Description David Tonhofer 2005-05-06 14:32:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.1) Gecko/20040707

Description of problem:
Update the files /etc/hosts.allow and /etc/hosts.deny with additional hints:

Old:
====

#
# hosts.allow   This file describes the names of the hosts which are
#               allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.
#

Better:
=======

#
# hosts.allow   This file contains access rules which are used to
#               allow or deny connections to network services that
#               either use the tcp_wrappers library or that have been
#               started through a tcp_wrappers-enabled xinetd.
#
#               See 'man 5 hosts_options' and 'man 5 hosts_access'
#                 for information on rule syntax.
#               See 'man tcpd' for information on tcp_wrappers
#

Old:
====

#
# hosts.deny    This file describes the names of the hosts which are
#               *not* allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!

Better:
========

#
# hosts.deny    This file contains access rules which are used to
#               deny connections to network services that either use
#               the tcp_wrappers library or that have been
#               started through a tcp_wrappers-enabled xinetd.
#
#               The rules in this file can also be set up in
#               /etc/hosts.allow with a 'deny' option instead.
#
#               See 'man 5 hosts_options' and 'man 5 hosts_access'
#                 for information on rule syntax.
#               See 'man tcpd' for information on tcp_wrappers
#
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!

Comment 2 John Horne 2006-01-20 13:22:07 UTC
Can I add that the hosts.deny file contains the comment line:

  # The portmap line is redundant, but it is left to remind you that

I have just installed RHEL4 (update 2) and the hosts.deny file contains no
portmap line at all. As such the comment line is confusing. My server has
portmap installed but not nfs, perhaps a portmap line is added only if nfs is
installed?



John.

Comment 5 Tomas Janousek 2007-05-24 11:25:29 UTC
Ouch. The files are not owned by tcp_wrappers at all. Reassigning, clearing
flags, etc. Sorry.

Comment 6 Tomas Janousek 2007-05-24 11:27:17 UTC
Created attachment 155333 [details]
this is the patch for setup in fedora devel

Here's the patch. I think it should go upstream first, though.

Comment 8 Phil Knirsch 2008-02-22 16:36:39 UTC
Suggesting for RHEL-4.8, granting Devel ACK.

Read ya, Phil

Comment 9 Phil Knirsch 2008-02-22 17:05:26 UTC
Still in RHEL-4.7 planing, so reflagging for RHEL-4.7

Read ya, Phil
