* What led up to the situation?
Added 'dhcp-option DNS x.x.x.x' to my openvpn's server.conf but my
Debian client could not get the DNS.
* What exactly did you do (or not do) that was effective (or
ineffective)?
After that I added the lines "up /etc/openvpn/update-resolv-conf' and
'down /etc/openvpn/update-resonv-conf' to my client.conf but it still
did not work.
I expected after this actions my /etc/resolv.conf file to be changed and
have the DNS I had provided in my openvpn's server.conf 'dhcp-option'.
Two, stupid solutions worked for me.
One, I added a second line 'push dhcp-option DNS x.x.x.x' under the
first one and then the script parsed it correctly and all worked as
expected.
Two, I added a '\n' to the script because /etc/resolvconf needs "Each
line in the file must be terminated by a newline".
So when the command
>> echo -n "$R" | /sbin/resolvconf -a "${dev}.openvpn"
executes resolvconf does not parse it correcty as it does not end in a
newline.
For this I changed "$R" to "$R\n" and it worked(on this senario my
server.conf had only one 'push dhcp-option DNS x.x.x.x")
(It also worked and pushed correctly 2 diffrent dhcp-options in this
senario, because I thought that maybe my solution would break adding
more dhcp-option, but it looks like it does not.)
I don't know if adding a "\n" could be a good solution.
Please inform me about the output of this bug report.
Thanks in advance,
Iliana.
