Connection Manager generates empty resolv.conf at boot, breaks cheevos

[webodan]

Hi,

I'm running recalbox 4.1 with manual IP settings. I've got them written in a custom.sh file using connmanctl commands as written in the wiki.

My problem is that regardless of me manually editing /etc/resolv.conf with opendns nameservers then running ifdown eth0 && ifup eth0, the system will ignore this and rewrite an empty resolv.conf file, which I've noticed breaks retroachievements/cheevos support. It's a major nag to have to log into the system every time over SSH to fix this, so there must be a better solution that I haven't found. I've never used this connman thing so it's quite confusing, am I missing something?

Thanks in advance.

@webodan we're all missing how dns resokution is made in such case. No gateway problems ?

@substring I've been trying some more, let me explain the problem better:

Typing in /usr/bin/connmanctl config ethernet_b827ebba8c1e_cable --ipv4 manual [IP] [netmask] [gateway] --nameservers 208.67.222.222 TWICE through the command line works (one changes the ip and the second time seems to get the nameserver to resolve properly) works, but when i put it in my /etc/init.d/S99custom file after #!/bin/bash it seems to ignore the nameserver part, as it does assign the IP properly but it will not resolve.

edit: i've just tried putting in that command twice in my file, with sleep 5s in between but nope, it doesn't care i have to ssh every time to get the nameserver to work. and the file is being run fine on boot because i put in a touch command just to make sure it wasn't my fault setting this up.

so to recap: after rebooting my machine with the custom file written like this:

#!/bin/bash
/usr/bin/connmanctl config ethernet_b827ebba8c1e_cable --ipv4 manual [IP] [netmask] [gateway] --nameservers 208.67.222.222
sleep 5s
/usr/bin/connmanctl config ethernet_b827ebba8c1e_cable --ipv4 manual [IP] [netmask] [gateway] --nameservers 208.67.222.222

... breaks the nameserver, and SSHing into the machine (which has the IP address i gave it with connmanctl properly set, so it's not entirely ignoring me) then running nslookup google.com returns 127.0.0.1 as the nameserver (????????).

oh yeah, and also, if i put the aforementioned command in the custom file just once it also doesn't work. that's why I started experimenting with maybe putting it twice.

THEN over ssh if I run the conmanctl command that i've put in the custom file, that's when it resolves nslookup perfectly and the achievements work.

i'm confused as f**k right now

and yeah i kinda have gateway problems that's why i set everything manually, but everything i have works after i've set static ip addresses.

@webodan using static dhcp would be so less less less painful
