Hello,
I am trying to find out if there is an IP being block/listed in iptables and if so, how to remove it.
What is the command line to
1) to see if a IP is being blocked
and
2) the command to remove the IP being block, is listed
the last time I messed with Iptables, the server locked up on me and had to request a reboot, so wanted to make sure I am using the correct command line options.
TIA,
Mickalo
Full Version: Iptables commands help
Hi,
To list the iptables rules loaded type:
$ iptables -L
In the output find the IP that you need.
To remove the rule, you need type the complete command whit the option -D, and the chain for example.
iptables -D INPUT -s 10.10.10.10/32 -j DROP
The option -j can be DROP or REJECT.
Also, check if in the file /etc/hosts.deny exist the IP Address, in this file, you can add IP Addresses to block.
Regards.
