pveproxy not running on ipv4

[markc]

I just did a cli update and now pveproxy is not running on the ipv4 interface. Any suggestions?

~ netstat -tanup | grep 8006
tcp6 0 0 :::8006 :::* LISTEN 4503/pveproxy

~ pveversion
pve-manager/7.0-13/7aa7e488 (running kernel: 5.11.22-5-pve)

~ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.20.21 pve1.goldcoast.org pve1
192.168.20.22 pve2.goldcoast.org pve2

~ uname -n
pve2

~ sysctl -p
vm.swappiness = 90
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

# desperate attempt above to disable ipv6

From what version? Did you actually try to connect to the pVE interface and that does not work anymore or is this just an assumption from the netstat output? as that looks actually OK

netstat -tanup | grep 8006
tcp6 0 0 :::8006 :::* LISTEN 4503/pveproxy

This is fine, PVE nowadays listens on the any-wildcard address that maps IPv4 into IPv6 address, it looks the same here and I know for a fact that I can still connect over IPv4 too.

I'd rather check the more modern socket stat tool ss, it better shows that fact with less confusion, e.g. here:

ss -tlp | grep 8006
LISTEN 0      128                                     *:8006              *:*    users:(("pveproxy",pid=23845,fd=6) ... )

# desperate attempt above to disable ipv6

You normally do not want to do such things, that often has a big load of unexpected side effects all over the place, I'd highly recommend dropping those sysctls.
