Well, hours later...
I built this etherape from scratch and its first invocation showed me
this:
[EMAIL PROTECTED] root]# etherape
(EtherApe:4707): libglade-WARNING **: Unknown GtkToolbar child property:
sensitive
(EtherApe:4707): libglade-WARNING **: Unknown GtkToolbar child property:
sensitive
(EtherApe:4707): GLib-GObject-WARNING **: g_object_set_property: object class
`GtkTable' has no property named `orientation'
No nameservers defined.
[EMAIL PROTECTED] root]#
I suppose that duplicates your problem.
As far as I'm concerned this is typical of gnome shit and Linux software
in general and is one very good reason not to run it. Cruft. Amateur
programming. Undebugged portability. Huge libraries. Endless disk
space. Bonobos. Pangos. Druids. And the shit is still shit, and
doesn't work. At least this one isn't written in c-pus-pus.
So I started it -nonum, and it opened an absolutely unreadable display,
with various names in one column on the left (illegible colors, fixed
size, names are truncated -- AMATEUR NIGHT). On the right is some
ever-changeing goofball display with circles and triangles, in strange
colors. Clicking on help reveals the name of the wanker who wrote this
stuff five years ago, alias "Juan Toledo", and nothing else.
whilst running it shits forth meaningless yet scary error messages like:
(EtherApe:3764): GLib-GObject-WARNING **: g_object_set_property: object class
`GtkTable' has no property named `orientation'
(EtherApe:3764): Gtk-CRITICAL **: gtk_table_resize: assertion `n_cols > 0 &&
n_cols < 65536' failed
(EtherApe:3764): Gtk-CRITICAL **: gtk_table_resize: assertion `n_cols > 0 &&
n_cols < 65536' failed
(EtherApe:3764): Gtk-CRITICAL **: gtk_table_resize: assertion `n_cols > 0 &&
n_cols < 65536' failed
(EtherApe:3764): Gtk-CRITICAL **: gtk_table_resize: assertion `n_cols > 0 &&
n_cols < 65536' failed
(EtherApe:3764): Gtk-CRITICAL **: gtk_table_resize: assertion `n_cols > 0 &&
n_cols < 65536' failed
(EtherApe:3764): Gtk-CRITICAL **: gtk_table_resize: assertion `n_cols > 0 &&
n_cols < 65536' failed
(EtherApe:3764): Gtk-CRITICAL **: gtk_table_resize: assertion `n_cols > 0 &&
n_cols < 65536' failed
which means that the programming is unfinished and ships without
documentation (like all Linux projects) and contains active "assert"
macros in it. Maybe these are in the gtk bugware.
When activated -noname with all else as default, this pig consumes
32% of the CPU on a 1GHz Pentium III, displaying on another machine's
Xserver. Typical Linuxware.
the man page is a joke, and I'll be double-damned if I'll start delving
in the source code of this wankerware.
Well, I'm double-damned. Here's a typical comment from its main.c
/* TODO Besides the fact that this probably makes little sense nowadays
* (at least for node color) it probably leads to a segfault
* See how it is done for filter, for instance */
Bah.
OK, the error message comes from "dns.c"
void
dns_open ()
{
int option, i;
res_init ();
if (!_res.nscount)
{
fprintf (stderr, "No nameservers defined.\n");
exit (-1);
}
... other stuff ...
So evidently "res_init();" sets its return or something or other
in a sneaky (undocumented) global variable _res.nscount; if it's
zero show you the error. Bad style. _res.nscount is a count, the
test should be if(_res.nscount == 0) and no, that's not nit-picking.
Let's look at this res_init() villain -- it's part of the resolver
library, i.e. the C library. There's a man page for it.
That manpage says nothing about success or failure of res_init().
It does not say what res_init() might do.
Well, consider li'l foo.c here:
#include <sys/types.h>
#include <netinet/in.h>
#include <arpa/nameser.h>
#include <resolv.h>
main()
{
res_init();
printf("%u\n", _res.nscount);
return 0;
}
compiled and run on the same box that etherape complains about,
it prints "1". Hmmmm.
I don't know what's causing this error. My suspicion is that this
gnome stuff, bonoboware, whatever, is compiled with threads and that
it is relying on this static variable "_res", defined in libc, to
be useful in more than one thread.
Well, I went to dns.c, blocked out the error-checking for _res.nscounts,
and the thing ran, but still didn't print the names of the hosts,
just the IP numbers.
It is not clear to me that the author is without blame. I'd suggest
talking to him.
The other errors at run-time would be sufficient to make me delete the
package.
Can I suggest 'ethereal' instead? This has been withdrawn from the
ports for some reason. I'm currently sucking in the source code
and will report back later if it works. I recall it used to.
Sorry for my general nastiness but I've sunk about six hours in this,
only to discover undocumented bloated Linuxware. You can tell I don't
like gnome, Linux, or eyecandy. From what I can guess from the undocumented
etherape program, one could get the same information from "netstat",
or write a much smaller program to display the same information
using ncurses(3). Using 33% of a pretty snappy CPU to display what
it's displaying is simply inexcusable. Test and admin ware should
not impinge on the operating system. Most of the stuff etherape
reported to me looked like its own traffic to the Xserver. Tsk. Tsk.
Please tell me exactly what you want from etherape, and I'll try to
figure out another way to get it. I don't want to fix its bug with
the resolver. The maintainer of the etherape port is
Craig Barraclough <[EMAIL PROTECTED]>
I think you might do well to ask him about this resolver problem,
tell him it is still present in 4.0.
If you *have* to have it, and it *has* to work, install the red-hat
Linux emulation, and install a Linux binary of etherape (and all its
gnome crap), and run it that way. THe preceding applies to other
Linux programs.
