Well, the traditional trick is to watch the firewall log to see what it rejects from the machine of interest and open it.
well, there is the first problem. I do not find any log file from firewall. There is in /var/log firewalld but it does not seem to hold logs from firewall.
You might have to tell the firewall to log things. I don't have firewalld in this machine, so I can not look up for you where it is done.
It repeats:

So apparently the system is not writable??? Maybe I am not using firewalld? I am lost sorry. What else logs I have to look at?
Did you say TW? Maybe in TW the /etc path is RO. Or the firewall runs too early. No idea. -- Cheers / Saludos, Carlos E. R. (from 15.3 x86_64 at Telcontar)
