Subject: Re: sysctl, argument parsing, possible bug
I make another test with kernel 4.9.32-15.41
sysctl procps version 3.2.8
sysctl net.ipv4.conf.eth0.100.forwarding
error: "net.ipv4.conf.eth0.100.forwarding" is an unknown key
so I install busybox :
BusyBox v1.19.3
busybox sysctl net.ipv4.conf.eth0.100.forwarding
net.ipv4.conf.eth0.100.forwarding = 0
It is working, as I expect reading busybox source sysctl.c
Stephen, I test
sysctl net/ipv4/conf/eth0.100/forwarding
I confirm it works.
What is the problem ?
As sysctl, also automation tools and scripts cannot be "netdev names
aware", and so they fail using the usual dot notation.
I don't pretend to change sysctl to read from the /proc/sys/
directory, as busybox does.
I suggest to add a remark to the man page of sysctl, reporting the
difference between the two tools and an example of the alternate
syntax :
sysctl net/ipv4/conf/eth0.100/forwarding
Thank you for your attention.
Best regards, Massimo
