I am running OpenVPN client as daemon mode on my Laptop running Ubuntu Desktop Linux OS 10.04. *The issue which i am facing is that the DNS is not being populated to */etc/resolv.conf.*
I see push "dhcp-option DOMAIN ..." in OpenVPN Server configs., I have added the push "dhcp-option DOMAIN ..." in my client config. but no luck.
Works perfectly fine for Windows Client. Not sure why it does not work for Linux Clients.
Please suggest/guide
Thanks

Installed resolvconf and put known good DNS servers in the head file.
On my workstation, I finally just had it, and set it to what I wanted it

Hi W. Scott Lockwood III
Head file ? which file are you referring to ? I did installed resolvconf on Ubuntu 10.04 desktop
On my workstation, I finally just had it, and set it to what I wanted it
to be all the time, and did 'sudo chattr +i /etc/resolv.conf' on it.

You really should 'man resolvconf' before asking such basic questions.

Hi Again
Let me explain in details the issue as i am facing now
I have three Internet Service Provider to connect to internet from my laptop running Ubuntu Desktop Linux OS 10.04*
For example ISP A, ISP B ISP C
ISP A *--> is the Office Network (when i am in office )ISP B --> *is the Mobile Broadband Network (when i am moving )
ISP C --> is the Home Network (when i am at home)
Also in addition to the above details :-*
I have local DNS Server at office, DNS server of Data Center 1 and DNS Server of Data Center 2. so whenever i am in office, by default i need to connect to these*
three DNS Servers in order to access the servers.
The steps i have followed after using resolvconf
sudo apt-get install resolvconfsudo rm /etc/resolv.conf
sudo ln -s /etc/resolvconf/run/resolv.conf /etc/resolv.confsudo vim /etc/openvpn/update-resolv-conf*Add the following lines in the beginning.*foreign_option_1='dhcp-option DOMAIN off.example.com dc1.example.com dc2.example.com'
foreign_option_2='dhcp-option DNS 172.26.0.1'foreign_option_3='dhcp-option DNS 10.20.0.1'foreign_option_4='dhcp-option DNS 10.20.0.2'foreign_option_5='dhcp-option DNS 10.30.0.1'
save and exit
Add the below two lines at the bottom of the file openvpn client DC1.conf*up /etc/openvpn/update-resolv-confdown /etc/openvpn/update-resolv-conf
The issue which i am facing is that I am unable to resolve the local DNS Servers at office. I need the local DNS Server in order to access Network printers*and other devices.
Office DNS Server is off.example.com and DNS Server IP is*172.26.0.1
How do i go about in fixing this issue.
Please suggest/guide
Thanks and Regards
Kaushal

Are all five options above for your office network?
Please post "cat /etc/resolv.conf" after you connect to your office network.

Hi Tom,*
Are all five options above for your office network?
Not sure i understand that ?**
Please post "cat /etc/resolv.conf" after you connect to your office network.
cat /etc/resolv.conf in my Ubuntu Laptop Desktop PC running 10.04
search**off.example.com**### office
search*dc1.example.com*### DataCenter No.1*search*dc2.example.com' ### DataCenter No. 2
DNS 172.26.0.1
DNS 10.20.0.1
DNS 10.20.0.2
DNS 10.30.0.1
Please suggest further
Thanks

This "resolv.conf" is incorrect.
The "DNS" lines don't mean anything. It shouldn't be "DNS" but "nameserver".
The "search" lines don't make sense (although I could be wrong). I
don't use "search" but I'd expect your "resolv.conf" to have one
search line "search example.com" with your domain and not three with
boxes.
(I'd asked whether the five "foreign_option_X" were for your three
locations or just for your office.)
