Hi,
   I have migrated my redhat Enterprise linux server 5.5 to ipv6 . Now I want to run tacacs+ for Ipv6. When I testing from my client, it return unable to connect to server for IPv6 address. But for Ipv4 it's working fine.

Snapshot of Linux listening port:

[root at ADA-Linux-Service-2 ~]# netstat -an | grep :49
tcp        0      0 0.0.0.0:49                  0.0.0.0:*                   LISTEN

And once the tacacs service is started, I tried using the bind option with IPv6 it returns following error.

Reading config
Version F4.0.4.26 Initialized 1
get_socket: bind 49 Address already in use

                I don't know how to make tacacs+ to listen on IPv6 address. Or is that I need to do any entries in tac_plus.cfg to listen for IPv6.


Regards,
MK
