Hi ctsgnb,
the "default option" works also without the colon.
I'd be most grateful for any help on 2. question (on choosing max. TTL) ...
and of course any correction on my "thinking" in 1. point (on -c switch).
ADD: I think I should let ping run inside the for loop, until I'd get ECHO_REPLY, and then break the for loop.
Code:
PING www.l.google.com (209.85.135.99) 56(84) bytes of data.
From 209.85.253.26 icmp_seq=1 Time to live exceeded
--- www.l.google.com ping statistics ---
1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms
Here should be the break-like statement: above is TTL_EXPIRED, below ECHO_REPLY. Is that right?
PING www.l.google.com (209.85.135.99) 56(84) bytes of data.
64 bytes from mu-in-f99.1e100.net (209.85.135.99): icmp_req=1 ttl=250 time=45.0 ms
--- www.l.google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 45.052/45.052/45.052/0.000 ms

Hi,
I am using su within a for loop. As you might expect, it prompts for password during each loop execution. Here is my piece of code:

USER_ID=`echo $i | awk -F "|" '{ print $2 }'`

Running 3650 switch. I have this odd issue where I cannot get 4 new Centos 7 boxes pinging out on public IPs (nor pinging in), only gateway .1 and first public IP .2

TRACEROUTE6(8) System Manager's Manual: iputils TRACEROUTE6(8)NAME
traceroute6 - traces path to a network host
SYNOPSIS
traceroute6 [-dnrvV] [-i interface] [-m max_ttl] [-p port] [-q max_probes] [-s source] [-w wait time] destination [size]
DESCRIPTION
Description can be found in traceroute(8), all the references to IP replaced to IPv6. It is needless to copy the description from there.
SEE ALSO traceroute(8), tracepath(8), ping(8).
HISTORY
This program has long history. Author of traceroute is Van Jacobson and it first appeared in 1988. This clone is based on a port of tracer-
oute to IPv6 published in NRL IPv6 distribution in 1996. In turn, it was ported to Linux by Pedro Roque. After this it was kept in sync by
Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>. And eventually entered iputils package.
SECURITY
tracepath6 requires CAP_NET_RAWIO capability to be executed. It is safe to be used as set-uid root.
AVAILABILITY
traceroute6 is part of iputils package and the latest versions are available in source form at http://www.skbuff.net/iputils/iputils-cur-
rent.tar.bz2.
