De-install webproxy(squid)

Bug
, , ,
#1

NethServer Version: NS7RC3
Module: webproxy

I am having some issues with an Android application that is used for my kids’ school. It is the application for the schools student management environment. As a parent I have my own account there and get informed through the application about grades and homework of my kids.

Since a few days this application seems not to connect anymore. I am not 100% sure but the problems started when I reinstalled webproxy module after the fix with the samba shares permissions.

Now when I go to software center and select web proxy to be removed I get a list of dependencies that also get removed. Some of those I ask myself: WHY are they dependencies for the web proxy?

Confirm system changes

Modules to remove:

    nethserver-web-proxy

Packages to remove:

    nethserver-httpd
    nethserver-lightsquid
    nethserver-squid
    nethserver-bandwidthd
    nethserver-cgp
    nethserver-nextcloud
    nethserver-samba-audit
    nethserver-squidclamav
    nethserver-squidguard

Samba-audit package? httpd package? Nextcloud? WHY?

PS: After de-install of the webproxy the application worked normal again. I guess it can’t deal with a proxy, or the proxy can’t deal with the application. (I would love to know how to configure the proxy so I can allow the application to pass without going through the proxy.)

Software removal is a big problem: in our enterprise release we had to hide the “Remove” button to lower the number of support ticket. :frowning:

Here you have a full description of the problem:

If you know the host contacted by the application, you could add a list of non-proxied sited.

The problem could be nethserver-httpd set as mandatory in Web Proxy group. Isn’t it superfluous? /cc @giacomo

#4

No it’s not. Apache is used to server the wpad file.

I guess lightsquid depends on httpd: isn’t it enough to serve wpad.dat to LAN?

Is nethserver-httpd really required?

Only “leaf” packages should be marked “mandatory” in group definitions to avoid cascade/recursive removals like this.

#6

No. Lightsquid uses httpd to display the graphs.
Squid uses httpd to serve the wpad.

Again, yes. We need to open the firewall port and make sure the service is running.

#7

So why not adding an RPM dependency to nethserver-httpd in nethserver-squid and remove the “mandatory” in group? It is a functional dependency, not a group one!

The httpd module wasn’t even the biggest issue. Removing Nextcloud was much more invasive and you can potentially loose data if you re-install Nextcloud and the previous database gets dropped.

#9

I’m not sure: nethserver-squid works even without nethserver-httpd but lacks of a feature.

I don’t know if it’s correct to use the RPM dependency, but in this case this choice could probably fix Rob problem.

It already has one :blush:

Just updated YUM group compositions. This commit fixes also nethserver-web group:

@robb, please wait until all repository mirrors are synced with the change above to test the fix.
