Hello,

Hi,
The issue may occur, if FTP client uses CONNECT method to connect to
remote FTP servers. You can find details in the following thread:
http://www.squid-cache.org/mail-archive/squid-users/200609/0111.html
If your FTP client connects to Squid's http_port then it uses CONNECT
method. To solve the problem try to use ftp_port and disable proxy
settings on FTP client.
For example:
1. Configure ftp_port.
# diff etc/squid.conf.default etc/squid.conf
59a60
ftp_port 21
2. Connect from FTP client, where:
${squid_ip} - Squid's IP address
${squid_ftp_port} - configured ftp_port
${username} - username on remote FTP server
${ftp_server} - remote FTP server name/IP
${password} - password for remote FTP server
$ ftp ${squid_ip} ${squid_ftp_port}
Connected to localhost.localdomain.

Name (localhost:garry): ${username}@${ftp_server}
