Question

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?

Use the console and flush your iptables. And in the future, don’t copy/paste random iptable rules. Use csf/lfd.

Now I have new problem. I cant type anything to console or it freezes. Even see some weird escape characters. Basicly cant type any command in it. Tried Chrome and Firefox Portable on Win7 x64.
