Troubleshooting

I can't connect to Cobalt's FTP server

If you're running Cobalt in VirtualBox, you should check the Network settings. Make sure the Cobalt virtual machine is selected in the main VirtualBox window, and click Settings. Then click on the Network menu option, and click the arrow net to Advanced to see all the options. Your network settings should look like this:

You have to change 'Attached to' to 'Bridged Adapter,' so the FTP server is visible to other devices on your local network (including the host computer). After you change these settings, start up the Cobalt virtual machine and run this command:

newip

This will obtain a new IP address. Everything should work now!

The message "mTCP: IPADDR must be set" shows up when I run FTPSRV

This means the DHCP program did not automatically obtain an IP address for some reason. Try running this command:

newip

After the program is finished, try running FTPSRV again. If it still doesn't work, you'll have to manually set an IP address in the MTCPCFG.TXT file. You can do that by typing in this command:

edit \SYSTEM\NET\MTCPCFG.TXT

Then scroll down until you see #ftpsrv_ext_ipaddr. Delete the pound sign (#) from the start of the line, and replace some.ip.addr.here with a valid IP address for your network.
