I have install glassfish in my ubuntu droplet, now when i start the glashfish server using ssh command its closes the session when i close the ssh. so i would like to uninstall and install again with the list of step i have found in other sites; or if anyone can help me to overcome this challenge.
The easiest method would be to use apt, by running:
sudo apt-get remove glassfish-* \
&& sudo apt-get purge glassfish-*
It’ll ask you to confirm the removal each time. You can also auto-answer yes by running:
sudo apt-get -y remove glassfish-* \
&& sudo apt-get -y purge glassfish-*
What the above commands do is:
1). Removes the installation
2). Removes the configuration left behind.
I take a snopshot of a instance and deploy as a new droplet. SFTP username and password is same. I want to change that. Is there any command to update SFTP username and password. Thank You
Hi I've been getting these errors in my apache error log (/var/log/apache2/error.log) - ``` [Fri Jul 14 20:03:05.655198 2017] [:error] [pid 27999] [client 158.69.6.133:52294] script '/var/www/html/wp-login.php' not found or unable to stat [Sat Jul 15 00:47:36.775033 2017] [:error] [pid 30209] [client 91.196.50.33:55531] script '/var/www/html/testproxy.php' not found or unable to stat ``` I've installed fail2ban and can see in the log (/var/log/fail2ban.log) its been banning IPs for the jails setup - ``` 2017-07-15 01:01:11,573 fail2ban.actions: WARNING [wordpress-login] Ban 78.188.97.162 2017-07-15 07:48:29,518 fail2ban.actions: WARNING [wordpress-xmlrpc] Ban 79.113.42.94 2017-07-15 07:48:30,312 fail2ban.actions: WARNING [http-get-dos] Ban 113.62.25.96 2017-07-15 07:57:15,893 fail2ban.actions: WARNING [ssh] Ban 165.227.8.24 2017-07-15 07:57:16,139 fail2ban.actions: WARNING [apache-nokiddies] Ban 220.130.181.50 ``` What can I do to stop wp-login.php and testproxy.php from appearing in the apache error log?

How can I add www to my URL? I followed the instructions for setting a host name [here](https://www.digitalocean.com/community/tutorials/how-to-set-up-a-host-name-with-digitalocean), but whenever I browse for http://www.foo.com, I get redirected to http://foo.com. How do constantly keep www.foo.com? I have the following DNS records: Type | Hostname | Value | TTL (seconds) ------------- | ------------- | ------------- | ------------- CNAME | *.foo.com | is an alias of www.foo.com. | 43200 A | foo.com | directs to 201.227.660.894 | 3600 A | www.foo.com | directs to 201.227.660.894 | 3600 NS | foo.com | directs to ns1.digitalocean.com. | 1800 NS | foo.com | directs to ns2.digitalocean.com. | 1800 NS | foo.com | directs to ns3.digitalocean.com. | 1800
