Description Vladimir Kotal 2003-10-21 14:15:45 UTC 
1.2.9rc3 compiled on FreeBSD-4.7 RELEASE with '#define USE_IPV6 1' in config.h
produces invalid 'address mismatch' messages like this:

Oct 20 22:41:14 ftp proftpd[61474]: IP1 (IP2[IP2]) - 
Refused PORT IP2,4,139 (address mismatch) 
  
this comes from modules/mod_core.c, around line 3119.

when I added debug messages to src/netaddr.c to see what is the problem, 
I got -2 return value. see the patch for details. 

the output were then like this:

Oct 21 20:06:47 ftp proftpd[5045]: IP1 (IP4[IP4]) - A 28 (null) 2 IP4
Oct 21 20:06:47 ftp proftpd[5045]: IP1 (IP4[IP4]) - Refused PORT IP4,4,15 (-2 ad

Current CVS sources should have this issue fixed.
Comment 4 TJ Saunders 2003-10-24 13:27:07 UTC 
Can you confirm that this problem is fixed in current CVS?

seems to be working with both EPRT and EPSV with current as of today.
Comment 6 TJ Saunders 2003-10-26 20:11:50 UTC 
What about PORT?

seems to be working:

lftp ftp:/pub> get 00index.txt
