sepolicy-communicate(8)

NAME
sepolicy-communicate - Generate a report showing if two SELinux Policy Domains can communicate

SYNOPSIS
sepolicy communicate [-h] -s SOURCE -t TARGET [-c TCLASS] [-S SOURCEACCESS] [-T TARGETACCESS]

DESCRIPTION
Use sepolicy communicate to examine SELinux Policy and determine if a source SELinux Domain can communicate with a target SELinux Domain. The default command looks to see if there are any file types that the source domain can write, which the target domain can read.

OPTIONS

-c, --class
    Specify the SELinux class which the source domain will attempt to communicate with the target domain. (Default file)

-h, --help
    Display help message

-s, --source
    Specify the source SELinux domain type.

-S, --sourceaccess
    Specify the list of accesses used by the source SELinux domain type to communicate with the target domain. Default Open, Write.

-t, --target
    Specify the target SELinux domain type.

-T, --targetaccess
    Specify the list of accesses used by the target SELinux domain type to receive communications from the source domain. Default Open, Read.

EXAMPLE
List types that can be used to communicate between samba daemon and apache server
# sepolicy communicate -s httpd_t -t smbd_t
Consider a type to be accessible by the source domain when it can be opened and appended to (as opposed to opened and written to)
# sepolicy communicate -s httpd_t -t smbd_t -S open,append
