[K12OSN] Creating a repository in a K12LTSP server

[Mike Oliveri]

Samba should work, but without seeing your smb.conf it would be hard to
tell you where the trouble is.

For vsftpd, you'll want to review your configuration there, too. First I
assume you've got the daemon running, but sometimes the defaults are
locked down. I'm using vsftpd on a Slackware box and I'm able to connect
with Firefox just fine. Check these settings:

local_enable=YES
If this is NO, then nobody can log in. I think the default was NO in
Slackware.

write_enable=YES
Probably only needed if they're uploading files back to the box.

connect_from_port_20=YES
I don't recall ever having to change this, but can't hurt in case that's
what Firefox is looking for...

I would bet the first is the culprit. The vs in vsftpd is "very secure"
so it's very likely it's locked down out of the box. Remember to restart
the service/daemon if you make any changes!

Are you trying to avoid having them download extra software? Another
simple solution would be to use WinSCP (http://winscp.net/eng/index.php)
on the Windows laptops and maybe Fugu
(http://rsug.itd.umich.edu/software/fugu/) for the Macs.

Take care,
Mike
