Recent problem where I needed to VNC to a host but the host was not directly routable. So I needed to send my traffic to a routable host and then tunnel it over to the final target host. SSH did the trick here:
|
1 |
ssh -g -L rhost:5900:host:5900 host |
Where “rhost” is the intermediate server and “host” is the final target server.
Here’s a quick bit of apache config that can be placed in the conf/vhost.conf file of a Plesk site to turn off the open_basedir restrictions:
|
1 2 3 4 5 6 |
<Directory /var/www/vhosts/somedomain.com/httpdocs> php_admin_flag engine on php_admin_value open_basedir none </Directory> |
I can never remember this command! When you want to add a vhost.conf file to a Plesk managed website, the following command needs to be run to force Plesk to add an include statement for the vhost.conf file:
|
1 |
/usr/local/psa/admin/sbin/websrvmng -a -v |

For public DNS servers it is often desirable to disable recursive name resolution. This can be accomplished by adding:
|
1 |
recursion no; |
to the “options” section of the /etc/named.conf file. Alternately you might want to only allow recursion for a limited range of addresses. This can be accomplished by instead adding a line like this:
|
1 |
allow-recursion { 127.0.0.1/24; }; |
to the “options” section of the /etc/named.conf file.
