[Bug 1885169] Re: Some arping version only accept integer number as -w argument

[Edward Hope-Morley]

I just tested arping on Focal and I dont see this issue:

ubuntu at arping:~$ sudo arping -U -I eth0 -c 1 -w 1.5 10.48.98.1
ARPING 10.48.98.1
42 bytes from fe:10:17:12:6a:9c (10.48.98.1): index=0 time=14.516 usec

--- 10.48.98.1 statistics ---
1 packets transmitted, 1 packets received,   0% unanswered (0 extra)
rtt min/avg/max/std-dev = 0.015/0.015/0.015/0.000 ms
ubuntu at arping:~$ dpkg -l| grep arping
ii  arping                         2.20-1                            amd64        sends IP and/or ARP pings (to the MAC address)

Not sure what i'm missing.
