Hi, What is the best way to turn off the iptables?
or come back to its default settings. Flush my current one. Since I tried to configure the iptables, I have encountered the following problems: 1] I can't access the cups and some other ports I opened in localhost. I comment the line 5 still not work. # Allow all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0 4 -A INPUT -i lo -j ACCEPT 5 #-A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT 2] The shutdown process in decades long. I mean it used to be fast to shutdown, now need wait ~3 mins BTW, how to check the time of booting and shutting down? 3] My syslog is flooding with similar information (kernel: [ 436.954509] --log-prefixIN=eth0 OUT= MAC=ff:ff:ff:ff:ff:ff:00:30:67:08:28:b3:08:00 SRC=172.21.50.212 DST=172.21.51.255 LEN=78 TOS=0x00 PREC=0x00 TTL=128 ID=58729 PROTO=UDP SPT=137 DPT=137 LEN=58 ). google showed me it's possible to put the log not in syslog. 4] Are there someone willing to sharing some iptables template, a bit mature one with explaination. Thanks with best regards, P.S. The current one I used ( mainly adopted from http://wiki.debian.org/iptables ), Here it is: 1 *filter 2 3 # Allow all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0 4 -A INPUT -i lo -j ACCEPT 5 #-A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT 6 7 # Accept all established inbound connections 8 -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT 9 10 # Allows all outbound traffic 11 # You could modify this to only allow certain traffic 12 -A OUTPUT -j ACCEPT 13 14 # Allow HTTP and HTTPS connections from anywhere (the normal ports for websites) 15 -A INPUT -p tcp --dport 80 -j ACCEPT 16 -A INPUT -p tcp --dport 443 -j ACCEPT 17 18 # Allow SSH connections 19 #-A INPUT -p tcp --dport 22 -j ACCEPT 20 -A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT 21 22 # Allow ping 23 -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT 24 25 # log iptables denied calls (access via 'dmesg' command) 26 -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level warning 27 28 # Reject all other inbound - default deny unless explicitly allowed policy: 29 -A INPUT -j REJECT 30 -A FORWARD -j REJECT 31 32 COMMIT -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
