Linux – Ping multiple hosts using fping

 
fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up.
With fping we can ping multiple hosts at a time. Use following command to ping multiple hosts:
$ fping -f IPsFiles.txt 
where in IPsFiles.txt I have multiple hots.
Below are some other examples of fping:
To ping a host/IP:
$ fping 192.168.2.2
Output:

OpenSSL is not properly installed on your system – Ubuntu

While trying to install some module I got error saying that “OpenSSL is not properly installed on your system ubuntu”.
I tried to reinstall this module after installing openssl, but no luck.
After debugging and exploring for a while I got to know that installing libssl-dev could resolve this issue, so I installed libssl-dev with following command:
$ sudo apt-get install libssl-dev
Now retried installation and it worked like charm.

Once again about pros/cons of Systemd and Upstart

Upstart advantages.
1. Upstart is simpler for porting on the systems other than Linux while systemd is very rigidly tied on Linux kernel opportunities.Adaptation of Upstart for work in Debian GNU/kFreeBSD and Debian GNU/Hurd looks quite real task that it is impossible to tell about systemd;
2. Upstart is more habitual for the Debian developers, many of which in combination participate in development of Ubuntu. Two members of Technical committee Debian (Steve Langasek and Colin Watson) are a part of group of the Upstart developers.
