File format of nsswitch.con

[Cai Nan]

Hi,every one.
In /etc/nsswitch.conf:
hosts:dns[NOTFOUND=continue UNAVAIL=continue TRYAGAIN=continue] files[NOTFOUND=return UNAVVAIL=continue TRYAGAIN=return]
What this mean,and which option could be changed?
Thanks!

Hi,

All the values can be changed depending on your requirements.

Status Meaning
SUCCESS Requested database entry was found
UNAVAIL Source is not responding or corrupted
NOTFOUND Source responded "no such entry"
TRYAGAIN Source is busy, might respond to retries

In your configuration of /etc/nsswitch.conf, the DNS is used before /etc/hosts is used for name resolution.

man 1m nsswitch.conf for more information.

Hope this helps. Regards.

Hi,

It is better to have the file option first.
If your DNS is down there will be a timeout
before it check the local hosts file. Try
changing the order to this:

hosts: files [NOTFOUND=continue UNAVAIL=return TRYAGAIN=return] dns [NOTFO
UND=return UNAVAIL=continue TRYAGAIN=return]
