Error when starting dockers in GNS3 in Opensuse TW

[jsaenz01]

Hello,
A few months ago the dockers in GNS3 worked perfectly on my PC.
Now, they refuse to start.

I don't know if it was an update, a new dependency, my fault,... The truth is that I updated from Opensuse 15.5 to Tumbleweed.

I get "--install: applet not found
sh: invalid number '0.5'" in every docker I try.

I also add the complete gns3server log in case you can help, thank you.

I can do all the tests you need.

Thank you.

Hi again,

I have just done more tests. Dockers works in 2.2.47 versión, but it fails in laters.

I don't know if is related, but Dockers dont get a ip en dhcp

Do you have any busybox or busybox-static package installed?

If yes, what is the result of the following commands?

$ whereis busybox
busybox: /usr/bin/busybox /usr/share/man/man1/busybox.1.gz
$ busybox | head -1
BusyBox v1.30.1 (Ubuntu 1:1.30.1-7ubuntu3.1) multi-call binary.

Thanks 👍

[jsaenz01]

I have both installed .This is the information you asked:

[grossmj]

Thanks, I also need the output of the following commands please:

ldd /usr/bin/busybox
ldd /usr/share/busybox
ls -l ~/.local/share/GNS3/docker/bin/
ldd ~/.local/share/GNS3/docker/bin/busybox
busybox sleep 0.5

Hi,
Here It's

Last one:

[grossmj]

Ok, I think I understand the problem now.

Please can you edit ~/.local/share/GNS3/docker/init.sh and replace sleep 0.5 by sleep 1?

Let me know if this solves the issue. Thanks.

Hello,
Now the dockers start!! Thanks for your quick response.

However, Docker does not obtain an IP automatically. I don't know if it's related or not, or if it's a bug in the templates. Just in case:

The config is in DHCP:
`#

This is a sample network config, please uncomment lines to configure the network

Uncomment this line to load custom interface files

source /etc/network/interfaces.d/*

Static config for eth0

#auto eth0
#iface eth0 inet static

address 192.168.0.2

netmask 255.255.255.0

gateway 192.168.0.1

up echo nameserver 192.168.0.1 > /etc/resolv.conf

DHCP config for eth0

auto eth0
iface eth0 inet dhcp

hostname UbuntuDockerGuest-1**

`

Thanks!!!!!

[grossmj]

Hum strange. What if you execute the init.sh script from the container? /gns3/init.sh

Also, can you share your busybox executable ~/.local/share/GNS3/docker/bin/busybox by attaching it here? (maybe you will have to zip it first to pass restrictions),

[jsaenz01]

Hi,
Problem is that there is no Ifup command

However:

The file is here

busybox.zip

Thanks!

[jsaenz01]

Hi again,

I manually replace this file with busybox-static from Ububuntu 24.04LTS. Now Its working again.... I can do any test you need.

Thanks again!!!

[grossmj]

Yes, somehow some things don't work well with the BusyBox static shipped with Tumbleweed ;)

[grossmj]

I found the reason.

The busybox v1.36.1 shipped in Opensuse TW does not have the --install parameter anymore.

$ busybox
BusyBox v1.36.1 () multi-call binary.
BusyBox is copyrighted by many authors between 1998-2015.
Licensed under GPLv2. See source distribution for detailed
copyright notices.

Usage: busybox [function [arguments]...]
   or: busybox --list
   or: function [arguments]..

While busybox v1.30.1 shipped in Ubuntu has it.

$ busybox 
BusyBox v1.30.1 (Ubuntu 1:1.30.1-7ubuntu3) multi-call binary.
BusyBox is copyrighted by many authors between 1998-2015.
Licensed under GPLv2. See source distribution for detailed
copyright notices.

Usage: busybox [function [arguments]...]
   or: busybox --list[-full]
   or: busybox --install [-s] [DIR]
   or: function [arguments]...

In our init.sh script, we use this --install parameter to create symlinks to busybox commands: https://github.com/GNS3/gns3-server/blob/master/gns3server/compute/docker/resources/init.sh#L25L29

The script then cannot find commands like ifup or ipsince the symlinks could not be installed.
