PV can report progress for large data imports. In this example I will use a large (7 G) install on Ubuntu. First, download PV (http://linux.die.net/man/1/pv)
sudo apt-get install pv
A traditional mysql import may be formatted as:
mysql -u USER -p DATABASE_NAME < DUMP.mysql

Your import will report progress and an ETA đ

Letâs Encrypt for cPanel Installation using Installing the cPanel Plugin
Log into your SSH client at root level, then add the Letâs Encrypt repository with the following command:
cd /etc/yum.repos.d/ && wget https://letsencrypt-for-cpanel.com/static/letsencrypt.repo

le-cp self-test [SELF-TEST] Can read config ............ SUCCESS. [SELF-TEST] Can connect to daemon and check licence ............ SUCCESS. [SELF-TEST] Can connect to Lets Encrypt ............ SUCCESS. [SELF-TEST] Can talk to WHM API ............ SUCCESS. [SELF-TEST] Can talk to plugin RPC ............ SUCCESS.
You can log in to your cPanel account and install your first SSL certificate.

From the XenServer Command Line Interface (CLI), issue the following command:
xe pif-list
Press Enter.
Note: If you have more than one XenServer in the pool, you must issue the xe host-list command to list all the XenServer hosts and write down the Universally Unique Identifier (UUID) of the host that you added the new NIC, then issue command xe pif-list host-uuid=[uuid of the XenServer host]
The preceding command lists all the physical NICs of that XenServer. If you do not see the additional NIC, you must scan for new physical interface(s) on a XenServer and issue this command:
xe pif-scan host-uuid=[uuid of the XenServer host]
Press Enter. Continue reading “How to Add Additional Physical NICs to XenServer” »
