Description Patrik Kis 2012-09-04 08:03:03 UTC

Description of problem:
While vsftpd supports IPv6 on RHEL-5 it seems ftp (the client) does not.

Version-Release number of selected component (if applicable):
ftp-0.17-37.el5

How reproducible:
always

Steps to Reproduce:
1. Enable IPv6 in vsftpd ad start the daemon
# netstat -na | grep :21
tcp        0      0 :::21                       :::*                        LISTEN      

2. Connect via ftp
# ftp 2000:dead:beef:a:5054:ff:fe68:13d4
ftp: 2000:dead:beef:a:5054:ff:fe68:13d4: unknown host
ftp> bye
# ftp ::1
ftp: ::1: unknown host
ftp> bye

3. The connection was verified from RHEL-6 ftp client and it worked.
  
Actual results:

Comment 3 Jan Synacek 2012-10-02 11:54:19 UTC

Please, make sure you are using ftp client from the 'ftp' package, not the kerberized version.

# which ftp
/usr/kerberos/bin/ftp

This version is from krb5 package and it probably doesn't support ipv6.

The client from 'ftp' package does support ipv6:

# /usr/bin/ftp ::1
< connection ok >
