I've installed proxy-suite on sun OS 5.8 and each time I do a download of a file ~ > 1 Meg, I have a broken pipe error. I've already tested several configuration of the product but the problem is always the same.
The trace in the ftp-proxy.log is the following: ftp-child [21938] <03/13-09:33:31> TECH-ERR can't read from 4=159.140.3.145 where 159.140.3.145 is the ftp destination address.
Below, I give more details I've used the sources in ftp.suse.com/pub/projects/proxy-suite/proxy-suite-1.7.tar.gz and I encounter this problem. I 've also tried with ftp.suse.com/pub/projects/proxy-suite/proxy-suite-1.7tp5-src_patched.tar.gz but it didn't change anything. I didn't find the patch you told in the devel directory. Is it the .rpm file which is a binary distribution ? How can I install it on my sun OS machine ? I give you my configuration file which is very simple ##################################################################### # # $Id: ftp-proxy.conf.sample,v 1.3 1999/09/24 06:39:43 wiegand Exp $ # # Sample FTP Proxy Configuration File # # The general format is "Keyword Value". # # Any white space at the beginning or end of a line and after # the Keyword is ignored.

In order to avoid confusing the # configuration reading functions, the expression is "pre- # processed." This means that a sequence like "%20" will be # replaced by a space and "%5c" or "%5C" by a backslash # before being compiled. In fact, this looks a bit like the # HTML way of doing things. The percent sign itself is # represented by "%25" of course. The pattern is interpreted # as a POSIX 1003.2 RE (with REG_NEWLINE flag set), and is # case sensitive.
