Pingtop 0.4.2

Description:

pingtop 0.4.2

Ping multiple servers and show the result in a top like terminal UI.

Install
pip install pingtop
** pingtop support Python3.8 Python3.8. **
There is a dependency (blist <http://stutzbachenterprises.com/blist/>) not supporting Python3.9, so please pingtop can’t support 3.9.

Usage
Then ping mutiple server:
pingtop baidu.com google.com twitter.com
This project is using
click. Check help info
with pingtop -h.
~ pingtop --help
Usage: pingtop [OPTIONS] [HOST]...

Options:
-s, --packetsize INTEGER specify the number of data bytes to be sent.
The default is 56, which translates into 64
ICMP data bytes when combined with the 8
bytes of ICMP header data. This option
cannot be used with ping sweeps. [default:
56]
-l, --logto PATH
-v, --log-level [DEBUG|INFO|WARNING|ERROR|CRITICAL]
--help Show this message and exit.

Why do I get Permission denied ?
We use ICMP socket to send ping packet without sudo (See this
post
by lilydjwg(in Chinese)), however, who(which group) can use this feature
is controled by a kernel parameter: net.ipv4.ping_group_range.
cat /proc/sys/net/ipv4/ping_group_range

1 0
The default value is 1 0, this means the whose group number from 1
to 0 can use this feature(which means nobody can use this), so you get a
Permission denied .
To fix this, change this variable to a proper range include your group
id, like this:
[vagrant@centos7 pingtop]$ id
uid=1000(vagrant) gid=1000(vagrant) groups=1000(vagrant) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

[vagrant@centos7 pingtop]$ sudo sysctl -w net.ipv4.ping_group_range='0 1001'
net.ipv4.ping_group_range = 0 1001
