Hi Dan, Yes my thoughts exactly I've tried numerous ways including the gai.conf mod to 'disable' IPv6 on 9.2 none seem all that successful in 9.2. e.g. root@backup:/home/xxxx# cat /etc/gai.conf # Configuration for getaddrinfo(3). # ... ... ... # #precedence ::1/128 50 #precedence ::/0 40 #precedence 2002::/16 30 #precedence ::/96 20 #precedence ::ffff:0:0/96 10 # # For sites which prefer IPv4 connections change the last line to # precedence ::ffff:0:0/96 100 # # scopev4 <mask> <value> # Add another rule to the RFC 6724 scope table for IPv4 addresses. ... ... ... #scopev4 ::ffff:127.0.0.0/104 2 #scopev4 ::ffff:0.0.0.0/96 14 root@backup:/home/xxxx# ip ad 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether ca:57:82:c2:51:ad brd ff:ff:ff:ff:ff:ff inet 172.16.11.22/24 brd 172.16.11.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::c857:82ff:fec2:51ad/64 scope link valid_lft forever preferred_lft forever root@backup:/home/xxxx# root@backup:/home/xxxx# ping www.google.com
