Print Page - Cannot assign requested address

Title: Cannot assign requested address
Post by: jzS6qNc on 08 October 2022, 01:31:50

I updated my system few days ago and since then several programs report that they can't assign address.
jupyter says:

OSError: [Errno 99] Cannot assign requested address

mpd says:

Code: [Select]

exception: Failed to bind to '127.0.0.1:6600'; Failed to bind socket: Cannot assign requested address

I tried other ports.
I'm on "5.19.12.artix1-1" and runit.

Just a hunch but is localhost up ?

What is the output of

Code: [Select]

ip addr show

Code: [Select]

Hmmm not good, your info about your loopback interface is missing a very important line:

Code: [Select]

inet 127.0.0.1/8 brd 127.255.255.255 scope host lo

Do a google search and see how you can assign 127.0.0.1 to your loopback interface and then see if the problem still persists.

It shows the loopback interface is down:

Code: [Select]

1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

eth0 is down but only an issue if you use a wired connection at all.

Which init do you use?

It could be just the service that brings it up is not enabled or something more underlying ?

Borrowed from openrc's loopback service file,

Code: [Select]

sudo ip addr add 127.0.0.1/8 dev lo brd +
sudo ip link set lo up

As a short term fix that might bring up the loopback interface.
If it doesn't post any error messages.

Edit: I just remembered there was a library mismatch recently causing issues with the iproute2 suite of programs. I think this is related to that.
Try updating again.

I'm on runit but what you wrote seems to have solved the issues. Thank you.
