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

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.

Then ping mutiple server:

pingtop baidu.com google.com twitter.com

This project is usingclick. Check help infowithpingtop -h.

~ pingtop --helpUsage: 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.

We use ICMP socket to send ping packet withoutsudo (Seethispostby lilydjwg(in Chinese)), however, who(which group) can use this featureis controled by a kernel parameter:net.ipv4.ping_group_range.

cat /proc/sys/net/ipv4/ping_group_range1    0

The default value is1 0, this means the whose group number from 1to 0 can use this feature(which means nobody can use this), so you get aPermission denied .

To fix this, change this variable to a proper range include your groupid, like this:

[vagrant@centos7 pingtop]$ iduid=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
