[pbs-devel] [PATCH proxmox-backup 2/4] require square brackets for ipv6 addresses

[Dominik Csapak <d.csapak@proxmox.com>]

we need this, because we append the port to this to get a target url
e.g. we print

format!("https://{}:8007/", address)

if address is now an ipv6 (e.g. fe80::1) it would become

https://fe80::1:8007/ which is a valid ipv6 on its own

by using square brackets we get:

https://[fe80::1]:8007/ which now connects to the correct ip/port

 The default value for ``username`` ist ``root@pam``.  If no server is specified,
 the default is the local host (``localhost``).
 
+Note that if the server is an IPv6 address, you have to write it with
+square brackets (e.g. [fe80::01]).

 You can pass the repository with the ``--repository`` command
 line option, or by setting the ``PBS_REPOSITORY`` environment
 variable.
