Hi,
I have set monitor-connection-files=true in my
/etc/NetworkManager/NetworkManager.conf
It works fine (in fact, instantly) if I edit
/etc/sysconfig/network-scripts/ifcfg-eth0 with emacs or vi (for instance,
changing the IP).
It fails miserably if I use sudoedit, or sed:
I *think* emacs writes a new file with a different name and then renames
it.
Try "ls -li /etc/sysconfig/network-scripts/ifcfg-eth0" before and after
editting; if the inode/inum (the number at the beginning) has changed
that is what your editor is doing, and what NetworkManager is looking for.
# grep 100 /etc/sysconfig/network-scripts/ifcfg-eth0
IPADDR=192.168.4.100
# sed -i 's/100/155/g' /etc/sysconfig/network-scripts/ifcfg-eth0
Even though all stats (access modify and change) are renewed.
It's worse than that: even nmcli con reload afterwards fails.
In fact, the only way to get the ip to change is by entering the file with vi, not touching it, and
leave with ":wq" (not just ":q").
Why is that? What is going on here?
I know, I know, I can use nmcli in scripts, and not string-manipulation tools,
but say I don't want to... :)
And still, during operations, I'd rather edit the files with sudoedit...
Thanks in advance,
