Noon,

Here's my scenario:

- 2 offices, both of them running Suse 10.1 as their firewalls/proxy;
- I'm in office A, trying to access a FTP site (Windows) in office B;
- In office A, FTP is set to use the proxy (Squid - configured in the browser);
- The FTP site in office B requires authentication.

Now, here what's happening:

- When I access the FTP site from an external site (my house), everything works fine: the browser shows me the FTP authentication window, I log in;
- When I try to access the FTP site from inside office A (using the proxy) I get the following message:

and no authentication window.

Tried access.log, didn't help much.

So ahn... help?

acl ftp_server dst x.x.x.x
always_direct allow ftp_server



Just bypass proxy for that server.. while you figure out the real reason its failing.

Unfortunetly, that didn't work

Ahh.. I remember now,

Squid is an HTTP proxy only.. FTP is sort of fudged, you may have to add the FTP username as a squid directive.

Although, I don't think this will help with authentication.. your better off shovelling it through a VPN. (or just using sftp/ssh+sftp etc)
