Hello,
I checked the ping6 command from the latest version of busybox(1.35.0).
root@-virtual-machine:/home/# ./busybox_PING6
Usage: ping6 [OPTIONS] HOST
Send ICMP ECHO_REQUESTs to HOST
-c CNT Send only CNT pings
-s SIZE Send SIZE data bytes in packets (default 56)
-i SECS Interval
-A Ping as soon as reply is recevied
-I IFACE/IP Source interface or IP address
-W SEC Seconds to wait for the first response (default 10)
(after all -c CNT packets are sent)
-w SEC Seconds until ping exits (default:infinite)
(can exit earlier with -c CNT)
-q Quiet, only display output at start/finish
-p HEXBYTE Payload pattern
It does not show -t. option, but when i give -t option , it is not throwing
an error also. An echo request is sent with TTL of 64.
root@virtual-machine:/home# ./busybox_PING6 3001::22 -t 100
PING 3001::22 (3001::22): 56 data bytes
64 bytes from 3001::22: seq=0 ttl=64 time=0.062 ms
64 bytes from 3001::22: seq=1 ttl=64 time=0.093 ms
64 bytes from 3001::22: seq=2 ttl=64 time=0.079 ms
^C
Busybox ping6 really supports the "TTL" option ?? if so ..is there a way to
enable that ??
Thanks,
Nag
