Does clicking on your start menu search results do nothing? Have you updated/removed Windows language packs recently?
This may solve your problem:
To see which services are started up on boot, run the following:
chkconfig --list systemctl list-unit-files
The default port and protocol for OpenVPN is UDP/1194.
Some server admins may block port 1194 so to get around this we can set OpenVPN to listen on port 443 instead. Port 443 is the default for HTTPS traffic so there is little chance it will be blocked.
To install OpenVPN on CentOS I recommend using this guide: https://www.digitalocean.com/community/tutorials/how-to-setup-and-configure-an-openvpn-server-on-centos-7
If you are running a web server, the chances are nginx/apache is already listening on port 443 and we can’t have more than one application binding to the same port. Once solution is to get nginx/apache to listen for HTTPS traffic on another port (e.g 22443) and get OpenVPN to listen on port 443 (forwarding all traffic to the port 22443).
First change the listen port for your web server (apache):
sudo vi /etc/httpd/conf/httpd.conf
Modify mod_ssl (you can choose any un-used port number):
</IfModule mod_ssl.c> Listen 22443 </IfModule>
Check if port 443 is used in other config files and replace accordingly:
sudo grep '443' -r /etc/httpd/*
Modify OpenVPN server.conf:
sudo vi /etc/openvpn/server.conf
Change protocol to tcp, port 1194 to 443 and add a port-share for 22443 (your new web server port for HTTPS)
proto tcp port 443 port-share 127.0.0.1 10443
You will also have to change your ovpn config file to use the new settings:
client dev tun proto tcp remote your_server_ip 443 resolv-retry infinite nobind persist-key persist-tun comp-lzo verb 3 ca /path/to/ca.crt cert /path/to/client.crt key /path/to/client.key
Finally restart your web server and OpenVPN services:
sudo systemctl restart email@example.com sudo systemctl restart httpd
This year I have many important goals…
When an IP is banned by Fail2Ban and you want to un-ban that IP, the command you need to run is:
sudo fail2ban-client set <jailname> unbanip ipaddress
You can get the jailname by running:
sudo fail2ban-client status
If you want to find what IPs are banned by Fail2Ban, you can check the IPTABLES by running:
sudo iptables -L -n
An example output would be:
Chain f2b-sshd (1 references) target prot opt source destination REJECT all -- 22.214.171.124 0.0.0.0/0 reject-with icmp-p ort-unreachable(1 references
To unban IP 126.96.36.199 from the sshd jail, the command would be:
sudo fail2ban-client set sshd unbanip 188.8.131.52
