rpaulo fc5eb63af6 It doesn't make sense to print the MPLS ttl here. 
While here, make the output look like Cisco IOS. Suggested by Mihai CHELARU.

mrg 0c37c63edc change (mostly) int to socklen_t. GCC 4 doesn't like that int and 
socklen_t are different signness.

rpaulo 39c9cdcdbf Show MPLS ICMP extensions. Only available if -M is passed. 
Example:
	RC02-02 (195.245.142.66)  45.707 ms  20.418 ms  34.042 ms [MPLS: label: 515, exp: 0x0, ttl: 1]
	gr1-p340.attga.ip.att.net (12.123.20.190)  241.878 ms  251.945 ms [MPLS: label: 32133, exp: 0x0, ttl: 1]


Based on PR 22523: By Jesper Skriver (updated by ww@parc.styx.org and Mihai
CHELARU).

Things not in the PR that I changed/added:
       * changed exp and label to lower case
       * added ttl (probably not worth it but who knows..)
       * KNF/style/indent
       * C99 uintXX_t

sommerfeld 802499fd1c Avoid using savestr() on something which will later be passed to 
free().  Raised as a potential security issue on bugtraq.  No actual
exploits known.

sommerfeld 0cd03c86b4 Fix use of -I and -P at the same time by refactoring so there's only 
one set of code which knows how to resize the packet.
Report when we shrink MTU because of an EMSGSIZE return; fix
formatting to let this not look ugly.
Add a few likely MTU's to the table (1480 and 1280).

itojun e33da94c5b configure IPsec policy on sending/receiving socket for bypassing IPsec. 
If IPsec default policy is configured for destination
traceroute will never success (because encrypted icmp timexceeded
is unrecognizable).
 1999-09-03 03:10:38 +00:00
kim 6f775308a6 Only require half of the responses to indicate that the destination is 
unreachable.  This makes traceroute exit when it encounters a Cisco, which
typically does not respond to every other probe (or so) when either there
is no route to the destionation or an access list is blocking the probes.

cjs b8bcd9b643 If not root, make sure source address matches a local interface. 1999-02-16 23:18:40 +00:00
cjs 8164a79fad Check select() return value, and abort the program if an error is 
returned.  Otherwise after sending a packet, select() may return
immediately (if there's an error of some sort) and traceroute
solders on, sending more packets with no delay in between. This is
effectively a small flood attack.
