FTP support in NDN/DOS (Announce)

Hi everyone.

I ususally don't announce for NDN here myself, but since
the latest release of NDN for DOS contains a FTP implementation
I'd like to ask interested users of this forum to try it out.

You need a working packet driver installed for this to work.
The rest should work out of the box.

Hello Stefan!
Thanks for your effort!

I downloaded and tried this new version.
Unfortunately the FTP stuff doesn't work for me. I tried it on two computers - with Realtek RTL8129 and Realtek RTL8139 but the result is the same:
if I want to connect to FTP site it reports error message Socket error 11001 "GetHostByName(): Failed"
Tried with WATTCP.CFG variable set (in WATTCP.CFG file I have manualy written my network configuration) and also without this variable - so it should use DHCP.
Other my DOS internet software works fine.

I don't know what is bad. Maybe wold help some debug version of NDN which would create some log file about network proceses?

	Hi Laaca. I have some sample executables that I used while developing the IP stack and FTP support. I have uploaded them here: http://bnhof.de/~ho1459/files/samples.rar You should try dhcptest or ping. Both display a lot of statistics on the network setup. I guess this should help us to find the reason for the failing GethostbyName() call. Thank you for your time, Stefan / AH

Ok, parameters are not supported if func=2, but statistics should work
here too, as they did after sending the first packets...

Hm, it seems that the software was able to detect the DHCP server.
I have added debug code to the DHCP code.
Please try this:

The parsing of the cfg file also seems to work.

Strange, let's see what the new tool shows (I guess it is stopping on
the DHCP request...).

OK, I tested the new version of your DHCPTEST.
With disabled WATTCP.CFG:

Here I see a potential problem but I am not sure if it can be called "bug"
The "DNS server" shows my secondary server not the primary one.
This is fragment of my WATTCP.CFG file with original comments:
--------------------------------------------------------------------

# fastest or closest name-server first for best result.
#
nameserver = 195.47.47.2 ; primary DNS, mandatory if not using DHCP
nameserver = 217.71.128.8 ; secondary DNS, optional

Apparently it does read the DHCP server but then exits when trying
to read the other parameters...

The config parsing of NDN is pretty modular and flexible but behaves quite simple in this case: it overwrites the previously parsed parameters with new ones if another parameter of the same type is found.
Maybe it should save only the first occurance?!

But this can't be the problem we have here,
I think that the packet handling is broken.
The PCIPKT driver behaves different from the drivers I know.

I have uploaded a new version of dhcptest:
http://bnhof.de/~ho1459/files/dhcp01.rar

Besides the screen output there wil be a debug file on drive C:\ called
vp_debug.txt. The output of the file is probably too big to post it here.

I think it is enough if you only do the DHCP test with wattcp.cfg disabled,
since the fix to the DHCP problem might also fix the problem if all parameters
are parsed via wattcp.cfg.

Thanks a lot for your help,
Stefan / AH

I don't use Linux much except to screw around on liveCDs occasionally, but I did download NDN for that "just in case." However, I don't see the binary! I think you left it out!

It works for me.

> The rest should work out of the box.

Probably - if one can recall the strange "#:" syntax ( I needed about 10 minutes for that ).

I also tried to connect to my site, which requires a userid+password. This "didn't work" first, NDN was able to connect, but an empty panel was shown only. I then left NDN and removed the entry in file ftp.ini. When I restarted NDN, it automatically tried to connect again to my site and this time it was able to show the contents!?! This is a slightly "unexpected" behavior.

"Strange"? :P
It fit's into NDN quite well - I couldn't have done it much better I guess. :P
You can also open directories or VFS' via ALT-F1/F2.

I think this has nothing to do with the FTP.INI editing.
Probably the directory parsing has failed.
CTRL-R to reread the directory probably would have also solved the problem.

The main problem is not that it did show an empty directory first, the main - security - problem is that NDN obviously caches userid + password and still remembers them even after I deleted the entry in ftp.ini.

Admittedly one can argue that the FTP protocol is inherently insecure and therefore this unwanted "restoration" of sensible data isn't such an issue, but still...

Ah, I see:
When you quit NDN while having an FTP connection open the FTP data
is saved to the desktop file, and restored on restarting NDN.
On my todo list is a plan for encryption of passwords etc.
Maybe even better the complete URL in case of FTP.
But I don't know when or how... :P

It's an inconsistent user interface. There is such a huge menu system in NDN which is supposed to navigate through all of NDN's features, but to open the FTP dialog you need to enter a cmdline command.

As an example for a consistent user interface see "Far Manager": There's an FTP entry in the menu which is opened with ALT-F1/F2.

NDN behaves very consistently:
a) Open drives/VFS/directories via ALT-F1/F2
In Options.File Manager.Setup.Behaviour you will find the option
"[ALT-F~1~/F2] Show VFS" - turn it on.

b) Open drives/VFS via the driveline with the mouse
Enable "Show VFS on Driveline" in the same configuration menu.
You should now see something like this:
[ C D E F G H I J K L M N X Z * ? # : ]

c) Open drives from the command line:
C: for drive C
*: for the temp VFS
#: for FTP...

If you want you might as well type the ftp URL on the command line
and NDN will try to connect to the server instantly.

I don't want to argue about the correct historical context on which
file manager existed first and what file manager introduced which
features first. ;)

The "historical context" isn't that interesting. Relevant is the current status. And currently FM has this option enabled by default while NDN has it disabled - and an occasional user like me is very unlikely to ever find the correct way how to enable it ... without professional help. :-D

One problem is that old (N)DN users don't like changes. :P
Many features that I enabled by default in the past because I
considered them quite useful resulted in complains by users...

I guess I should go through a virgin install of NDN and check what
useful options are disabled by default, then asking the users if they
mind if I enable them.

Thanks for making me think about that and for testing the FTP client.
