I have just installed my first CentOS 5 server. I run proftpd on the server and I am getting a lot of warnings about IPV6 things. I do not have ip6tables turned on, but figure there is something else I have not done properly.
A few of the errors are like:
Deprecated pam_stack module called from service "proftpd" pam_unix(proftpd:session): session opened for user steve by (uid=0) Deprecated pam_stack module called from service "proftpd" library2.cnpapers.com (::ffff:216.30.205.128[::ffff:216.30.205.128]) - error setting IPV6_V6ONLY: Protocol not available
I also see, when I do an ifconfig, references to inet6 lines such as
inet6 addr: ::1/128 Scope:Host
for my loopback and similar lines for my eth devices.
Am I in trouble and is there something I need to do?
Thanks for any help.
