proxmox-backup-proxy trying to open an INET6 socket... on an IPv4 only server

[jaxx]

Hi all,

I wanted to give PBS a look, but the proxy daemon didn't want to cooperate with me, and seems to not have any configurable options to help.

It seems to be harcoded to open a socket on ::

readlink("/proc/self/exe", "/usr/lib/x86_64-linux-gnu/proxmo"..., 256) = 61
socket(AF_INET6, SOCK_STREAM|SOCK_CLOEXEC|SOCK_NONBLOCK, IPPROTO_IP) = -1 EAFNOSUPPORT (Address family not supported by protocol)

Thus, not working on a machine where IPv6 is fully disabled. We don't need it, therefore, it's hard disabled at grub ipv6.disable=1, one less thing to worry about.

Would it be doable to have either a conf file, or an option to have it comply ?

As much as I love IPv6, we have it on most of our front facing services, but we cut it off when not pertinent, and to quote a friend "It's a technology for the future, and it will remain that way" ;-)

Thanks,
JaXX./.

If you disable ipv6 via sysctl you should be fine. There's indeed an issue with disabling ipv6 via grub.

Considering that we're getting closer and closer to that future that wouldn't come, your policy might cause you to have more of these issues

Considering that we're getting closer and closer to that future that wouldn't come, your policy might cause you to have more of these issues . Maybe time to reconsider this disabling policy. One thing less to worry about would become "Why doesn't this piece of software that did adopt the future work for me!?".
