Re: [squid-users] no FTP proxy available?

as far as i know, frox does not support user authentication.
to make that clear again. i must have authentication on the ftp proxy.
an i found out, that no proxy in the unix world supports parent ftp proxies
and user authentication. ftp-proxy supports user authentication but no
parent proxies. frox suports parent but no user authentication.
i'm looking already sme time for a proxy that supports both features but
there is none. so i thought maybe squid could do the trick with a little
tweaking the configuration. also because it would be possible to use the
same user database. any expirences are welcome.

i search already a lot and saw all this proxies.
there is no need for http support. squid can do this. i only need an extra
ftp
proxy. but the problem is they all can't support parent und
userauthentication
in combination.

well, i checked that out and it seems that you have to find a client which
then also supports this. are put's also supported over http?

well, i don't will change the setup for scanning. setup is as
intranet -> ftp proxy -> viruswall -> internet

i tried an "good" ftp client. also gftp and both had problem with listing
directories and uploading files. any hint on an graphical unix client that
supports ftp over http with a parent proxy. or can someone give me an
config example for FTP and squid using a different parent than for http.
so i can try this out again.
