I'm getting this error in Putty: Server unexpectedly closed network connection Anyone knows how to fix it? All search results show to turn off UseDNS no but I'm not even using dns. I connect to IP directly. Anyway, tried that and it didn't work. I'm able to connect from other locations. just one computer got blocked. I can't find anything in logs, tried to reinstall ssh, ssh-openserver, fail2ban. I'm on Debian Lenny installed using Perfect Server manual.
How many failed login attempts did you make from this computer? I guess fail2ban is blocking that computer.
that's what I thought too. I did about 5 failed connections. I tried to uninstall fail2ban and also there was nothing in the iptables -L Any ideas?
Thank you. I found that link online too. And followed the steps. I did not have blocked IP in my list. I also did apt-get remove fail2ban.
Yes, I was able to connect from other IPs and yes, my blocked IP was listed there. Thank you so much! I removed and it's now working again! Thank you!
I post this just to inform people, my host was adding me automatically to /etc/hosts.deny so i had to erase my IP from /etc/hosts.deny and add it to /etc/hosts.allow I hope this can solve other people problems too
