Kathar Critical Error

[lukes1582]

Hi, after installing docker-ce and following the "kathara" installation procedure, I checked. This is what generated the check. Can you help me???

Hi @lukes1582, I can see two errors in the katahra check output:

1. /bin/sh: 1: /sbin/iptables: not found For this, we're not sure of the cause, so please type kathara settings and set the logging level to EXCEPTION. Then, run kathara check and paste here the stacktrace output.

2. CRITICAL - [Errno 2] No such file or directory: '/usr/lib/kathara/python3' We already know this bug and we'll fix it in the next release. However, despite this, kathara should works fine.

Please, let us know if you have problems.

Thanks.

Hi @tcaiazzi , I made the changes you told me. This is the result

I will try kathara functioning. If there are other errors I will report them to you. Have you ever thought about developing a simple gui? It might be useful to show all networks!

[tcaiazzi]

Hi @lukes1582,

If you want a gui you can use the Netkit-Lab-Generator. It's a tool to configure the networks and generate all the configuration files.

Thanks.

Hi @lukes1582, new release 3.0.6 fixes the check problem. About /bin/sh: 1: /sbin/iptables: not found, it is not a Kathará-related issue and you should verify that iptables is correctly installed into your OS.

Thanks, Mariano.

[lukes1582]

Hi @Skazzino thanks for the information. Today I have updated the software and the critical error is not present. @tcaiazzi I see the Netkit-Lab-Generator... I am reviewing the javascript code and I have also modify the images (they weren't beautiful).
