Re^3: Net::ftp && IPv6

when I do a small change (hardcoded, just for test) in Net/INET6Glue/FTP.pm:

$ diff /usr/local/sisis-pap/perl5.16.2/lib/site_perl/5.16.2/Net/INET6G
+lue/FTP.pm*
30c30
<                       LocalAddr => $ftp->sockhost,
---
>                       LocalAddr => 'fe80::250:56ff:feb6:5310%eth0'
[download]

the transfer of the data works:

Net::FTP=GLOB(0x83b0080)<<< 150 Here comes the directory listing.
Net::FTP=GLOB(0x83b0080)<<< 226 Directory send OK.
file: file
file: tr
Net::FTP=GLOB(0x83b0080)>>> EPRT |2|fe80::250:56ff:feb6:5310|35672|
Net::FTP=GLOB(0x83b0080)<<< 200 EPRT command successful. Consider usin
+g EPSV.
Net::FTP=GLOB(0x83b0080)>>> RETR file
Net::FTP=GLOB(0x83b0080)<<< 150 Opening BINARY mode data connection fo
+r file (12 bytes).
Net::FTP=GLOB(0x83b0080)<<< 226 File send OK.
Net::FTP=GLOB(0x83b0080)>>> QUIT
Net::FTP=GLOB(0x83b0080)<<< 221 Goodbye.

this underpins that somehow on the way down the %eth0 is droped off the $ftp->sockhost;

Strange. It all just works here in passive mode, and the non-passive case is explainable. When I add the following print to your code, i get the %eth0: `my $ftp = Net::FTP->new($ipaddr, Debug=>1, Passive=>1) or die "Can't c +onnect: $@\n"; print $ftp->sockhost;` [download] I'm guessing by this point it's already missing for you? Using Net::FTP 3.02 and IO::Socket::INET is 1.35 here. As a digression, my ifconfig shows a scope id of "2" for my eth0 device. When I then use %2 at the end of the ip address, Net::FTP automatically replaces it with %eth0. While that's new to me, it's obviously supported. However Net::FTP violates RFC 2428 by including that in the EPRT command in the non-passive case. I had to do rule rewriting in my Proftpd server to strip it off before things would work.

After updating libnet to version 3.02 and IO-Socket-IP to 0.32 it works as it should, $ftp->sockhost returns the IP addr with the %eth0 at the end and FTP works fine; Thread end, thanks	[reply]
