Re: Limiting Host Access

Could you be more explicit? Depends on what you need to protect exactly. If it's only applications (like the access to your web server, or mail server), this has to be done with acl defined for users and group on the ldap server, and the ability of servers like apache, postfix etc. to authenticate against a LDAP database. Same thing for pam_ldap & nss_ldap (for centralized password management)
If you really want to protect some of your server of any access, you can use netfilter (shipped with linux kernel 2.4) or ipchains (kernel 2.2). (perhaps this a bit definitive!). I'm sure there are a lot of other solutions, but once again it depends of your exact needs.
