bad out of 200 odd dependencys
