I am new to GCP services and try to deploy mininet-wifi script to the cloud. On physical machines the installation described in the link and the SDN python script work pretty fine. However, for some reason on GCP Ubuntu instance this does not happen.
When I run the python script I get this error:
modprobe: FATAL: Module mac80211_hwsim not found in directory /lib/modules/4.13.0-1006-gcp
find: ‘/sys/kernel/debug/ieee80211’: No such file or directory
Warning! Error when loading mac80211_hwsim. Please run sudo 'mn -c' before running your code.
During the installation no errors regarding the module were displayed. I tried to add manually but are not avaiable:
# modprobe mac80211_hwsim
modprobe: FATAL: Module mac80211_hwsim not found in directory /lib/modules/4.13.0-1006-gcp
# modprobe mac80211
modprobe: FATAL: Module mac80211 not found in directory /lib/modules/4.13.0-1006-gcp
I find difficulties to find some working/updated manual to build these modules by hand. Do you know if GCP allows to build and add new modules to the kernel ?
