filedist.block

NAME

SYNOPSIS

AVAILABILITY

DESCRIPTION

FILEFORMAT

mode:source_host:destination_host:file

The mode field specifies if a rule is to allow or block a file being distributed from a source- to a destination host.

The fields source_host, destination_host and file are regular expressions.

The rules are processed in the sequence listed. If a rule matches, the remaining rules are not processed any more.

The last rule that is processed by filedist is always

  block:.*:.*:.*

  allow:.*:.*:.*

Regular expression hints:

.*

Everything. This can be used to specify all hosts or all files.

dcdbsi5[1-3]

Range. This example defines the hosts dcdbsi51, dcdbsi52 and dcdbsi53.

See also EXAMPLES section.

OPTIONS

mode

mode to define the rules what files can be distributed:

allow

if the rule definition of source_host, destination_host and file matches, the file is allowed to be distributed.

block

if the rule definition of source_host, destination_host and file matches, the file is blocked from distribution.

source_host

Regular expression of the source host. The source host to be dealt with is as it is resolved by the hostname(1) command.

destination_host

Regular expression of the source host. The destination host to be dealt with is as it is specified in the interactive "Target hosts:" query of the filedist command. When specifying the destination_host take also into account, that the user could specify aliases for distribution targets or use a full qualified name. In most cases it wouldn't be needed to specify all aliases due to the provided default targets that should lead the user into the right direction.

file

Regular expression of the file to be distributed.

EXAMPLES

1) block rule example

This definition helps, that only files in the directories /opt/edrc, the installation directory of WA2L/edrc, and /tmp are allowed to be distributed from and to dcdbsi50.

This example has the background, that the host dcdbsi50 is a Sun Solaris system and all other hosts are HP-UX systems. To avoid miss-configuration of the systems by distributing operating system files that might have a different format on either one of the two operating systems, only a very reduced set of files is allowed to be distributed.

The last rule in this example ensures, that between all other systems all files are allowed to be distributed.
