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

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.

-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.

# sepolicy communicate -s httpd_t -t smbd_t

# sepolicy communicate -s httpd_t -t smbd_t -S open,append
