Oh, yet again :-(
It does not work with both fake ppp0 and lo0.
These are my expirience: (sorry for big mail)
---------------
ifconfig before I run gdomap:
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
This is first time I run gdomap:
SIOCGIFFLAGS: Device not configured
SIOCGIFFLAGS: Device not configured
SIOCGIFBRDADDR: Invalid argument
SIOCGIFFLAGS: Device not configured
SIOCGIFFLAGS: Device not configured
This is second:
SIOCGIFFLAGS: Device not configured
SIOCGIFFLAGS: Device not configured
SIOCGIFBRDADDR: Invalid argument
SIOCGIFFLAGS: Device not configured
SIOCGIFFLAGS: Device not configured
Unable to bind address to UDP socket
This is third (this worked two days ago, and I sent mail with SOLVED):
darkstar# ifconfig ppp0 192.168.5.2 192.168.5.1
darkstar# route add -host 192.168.5.2 127.0.0.1
add host 192.168.5.2: gateway 127.0.0.1
darkstar# logout
%opentool gdomap
%SIOCGIFFLAGS: Device not configured
SIOCGIFFLAGS: Device not configured
SIOCGIFFLAGS: Device not configured
SIOCGIFBRDADDR: Invalid argument
SIOCGIFFLAGS: Device not configured
SIOCGIFFLAGS: Device not configured
Unable to bind address to UDP socket
This is gdomap's help. These is info how it finds network interfaces:
Gdomap normally probes every machine on the local network to see if there
is a copy of gdomap running on it. This is done for class-C networks and
subnets of class-C networks. If your host is on a class-B or class-A net
then the default behaviour is to treat it as a class-C net and probe only
the hosts that would be expected on a class-C network of the same number.
If you are running on a class-A or class-B network, or if your net has a
large number of hosts which will not have gdomap on them - you may want to
supply a configuration file listing the hosts to be probed explicitly,
rather than getting gdomap to probe all hosts on the local net.
You may also want to supply the configuration file so that hosts which are
not actually on your local network can still be found when your code tries
to connect to a host using @"*" as the host name. NB. this functionality
does not exist in OpenStep.
A configuration file consists of a list of IP addresses to be probed.
The IP addresses should be in standard 'dot' notation, one per line.
Empty lines are permitted in the configuration file.
Anything on a line after a hash ('#') is ignored.
You tell gdomap about the config file with the '-c' command line option.
gdomap uses the SIOCGIFCONF ioctl to build a list of IP addresses and
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is info
netmasks for the network interface cards on your machine. On some operating
systems, this facility is not available (or is broken), so you must tell
gdomap the addresses and masks of the interfaces using the '-a' command line
option. The file named with '-a' should contain a series of lines with
space separated pairs of addresses and masks in 'dot' notation.
You must NOT include loopback interfaces in this list.
If your operating system has some other method of giving you a list of
network interfaces and masks, please send me example code so that I can
implement it in gdomap.
netstat -na after my tryings:
Active Internet connections (including servers)
Proto Recv-Q Send-Q Local Address Foreign Address (state)
tcp4 0 0 *.538 *.* LISTEN
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this is gdomap
tcp4 0 0 *.6000 *.* LISTEN
tcp4 0 0 *.587 *.* LISTEN
tcp4 0 0 *.25 *.* LISTEN
tcp4 0 0 *.79 *.* LISTEN
tcp4 0 0 *.513 *.* LISTEN
tcp4 0 0 *.514 *.* LISTEN
tcp4 0 0 *.23 *.* LISTEN
tcp4 0 0 *.21 *.* LISTEN
tcp4 0 0 *.111 *.* LISTEN
tcp4 0 0 127.0.0.1.53 *.* LISTEN
udp4 0 0 *.538 *.*
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this is gdomap
udp4 0 0 *.518 *.*
udp4 0 0 *.512 *.*
udp4 0 0 *.111 *.*
udp4 0 0 *.1024 *.*
udp4 0 0 127.0.0.1.53 *.*
udp4 0 0 *.514 *.*
So gdomap have used socket, but didnt run :-(
