Re: ping options

Out of curiosity to check this DF thing and to have a decent tool also in PASE, I downloaded the "fping" last sources and compiled it in PASE using gcc.
The tool is useful because supports ranges etc. so I'll keep it installed on the partition, it works fine but when asked to "not fragment" it says as below.
Does somebody have access to a real AIX with the possibility to check if AIX allows it in stock ping (ping -f)??thanks

-bash-5.2$ ./fping -M 9.9.9.9
./fping, -M option not supported on this platform


-bash-5.2$ ./fping --help
Usage: ./fping [options] [targets...]

Probing options:
   -4, --ipv4         only ping IPv4 addresses
   -6, --ipv6         only ping IPv6 addresses
   -b, --size=BYTES   amount of ping data to send, in bytes (default: 56)
   -B, --backoff=N    set exponential backoff factor to N (default: 1.5)
   -c, --count=N      count mode: send N pings to each target and report stats
   -f, --file=FILE    read list of targets from a file ( - means stdin)
   -g, --generate     generate target list (only if no -f specified),
                      limited to at most 131072 targets
                      (give start and end IP in the target list, or a CIDR address)
                      (ex. ./fping -g 192.168.1.0 192.168.1.255 or ./fping -g 192.168.1.0/24)
   -H, --ttl=N        set the IP TTL value (Time To Live hops)
   -i, --interval=MSEC  interval between sending ping packets (default: 10 ms)
   -l, --loop         loop mode: send pings forever
   -m, --all          use all IPs of provided hostnames (e.g. IPv4 and IPv6), use with -A
   -M, --dontfrag     set the Don't Fragment flag
   -O, --tos=N        set the type of service (tos) flag on the ICMP packets
   -p, --period=MSEC  interval between ping packets to one target (in ms)
                      (in loop and count modes, default: 1000 ms)
   -r, --retry=N      number of retries (default: 3)
   -R, --random       random packet data (to foil link data compression)
   -S, --src=IP       set source address
       --seqmap-timeout=MSEC sequence number mapping timeout (default: 10000 ms)
   -t, --timeout=MSEC individual target initial timeout (default: 500 ms,
                      except with -l/-c/-C, where it's the -p period up to 2000 ms)
       --check-source discard replies not from target address
       --icmp-timestamp use ICMP Timestamp instead of ICMP Echo

Output options:
   -a, --alive        show targets that are alive
   -A, --addr         show targets by address
   -C, --vcount=N     same as -c, report results (not stats) in verbose format
   -d, --rdns         show targets by name (force reverse-DNS lookup)
   -D, --timestamp    print timestamp before each output line
       --timestamp-format=FORMAT  show timestamp in the given format (-D required): ctime|iso|rfc3339
   -e, --elapsed      show elapsed time on return packets
   -J, --json         output in JSON format (-c, -C, or -l required)
   -n, --name         show targets by name (reverse-DNS lookup for target IPs)
   -N, --netdata      output compatible for netdata (-l -Q are required)
   -o, --outage       show the accumulated outage time (lost packets * packet interval)
   -q, --quiet        quiet (don't show per-target/per-ping results)
   -Q, --squiet=SECS[,cumulative]  same as -q, but add interval summary every SECS seconds,
                                   with 'cumulative', print stats since beginning
   -s, --stats        print final stats
   -u, --unreach      show targets that are unreachable
   -v, --version      show version
   -x, --reachable=N  shows if >=N hosts are reachable or not
   -X, --fast-reachable=N exits true immediately when N hosts are found
       --print-tos    show received TOS value
       --print-ttl    show IP TTL value

Hi

I had a request to run a ping on the IBMi and specify the -f option to stop fragmentation.

The green screen option does not support specifying this option.

I searched and there was supposed to be an option in iNavigator but I think that referred to the old version as I could not find it.

I tries the PASE environment but got "ping not found" and system ping also does not seem to support any switches.

Hopefully I am just not looking hard enough ?

Thanks
