There is ticket in trac to impement it.
You can use netstat utility for such purpose as a workaround. For demonstaration putposes I send signals to main sssd process to go offline and then online. And you need to run netstat as a root otherwise you will not see PID and name of sssd process (netstat -p) [root@host ~]# netstat -tpn | grep sssd_be tcp 0 0 10.34.129.86:56053 10.16.78.114:389 ESTABLISHED 7265/sssd_be [root@host ~]# kill -USR1 `pgrep sssd$` [root@host ~]# netstat -tpn | grep sssd_be [root@host ~]# kill -USR2 `pgrep sssd$` [root@host ~]# netstat -tpn | grep sssd_be tcp 0 1 10.34.129.86:56055 10.16.78.114:389 SYN_SENT 7265/sssd_be [root@host ~]# netstat -tpn | grep sssd_be tcp 0 0 10.34.129.86:56055 10.16.78.114:389 ESTABLISHED 7265/sssd_be HTH LS _______________________________________________ sssd-users mailing list [email protected] https://lists.fedorahosted.org/mailman/listinfo/sssd-users
