Quoth [EMAIL PROTECTED] (Jeffrey Altman):
| You need to use an FTP client that allows you to disable the use
| of channel bindings. See C-Kermit
|
| http://www.kermit-project.org/ckermit.html
|
| It will do what you need when the command
|
| SET AUTH K5 NO-ADDR ON
You also need a patched ftpd, right? Or does the GSS ftpd from
the current MIT release now support clients from behind a NAT?
