+====== Remove a host that denyhosts has banned ======
+**Denyhosts** is a utility that automatically bans IPs who attempt to ssh in to your server and get three wrong passwords.
+This is great when people are dictionary-attacking your **SSH server**, but less good when you have actual users who might get their //password wrong//.
+<code>
+#/bin/sh
+REMOVE=$1
+service denyhosts stop
+cd /var/lib/denyhosts
+for THISFILE in hosts hosts-restricted hosts-root hosts-valid users-hosts;
+do
+mv $THISFILE /tmp/;cat /tmp/$THISFILE | grep -v $REMOVE > $THISFILE;rm /tmp/$THISFILE;
+done
+mv /etc/hosts.deny /tmp/
+cat /tmp/hosts.deny | grep -v $REMOVE > /etc/hosts.deny;
+rm /tmp/hosts.deny
+service denyhosts start
+</code>
+Needs to run as //root//.
