[SOLVED] mail gateway service pmgbanner.service + pmgpolicy.service + pmgsync.service fail to start at boot with a dynamic ip

[abma]

The services fail to start at system boot:

Sep 03 10:42:58 servername pmgbanner[42970]: Use of uninitialized value $ip in concatenation (.) or string at /usr/share/perl5/PVE/Network.pm line 645.

proxmox-mailgateway 7.0-1


when i restart the services manually it seems to work: i guess the network/dns is up after the services are started?

please post:
* /etc/network/interfaces
* /etc/hostname
* /etc/hosts
* /etc/resolv.conf

that should give us a better overview where the issue might be rooted

 

[abma]

/etc/network/interfaces is empty, instead:
/etc/systemd/network/50-wired-network:

[Match]
Name=e*

[Network]
DHCP=ipv4

[DHCP]
ClientIdentifier=mac
SendHostname=true
UseDomains=true

/etc/hostname:

servername

/etc/hosts:

127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

/etc/resolv.conf:

domain somedomain.de
search somedomain.de
nameserver 192.168.101.249
nameserver 192.168.101.251

Is the IP truly dynamic (which I'd consider odd for an smtp-server)?
If not - please add an entry to /etc/hosts pointing the short and long hostname to the ip

 

[abma]

Is the IP truly dynamic (which I'd consider odd for an smtp-server)?

atm yes: we are testing functionality.

 

[Stoiko Ivanov]

PMG needs a static (or at least resolvable) IP - see https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmg_install_on_debian_container

I hope this helps!

IMHO the .service are IMHO invalid, i.e.:

[Unit]
Description=Proxmox Mail Gateway Login Banner
ConditionPathExists=/usr/bin/pmgbanner
DefaultDependencies=no
After=local-fs.target
Before=console-getty.service

it should be something like:

[Unit]
Description=Proxmox Mail Gateway Login Banner
ConditionPathExists=/usr/bin/pmgbanner
DefaultDependencies=no
After=network-online.target
Wants=network-online.target

running mail gateway services without net isn't useful i guess. the documentation seems wrong: atm it requires a static network config/ip.

IMHO the .service are IMHO invalid, i.e.:

does it start successfully with your proposed changes?

 

[abma]

does it start successfully with your proposed changes?

yes! the failures where quiet random it seems: very likely it depends on how fast the dhcp server answers. to make the changes apply, i had to run:

for i in pmgbanner.service pmgpolicy.service pmgsync.service; do systemctl reenable $i; done;
