are /etc/hosts.allow and /etc/hosts.deny used by sshd ?

[Jdamian]

Hi

Man pages of sshd(8) says:

/etc/hosts.allow, /etc/hosts.deny
Access controls that should be enforced by tcp-wrappers are defined here. Further details are described in hosts_access(5).

My problem is the referred manual pages in volume 5 don't exist.

Can anybody explain me something about this config files ?

Heres the manpage for hosts_access;

If ssh is the one provided by HP, then it has tcp wrappers build in. So file /etc/hosts.allow and /etc/hosts.deny will be checked.

For testing it create a file /etc/hosts.deny and put entry deny:ALL in it and try ssh to this server.

If you have compiled your ssh, may be open ssh, then it depends did you compile it with tcp wrapper or not.
