Description Lukas Bezdicka 2011-03-03 17:08:28 UTC
SELinux is preventing /usr/libexec/telepathy-haze from 'name_connect' accesses on the tcp_socket port 1900.

*****  Plugin connect_ports (85.9 confidence) suggests  **********************

If you want to allow /usr/libexec/telepathy-haze to connect to network port 1900
Then you need to modify the port type.
Do
# semanage port -a -t PORT_TYPE -p tcp 1900
    where PORT_TYPE is one of the following: mmcc_port_t, sametime_port_t, dns_port_t, http_port_t, msnp_port_t, ldap_port_t, kerberos_port_t, ocsp_port_t.

*****  Plugin catchall_boolean (7.33 confidence) suggests  *******************

If you want to allow the Telepathy connection managers to connect to any generic TCP port.
Then you must tell SELinux about this by enabling the 'telepathy_tcp_connect_generic_network_ports' boolean.
Do
setsebool -P telepathy_tcp_connect_generic_network_ports 1

*****  Plugin catchall_boolean (7.33 confidence) suggests  *******************

If you want to allow system to run with NIS
Then you must tell SELinux about this by enabling the 'allow_ypbind' boolean.
Do
setsebool -P allow_ypbind 1

*****  Plugin catchall (1.35 confidence) suggests  ***************************

If you believe that telepathy-haze should be allowed name_connect access on the port 1900 tcp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep telepathy-haze /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-03-04 10:58:43 UTC
Sounds like we should add a port definition for SSDP port.

Anyway you can allow it using the telepathy_tcp_connect_generic_network_ports boolean.

setsebool -P telepathy_tcp_connect_generic_network_ports 1

Comment 2 Daniel Walsh 2011-03-07 22:25:37 UTC
Miroslav yes lets add that port and allow telepathy domains to connect.

Comment 3 Miroslav Grepl 2011-03-07 22:32:26 UTC
Oops, I thought I added it but obviously no.

Comment 4 Miroslav Grepl 2011-03-07 23:54:31 UTC
Fixed in the next F15 release.
