 |
|
Hi,
I'd like to know why the loopback interface does not get an IPv6 address at boot time, but it does if I manually restart it.
| Code: | # rc-update show | grep net.lo
net.lo | default
# sysctl net.ipv6.conf.lo.disable_ipv6
net.ipv6.conf.lo.disable_ipv6 = 0
# /etc/init.d/net.lo status
* status: started
# ip a s lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
valid_lft forever preferred_lft forever
# /etc/init.d/net.lo restart
* Bringing down interface lo
* Bringing up interface lo
* 127.0.0.1/8 ... [ ok ]
* Adding routes
* 127.0.0.0/8 via 127.0.0.1 ... [ ok ]
# ip a s lo
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever |

| Do you have something else like NetworkManager possibly interfering with it? |

| Do you have IPv6 builtin statically or as a module? |

As a module:
Network tries to set up before module is loaded?
How can I avoid that? |
