Is there a way to flush the DNS cache?

Is there a way to flush the DNS cache on a Debian Stable machine?

The reason is, I had a domain name put in /etc/hosts but I just recently
taken it out to fix things. Only thing is, the system still thinks the
domain name is the local machine even though it's a DNS for my external
network. I even tried a reboot. Same thing.

Reboot should be enough, and so you should have another problem.

Give more information :

- /etc/hosts
- /etc/resolv.conf
- bind configuration if any (/etc/bind/named.conf)
- ...

This is /etc/hosts:

127.0.0.1 DebianServer localhost DebianServer.ZeroOneNetworks
192.168.1.101 DebianServer.ZeroOneNetworks DebianServer

# The following lines are desirable for IPv6 capable hosts
# (added automatically by netbase upgrade)

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

This is /etc/resolv.conf:

nameserver 192.168.1.1
nameserver 207.255.0.135
nameserver 207.255.0.136


I used to have bind but uninstalled it.

Weird thing though. I don't normally put in 192.168.1.1 in my /etc/hosts
but I tried it for the heck of it. Oddly enough once I put in
192.168.1.101 into the /etc/hosts, everything is back to normally. The
very strange part? 192.168.1.1 uses the exact same DNSes, listed in
/etc/resolv.conf. Really weird DNS issue?

Should be:
127.0.0.1 localhost

Also one other error, after a reboot, /etc/resolv.conf is just a blank file.

Hi!! Try 'rndc flush'!!
