Subject: use better regex for remote ip check
X-Git-Url: https://git.proxmox.com/?p=pve-common.git;a=commitdiff_plain;h=cca9492eb4e7226142ac36eaf637f3dd76570c45

use better regex for remote ip check

while the input should be correctly generated by the other site its
still better to be on the safe side, so check if the IP is really an
valid one.
