I don't understand whats going on with my rootserver...
I have reset iptables and just opened the port for ssh.
Now suddenly over night I see that there are a various of ports open:
21,80, 135, 139, 445, 3128
Could it be that vsftpd for example put rules in automatically to allow input on port 21?
I also tried disabling iptables with this command:
I used an online tool to create an iptables firewall. Basically I just need port 22 and 1194 open to the outside world. But I noticed this bash script has input, forward and output chains as accept by default. Is it blocking all traffic but those two ports? Thanks.
I am running a server which needs UDP ports 1000:11000 opened, as well as TCP 10011 and 30033 open to function.
I have a set of iptables rules set to allow SSH and those ports, and intentionally left out 2010 as I am getting attacked on that port. The server does not block the incoming IP even when told to do so.
I'm trying to set up iptables to block all traffic except ssh but, no matter what I do, it's blocking outgoing ssh. The commands that I'm using are shown below. Oddly, I can SSH into the box, just not out.
