Can't login to droplet after iptables command
After seeing multiple fail attempts to login using SSH from intruder I found this solution on http://unix.stackexchange.com. After second command console tab freezed and connection to droplet was droped.
iptables -A INPUT -p tcp –dport 22 -m recent –update –seconds 60 –hitcount 4 –name SSH –rsource -j DROP
iptables -A INPUT -p tcp –dport 22 -m recent –set –name SSH –rsource -j ACCEPT
Now I have the problem to login to my droplet via SSH and I’m getting these messages.
OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007
debug1: Reading configuration data /c/Users/Milan/.ssh/config
debug1: Connecting to <droplet-ip> [<droplet-ip>] port 22.
debug1: connect to address <droplet-ip> port 22: Attempt to connect timed out without establishing a connection
ssh: connect to host <droplet-ip> port 22: Bad file number
Does someone knows how to fix that?
