 Posted: Sat Nov 16, 2019 6:31 pm Post subject: [solved] resolv.conf no longer gets populated while booting |
 |
|
After a reboot on my server, which is configured with fixed IP, apparently net.eth0 does no longer add nameserver entries into resolv.conf.
resolv.conf looks like this then:
| Code: | # Generated by net-scripts for interface lo
domain mydomain.com
search myhostersdomain.com |
| Code: | /etc/init.d/net.eth0 status
* status: started |
/etc/conf.d/net
| Code: | config_eth0="123.456.789.87 netmask 255.255.255.0"
routes_eth0="default via 123.456.789.1"
dns_servers_eth0="127.0.0.1"
dns_search="myhosterdomain.com"
dns_domain_lo="mydomain.com" |
But after restarting net.eth0 manually by issuing /etc/init.d/net.eth0 restart resolv.conf is populated with nameserver entries.
Where could that come from?

dmesg
dns still works as ping google.ch translates correctly. Probably because of unbound. I got aware of this as starting rspamd service, I saw a message:
| Code: | /etc/init.d/rspamd restart
cannot parse resolv.conf and no nameservers defined, so no ways to resolve addresses
* Stopping rspamd ... [ ok ]
* Starting rspamd ... [ ok ]

I think that your resolv.conf got overwritten by bringing up net.lo.
I had this when installing rspamd - which in turn required redis, which in it's /etc/conf.d/redis (iirc) needs net.lo (which means that it'll get started if not running) - I changed that to need my net.Eth1 instead (as I also changed redis/the rspamd worker-controller to listen on that interface) |

Perfect.
So I changed /etc/conf.d/redis to listen to net.eth0 here too.
I then added
listen = "net.eth0" to /etc/rspamd/worker-controller.inc
hoping that this is what you meant 
Rebooting showed nameserver entry in resolv.conf as expected thus rspamd not complaining anymore that it could not parse resolv.conf.
Thanks  |

Not exactly,
You shouldn't edit /etc/rspamd/worker-controller.inc - it'll be overwritten with rpsamd-updates/re-emerges. Instead you'll want to edit/create /etc/rspamd/local.d/worker-controller.inc and have a linewith the hostname or ip + port you wan't to listen on ie. | Code: | | bind_socket = "mail.vlh.dk:11334"; |
in /etc/conf.d/redis I have because that's the interface providing the needed ip. (I've removed the rc_need="net.lo" line completely - dunno if you did that) |
