I'm using Arch Linux and I have a dynamic ip address with the use of dhcpcd. I can access websites through the google chrome but the problem is that I get 'could not resolve host' error when I run some commands on the terminal (like git clone).

I've tried pinging github.com and doing nslookup and it returns the correct ip. Any ideas?

  • have you tried this? – Nico Boni Apr 7 '13 at 6:01
  • @dcmst Cool, works fine now. You should post that as an answer. Thanks! – gerky Apr 7 '13 at 6:15

Problem is that sometimes dhcpcdor other processes overwrite the content of the resolv.conf file, which is where DNS library resolver configuration is stored, inserting the DNS servers from your internet service provider, which may not work in some cases.

In case of problems it may be a good idea to change the content of resolv.conf to point to Open DNS servers (which should work better than your service provider servers):

# OpenDNS servers


# Google nameservers

and then protect the content of resolv.conf from dhcpcd adding the line nohook resolv.conf to /etc/dhcpcd.conf See the mighty Arch wiki for more details

  • @beefjerky, you're welcome, maybe this was actually caused by the same DNS problem? – Nico Boni Apr 8 '13 at 14:09
  • Yup, it was the same issue. I'm closing it. – gerky Apr 10 '13 at 13:23
