Arno Unkrig updated NET-508:
----------------------------
Description:
The COMMONS-NET FTP client supports 'FTP over HTTP', but not the other popular
FTP proxy schemes. The article
http://www.codeproject.com/Articles/9547/How-Proxy-Server-serves-FTP-clients
describes some of them, but not very precisely an obviously a bit incorrect.
I added proxy support for the ANT FTP task in
https://svn.code.sf.net/p/loggifier/code/trunk/ant_issue_54883/src/org/apache/tools/ant/taskdefs/optional/net2/FTP2.java
(search for string "proxyServer"), but I believe that the feature should be
implemented in COMMONS-NET, not in the application, maybe like this:
{code}
connectToProxyAndLogin(server, port, userid, password, proxyServer, proxyPort,
proxyUserid, proxyPassword)
{code}
The proxy server that I (must) use is
{noformat}
220 McAfee Web Gateway 7.2.0 build 13935
{noformat}
, and from experiments it supports the following authentication schemes:
{noformat}
(1) USER pu PASS pp OPEN ftp.acme.com[:port] USER u PASS p
(2) USER pu PASS pp USER [email protected][:port]
PASS p
(3) USER pu PASS pp SITE ftp.acme.com[:port] USER u PASS p
{noformat}
I don't know which FTP proxy servers support which of these flavors, but (2)
appears to be the most natural and robust to me.
