Barts DOS Network Boot disk not authenticating

[frontrange]

Greetings - I have a problem with passing credentials from a DOS PC running Bart's Network Boot disk which I think is basically the WfW stack on DOS.

A little history on the problem as follows. I have a large CNC milling machine that runs a proprietary machine control software under barebones DOS. In order to be able to pass files that I create on a modern PC running CAD/CAM software to the old DOS based machine I have been running the Bart's network software for years on the milling machine, connecting to a Windows XP fileserver.

With the support for XP going away, I tried doing the share off of a Vista machine, but couldn't get it to connect (authenticate) and after researching all of the possible registry settings I might need to change, I decided to try a NAS server instead thinking control of what protocol levels would be supported would be easier than fiddling with inscrutable windows registry entries.

I have installed FreeNAS, created a share, created an account with password, and checked protocol support to include everything on the CIFS menu going back to LANMAN1 and still no joy.

Every time I try to log in from the Bart's DOS system I get a message that the password is wrong. I use the exact same username and password from a modern PC and all is good. I have set logging to debug, but I see no tab under the GUI for debug events and I see nothing getting posted to the freenas server syslog when I try to authenticate from the DOS machine.

Any advice on next step to isolate where the problem may be?? TIA

Did you ever make any headway with this?

No, I had to stand up another server on XP just to provide this network share. I tried every possible option on FreeNES without any progress and never found out where debug logs are written.

The log you are looking for is probably /var/log/samba4/log.smbd
If you set it to debug then be prepared to wade through lots of info.

You can perform a packet capture when it's trying to authenticate. By running the following command from terminal.

tcpdump -w /mnt/Tank/foo.pcap

Replacing 'tank' with the name of your zvol. Then run the pcap through wireshark on a separate machine.

You can compare that with a pcap from the windows machine when it successfully authenticates.

Additionally, you can try a vanilla install of FreeBSD using samba 3.6 and see if it works there.

Lost interest at this point. Eventually I need to migrate the CNC hardware from the current proprietary system to LinuxCNC. At that point I won't need to support the old WFW protocol stack. In the mean time, I'll live with the old XP server doing nothing but serving this network share.
