Description of problem: by default firestarter blocks avahi multicast (mDNS) and it's not possible to anable it via tue gui. You need to modify /etc/firestarter/user-pre and add : $IPT -A INPUT -s 224.0.0.0/8 -d 0/0 -j ACCEPT $IPT -A INPUT -s 0/0 -d 224.0.0.0/8 -j ACCEPT $IPT -A OUTPUT -s 224.0.0.0/8 -d 0/0 -j ACCEPT $IPT -A OUTPUT -s 0/0 -d 224.0.0.0/8 -j ACCEPT or remove $IPT -A INPUT -s 224.0.0.0/8 -d 0/0 -j DROP $IPT -A INPUT -s 0/0 -d 224.0.0.0/8 -j DROP $IPT -A OUTPUT -s 224.0.0.0/8 -d 0/0 -j DROP $IPT -A OUTPUT -s 0/0 -d 224.0.0.0/8 -j DROP from the firestarter script As avahi-daemon is enabled by default, firestarter should authorize multicast by default or at least being able to authorize it by gui. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. enable firestarter 2. launch avahi-discover-standalone 3. Actual results: avahi-discover-standalone is not able to scan mDNS services Expected results: avahi-discover-standalone is able to scan mDNS services and find at least workstation. Additional info:
This should be fixed in the next round of updates.
for me its not fixed firestarter-1.0.3-11.fc5 I still need $IPT -A INPUT -s 224.0.0.0/8 -d 0/0 -j ACCEPT $IPT -A INPUT -s 0/0 -d 224.0.0.0/8 -j ACCEPT $IPT -A OUTPUT -s 224.0.0.0/8 -d 0/0 -j ACCEPT $IPT -A OUTPUT -s 0/0 -d 224.0.0.0/8 -j ACCEPT in user-pre
The user-pre file is generated by firestarter and is a configuration file. If it was generated by a previous install of firestarter, you probably need to manually remove the $IPT -A INPUT -s 224.0.0.0/8 -d 0/0 -j DROP $IPT -A INPUT -s 0/0 -d 224.0.0.0/8 -j DROP $IPT -A OUTPUT -s 224.0.0.0/8 -d 0/0 -j DROP $IPT -A OUTPUT -s 0/0 -d 224.0.0.0/8 -j DROP statements from it.
