I've been trying to use our Squid server to proxy FTP traffic.
The client is FileZilla. It is configured to use the squid server as
an HTTP 1.1 proxy.
I can connect to a remote site without difficulty (yes, I have to
enable the CONNECT method for this). The remote site has an idle
timeout of 15 minutes.
Everything works fine until I try to send a file to the remote site.
When sending a file (FTP STOR command) the transfer is cut at exactly
15 minutes. FileZilla reports that it detected a timeout and has
disconnected from the server.
If I bypass the Squid server then I can send the file (which takes
about 18 minutes to transmit) without difficulty.
There doesn't appear to be a problem fetching files, only sending them.
Can anyone shed any light as to possible reasons? I've RTFM and
checked this mailing list archive but have drawn a blank so far. I
can't see anything in our squid.conf which would cause a timeout when
tunnelling FTP.
Squid version is squid-2.5.STABLE5-42.47 (as distributed with SLES 9).
Thanks,
Jeremy
