I have been using SAMBA to share files on my HTPC and it worked fine until now. I haven't touched the HTPC in over a month and today the sharing suddenly stopped working by itself.
I traced the problem down to iptables. Currently I use this set of rules and up until now the samba worked flawlessly:
~$ sudo iptables -L -v
Chain INPUT (policy DROP 61 packets, 4786 bytes)
pkts bytes target prot opt in out source destination
102 6843 ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:ssh
0 0 ACCEPT udp -- any any anywhere anywhere udp dpt:ssh
0 0 ACCEPT all -- lo any anywhere anywhere /* This allows all traffic on localhost. */
0 0 ACCEPT udp -- enp4s2 any anywhere anywhere udp dpt:netbios-ns /* Samba LAN */
0 0 ACCEPT udp -- enp4s2 any anywhere anywhere udp dpt:netbios-dgm /* Samba LAN */
0 0 ACCEPT tcp -- enp4s2 any anywhere anywhere tcp dpt:netbios-ssn /* Samba LAN */
0 0 ACCEPT tcp -- enp4s2 any anywhere anywhere tcp dpt:microsoft-ds /* Samba LAN */
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http
Chain FORWARD (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 80 packets, 11372 bytes)
pkts bytes target prot opt in out source destination
I have managed to get the samba working by changing Chain INPUT (policy DROP) to Chain INPUT (policy ACCEPT), but obviously this is just a temporary fix, since I don't want the htpc to just accept any suspicious incoming traffic.
Any idea why it stopped working all the sudden?
Thanks
