http://www.unix.com – Hi, I want to add a search domain name in the beginning of /etc/resolv.conf. If already some '#' symbols are there in the beginning I want to add it below # the search domain which I want to add, the example search domain is "search xxxx.com" So the resolv.conf should be as shown below cat /etc/resolv.conf #domain name entries search xxxx.com 1.2.1.33 aaaaa aaaa.com 1.2.3.22 mmm mmm.com So I want to add the word "search xxxx.com" in the beginning /etc/resolv.conf I tried Code: sed s/.*$/& search xxx.com/ /etc/resolv.conf But this one expects me to create (HowTos)

My /etc/resolv.conf shows:

# Generated by NetworkManager domain someuniversity.ac.uk search someuniversity.ac.uk nameserver 128.85.161.265 nameserver 128.85.161.241

I understand nameserver but what is the usefulness and relevance of "domain" and "search"?

Thanks .

I have set up my own bind9 DNS server and put into my /etc/resolv.conf

nameserver 127.0.0.1 domain mydomain.local

and put the same content into /etc/resolvconf/resolv.conf.d/head

still the dns fails once in a while and additional information (the ones from my hoster) are magically written into the etc/resolv.conf. Am I missing any service how manages this file and conflicts with bind9?

Issue on resolv.conf 18 weeks 2 days ago

Hi all, :(

I am facing issue while I have updated in resolv.conf, after nework service restart, it was automatically deleted IP from resolv.conf file. Could you please let me know what is the reason resolv.conf deleted any IP which I have manually updated, but it store only my router IP permanently.

Advance thanks for helping..

The resolv.conf supports a line called options that allows for some fine tuning of the behavior of the resolver. In my environment we are using ISC's DHCPD to provide DHCP services to our services.

This might be the right forum, or not.

Old stock DNS (nslookup, dig, ssh) etc would attempt to use each of the domains listed in the search list (/etc/resolv.conf) to find a given target given a base_name (w/out a ".")

The current configuration uses 127.0.0.1 as a caching server and relies on dnsmasq to lookup dns entries from upstream providers. DNSmasq as driven by NetworkManag

My /etc/resolv.conf constantly get a mysterious entry, i run a home network with ipv6 provided by ravd, the interface is auto-configured by Network manager (all name server lookups are lost when this line is first in my /etc/resolv.conf) .

Hello, im running server 12.4 LTS on an old pc. I can get the static ip working after i add the "nameserver xxx.xxx.xxx.xxx" to /etc/resolv.conf But after a reboot my resolv.conf file is over written and my internet connecgion does not work. I can still ssh to it, change the resolv.conf file and restart my interfaces but id rather it work from boot up.

I have Gentoo Linux amd64 installed on one of my computers. I have a static IP configured at /etc/conf.d/net:

auto_eth0="true" config_eth0="192.168.1.2/24" routes_eth0="default via 192.168.1.1" enable_ipv6_eth0="false"

I manually edited /etc/resolv.conf and added google dns servers. the problem is that whenever I restart my server /etc/resolv.conf gets wiped out.
