I have Installed Ebtables on a Fedora Core 4 Machine with Ethernet Bridging enabled. The bridge commands are as:
# ifconfig eth2 0.0.0.0
# ifconfig eth3 0.0.0.0
# brctl addbr test
# brctl addif test eth2
# brctl addif test eth3
# ifconfig test up
The Linux bridge is working fine and I am able to pass the RDP, FTP, ICMP as well as http traffic through this bridge without any problem. The problem is that the ebtables commands which I enter donn seem to work. I have installed Ebtables through source and the commands I entered are:
#ebtables -P FORWARD DROP
#ebtables -A FORWARD -p IPv4 -j ACCEPT
#ebtables -A FORWARD -p ARP -j ACCEPT
#ebtables -A FORWARD -p Length -j ACCEPT
#ebtables -A FORWARD --log-level 1 --log-prefix "EBFW" --log-ip
#ebtables -P INPUT DROP
#ebtables -A INPUT -p IPv4 -j ACCEPT
#ebtables -A INPUT -p ARP -j ACCEPT
#ebtables -A INPUT -p Length -j ACCEPT
#ebtables -A INPUT --log-level 1 --log-prefix "EBFW" --log-ip
#ebtables -P OUTPUT DROP
#ebtables -A OUTPUT -p IPv4 -j ACCEPT
#ebtables -A OUTPUT -p ARP -j ACCEPT
#ebtables -A OUTPUT -p Length -j ACCEPT
#ebtables -A OUTPUT --log-level 1 --log-prefix "EBFW" --log-ip --log-arp -j DROP
The log watcher logs the traffic in syslog, and I am not able to see it. So precisely my questions are:
1- In which file can I see the packets logged by ebtables using the above script? I have checked /var/log/messages and /var/log/dmesg files. There is nothing logged their.
2- I have put all the commands directly on the shell. Do you have to write these commands in some other file?
3- Through the "ebtables-save" script I can see which commands I entered but when I restart the ebtables service all these commands disappear. How can I save my script?
