Description Daniel Tröder

2017-03-31 11:49:28 CEST

Sometimes (not easily reproducible) after an upgrade UCS 4.1->4.2, all new incoming connections - incl SSH and HTTP(S) ! - are blocked. A restart of the univention-firewall fixes that then (as does a server reboot).

Add "systemctl restart univention-firewall.service" to postup.sh to make sure the system is accessible after an upgrade.
