should this port be open!
 

Hey all,

Silly question here!
Smoothwall version1.0 -
I dont have a web server but for some reason port 80 is opened on my firewall. If it should be blocked would the command be?

Thanks all in advance.

you might have apache installed and running; remove apache
and the port will not be held open by anything.

Yes apache is running for the web administration from which It is configured to listen to port 445. I am just unsure why it would be still open if its not listening to port 80 anymore.

I am finding the IPCHAINS command a little difficult.
I have read a HOW TO on the command but I dont want to kill my web browsing.

Thanks for getting back to me. :D

hmm.. you could use iptables to close that port;

/sbin/iptables -A INPUT -p tcp --syn --destination-port 80 -j DROP

port 445 will then stay unaffected.

incase this is not what you want, you can remove this rule by doing:

/sbin/iptables -D INPUT -p tcp --syn --destination-port 80 -j DROP

good luck.

Actually my firewall uses ipchains. I tried to modify the command you gave me but it didnt work (replied back no target). I am using smoothwall 1.0. Have you tried the Mandrake Network Firewall yet? I am interested in moving to it. It uses iptables. It seems the packages are more current than smoothwall. I do know that when smoothwall 2.0 comes out it has changed to iptables. So whats the difference. According to a website I looked up iptables does stateful packet inspection. I thought ipchains did that also.

Once again thanks for getting back to me.

which one do you have iptables or ipchains iptables is the never one that comes with 2.4.x kernels

Im running ipchains. I have a 2.2.X Kernel.
