<SOLVED>unable to make network setting stick

[BruceKaufman]

I have a new mint 17 installed. I ran the Network Manager and it updated /etc/NetworkManager/system-connections/Ethernet connection1:
[802-3-ethernet]
duplex=full
mac-address=<looks ok>
[connection]
id=Ethernet connection 1
uuid=<looks good>
type=802-3-ethernet

[ipv6]
method=auto

[ipv4]
method=auto
dns=192.168.0.1;
may-fail=false

waited, no internet, rebooted, no internet

Modified /etc/resolve.conf and added nameserver 192.168.0.1

and internet now works. Of course on reboot, this file is overwritten.

Suggestions?

FYI:

sudo lshw -c network -sanitize

Hello, BruceKaufman.

For several Linux Mint versions now the file /etc/resolv.conf by default is merely a symbolic link to /var/run/resolvconf/resolv.conf. Neither (link) file should be modified manually.
Instead write your additional nameserver entries into the file /etc/resolvconf/resolv.conf.d/tail.
And maybe you would like to read

Code: Select all

man resolvconf

for further details.

Kind regards,
Karl

Thank you!! Adding a nameserver line to the /etc/resolvconf/resolv.conf.d/tail fixed the problem.

On a side note: Shouldn't the "network connection" manager tool (the one so many people on the web seem to tout as the way to set the nameserver) update resolv.conf.d/tail file? Or am I misunderstanding what this tool can do?

Also I read the resolvconf page but I guess the note was too cryptic for me

Hello, BruceKaufman.

The file /etc/resolvconf/resolv.conf.d/tail is explicitly meant for entries which the user adds and which will not be overwritten by the network manager dynamically at runtime.

Cheers,
Karl
