I wouldn't say that. It is just a familiarity thing. You knew how to
do this in Coyote Linux and now are struggling with how to do it in
DCD. Many people who help out on the list started out just like you.

The most important thing here is you helped yourself out. You posted
the part of /etc/network.conf that you are struggling with. That helps
people help you. Moreover, if you post directly to the list, you may
have already had an answer by now. In addition, it gives people a
chance to chime in if advice is not correct, etc.
0/0 is a convention to refer to your dynamic or static ip address. You
need to allow the domain and bootpc through. bootpc is actually a name
for a port found in /etc/services. bootpc refers to port 68. The
neo-modus.com stuff does not have a named port so you just use the
number that the neo-modus.com Direct Connect requires, 412.
EXTERN_UDP_PORTS should look like this. Just at to the list inside the
quotes. Like so.
NOTE: that the following set of changes are made in /etc/network.conf.
## UDP Services open to outside world
# Space seperated list: srcip/mask_dstport
# NOTE: bootpc port is used for dhcp client
EXTERN_UDP_PORTS="0/0_domain 0/0_bootpc 0/0_412"
If you need to add additional ports in the future, just add a space and
another port number.
Delete the two commented lines below the EXTERN_UDP_PORTS i.e.
> #EXTERN UDP PORTS="0/0_411"
> #EXTERN UDP PORTS="0/0_412"
Note that there are two ways to perform this task. I am telling you to
use the first one. So now we have to clean up the second method.
Delete the two lines that look like this below.
EXTERN_UDP_PORT2="0/0 411 192.168.0.2"
EXTERN_UDP_PORT#="0/0 412 192.168.0.2"
> # -or-

> EXTERN_UDP_PORT2="0/0 411 192.168.0.2"
> EXTERN_UDP_PORT#="0/0 412 192.168.0.2"
The problem here is that you have two definitions. The first one was
for the incorrect port 411, but it was replaced with the correct 412.
Please delete this line from the group below in /etc/network.conf.
EXTERN_TCP_PORTS="0/0_411"
> # TCP services open to outside world
> # Space seperated list: srcip/mask_dstport
> EXTERN_TCP_PORTS="0/0_411"
> EXTERN TCP PORTS="0/0_412"
Ok now you have openned up the ports in the firewall with the above
steps as per Direct Connect's FAQ. Now you have to forward them to you
host on your internal network. Please look for the "# Port Forwarding"
section of the /etc/network.conf file. You are looking specifically for
this line.
#INTERN_SERVERS="tcp_${EXTERN_IP}_ftp_192.168.1.1_ftp
tcp_${EXTERN_IP}_smtp_192.168.1.1_smtp"
I do not know what your current line looks like. My instructions will
presume that you have no other services forwarded. If you do you will
have to add them to the list. This is a space seperated list just like
the others we have modified. I believe this is how INTERN_SERVERS
should look like. Please note the my email client may have broken this
line up at the space. This should all be one line in your editor! Also
note that I have changed the default port of 192.168.1.1 to the ip
address you tried below of 192.168.0.2. That doesn't look correct but
go for it.
INTERN_SERVERS="tcp_${EXTERN_IP}_412_192.168.0.2_412
udp_${EXTERN_IP}_412_192.168.0.2_412"
Finally, backup etc.lrp.
Ok I am just wondering. You may have to experiment some. It says in
their FAQ that you have to plug in your external IP address. If you are
port forwarding to this machine with the Direct Conenct software, I
wonder if you realy have to configure the external IP. You will have to
try the software with and without the IP configuration. See part of
their FAQ I copied below in my original response to you. Port
forwarding presents the connection right to your internal machine and
estentially defeats the NAT in a way. Perhaps their software has to
make use of the external IP for some reason?

By the way, if you have ssh working, you're not so dumb as you think.
You are missing at least one space. ., dot, in front of a file means
that it is supposed to be a hidden file. Regardless of being root or a
normal user, you were instructing Linux to treat this as an executable
file. Linux tried to execute the "hidden" file, but the file
permissions were not correct for an executable file. Hence, the
"permission denied" message. If you ls -l /etc/network.conf you may see
-rw-r--r-- in the leftmost part of the ls output. If you ls -l /bin/sed
you may see -rwxr-xr-x. The 'x' makes it an executible file. By the
way, you do not need to change these.
That was not the intent of what I was trying to get you to do. If you
use dot space filename, it is a Bash/ash shortcut to pull in the
information contained in the file. Please try this. Note that I have
put three spaces between the ., dot and the filename for clarity.
. /etc/network.conf
Now you have all the environment variables available to you from
/etc/network.conf. Just use the echo command to see what is in one of
the variables.
echo $EXTERN_IP
I hope this helps,
Greg Morgan
