Traceroute is known to build and run under SunOS 4.1.4 and Solaris 5.4.
|
|
If you are running a really old kernel, see the instructions under the
|
|
title "KERNEL MODIFICATIONS" further down.
|
|
|
|
To build traceroute, first customize any paths in Makefile.in, then run
|
|
"./configure" (a shell script). The configure script will determine
|
|
your system attributes and generate an appropriate Makefile from
|
|
Makefile.in. Next run "make". If everything goes well you can su to
|
|
root and run "make install" and "make install-man". Note that traceroute
|
|
must be installed setuid to root or run as root.
|
|
|
|
If configure fails for some reason and decide to submit a bug report to
|
|
traceroute@ee.lbl.gov, please include a copy of config.log.
|
|
|
|
You will need an ANSI C compiler to build libpcap. The configure script
|
|
will abort if your compiler is not ANSI compliant. If this happens, use
|
|
the GNU C compiler, available via anonymous ftp:
|
|

KERNEL MODIFICATIONS
|
|
--------------------
|
|
If yor have a really old system, it may be necessary to modify your
|
|
kernel before traceroute will work. If you want to hack on your kernel,
|
|
a modified version of the routine rip_output (normally found in the
|
|
file /sys/netinet/raw_ip.c) can be found in rip_output.c. This code may
|
|
or may not resemble the code in your kernel. It may offer you a place
|
|
to start but we make no promises. If you do hack your kernel, remember
|
|
to test everything that uses raw ip sockets (e.g., ping and
|
|
egpup/gated) & make sure they still work. We wish you the best of luck
|
|
and you're on your own.
|
|
|
|
Some older kernels forward icmp packets that have a ttl of zero. If
|
|
your system has this bug, you might want to fix it while you're in the
|
|
kernel. (This bug appears in all releases of BSD up to but not
|
|
including 4.3tahoe. If your version of netinet/ip_icmp.c is any earlier
|
|
than 7.3 (April, '87), it has the bug.) The fix is just to add the
|
|
line:
|
|
|
|
ip->ip_ttl = MAXTTL;
|
|
|
|
after the line:
|
|
|
|
ip->ip_src = t;
|
|
|
|
(or anywhere before the call to icmp_send) in routine icmp_reflect.
|
|
|
|
If you're running this on a pre-4.3bsd system (e.g., SunOS 3) that
|
|
strips ip headers from icmp messages, add -DARCHAIC to CFLAGS in the
|
|
Makefile. Also note that rip_output contains a conditional for a
|
|
4.2/4.3 change in the location of a raw socket's protocol number. I've
|
|
checked this under 4.3 & SunOS 3 but you should double-check your
|
|
system to make sure the appropriate branch of the #if is taken (check
|
|
the line that assigned to ip->ip_p in your system's original
|
|
rip_output).
