Upon the install of BigBlueBotton in Debian 9, I run the script bbb-conf --check to make consistency checks of the setup. (bbb-conf is a configuration/setup tool to BBB)
The script return me in all consistency checks the address of the machine as inet. What is happening?
I have found out why bbb-conf is not seeing the IP address correctly.
bbb-conf is a bash script that runs the ifconfig command.
The cause is that the output/fields of the ifconfig output changed in Debian version 9.
Thus, the regexps in the script no longer give a match to the current address.
In Debian 8/Jessie:
inet addr:193.136.188.36 Bcast:193.136.188.255 Mask:255.255.255.0
In Debian 9/Stretch:
inet 10.23.20.19 netmask 255.255.255.0 broadcast 10.23.20.255
Is it recommend to change the script to ip addr show as ifconfig is being deprecated, and the output of ip does not change across versions.
So instead of:
ifconfig | grep -v '127.0.0.1' | grep -E "[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*" | tail -1 | cut -d: -f2 | awk '{ print $1}'
change it to:
ip addr show | grep inet | tail -1 | awk ' { print $2 } '
After changing/correcting the offending lines, the script already shows the IP address correctly, however now it spews as warnings, that the IP addresses in the configuration files are incorrect. The post-installation scripts also inserts inet instead of the correct address due to unfortunate changes to the ifconfig output format in Debian.
