block an ip

block an ip

[yuksel]

Hello,

I'm a novice. I understand how to block acces to some ports but I didn't
understand how to block an ip.

In fact, since 4 days, someone is trying ton hack my network and I have
his ip (he is using more than 10 ip...).

I dont really care cause he is using some funny ways (he thinks that I am
under IIS :) ), but I prefer to stop him now.

Friendly,
Yuksel.

Block an IP

[Cory McPherson]

Hello,

I'm new to iptables and would like to block an IP. How do I achieve that? More specifically, I'd like to block it from accessing a specific port
but other ports should be accessible to that IP... Can someone give me an example?

Thanks

PS: please CC me as I'm not subscribed to the list.

Assuming your protocal is tcp:

iptables -A INPUT p- tcp --source <IP Address> --dport <Port No.> -j REJECT
