You may encounter such a situation:
- "somesite.com" to "192.168.2.3" and then visit "somesite.com"
- 5 minutes later, map "somesite.com" to "192.168.2.4" and then visit it
To change the ip-domain mapping in your machine, you have to edit your hosts file, do some changes, and save it. Frequently doing it may be annoying.
If you are a linux user, you can now make use of dacuoxian to change the mappings with a single shell command.
"dacuoxian(搭错线)", which means "connect false line" in Chinese, is a linux shell script executed by /bin/sh. Make dacuoxian your friend so that you won't connect false lines (I mean not to do false ip-domain mappings, of course)
- download all the files
chmod +x dacuoxian.sh
sudo ./dacuoxian.sh google-hosts-sample
# Note "sudo" may not be available in linux systems other than Ubuntu.- Now check your /etc/hosts file and you can see what's going on
- Then try re-mapping the domains with another group of IPs:
sudo ./dacuoxian.sh google-another-group-of-hosts-sample
. And check your /etc/hosts again. - And you can create your own hosts snippets such as /somepath/foo-hosts1, /somepath/foo-hosts2, /somepath/bar-hosts1 and /somepath/bar-hosts2, and do
sudo ./dacuoxian.sh /somepath/foo-hosts1
#add foo-hosts1 to /etc/hostssudo ./dacuoxian.sh /somepath/bar-hosts1
#add bar-hosts1. Doing this will not remove foo-hosts1 ...- To disable mappings added by dacuoxian, do this:
sudo ./dacuoxian.sh disable google-hosts-sample
You can add some alias so that you can type less:
alias da='cd path-to-your-mapping-files; sudo /path-to-your-dacuoxian-dir/dacuoxian.sh '
alias dad='cd path-to-your-mapping-files; sudo /path-to-your-dacuoxian-dir/dacuoxian.sh disable '
then just
da some-group #enable
dad some-group #disable
```
